Unsure if your Worcester Bosch products are still under guarantee? Simply enter your 23 digit serial number below to find your guarantee expiry date.

Please be aware that all dates and guarantee validity of boilers are subject to an annual service being undertaken every year since installation, as outlined in the Guarantee Terms & Conditions.

How do I find my product's serial number?

Different products have their serial numbers in different places.

You should never remove any screws to try and find the serial number. Also consider your safety and do not look for a data label if your appliance has been installed with restricted access or requires steps or ladders to reach.
