Just had all my insulation, radiators and boiler completed today with Mo and the rest of the team, and these guys were very professional, quick, and couldn’t do enough for us, great service, thank you so much.

We were happy with the insulation that your company did on behalf of Ecoenergyservices.co.uk but not happy that you or them have not responded to emails for you to complete 12 month check or first service.

Worst people to have work on your house mid way through the job they left us high and dry and completely disappeared avoid them at all cost complete scam these people are cowboys and are not fit to work in this industry the money grabbing thiefs.
I have had nothing but bad issues with them, from not answering their phones, not getting back to me, to leaving holes in the floor from putting in the new heating system. They laid loft insulation on top of boxes in the loft, nearly hit my husband with excess insulation as they trow it out of the loft, they got funding for the cavity wall insulation and never completed it, and now I cannot get any other company to do the work. The only good thing is the boiler works even though GasSafe had to get them to come out and rectify the pipes and the radiators work.
The air source heat pump is efficient and quiet. The installation team was fantastic.
The team was incredibly polite and professional. My air source heat pump works perfectly.
The air source heat pump is efficient, but the team didn’t clean up properly after the installation.
A fantastic experience. The team was courteous, and my air source heat pump works brilliantly.
