Thank you for choosing a new Vaillant boiler, which is one of the best engineered and most reliable boilers on the market today.

During the first year from installation the warranty covers the boiler against manufacturing defects for both parts and labour.

In order to extend this warranty to the second year (ecoTEC plus and exclusive models only), or third year (ecoTEC exclusive only), from installation all you have to do is ensure that the boiler receives a service when it is a year old (for the three year warranty on an ecoTEC exclusive, the boiler must be serviced when the boiler is 1 and 2 years old).

Please note that the cost of the service is not included in the guarantee.

The boiler must be serviced either by Vaillant Ltd. or another competent servicing company (Gas Safe registered) within one year of the installation date and the details recorded in the Benchmark logbook. 

To qualify for for your warranty please either:

- Complete and return the guarantee card, found in the boiler, within 30 days of the boiler being installed.

- Call the Vaillant warranty department on 0800 073 2141 to activate your warranty by phone.

Online warranty registration is currently in development and will be on the Vaillant website shortly.
