What Are the Key Terms and Conditions for a Glow Worm Boiler Warranty?
The key terms and conditions for a Glow worm boiler warranty include mandatory registration within 30 days of installation, installation and commissioning by a Gas Safe registered engineer with a completed Benchmark checklist, and annual servicing throughout the warranty period. Without timely registration, coverage reverts to just 12 months from installation or manufacture date.
Coverage applies to parts and labour for manufacturing defects only, excluding damage from limescale (without a system filter), misuse, unauthorised repairs, poor water quality, or non-approved modifications. For 10-year terms, a Glow-Worm Power System Filter is essential.
How Do You Register a Glow Worm Boiler Warranty?
You register a Glow worm boiler warranty online via the official Glow-worm homeowner portal or through your myREWARDS/Club Energy installer within 30 days of installation. Provide the full 28-digit serial number, installation date, proof of purchase or Benchmark logbook, and engineer details.
This step activates the full promotional period and generates confirmation for your records, helping landlords demonstrate compliance during gas safety inspections.
What Does a Glow Worm Boiler Warranty Cover?
A Glow worm boiler warranty covers parts and labour for genuine manufacturing faults on core components including the heat exchanger, diverter valve, pump, fan, and printed circuit board during the valid term. Approved claims result in free diagnosis, repair, or replacement, supporting consistent efficiency, lower energy bills, and reduced carbon emissions.
Homeowners gain protection against costly major repairs, while landlords minimise tenant disruptions and maintain regulatory standards.
How Can You Keep Your Glow Worm Boiler Warranty Valid?
You can keep your Glow worm boiler warranty valid by arranging annual Gas Safe servicing that includes full internal inspection, cleaning, pressure testing, magnetic filter maintenance, and verification of system inhibitors.

FAQs
Is a Glow-Worm boiler warranty transferable when selling a property?
Yes, Glow-Worm warranties are usually transferable to new owners if registration is updated and proof of continued annual servicing is supplied—notify Glow-Worm promptly to complete the process.
What warranty applies to Glow-Worm smart controls or accessories?
Glow-Worm controls and accessories typically carry a separate 2-year return-to-base warranty, distinct from the main boiler parts and labour coverage.
Can I extend a Glow-Worm warranty after the initial installation period?
Limited extensions or repair-linked additions may be available on some models—check current options directly with Glow-Worm or consider third-party boiler protection plans.
Does poor water quality automatically invalidate a Glow-Worm warranty?
Limescale or sludge damage from hard water may lead to rejected claims unless preventive measures like the Power System Filter and inhibitors were fitted and maintained.
What happens if the boiler is relocated during the warranty term?
Relocation requires approval from Glow-Worm and must be carried out by a Gas Safe engineer—unauthorised moves usually invalidate the remaining warranty coverage.
