Mark Smith Plumbing And Heating

The engineer turned up on time, solved the problem in 2 minutes and the company very kindly only invoiced for 30 minutes rather than the normal hour. A very kind gesture that's rare these days but which breeds loyalty.

We might share the same name but that’s where my plumbing skills stop. I have used Mark Smith Plumbing and heating for over 10 years and cannot praise them highly enough. They have replaced a boiler and completed tap replacements and general plumbing work for me without any issues at all. They are quick to respond, very reasonably priced and do quality work - they even remind me when my gas safe certs are due. Easy to deal with and trustworthy.

Been using Mark Smith services for years and couldn't recommend more. Easy system to book services, friendly and informative staff and reasonable prices for all jobs I have had done

Had a very good experience with the team at Mark Smith Plumbing and Heating. Fitted a shower took the bath out and decorated first class job, no mess took everything away. Worked very hard to get it all done for us, thank you

Mark Smith Plumbing installed a water leak detection system efficiently and professionally.

Tustworthy and prompt responses. Had service for very old boiler that was working but service found serious issues . They provided options for replacement. We gave them a key as we were on holiday . New one installed in 3 days . A pipe to a new radiator in the bathroom was a bit cockeye and this was corrected no issue. Greg is specifically responsive and prompt with replies. Their system of job booking with date and time of engineers is efficient and payment is also easy .

Brilliant service, highly recommended.

I have used MSPH service for over a decade , family run businesses with exceptional quality service, I do recommend them for professional and friendly service.

After my outside tap sheared off the wall after moving some bins, the water started gushing out at high pressure, I had to quickly locate and turn off a very stiff stopcock to shut off the water supply to the house. I called for assistance, and Pete and his team arrived within the hour. They immediately identified the issue and efficiently replaced the outside tap along with some pipework under the sink. A few days later, I noticed further leaks under the kitchen – including one around the stopcock (possibly due to it not having been used much before) and another on a separate pipe. Once again, Pete and the team responded promptly, quickly diagnosing the problems and replacing the stopcock, tap under the sink, and additional pipework. All the work was completed to a high standard, at great value, and with excellent customer service throughout. I wouldn’t hesitate to use them again and would highly recommend them for any plumbing needs.

The engineer John was professional and respectful of our home. Will definitely use this company again.

Annual Service, all done efficiently. Changed schedule at last minute to accommodate school run. Still have outstanding pressure loss...possibly a old pipe leak as we have changed everything else...bring on the thermal imaging!

I used this company for boiler check and maintenance a couple of times. On each occasion I was very satisfied with the overall service.

My boiler had it's annual service this morning which was carried out by John from Mark Smith Plumbing & Heating. All well explained and executed professionally and swiftly by John. A very efficient and friendly service and would highly recommend this company for all your plumbing and heating needs.

Mark Smith did a good job helping to cut the gas supply to my gas fireplace and disconnected it as well, friendly and prompt. I will recommend them anytime any day. Thank you

Excellent service, good communication and would definitely recommend.

The engineer, John Crouch, was helpful, neat and tidy and particularly good at explaining everything he was doing. Hope to see you again John, in a year's time!

I was given a quick appointment to change my kitchen tap. The plumber was very courteous and did an excellent job, finishing quickly & even returning my contents to the undersink cupboard. The cist was reasonable too. Thank you Mark Smith plumbing & Heating!

As usual the annual boiler service completed on time and thourally by John

George arrived to refit a radiator in my home and was absolutely fantastic from start to finish. He turned up promptly, was polite throughout, and carried himself with real professionalism. The job was completed quickly, neatly, and with clear attention to detail. It’s refreshing to meet someone who takes such pride in their work. I wouldn’t hesitate to recommend Mark Smith Plumbing and Heating to anyone looking for reliable, high‑quality service.

Greg and his team did a fantastic job for us replacing our old boiler. It was not an easy job as it’s an old house so there were plenty of obstacles along the way. However, the lads got the job done and were efficient, punctual, tidy and kept us informed of what was happening. Greg was amazing at fitting us in at such short notice and Alex did a top job of installing everything. Thanks so much guys. I wouldn’t use anyone for our boiler/heating awesome service!!!

Very good workmanship for an annual gas boiler service and fixing two leaking radiators.

Booked my boiler service on the date I wanted on line. (very good) Service engineer turned up in the planned time slot. He was polite and efficient and informed me exactly what was in the service Update 23 Feb 2026 again a first class service when I requested an engineer visit in an emergency on a very busy Monday the problem was diagnosed and advice given in a few hours. As it happened it turned out to not be the boiler but the gas supply.

Very impressed with professionalism for a job fixing leaky toilet pipe that (if I'd have tried to do it) would have had me cursing at the awkward angles and dropping stuff, and then making things worse.: plumber was really friendly, thorough, explained what he was doing, and made a really good job, and tidied up afterwards. Thank-you very much

Fast, efficient service. Reasonable pricing structure. Very polite well mannered staff. No negatives at all. Thoroughly recommended.

The plumber attended to investigate a kitchen leak that we had been unable to locate. He was courteous, professional, and promptly identified the source of the issue.

Came out same day. Dealt with a leak in my kitchen. Got to the source of the issue very swiftly. Replaced a damaged pipe in a akward tight gap. Polite and professional staff who attended. 5 🌟 service all round. Highly recommend.

great service, came same day and fixed our boiler. Recommend!

The work was done without too much disruption and very little mess. The two guys worked well together. Well done.

Initial repair work was very poor resulting in water damage,subsequent work carried out to rectify poor workmanship and putting things right with water damage was excellent

Engineer arrived on time, was professional and did a good job

I would not hesitate recomending Mark Smith and his son Greg to anyone who needs plumbing / central heating work done. The work is first class and every effort is made to minimise mess and disruption while work is being carried out.

John was very helpful in answering our questions about our boiler, and the service report from Mark Smith arrived promptly the following day.

I had a leaking ball valve in my attic. MarkSmith Plumbing did a great job replacing the valve and the price was very reasonable. They had the part ready in the van and did the repair incredibly quickly. Everyone from the office team to the plumber George who visited were all top notch. MarkSmith are now my #1 call when I need a plumber! Online payments, email confirmations, punctual, top quality and efficient. All round great service.

After a series of bad experiences, Mark Smith's plumbing team were honest about what was needed. They'll be my local plumber now! - great service, reliable, friendly and trust worthy.

Used Mark Smith Plumbing for many years, always reliable, conscientious and polite.

A big thank you to Dhan who serviced my boiler today. Impeccably polite and delivered a very attentive job.

An excellent response to our boiler issue, very competitive costs. Engineer arrived on time and completed the required repairs. Would recommend to family and friends.

Highly recommend this firm, great communication and quality work! They recently refurbished my en-suite bathroom with a new shower, radiator and flooring. My house is quite old (1901) so involved quite a lot of complex pipe work in the project as it was not done correctly previously. Mark came up with the visualisation on how it could look and the final result has exceeded my expectations. The team were reliable, friendly and communicative. Nigel arrived on time and worked solidly throughout the day to get things moving, going above and beyond. Gabor did a great job on the plumping too and everything is working fantastic. Sarah was also a massive help throughout with regular updates on attendance days and also the initial quote. The picture shows the before and after. Thank you so much and I would not hesitate to recommend them.

We have used Mark smith plumbing at our care home a few times now and they have always be reliable very professional and always go above and beyond to get the job done no matter how big or small. Even when we have called them in a emergency situation they have been fantastic and always get us up and running as quickly as possible with as little disruption to the operation in the care home as possible. I must also mention the office side of the operation who are always so friendly and always a pleasure to deal with.

Excellent as always, came on same day I had no hot water and fixed it without any fuss. The plumber they sent,John Crouch, established what the problem was, rectified it explaining what he was doing, very happy customer

Third time I've used Mark and his team. Very pleased with the work done.

Regular customer for letting properties, excellent emergency service and quick response. Also used for general servicing/maintenance/repairs & renewal work, attention to detail is great, as is advice for work required. Many thanks

As always, an excellent Service from the team at Mark Smith Plumbing.

Very pleasant person came to service our boiler. He did a thorough job and fixed a problem we had. Easy to book and pay online.

Had a gas boiler service- very friendly staff, clear explanation of work being done and the staff visiting my home were super aware of cleanliness- removed shoes and kept carpet area clean - would 100% recommend this company and will use them again!

Good service and reliable

Shower fitted quickly and efficiently.

We were very pleased with the work (new bathroom) that Mark Smith did for us. Their advice with design and choice of materials was really helpful. The office staff made themselves available whenever we needed information and responded promptly to our questions. The quotation was clearly set out and reasonable. The tradesmen who worked on the project were thorough, careful and clearly very skilled. They kept us up to speed with what they were doing and were very considerate when it came to the inconveniences of having to turn off the water supply! They were punctual throughout and completed the work in the promised two and a half weeks. Overall, we'd have no reservations in recommending them.

We used Mark Smith Plumbing last year to install our new boiler so we asked them to replace 2 leaking syphon valves in 2 toilets. Despite some difficulties in obtaining the correct parts and the job expanding into a bigger one, we were very pleased with the final result and the final invoice was very acceptable.

Very very good service. Excellent.

Fabulous, friendly & professional service as always from booking the service to the engineer carrying out the work. They started off doing the service on my boiler and then reinstalled a new one 4 yrs ago. They are very reasonably priced on all their work. Myself, family & some friends have used the company for many years now....highly recommend.

Excellent service. Especially considering the very busy time of the year. Thoroughly recommended.

Really quick and efficient service. Great communication from the team when booking and confirming appointment. Will definitely recommend and use again I'm the future .

Quick response, professional engineer and problem resolved without issue

Excellent company. Just wish they priced jobs differently for repeat customers.

Great service. Would recommend for a Boiler service. Easy to book online. Service completed thoroughly and professionally.

Excellent service from start to finish. Communications were very good. The plumber completed the work in a very timely and professional manner. He was also very helpful and pleasant. I have no hesitation in recommending Mark Smith plumbing and will be using them in the future.

Friendly service over the years we have used Mark Smith Plumbing, with added reassurance provided by experts in the field. Reliable and work completed within the time frame specified. Named plumber or Gas engineer. Fully satisfied and would gladly recommend their services!

Speedy response and flushing loo! Excellent!

We always use Mark Smith for our plumbing. They are very helpful when I contact them and always fix things quickly and efficiently. The service engineers are very professional and kind.

Absolutely appalling. Came to commission my system but then said it needed an electrican to sort out some issues. I paid them in full in good faith ... still not sorted after 2 weeks of promises I would be contacted. Be very careful before choosing these people!

Excellent service, professional, friendly, courteous, prompt. Would definitely recommend.

I recently had a plumbing problem coming from my loft. After contacting Mark Smith a plumber arrived the next day to confirm what needed to be done. Three plumbers arrived the next day and replaced my cold water tank which had been leaking. The job was done with little fuss to me and my home was left in a much better state. I am extremely grateful to all involved and consider payment very reasonable. Thankyou Celia Phillips.

We were in dire straights with a broken shower, so a complete replacement was arranged. The work was carried out affordably to a high standard the very next day, and all old parts/materials were removed. An excellent service indeed!

Mark Smith Plumbing has been my go to for many years, most recently they pulled out all the stops to rescue me from no heating and no hot water! On Sunday I realised the boiler wasn’t working, on Monday they diagnosed the fault, on Tuesday they presented my options, calmly dealing with all my questions, and by Wednesday evening I had a replacement boiler, a warm house and hot water! Brilliant service!

Great to see this company going from strength to strength from my first contact some time ago. David on initial call - concerned, responsive and persistent to get an appointment at short notice set up. Then Greg, making it out to the property in good time, diagnosing my problem quickly and giving me multiple options to try and cost save. Exactly what you need and want when a boiler is playing up during winter.

After several false attempts with other firms I was delighted to be given quotations, book appointments which were met and completed by calm ,professional people.

Unfortunately I booked this company to resolve a heating and hot water problem. If I could give them less than one star I would. They didn't have the courtesy to show up for the appointment that I had booked 10 days previously. I had arranged to be at home the whole day for the appointment and they never bothered to inform me that they wouldn't be coming. To make matters worse, that afternoon I called the office to find out where the engineer had got to and they promised to contact James and get back to me. But guess what? They didn't even bother to call back and my later calls just went to the answerphone. They seem to have no respect for their customers or their time. If you're looking for a reliable, professional company I would strongly advise you to look elsewhere!

Ideal Combi installed in the loft. Excellent job done and after care to get the heating setting correct for us. Would recommend every time!

Always friendly staff and knowledgeable.If you need any advise on plumbing and heating Mark Smith is your man, over 55 years experience in the industry.Thoroughly recommended This go ahead company.

Excellent service so professional Mark did an excellent job on our heating system which was very involved, was with us all day exceptionally clean and tidy worker. Would certainly recommend

We have used the services of Mark Smith for a number of years and have always found him to be very reliable and professional. We can thoroughly recommend

I thought that installing new taps in my bathroom might be too small a job, but was pleased when my email request was answered promptly and an appointment was arranged very quickly. The plumber arrived punctually and did the work with no fuss, even though my house has imperial sized pipes and the new taps had metric fittings. He cleaned up and left the bathroom with no mess at all. Brilliant!

High quality service installing a new boiler for us, quick and friendly and did a great job. Mark Smith Plumbing and Heating provided a fast and efficient service. I would certainly recommend them

Mark Smith installed a 7 radiator combination boiler system in December 2018. I have had no problems. Two yearly services by them with very polite helpful service engineers. If I have any plumbing or boiler problems I will definately use this company.

We needed a new boiler and Mark Smith plumbing were excellent at explaining the different options and prices. When they fitted the boiler they were extremely efficient and friendly. They were very tidy and explained to me (very patiently) how to use hive. I would definitely recommend Mark Smith plumbing.

Brilliant!! They installed a new under the bath pump for my shower and bath. Friendly bunch and also came round to check something for me after my fuse switch was switched off by mistake. I highly recommend mark Smith plumbing. I've been in Basingstoke now for about two years....nice one top job!!

Booked a boiler service online. Gentlemen turned up on time, very polite. Gave the advice I needed on our old boiler and completed the service. Will definitely be using this company when we get our boiler replaced next year.

From Start to finish absolutely First Class! Thank you Mark Smith Plumbing and Heating.

So I called this company due to my shower not letting giving me any hot water. The reason I chose this company is because it said it had no call out fees free quote. Someone came out to look at it and I also asked about a new shower. No response after the person went away. I got a call about 6 weeks later asking if I was still interested in a shower and needed it fixed. Thankfully I found another reliable plumber to fix my shower. Now I’m being sent letters to pay £78. No work was carried out and I have an invoice from the other plumber who did do their job and fix my shower and who I paid promptly!. False advertising about no call out charges. Looking forward to seeing this in court.

Very reliable plumbers with reasonable prices
