What's Included
- Supply and installation of the socket and back box
- Cable run from the nearest appropriate circuit (for new sockets)
- Testing and certification of the new circuit or alteration (an Electrical Installation Certificate or Minor Works Certificate as appropriate)
- Making good the immediate area around the socket — filling chase channels and patching plasterwork
- Disposal of the old socket and packaging
Factors Affecting Cost
- Whether you are replacing an existing socket or adding a brand-new one. Replacements reuse the existing wiring and back box, keeping the price low. New sockets need cable run from the ring main or consumer unit, which involves chasing walls and lifting floorboards.
- The distance from the nearest viable circuit. A socket on the opposite side of the room from the ring main requires more cable, more labour, and more making-good afterwards.
- Property type and wall construction. Solid brick and concrete walls take longer to chase than stud partition walls, adding to labour time.
- Location within the property. Kitchens and bathrooms have stricter regulations under BS 7671 (18th Edition Wiring Regulations) regarding socket placement zones, which can increase complexity.
- Your region in the UK. London and the South East typically cost 20-30% more than the national average, while rates in the North and Midlands tend to be lower.
- Whether the work requires Part P Building Regulations notification. Adding a new circuit or working in a special location (bathroom, outdoors) must be signed off by a registered competent person or building control.
- The socket specification. Standard white plastic sockets are cheapest; brushed chrome, brass, or smart sockets with USB-C and Wi-Fi cost more for both the unit and fitting time.
How Long Does It Take?
A straightforward like-for-like socket replacement typically takes 30 to 45 minutes. Installing a completely new socket with wiring from the ring main usually takes 2 to 3 hours, depending on cable routing distance and wall construction. If multiple sockets are being added in one visit, expect roughly 1.5 to 2 hours per additional socket after the first, as the electrician can work more efficiently once set up. If extensive making good is needed — for example, replastering a long cable chase — allow an extra hour.
Do I Need This?
You may need a new socket if you are regularly relying on extension leads or adaptors, which can be a fire hazard when overloaded. Additional sockets are also common during kitchen or bathroom refurbishments, home office setups, or when mounting a wall TV and wanting a socket behind it. If an existing socket is cracked, discoloured from heat, or sparking when you plug something in, it should be replaced promptly. Outdoor sockets are increasingly popular for EV charging preparation, garden power tools, and outdoor entertaining. In all cases, using a qualified electrician ensures the work complies with BS 7671 and Part P of the Building Regulations.
How to Save Money
Bundle multiple sockets into one visit. Most electricians charge a call-out or minimum fee, so having two or three sockets installed at once significantly reduces the per-socket cost.
Supply your own sockets if you want a premium finish. Buying designer faceplates online can be cheaper than the electrician's mark-up, though check with them first that the units are compatible.
Opt for surface-mounted trunking instead of chasing into walls. It is less visually discreet but much faster and cheaper, as it avoids plastering and redecorating costs.
Get at least three quotes from local electricians. Prices vary significantly, especially in cities, and comparing quotes ensures you pay a fair rate.
Time the work alongside other electrical jobs. If you are already having a consumer unit upgrade or rewire, adding sockets at the same time is far cheaper than booking a separate visit.
