Had a few hiccups and delays during installation but was their first installation in a bungalow roof space. Design was spot on and performance excellent with savings made against previous gas system. Was also compensated with a first service free which was expertly executed. Would recommend.......and was the cheapest quote by far.

An excellent experience from quote to installation. They installed a solar installation on my property in York and even though I had to move the installation date at short notice, due to the roofers running behind schedule, they were able to accommodate my request. We had a couple of issues but these were dealt with professionally and in a timely manner. The installation team were very professional and ensured everything was operational and to my satisfaction before leaving. I am using their Huddersfield office for a MVHR system and whilst we are only at the design stage at the moment the service received has also been excellent. I would definitely recommend this company in the future

Do not touch this company. Installed new air source heat pumps and system for our new build home. Have had appalling service throughout, they send a different engineer each time who don’t know what the previous guy has done. We have moved in and still don’t have heating. The service is taking so long and we have been offered no compensation. We have had leaks, errors and no end of problems with it. I am fed up of taking days off work to let their engineers in to my home. This is a brand new system that they installed and they can’t even get it to work. It should have been completed months ago and I’m still having problems and work ongoing.
Take my advice - do not touch them with a barge pole.

They were easy to work with and flexible which is really helpful when you have a 60's building filled with community groups every day of the week from 9am to 10pm. The odd frustration in a 70k project is to be expected and more than balanced by satisfying some changes that we needed. I'd choose them again.

Prompt delivery and communication from Karen

From start to finish, 21 Degrees delivered a truly exceptional service for the installation of our solar, battery, and EV charging system.

Pre-Installation: 21 Degrees were incredibly knowledgeable and helpful during the initial site survey. 21 Degrees took the time to understand my specific needs and designed a system that perfectly matched them. I wanted a robust setup capable of powering our home independently as we both work from home, with any surplus energy diverted to the hot water tank and EV charging. Matt recommended a 10-panel, 4.4kWp solar array (south-west facing roof), a Tesla Powerwall 3 (which is a combined 13.5kW battery and 11kWh inverter), a Zappi EV charger point, and an Eddi solar diverter. This configuration has proven to be incredibly powerful, allowing us to run both ovens, an induction hob, and the rest of my house without relying on the grid during peak times! The quote was clear, detailed, and provided promptly. 21 Degrees also took care of the DNO application, which was approved in a remarkably quick two days, simplifying the process immensely.

Installation: The installation itself was flawless. The scaffolders arrived on schedule, were clean and tidy, and handled both installation and removal with professionalism. The team did a superb job on the installation. They were meticulous and even worked with us to route the cables through a void in the house, maintaining a clean and aesthetically pleasing installation. Working with limited garage space, 21 Degrees created a neat and functional setup that looks fantastic. The Powerwall and Gateway installation took two days, with the Zappi and Eddi completed on the third, and I was kept in the loop with every aspect before proceeding. 21 Degrees patiently guided me through setting up the two ecosystems via mobile apps, demonstrating how to effectively monitor and manage the systems. During final sign-off I was provided with valuable insights on optimising the system for maximum efficiency. 21 Degrees expertise and willingness to explain everything was greatly appreciated.

Post-Installation: All necessary paperwork and handover documentation were provided promptly after sign-off. I received all the required certificates (MCS, G99, etc.) to apply for an export tariff, whilst ensuring compliance with building regulations.

Summary: I am genuinely amazed at the speed and efficiency of 21 Degrees. The entire process, from initial consultation to final installation, was completed in just 21 days! Their communication was excellent, keeping me informed every step of the way. The installation team’s dedication and pride in their work were evident. I was also delighted to support a local company. Their quote was the most competitive among several local and national providers, and there was no pressure to make a sale. I wholeheartedly recommend 21 Degrees to anyone considering solar, battery, or EV charging installations. They are a truly exceptional company.

Savings: 4 months post installation the savings have far exceeded expectations, our combined home energy use, heating the hot water tank, and EV charging (travelling 3,984 miles, all charged from home) has come to a grand total of £11! saving us £1,455 vs our old, standard tariff and ICE car. We have generated 2,417kWh in solar, Imported 4,029kWh from the grid during off-peak rates @ a cost of £288 and exported 1,848kWh, generating an income of £277 netting out at £11. Incredible!

A fantastic company who couldn't be more helpful. I had a range of questions about airtightness and I was given all the help I needed (and more) to help make a decision on what products to buy. Will be a returning customer for sure.

They were off to a good start because both my brothers had used them. I got a couple of quotes and they were about right.

Everything happened as they said it would from Scaffolders, to fitting the panels, Battery and then the sparky doing his thing. Good set of blokes who didn't need too much Tea:) Talked through everything and now I'm saving a fortune and making money off my export. Set up looks good and neighbours are asking for their number - I have no hesitation recommending them.

Very professional. They do what they say, when the say they will do it. They designed and certified our Mechanical Ventilation System which is extremely quiet, extremely well balanced and only uses 25 W to run. Extremely happy to work with them.

Easy to order very quick delivery

The Installation ran very smoothly. Very helpful from start to finish. Good communication throughout the project. During the two weeks of fitting the panels and batteries, the lads on site worked hard and we were kept informed of developments as the work
progressed. I would certainly recommend 21 degrees to anyone considering having solar panels installed.

Having recently moved to Hollowell, we were looking to replicate our old system. Following our initial contact with the company, we were impressed with the professional interaction, suggestions and advice.
This continues with the survey, and then the fitting, all of which were better than our expectations.
This is a rare thing, I would have no problem in recommending this company to any prospective customer.

the installation started well with the survey being thorough and carefuly explained. the team of engineers worked well in and around our house to get it all done - and their was a lot to do. despite a slight overrun the job was completed in good time and handed over by the lead team member who explained what we needed to know. we were pleased that the team made minimal mess or disruption as the instal took place too.
apart from rememebring we would need a main fuse change a bit too late get it done before everything was finished we have been very pleased with the way everything is working so far.

Great service. Fitted us in at short notice to install an ev charger. They’d previously installed solar panels and batteries for us, so we knew we’d be in good hands. Great support with questions on the phone after.

I recently had an air source heat pump installed by 21 Degrees and following a few quotes and on site meetings from various companies I went ahead with 21 degrees. Firstly 21 degrees were the best price on a like for like basis and following an on site meeting with Mark and Natalie, the service and professionalism along with the knowledge they had was excellent. The team who installed the heat pump were punctual and provided me with an all round excellent service. They were very friendly, tidy and excellent at their job. I was kept informed at every stage of the process too. Thank you to all involved at 21 degrees, I would highly recommend to anyone thinking of having an air source heat pump.

Very diligent in ensuring we had the right model and responsive in getting it to us quickly.

Thank you to the team for installing our solar panels & Tesla powerwall 3.
Tidy and efficient and so far working great and saving us money.

MVHR service is personal and detailed. I worked with the designer to review and refine the detail until we were all absolutely satisfied it will work. It makes developing an MVHR scheme a pleasure.

The workmen were wonderful and put right any minor issues that resulted from having to take out the windows. They even put back our roller blinds!
They friendly but undemanding. They also came when they said they would and the work was well co-ordinated between them and finished on time.
