Tripping fuses or flickering lights? Common causes
A breaker that trips repeatedly usually means a fault on a specific circuit, not the consumer unit itself — an electrician can isolate which circuit is affected. Flickering lights are often a loose connection rather than a faulty bulb, and worth having checked rather than ignored, particularly in older wiring.
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.
Understanding the labour vs materials split
Materials — consumer units, cabling, sockets, fittings — are usually a smaller share of an electrical quote than labour, particularly for jobs involving lifting floors or chasing walls. If a quote seems unusually cheap, check whether it's using a lower-spec consumer unit or cabling than a competing quote, not just a lower labour rate.
What is an EICR and do I need one?
An Electrical Installation Condition Report checks a property's wiring against current safety standards and flags anything worn, damaged or non-compliant. Landlords are legally required to get one every 5 years; homeowners aren't, but it's worth having on an older property or one you've just bought where the wiring history is unknown.
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.
Three steps to hiring the right electrician
First, confirm they're registered with NICEIC or NAPIT and ask to see their registration number. Second, get a written quote that itemises labour and materials separately, not just a total. Third, ask what certificate you'll receive when the work's done — for notifiable work, you're entitled to a Building Regulations compliance certificate.
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.
How long does electrical work take?
A socket or switch swap is usually under an hour. A consumer unit replacement is typically a full day, often with the power off for several hours. A full rewire in an occupied property commonly takes 5 to 10 days depending on size and access, plus time afterwards for plastering and redecorating that isn't part of the electrical work itself.
