I'm a regular with HARTSWOOD and Matt, who have recently supplied and fitted a new boiler and also new manifold for the underfloor heating - They are first class, professional, organised, accommodating, and keep you informed - No hesitation in recommending Matt and his team - Mark

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!

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.

As usual excellent service from Hartswood heating would definitely use their services again

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.

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.

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! Positive Responsiveness, Quality, Professionalism, Value Services Heating system repair, Heating system maintenance. More

We urgently required a replacement air source heat pump after being without heating for two weeks. Hartswood swiftly came to our aid. Matt assessed the situation, attempted to obtain spare parts and technical information, but unfortunately, this was not possible. Consequently, we opted for a new system. Matt promptly ordered and had our new heating system delivered within a few days. The service was excellent all around. We enthusiastically recommend Hartswood Heating.

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.

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! Positive Responsiveness, Punctuality, Quality, Value. More

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. Positive Responsiveness, Punctuality, Quality, Professionalism, Value Services Heating system installation. More

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. Positive Responsiveness, Punctuality, Quality, Value. More

New Grant oil boiler finally finished! Started this before lockdown started and only just been able to continue. The customer has new radiators throughout and 2 new hot water cylinders. It's split into two systems, heating and hot water in the main house, and heating and hot water in the annex. All.
