What Our Customers Say

  • From the start I was convinced they were the right company for me and the price was right and the whole experience was exceptional. I’ve saved a lot on my energy bills already.

    Mrs Maginn, Antrim
  • I contacted 3 companies about insulating my home; two tried to talk me out of it. Only CosyInsulation said it was possible. I was very impressed by their professionalism.

    Mrs Newman, Draperstown
  • Damp was a real problem in our attic but that all changed. The surveyor knew everything. The benefit to the entire house is massive! An excellent experience overall.
