The excellent and efficient team arrived promptly and installed our Air Sourced Heat Pump and underfloor heating in less than a week and we are very happy with the results so far, and the aftercare has been very responsive when they were called to fix a minor issue with system pressure after commissioning. The remarkable pipework in the loft is the neatest I've ever seen and resembles an art installation.
Very neat installation, place left clean and tidy, and I have nothing to complain about.

We had a fantastic experience with Ecofueled. From our very first call through to the actual heat pump installation at our home in Marston in Oxford, their communication (Amy and Ellen), expertise (David did the survey for us) and professionalism (Don and Harry) were outstanding. We wanted to make a few changes to the original design along the way, and they were incredibly responsive and efficient in finding solutions and making the changes work. The whole installation was handled smoothly and professionally. Their value for money is also excellent compared with other installers we looked at. A fun fact is, when I first asked ChatGpt to recommend a few trustworthy choices, it put Ecofueled on the very top of the list. And they somehow proved that they deserved that spot.

We used EcoFueled for our PV and battery installation and found everyone there very professional and easy to deal with. The team remained responsive throughout the whole end to end process from quotation to post-installation support. I highly recommend them.

From the first time I got in touch with EcoFueled to the end of the installation of my solar panels and battery system I could not of asked for better customer care from all the TEAM. The initial contact and process was never a hard sale to get me to have it. They did a very comprehensive report on my house, where to install the solar panels and what kind of power I could generate with state of the art software. The report was professional and easy to understand. They advised me I did not need panels on the front of the house and I could easily generate enough electricity to power the house and pump some back to the grid earning a small income from installing a larger battery. They could have easily sold me more but did not. The installation was pain free, with them organising the scaffolding to go up, next day solar panels fitted, followed by all the electrics the following day. On completion Shawn came around and guided me through the App on my phone in plain English and Ellen sent me all the paperwork and guarantees for the work carried out, she even sent me the documents to get in touch with my provider to set up the contract for them taking energy from me. The whole experience was 5 Star and I did not have to take any time off work for the installation. A very Big thank you to all the Team at EcoFueled.

Our air source heat pump was installed by Jack, Lee and Shaun. Their working ethic is absolutely second to none. It took three days to complete and simply looks like it’s always been there. We live in a bungalow with little storage therefore the tank was installed in the loft. The heating side - we can’t comment yet, not needed to use it but for hot water it’s brilliant. No difference to our combi boiler. We’ve needed to adapt our way of thinking - think back to hot water tank days but better. Jack, Lee and Shaun most definitely know their stuff - it’s like watching strictly come dancing crossed with plumbing, heating and electrics!! Seamlessly flow together. The system install is neat and professional. When the guys left - they cleaned and cleared everywhere they’d been. Hand over for the system was robust and informative - in terms that we understood. Ecofueled are on hand should we need them for any follow up questions. The heat pump went live three days ago and we can already see the difference in our energy bills. Ecofueled is definitely the company you want for your installation. They have awesome crews, fantastic customer service and competitive pricing.

From first contact to meeting Shaun for the assessment and quote, to finalising completion, the team at EcoFueled have been amazing. We moved from an oil system to an ASHP with solar and battery. The team in the office were always available to chat through ideas and the team were accommodating to some specifics we had. Everyone involved was knowledgable and those on site also worked relentlessly to get the whole system completed on schedule. The system is running beautifully and our outgoing energy costs are slashed! Huge thanks to the team - would 100% recommend!

Highly recommended – Professional and Neat! ​I recently had EcoFueled install an air source heat pump, and I couldn't be more impressed. From the initial consultation to the final handover, the entire process was seamless. The installation team did a fantastic job—not only is the system working perfectly, but the workmanship was incredibly neat and tidy. It’s rare to find a company that takes such pride in the "finish" of their work. If you’re looking for a reliable, professional team for renewable energy, look no further than EcoFueled!

EcoFueled installed an air source heat pump system at my house just over a year ago and have recently carried out an annual servicing. Very satisfied with them. One thing I'd particularly highlight as a positive is that their servicing package, as well as being very competitively priced, INCLUDES re-dosing of Glycol anti-freeze. I initially did my servicing through another company at they were about thirty pounds cheaper (which I assumed was because they were more local and had less far to travel) but afterwards they quoted me an additional three hundred pounds just to top up the glycol levels. So I very highly rate EcoFueled, especially for their annual servicing of ASHP.

We have had our Midea air source heat pump installed since September. We live in a 1950s semi, therefore it doesn’t have modern installation. The heat pump has dealt with wind rain and very cold weather this winter and has kept the house comfortably warm. The team that did the installation were hard working and extremely polite.

In December 2025 my Wife and I decided we would convert our house to 99% S0LAR POWER. We already have 20 solar panels and we decided to have a Heat Pump installed. I purchased a further 8 Solar Panels to help power the heat pump. We chose EcoFueled of Poole to carry out the work. Our house was warmed by a gas warm air system and hot water was via a gas water heater. This was a very big job as EcoFueled had to remove the old gas warm air unit and water heater system. 6 new radiators and pipe work then had to be installed. Eco Fueled also supplied the Heat Pump, water tank, all necessary pipe work for the pump and electrics for operating the system. The job took 4 days and all staff were very professional in carrying out the work. Nothing was to much trouble for them and the house was left very tidy after each days work. We were very impressed by the standard of work. The paperwork from their office was promptly sent out and all necessary documents sent to us. Everything is working and providing the heat we require this winter 24/7. We fully recommend the company 5 ***** Star. ( We retained one gas fire and a gas hob in our dining room /kitchen) Nick & Sue Hanham Poole, Dorset January 2026

Ecofueled installed an air source heat pump for my elderly parents and were absolutely brilliant. The team were professional, patient, and took the time to explain everything clearly, which really put us at ease. The installation was smooth, tidy, and the system works perfectly. It’s made a big difference to my parent's comfort and peace of mind. I’d highly recommend Ecofueled to anyone looking for a reliable, trustworthy heat pump installer.

I recently had EcoFueled install an air source heat pump and the service from start to finish was brilliant. Firstly, Callum was extremely helpful over the phone and took the time to explain how a heat pump would work in my home. He gave me an estimate which I was surprised by, as it was much cheaper than I was expecting. Because of this, I arranged a full on-site survey. They sent a guy called David out, who I later found out is actually the owner of the company, which makes sense as he said he’s been a heating engineer since leaving school. His knowledge really helped me make my decision, and I was happy to see the price stayed the same when the full quotation came through. We went ahead with the install and the fitting team were clean, tidy, and got everything completed within 3 days from start to finish. David then returned to carry out a full handover. Abi from the office rang the next morning to check we were happy with everything, which we were. I wouldn’t hesitate to recommend EcoFueled to friends or family and I’m looking forward to seeing how it performs over the next 12 months. Thanks again ecofueled! ❤️

Great service from the start to installing my air source heat pump. Turned up on time, very tidy and explained how the new system worked. David from Ecofuled was absolutely brilliant. Our heat pump broke down and he dealt with everything under warranty quickly and professionally. While it was being repaired, he kindly provided heaters, which was a huge help. He kept me fully up to date throughout the whole process and clearly explained what was happening. After the repair, he also checked in to make sure everything was working properly. Excellent service from start to finish — knowledgeable, reliable, and highly recommended.

We live in Reading and have had our boiler replaced with a Mitsubishi heat pump making use of the government voucher of £7.500 which made the heat pump hardly any more expensive than a new boiler. Ecofuled with David, Abi and Harry have been very friendly and professional. Dom installed the cylinder in the attic and heat pump outside together with Harry and their work has been brilliant. We now have extra space in the kitchen since the boiler is gone and a completely free airing cupboard which we can use for storage. We also had 10 radiators replaced because ours were very old. The team tried to fulfil all our wishes and do everything the way we wanted it at no extra cost. There were a few communication issues. So, it is best if you know exactly what you want and know what you need to ask. But all in all we are very happy with the results and if we go for solar panels in the future we will ask Ecofuled to install them.

We couldn't be more delighted with our experience of working with David, Amy and the rest of the team. We were deep into our house extension and full refurb when we decided to explore the idea of heat pumps & solar. David stopped by within hrs of the first call to the office and walked us through the possibilities and whether our house would be a good candidate. David instils a lot of confidence with his obvious experience and expertise so we asked for a proposal for both air source and solar. When it came to install, the guys onsite were professional and polite, and communication throughout was superb. The system has worked perfectly since commissioning and David has stopped by to make sure we were using the system in the most efficient way. His patience for stupid client questions is appreciated 🙂 We wouldn't hesitate to recommend EcoFuelled to anyone thinking of making the switch to Air Source and other renewable solutions.

I can't fault EcoFueled. They were prompt, competitive, and efficient. The installers were neat, the workmanship was tidy, they managed to fit everything within the limited space available and the system works. And to top it all, no pushy salesmen - they gave me space to make my own decisions in my own time.

Excellent. Serviced my gas boilers also done many jobs for me in the past. Always does above and beyond what is necessary. A superb company. I had an emergency problem with a water heater that stopped working. In spite of short notice, David fitted me in. Within a couple of days a new heater was efficiently installed, the old one removed with everything left clean and tidy. Thank you very much.

Wow, what can I say !!! Absolutely brilliant service. I noticed that my water wasn't as hot as normal on Tuesday of this week. Wednesday it was none existent. I contacted my landlord who contacted EcoFueled. She asked me to contact them direct to explain the problem and send photos of the water heater. EcoFueled communicated directly with me. This morning 2 lovely lads arrived at 0745 and by 1000 I had a new heater fitted and working. The lads were absolutely brilliant, got on with the job, with no major disruption to me, and they tidied up when they'd finished. I can't recommend EcoFueled highly enough. Thank you so much.

Recently received my annual visit to check over my hot water and heat pump. David from ecofuel was as always extremely efficient very professional and extremely helpful during his visit. David is truly very knowledgeable and answered any of my concerns regarding my heating installation. I would definitely recommend ecofuel/David or his team to enter your home and ensure that your heating system is professionally serviced by an excellent company that understands customer satisfaction.

Updated the bathroom in our bungalow which involved extensive work on concrete floor to bury pipework. Work started on time and continued to completion. All workers were personable, polite and took care. The resulting bathroom is beyond our expectations. We cannot praise them enough. After completion there was a small problem with the toilet which was fixed without fuss first thing the following morning after informing them. We have absolutely no reservations in highly recommending Ecofueled. Thank you to David, Amy and team.
David, Dom, Amy and the whole team (sorry I can’t remember all your names) have been outstanding from the outset. The price was very competitive and they clearly all have a brilliant understanding of ASHPs. The speed they worked at was incredible and they have done a very neat and tidy job. We have used the system albeit in the summer months and it appears to work very well. They took time to let us know what they needed to do and checked we were ok with even little things, which was appreciated. There was a very small issue during the install but this was sorted in a matter of hours and left us feeling in very safe hands. They were respectful to our home and kept everything tidy. I have no hesitation in recommending them to others and look forward to using them in the future for other projects. Thanks again Ash.

I recently had my underfloor heating serviced by Ecofueled, and I couldn't be happier with the experience. The engineer was knowledgeable and helped me fully understand the system. The service was prompt, and the team's attention to detail was evident. They turned up on time and were professional throughout. Great communication and a hassle-free process from start to finish! I will be using them again!
