I was very sceptical about using the ECO 3 scheme as I feared it was a scam and I would end up with a big bill or an unfinished or badly done job. However my fears have been proved to be utterly false. This company and all its contractors have been honest, committed and hard working and have made my home a lot more comfortable and I am very grateful to everyone involved .

These boys are seriously good

These boys are seriously good. If you want the best, use these, you won’t get better treatment and workmanship, and they leave everything scrupulously clean and tidy. You can’t go wrong with stellar energy.

Very happy with the work completed.

Stellarenergy organised an eco friendly grant funded improvements for my home (loft and wall insulation plus storage heaters). The workmen doing the work were very efficient and friendly. I am very happy with Simon (who took the lead) and the work completed.

Stellar were upgrading our loft insolation. I had a phone call in the morning to say they would be arriving earlier than arranged. The guys were friendly & completed their work quickly. They explained what they had done. They cleaned & hoovered the area before leaving.

Not sure about the one star rating given by the other person?!? But the lads did good on my job. Not a nice job up there, not easy at all.
Cleaned after themselves too.
Many thanks, much appreciated!

Came today to do my loft it was left in a dreadful state where i needed a crawl board to even get into loft. They just throw my things like 2 Xmas trees and decorations where i have no hope of getting them. They placed up 3 notices on my loft to say i needed a broad yet they could not tell me this at the start or even when they finished it looked as it was done slap dash. not impressed in fact as i am old and have no help at all i think its very unfair. Since than i am pleased to say they have corrected my loft got my things within reach. So i have updated my review. They have also placed some wood for a walk though for me. so i thank them

Hi Mrs Willoughby. Thank you for bringing this to our attention. I would agree that this is not acceptable, and falls far below the standard Stellar Energy expects of itself and it's agents. Please accept our most sincere apologies. I will contact you today to make arrangements to have this issue rectified.
