Sutton outbuilding price
The cost is the work inside a detached Sutton building and the test of the cable that feeds it. The house, including an Arts and Crafts house in the Sutton Garden Suburb, is not on this cost. When the feed fails, the armoured run is written separately.
From £450
Included
- A supply from the house into the shed, summerhouse or garden room
- Lights and sockets inside the building
- A fuse board in the outbuilding when the circuits need one
- Testing of the new work
- The installation documents the job requires
Ways to pay


- Pay by bank
- Bank transfer
- Lining, insulation and carpentry stay with the builder.
- Garden lights past the building are another visit.
- Cheam Road flats are not given an outbuilding price when no detached building is there.

We serve Sutton from our base in Banstead.
What happens on the day
Work inside a detached building starts with the cable that already feeds it, and that cable is tested before reuse. An Arts and Crafts house in the Sutton Garden Suburb is the house, not an outbuilding. A 1930s house in West Sutton that wants more sockets is still the house. Cheam Road flats on a shared supply are not given an outbuilding they do not have. A new feed, if the old cable fails, is the armoured job.
- Confirm the building is detachedThe visit is inside a detached building at the Sutton address. The house itself, whether a centre semi or a Garden Suburb house, is not priced on this list.
- Test the feedThe cable that already feeds the building is tested before it is reused. A socket that works inside is not spare capacity. A failed cable is the armoured feed, written as that job.
- Do not invent one for a flatCheam Road flats above the shops are not quoted an outbuilding. The shared supply does not create a detached building behind the parade.

Book NowPhotos of our work
Is a Sutton Garden Suburb house an outbuilding?
No. It is the house. Cable there is planned around the building, and that work belongs to the house, not to an outbuilding list.
Can the old feed be reused?
Only if the test passes. A working socket in the building is not spare capacity for a new load, and a failed cable is quoted as a new feed.
Do West Sutton socket wishes belong here?
No. 1930s houses that want more sockets than they were built with are a house job. This list is a detached building.
Will you add an outbuilding price to a Cheam Road flat?
No. Those flats are above the shops on a shared supply. An outbuilding is quoted only when one is actually there.
Is a rear room of a centre semi included?
No. A room of the house is the house, including where the semi was rewired in stages. Detached means detached.
