“After having trouble with a 10 year old boiler I asked Ricky and Adam to check it and unfortunately it was in a bit of a state so a new boiler was required, they ordered one immediately and installation was done in 2 days. The workmanship was 1st class because they changed all the old piping and left everything clean and tidy. Highly recommended.”
