We booked an engineer for gas certificate, pipework was incorrect £463 pound later, the gas guy who on the thursday said he would need to do the work before issuing a certificate left on the following tuesday without giving us a gas certificate or invoice. And now they want to charge another £95 per hour + vat for the gas certificate... robbing gits and liars to boot.going to report to business ombudsman and trading standards. So they are asking for more money to check their own work... ummmmmm
