Always a fantastic service
Steve installed a new Baxi boiler at my home this week and, as always, provided an excellent service. Nothing is too much trouble, he always explains the process in full, does a fantastic job and leaves everything clean and tidy. I'm chuffed with my new boiler and wouldn't hesitate to recommend Steve for any work to be carried out.Verified reviewerJob location: SA410 Gas Safety Checks - CP12
