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

Make sure you have your boiler serviced at least once a year by a Gas Safe engineer. Learn more about boiler servicing and cover options here. 

Replace. A repair can sometimes be as expensive as a brand new boiler. And you could easily have more problems with a repaired boiler further down the line.
A boiler replacement is usually more efficient and more reliable.
Your new boiler will be covered by warranty too – so if it breaks, the manufacturer will repair it with no extra charge.
We can provide a brand new A-rated boiler from £1,795, or from £25.02 a month with no deposit, including VAT and Gas Safe installation.

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.
