Heat pump fitted by ohm energy in November 23 to replace a lpg boiler. Survey and quote was efficient and reasonable. Adjustments to quote for radiators and other bits done easily and at a competitive price. The heating engineers fitting the system were excellent. They were tidy, polite and well organised. Cannot fault their time in our house. We were left with a warm house and plenty of hot water. Excellent company to deal with from start to finish.

Professional, polite, helpful and friendly. Turned up on time, and go the job done. They installed my system about 10 years ago, and have maintained it superbly well in all that time. We had a rare breakdown recently, they got part of the system going, offered us a temporary solution, and came back and fixed it as soon as the parts were in. Well done - couldn't ask for more.

OHM were very efficient in installing our system back in 2015. We had an issue with a panel and the Chinese supplier was not helpful in not honouring the warranty. We did however eventually get it sorted and OHM kindly offered money towards the purchase of a new panel as goodwill. Thank you for finally allowing this to be resolved amicably.

Very impressed with this company. From planning all the way to installation, they have been very understanding of my questions and they have made the whole process exciting and hassle free. The installation process was straightforward and the guys were very tidy with minimal disruption to our lives. I’m delighted with what has been achieved and look forward to working with them on other projects in the future. I highly recommend Ohm Energy.

OHM fitted a heat pump in my three bedroom house in July 2022. They have been professional and reliable from first contact to the annual service, carried out in July 2023. OHM specialises in renewable energy, including heat pumps. I'd recommend a specialist when considering getting a heat pump because they're not yet common in the UK and it's best to have an experienced company involved. Highly recommended.

I can’t speak too highly of Keith, engineer at OHM energy, who came and fixed our air source heat pump which broke down during freezing weather. The problem turned out to be complex, Keith came out to us three days in a row and with immense patience and perseverance he diagnosed and fixed it. He even phoned me on the fourth day to check all was well, which it was. A shout out too to Ryan in the office who was extremely attentive and responsive to our cries for help.
