A Safe Pair of Hands Since 1967

WH Kemp was incorporated on 10 January 1967. Nearly six decades later, we continue to manufacture cable assemblies, wire harnesses, control panels and electro-mechanical assemblies from our purpose-built Wiltshire factory, supporting customers from prototype through to full production.

Every drawing is reviewed with your engineers before production begins, helping ensure that what leaves our factory is exactly what you intended. Around 50 skilled people manufacture to IPC/WHMA-A-620 workmanship standards, combining experienced craftsmanship with disciplined processes that deliver consistent results, full traceability and dependable delivery.

Many of our customer relationships have lasted for decades because customers know exactly what to expect from us.

Rotork plc first sent us a drawing in 1967. They still do.

Relationships like that aren’t built on one exceptional project. They’re earned by delivering the same high standards, day after day, year after year. That’s why customers continue to trust us with new product introductions, production transfers and long-term manufacturing programmes.
