Big loads, old boards
Do I need a new fuse board to fit an EV charger?
Often, yes. A 7kW home charger needs its own dedicated circuit, the right type of RCD protection, and a spare way on the board. Old boards usually offer none of the three. That is why charger installers look at your board photo before they will book you in.
The same logic applies to electric showers. A 10.5kW shower pulls more than 40 amps continuously, more than an entire 1970s house was designed around.

What an EV-ready board gives you
Same fixed packages as every other job. We fit the board; your charger installer fits the charger, or we can recommend one we work with.
✓Spare ways, sized for big loadsAt least two free slots with the capacity for a 32A or 40A circuit, so the charger or shower connects without another board change.
✓The right protection typeEV circuits need RCD protection that handles DC leakage, usually Type A with the charger’s built-in protection. We spec the board so any compliant charger just drops on.
✓Headroom on the supplyWe check your main fuse and tails as part of the job. If the supply itself needs the network operator involved, we tell you before anything is committed.

Often, yes. A 7kW charger needs a dedicated circuit with the right RCD type and a spare way on the board. Old boards usually have neither, which is why many charger installers will quote for the charger only once the board is sorted.
A modern 9.5kW to 10.5kW shower draws more than 40 amps on its own. It needs its own circuit, properly protected. If your board is an old rewireable box or has no spare ways, the board comes first.
Do the board first or together. Doing it first means any installer can then fit the charger without surprises, and the power is only off once.
A metal consumer unit with RCBOs, surge protection and at least two spare ways sized for high load circuits, so a charger or shower can be added later as a small job.
