Fuses & Accessories

Reliable electrical protection is a fundamental requirement when installing or servicing domestic and commercial heating systems. Our selection of fuses and electrical accessories covers everything a heating engineer needs to wire boiler controls, circulation pumps, and motorised valves safely. Carrying a stock of standard cartridge fuses, particularly the 3A variants required for most domestic boiler fused spurs, is essential for rapid breakdown repairs and routine maintenance. We also provide a variety of terminal blocks, inline fuse holders, and wiring accessories designed to handle the thermal and electrical demands of modern plant rooms and airing cupboards. Using high-quality and correctly rated electrical spares ensures that every circuit remains fully protected against overloads, keeping the installation compliant with current IET Wiring Regulations while safeguarding expensive boiler components from electrical damage.
