New boiler installation and air source heat pumps in Ottery St Mary, Devon — Gas Safe registered, fixed price, all major brands fitted.
Ottery St Mary is one of the older market towns in Devon, its boundaries set as far back as Edward the Confessor's reign and its parish church so grand it's sometimes called "Exeter Cathedral in miniature." It's best known now for the Tar Barrels. Every 5 November, runners carry blazing barrels of tar through the town's narrow streets, a tradition that's been going for centuries. That mix of tight medieval streets and later Georgian and Victorian infill makes for varied housing, and the survey matters more than the postcode when it comes to sizing a boiler.
SWW installs and replaces boilers in Ottery St Mary and the surrounding villages, all by Gas Safe registered engineers. We fit Ideal, Vaillant, Worcester Bosch, Baxi and the other major brands, and size the job to the actual property rather than the easiest option. We also install air source heat pumps under an MCS umbrella scheme, with the £7,500 Boiler Upgrade Scheme grant applied. See our Devon heat pump page for the detail.
