Hartswood Heating Ltd is described by customers as friendly, professional and helpful, with many reviewers saying they have used the firm for years for boiler servicing, repairs and installations. Several reviewers praise the firm's communication, including being kept informed and told when engineers will arrive. Heat pump work is also reported positively, including installations and servicing, and one reviewer says Matt explained how their system worked and made videos for them. A single reviewer reports very bad service and says the firm did not answer, and another says they would have preferred a slightly lower bill, though they accepted the estimate beforehand.
Long-term client, boiler needed replacing. Excellent service and quality. Thank you.
Excellent service from start to finish. Would happily recommend Matt and his team of engineers to anyone.
Hartswood Heating are always helpful, friendly and efficient.
Outstanding service from Hartswood Heating. The team was professional at every stage, from booking through to the work carried out. I would highly recommend them.
We've used Hartswood's on numerous projects now, from heat pump installs to full plant room installations on listed buildings. Can't fault their work they really make an art of plumbing. Couldn't recommend them enough!
Very good service as usual, arrived on time and very professional engineer.I have used them for the last 3years to check out our LPG boiler ready for winter. Will use them gain next year well done team.
I have used Hartswood Heating for years so I can only say good things about them

I have used Hartswood Heating for many years. They are always reliable and provide an excellent service. Would highly recommend.
Had our boiler serviced by Hartswood heating today, they came on time, great communication, no messing about, came in did a professional job. Very reasonably priced. Thank you for prividing a great service. I would recommend
Not local to me but worth the wait to see Matt. Although competent in all things heat pump related, he was still happy to learn from the Samsung experts. They sorted out a simple and pragmatic solution to the problem of getting the heat pump to work in reverse. The kitchen was 10 degrees cooler than the 35c heatwave, making it bearable to work and rest. Thank you Matt
I have had an end to end positive experience with this firm. They installed my ASHP last year and serviced it this year.
Hartswood Heating - have been great though out the installation of all services in our workshop. Great communicators, efficient, knowledgable & friendly. I would thoroughly recommend professionally.
I can honestly say these guys are brilliant. Absolutely zero fuss and zero stress. The work gets done with total transparency and top level workmanship from start to finish. Hartswood did my air source head pump and just recently my air-con installation. Faultless.
Matt and the team did a fantastic job. They worked with us and were flexible and the team were really friendly and explained everything. Heat pump is a huge decision and you want to do it with people you trust. Go with these guys.
Work done well and efficiently. Highly recommended
Highly recommend from Vicky in admin to Matt as an engineer absolutely perfect. Thank you so much . I will be recommending if anyone needs your expertise. So polite on the job, got it sorted nothing was too much. Thank you
Matt is great, always so helpful. Thanks.
Matt comes to service our boiler yearly and does a great job, he’s very thorough and professional and very knowledgeable. He’s also done other heating work for us with our underfloor heating and we were extremely happy I would highly recommend him very trustworthy Extremely happy with Matt and the service he offers he fixed our underfloor heating issue without any issues and where others couldn’t, he’s kind, patient and friendly and that’s good when you are nervous who comes to the house - highly recommended thank you
Superb all round!! Happily recommend & will be using them going forwards. Charlie was excellent & fixed the leak in my boiler.
Great service, nice people. Can't ask for more :D
Such a positive experience. Genuine honest people. I was really impressed with being kept up to date and informed and never having to chase. The work was second to none, and they were so accommodating to my situation. Can't rate them enough. New local favourites that I will be telling all my friends and family about.
Excellent service - both Matt & Sam visited our property to diagnose & then repair our boiler - they were both friendly & professional and got our boiler back up & running. We will definitely use them again and can highly recommend.
We had our boiler serviced by Matt this morning. He was very knowledgeable, pleasant and very efficient. I would have no hesitation in recommending Matt.
They have always manage to get going whatever has failed, so I am very happy with their service.
Excellent installation and post-installation service from Hartswood Heating. Friendly, efficient and helpful, Matt also provides advice on possible future savings on energy costs. We are very happy with our air source heat pump and would heartily recommend Hartswood Heating.
Charlie was very friendly and professional, I would highly recommend Hartswood Heating Ltd to install a new boiler or service your boiler.
Hartswood Heating replaced my air source heat pump. Absolutely fantastic service from the onsite installation team and the back office. Highly recommend this company. Thanks and well done!
My ancient boiler failed spectacularly on 29.12.25, leaving me with no heating during the coldest weather this year. My neighbour recommended Hartswood Heating Ltd who kindly managed to take an engineer off another job and start to instal a new Vaillant boiler. It took two days and I am delighted with the result. Hartswood Heating's quotation was lower than the two other quotations I sought. I feel in very safe hands.
Hartswood are excellent,skilled professionals who always do a great job and on top are easy and personable to commincate with
Incredibly prompt, pleasant and knowledgeable. Serviced our boiler and resolved a pressure issue. Would use again for sure.
Very helpful engineer who serviced our cylinder tank and checked water temperature and flow, and advised on possible reasons for underfloor heating not fully working in one upstairs room. Have asked for further advice on fitting a pump to increase water pressure to upstairs showers. Will most certainly use this company again now that I have found it.
Superb service Thoroughly recommend.
Always an amazing professional servise
Excellent service detailed in full and photos included highly recommended
Excellent service, communication and would highly recommend. Vicky, in the office is wonderful. Matt and his engineers are first class and their prices are very good too. So pleased to have found them.
Great service and really friendly!
A couple of days ago Hartswood Heating sent out a plumber to sort out problems with old under-sink pipe work in my kitchen which had come to light after a boiler leak recently. After a courtesy text Charlie arrived within the time frame I was given and sorted out the problem by cleaning out old pipes as well as fixing up new ones to create a better flow. He explained all the steps, got skillfully on with the job, tested at the end and left everything clean and tidy. He is a friendly and competent plumber to have around and I am very pleased with the job. Although I had wished for a slightly lower bill (I had accepted the estimate beforehand) I'm very happy to have found a reliable company which I will certainly use again in the future and which I can happily recommend!
Absolutely amazing work as they installed Column radiators in my house. Would highly recommend & thank you again
Professional and prompt service
Such a professional but also friendly company, fitted our gas central heating system a couple of years ago, recently carried out a service on the boiler, all the staff we have dealt with have been really good, informative and helpful. Thank you
Very friendly and professional team. Serviced our ASHP very promptly and went the extra mile in explaining things to us
Great service from Charlie today who serviced our boiler. Highly recommend this company.
excellent service . thank you
My yearly boiler service has been done by Hartswood Heating for many years and I can thoroughly recommend their work.
Quick and efficient service , would definitely use again .
Used for servicing of our ASHP. Very efficient communication and extremely impressed with their knowledge. There are a lot of people who say they do but don’t know much about ASHP. These guys are the real deal
Had my annual service for my central heating boiler in September. Timely appointment, and Charlie carried out a good professional job to service my Worcester Boiler.
Great firm of plumbers. They're always super helpful and quick to come if you have a real crisis!
Matt and Sean Chapman of Hartswood Heating provided and installed my Vaillant gas boiler in 2022. Since then I have not had any issues. This year (2025) Charlie H.(Happy Birthday) performed the annual maintenance/service - very clean and organised technician. Contact Matt at Hartswood Heating with your boiler and plumbing issues.
Incredibly professional and reliable service as always.
Very good 👍 Came when expected and notified before they arrived. Polite and efficient service. 😁
Excellent company and a very skilled mechanic who resolved our problem in an exemplary manner. I have no hesitation in recommending this company for all such work
Fantastic service received, we woke to find we were gradually loosing water, this was a Friday morning and I was worried we may loose all water completely. Vicky from Hartswood managed to get one of her plumbers out to us that afternoon. Many thanks you are all amazing 👏
Great company. Boiler serviced promptly.
Team are fantastic, prompt and were able to do a service in a very quick fashion. Highly recommend
Super service, accurate diagnosis and repair of a long-standing issue. We’re delighted!
It isn't easy to find an air source heat pump engineer and when you do there is an element of nervousness around their competence. No such worries here. Matt is fantastic. I would have absolutely no hesitation in recommending Hartsweed Heating.
Great attention to detail and pleasant company
Matt and the team were excellent. Very professional from start to finish. Nothing was too much trouble and made the whole experience an enjoyable one. Very highly recommended.
Excellent, friendly service! Will use again.
Matt installed our air source heat pump, and does its annual service. He is knowledgeable, professional and always helpful and friendly- highly recommended!
Great service from Hartswood Heating. I booked a boiler service and Gas safety check by phone. Everything was straightforward and Vicky was really helpful. The work was completed on time and paperwork followed immediately. Very reasonable price, I'm a happy customer!
Great service and Matt is a pleasure to deal with. Use them!
Excellent service from Matt to quickly repair heating system during a very cold spell.
Charlie from Hartswood Heating came to service the boiler as I have just moved into a new property where there was no paperwork or gas safe certificate. He did a thorough job and spent time answering my questions as well as recommending future actions on my part to ensure the smooth running of my appliances.Thoroughly recommend.
Matt was brilliant, very knowledgable and helpful. We bought a property with an air source heat pump and had minimal knowledge on the system. Matt showed us exactly how it worked, and even created videos for us to play back. We will definitely be using him again for the annual service.
Excellent communication and customer service. Would highly recommend.
Boiler Technician arrived on time, serviced our boiler, and explained in detail what he'd done. Completely satisfied. Good price too!! Thanks!!
Matt is extremely efficient, thorough and knowledgeable.
Booked a visit online (nice to have that as an option). Matt arrived promptly and completed the service quickly and efficiently. Will use again.
Really good attention to detail. Service for our ASHP system
Our old plumber moved on and we were recommended these guys. What a recommendation! Really great service from first point of contact - quick to respond and got us booked in nice and quickly. Charlie - who did the job - boiler service - was brilliant - informative, friendly and gave helpful advice about a possible leak. Couldn't recommend enough - will definitely use again!
Hartswood Heating have done lots of work for me and have always given me excellent service. I unhesitatingly recommend them.
Reliable, friendly and customer focused service from all the team.
I’ve used Hartswood Heating a number of times. I am always happy with both the workmanship, efficiency, and professionalism. I would highly recommend.
Matt's team installed a new scheduling system for our heating and some new radiators. They worked really hard and efficiently, and left everything tidy. Matt recommended a Honeywell evohome system which is easy to set up and seems to be working as expected.
Excellent - Matt did a thorough and efficient boiler service and even got our dripping tap sorted. Always a friendly and trusted service.
Mat came to service our combi boiler. He was quick and efficient. He also was able to answer some questions we had regarding the thermostat and noise from the heating system. Fully recommend Hartswood Heating!
Very bad service They not answer Just stay away
Hartswood Heating are fantastic! Their communication is brilliant. We were always kept informed about visits and arrival times etc and they discussed the work they were doing on site so no surprises. Matt, who attended to our heating, is also a lovely man and extremely committed to doing a first rate job at a very competitive rate. I can recommend Hartswood Heating without reservation.
The work proved to not be straight forward but Matt was persitant and returned to ensure that every thing was completed safely and to high standard. He explained everything he was doing and why.
Matt and his team provide a fantastic service - they go the extra mile to ensure that everything is taken care of, their rates are reasonable, they are extremely knowledgeable and always kind and friendly. Highly recommend!
As usual excellent service from Hartswood heating would definitely use their services again
The engineer was informative and professional. He did a thorough job of servicing the boiler, informing me throughout about what had been done, and why. I would recommend Hartwood Heating to anyone.
They installed a new boiler this time last year and It's just had it 1st service, no problems at all and all running fine, based on our experience we would recommend them. 24th April 2024 - Boiler serviced, efficient and professional as always.
Exceptional heat pump design & installation from start to finish. Matt and his team designed and built an air source heat pump powered central heating and hot water system for our house from scratch that only had storage heaters and an immersion heated water tank. The design was on point, flexibly designed for future planned improvements (an extension) and also at a very fair and competitive, transparent price that he stuck to. Matt also took the time to explain everything in what is an emerging technology that was new to us and answer every question we had. The work was done very neatly and considerately, the pipework is neatly laid out - routed to ensure we can extend with minimal troubles and the disruption was minimal considering every room needed pipework running to it. Matt was also very responsive and has been on hand to fine tune and he and his team were meticulous in snagging and cleaning up. I'd recommend Matt to anyone in a heartbeat and would be happy to talk to anyone considering his services to give more details. I very much feel like we lucked out finding him.
Sorted out a problem radiator and installed a Drayton Wiser HubR (the key part of a smart heating system) for us. In the process, did the best bit of investigation work I have seen from any heating professional so far, and replaced a mess of existing wiring with a tidy, organised, labelled, professional installation, all at reasonable price. Very pleased.
Second time I've used Matt and his team. Will do so again. Professional, knowledgable and trustworthy.
Matt was so helpful in explaining some of the intricacies of our ASHP and heating system. He and his colleague were very efficient, knowledgeable and friendly and I would highly recommend using them. This is the second time I’ve used Matt. The first time he came out for an emergency when we had a problem and the weather was cold. He fixed it straight away.
Again first class service. Required a new circuit board, I was kept informed through the full process. Thank you Matt,
Always first class.
Very happy with the service
Completely satisfied with our first experience of Hartswood Heating carrying out our Boiler Service. We particularly appreciated the detailed report and the 'alerts' regarding actions to be taken next year.
Very professional and tidy. Highly recommend
Engineer was professional, friendly and thorough. Took his shoes off at the door, which I thought was a nice touch. Will use again and recommend to family and friends.
The best heating engineers we have worked with. Knowledgeable, prompt, they do excellent quality work and always give an honest opinion. I would not call in anyone else.
Great experience on a heat pump installation.
Hartswood came highly recommended and fully deserve their 5 stars. Diagnosed the problem, communicated all the way through the process and arranged for the supply and install of a new gas meter. I would not hesitate in recommending them!
Incredible service from Matt. He was very generous with his time when discussing our central heating requirements in person, by phone and by email and was able to give a number of quotes, booking availability in his calendar to meet our needs. We were looking for an air source heat pump but when our requirements changed after he had met with us he was quickly able to send us a new quote for a combi boiler, even letting us know that a cancellation had opened up the same day to get an urgent job sorted for us before the main work would take place.
Absolutely fantastic service from the guys at Hartswood Heating. Top quality workmanship in every aspect. I even got given a free Hartswood Heating reusable travel coffee cup. Just brilliant. Matt is good looking guy too.
Excellence professional and friendly service Matt sorted out an urgent plumbing problem and it was 8 pm.... Also recommend Matt for new Boilers and complete new Heating Systems. Honest advice and a fair price for quality workmanship.... Craig Elford
I wouldn't use anyone else - clean work, knows exactly what they are doing, and even found some things that weren't put right from our previous engineer! And, you can book your boiler service on line - how easy is that!
Fitted a new boiler in our flat as well as new radiators and a smart thermostat. Very organised and did a very neat and tidy job with the pipe work. Great professional attitude and would thoroughly recommend and use again.
First class services. I needed help sorting out a heating system on a property in Sussex and after speaking to a few different companies and getting nowhere I contacted Matt at Hartswood Heating. Matt is a very knowledgeable and helpful guy with lots of experience. After getting a very good broken down estimate from him with a guideline start date we booked him in and was pleasantly surprised on how tidy there work is and how professional they are. I'm the owner of a building company now based in Sussex and use Matt and his team for all the boiler installations, heating systems and repairs. I would highly recommend you use Hartswood Heating and will be using them again on future projects.
I booked a boiler service online. Great service, prompt and friendly. Will use again! Thank you!
