Everything on installation day ran smoothly. Ken kept things on track and made sure the team knew exactly what was happening. The work was done neatly and professionally, and the house was left clean at the end.

We weren’t sure what funding applied, but Ebony explained it clearly and without any pressure. She was easy to speak to and always quick to respond. It made the whole process feel far less daunting.

We added ventilation alongside insulation and it’s made a real difference. Chris explained why it was needed and how it would help. The system was fitted neatly and quietly, with no disruption to the house at all.

Cavity wall insulation was recommended for our house and it’s already paying off. Ali explained what would happen and kept things moving. The team arrived on time, worked efficiently, and left the place spotless afterwards.

Giving a second chance

After a rocky beginning Stellar Energy have done the right thing, accepted thing do and have gone wrong and are doing something about it, using a simple 5 letter word Sorry is not that difficult to say and they have done so, due to a lack of communication I was frustrated regarding my claim for assistance over a period of several months, it has been explained to me that their system failed them and they accept opportunities were sadly missed and things could have been handled a lot better when I reached out to them but again they have fully accepted errors were made. I want to make it very clear I have rewritten my review because Stellar Energy accepted they were at fault and apologized and have assured me they will adapt and improve. I did not accept any financial reward to rewrite this review. After speaking in an open, honest and courteous call from the managing director I will be staying on Stellar Energy books for when grant become available in the future.I do hope the challenges in the future can be overcome by Stellar energy, I am assured what had been a negative experience can be used as learning experience to prevent it happening again, Hopefully all future experiences will be positive ones. Thank you Stellar Energy for doing what was right, Its very much appreciated

Applying for funding seemed daunting until Ali clarified each step. He addressed all our questions and ensured we had everything required. Stellar Energy’s friendly and professional support gave us the confidence to proceed with our home upgrades.

Even with a tight schedule

Even with a tight schedule, Dewey’s team completed our insulation superbly. They worked respectfully, kept our home clean, and delivered excellent results. Our house is already noticeably cosier. Stellar Energy really know their craft.
