BIOTECH MECHANICAL LIMITED

Highly recommended! This team clearly cares about doing excellent work and leaving their customers satisfied. We recently had a solar PV and battery system installed and couldn't be happier with the result. Paul came out and spent considerable time on the initial survey, carefully assessing our needs and recommending 21 panels though we reduced to 19 panels to cut costs, he was supportive of our decision and it's proven to be exactly the right call for our situation. Brad and Max delivered exceptional workmanship and were genuinely friendly and professional throughout the entire process. What really impressed us was their willingness to tackle the challenging cable routing through our floorboards and loft into the garage without a single complaint—they simply got on with it and did it properly. Max's commissioning of the battery was invaluable too, taking time to ensure we understood how the system works, particularly the important detail that maintaining at least 15% charge is crucial for full home backup since we got the SigEnergy gateway. As newcomers to solar, we've been delighted to discover we're generating electricity even in October—something that genuinely surprised us! It's already clear we're saving money, and that's been incredibly rewarding to see.

Richard and his team did a fantastic job installing 12 panels on 3 aspects together with a Sigenergy battery/inverter despite the rain and cold temperatures of November. It's not easy choosing a solar installer and I would have no hesitation in recommending Biotech Renewables.

I highly recommend Biotech Renewables. The team did a great job installing 14 panels and a Tesla Powerwall 3 battery over 2 days last week as part of their partnership with Heatable. All very straightforward and minimal intrusion. The system started capturing the sun's energy straightaway and I should be able to start exporting to Octopus in a few weeks time once they install the Smartmeter.

I can highly recommend Max, Matt, Richard and Paul at Biotech Renewables, they installed a Tesla Powerwall 3 and Zappi EV Charger. This was complicated by being one of the first PW3s without a Gateway. The team came through without fuss and worked efficiently and reliably. Now I'm benefiting from running my home on cheap Octopus overnight rates and utilising my solar PV to significantly reduce my electric costs from £3/day to less than £1. Excellent work by a trusted team.

I recently had 19 solar panels and a Tesla Powerwall 3 installed by Richard, Paul, and the team at Biotech Renewables, and I couldn't be more pleased with the experience. From the outset, their pricing was very competitive compared to other installers I approached. What truly set them apart, though, was their understanding of my specific requirements. I wanted the battery installed inside my garage, which involved digging a small trench. The team carried this out neatly and efficiently, without charging anything extra, which was a refreshing display of integrity and customer focus. Communication was another strong point — every step of the process was handled with prompt and clear updates. Biotech managed all the necessary approvals, including the G99 application, with complete professionalism. Although there was a delay from the DNO, Biotech Renewables ensured the installation went ahead immediately after approvals came through, without any unnecessary waiting. Post-installation, I noticed a small scratch on one of the panels, and they arranged for a replacement within just 3 days — no hassle, no pushback, just a quick resolution. If you're planning to install solar panels — whether or not you're adding a battery — I highly recommend Biotech Renewables. Their workmanship, customer service, and transparency are truly top-tier.

Great solar and battery installation

Biotech Renewables were the installer for a solar panel and battery system we purchased through Heatable. We wanted to give them a review. Richard and the team were great. Richard conducted the pre-install site visit. Nothing was too much problem and as solar novices he ran through all the details with us. Their installation team were great. They started and finished a day early, even going as far as swapping some broken roof tiles with good ones they took out during the installation. Finish on all the work is really smart and neat.
