Fast, punctual and to busget
I contacted them as a Which provider and was not disappointed. I wanted to reduce my carbon footprint and long term costs. My initial contact was with Ben who explained the options, the process and the options. He was reticent to suggest panels as there were other options to reduce costs and the payback was longer than they like. I went ahead with panels and every step was completed on time and with considerate people. The panel fitter even replaced some broken tiles without prompting. The panels are now up and running, the app shows me the energy generation and I am now working with the team to optimise my energy plan. Great company, great people, highly recommend them.

Really Responsive Supplier
I first saw their clips in TikTok, and it was clear they had experience of the Fox ESS equipment that I was interested in. The response to my enquiry was highly professional, and Certified Renewables really listened to what I needed, and complied with a great solution. The installation team they sent were equally impressive. Many thanks to them both, and I will use Certified Renewables again as my system needs extend over time.

Excellent solar panel/battery installation
I chose Certified Renewables from Which? Trusted Traders to install solar panels and a battery. Ben came to see me the day after I contacted them and already had a mock-up of where the panels would go, a quote and a time frame for installation. Ben and his team were so professional, knowledgeable and helpful throughout and I am so happy with the end result. I have already recommended Certified Renewables to friends and hope to inspire more people to move away from fossil fuels. Many thanks to Ben, Sam and the fantastic installation team!

Exceptional Service from Certified Renewables
Exceptional Service from Certified Renewables Certified Renewables was recommended to us for their level of customer care and attention to detail. Their professional standards and direct support have been a feature for us since our fist contact with Ben who offered us an honest appraisal on his first visit. His care and support in dealing with issues which inevitably arise has been so much more than remote ‘customer care’. He really does care and takes time to create ‘smooth paths’. Nothing seems too much trouble and he persisted in checking how we saw and felt about the works going on. Sam and the office team have also been wonderfully responsive to all our questions as well as showing infinite patience in guiding us through setting up stages. They can look at our system and advise us. Communications have always been clear and thorough so we have documents to which we can refer. The detail and execution of all these steps is far beyond us, but the team has guided us so we now have an effective solar energy system which is earning us money from the summer sun!

Solar Panel System
When I started to look at solar panel systems for the house I spoke to countless companies. Who knew that the one I settled on was a stones throw from my house. I spoke to a couple of people .. from the initial phone call and home visit I was put at ease. My primary goal was to pay as less money to my energy provider. The system that I got far outweighs what I use and net result I am making money by selling back to the grid / use it to pay for my gas - over a period of 3 to 4 years the system would have paid for itself and thereafter it's generating me free energy. The solution, design, advise, communication throughout has been second to none. Sam was my main point of contact and he was great - even understanding my personal circumstances and simply said I concentrate on that and he will take care of everything - true to his word he delivered. Aftercare has also been great.. when the time is right and my boiler packs up I will go back to this company for the heat pump install. And if ever I decide to go for an EV will go back to them. Thanks to the team for a seamless install.

Super smooth install!
Excellent experience having solar installed by Certified Renewables. Ben handled everything in the run-up to the install — clear, knowledgeable, and made the whole quoting and design process easy. Install day itself was smooth, on time, and tidy. Sam then helped me get my solar export set up and was just as responsive to every query I had. Super helpful team across the board. Highly recommend Certified Renewables to anyone looking for a trustworthy solar installer — communication is first class and they really know their stuff. I know everyone must say this, but I really do wish I installed solar sooner! Thanks again guys!

Great service with Certified Renewable Solutions
I had a great experience with Certified Renewable Solutions Ltd. From the initial consultation through to installation, Sameer & team was professional, knowledgeable, and genuinely helpful. They took the time to explain all the options clearly and made sure everything was tailored to my needs. The installation process was smooth and efficient, with minimal disruption. The staff were punctual, respectful, and kept everything tidy throughout. It’s clear they take pride in their work and customer satisfaction. Since using their services, I’ve already noticed the benefits in terms of energy efficiency and cost savings. I’d definitely recommend Certified Renewable Solutions Ltd to anyone looking for reliable and trustworthy renewable energy solutions.

Fantastic experience - highly recommended
We had solar panels and a battery installed. From the initial contact to the finished installation, Ben and the team have been amazing. We have had support and information every step of the way to help us understand what would be best for us, how the solar panels work, what the installation involves, and what the costs and savings would be. The installers, Lee and Charlie, were very friendly and did a great job (including cleaning up!). Have already recommended Certified Renewables to my parents!

Customer focused and exceptional work
I used Certified Renewable Solutions to install Sigenergy batteries and a Daikin ASHP. Both installations went very smoothly and the service provided was superb. I most appreciated the service for the ASHP, because I approached 3 other companies beforehand: one said I had no space to put the ASHP, the second said they could not provide an ASHP large enough for my property, the third said they could provide the ASHP but only near my front door, which I did not want. Ben was the only person who actually listened to what I was trying to achieve (with the ASHP in the back garden) and took the time to work out a solution for what was a somewhat more complicated installation. It was such a relief dealing with someone who tried to meet my needs rather than find a solution which made live easier for the installer. The installation itself was carried out very professionally, the workmanship was exceptional, and the garden and the house were left clean and tidy after completion. Ben and Sam have provided useful advice/aftercare and resolved a number of questions about the operation of both the battery and ASHP (and their apps) since completion. I can't recommend this company highly enough.

Great experience
Recently had a daiken Ashp installed - install went smoothly and a special mention to the installers who were polite and helpful throughout the whole installation. Price was competitive and after sales was even better. A special mention to Ben who took time out on a Sunday and came to explain and optimise the system. Sam was great also and took care of all the paperwork and grant applications. Would definitely recommend certified renewables if you are looking for Ashp.

I love my heat pump!
Ben was amazingly patient explaining the costs, savings and process of a heat pump installation and Sam made the paperwork and application for the government grant very easy. We are so happy with the Daikin heat pump-our house is much warmer and we have plenty of hot water. We also had solar fitted which makes it all very economical to run. It is also very quiet snd easy to operate. Ben has given us outstanding aftercare and is always on the end of the phone to answer any questions. I would absolutely recommend this company.

Review 1: Solar Panels – Energy Savings & Smooth Process
We decided to invest in solar panels with Certified Renewables and couldn’t be more pleased. Ben explained clearly how much we could save on energy bills and guided us in choosing the right size system. The installation was quick, neat, and hassle-free. We’re already seeing lower electricity costs and feel good about making a greener choice. Highly recommend them for solar solutions!

Solar panels and battery
My experience with Certified Renewables was excellent. I first contacted them through Instagram and Ben replied to me immediately and set up a call same day to go through my options and what I would like to have fitted. Everything was very transparent in terms of pricing and the equipment choices we could have. Ben then arranged to come down and have a meeting in person before I agreed to anything - there was never any pressure to go through with anything. The team that supported us was fantastic, from the surveyors to the installation team and of course Sam in the office. Sam helped us get the whole system set up with an app and to contact our energy supplier to get the best tariffs and set up charging systems. I would highly recommend this company and their professionalism.

Outstanding Service and Results
We had our solar panels and battery installed by Certified Renewables and couldn’t be happier. Sam was brilliant from start to finish. He explained everything clearly, kept us updated throughout, and made sure the whole installation went smoothly. The team were polite, tidy and really knew what they were doing. Our new solar and battery system is working perfectly and we’re already seeing lower energy bills. It feels great knowing we’re using clean renewable energy and making the most of what we generate. A big thank you to Sam and the whole Certified Renewables team. I’d recommend them to anyone thinking about solar panels or battery storage.

Expert Team and Excellent After-Sales Support”
Certified Renewables installed our heat pump during a house renovation and I was very happy with the service. Ben provided clear advice, was patient throughout, and coordinated well with our builder. The installers, Darius and Michael, were thorough, professional, and did a great job. Pricing was competitive, and the after-sales support has been excellent – Ben is quick to respond and has fine-tuned the system for efficiency. The house is comfortable and bills remain reasonable. Had I known them earlier, I would have gone through Certified Renewables for all of my renewable kit. I’d recommend them to anyone considering a transition to renewables.
