Rewiring an existing home

Most rewires are carried out without major disruption to the home. Cable is run through the roof space and underfloor, and where removing old wiring would damage the walls, it is safely disconnected and left in place.

Every home is assessed on site first. Slab floors, subfloors and older switchboards each affect how the job is done, and all of it is set out in the written quote before any work begins.

Roof space
Wiring from above
Through the ceiling space and down inside the walls to each outlet and switch.
Underfloor
Wiring from below
Where there is a subfloor. On a slab the options differ, and they are explained at the quote stage.
Switchboard
Switchboard upgrade
Old fuses replaced with modern breakers and RCDs, with every circuit labelled.
Walls
Wall repairs included
Openings are kept small and few, and any wall repairs are included in the quote before work begins.
Living areas
Staged power outages
One circuit at a time where possible, so the fridge and hot water stay on. A full rewire can also be staged over several weeks.

New builds

Each stage is completed in order and on schedule, so the builder and the trades that follow are never held up.

A long open service trench beside a driveway, spoil heaped along it and marker tape run out, the HG van open at one end and a digger up at the scaffolded new build — Before the slab
Underground supply, before the pour
Trenching, ducting and the supply from the road, installed and covered before the concrete is poured. We work from the builder's set-out and levels, so nothing needs cutting out of the finished floor.
