Final price depends on access, cable routes, existing wiring and scope. Survey is free; written quote is fixed. Read the disclaimer below the cards before assuming.
Yes. We do farm wiring, workshop sub-boards, SWA submains across yards, agricultural-rated sockets and showground temporary supplies. Everything compliant with BS 7671 Section 705 (agricultural) and properly IP-rated for the environment.
An extension lead from the house is not a permanent installation — it's not BS 7671 compliant for a fixed garage circuit, and it's a real fire risk under load (a single 13A flex feeding a fridge, freezer, lights and tools will overheat). The compliant solution is an SWA armoured submain from the main consumer unit to a sub-board in the garage, with its own RCBO protection. It's the cost difference between £50 of flex and £850 of compliant install — but it's the right answer for safety, insurance and resale.
If the garage has more than 2-3 circuits (lights, sockets, EV charger, motor) then yes — a 4 or 6-way sub-consumer-unit gives proper local isolation, RCBO discrimination and clear labelling. For a small detached garage with just lights and 2 sockets, a single circuit on its own RCBO at the main board is fine.
