What an electrician does
Electricians install, test and repair the fixed wiring and fittings in your home — consumer units, socket circuits, lighting, cooker circuits, electric showers, EV chargers and outdoor power. Notifiable work (new circuits, work in bathrooms and kitchens, consumer unit replacements) must be done by someone registered with a Part P competent person scheme so the work is self-certified for Building Regulations.
Typical prices (UK 2026)
- •New socket or light point: £80–£150 each.
- •Consumer unit replacement: £400–£700.
- •Electric shower installation: £300–£550.
- •EV charger install: £500–£900.
- •Day rate: £180–£350 (higher in London).
Questions to ask and common mistakes
Ask which Part P scheme they are registered with and whether the quote includes the compliance certificate. Common mistakes: using a general handyman for notifiable work (illegal and unsellable), adding too many sockets to an old ring without an RCD, and burying cables in insulation without de-rating the circuit.
- ☐Are you registered with NICEIC, NAPIT or ELECSA?
- ☐Will you issue the Building Regulations compliance certificate?
- ☐Is the quote fixed or an estimate?
- ☐Will you test the circuit and provide an EICR or minor works certificate?
Frequently asked
Can I rewire a socket myself?
Replacing a like-for-like socket faceplate is not notifiable, but any new wiring or circuit work must be certified. If unsure, use a professional.
