Optimal Energy Solutions Ltd

⭐⭐⭐⭐⭐ I can’t recommend this solar company highly enough. They installed a new inverter at my grandad’s property within just two days of identifying the issue, which was incredibly efficient. As I hold Power of Attorney, they kindly phoned me beforehand to ensure I could attend the appointment. I really appreciated this thoughtful approach. Although the visit was initially a health and safety check, they took the time to clearly explain all the details of the installation process and what needed to be done. The gentleman who came out was absolutely lovely – so kind, patient, and professional. He didn’t just inspect the inverter; he carefully showed both my grandad and me the readings and explained how they had been decreasing over the last five quarters. Everything was explained in a way that was easy to understand, which gave us great confidence in the work being carried out. The installation was completed within a week, and we truly couldn’t be happier. My grandad is over the moon with the outcome. A fantastic service from start to finish – highly recommended!

Brother signed up with this firm (13/11/25) for a 10 year maintenance plan at a cost of £6000. They promised an engineer within three weeks to sort out the issues we were experiencing eg 2 of 16 panels not working and two optimisers faulty. within three weeks of signing maintenance contract they arrived to wash the panels (??) and now after 2 months we haven't seen an engineer. We've tried to contact the office - lady on phone continually told me she needed to speak to her diary manager - promised to call back within 10 mins. however, she didnt call back and now we cannot get anyone on the phone.

After being messed around by multiple companies who never bothered to return my calls, finding Optimal Energy Solutions was a breath of fresh air. They have maintained my system for two years now, and without fail they contact me every year to arrange servicing and cleaning. Their reliability really sets them apart. When my inverter stopped working, I contacted them and they had it replaced within a week. I’m genuinely thankful for the effort and care they’ve shown me from the very beginning. Excellent service all round.

I recently had the opportunity to take advantage of a free health and safety assessment for my solar panels, courtesy of the Optimal Energy Soultions, and I couldn’t be more impressed! From the moment I booked the appointment with Eden who was informative and polite and a pleasure to talk too the entire process was seamless. The team was professional, friendly, and arrived right on time. They took the time to explain everything in detail, from the inspection process to the safety measures they were checking for, ensuring that I understood the importance of each step. The technician was thorough, conducting a full evaluation of the panels, wiring, and connections to ensure everything was in top condition. They identified a couple of minor issues that I wasn’t aware of but assured me they were easy to address and provided me with a clear action plan. What really stood out was the level of customer care. They didn’t rush through the assessment, and they took extra time to answer all of my questions. They even offered tips on how to maintain the system to extend its lifespan and keep it performing efficiently. I’m incredibly grateful for the peace of mind this assessment has given me all it cost me was a cup of tea!!! Highly recommend this service to anyone who wants to ensure the health and safety of their solar system — and all for FREE! A top-notch company that does exactly what they say they are going to do no catches very impressed

Scam. Cold called an elderly family member offering a free check up for his solar panels. When I called them to cancel the appointment he had been bullied into they couldn't wait to get me off the phone. Avoid.
