    We used UK Alternative Energy as part of a recent government grant scheme. We decided to have an air source pump to replace our old gas boiler. From start to finish we’ve had great customer service from the company. Everyone from the company who has been in the house has been approachable and friendly and have worked within Covid guidelines and left the house clean and tidy. Dan, our technical renewable energy advisor has been fantastic and has answered any questions we’ve had promptly. We’re really pleased with the system and would definitely recommend them to others. We will be using them again in the future for further work. Thank you!

    We were wanting to change our oil heating system and the quality of the service provided by them from start to finish has been extremely knowledgeable, and professional. Mark our renewable energy advisor came and surveyed the 4 bedroom house and area, gave us all the information and patiently answered all our endless questions. Another Mark, the engineer and his crew have delivered outstanding quality of workmanship during the whole week long Covid installation process. They have been extremely tidy, considerate and conscientious. We had a perfect experience and know that any teething problems that may arise they are ready to help on the end of the phone or by a visit. Well done guys. Anyone looking to invest in an Air Source Heat Pump should look no further than UK Alternative Energy.
    Thank you!

    I have used UK Alternative Energey for both my Solar PV and Air Source Heat Pump. Both jobs were competitively priced and the after sales support has been excellent.

    I had solar panels and the Tesla powerwall installed in late November. Not the best time of year to have solar installed with low sun, shorter days and cloudy weather. Wanting to reduce our own carbon footprint, this seemed the best option. I also wanted to use a local company with experience in this field and UK Alternative Energy ticked all the boxes. They offered unbiased advice and were keen to answer questions that I had. We encountered a delay in getting the Powerwall up and running but this was soon resolved (hence 4/5). At present I am generating just under 10% of our electricity needs with a best of 20% on one sunny day. I am hopeful that as the days get longer and sun gets higher that this will dramatically increase, with the aim of being completely off grid for part of the year. I would definitely recommend UK Alternative Energy, a local company providing a good level of service and reassurance that if I have any issues they are only a phone call away. Thank you Lee and the team.

    They've been great from the start, always happy to help, friendly and clearly know their field well.
  • Matt Everett
    From start to finish UK Alternative Energy have been spot on. Answered every email or phone call promptly. Thoughtfully answered every question we had and walked us through the process of having air source heating installed. The team that did the installation were also excellent. Very professional, knowledgeable and we cannot fault their workmanship. Afterwards they’ve walked us through the process of applying for a RHI payment from Ofgem which would’ve been tricky without UK Alternative’s guidance. All in all we are thrilled to bits with our new heating and with the service we received.

    The quality of the service provided from start to finish has been extremely knowledgeable, timely and professional. I’d like to personally thank Carl for the quality of workmanship he has delivered during the whole installation process. He’s been extremely tidy, considerate and conscientious; ensuring a perfect experience and making sure the job is right first time with zero defects.
    Thank you!

    I would heartily recommend this company if you are looking for a good supplier for renewable energy installations. Their sales people are more engineering consultants than horrible pushy sales people. They really know their stuff and were VERY helpful. They guided me through every step of the process including getting the RHI rebate from the Government. The installation was also very smooth and well managed with frequent visits from the company to make sure the work was proceeding as planned. The electrical and plumbing work was all done to a high standard with very well mannered, competent technicians. Having the company relatively local to me is also a big plus. I really cannot fault them and I'd be happy to speak directly to any prospective customers.

    Derrick offered a great product at a competitive price for our commercial properties solar PV installation. The work was carried out as discussed to a great standard and all rubbish taken away (a rarity these days!), as well as all paperwork and guide on the FIT completion. I’d have no hesitation to recommend Derrick and UK Alternative Energy.
  • Stephen Holdaway
    WE have been delighted with the installation of solar panels and an immersat device to heat the hot water by UKAlternativeEnergy. Derrick gave us an excellent explanation of how the system would work and what the benefits would be and gave us a keen quotation. The scaffolders and installers were polite, tidy and efficient and completed the work in a day. Derrick then came and helped us with the FIT application and informed the District Council. An excellent service that I would highly recommend.
  • John Shaw
    I was very happy with the advice and survey provided by UK Alternative Energy, we have a bungalow with east-west facing roof but the solar panels were fitted to take advantage of the best angles. Also have the Immersat device to heat the hot water via the panels, since fitting it only used the gas boiler to boost the heat once. The company sorted all of the paperwork and informed the local council to comply with building regs. Looking forward to many years of service thanks.
  • Robin Shipston
    There's a few variables to get right to end up with a PV system that's right for your own individual circumstances and aims. UK Alternative Energy has both the knowledge and the access to a range of different components, to design the most appropriate solution. The service is great from start to finish, and quick too. There are good reasons why all the reviews are 5 star.
  • Kevin Sharples
    There was a slight mix up in communication, mainly due to me losing my phone. It was sorted well and we were very happy with the service and the people who carried out the

    Ours was not a straightforward job - panels on three sides with scaffolding over a garage and conservatory and they were not phased by this.

    Derrick is very good at explaining details, and took time to fill in all the paperwork on completion. The whole team was very good.

    We wouldn't hesitate to recomend the company
  • Julia Higham
    Our Airsource system is up and running. Installed without a hitch, the fitters were clean, tidy and efficient. We are very impressed with it.
  • Hazel Redmile
    Within 2 weeks of speaking with them and getting quote we had our panels fitted. quotation was very reasonable and the work was carried out (on an extremely hot day) by two very friendly and hard working men. Extremely pleased and would highly recommend this Company..H Redmile
  • Rebecca Baines
    Only had the system fitted end of March, and we have already received our first FIT payment. We would highly recommend UK Alternative Energy. They make sure, even at the last possible moment, that your panels are in the best place to utilise the sun. You wouldn't of known they had been to fit the system if it wasn't for seeing the panels on the roof. From start to finish they have been quick, professional and very helpful.
  • Chris Parkinson
    I have had the system now for 15 Months, my FIT payment for the fist year was more than I had allowed for and a welcome cash boost, my biggest gain is in the reduction of my monthly fuel bill, a saving to me of around 60% well exceeding the projected figures. From start to finish the advice was good and the installation process was professional and quick. I have no hesitation in recommending UK Alternative Energy.
  • Rachel Martel
    Have had the panels a couple of years now. Installation was smooth and easy, with next to no disruption. The staff were very helpful and informative. The panels heat water and send surplus energy to the grid. I claim the FIT payments periodically and they are always a welcome cash boost.
    Would recommend wholeheartedly - buy before the tariff decreases in January!
