Excellent customer service from 1st point of contact until installation which due to some tricky circumstances was about 12 months, no hard sell, just helpful friendly people who answered questions and provided all the information we needed. The installation team were very efficient and very tidy, a really slick operation all done in one day and you couldn't tell they had been there. 10/10 for everyone involved

Super happy with the service we got from SolarTherm. Very helpful and quick delivery for our solar battery - would recommend and use them again in the future. Thank you.

A bit of a confusing start as we had prices from both Solartherm UK and Silvercrest Energy Group only to find they are part of the same company, but we approached both and they are spaced out geographically so our fault for not checking !The reality was though that out of 5 quotes we chose 2 from the same outfit as both contacts from these companies seemed knowledgeable and non salespeople.Plus, our thinking was that this company has been in business longest, which must show as successful?We were not disappointed. The service from start to finish was near perfect and the help we had in getting our DNO, and application for export tariffs was much appreciated.Great company

Excellent service from start to finish. Great help in deciding what system to go for. Office staff back up was polite and friendly. The team of 4 who came to do the installation were friendly and polite working quickly and cleanly as a team and gave a clear explanation of the installed equipment. I would thoroughly recommend SolarTherm to anyone thinking of installing solar power.PS and so far the panels installed are more then meeting my expectations.

I booked a service visit with SolarTherm for Friday 5th April 2023, advised by the office they would arrive between 2pm and 3pm with a phone call when they was on route an hour prior to the appointment, Unfortunately they arrived late (4pm) with no notice. We had to go out and therefore missed the appointment.When the office called me to advise the engineer was at our door i advised they was late and we had to go out and we needed to re-arrange. Only at this point I was told the appointment was between the hours of 8am - 5pm and not a timed appointment and your appointment would have been between these hours!At this point I was advised a £50 missed appointment charge would be incurred if I wanted a new appointment I needed to pay the £50 or I could get a refund less the £50 charge. Sadly to say they was none negotiable on the missed appointment charge, and I opted for a refund less the £50 charge.I felt they was partly at fault as they never called prior to there arrival as agreed and they was late for the appointment time I was given, seen as they already had my money I had little choice or options and wasn’t able to get back for them in time to undertake the service.I will be using someone else for future service visits and will NOT be recommending them to anyone!I’ve since found a small local business, very friendly and helpful. They didn’t take an upfront payment for the service and the bonus was they come out Saturday 6th May 2023 and serviced my PV system.

Good sales & installation - aftercare not matching. Panels installed well and look good, seem to have a good output in the couple of months I've had them up. Had a few issues with how my property was left left by the installation team and was difficult to firstly get in touch with the after care team, but also the support that I received when I did get in contact - would not accept any fault on their side. The after care & accounts team have been incredibly rude since the installation and haven't helped or replied on many of my queries. When I ring them up and speak to them on the phone, a lot of unnecessary attitude is given, raised voices & throwing down the telephone. Honest opinion would be that if I had the chance to change my supplier now, I 100% would.

Just had a new solar system installed (11 panels and 2 batteries). Must say I was very impressed by the professionalism and quality of this company. Everything happened as it should have done. All the people from office staff to installers seem to know their subject well and everyone without exception was very pleasant to deal with. No hesitation in recommending them to others and I already have.

My installation of solar panels and batteries was completed yesterday and, whilst it’s too early to report on performance, I’m very happy with SolarTherm. They have been in the business many years and, based on my experience, I can understand their positive reputation. They gave me confidence that I was dealing with a reputable, capable organisation. The initial consultation was informative, the consultant was knowledgeable and happy to take time to answer my questions thoroughly. Following the physical survey I requested a small change to the spec which was accommodated without any fuss. One or two admin aspects needed follow up but I was given the mobile number for one of the team and he was impressive at picking up and sorting queries quickly. The installation team were superb despite awful wet weather - kept me informed, cheerful, friendly, courteous, helpful and left everything tidy.

The time it’ll take to install solar panels and complete the project will very much depend on the size & complexity of the solar project. Most domestic installations are completed in 1-day, however larger complex commercial installation can take a couple of weeks.

The cost of solar panels can vary dependant on several factors, including:

  • Size of the solar system
  • Type of solar panels
  • Brand of solar panels
  • Installation location

When installing solar panels, always ensure you chose an accredited installer, as this will enable you to qualify for tariffs such as the smart export guarantee.

The payback time on solar panels will depend on the initial cost of the solar panels, amount of energy used as well as the price per KWh. Our team at SolarTherm UK will conduct a feasibility assessment prior to any installation which will include the payback period based on your specific installation.
