Thermocouple

We stock a wide range of thermocouples for gas boiler spares, including genuine and compatible parts for Baxi, Glow-worm and Ariston. Our range covers common replacements for both permanent and interrupted pilot flame thermocouples, with various lead lengths and thread sizes. If you are unsure which thermocouple fits your appliance, our technical team can check the fitment against your boiler make and model. In-stock orders placed by 4pm Mon–Fri (10:30am Sat) are despatched the same day. You can also visit our Doncaster trade counter for advice and immediate collection. We offer 30-day returns on most items, and our range includes OEM, compatible, refurbished and obsolete parts where available.
