Commercial-grade fixed wire testing across the permanent installation — distribution boards, cabling and terminations verified to BS 7671 Part 6.
Testing arranged around production lines, trading hours or occupied premises rather than forcing a shutdown.
Multi-floor or multi-unit sites can be tested in phases so no single day loses full power.
Circuit schedules and test results delivered as a complete pack, not just a pass/fail summary.

5 years for most commercial premises, shorter for higher-risk environments like industrial or agricultural sites.

Any C1 (danger present), C2 (potentially dangerous) or FI (further investigation) observation makes the report unsatisfactory.
