How Much Does Electrical Installation in London Cost? A Complete Guide

When planning electrical installation in London, understanding the cost is vital to budgeting and avoiding surprises. From hourly rates to full rewires, this guide breaks down typical prices, factors influencing costs, and tips for hiring the right electrician.

Typical Hourly and Day Rates for Electrical Installation in London

When it comes to electrical installation in London, understanding hourly and daily rates helps you plan your budget and avoid surprise charges. Most London electricians charge between £40 and £60 per hour during standard business hours (usually 8 am to 6 pm, Monday to Friday). These rates apply to smaller jobs like installing a new light fitting, replacing a socket, or conducting safety checks. However, for emergency work, evenings, or weekends, rates increase significantly—often ranging between £80 and £100 per hour, sometimes higher depending on availability and urgency.

Daily rates are another common pricing model for larger jobs. For example, full-day bookings for consumer unit upgrades or partial rewiring projects typically cost between £370 and £575 per day. This option can be more economical for clients with multiple tasks, as it avoids separate call-out fees.

London ELEC, a trusted service provider, notes that their rates include full compliance with BS 7671 regulations, the latest testing equipment, and NICEIC-certified electricians. It’s important to clarify if quoted rates include VAT, materials, or testing and certification. Transparent quotes and a breakdown of costs help ensure that you're not paying more than necessary—and that your installation is legally compliant and safe.

Electricians in London typically charge between £40 and £60 per hour for standard work. Emergency or out‑of‑hours jobs can reach £80 to £100 per hour.

 For full‑day projects, London firms charge between £370 and £575 per day.

Here’s a breakdown:

• Standard onsite visit (8 am–6 pm weekdays): £45–£60/hr Full‑day fixed‑price (8 am–5 pm): £370–£575
• Emergency/out‑of‑hours: £80–£100+ per hour

London ELEC notes that large projects—EV charger installation, full rewires, or consumer‑unit upgrades—are often quoted at a day rate or bundle price rather than hourly.

Project Type: What You'll Likely Pay

The cost of electrical installation in London depends heavily on the type of project you need. Small tasks like installing new sockets, upgrading light fixtures, or fitting a cooker point are generally affordable. For instance, a basic single socket installation may cost around £60–£80, while fitting a new ceiling light or pendant light can range from £60 to £120, depending on complexity and accessibility. Tasks such as installing an extractor fan in a bathroom may be quoted at around £220, including basic parts.

For medium-sized projects, such as replacing an old fuse box or consumer unit, prices range from £450 to £780, depending on the property’s size and whether full testing and certification are included. A proper installation will include RCD protection, surge protection, and a full inspection of existing circuits to ensure compatibility and safety.

Large-scale projects like a full rewire are the most expensive. A 2-bedroom flat might cost around £3,100–£3,500, while a 3-bedroom house could range from £4,000 to £8,000, depending on layout and material costs. London ELEC advises factoring in the cost of plastering or redecorating after rewiring, which isn’t usually included in the electrical quote. All work is certified under Part P of the Building Regulations and BS 7671, ensuring both safety and compliance with legal standards.
