Cost to install outdoor socket

Why install an outdoor socket?

If you want to use electrical equipment safely outside your home then the best way is via an outdoor socket, or exterior power point. In this guide we look at the cost to install outdoor socket and answer the question “how much to have an outdoor socket fitted?”.

By adding an outdoor socket you’ll have the convenience of not running long power cables from your home. That means no more annoying trip hazards just to mow the back garden, or to do a bit of outdoor DIY with an electric drill.

Alongside this convenience, you’ll have a dedicated power source for any long-standing outdoor fixtures, such as hot tubs, outdoor pools, or outdoor lighting. Or, even for using multiple items at a garden party in the Spring or Summer. Plus, you can be sure you have a waterproof and durable power source to reduce the risk of any faults.

You can even add an outdoor power socket to the front of your property. They’re ideal for any car washing or pressure washing equipment. However, if you have an electric vehicle it’s recommended you look into electric car charger installation costs.

Outdoor plug socket costsCost + VAT
(Range low - high)
Average cost
Cost to install outdoor socket (materials)£15 - £60£37.50
Cost to install outdoor socket (labour)£80 - £130£105
Cost to install a double outdoor socket (labour)£85 - £135£110

If you’re wondering “how much does an outdoor socket cost?” then you’ll need to work out two costs; the materials and the labour. On that basis, average costs will be £37.50 for the materials and £105 for the labour.

This means the total cost to install outdoor sockets is £142.50 on average.

Interestingly, this puts the cost of installing an outdoor socket at only slightly more than a standard indoor socket. As we found in our cost guide on adding a plug socket to a room, the average cost for a single indoor socket is £125. At only £17.50 more, outdoor sockets are a very attractive option.

Cost of outdoor plug socket with waterproof coverWhat is an RCD?

You may hear the acronym ‘RCD’ mentioned in relation to outdoor plug sockets. RCD means “residual current device” and is a mandatory feature in many power sockets now. Sockets with this feature will cut off electricity if there is a fault, such as if you cut through your lawnmower cable. This is essential to protect you from fatal shocks.

The cost of an outdoor plug socket with RCD is more expensive but can be cheaper overall when you factor in installation. Without an RCD in the unit, your electrician will need to connect to an RCD somewhere else in your home. Connecting this can require more labour time and cabling, pushing up the cost to fit outdoor sockets.

RCD sockets also include covers that trap the cable in place. As a result, there’s no risk of pulling the cable out if you yank it accidentally or it gets stuck during use. Not only is this feature convenient, but it also makes the use of your outdoor equipment safer.

Important considerations when installing an outdoor socket

When choosing an outdoor socket and considering what devices you will use with it, you must consider the following:

  • The plug socket and any cables must be waterproof and rated for use outdoors.
  • Any electrical devices left plugged in outside must also be waterproof and rated for outdoor use.
  • Cables must be frost proof and waterproof. Ideally, they should be exposed to the elements as little as possible.
  • Periodically check cables and devices left outside to ensure they have not been damaged by pests.
  • Cover any cables to ensure they are not tripping hazards.
  • You need to comply with building regulations and electrical regulations.
  • As discussed above, it is wise to choose a socket with an RCD and that prevents accidental tugging.

Cost to fit and wire outdoor socketFactors affecting the cost of outdoor plug sockets

  • Type of socket: Depending on whether you want an RCD socket, single plug or double plug, the cost to install an outdoor socket will vary. For example, the average installation cost for a single plug is £105, whilst a double plug is £110, so you can save a lot of money in the long run by using double plugs.
  • Electrical inspection: For older homes your electrician may recommend you have an electrical safety check. This will ensure your consumer unit can cope with the extra plug and power drawn.
  • Position of socket: The further your external power point is placed from other sockets then the more cabling will be needed to connect it. This will increase the labour time.
  • Usage: If you want your electrical devices to turn off and on at certain pre-set times, then choosing an outdoor plug socket with a timer will let you do so. This is ideal for lighting, heating and Christmas lights.
  • Experience level of your electrician: The price you pay your electrician will vary based on their experience level and where you live in the UK. We’d always recommend you get the best quality electrician you can afford to reduce any issues down the line.
  • Number of sockets: If you need two plugs it’s far cheaper to install a double socket than it is to install two singles. Likewise, it’s cheaper to install two sockets today than a second socket later on. So, be sure to think about your long-term plans if you want to save money.
  • Accessibility: In addition to the distance from other plugs, the price you pay will also rise if the socket is in a hard to reach area. If you require the socket as a fixed feature away from the wall, such as a box at the end of the garden, this will further increase costs as well.

Can I install an outdoor socket myself?

As with all electrical work, there is a significant risk of damage to yourself or your home if the installation is not done correctly. A professional electrician will draw on their knowledge and experience to help you choose the best socket and amperage levels. They will ensure the work complies with regulations and you’ll have the peace of mind that you can use the socket safely.
