Our Guide to electrical specification
When buying a garden office, check that your supplier’s price includes the installation of internal wiring, double sockets and switches, low energy light fittings and a consumer unit. Does the price also include data cabling or a telephone line for your computer? Are electric convector heaters included? NB. Most suppliers make an additional charge for bringing electricity from the house to your garden office.
Sockets and lights
Do you want to vary the number of sockets and lights in the office of your choice? Even the smallest garden office should have eight or ten double sockets, two or three low energy wall lights and an external security light. In a larger office you will may need twelve to sixteen double sockets and four or five low energy wall lights. If this seems a lot, count up the number of electrical items you use in your office. Then add all the phones, cameras etc that you regularly charge. you will also need spare sockets for task lighting.
Adding photo voltaic panels
If you office is large enough you could generate a percentage of your own electricity with photo voltaic panels. This is not a cheap option, but it may be a viable long term investment if your office faces the right way and you intend to live in your current house for a long time.
Some garden office companies offer underfloor heating in their buildings. This may be OK for you if you are going to use your building regularly and for long periods of time. However, it does take a relatively long time to warm up, and is hard to maintain at a steady heat in a timber building. You may find that a simple convector heater is more efficient and much cheaper to run.
