How To Supply Electricity To A Garden Shed

Depending on your needs, you may never need to run electricity to your garden shed. For example, if you use your shed for storage purposes only, it isn’t necessary to go through an electrical installation. However, if you use your shed as a workstation, it may be beneficial to run electricity to it from your house in order to make your work more streamlined.

The same can be said for if you use your garden shed as a man cave or a garden bedroom. There are a lot of different ways in which you can add electricity to your shed, and some are easier and more practical than others. Below is our guide on how to get electricity to your garden shed.

Work With A Professional

For more complex electrical needs, it may be necessary to work with a licensed electrician, who can make the process of installing your supply a lot safer and easier. Electricity can kill, and if you don’t know what you’re doing, it can put both you and your loved ones at risk.

Install An SWA

An SWA is a steel wire cable that will run from your property to your shed. There are different types of this cable depending on your needs, which is another reason for choosing to work with a licensed professional. They can help you decipher which SWA is right for you, and can bury it underground correctly in order to protect it from adverse weather conditions such as ice and rain.

Identify Socket Placements

Usually an afterthought, socket placement should be high on your priority of things to do. It can affect the layout of your garden shed, and will determine the right direction for your SWA cable. The more sockets you have, the more complex the installation may be, so you should take this into account when making your placement choices.

Lay The Groundwork

Once the spaces for sockets have been identified, you can plan where your cable will run. For most cases, you’ll connect your SWA to an existing fuse box. However, you may need to upgrade your fuse box in order to run electricity outdoors. If this is the case, your electrician will let you know accordingly. Before your cable is laid, you will need to check that there are no obstructions, such as water or gas pipes.

Prepare A Trench

Once all your preparation and planning are complete, you’ll need to start outlining and digging your trench for the SWA cable. Ideally, you’ll need to prepare your trench quickly before laying the cable itself, ensuring no heavy rain can flood the area. To keep costs down, you can dig the trench yourself, just ask your electrician for details on depth and width.


Once everything is ready, carry out the work. This is the easy part, especially if the electrician you’re working with is laying the wires for you. Once this is done, test that everything works. If so, you’re good to go!
