What moves the price
- Distance from the main supply — a longer run to the outbuilding needs more armoured cable and a longer trench to bury it.
- Armoured cable size — a workshop or heavy load needs thicker armoured cable, which costs more per metre than a light supply.
- Any additional features like lighting or outlets — each extra socket, light or outside light in the outbuilding adds parts and wiring time.
- Sub-board and protection — a separate sub-board with its own protection in the outbuilding adds parts and connection time.
- Condition of existing electrical infrastructure — if the house board has no spare way for the outbuilding supply, a board upgrade may come first.
- Accessibility of the site — a long or awkward route for the cabling to the outbuilding adds time.

How to pay less
- Digging the trench for the armoured cable yourself, to the depth the electrician specifies, can cut the labour cost.
- Running the cable along an existing wall or fence line, where the electrician agrees, can avoid digging a long trench.
- Planning every socket and light the outbuilding needs now costs less than adding a second supply or circuits later.
- Sizing the supply for what you will actually run, rather than heavy workshop loads you may never use, keeps the cable cost down.
Before you book
- Access to the main electrical supply and the outbuilding.
- Information about intended use of the outbuilding to determine power needs.
