Where to buy Grant in the UK
Grant sells through a mixture of authorised distributors, specialist trade merchants, and independent engineering factors.

How to identify genuine Grant products
Genuine Grant parts carry a moulded or stamped manufacturer mark, a traceable serial or batch number, and the appropriate regional compliance mark (UKCA for UK-only, CE where still accepted). Counterfeit parts are a known issue in the heating market: they may look correct externally but often fail under load or at temperature. If you're sourcing through an independent reseller, ask for the manufacturer's batch certificate, particularly for pressure-rated, safety-critical, or nuclear applications.
