If your Grant boiler should fail during the first 2 or 5 years, please feel free to contact Grant Engineering's Service Department on 01380 736920 directly or search for a Grant approved engineer using the link above and advise them the boiler is still under manufacturer's warranty.

  • The appliance has not bee commissioned or serviced in accordance with the installation and servicing manual
  • Problems caused by lack of oil or faults with the oil supply system
  • Tampering
  • Freezing
  • The flue system has been incorrectly fitted or does not meet the installation requirements
