How do I keep my warranty valid?

Make sure you have your boiler serviced at least once a year.

Your manufacturer will be able to service it for you, or we're happy to.

Who is the warranty covered by?

Your 10 year warranty is covered by Worcester Bosch for up to 10 years.

What does my warranty cover?

Your warranty covers everything that BOXT has supplied and installed for you. That usually means the boiler, flue and any attachments.

Do I need to activate my warranty?

No. We'll register you with the manufacturer as soon as you've checked out your BOXT. So you'll be covered by warranty from the moment your boiler is up and running.

Is my filter covered by warranty?

Yes – your filter is covered by a warranty backed by the filter manufacturer. The length of the filter warranty will always match or exceed the length of the boiler warranty.
