There is no legal minimum number of sockets per room in the UK. Building Regulations set standards for the safety of electrical installations, but they do not specify how many sockets you must have. However, there are industry recommendations, and getting the number right avoids reliance on extension leads and multi-socket adaptors, which are a common cause of electrical fires.
Recommended socket numbers by room
The following recommendations are based on guidance from the Electrical Safety Council and practical experience of what modern households actually need.
Kitchen
Recommended: 6 to 8 double sockets
The kitchen is the most electrically demanding room. You need dedicated worktop sockets for countertop appliances (kettle, toaster, food processor, stand mixer) plus connections for fixed appliances (fridge, freezer, dishwasher, washing machine). Under-cabinet areas and island units need their own provision too.
Kitchens also benefit from:
- At least one double socket with integrated USB for device charging
- A dedicated circuit and connection for the cooker or hob
- Fused spurs for hardwired appliances (dishwasher, waste disposal)
Living room
Recommended: 4 to 6 double sockets
A typical living room needs sockets for a TV, set-top box, games console, lamp, phone charger, and possibly a laptop. If you have a home cinema setup, you may need more. Sockets should be distributed around the room so you are not running cables across walkways.
Consider placing sockets:
- Behind the TV position (at least 2 double sockets)
- Either side of the sofa for lamps and charging
- Near the fireplace or feature wall
Bedroom
Recommended: 2 to 4 double sockets
Each side of the bed needs a double socket for a lamp and phone charger. If the bedroom has a desk or dressing table, add sockets at that location too. Children’s bedrooms may need more as they get older and accumulate devices.
Home office
Recommended: 3 to 4 double sockets
A home office has specific needs: computer, monitor (or two), desk lamp, phone charger, printer, router, and possibly a second screen. A dedicated circuit is ideal if you are running equipment that should not be affected by other household loads.
Consider adding:
- A hardwired Ethernet point for reliable internet
- USB-integrated sockets for device charging
- Sockets at desk height rather than floor level
Bathroom
Recommended: 0 to 1 shaver socket
UK regulations restrict socket types in bathrooms. Standard 13A sockets are not permitted. A shaver socket (complying with BS EN 61558-2-5) can be installed outside zones 0, 1, and 2. Electric toothbrush chargers and shavers can use this.
Larger bathrooms or en-suites may benefit from a fused connection unit outside the room for a heated towel rail or underfloor heating.
Hallway and landing
Recommended: 1 to 2 double sockets
Often overlooked, but useful for a vacuum cleaner, a lamp on a console table, or charging devices near the front door. A socket on the landing is useful for vacuuming upstairs.
Garage
Recommended: 2 to 4 double sockets
For power tools, a chest freezer, and general workshop use. If you are installing an EV charger, this needs its own dedicated circuit from the consumer unit, not a standard socket.
Garden room or home office
Recommended: 3 to 4 double sockets + dedicated heating circuit
A garden room used as an office needs the same socket provision as an indoor home office, plus a dedicated circuit for an electric heater or air conditioning unit. The supply is run from the main house via armoured cable.
Common mistakes
Not enough sockets in the kitchen
This is the most frequent complaint. Kitchens are designed around units and worktops, and the number and position of sockets needs to match the layout exactly. Adding sockets after the kitchen is fitted is possible but more disruptive.
Relying on extension leads
If every room has extension leads and multi-socket adaptors, you do not have enough sockets. Each adaptor is a potential point of failure and overheating. The solution is to add more permanently installed sockets.
Forgetting about future needs
If you are renovating, think about what you might need in two to five years. An EV charger, a home office, smart home devices, or a garden room may all require additional circuits. It is far cheaper to run cables during a renovation than to add them later.
Sockets in the wrong position
Position matters as much as quantity. Sockets behind large furniture are useless. Sockets at floor level behind a desk mean cables trailing across the floor. Plan socket positions around how the room will actually be used.
Adding sockets to your home
Adding sockets to an existing room is straightforward. A single additional double socket typically costs between £80 and £150 depending on the cable route. Adding a new circuit from the consumer unit costs more but is sometimes necessary if the existing circuit is already at capacity.
