What CET does

CET LTD Chingford is a UK-based boiler spare parts and repair specialist founded in 1994, operating as a private limited company headquartered in Chingford, London. The company sells new, compatible, and reconditioned combi boiler components—including printed circuit boards (PCBs), diverter valves, fans, heat exchangers, pumps, expansion vessels, electrodes, sensors, and repair kits—across more than 40 boiler manufacturers such as Worcester Bosch, Vaillant, Baxi, Potterton, Vokera, Ideal, Glowworm, and Ariston. CET's core technical capability centers on PCB reverse engineering and remanufacturing, with qualified engineers independently and repeatedly testing PCBs, diverter valves, and fans, including soak testing to Gas Council standards; the company also offers hand-cleaned, reconditioned components and pumps/heat exchangers remanufactured to meet new-product performance benchmarks.

CET runs a direct-to-consumer e-commerce model through cetltd.co.uk, with next-day UK delivery for orders placed before 3pm Monday to Friday and a flat £12.00 delivery charge. Revenue is generated through one-time parts sales (PCBs priced £60–£150, fans £60–£114, valves £12–£90, pumps £84–£180, sensors £5.50–£54), a repair and exchange service where customers receive refurbished replacement units in return for old cores within a 7-day window, and sales of reconditioned products carrying a 12-month warranty against faulty workmanship. Primary customer segments are UK residential homeowners with combi boilers and independent heating engineers and plumbers procuring parts for client work, with a secondary segment of commercial and large-building operators using PCB redesign services to extend the life of older heating systems. The company operates from a single UK site and currently serves only the domestic UK market.
