Custom Renewables installed a battery system for us. The project was managed by Liam and the installation was carried out by Justin. The work was done well and very efficiently. Everything was left neat and tidy at the end. Custom Renewables provide a very good service.

Great people and very tidy job. Liam and his team replaced an old ground source heat pump with an up to date version taking care to find something appropriate to deliver the heating needed but still fit in the limited space of the old one. They dealt with the whole process whilst we were away and we returned to a nice tidy job with a new efficient boiler and a follow up visit to make sure we knew how to work it. It’s been great and all efforts were much appreciated. Sarah & Ivan

Having recently moved house I was looking to install a new solar system as I left one behind in the old house. Some challenges faced were poor support the day after the system was installed, lack of MCS certificate making sale of the house a problem, some wiring issues my electrician spotted on a visit some months later (I had him fix it). So looking to spend a pile of money and concerned about a repeat – finding someone who would do the job PROPERLY was paramount. I did not want to throw a ton of money at people who would just slap something into place, and I’d never see them again. I had Custom Renewables shortlisted for a heat pump install as their reviews were exceptionally good and pictures of their work showed high quality installations and finishes. I had separate quotes for air conditioning and solar installations but once speaking to Mark he indicated they undertook whole renewable projects including solar and air conditioning. He quoted as a total project which was decently priced vs my separate quotes from my shortlisted suppliers. He took the time to visit the house multiple times to ensure he clearly understood my requirements, offered advice on hot water cylinder relocation, aircon setup and unit locations (whole house), heat pump and pipe run considerations and some other minor plumbing support (sink change, fixed water pressure to house, shower re silicon etc). This was a large project with various trade specialities. Neil, Garry, Harry you guys were superb – looked after my home and concerns with consideration. Performed a top-notch install and debated all my ideas and plans and offered advice where I was maybe going a little too far left field 😊. Everything just works. Heat pump has house exactly how we want it, aircon’s (not used much yet as it is cold) are all working with Alexa integration for automatic on off as well as app control should we wish to turn on whilst out of the house. Solar (33 panels) is generating a ton of electricity across 4 roofs and 4 MPPT’s paired with a 45kw Sigenergy Battery. I have received my DNO export for full 12kw inverter value. The early maths is showing that I will very likely achieve a net zero cost for the year or potentially a small profit Gas has been disconnected and not missed. Custom renewables also installed an EV-Charger and I have managed to fill up the car battery a number of times purely on solar power. This review is a couple of months late (DIY has been keeping us busy) and I can report that everything is still working perfectly, I have no regrets. I have had the odd question and Mark from custom renewables has always been there to respond. He has also checked in a few times to ensure we are satisfied. I can highly recommend Custom renewables for Heat Pumps, Solar and Airconditioning.

Mark and the team were professional throughout. A number of visits to our house to check all the work that was required prior to the installation, all prep work done on time and the installation also done as planned and on time. All works were done with minimal intrusion and at all stages the house was left clean and tidy. Follow-up visits have been completed to ensure the installation is working as expected and all waste was tidied up within a day or two. Thoroughly recommend.

I found Mark and the team via Heat Geek's Elite Installer listing after being disillusioned by multiple MCS-certified installers who proposed oversized heat pumps (2 x 15kW in one case) without considering anything beyond the building's floor area. The team at Custom Renewables employed modern heating engineering processes to design an underfloor heating and domestic hot water system for my new build. The process started with system sizing based on detailed heat-loss and hot water usage calculations for the building. With this, they sized and selected a Viessmann ASHP and the cylinder, then created a plumbing and UFH pipe layout. They used a snail pattern to minimise hot and cold spots on the floor. I had many questions throughout the process, which were always answered promptly and with confidence. The installation, which was done in phases, was conducted in a neat, tidy, and professional manner. As a freebie, Mark even instructed my bathroom plumbers on how best to join MLCP pipework to avoid leaving gaps in the insulation.
