If you don’t have an outdoor plug socket, it's hard to appreciate the benefits they offer. But I can tell you, once I had one installed, I didn’t know how I managed without one. No more dragging cable through the window, and no more stretching out an extension cable. They are convenient and relatively inexpensive to install.
However, it's not a task for a DIYer who hasn’t done any electrics before. And, even if you do the job yourself, you will still need to get the work certified by a professional to make it legal. Here, we look at where to install an outdoor socket, which sockets to use, and whether it's wise to install it yourself.
Reasons for an outdoor plug socket
Outdoor plug sockets are typically installed in outdoor spaces such as sheds or garages, or on exterior walls, depending on the installation location. The common reason for an external installation is to conveniently run powered garden tools, such as lawnmowers and strimmers. They can also be used for outdoor lighting and heating, like this Sealey Infrared Quartz Heater from B&Q.
And, of course, they have seasonal uses, as Andy Simms of MyBuilder points out: “For many Brits who set up their outdoor Christmas lights, an outdoor plug socket will be very useful.”

An IP66-rated moulded enclosure made from high-impact and self-extinguishing ABS. Ideal for any outdoor connections that need need protect from the weather.
Where to install an outdoor plug socket
The simple solution is to place it where it is most convenient. But make sure the surface is solid so the socket (like this BG Decorative IP66 13A DP Switched Socket 2 Gang from Toolstation) won’t detach and become dangerous. If installing yourself, use an SDS drill like this Berserker SDS-Plus Rotary Hammer Drill with suitable masonry drill bits like this Toolant Concrete Drill Bit Set, both from Amazon, if drilling into masonry. Don't forget to use Rawl plugs like these Plasplugs Super Grips Red Plastic Wall plug from B&Q to secure.
However, there are rules to follow, explains Simms, “Your socket must be placed at least 30cm above the ground, to prevent damage from rainfall.” He adds, “It’s also recommended that it’s mounted to a solid surface away from potential rain, such as on a wall under an eave.”
To finish, he says, “Install near the consumer unit, which minimises the length of external cabling that’s needed. “ And as an added precaution, he adds, “A separate circuit, although not mandatory, is recommended, as it can help prevent an electrical overload.”
Socket type to use outside
An outdoor socket needs protection from the elements, so you will need a specific type. Simms explains what’s needed and why, “When selecting your socket, make sure to choose one with a high ingress protection (IP) rating - a rating of IP 66 is recommended.”
He adds, “This will ensure that your socket is protected against damage if in contact with dust, objects or water.”
You can use an IP55-rated socket outdoors, such as this BG IP55 Socket from Toolstation, but these don’t provide as much protection. But they are still ideal for use inside a shed or garage.
In addition to a socket, Simms says you’ll need protection: “Your socket will also need a 30mA Residual Current Device (RCD).” He adds, “Which you should already have if you’re connecting your socket to your main consumer unit. This will shut off power in the event of a fault.”
How an outdoor socket is typically installed
A popular method is to feed a weatherproof cable (such as this Pitacs SWA single-phase armoured cable from Toolstation) from an existing indoor socket. Choose one that is protected by an RCD at the consumer unit. If not, you will need one installed (you’ll need an electrician).
With the electrics and cable sorted, the final step is to mount the plug socket and cover, and connect it to the cable. Use an external silicone sealant, such as this Everbuild External Frame Sealant from Amazon, at any points where water and dust can enter.
Cost to install an outdoor socket
The costs are broken down into two parts: materials and labour. Simms shares how much you can expect to pay for labour, “The price, excluding materials, typically ranges from £75 to £100, although this can cost more, even up to £200, due to additional safety features that may be required.”
More complex jobs and additional sockets will cost more; as a rough guideline, electricians charge around £50 an hour. The cost of the selected electrical socket will affect the overall project cost. A basic double socket like the BG Electrical Outdoor Double Switched Power Wall Plug Socket from Amazon costs less than £13. A single socket is slightly cheaper.
Obviously, the more sockets you have, the more it will cost to buy and install. Simms suggests one way to save on costs: “You can reduce costs slightly by installing your socket closer to your consumer unit, as cables will run at a reduced distance.”
Can I install an outdoor plug socket myself?
If you have experience with household electrics, you can handle simple jobs yourself, but it is not recommended to undertake electrical work if you are not qualified. Paul Kerr, building specialist at Beatsons, says, “Many homeowners are confident in DIY; however, installing a fixed socket is one of those situations where I would advise taking a step back and calling a professional electrician.”
But it's not just the lack of experience or knowledge that can be an issue, continues Kerr, “The DIY alternative is complicated. And not only that, Building Regulations cover new fixed electrical work in a domestic setting, which means there are many key regulations to consider.”
He adds some sensible advice, “The simplest and safest option is to hire a registered electrician who can self-certify the electrical work, ensure it complies with the correct regulations, such as the IET Wiring Regulations (BS 7671), and notify Building Control.”

FAQs
Does an outside socket need to be certified?
The quick answer is Yes, as Kerr shares, “Yes, definitely. Any fixed electrical installation needs to be certified, including an outdoor socket.”
He reveals the issues that can arise if you don’t get an electrical installation approved: “Without the correct certification, you will risk invalidating your home insurance in the case of an electrical fault causing fire or damage, and it could also cause issues when it comes to selling your property.”
Is there a quick option for an outdoor socket?
Installing a permanent outdoor plug socket is the preferred option, shares Kerr, “The best course of action if you regularly need power in the garden is a hard-wired permanent outdoor socket certified by an electrician.”
However, if you need a quick solution, you can use an extension like this Haraqi IP66 Waterproof Outdoor Extension Lead Socket from Amazon. But Kerr doesn’t recommend them for long-term use, “Although a quick fix like a weatherproof extension box can be appealing, I would advise going for a permanent switched socket. A weatherproof extension box is a temporary solution, e.g. for using a pressure washer, rather than a long-term solution.”
He adds, “Using them continuously can cause cable damage, they can be likely to overheat, and can be easily overloaded.”
