DIY electrical work vs when you need a professional
Under Part P of the Building Regulations, certain electrical work in a home is notifiable — it has to be carried out by a registered electrician who can self-certify it, or separately inspected by your council's building control. New circuits, consumer unit replacements, and any new work in a kitchen or bathroom are notifiable. Like-for-like socket or switch swaps usually aren't.
Satisfaction and aftercare — support beyond the job
A registered electrician's paperwork doesn't end when the job does — you should receive a Building Regulations compliance certificate (for notifiable work) or an Electrical Installation Certificate, which you'll need if you sell the property or make an insurance claim. Keep this with your household paperwork.
Common electrical myths, busted
"If it's not broken, the wiring's fine" — wiring can be dangerous long before it visibly fails. "Any handyman can do electrics if it's small" — scope, not size, determines whether work is notifiable. "A tripped RCD means the RCD is faulty" — usually it means something else on that circuit is, and the RCD is working as intended.
What affects the cost
Cost depends on the scope of the job, how much of the property needs to be accessed, the age and condition of the existing wiring, and whether the consumer unit needs upgrading. A single socket replacement is quick and low-cost; a full rewire in an older property takes longer, partly because of the making-good work afterwards.
What a good electrical quote should include
A proper quote should state the scope of work, whether it's notifiable under Part P, an itemised breakdown of labour vs materials, the certificate you'll receive on completion, and how long the job is expected to take. If a quote is missing any of these, ask before agreeing to the work.
New build and extension electrical work
Wiring an extension or new build from scratch is different from rewiring an existing room — it's planned around final wall positions and fittings before plastering, so timing with your builder matters. First-fix electrical work (cabling inside walls) has to happen before plastering; second-fix (sockets, switches, fittings) after.
Common electrical jobs
Electricians handle everything from minor repairs to full rewires: replacing a consumer unit to meet current wiring regulations, adding or moving sockets and light switches, installing an EV charging point, fixing faults such as tripping breakers or flickering lights, and full or partial rewires in older properties.
Electrical emergencies — what to do
If you smell burning, see sparks, or a breaker keeps tripping and won't reset, turn off the affected circuit and call an electrician. Don't reset a tripped breaker more than once if it trips again immediately — that usually means a fault, not a one-off.
