How to get electricity into your garden building.
Installing electricity into your building adds an extra level practicality and comfort and one that should be seriously considered during the design of your building (as it is more complicated after construction)..Electricity is a major factor in the success when you are working from home for computers or other appliances.
There are two aspects that you need to consider:
- The wiring and installation of sockets and switches within the building
- Getting the supply of electricity from the house/property to the garden building itself
We install a fuse board similar to the one shown in the image on the left, this has to be wired by your own electrician.
An armoured cable has to be connected directly from your main house supply to the garden building. This should (ideally) be buried under the ground and is then 'hooked' up through a consumer unit installed in the garden building by your electrician.
Supplying electricity from your house to your shed is something that you should never attempt yourself (unless you are a qualified electrician). It requires professional, technical expertise to correctly calculate resistance and to ensure that it falls within the specification of Part P Electrical Safety work regulations. Although a little complex, it is not particularly time intensive, so should not be very expensive to complete.
Keeping the cost down.
There are ways you can keep the price down, if you’re willing to put in some of the work yourself .
Running the armoured cable underground from your house to your shed requires a trench to be dug and this will be one of the more costly aspects to the job. If you are prepared to undertake the manual labour and dig the 600mm trench yourself, you can reduce the costs. Mention this when the electrician provides a quote to get a revised price.
If you have completed the trench yourself, then the electrician can begin the main work immediately. Changes may need to be made to your fuse box to be manage the additional power draw and a residual circuit breaker (RCB) may be added for extra safety. The cable will be wired into the main fuse box in your house and laid in the trench. All that remains is to hook the wire up to the sub panel in our pre-installed electrical pack and the job is complete.
Costs will vary depending on the distance the cable needs to cover between the house and garden building and after the job is completed you will need to obtain a Certificate of Work. This is especially important if you come to sell your house and acts as your P certification for legal purposes.
We can help and advise you during your free design consultation if you have any further questions regarding this.
