Brilliant job. I had a heat pumps solar panels and a battery installed. The tradesmen were so good. I highly recommend this company. Thank you so much

We had an air source heating install done by GRM Energy, the team was professional, hard working and very approachable throughout the install. I have been contacted twice by GRM energy since to confirm that all is working as should. I would have no hesitation in recommending GRM Energy for any install you may require. D. Rees

From first conversation to having solar panels on my roof was only 3-4 weeks! The company is super efficient and I am delighted with the results. Here's to cheaper energy bills. HH West sussex
