How to find a qualified electrician in London

Electricians in England must comply with BS 7671 (the IET Wiring Regulations) and any work on a domestic electrical installation must either be carried out or inspected by a person registered with a Part P competent person scheme. The main competent person schemes for domestic electrical work are NICEIC, NAPIT, ELECSA, and SELECT (Scotland only).

Registration with a competent person scheme means the electrician can self-certify their own work by issuing an Electrical Installation Certificate (EIC) or a Minor Works Electrical Installation Certificate without requiring a Local Authority building control inspection. An unregistered electrician can legally do electrical work in England but their work must be inspected and certified by a registered electrician or Building Control — adding cost and delay.

Always ask for certification on completion of any notifiable electrical work. You will need this for buildings insurance purposes and when selling the property. An EIC for a consumer unit replacement or rewire should be provided as standard; if an electrician is reluctant to issue one, this is a serious red flag.

London electrician rates are among the highest in England, reflecting higher operating costs and demand. Standard callout (first hour, London): £80–£150; subsequent hours: £60–£100. Emergency out-of-hours: £150–£250 for the first hour. These rates vary significantly by borough — outer London boroughs (Croydon, Bromley, Enfield) typically charge 15–25% less than inner London.

Common London electrical jobs: consumer unit (fuse board) replacement £400–£700 including certification; full house rewire (3 bedroom semi) £3,500–£6,500; adding a new socket or circuit £120–£300 depending on access; installing an EV charger (single-phase, domestic) £400–£800 including OZEV grant claim if applicable; EICR (Electrical Installation Condition Report) for a 3-bedroom house £150–£280.

Avoid electricians who quote significantly below these ranges for major work. Sub-standard materials, non-certified work, and cutting corners on regulation compliance create fire and shock hazards. For landlords, an EICR is now a legal requirement every five years for all rental properties in England.

For London, where the pool of tradespeople is vast but quality variable, verified reviews are particularly important. Look for electricians with a track record on Yolist, Google, and Checkatrade with specific recent reviews mentioning the type of work you need. A consumer unit replacement by an electrician with twenty reviews mentioning consumer units is more reassuring than a generic "great work" from a plumbing-focused review profile.

Check NICEIC registration at niceic.com/find-a-contractor or NAPIT at napit.org.uk before any work begins. These directories allow you to verify registration by company name or postcode. The registration check takes 30 seconds and confirms the contractor is currently active.

Ask for a written quote (not an estimate) before any work starts. The quote should specify: scope of work, materials to be used (consumer unit brand and specification for fuse board work), total cost including VAT, whether certification is included, and expected completion date. Do not accept "I'll give you a price when I've done it" for any job that can be scoped in advance.
