Adding Sockets to Your Home: A Complete Guide

If you find yourself constantly shuffling plugs, using extension leads, or fighting over the one socket in a convenient location, you're not alone. Many UK homes, particularly older ones, simply don't have enough sockets for modern life. The good news is that adding sockets is one of the most straightforward electrical upgrades you can make, and it can dramatically improve the functionality and safety of your home.

Why Add More Sockets?

The average UK home built in the 1970s or earlier was designed with far fewer electrical devices in mind than we use today. A typical living room might have had just two or three double sockets – enough for a TV, a lamp, and perhaps a record player. Today, that same room might need to power a TV, set-top box, games console, soundbar, multiple phone chargers, a laptop, smart speakers, and more.

Relying on extension leads and adapters to bridge this gap isn't just inconvenient – it can be dangerous. Overloaded extension leads are a common cause of electrical fires. Adding properly installed sockets eliminates this risk while making your home more functional.

Types of Sockets Available

Standard Double Sockets

The most common choice, providing two 13A outlets. These are suitable for most general-purpose applications and are the most cost-effective option for adding capacity.

USB Sockets

These combine standard 13A outlets with built-in USB ports (Type A, Type C, or both). They're perfect for bedrooms, living rooms, and home offices where you regularly charge phones and tablets. No more hunting for chargers or using up socket space with adapters.

Switched vs Unswitched

Most UK sockets are switched, allowing you to turn off individual outlets without unplugging. This is safer and more convenient, though unswitched sockets are sometimes used for appliances that need constant power, like fridges or freezers.

Single Sockets

Useful where space is limited or where you only need one outlet – for example, behind a fridge or washing machine.

Outdoor Sockets

Weatherproof sockets rated IP66 for outdoor use. Essential for gardens, patios, and garages. These must be RCD protected for safety.

Floor Sockets

Installed in the floor, these are useful for large rooms where wall sockets would require trailing cables across walkways. Common in home offices and living rooms with central furniture arrangements.

How Sockets Are Added

There are several ways to add sockets to your home, depending on your existing installation and requirements:

Spur from Existing Socket

The simplest method is to "spur" a new socket from an existing one. A cable runs from the back of an existing socket to the new location. This is quick and minimally disruptive, but there are rules about how many spurs can be taken from a ring circuit.

Adding to the Ring Circuit

For multiple new sockets, it may be better to add them directly to the ring circuit. This involves running cable back to the consumer unit or connecting into the ring at a convenient point.

New Radial Circuit

For high-power applications or areas with many sockets (like a home office or kitchen), a new radial circuit from the consumer unit may be the best option. This provides dedicated capacity and is often required for specific applications.

Surface-Mounted vs Flush

Sockets can be surface-mounted (the back box sits on the wall) or flush-mounted (the back box is recessed into the wall). Flush mounting looks neater but requires chasing into the wall, which is more disruptive and time-consuming.

Regulations and Requirements

Adding sockets is generally considered "minor electrical work" and doesn't require notification to building control, provided:

• The work is not in a bathroom or other special location
• A new circuit is not being added
• The consumer unit is not being altered

However, the work must still comply with the Wiring Regulations (BS 7671) and be carried out competently. Using a registered electrician ensures the work is done safely and to the required standard.

Where to Add Sockets

When planning additional sockets, think about both current needs and future requirements. Common locations include:

Living Room

• Behind the TV position (consider a media plate with multiple outlets)
• Either side of the sofa for phone charging
• Near the Christmas tree position
• For floor lamps and other lighting

Kitchen

• Above worktops for small appliances
• In the utility area for washing machine and dryer
• For the fridge/freezer (ideally on its own circuit)
• Island units (floor sockets or pop-up sockets)

Bedroom

• Either side of the bed for lamps and charging
• Near the dressing table
• For TV and entertainment equipment

Home Office

• Behind the desk (multiple sockets for computer equipment)
• For printers and other peripherals
• USB sockets for charging devices

Garage/Workshop

• For power tools
• Workbench area
• EV charger (requires dedicated circuit)

Socket Heights and Positioning

While there's no legal requirement for socket heights in most rooms, there are practical considerations:

• Standard height: 450mm from floor to centre of socket
• Accessible height: 400-1000mm for wheelchair users and those with mobility issues
• Kitchen worktop: 150mm above worktop surface
• Behind furniture: Consider the height of the furniture

In bathrooms, there are strict rules about socket locations – generally, sockets are not permitted except for shaver sockets in specific zones.

Costs of Adding Sockets

The cost of adding sockets varies depending on several factors:

• Number of sockets: More sockets mean more materials and labour
• Type of socket: USB sockets cost more than standard ones
• Installation method: Flush mounting costs more than surface mounting
• Cable runs: Longer runs or difficult routes increase costs
• Making good: Plastering and decorating after flush installation

As a rough guide:

• Single socket (spur from existing): £80-£120
• Double socket (spur from existing): £100-£150
• Multiple sockets in one room: £150-£300
• Outdoor socket: £150-£250

These prices typically include the socket, installation, and basic testing, but not decorating.

DIY vs Professional Installation

While some minor electrical work can legally be done by homeowners, adding sockets involves working with mains electricity and should be approached with caution. The risks of incorrect installation include:

• Electric shock
• Fire from overloaded circuits or poor connections
• Damage to existing wiring
• Non-compliant installation affecting insurance
• Problems when selling your property

Using a qualified electrician ensures the work is safe, compliant, and properly tested. You'll also receive documentation confirming the work meets required standards.

Planning Your Socket Upgrade

Before calling an electrician, it's helpful to:

1. Walk through each room and note where you currently use extension leads
2. Think about furniture arrangements and where sockets would be most useful
3. Consider future needs – home office, EV charger, garden room
4. Decide on socket types – do you want USB ports?
5. Think about aesthetics – do you want flush or surface mounting?

An electrical installation consultation can help you plan the most effective socket layout for your needs.

Conclusion

Adding sockets is one of the most practical improvements you can make to your home. It eliminates the need for dangerous extension leads, makes your home more functional, and can even add value to your property. Whether you need a single socket in an awkward spot or a complete upgrade throughout your home, professional installation ensures the work is safe, compliant, and built to last.

Don't put up with inadequate sockets any longer – a simple upgrade can make daily life significantly more convenient.
