Adding a plug socket to a room cost guide

Why add a plug socket to a room?

Chances are you’ve run multiple plugs from a single socket with various multi adapters in the past. Or, maybe you’ve run long extension cables across rooms to reach specific appliances. The problem is these options aren’t always safe, can overload the circuits, can cause tripping hazards and increase the risk of a fire. You may also have old and dangerous sockets that need replacing (such as those identified during an electrical safety check).

To solve these problems, and ensure you have access to power where you need it, installing new plug sockets is the ideal solution. It’s also the next step you’ll need if building an extension, creating a home office, or changing a room’s layout. Adding a plug socket to a room costs less than the risk of fire damage, and is easily worth it for the added convenience and safety benefits.

Common types of plug socket

To calculate the cost of installing additional plug sockets, you’ll need to decide which type is right for you. Some of the most common types include:

  • Single: A standard socket with a single plug. These are useful for single appliances, or tight spaces. They cost between £50 – £200.
  • Double: Double sockets are better value than fitting two single sockets and help future proof your home in case you need to use more devices in the future. They are also more desirable to potential buyers when selling a home. Double sockets cost between £100 – £300.
  • USB socket: These cost a little more than single sockets but give you the added convenience of being able to charge by USB whilst keeping the plug free for other appliances. They are very useful for heavy tablet and phone users. USB sockets cost between £65 – £90
  • Outdoor socket: If you need to use your plug outside – such as for a lawnmower, hot tub or other external appliance – then you’ll need an outdoor plug. These cost between £85 – £135.

Cost of installing a new plug socketImportant considerations

When deciding where to place your new plug, and what sockets are needed, you should consider the following:

  • Pick a location for convenience and safety. For example, in the kitchen it needs to be well away from any sources of water or heat.
  • If someone elderly lives in the home, positioning plug sockets 40-50cm above the floor, instead of the standard 15-20cm, can help make it much easier to change plugs.
  • Try to plan ahead so multiple sockets can be installed at the same time, which can be more cost-effective.
  • Decide which type of socket is best for you based on what you will use it for. Double sockets are a great way to future proof your home.
  • Check if your fuse box or consumer unit is able to cope with additional sockets. An electrician can help advise you if this is the case.
  • Plug sockets come in different colours and styles so choose the one that best matches your needs and decor.
  • Metal sockets must be earthed, so ensure that your electrician will do this.
  • Consider replacing existing single sockets with double sockets as a lower-cost solution.
  • Check if your electrician will use a plasterer to repair the walls after the work has been completed, or if you will need to do this.

Factors affecting the cost of installing additional plug sockets

  • Type of plug socket chosen: As we have shown above, the cost of installing a new plug socket is heavily driven by the type of socket you choose.
  • Number of sockets: To save on future work you can opt to have more sockets done as part of a single job. A little bit of planning beforehand can save you wasted labour costs later.
  • Style, colour and quality of socket: A standard white socket costs less than brushed steel, black nickel, polished chrome and other styles.
  • Ease of access: To save on the labour time you should make it as easy as possible for the electrician to access the space. This can be done by moving furniture and appliances.
  • Moving current socket or adding new socket: Moving a socket a short distance can be cheaper than adding a new one if your electrician is able to use the existing wiring.
  • Location: Electricians will charge more the further away from their core location you are, so finding an electrician near you will ensure cheaper rates. You can also expect to pay more in London and the South East.
  • Whether extra wiring is needed: Adding a plug socket to a room costs more the further away from other connections it is. The price will also rise if any rewiring is needed for faulty connections.

cost of installing additional plug socketsCost to move a plug socket

The way we use our rooms can change a lot over time. From new furniture to new arrangements and even by knocking through walls. So sometimes the location of sockets needs to be changed to suit the new usage.

On average, the cost to move a plug socket is £150. This will vary depending on how far it is moved and the condition of the socket.

Can I install a plug socket myself?

We highly recommend a professional electrician be hired for this work. It is always dangerous to work with electrics and if not done properly can be a fire and electrical hazard. Hiring a professional electrician gives a guarantee the work is done properly and safely, in line with building regulations. They can also inspect the electrical circuits and fuse boxes to make sure they’re up to scratch.

How long does it take to install a new plug socket?

It can take around 1-2 hours to install a new plug socket. This time will increase if considerable new wiring is needed, or in the case of an extension will take a lot longer if the room hasn’t yet been wired.

How much are labour costs?

We recommend reading our electrician hourly rate guide for a detailed run down of hourly and daily rates. Typically, the labour costs for this job would be £40, although this varies based on experience level and location.

Useful plug socket installation checklist

  • Using multi-plug adapters and long extension cables can be unsafe. Installing new sockets removes this risk.
  • Consider which type of socket you’d like: single, double, USB or outdoor, as well as the style.
  • The cost of installing a new plug socket is more than replacing an existing socket.
  • By planning ahead you can save money on future electrical work.
