How long is the Worcester Bosch warranty?
No single term: 5 to 8 yr by boiler model; up to 12 yr with a system filter and an accredited installer (UK).
This is a typical figure, not a guarantee — the term can vary by product line and by country (UK and US terms for the same brand often differ). Always check the paperwork that came with your specific appliance.
