Garden Office Power & Lighting in a Conduit System — Sale
Power and lighting installed for a new garden office in Sale, Trafford: conduit system from the main consumer unit out to a sub-board in the office, dedicated work-from-home circuits, internal lighting, all to current 18th edition standards.
What we did on this Sale job
The detail behind the project — what the client needed, how we approached it, and what was specified for the future.
A homeowner in Sale, Trafford, needed power and lighting installed for a newly-built garden office. The right answer for outbuildings is a proper conduit system — cables run inside protective plastic or galvanised conduit, either underground in armoured ducting or surface-mounted on the structure itself — feeding a small sub-board in the office that splits dedicated circuits for sockets, lighting, and any heating or networking equipment.
Conduit is the right call for outbuilding electrics for three reasons. First, it protects the cable from ground movement, garden tools, and rodents — all of which destroy free-running buried cable inside a few years. Second, it lets future circuits be added or swapped without ripping out walls or trenching the lawn again. Third, it complies cleanly with the current 18th edition wiring regulations for outbuildings, which insist on protected cable runs to anything outside the main building's earthing zone.
On this Sale install we ran the supply from the main consumer unit out through the garden in conduit, terminating into a dedicated sub-board inside the office. Sockets sized for desktop kit, multi-monitor setups, networking, heating where required, and a kettle or small fridge — every circuit on its own RCBO so a fault on one doesn't take the whole office offline. Lighting on a separate switched circuit, internal sockets at proper working-desk height, and sufficient capacity for whatever the room ends up being used for in the next ten years rather than just what fits today.
Garden office work is one of the things we do most across Sale and the wider Trafford / Stockport / south Manchester catchment — the commuter-belt demographic and the work-from-home shift have driven a steady stream of these installs since 2020. If you're building a garden office and you want the electrics specified properly from day one — sub-board capacity, conduit routing, lighting layout, future-proofing — get in touch. The earlier the electrics get planned in (ideally before the slab pours), the cleaner the install runs.
