Goeco Renewables Limited t/a 21 Degrees

They replaced my whole central heating, including 16 radiators, in 3½ days. Everyone was professional, polite and tidy. They also applied for the Boiler Upgrade Scheme on my behalf. I did have to organise getting my own electrics upgraded, and a trench dug (they recommended the contractor), so it took a little while to get a date that worke. But it was a surprisingly great job, and I'd recommend them.

This is one of three five-star reviews I'm leaving across the 21d network, for a recently completed ASHP installation in Norwich. My thanks go to Sonya for her help on the BUS paperwork and invoices. A great joined up team to deal with all around the country. Thanks!

21 Degrees York installed a 12 panel 5.46KW solar PV system with a 5KW hybrid inverter to my property in Huntington in February 2025. The whole process from the initial site survey with costings, estimated savings and environmental benefits, the necessary paperwork & approvals through to the installation was painless and handled by 21 Degrees for me. The team that carried out the install were top class, polite, attentive and clearly extremely competent. Everything went smoothly with no hitches including setting up my user account with the manufacturers phone app and cloud based reporting. Based on my experience I would happily recommend 21 Degrees York should you be considering a solar PV installation.

A few years ago I had Solar PV panels fitted to the roof of my house near York by the company now known as 21Degrees. (Formerly Green Buildings Renewables) The panels have been faultless since fitted and have saved me a small fortune in Electricity Bills. I have since invested in an electric car and charger I charge my car on our drive using the chargers Eco+ function. The Sun is converted by the Solar Panels into Electricity which charges my in house panels and my EV car. The company 21 Degrees are extremely knowledgeable and helpful.I can thoroughly recommend their services.

Used this company when they were Green Building Renewables, to fit a battery to our solar pv system. Getting the quote seemed fine and we were keen to use a local company - they had recently done a Solar PV installation for our next door neighbour. The install was not without issue. The installer somehow managed to drill from the outside, through the brickwork, through the cavity, through the plasterboard and into the internal room! He wasn't far off electrical cables coming up from a plug. He also left the driveway in a disgraceful state with sharp offcuts in an area where two small kids play. I informed them and they apologised. I meanwhile set about redecorating the damaged wall. He also complained to us when fitting that the battery was too heavy for a one man job - not sure that was anything to do with us?! Following the install, every time we went on holiday the battery would fill up and then the system would shut down. This took 3 visits by engineers who all diagnosed the issue differently, until one finally made a change that seems to have fixed it. Each time it happened we lost income from generation payments, having spent thousands on the battery itself. Fast-forward a couple of years and I needed a copy of some paperwork regarding the battery install that I couldn't find and got in touch with them to ask if they could help. No response to my emails. In the end I found the original. Then, I needed to get my generation meter replaced with an upgraded meter. Rang up the office, spoke to Daniel who abruptly told me to email him and he would come back to me. I did so, and got nothing in return not even an acknowledgement of the email. This was two weeks ago. Sent another email this time with my phone number added. No response. I also used the online form to request a quote for the job. No response. In the meantime I contacted another local company with good reviews. In the two weeks that I have had zero response from 21 degrees, this other company have provided a quote, answered all my questions about FIT eligibility, and attended this morning to replace the meter. Very helpful fitters who left no mess behind. I don't know what has happened to Green Building Renewables / 21 degrees, perhaps they have outgrown themselves. But the complete disregard they seem to show for existing customers is appalling. At some point in the next few years there is every chance I could upgrade my solar PV installation and/or install a Heat Pump. For the sake of not bothering to respond to me about a £200 job or some paperwork, they've now lost my business and looking at their reviews, I'm not the only one. I could never recommend these guys whatsoever.
