  We had solar panels removed around make space for a velux window. The initial quote was £476, with reassurance that if the work took longer it would only be “slightly more”. However, the final bill came in at almost double this amount, and we were not contacted on the day to advise that costs were escalating or to seek approval before the work was completed. That said, communication during the dispute itself was polite and professional, and once we raised our concerns the company did engage constructively. They acknowledged that the wording used in the estimate was unhelpful and ultimately agreed to a reduced and more reasonable final price, which we appreciated. The work itself was completed, and while we were unhappy with how the pricing was handled initially, we were pleased that the matter was resolved amicably in the end. Clearer communication around estimates and cost overruns would significantly improve the experience.

  A very positive experience. OHM installed an Air Source Heat Pump in May 2025. The whole process from initial survey to completion was friendly, professional and efficient. We are very happy with the quality of the work and would recommend OHM to anyone considering a heat pump.

  A challenging task was tackled expertly by this company. The team of Russell, Simon, Henry, Gino, Adam, and Josh were cheerful and skilled in replacing all the radiators, siting the pump and squeezing the cylinder into a small space. A new shower was fitted very neatly. Everything is now in place and working. It's too soon to tell if the system will cope with cold weather, but so far so good. I can recommend OHM Energy as a heat pump installer.

  I needed my air source heat pump serviced here in Crowborough. I couldn’t find a reliable engineer locally so I contacted OHM energy.The office staff were very helpful and positive.The engineer from OHM knew what he was doing, polite and on time. From initial phone call to job done, was within a week. I will use annually from now on..Very satisfied .

  OHM Energy were called to investigate my hot water not heating up to temp. They charged me £305 never fixed the problem and gave me completely false information, which I assume to justify their charges. They said I needed to change a 3 way port valve which cost me another £280. All a load of rubbish. Called a local plumber, who reverted back to the OLD 3 way port valve as nothing wrong with it and found the actual issue which was a simple hot water leak. They company will claim my system is "complicated", I would suggest to OHM Energy if it is "complicated" then maybe they should try another business. In addition to that, if you can't find the fault, don't just make things up and incur more cost to your customer. Walk away with your call out charge and be happy. Waste of money.

  OHM fitted an air source heat pump for us- It was a slightly tricky install into a fairly tight space that Octopus energy had said that they couldn't do. They came with the creative thinking required to route the pipework as straight forwardly as possible and fit a slimline cylinder into our smaller space. It was a 4 day job on the heat pump install with an extra day beforehand to upgrade some radiators. All the team were polite, professional and communicative. We are happy with the outcome.

  OHM were amazing. We have a complicated system and it took a while to diagnose our issue, but both Keith and Ryan went above and beyond to resolve in the quickest and most economical way possible. Personable, helpful and very knowledgable. 5 stars

  The OHM team made the design and installation of the underfloor heating and air source pump such an easy thing amongst all the chaos and disruption. All the staff who came on site were so agreeable and pleasant to have around. More than that, if you showed an interest they went out of their way to explain, teach and advise. Highly recommended.

  OHM Energy have supported us through the whole process of getting solar panels on the roof, an air source heat pump combined with underfloor heating throughout the house. After a slightly rocky start which was probably due to us not understanding enough about the product & process everything is now finished & up and running. OHM have been really good to deal with & any issues were dealt with immediately. Thank you OHM! -
