Heating & Boiler Engineers in Buckinghamshire
Family-run, Gas Safe & OFTEC registered heating and air-conditioning engineers, based in High Wycombe and serving the whole of Buckinghamshire.
Local heating engineers you can trust
Buckinghamshire is our home. Smith's Heating Services has been based at Derehams Lane in High Wycombe since 2003, looking after homes and businesses across the county.
From a new boiler in Aylesbury to a full central heating system in Beaconsfield, an air source heat pump near Amersham or air conditioning in Marlow, our engineers know the area, the housing stock and the local network of installers and suppliers. Being just down the road keeps our travel times short and means we can respond quickly when something goes wrong.
Over 90% of our work comes from referrals — neighbours, friends and family recommending us to one another. We believe correct installation is the single most important thing, and the job is not finished until the paperwork is done.
