Glasgow's heating work is shaped by the housing. Tenement flats often run compact boilers, share stair pipework and have neighbours below who feel a leak first. Bearsden and East Kilbride houses carry bigger systems, cylinders and more bathrooms.
Winters are cold, wet and dark, and the first hard frost or a week of rain reliably produces a spike of boiler and leak calls. Drive time matters more than distance.
Clydebank and Paisley are reachable from a west-side base, but Hamilton and East Kilbride sit south and east of the city, where a rush-hour job can cost half a day. Gas work needs Gas Safe registration, which customers can check, so it belongs on the page.
Electrical proof such as NICEIC belongs there too, if you hold it.
