Heating & cooling, done properly
From a straightforward boiler swap to a full air source heat pump or multi-room air conditioning system, everything we fit is installed and maintained by our own Gas Safe & OFTEC registered engineers across High Wycombe and the surrounding areas.
One local team for your whole system
Smith’s Heating Services is a family-run firm of heating, plumbing and air-conditioning engineers. We’ve been a Worcester Bosch Accredited Installer since 2003, and over 90% of our work comes from referrals — so we take the same care on a service call as we do on a full installation.
Whatever you need, you’ll deal with the same trusted team from survey through to commissioning — and, as we like to say, the job is not finished until the paperwork is done.
