About Us

We specialise in sales, calibration, hire and repair of electrical test equipment and associated products.

Initially based in Weybridge we first opened for business in 1997, after two years of steady growth we acquired the assets of Capital Calibration based in Clapham. After a short spell of running from two locations it was decided to merge and run both businesses from the Weybridge office. The facility has since moved to Wimbledon, London where it continues to operate today.

SIS then expanded to East Anglia and sited Norwich as it's new head office and central distribution hub. After relocating to a larger premises in 2013 we are now the best facilitated test equipment supplier in the region. Extensive stock holding, purpose built laborotory and first class sales and administration team put us head and shoulders above other distributors.

Our further expansion north into West Bromwich, Birmingam in 2014 poised us perfectly to be able to service and distribute test equipment not only throughout the UK but also exporting to all parts of the globe.

Specialist Instrument Services is now amongst the UKs leading suppliers of test equipment and associated services. We undoubtedly carry stock in excess of the industry norm and this, coupled with our extensive knowledge and expertise in the servicing of equipment helps to maintain our reputation as a quality supplier to trade and industry.
