📅 How Often Should I Service My Boiler?
Your boiler should be serviced every 12 months. Annual servicing:
- Keeps your boiler warranty valid (most manufacturers require annual servicing)
- Improves energy efficiency — saving up to 10% on energy bills
- Catches small problems before they become expensive repairs
- Ensures safe operation and carbon monoxide safety
- Is required for landlords alongside the gas safety certificate
Skipping a service can void your boiler warranty. Worcester Bosch, Vaillant and Baxi all require annual servicing to maintain their guarantee.
