Rewiring and Electrical Safety Audit

Locate and label the consumer unit (fuse box)

Find the main switch, RCDs/GFCIs and any circuit labels before testing.

Inspect the consumer unit for scorch marks, damp or loose wiring

Look and smell for burn marks, corrosion, or water ingress.

Test each RCD/GFCI breaker using its built-in test button

Press 'Test' — the protected circuits should cut power; then reset.

Verify socket RCD/GFCI operation with a plug-in tester

Use a tester at multiple sockets to confirm trip/reset behavior.

Visually inspect sockets and switches for cracks or heat marks

Check faceplates, burn stains and secure mounting.

Gently test plugs for loose contacts (unplug first)

With power off, wiggle plugs to check for looseness or movement.

Inspect extension leads and power strips for frayed cable or DIY repairs

Discard or replace leads with exposed conductors or poor fixes.

Count devices on each extension lead and compare with its rating

Unplug excess loads; never daisy-chain multiple extension leads.

Inspect portable appliances for damaged cords or exposed wiring

Look for frays, missing earth pins, scorch marks or loose plugs.

Tag appliances that need PAT testing and schedule it where required

Record items needing formal PAT tests (workplace or high-risk devices).

Test smoke and carbon monoxide detectors; replace batteries and note dates

Press each unit's test button; replace batteries yearly or as needed.

Check for warm outlets, flickering lights, or breakers tripping under normal load

These signs can indicate overloads or loose connections.

Inspect visible wiring for DIY splices, exposed conductors or improper routing

Do not touch exposed wires; document locations and condition.

Record findings, label circuits and note dates for future audits

Keep a short report with issues, corrective actions and test dates.

Call a licensed electrician if you find red flags

Red flags: burning smell, sparks, repeated breaker/RCD trips, exposed wiring or a damp consumer unit.
