Can anyone help please? My parents have been having their bungalow refurbished for the last 9 weeks (been living with me). Due to move back Saturday. They've had new radiators fitted and the old room thermostat has been taken down. They had a gas safe plumber booked to come yesterday to install new thermostat and get the heating up and running but he postponed to today and has now let them down completely. My dad is unwell and can't move in with no heating. Can anyone recommend a gas safe plumber that might be able to help today or tomorrow please?
