Can we fix any Vaillant boiler?
We will repair any eligible Vaillant boiler unless it is uneconomical to do so. In which case, we will provide advice on a suitable product to replace the boiler. If you are a Repair & Care customer and we are not able to repair your boiler or we decide that it is beyond economical repair after the initial repair, Domestic & General will arrange for your boiler to be replaced with a new one, up to the value of £750. Installation and associated costs are not included. Our repair services do not cover larger commercial range of boilers: Vaillant ecoTEC 45kW to 280kW models. Find out more here.
Is my boiler too old to be protected?
You can take out a plan for any boiler less than 8 years old.
Once you have entered into a maintenance plan, this will renew automatically year after year with no cap on the appliance age.
How do I know what kind of boiler I have?
Combination boilers are typically the most popular boiler and are compact with no separate hot water cylinder or cold water storage tank.
System boilers require a separate hot water cylinder (usually found in an airing cupboard), and are usually found in larger homes with multiple bathrooms.
Regular boilers require both a hot water cylinder and cold water storage tank (usually found in the loft), and are usually present in homes with older radiator systems.
If you're still unsure what kind of boiler you have, your local installer will be able to advise you.
