Thermofix Services Ltd Reviews 

What a great team! Thermofix did a terrific job in installing my air source heat pump. It was not an easy installation as they had to deal with an old, badly installed central heating system. However they found solutions to all the obstacles they encountered. They linked the system to my solar panels, giving me one of the most energy-efficient systems on the market. Thank you!

Steve and his team at Thermofix were fantastic. They are super busy but managed to fit us in earlier than their original date.

They gave us lots of useful advice and did a super neat job at our house. They were very thorough, helpful and gave us advice to get best boiler for our needs.

He went above and beyond for us - thank you!

From the start this company reacted quickly to the loss of heating and arrived on time. Carried out the work professionally and were just so efficient. Definitely use again and would recommend to family and friends

From the initial visit, clear communication and quoting I was impressed by the service. The day came for the boiler install, they arrived on time and wasted no time getting started and worked hard through the day. Friendly, polite, clean and tidy. They got the job done and we're so pleased with our new boiler. Thank you Thermofix!

Thermofix installed, and have maintained the boiler at my sons house. Each time i have called, they have responded quickly. A leaking radiator was quickly and efficiently repaired (not fitted by them, but due to a leak). They capped of a gas hob, excellent communication, everything very efficient. would highly recommend

Thermofix are a great company with really helpful guys.
I've been using them for a number of years in connection with my property business, and they always do a great job. They are willing to talk through possible solutions, and I always feel that their prices are fair. Genuinely a pleasure to deal with!

Really friendly and knowledgeable guys. Excellent communication and no nonsense. Finished the job on time and with no surprises. Probably the tidiest people to do work on my house too! Will certainly recommend to others and ask them to work on future projects.

Very professional, courteous, friendly and efficient.
Would definitely recommend them to anyone looking to upgrade their heating system.

Thermofix installed our central hearing many years ago and continued returning for services / upgrades. Brilliant team. We were a little nervous about adding Solar/Battery/Mixergy tank, but it is an excellent decision. Mixergy is extremely efficient and the app offers a good deal of flexibility and control. We will make significant savings. The installation was very well
managed.

Efficient, timely, clean and tidy. Couldn't fault the service received.

Always prompt, polite and efficient. Honest with his advice about boiler maintenance.

Gareth and Thermofix were recommended to me by a plumber friend. Gareth was extremely efficient in replying to my initial contact. He arrived on time and carried out service and additional work with agreat deal of professionalism, efficiency and in a very amiable manner.
He helped with advice with regards to Hive installation and we are very pleased with the new Hive thermostat..
I would recommend Thermofix without reservation..excellent service...thanks

Were recommended Thermofix by a family friend and am extremely happy with everything.
Steve is exactly what you want in a tradesperson.
He was very helpful and professional and also very accommodating of our requests.

He fit us a new boiler (relocating it) and set up a smart thermostat.

Ultimately the attention to detail with this has left us really happy so couldn’t recommend more!

Great response time and really professional manner. Came out and identified the problem and then came the next day and fixed it.
Great service

Totally brilliant! I needed an emergency boiler repair in Oughtibridge near Sheffield as I suddenly had an F75 fault and no heating and hot water. A friend recommended Jim at Thermofix and I’m so glad they did.

When Jim came out, I thought it might have to be a new boiler, as it’s a 15 year old Vaillant. To my relief though, Jim gave good sound advice, quickly and efficiently diagnosed the fault, and even brought the part, a pressure sensor, with him. Within literally hours, I’d got heat and hot water back, with no fuss and a super cleanup after. It’s usually a messy job when a boiler is drained but Jim even brought buckets and towels with him so there was zero mess.

Jim was kind, friendly and super efficient, and I’d highly recommend him if you’re looking for a timely and trustworthy boiler repair or service in the Sheffield area, from a boiler engineer who really knows his stuff. In fact I’m hoping to book Thermofix in this summer to replace the boiler and all the radiators. Thank you Jim for a super fast and professional repair at a very reasonable price.

I have used thermofix several times now to service my boiler and my mums. My mum had also used him to fix her boiler and central heating problems. We had Jamie. He is a genuinely lovely guy, reliable and comes at the time arranged. He knows his stuff and goes above and beyond to ensure you are entirely satisfied with his work. Thermofix are also very reasonably priced. I have since recommended thermofix to several other people and in both cases they were delighted with what was done.

Steve has fitted a number of boilers for me (I renovate properties) and he has always been reliable and professional. He's easy to deal with and really knows his stuff. I wouldn't hesitate to recommend him.

I had previously had work done on an old boiler by Gareth and Steve. Following a leak from a 45year old header tank and in discussion with Gareth I made the decision to have a new combi-boiler fitted. Work was carried out over three floors in awful weather and Gareth, Steve and Jim kept mess to the very minimum, cleaning and clearing as they went over the two days of installation. As someone living on my own I cannot recommend this team highly enough. They were friendly and efficient, explaining everything as they proceeded. I am confident in using the new system but also confident that should I have any worries they would respond immediately.

We needed our 24yr old combi boiler updating and was recommended Thermofix Services Ltd by a family member.
Gareth came out and gave us a quote for a new Baxi combi boiler which we were happy to accept.
Gareth, Steve and Jim, 3 of the politest guys you could ever meet turned up on time and did a brilliant professional job. On completion everything was left clean and tidy and the controls on the boiler and the new thermostat was explained to us.
We would have no hesitation in recommending Thermofix Services Ltd and will be having them back in 12 mths for our annual service.
