We are TISS Electrical, a nationwide electrical testing and compliance company based in Chelmsford, Essex. Our engineers carry out PAT Testing (ITEE), fixed wire testing (EICR), emergency lighting testing and RCD testing for commercial and industrial sites across the UK.

We work with schools, hospitals, hotels, stadiums and large commercial offices. What sets us apart is our ability to handle volume. We deploy coordinated teams of up to 20 engineers who have worked together for years, giving us the capacity to complete large sites without delays or disruption.

With offices in Chelmsford, Cambridge, Ipswich and Sheffield, we place experienced teams nationwide. Every engineer comes with a full ID pack including qualifications, DBS number and insurance details, so you always know exactly who is on site.
