History our team:

  • Members of our team were brought together as the company ASD (Auto Service Diagnostics) in Melksham, Wiltshire by Sykes-Pickavant to develop electronic service tools that complemented their range of handtools.
  • Later Sykes-Pickavant brought the ASD company under its own umbrella to become SP Diagnostics and SP Technology.
  • Sykes-Pickavant was taken over by Facom Tools and the R&D team also started to develop products under the Facom brand.
  • Stanley Tools then took over the Facom business and unfortunately no longer required the diagnostics side of the business. The Sykes-Pickavant brand was sold which kept the brand alive, at the time key members of the diagnostics team kept in touch and were brought back in to the Sykes-Pickavant brand to reform and support the diagnostics side of the business.
  • The R and D side of the business has been sold to SP Diagnostics and now operates completely independently of Sykes-Pickavant, with the aim to grow, improve and expand the automotive & diagnostic offering. SP Diagnostics continues to support existing Sykes-Pickavant diagnostics customers.

Our team has continued to be located in Wiltshire not far from the original site in Melksham.


We support, develop, design and manufacture products at our R&D centre based in the South West of England in Wiltshire, UK

In house facilities:

  • Software and hardware development
  • Custom design of enclosures
  • Manufacturing and testing
  • Technical support & service of products

At SP Diagnostics we feel it is important to support UK based businesses, both as customers and suppliers.

Our aim:

SP Diagnostics are here to innovate in the automotive diagnostic field, by supporting and listening to our customers and providing technology based solutions to ensure their business is efficient and profitable.
