Why Annual Servicing Matters

Most boiler manufacturers require an annual service by a Gas Safe registered engineer to keep your warranty valid. Skipping a service can void your cover entirely.

Regular servicing improves efficiency, reduces your gas bills, and catches faults before they become costly breakdowns — especially important heading into winter.

Our engineers service all major brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann and more.
