A garden office only works year-round if it has a proper electrical supply behind it. A few sockets run off an extension lead will not power heating or air conditioning safely. Here is what a proper installation involves.
A dedicated supply
We run a correctly sized steel-wired armoured (SWA) sub-main from the house, buried at the right depth, to a small consumer unit in the garden office. That gives you a safe, independent supply rather than overloading a house circuit.
Sizing for how you’ll use it
If you plan to run a heater, air conditioning and a few monitors, the supply needs to be sized for that load from the start. It is much cheaper to size it correctly now than to upgrade later.
Sockets, lighting and sign-off
We fit the sockets, lighting and any heating or air conditioning, then test, certify and notify the work so your garden office is safe and compliant.
