Electrical

Sockets, lighting, consumer units and EV charging — what's safe to do yourself under UK regulations, and what legally isn't.

This section explains UK household electrics in plain English, from identifying wire colours and resetting an RCD socket to diagnosing why a circuit breaker keeps tripping or an LED bulb flickers. You'll find room-by-room lighting guidance covering lumens and layered lighting, comparisons like GFCI versus AFCI (RCD versus AFDD) and aluminium versus copper wiring, plus straightforward walkthroughs for replacing a light switch, socket or fixture safely.

Every article draws the Part P line clearly, showing exactly which jobs a competent homeowner can do and which legally require a registered electrician, backed by current UK pricing for rewiring, consumer unit upgrades and EV charger installation. Content is checked against UK wiring regulations and written with input from qualified electrical tradespeople, so whether you're troubleshooting a dead socket or scoping a full panel upgrade, the advice reflects real UK practice rather than generic guidance.
