How Much Does It Cost to Install Garden Power?
£300 – £1,200
per job
Installing power in a garden costs between £300 and £1,200 depending on the number of outlets required, the length of the cable run from the house, and whether armoured cable needs to be buried. A simple outdoor socket on the house wall is at the lower end; running power to a garden office or outbuilding at the far end of the garden is a larger job.

Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Cable run length - armoured SWA cable must be buried at least 500mm deep; longer runs from the consumer unit cost more in materials and groundwork
Number of outlets - a single outdoor socket is cheapest; a garden office requiring multiple sockets, lighting, and an RCD unit costs significantly more
Trenching and groundwork - digging a trench across a garden adds labour time; reinstatement of lawn or paving adds further cost
Consumer unit capacity - a new circuit is required; if there are no spare ways in the board, a consumer unit upgrade may be needed
Labour vs materials
Labour accounts for 50-60% of the total cost for garden power installation. Armoured cable costs £3-£8 per metre; groundwork and reinstatement add to the overall project cost.
