What happens on the day
We inspect your existing fuse box before replacing it at your Clapham property. A consumer unit is the box that distributes electricity and protects each circuit. The work moves from initial checks to disconnection, fitting and testing.
- What gets checked before the fuse box comes out?We examine the board, incoming electricity supply and connected wiring. We check earthing, the protective connection that carries fault current, and bonding, which connects metal gas and water pipes to the earthing system.
- When is the power disconnected?We disconnect the incoming electricity before removing the old fuse box. The supply stays off while we fit the replacement and connect the property's circuits.
- What replaces the old fuse box?We fit a metal consumer unit containing individual protective switches. We connect the existing circuits and mark the switches to identify the rooms or appliances they control.
- How is the replacement tested?We test the connected wiring and check that the protective switches operate correctly. Checks take place before and after power returns, and your electrical installation certificate records the test results.

Can you replace my fuse box in Clapham?
We replace fuse boxes at properties in Clapham. Our consumer unit replacement includes fitting modern protective switches and testing the wiring connected to them.
What happens at my property after booking?
We begin the replacement visit by examining your fuse box, supply connections and existing circuits. We then disconnect the electricity, change the board and test the completed installation.
How long will the replacement work take?
Most domestic fuse box changes take four to six hours. The number of circuits connected to the board affects the time needed for fitting and testing.
Will my electricity be off while you change the board?
Your electricity stays off while we remove the old board and wire its replacement. We restore the supply after the initial safety tests, then complete further checks with power on.
What happens if testing finds damaged wiring?
We explain the wiring fault and the repair it needs. Repairs to existing circuits are separate from replacing the fuse box.
