Vaillant boiler repair

Vaillant can offer you a choice of two repair options. We'll send one of our own Vaillant trained engineers out and get your boiler working again.

The Repair & Protect plan is designed for broken boilers that aren't within their manufacturer's guarantee. Provided by Domestic & General, Repair & Protect boiler protection gives you approved and unlimited repairs for the duration of your plan, and if we can't fix it on the initial visit, you won't pay a penny.

The fixed price repair option is a one-off package designed for broken boilers that aren't within their manufacturer's guarantee.

Every repair includes a gas safety check.
