Affiliate Disclosure

BOYLA is free to use. To help cover the cost of researching and maintaining the site, some of our links to parts and services are affiliate links. If you click one and buy something, we may earn a small commission — at no extra cost to you.

This never influences our guidance. We recommend parts and steps based on the fault, not on whether a link earns commission, and our explanations are written independently of any merchant.

The right spare part for your boiler depends on your appliance's GC number (on the data badge), so always check the part matches your specific model before buying.
