Customer Reviews
"Poor communication , do not answer the phone!! after at least 5 visits my Mitsubishi heat pump installed by this company is still not working. Every visit throws up another leak and problem. I would not recommend this product or company ."
"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!"
"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."
"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."
"Green Building Renewables York installed a solar PV system and battery storage for my Mum in Leeds. I was delighted with the service they offered her. The communication was fantastic. The install was completed in just a few days and the team were fantastic. They were even able to explain to her how it all worked. It's so simple. I am delighted to say she is a full solar energy convert now and loves tracking how much energy her battery has on the app and seeing how little energy she is pulling off the grid. She loves updating me on how much charge her battery has. Highly recommend the company."
