  We shopped around for our solar system. Three One Solar were really competative with the price and presented us with a solution for our specific needs that the other companies we spoke to didnt seem interested in asking us. Once the G99 came back installation was quick and efficient. Highly reccomend Three One Solar.

  Brilliant service from start to finish. Callum was knowledgeable, professional and really helpful throughout the whole process. He explained everything clearly, gave honest advice and the installation was carried out neatly and efficiently. We’re already seeing the benefits from our solar and battery system. I’d highly recommend three one solar to anyone thinking about getting solar panels.

  Had Callum and Three One Solar fit a system to our garage roof in August ‘25 and we have been delighted with results so far. 14 panels and a 10kw battery have been a great purchase. Three One Solar were very professional and I’ve already recommended them to friends who are thinking about fitting solar panels. Our first electric bill saw our Direct Debit drop by £30 per month and I’m expecting more savings now we’re past winter and we’ll get a full year of generating. Callum has appeared only too happy to answer any of my concerns so can’t fault their after sales service either. Amazing how additive it is to check performance on the app every time you see the sun coming out even while you are away at work! Understandable that it will take some time to pay off initial investment but I’d definitely recommend checking these guys out.

  The lads done a great job, had shopped around and all the other installers told me I couldn't do what I wanted. No problem to these lads thanks again

  Fantastic job done, very professional and kept me informed every step of the way, also helped remove weeds from my chimney out of kindness as I’m unable to get up there myself, really happy I chose Three One Solar and I highly recommend to anyone looking for a reliable trustworthy company for your solar panels, these are the guys to call.

  We reached out to multiple companies when thinking about getting solar panels and we decided to go with three one solar due to competitive pricing and also the way Callum answered all the questions confidently that I had regarding the installation. We are very happy with how the install went and now 3 months later we are definitely seeing the benefits of having our solar and battery storage.
