5/5

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!

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.

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!

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
