How To Get Electricity Outside In Your Garden

How To Get Electricity Outside

As soon as the weather perks up with a bit of sun, our phones and inboxes become busy with customers requiring garden electrics. From running electricity to a shed to installing armoured cable for a garden office, we’ve carried out a range of outdoor electricity projects.

To provide you with some detail on the process of installing electricity outside, whether that’s for outdoor lighting or a much larger project, below is everything you need to know.

How To Get Electricity Outside

To provide electricity to an outdoor building, such as a shed, garden office or summer house, you must run an armoured cable from your main house supply to the external building.

Ideally, this cable should be buried underground (usually 600mm deep) and connected to a new consumer unit installed in the garden building.

Alternatively, you can secure it above ground, shielding it from potential physical damage. When running the cable above ground, it should be fixed to a stable structure, such as a wall or a fence, and kept out of reach to avoid accidental damage.

It’s crucial to avoid attempting this project yourself unless you are a qualified electrician. Properly supplying electricity involves technical expertise to accurately calculate resistance and ensure compliance with Part P Electrical Safety regulations. While the process can be complex, it is not time-consuming and should not be overly expensive to complete.

What Electric Cable Should You Use Outside?

The correct type of armoured cable you use is crucial to ensuring safety and that it complies with the Part P Electrical Safety regulations.

For most installations, armoured cable (SWA) is used as it’s extremely durable and perfect for use under and above ground. Other cables that could be used are a UF-B, THWN-2, and SOOW type, but we recommend running through the details with our team before purchasing any cable in bulk.

If you are unsure about the armoured cable you require, please get in touch with us, and we will provide you with the details you need.

Reducing The Cost

Doing it yourself can reduce the cost of installing electricity outside. However, we only recommend doing things that don’t require the expertise of an electrician.

For example, digging a 600mm underground trench from your house to the area where you want power will certainly reduce the cost. Alternatively, you may want to secure the cable above ground to reduce the labour costs of digging a trench.

Regarding materials, armoured cable can be expensive, and you’ll want to avoid over-specifying and purchasing a longer length than what’s required.

Hopefully, our guide to installing electrics in your garden or outdoor space has answered all your questions. During the summer months, our team of electricians really enjoys this type of work, and over the years, we’ve solved a wide range of exciting problems.
