It was a great job. The Workmen were neat, tidy, quick and professional and loved a wee cup of tea. Heat in the house is fantastic. We only need it on for half an hour and the house is lovely and warm . Many thanks to energystore.

Absolutely brilliant. I can come into the house at anytime of the day now and the house will be warm and cosy. The heat doesn't need to be on for long and it holds the heat from the previous time. Really appreciated the work and a big thank you to energystore.

Job couldn't have been better. Only problem now is the house is so warm and cosy, then you go outside and its freezing. I would recommend energystore to everyone!.

Is my house suitable for CWI?

If your wall has a cavity it may be suitable if there is at least a 40mm gap in the cavity, the cavity is free from debris and the walls have been well maintained.

How long will it take to install CWI?

It usually takes our trained operatives around two hours on site to complete an installation but, it can take longer for large houses.

How much will I save on heating?

The amount saved on your heating bill depends on the size of your house and heating type but, typical homes can save up to £250 a year.

Are there grants available?

"There had been a lot of damp in the rooms and a smell in the house. It was quite hard to heat, making it an uncomfortable home. The house is warm now, no sign of damp and we're looking forward to seeing a difference in our fuel bills."
