Another reviewer says the company was not interested in helping.
⭐⭐⭐⭐⭐ We have had a brilliant experience with Green Warmth from start to finish and would highly, highly recommend them. They designed the whole system for our house, including carrying out the heat loss calculations and sizing everything properly. We have gone from a 200-year-old house heated entirely by plug-in electric radiators to having solar PV, battery storage, an air-source heat pump, new radiators upstairs and plumbed-in underfloor heating downstairs. It has been a huge transformation for us. Everyone who worked on the house was brilliant. Friendly, professional, tidy and always really open with us whenever they came across an issue. There were inevitably a few hurdles along the way with a house of this age, but nothing ever seemed like too much trouble and everything was dealt with properly. You can tell they genuinely care about the work they are doing, not just getting it installed and moving onto the next job. They wanted everything to work properly, look good and be finished to a really high standard. The solar and battery performance has been fantastic, and the heat pump is now up and running really well. It genuinely feels like we have brought this old house into the 21st century and we are now getting the true definition of "Green Warmth"! A special thanks to Vicky for sizing and coordinating the heat pump installation, Tracy for sizing and coordinating all of the solar and battery side, and Danielle for seemingly always being at the end of the phone or email whenever we needed help with logistics or had another question! And a huge thank you to James, Osian, Ryan, Fiona, Creegan, Cameron and even the big boss Jason, who all worked incredibly hard on site to get everything installed. James in particular will probably never want to come back after battling his way through our 600mm solid stone walls! Thank you for persevering! The aftercare has been just as good. Whenever we have needed anything, somebody has picked up the phone and everyone has always been friendly, helpful and genuinely personable. It is really nice dealing with a company where you actually get to know the people involved. It was a massive project for us and we are really happy with how it has all turned out. A huge thanks again to everyone at Green Warmth. We would recommend them without hesitation.
Had a Sigenergy solar & battery system installed by Greenwarmth. They did a great job, installed with care and attention and provided a really detailed handover pack for me to get the best out of my system. Really pleased.
Just had my PV array and battery installation done by Green Warmth, and I’ve got to say, they were brilliant! The whole quote and home survey process was very smooth, and I was provided with great guidance and a selection of products to suit my requirements. The real stars of the show, though, were Creegan and Cameron, the two engineers who carried out the work. From the moment they arrived, they were friendly, professional and took great pride in the install. They kept everything tidy, explained things in a way that actually made sense, and were more than happy to answer my endless questions. I’m fairly sure they left the place cleaner than they found it. All in all, top-notch service and a genuinely enjoyable experience. If these two are anything to go by, Green Warmth is doing something right. Give those guys a bonus - or at least a biscuit and a cup of coffee (beans, not instant - they say like it but no one does).
Green Warmth have a highly skilled, well qualified team. During the initial survey, Electrical and Plumbing trades were represented and we discussed the physical constraints of the building, re the indoor units, positioning of the outdoor units, ASHP & Battery, to minimise visual impact and simplify installation. Installation of the Heat Pump etc. went very smoothly, it is almost a shame to box in the indoor units, they are so nicely fitted. The entire team have been very easy to deal with and the installation team have been a pleasure to have on site. The system supplies plenty of hot water and heating. Running costs compared to LPG are already down and I have yet to change tariff. 15 Solar Panels, a mid December install, we got a lucky break in the weather so Green Warmth sent a team of 4 to get our panels up on the roof in a single day. The guys worked hard, were well organised and by 4pm as the sun was going down, they finished. In the following days, the inverter, battery etc. were installed and commissioned. The whole team takes a great deal of pride in their work, which shows in the finished job. Once again they were very easy to work with and a pleasure to have on site.
By way of providing some real world information about running an ASHP, following the first annual service of out HP I sat down and added up all our electricity bills for the 12 months after commissioning. I know 2024-25 wasn’t a harsh winter, and that we have a lot of panels and a battery. but the total bill, not just HP but including all domestic consumption as as well of course, was £689.15. And that’d before we get paid for exported surplus. It’s also about what we last paid for a tankful of oil! Naturally we are well pleased!
great prompt service and professional workmanship and friendly staff
I contacted Green Warmth having just moved to Pembrokeshire and was looking for a green energy solution for our new home. They pride themselves on having everything in house, and that was important to me. I didn’t want the work subcontracted out and then poorly managed and had bad experience of this before. Tracy and Vicky were very thorough in the design and procurement process, clearing all my queries along the way. They took care of all the paperwork, liaising with National Grid, sorting out the grants….everything. The site team didn’t let them down. All excellent and worthy of mention….the two Cam’s, Sam, Jesse, Ryan and Ryan Jnr plus Jason overseeing. The work truly is top class, finished when they said they would and neat and tidy along the way. Can’t forget Olivia….chief organiser and always there to answer my calls, more often than not with the answers too. All in all, they are a great outfit in this field and know what they’re talking about.
We had our air source heat pump installed by GreenWarmth, very professional and local company. Victoria came to assess our home and was very knowledgeable and efficient, highly recommended!
Had this company to repair amd service our system. From the start Laura in the office kept me up to date regarding parts being ordered and when the engineer would be attending. Fiona attended the property, she was polite and obviously dedicated to her job as the work carried out was outstanding. Well done guys, you're a credit to the company. Would highly recommend
Green Warmth have been a fantastic company to work with for my project. From start to finish them have kept me informed, and done a brilliant specification for my build. I have chosen to have a heat pump and solar PV/battery installed. They were careful to spec all to the requirements of the property and at no stage were trying to just get a sale. ( there are some cowboys out there so watch out!!) The owners, office team and onsite technicians are all brilliant in their technical knowledge and installation standards. Installing this equipment is expensive and generally in life you get what you pay for. Green warmth are competitive and are always on the end of the phone to help. I highly recommend them and will be using them for my next projects in the future!
A great family firm, employing and supporting local people. They install only the very best equipment and are a pleasure to deal with. If you need renewables, no brainier support this business!
Green Warmth installed a full Air source heating system at our totally refubished bungalow, we were not too convinced on the choice of heating. Having moved in mid December, the heating has been briliant and we have been very confortable. Green Warmth, the installers, have carried out the work in a proffessional manner and remained punctual in their planned time schedule + a few days out sometimes due to weather conditions and the staff have also been friendly and helpful at all times. We have also had them install a complete Solar system and again we have been very pleased with their performance and proffessionalism.
Green Warmth are a local renewable energy and heating company based in Pembrokeshire and came highly recommended to me. Green Warmth provided me with a second detailed report of my heating and electricity needs after a comprehensive detailed survey. This was thorough and enabled them to design a system of air source heat pump and the requisite number of solar panels to provide energy to run the air pump. I went for their recommended package which included a battery to run with the panels. Green Warmth organised everything. Scaffolding, deliveries of heavy palettes, all on time, checked by their staff. Work commenced on the allotted day! The team of engineers, electricians and plumbers are a well organised team who communicated well. Yes there were hiccups and the odd delay but these were always explained and remedied. They even dealt with some difficult neighbours who feared that my system would be noisy! It’s not! Green Warmth ensured that all installations conformed with current Welsh regulations. So now I have a great integrated system that is quieter than my garden birds; an app that shows how much electricity is being produced and a smart boost that shows exactly what I’m using when I switch a kettle on! I happily recommend Green Warmth whole heartedly. The only bad news is that their reputation means you have to wait for surveys and installation due to the demand of would be customers! Worth waiting for.
We have just used Green Warmth to install our new air source pump. Ryan, Mark and Iuean did a very professional job and very tidy. They managed to answer all our questions. I would recommend them to others.We now have a warm house.
Did a very good job on installing roof mounted PV array and Inverter with built in EV charger. 2 years on, everything is working effortlessly and still looks freshly installed, despite being exposed to extreme wind and sea air. Had an initial problem with EV equipment not being installed to code, that the previous management refused to acknowledge. However Jason and the new team who have taken over were very understanding, they sorted everything out very professionally and at their own expense.
We commissioned Green Warmth as a consequence of the many positive comments from previous customers. Admittedly we were both unsure about the technology involved but Green Warmth took us carefully through each stage of the process, reassuring us that not only was the equipment they used of the highest quality but the technical support available post installation was readily available. Sure enough the whole installation process was smooth and efficient causing minimal disturbance. The fitters were very professional, courteous and above all clearly very knowledgeable and were well supported by the technical staff at Green Warmth, all of which we found very reassuring. The panels have now been installed and are generating power as we expected. Consequently, I can recommend Green Warmth to future customers without reservation. A very satisfied customer.

Industrial unit showroom for renewable technology and installation. Sat outside whilst grandson went for apprenticeship interview, online research seems like a good legitimate company with a good track record and diverse portfolio.
We had our air source heat pump installed by Green Warmth in Nov 2018. I'm not sure why I didn't review at the time - probably still too busy with our house build! Initially we couldn't afford it, but after some hard work and saving we replaced our electric boiler and couldn't be happier with our heat pump. It wasn't a problem that we had installed our solar panels already and did the UFH ourselves. They were efficient and professional. If I were to do it again I would move the pump a bit further from the house/put a bit more acoustic insulation into the room it is closest to. If you are looking for a company that has experience in this sort of set up then look no further :)
Very helpful in taking us through the whole process of setting up a ground source heat pump. Very responsive to requests
I would highly recommend green warmth. when I built my house 5 years ago they installed my air heat source pump and the solar panel systems. They also service my air heat source systems annually. Whenever I want any work done they were easy to get hold of on the phone Very polite and pleasant and the work they do was to a very high standard. If I ever build a another house again I would have them back any time to carry out any work for me.
Paul at green warmth was very helpful, and professional, his team did an excellent job installing our air source heating system, underfloor heating, plumbing and Solar panels. We have recommended him to other people and would continue to do so. First class service.
Had Green Warmth install solar PV panels on my newbuild property in Pembrokeshire. Great service, turned up when they said they would for each part of the installation and were always easy to get hold of via phone/email when I needed to ask the many questions over the course of the job. I was recommended by a friend to use them and I will be doing the same for other friends!
