Denver Services Ltd

I would highly recommend Denver Services to anyone looking for a professional heating engineer. They arrived on time and did a great job servicing my boiler and they were a pleasure to deal with.

Professional. Good customer service.

Heating went down in one of my houses. Denver were there the next day and fixed the problem. thank you

Super and efficiant service. New replacement shower fitting installed without any fuss. Will use again.

Always faultless service.

Excellent service. Engineer was prompt, professional and friendly.

An efficient service - and a very reassuring engineer inspecting our boiler! Thank you!

Amazing service. Came within the hour for emergency and sorted out problem quickly

Quality Service, as always

Great service from Denver for my boiler and hot water system. Fast and professional.

We had a number of jobs completed today by Scott from Denver Services . They arrived on time and the work was carried out with minimal disruption and was left clean and tidy. They moved radiators and serviced our boiler and also installed a new button on our toilet system. Highly recommended.

Very professional, highly recommended. New boiler fitted and few months later they installed 2 radiators after we finished re-decoration. They adapted to our needs and gave very useful advice.

We have used Denver several times for boiler services and also a dripping pipe! Their engineers arrive on time and are polite, professional and clear up when they've finished! This time we needed to have our old Aqualisa shower replaced and the workmanship was excellent! Tim took the old shower out and you cannot see the 'join' where the new one is! As is often the case when work is done in our 1930s house there were a couple of unforeseen glitches, but this did not phase Tim who sorted these out very satisfactorily, and we now have a far better shower than the old one! Thank you to Denver and to Tim in particular for his workmanship and problem solving skills! - and also to George who cheerily services our boiler! And not forgetting the lovely helpful admin team, and especially Jo who who has such a friendly and reassuring manner! You can tell this company really cares about the standard of their work and their customer service! We would highly recommend Denver and will continue to use them for any future heating or plumming work!

Very reliable and trustworthy company. George always services my boiler. He is polite , kind, and very professional.Easy to get appointments and the office ladies are very helpful and efficient. Also very competitive price. Definitely 5 star rating .

There was a 24 hour delay from the time originally agreed. This was a bit distressing. Once arrived the technician was very professional.

Had a new boiler fitted with Denver Services. They were helpful, polite and hardworking from quote to installation. I have used them several times before and they have always been highly professional.

We were very happy with the plumber you sent us. He did an excellent job and left our kitchen neat and tidy. We will be using Denver again some time next year to install a boiler.

We’ve always received a reliable expert friendly Service. Extremely competitive. Always available when help is needed.

Prompt, thorough and helpful service by the engineer George. Very good communication from the office. Thank you.

Excellent, Friendly Service, very efficient.

Great service, as always. Fast, reliable would highly recommend.

Good service and new parts fitted on boiler within the agreed time scale. Will use again.

Denver services recently did an annual check on my boiler.Their engineer was courteous and thorough in his checks and I am more than happy to recommend them.

Have had a new boiler fitted by Denver Services in January which was stress free and an excellent service. I have just had my gas fire service as well. All marvellous. My gas fire was serviced recently. Excellent service as usual. George noticed my carbon monoxide alarm was out of date after having had a fire check by the Fire Services!

A competitive quote and the work carried out efficiently and without fuss. Aaron ensured no mess was made and used protective sheets. Good job all round.

A really courteous service as usual from Denver Services - thorough and helpful. No hesitation in recommending.

Recently had our combi boiler serviced by George from Denver Services. He arrived on time, polite and respectful. Identified and rectified a problem we were unaware of that could have proved costly in the future. Thanks George.

Had a leaking radiator which was replaced. All good

Highly recommend Denver Services. Always reliable, with fantastic engineers and customer service.

Prompt clean and tidy ...new boiler installation. Highly recommended.

We recently had Denver Services carry out the annual service on our gas boiler. The service engineer arrived in the booked appointment time and the service was completed along with the service record updated in a timely manner. The engineer was friendly and professional.

I had to manage work in the uk from Cyprus. The work was carried out as agreed. Fantastic service.

Well done job. Danny the fitter came on the arranged day and did a really good job. Kept fully informed and cleaned up every day. Would use again.

A wonderful company -kind and efficient --Tim and George have done work at my home and are great! Highly recommended.

Prompt, efficient and effective service

Friendly and attentive staff. Job assessed and carried out quickly and cleanly

What a lovely company. You hear so many stories these days, but I can truly recommend Denver. I now live on my own and not used to dealing with boiler services and the likes, but Tim my engineer explained fully what he was doing, answered all my questions and advised me on what I should be doing and when. He was very knowledgeable and made it all very clear. The work was carried out well, engineer wore overshoes which I thought was very considerate and left my house all clean and tidy. Would highly recommend them and will be using them in the future. The work I had done was Boiler Service, radiator flushing and I had to have 3 radiator controls replaced as they were not working.

Arrived on set day and on time providing a very quick and efficient service.

We have just had a beautiful shower room completed by Denver Services and could not be more pleased. The quality of the tradesmen Denver use is second to none and we would highly recommend.

From quotation to installation, the process of replacing my aged boiler was seamless. Aaron at quotation stage and Danny at installation stage were both very professional and knowledgeable. Would highly recommend Denver Services. Thank you.

I had my regular boiler check with Denver and as usual the service from the engineer was outstanding. He was on time, very professional and explained everything he needed to do to complete the check. He was polite and left the utility room tidy and everything returned to its place once he was finished. Denver is a great all round organisation from contact to book an appointment with the office to the completion of the boiler servicing. I cannot recommend them highly enough. I have always been very impressed with the staff as they have been outstanding and consistently efficient. They team always go the extra mile.

A major upgrade to our water system involving taking out the old water tank and installing a new combi boiler and shower was carried out to our complete satisfaction. Danny respected our house leaving it in a clean and tidy condition. Would definitely recommend.

Problems with a communal water pump house. Someone removed a pump and left us with bare 3Phase wire tails and leaking water in there. Denver attended site promptly and again with the pump supplier to verify the details. Actual remedial works completed in two hours. Very satisfied with these guys. They know what they are doing and do it with a smile.

Yet again Denver Services have provided an excellent level of service, in a prompt and efficient manner. This was for our new boilers annual service, previously we had been with British Gas who have completely lost what customer service means. We'd not hesitate to recommend their business.

Called Denver Services when our domestic hot water decided it didn’t want to work. Right on top of Easter, they sent George same day to diagnose problem. Four days of Easter Holiday came and went. We accepted the quote on the Tuesday and a date arranged, George came back and put all to rights. We know George as he comes annually to service our boiler. We are always very satisfied with this company and the excellent service we receive.

Use with caution (and always check your invoice).

Excellent service from Denver, supplying and installing a new gas central heating boiler and at a fair price.

Fantastic. Hard working. Diligent. Listened and installed accordingly.

I previously had a good experience with Denver Service for an annual boiler check — the engineer was on time, polite, and friendly. However, my recent plumbing experience was disappointing. The plumber didn’t show up during the scheduled time, and when I called, I was told he was just “a little behind.” No one came or called back. The next day, they cancelled again without apology, saying they’d call next week. I lost time, missed work, and felt frustrated by the unprofessional and unfriendly phone communication. Denver Service needs to improve time management and staff training.

Great service. Reliable, always on time and good communication, on email and on the phone.

Had quite a bit of work done by these. Upgraded system, new boiler, extra radiators, new tanks, new emersion, they service us annually. Recently came out for a radiator problem that grandkids nearly pulled off the wall. Excellent service always reliable, clean and fair pricing. Highly recommended.

Yesterday it was George's turn. He did a great job , very professional and very knowledgeable. Heat Pumps are not everyone's "cup of tea" but no issue for George. Its now supercharged, shining and purring like a... Thanks very much. About 18 months ago....Matt did the job with skill, perseverance and good humour. I have had several excellent encounters with Denver and they have exceeded my expectations every time.

Work quoted for on 26/01, quote accepted on 30/01, work (of a minor nature) completed on 21/02. Work completed to our satisfaction by Tim who clearly knew what he was doing. Whole experience was not only painless but very reassuring. Very happy. Many thanks indeed.

Excellent service, friendly and helpful staff would recommend to anyone.

We have been working with Denver for a couple of months now, and we are very satisfied with the working relationship we have built in a short space of time. We are pleased with the customer service provided and they have adapted well to using our platform Symple.

Excellent service. Prompt reply to enquiry. Showed up on time, completed the work, left no mess.

New Worcester Bosch greenstar boiler

Always Reliable and fair priced.

After using Denver for several years for boiler servicing , we felt very confident to have a boiler replacement carried out by them . The quote was competitive and acceptable , and all appointments happened on time . Very happy with Matt who did the work for us, a very pleasant guy, who showed respect for our property and cleared everything away beautifully,

Our experience of using Denver Services to upgrade our heating controls was brilliant from start to finish. We received the quote soon after the initial visit and the work was booked in and completed to our total satisfaction very soon after. Adam clearly explained how the new system works and was very helpful when answering all our questions. We would highly recommend them and will not hesitate to use them again in the future.

Have used Denver for years and also for my elderly mother and always trouble free…very helpful and never feel like you’re being ripped off.

Very pleasant company to deal with. Great engineers, prompt, clean and efficient. Helpful advice given. We'd had our previous engineer for many years and Denver took over his customers when he retired, always a worry when you have to use a new company but the reviews are superb and I'm pleased to be able to add to them! UPDATED July2024 - excellent service again, very pleased! UPDATED Feb2025 - excellent service again, quick clean and efficient. Thanks!

Arrived early so that's good. Explained the problem to me so that I can understand! Quickly sorted.

Reliable and professional service

Excellent customer service from enquiry to works completion - Aaron the MD then Matt and Tim operatives were very professional in their smart Denver black &!gold livery vans and jackets - super communications through the process - will definitely use again and recommend to colleagues.

Great service from the team at Denver - recently serviced my boiler and fitted a new tap, friendly, prompt and thorough!

An emergency call out to fix a leak from a failed water pipe was promptly dealt with. Office staff were able to send Scott to make the system safe, and rearrange schedules so that Adam could attend a few days later to replace the pipework and restore the hot and cold water. Office staff and engineers were very friendly, polite and both Scott and Adam arrived on time, and were very efficient and professional. I would recommend Denver Services.

The technician was very friendly, and did a good job. I can fully recommend Denver Services.

Excellent. Such a professional service. Engineer explained his results and was happy to answer my questions. Without doubt. Excellent. Thankyou.

Came to view job arrived on time quote accepted plumber arrived 10 mins early must be a first job done no fuss bit unusual by today’s standards VERY HAPPY

I was very pleased with the Magna Cleanse. Tim the heating engineer knew what he was doing. I was amazed how much gunge there was in our radiators. Now all our rads are hot within 10 mins. And they are all hot, before one was hot others not so hot and one like warm. Wish I had done it before, before we used to pray for a mild winter !. Would recommend getting it done. Will definitely use Denver again.

Denver Services are reliable and I am very happy with the recent boiler service they provided. Very quick and efficient. Also checked my radiators and advised on how to maintain the system.

Denver services recently carried out plumbing work for us, we're very happy with the quality of the work and their pricing is fair. It was all efficiently quoted for and organised, plus all their staff are pleasant and easy to have working in the house. We have used them numerous of times for servicing and plumbing work and would happily recommend them.

I had my Ariston electric boiler serviced, it was working perfectly prior to the service but stopped working within an hour of the service. The engineer came back the following evening and got it going but again it stopped working the next day. The office said they would send someone around to check and change a spur but there has been no follow up. It has now been two days without hot water. I would expect putting this right would be a priority

Denver a professional friendly helpful group of people

Really great service from Denver Services who fitted my new boiler and returned for its second service there were no problems with the boiler as expected. Great communication, organised, friendly, professional, and helpful staff from the engineers to the office staff. See you next year for service thank you

Therefore, it is important that I can rely on who I employ to turn up on the day/time agreed, be trustworthy and carry out the works to a good standard. Denver Services meet those criteria. My tenant also speaks highly of them. Peter

They replaced our boiler on one of the coldest days of the year but sent two engineers so that it would up and running the same day. I would highly recommend them.

Timely and friendly - good customer service and got me up a running quickly when my boiler needed replacing.

I was recommended Denver Services, by one of my neighbours. They initially came round to do a service on our boiler, which we have had for many years. We knew the boiler was extremely old and I asked Denver Services for a quotation for a new boiler and to replace the ancillary equipment related to the heating and hot water. A quotation was provided which was satisfactory and they were booked in accordingly. The engineer arrived on site on time with all the correct equipment and basically cracked on with the job. Extremely polite, extremely professional and he certainly knew what he was doing. The system upon installation was fully tested with everything working satisfactorily. After everything was cleared up, and all the old equipment and packaging taken away, he showed me how the timer system worked and that was all set up and configured correctly, has been perfect ever since. I just wish we did this five + years ago. Great job done and I can comfortably recommend Denver Services.

Came on time; did the job efficiently,without mess or drama!

Efficient service, nice to have a friendly admin lady on the end of the phone, and what’s app photo showing the problem and speeding up the repair process

We have used Denver Services for at least 20 years to supply, install and maintain our gas and plumbing equipment - visiting as recently as last week - and always found them to be knowledgable, extremely efficient, trustworthy, and very reasonably-priced. They always treat the property with the utmost respect and leave it spotless, yesterday included. The sort of people it is a pleasure to have in your home - even if you are not able to be present.

Proffesional operation

Had our thirty-two year old boiler replaced by Danny from Denver Services. Danny did an excellent job, which turned out to be quite challenging. He explained what he had done and left our kitchen clean and tidy. Would definitely recommend Denver Services.

George from Denver was very professional and took time to help identify why our boiler may be dropping pressure. Very pleased thank you

Excellent communications. Always answers phone. Prompt service. Excellent plumber. Good rates. Would highly recommend

Great service. Rang on Weds and had the service done on Friday. Happy with everything

Had my boiler serviced on 31st March and was very impressed that the Hoover was used to clean out a lot of debris. My previous service contractor had never done that before. Service person very pleasant and service completed satisfactorily. Local company that I will use again.

Although it took a few visits to determine exactly what was wrong, Denver technicians were polite and helpful throughout, keeping us informed about progress and potential solutions. It seems manufacturer (Vaillant) advice on telephone helplines was initially misleading. The replacement part eventually identified was somewhat less expensive and was reflected in the invoice being a little lower than the estimate. Highly recommended service.

Had an issue with my CH, they came out same day inspected it and returned with part the next day...fixed !

Very professional and reliable service.

A very good service from Denver Services when fitting a boiler. Professional, friendly and tidy so highly recommended.

Great professional company. Boiler installed by Matthew. Always advised on what was going on. Clean tidy. Didn't leave until heating was fully operational. Firmly recommend

Very fast response to my call for help (next working day) And an engineer who seemed to know exactly what he was doing. Went straight to the real problem despite my erroneous assumptions about what was wrong. Couldn't ask for more.

Great service with friendly staff

We had been previously recommended to Denver Service and had used them in the past for boiler servicing. When our boiler broke down recently we called them in to see if it could be fixed but as parts are unfortunately no longer available we were told we needed a replacement. Didn't hesitate to use Denver and a new boiler was installed within a few days. Danny was extremely efficient, very tidy, very personable and the installation didn't take as long as we expected. Wouldn't hesitate to recommend.

Can't recommend enough. Great service from office staff, and prompt service from friendly experienced and skillful plumber. Very happy with the service. Would recommend to all.

We cannot fault the service from Denver. We were looking to replace a boiler with a Worcester Bosch and detailed on their website were a number of approved installers. Once selected they were quick to contact us, visit our property, provide a competitive quote and then install the boiler. They have been efficient and professional from the outset.

Excellent service as always. Trustworthy and reliable. We highly recommend.

Denver engineer identified our central heating problem and repaired it promptly. Excellent service.

Great customer service, turned up on time and did a great job. highly recommend

Very impressed with the service and the thoughtfulness of Olivia to keep us updated and generally informed. James who installed the boiler was on time, efficient, friendly and cleared up afterwards. Couldn't recommend them highly enough.

Great service with great helpful staff . Will definately use again

First time good experience. Polite helpful people and would recommend

Matthew was helpful and polite, taking his shoes off at the door. He explained what he was going to do and got on with it! Nice chap. Look forward to seeing him next year for the next service.

Excellent Service - Professional Engineer done a great job on servicing my boiler and a very reasonable price. Will definitely use Denver Services again.

Darren from Denver has just done some work on our heating system. Service from hi. And the company is excellent

Efficient, professional, friendly. A pleasure to have Danny in our home.

We used this company to service our boiler. There service was great as was their communication. Wouldn't hesitate to recommend or use them again.

We recently had a new gas boiler installed by Denver Services. The fitter arrived on time, did a neat job and left the house in good order. We will use Denver Services in the future.

We experienced a number of local plumbers not returning our calls for a quote or they were not interested in the job - to replace a shower and fit new bath taps! Denver Services came to our rescue totally efficient and reliable from start to finish! Can highly recommend this company.

Always, friendly and efficient service. Highly relaible too

Small job but turned up on time and done quickly. Identified the parts needed, unlike another plumber.

efficient and quick appointment, would recommend

Regularly use, cheap and efficient service. Would recommend

Excellent service provided where British Gas failed. Denver Services quoted our landlord for a new boiler after 6 missed appointments from BG and Denver's turned up, quoted and fitted the boiler today. 3 very happy children having a nice hot bath tonight after 2 months of sporadic hot water. Thank you! 😊

Not one start, zero star. Waited two weeks for a repairman who didn't appear to know much about boilers. He refused to repair it, failed to show any of the horrors that he was gesticulating at. (I'm an engineer so I can tell the difference between some dirt or stains and obvious burn damage.) It looks pretty clear that it was all a con for Denver to send sell more new boilers to people that already had a perfectly good one already installed.

Very friendly engineers. Understand fully the concept of Customer service and I've found them very reliable. Would definitely recommend and will use again without doubt.

Always reliable and friendly, very knowledgeable, highly recommend.

Great service as always from Denver Services. Their communication and organisation is second to none. Would highly recommend.

I can categorically say that Denver Services are a first class service. From the moment I phoned them with regards to our faulty boiler and the new one installed by engineer Paul, it was smooth sailing all the way. I would definitely recommend!

This was the first time of using Denver Services which was for a small plumbing repair, but they will now be my preferred contractor for any plumbing services. Polite & professional service from the time of making the appointment through to the work being carried out. Excellent service and value for money. Highly recommend.

Our heating system stopped working. Called Denver Heating Services who organised a visit the next day and were able to replace our valve at the same time. Always efficient, reliable, and were Covid 19 compliant. Even wore shoe covers! Would recommend.

Nice smooth efficient radiator install.

After boiler packed up on a Saturday Morning we expected to wait after the weekend but Aaron found time to come round same day to check and by Thursday new one was fitted. Great service. Thanks !

Professional friendly service. Appointment made with ease to service my boiler. Paul arrived on time following all the covid regulations. Explained what had been carried out. Aaron fitted my new bathroom a couple of years ago and was always available to answer any questions, deal with any problems even popping out to show me how to do a minor procedure on my hot water tank.

Speedy and reasonably priced turnaround on a replacement boiler and thermostat - good communication too! Much appreciated !

What a fantastic service! The engineers were on time, polite, extremely professional and did a wonderful job. They tidied everything as they went and I cannot recommend this company more highly.

Pete is a very pleasant man, so professional, on time and did a great job. Would not hesitate to recommend Denver Services. Eileen Crawley
