Customers commonly describe Allied Welsh Loft Conversions Ltd as professional, friendly and polite, with clear communication and updates; some note the use of in-house teams rather than subcontractors. Several customers report high-standard workmanship, tidy sites and daily clean-up, and some say projects were completed on time or within the stated timescale. Dean is named in several accounts as a project manager or team leader who was available for queries; one customer says he came out at a weekend for a last-minute change. One customer reported that after-sales help years later included replacing a roof tile and providing a building regs certificate without charge; another reported a roof leak fixed two years after completion. One customer said Allied Welsh never replied to an email enquiry.
Very professional, hard working, and they take pride in their work. Couldn't ask for much more from our loft conversion. I have no problem recommending Allied Welsh, a thoroughly trustworthy company.
A fantastic, professional and organised service from start to finish. The whole team were competent, reliable, hard working and experienced. Our project was managed by Dean, who was available at all hours and nothing was too much trouble. All other contractors involved were so impressed with the work of Allied and how quickly the project was finalised to a high standard. Highly recommend.
You rarely, if ever, see after-sales service as amazing as this! A few years after completing our loft conversion we had a leak. Allied Welsh came out straight away, replaced a roof tile, and did not charge a penny. Now, 21 years later, we needed the building regs certificate, and once again Allied Welsh came up trumps and wanted nothing in return. Thank you, Allied Welsh!
Excellent company from quote to completion. Great communication, clear break down of costs, the different teams throughout the build were great, on time, respectful of our home. They were managed by Dean, an excellent team leader and who let us know exactly who was in when, as we work full time and access to the property was sorted by Dean so we could continue working. Dean was conciencious about the little details such as;height of the Velux so I would be able to see out, symmetry of the cupboards and lighting best suited for the use of the space.They finish of the work was to an excellent standard and the ongoing customer care has been brilliant. Would absolutely recommend Allied Welsh.
Brilliant company - had our dormer installed a few years back - excellent at communication throughout the process responsive to queries and also resolved a couple of minor issues when they arose post construction. Would highly recommend.
We're so pleased we picked Allied Welsh to do our loft conversion, we were given the quote for the work at their initial visit so didn't have to wait for that to be sent and their surveyor visited very soon after for detailed plans to be drawn up. We felt confident too on meeting the owner who was able to respond to all our queries. All the men who came to the house were very skilled and the work progressed well. We were also kept up to date with what next actions would be taking place. What made a real impact though was how polite and responsive all the men were to our household. They went that extra mile to make sure we were happy with everything and I wholly recommend them and this company.
Great job! My loft conversion has just been completed. We had 2 new bedrooms and a bathroom completed in under 3 months. They have created a great space for us. Allied Welsh have been fantastic, very friendly, clean and easy to deal with throughout the whole process. The quality of the work has been outstanding. I highly recommend Allied Welsh. Thanks!
Can’t recommend Allied Welsh enough, very professional from start to finish, having a loft conversion is a stressful experience from work point of view and financial so a professional team is what you want for the job. I would have to praise Dean Evans from the team who always been brilliant, polite and very professional, he also always willing to walk the extra mile for the job, he even came in an evening of a weekend for our last minute change of plan to sort out and was very patient and professional. The whole team is very friendly and professional. Good job with the loft and the photos will say it all, many thanks Allied Welsh team
Allied Welsh are truly outstanding. Their professionalism is beyond 5 stars. They employ all of their teams (rather than subcontract) and are so on it with project management. They had said they would arrive on the 4th of June and leave the week of the 8th of August (planned a good 6 months ahead), and they did. They went above and beyond to deliver an outstanding service, fixing things throughout the house that had some connection to the loft (and even separate to the loft sometimes, ie a toilet mounted the wrong way around that had nothing to do with them). They even came back 2 years after to fix a leak in the roof.. They are so so professional, so reliable, it’s rare these days. Would recommend above and beyond
Fantastic experience with Allied Welsh on a recent loft conversion. Great communication throughout, guided us through the process from consultation, design, planning, construction and completion. Work was completed to a high standard in the time given (approx 5 weeks) and the process has been really efficient and smooth. They were accommodating when we requested additional tweaks and extras, great with my neighbour who had some initial concerns and totally transparent throughout. Great company and would happily recommend to anyone looking to extend or improve their property.
We would highly recommend Allied Welsh! They have recently completed our loft conversion and from beginning to end it has been a smooth and positive experience for us. The team is fantastic- everyone has been friendly and courteous and worked really hard. We are delighted with the end result. The communication has been excellent- thank you Dean for always being available for queries. Our questions have been answered throughout. Thank you all.
Allied Welsh completed our valley roof loft conversion and a shower room conversion a few months ago. From obtaining planning permission until the completion of the whole project, we couldn't be happier. They are extremely efficient (the whole project was finished in 2 month), professional, and tidy! The work was completed to a high standard. I highly recommend them.
Allied Welsh recently completed a loft extension on my house and came highly recommended and I would highly recommend Allied Welsh for a loft conversion and was so pleasantly surprised by how quickly and professionally they completed the job. All of the team are friendly, polite and respectful and were always on hand to answer any queries or requests, showing patience and expertise from start to finish. They also co ordinated and completed the fitting of a new bathroom, providing solid advice and finishing all jobs to the highest standard. I was always kept up to date with the plans and timeline each week so I knew what to expect and the whole project felt very hassle and stress free! Thank you very much!
From start to finish, Allied Welsh were absolutely brilliant when it came to our garage conversion. The team were pleasant, polite, turned up when they said they would and did everything as per the specification. They cleaned and tidied up after themselves too. They were a pleasure to have around. They’ve transformed what was a redundant and dark garage into a space we now plan to work from, freeing up space in our house. The quality of their work and service has been impressive. We highly recommend Dave, Dean, Mike, Dale, Lee, Rhys and all of the other team members who made things happen! Thank you! Diolch! 👏🏻
After deciding we wanted a loft extension and looking at a number of companies we decided on Allied Welsh. I’m glad we did. From the planning when we had some issues with the local authority which required some changes which Allied dealt with to the construction where everything went smoothly from our point of view. Professional, clean and accommodating I can’t speak highly enough of all the guys. To Dave, Dean, Mike and all the team at Allied Welsh a big thank you for giving us everything we wanted from our conversion we are delighted with the outcome.
I would highly recommend this business, there customer service is second to none. There work throughout my garage conversion exceeded my expectations, so much so that I was completely impressed with there professionalism, and would not hesitate to recommend them.
Allied Welsh recently completed our loft conversion and we are very happy with the finished result. The whole process was very smooth from start to finish and every single person we had contact with was professional and friendly. We wouldn’t hesitate to recommend.
We recently had Allied Welsh convert our garage into an additional room, and we couldn’t be happier with the results! From the initial quote and planning stage, the team was fantastic—clear, professional, and straightforward. Their pricing was very competitive, and every part of the project was carried out efficiently and with impressive attention to detail. All of the tradespeople were highly skilled, incredibly tidy, and respectful of our home. The work was completed on time and exactly as we envisioned. We’d highly recommend Allied Welsh to anyone looking for a reliable and high-quality service, and we would definitely use them again!
Would definitely recommend! From start to finish, they were professional, efficient, hardworking and clearly very knowledgeable. Super happy with our new loft conversion.
From the very start of this project to the final touches, the entire team at Allied Welsh has been nothing short of professional, helpful, and attentive to every detail. We are genuinely over the moon with how smoothly everything has gone, and we’re so grateful for the hard work and dedication shown by everyone involved. A huge thanks to each and every person who has contributed along the way. We are so thrilled with how the loft conversion has turned out. It’s truly looking amazing, and we couldn’t be happier with the results. Thanks so much for your fantastic service!
Could not recommend Allied Welsh more. Their professionalism was second to none and the results speak for themselves. They made everything so easy from start to finish, and the builders even bought our toddler a little birthday present, which was unexpected and super thoughtful. They were friendly, respectful, tidy and were blown away by their craftsmanship. Thank you so much!
Allied Welsh have just completed our loft extension, master bedroom with huge dormer window, bathroom and changing room with large Velux windows. It was a far from simple project not helped by us changing the layout. We looked at a number of companies but at the end of the day it was Allieds reputation dating back over 30 years and the fact they were finically stable (we checked their accounts on line before even contacting them). The staff from design though to all specialist tradesmen are employed unlike so many other companies so everything was kept under control. Finally every single member of the team were a pleasure to deal with. We have absolutely no hesitation in recommending them to anyone considering similar projects.
We would highly recommend Allied Welsh for a loft conversion. The whole process from design to completion was hassle free. Any concerns we had were dealt with immediately and efficiently throughout the entire process. The team were polite and respectful, and cleared up at the end of each day with little disruption to our everyday lives. We are very pleased with the conversion and it has been completed to a high standard, thank you Allied Welsh!
Trustworthy and high quality. Allied Welsh delivered on time and budget. Considerate towards the neighbours and nice guys to work with. Would recommend for any loft conversion.
We were delighted with the garage conversion undertaken by Allied Welsh. From the initial cost estimate, the drawing up of plans, to the alterations we made, we were kept up to date with progress reports on what would happen next. All the workforce were polite, friendly and professional and cleaned up at the end of each days work. We would thoroughly recommend Allied Welsh to any prospective customer pondering a garage or loft conversion.
Fantastic company to deal with from start to finish. We had our small terraced attic converted to a bedroom. Work started in December and finished in January. No problems whatsoever, mess cleaned up every day. For such a big job there was minimal disruption to us. The whole team were hardworking and polite. Their standard of work and attention to detail was flawless. We love the new room, we're so glad we a) took the plunge and b) chose Allied Welsh!
The whole team made the process from start to finish so smooth and hassle free. We're really happy with the dormer extension and the work is finished to such a high standard and cleaned up at the end of each day. We have a toddler and everyone was really considerate and friendly which was really helpful and meant we didn't have to worry. Nothing was too much trouble and communication was great throughout. I would highly recommend Allied Welsh!
Amazing firm, quality of the work and the team they had working on our house was outstanding. I would highly recommend them to anyone.
If you are looking to convert your loft, I recommend Allied Welsh. Easy, stress free and hassle free. Any queries were answered straight away and we were consulted before final design if we wanted to make any changes. Communication has been brilliant over the course of the project from initial enquiry to project completion, Really happy with our converted loft and can’t wait to use it after it has been painted.
Amazing service, worked within the budget I had . couldn’t have asked for any more. Had an attic conversion, I already had plans and planning in place that I forwarded on to allied welsh. They suggested to change them slightly, I took a look at the changes and we were very happy , but mentioned that I wish I could’ve kept more space in my main bedroom where I had fitted 4 door wardrobes but was happy to gain a extra room that was going to be a small bedroom which would mean removing one door. They managed to keep my fitted wardrobe and altered them slightly inside to house the new staircase inside and created a new pole in the wardrobe. From start to finish everything was excellent, house was kept clean which I was worried with all the back motor and light carpets throughout , the work men were constantly vacuuming and dusted down the top to bottom through to the hallway and front door when they left and additionally while they worked. Every part of my carpets were covered. Any issues I had I sent a email and received either a call or email immediately and they were resolved. The room turned out better than expected, where I now have a double bed/ office space. They utilised as much of the space as they could and the attic storage space is very easy to access. Everyone was so polite and hard working. I did have issues with my neighbour as he didn’t want to sign the part wall agreement and did try and stop my planning application, I couldn’t get it signed and they spoke to them in person and had it signed. All the carpenters work was fantastic and they matched the doors, door handles and skirting perfectly. Plastering was perfect . They snagged on a regular basis through the work , at the end I checked everything and didn’t find any snags, not one ! Lovey additional storage added under new staircase All in all 10/10 Thank you Allied Welsh
We had a loft conversion done on a 3-bed terrace. From the beginning, we were well informed at every step and we received very detailed plans. We even had the opportunity to choose where to put plug sockets and ceiling lights. There was also the opportunity to consider different types of roof insulation to maximise the internal headroom. Work was carried out every day so the whole job was done in seven weeks (including one week of no work - we were told - when the roofers were on holiday). We really liked this approach as the whole job was done really quickly instead of over several months. The finish was very professional and all, even the small, loose ends were sorted out, including cleaning up after the scaffolding was removed. Quote-wise, above average. But the quote was adhered to with no unexpected extra costs and the total duration was very quick. The only extra cost was choosing a more expensive, slimmer, roof insulation. Highly recommended.
Great team. Great experience. Stress free as everyone highly skilled and competent. Very well organised and efficient - does exactly what they say they will do to the nearest mm!. Finish is precise. Will definately use again. Payment schedule unique and really good, as day 1 everything turns up - all materials and team. No issues of making payments every week. Enjoyed the whole process and pleasure to have the polite team in the house. Awesome- Thankyou everyone
Fantastic loft conversion, guided by Allied Welsh every step of the way. AW built the design around our initial uncertain ideas, advising and supporting us through unfamiliar territory, always willing to listen to changes of plan and to adapt their schedule to fit new requests - often with very little notice. The work team were invariably friendly, polite and highly skilled. They were a pleasure to have around and we cant praise them highly enough.
We’re absolutely delighted with our loft conversion. Allied Welsh were superb. Great design, professional workmanship and everyone we met was courteous, positive and communicative. Having work done on your home is almost no one’s idea of fun, but AW made the process almost painless. We did have slightly cheaper quotes but are so pleased we chose Allied Welsh. We cannot fault them.
Allied Welsh just completed our dormer loft conversion. Overall they did an excellent job without much disruption, considering the scale of works, and with an extremely professional team. The works completed match initial specification and were done to the expected standard. The team was professional, organised, clean, and pleasant to interact with. I am very pleased with their work process and outcome and would recommend to anyone looking to do a loft conversion.
I chose Allied Welsh initially as they quoted less than others I had reached out to. Even with the lower price there was no compromise in quality. The craftsmanship was excellent and they did a really professional job. The build was finished inside the time estimated and they were a really friendly and considerate bunch. Couldn't recommend highly enough
We recently had our loft converted. We have received a professional service throughout. Everything is kept in house meaning the work from start to finish was completed in just over 4 weeks, no waiting around for subcontractors. This was the main reason for choosing Allied Welsh. We would recommend them to anyone 100%
We had a straightforward loft conversion completed in less than 5 weeks, with tradesmen on site everyday. All tradesmen were friendly and reliable, punctual and cleaned up at the end of each day! Professional and efficient service. From planning to completion we were kept in the loop and updated with all arrangements. Could not recommend enough!
Friendly and efficient. We're really pleased with the work. It was completed on time and all our questions were answered quickly. The whole team, on site and in the office, were great. Diolch.
We had a loft conversion with Allied Welsh which they’ve just completed. From start to finish the process was smooth and very easy. The quote was given was reasonable, the drawing up of the plans and getting planning permission was straightforward. We were contacted an offered an earlier start time due to a cancellation. The work took exactly the length of time we were advised. The builders, electricians, plumbers and plasterers were all very polite, punctual and left the house clean at the end of each day. The build quality is great. Not a bad word to say about this firm. Hire them for your work without a second thought.
From the start a great company to deal with. They were organised, on time, efficient and more over all the lads who worked in the job were the friendliest bunch of blokes. A pleasure to have in the house. Very happy with the loft too.
Quality company. I requested a quote for a loft extension in early 2022 as my friend used Allied Welsh and raved about them. I got a call from Dave (their surveyor) quickly and he was in to see my property within a week. He gave me a quote on the day and said - in his cheeky way:- "This quote's stupidly cheap so you'd better accept it before I get shouted at by the boss". He wasn't wrong, as other quote came in about 10-15% more. What I was amazed at is the quote didn't change, they honoured it, even though prices have shot up since then. The process was easy: I had a Harry Potter lookalike and his team come to my house on the first day and they explained what would happen and how it would all work. From start to finish they were all really friendly and great fun to have in the house. I heard reports that they even helped an elderly gentleman who fell over in the street outside, which was nice to hear. Any questions which I had during the process were answered swiftly (even on the weekend) and any issues which I raised (a paving slab got broken on my path about halfway through) were promised to be dealt with. Dean came over at the end and made sure the whole project was finished to perfection. It goes without saying that I would recommend them, I already have and will continue to do so. Thanks to Dave, other Dave, Dean, Hugh and the rest of the team (Paul and Lee at the start) that dealt with the process from start to finish. Excellent.
Allied Welsh successfully completed a complex loft conversion for us during the Summer. The conversion was completed on time, and within the agreed fixed price, to an excellent standard - commented on by friends and neighbours. Communications: we found comms to be first class- professional, respectful and very prompt. All of our concerns were dealt with very promptly and helpfully, and Allied Welsh came across as straightforward and honest. All the design and build team are part of the Allied Welsh permanent staff rather than sub-contractors, so there was a single point of responsibility & accountability for any queries or issues. We also appreciated not having random sub-contractors wandering around our house. Design & Build: we went through a number of iterations from the initial design until we were happy with the proposal and the design team were patient and easy to work with. Build quality and attention to detail were superb- build team worked very hard, were friendly & respectful, and were extremely tidy. It all made for a comparatively stress free building project which was a welcome surprise to us, and we are delighted with the end result. We highly recommend Allied Welsh for these reasons.
We would like to say that dealing with Allied Welsh from start to finish has been the most stress-free experience we have ever had with any builders. The professionalism of all your team has been a credit to your company, nothing has been too much trouble for them even when we have had to make an adjustment here and there. Our property was always left clean and tidy when they left after a day’s work and on the occasions, we were away we had no anxiety leaving the house empty, they simply got on with it. The finished job exceeded our expectations, we would recommend Allied Welsh to anyone without hesitation
We found Allied Welsh to be of the highest quality for all aspects of our loft conversion. They were professional in all depts when dealing with them from the initial quotation work through to the finial installation. The installation team were very respectful around our house and were clean and tidy within minimal disruption to our house and life for 6 weeks. The work they carried out was of the highest standard and we’re always open to questions with regards to the stages of the work being undertaken. The office team were always very quick to respond to questions and when we added additional work they provided quick accurate quotes. The initial quote was very accurate and paid several visits to ensure we understood all aspects of the price against the work involved. There were no hidden costs declared during the build which shows complete integrity which provided us the ability to manage the costs of the build over the project. This is particularly prevelant in this current climate with material costs changing by the week and we paid exactly what we were quoted for several months prior to the start of the work We can’t thank Allied enough and would highly recommend them for aspects of work for house renovation. Mr Williams
An excellent company. We are so pleased with how out attic conversion turned out. Professional, polite and communication was brilliant. Highly recommended!!!!
I can definelty recommend Allied Welsh. They built our loft conversion and were excellent in timing and communicating what would get done and when. They were always available to answer any questions. Every step was great and there was no stress. We are very happy with the end result. Thanks so much Allied Welsh, you have an amazing team.
Never bothered to reply.to.email enquiry
Very happy with the result. Good communication throughout the process, friendly, approachable staff. Given everything that’s gone on in the country (pandemic, supply shortages), it was a really smooth build - well done!
We had our loft completed by Allied Welsh in 2019, we were so so impressed with their work. They were professional, clean, tidy, hardworking and friendly, we couldn’t have asked for more. We love our new bedroom and it was completed to such a high standard, would highly recommend them
We've lived in our house for over 30 years and have used a number of builders for various improvements. Allied Welsh are by far the best of these. Their whole operation was highly professional from design to execution. The various tradesmen that came to our house were very skilled, highly committed to their work and always sympathetic to our needs. They communicated with us regularly to let us know their daily plans. Unlike many builders we have used in the past the team was with us every day, from day one to completion. As a result our loft conversion was completed in good time and very efficiently. We are very pleased with the results. In short, we would recommend Allied Welsh unreservedly.
Everybody who has viewed the conversion has been very complementary about its design and build quality. We are glad that we went with Allied Welsh and I would recommend others follow us. The Installation Director and all of the Allied teams tried very hard to make it easier for us, always answered any concerns that we had and always tidied up at the end of each day. They were always considerate, always polite and friendly to both us and our neighbours, they are real gentlemen.
We have to say the quality, service and communication from Allied Welsh from start to completion has been completely superb.... working within the construction industry myself, I can testify that Allied Welsh deliver to the highest of standards, having several decades of experience, from the initial survey to the really polite & professional site teams who carry out the works (from carefully setting out dust sheets throughout the house at the start of the day, to vacuuming & cleaning up up at the end)..... can’t recommend them highly enough and would not hesitate to use them again, either personally or professionally
Amazing service from start to finish. Works completed to exceptional quality and on time with what felt like an exceptional personal service. We love our double extension and highly recommend.
Completed loft conversion on time, which we are very happy with. Excellent work team, always turned up on time, respectful to other parts of the house and family members, excellent workmanship. I am happy to recommend them.
Having seen previous conversions undertaken by Allied Welsh , we decided to use Allied Welsh for a loft conversion with an en suite bathroom and they were a pleasure to deal with throughout and made the process as painless as possible taking care of every stage from inital consultation , planning applicaiton and on site The quality of the work was superb in every respect and any queries raised were responded to immediately. For the 10 or so weeks that the project took each day they arrived exactly on time and every day left the house in an immaculate state as well and we were always kept informed as to the progress of the works This was an extensive project which I can find no fault with at all. I would highly recommend without reservation
Allied Welsh completed a side-return extension for us. The whole process was very easy, smooth and had great communication. The team were really nice and friendly too. I would highly recommend them.
We are delighted with the work delivered by the Allied Welsh team. They are simply wonderful ! They work hard and have given us an excellent new floor and roof. Their staff are all polite, professional and always tidy up. Big thanks to the whole team for their commitment and top communications from start to finish.
Very nice and helpful staff
We have Allied Welsh do an attic conversion and we still can't speak highly enough about them. All the tradesmen used worked for Allied Welsh and the finish and workmanship was fantastic. Great customer service from the owner who was with us every step of the way
