About TISS Electrical
TISS Electrical carries out PAT Testing (ITEE), fixed wire testing (EICR), emergency lighting testing and RCD testing for commercial and industrial sites across the UK. We deploy coordinated teams of up to 20 engineers from our offices in Chelmsford, Cambridge, Ipswich and Sheffield, handling everything from small single site visits to large projects with 250,000+ tests. Bluetooth data logging is included on every job and every report comes with photographic evidence of any failed items.
