How many quotes should you get?
Three is the usual recommendation — enough to spot an outlier (too cheap or too expensive) without asking so many tradespeople to survey your property that it wastes everyone's time. Make sure each quote is for the same scope of work, since a lower price sometimes just means less is included.
Electrical regulations and legal requirements, FAQ
Do I need a certificate for a new socket? Only if it's part of notifiable work such as a new circuit. Can I do my own electrical work? Non-notifiable like-for-like repairs, yes — notifiable work legally needs a registered electrician or council sign-off. What happens if I sell my house without one? It can hold up the sale or affect your buyer's mortgage offer.
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.
Single phase vs three phase supply
Most UK homes run on a single-phase electricity supply, which is enough for typical household use. Larger properties, workshops, or homes adding multiple EV chargers or heavy machinery sometimes need a three-phase supply instead — this is arranged with the network operator, not just your electrician, and can take weeks.
Lighting design and circuit planning
Adding recessed downlights, under-cabinet lighting or dimmer circuits usually means new cabling even if you're keeping the existing consumer unit, since older lighting circuits weren't sized for LED transformers or multiple dimmer switches. Plan lighting changes before, not after, a room's redecorated.
Background checks and identity verification
Before comparing quotes, it's worth checking an electrician's identity and trading history, not just their qualifications — a registration number, a landline or verifiable business address, and reviews that reference specific jobs are all better signals than a mobile number alone.
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.
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.
