Fuse Box Replacement in South Malling

One RCD, a lot of circuits
Homes built in the middle of the last century usually began with rewireable fuses. Many were later given a split load consumer unit, where one RCD guards the sockets and the lighting has none, or one RCD covers almost everything. Both were reasonable in their day, but neither meets current expectations, and a single trip can switch off a large part of the house.
Replacing that board with a full RCBO unit gives each circuit its own protection. Prices are £625 for 8 ways and £695 for 10 to 12 ways, sizes that cover most family houses here. On a tighter budget, £575 buys a 12 way high integrity board with two RCDs.
- Split load boards replaced
- Lighting brought under RCD protection
- Full RCBO boards from £625
- High integrity option at £575

Finding out why the power keeps going off
An RCD that trips at random, often in wet weather or when a certain appliance switches on, is a frequent complaint in houses of this age. With older wiring and one RCD guarding many circuits, small leakages add up until it trips, and the culprit is hard to pin down. Fitting a new board without finding the cause does not cure it.
Before swapping the board we test the insulation of every circuit, which usually reveals the problem: an outdoor socket, a damp light fitting or a tired immersion heater. We put right what we find, or explain the cost first. On the new RCBO board, any later fault trips only its own circuit.
- Insulation tested circuit by circuit
- Outdoor and damp fittings checked
- Faults explained before fixing
- One fault, one circuit off
Through the tunnel and up the A26
The drive from Brighton & Hove follows the A27 to Lewes and then the A26 north through the Cuilfail tunnel, which points us straight at South Malling. A handful of fuse box photos is enough for us to quote you a set figure. If the power has gone and will not reset, give us a call; same day attendance is often possible.

Asked in South Malling
Call for a straight answer from an installer, not a call centre.
Call 0333 360 8691An RCD that trips is doing its job, detecting current leaking where it should not. If it resets and holds, the fault may be intermittent, such as moisture in an outdoor fitting. It is still worth having tested, because a growing fault can leave you without power at a bad moment, or point to a cable that is deteriorating.
A dual RCD board splits the circuits into two groups, each behind one RCD, so a fault switches off a whole group. A full RCBO board gives every circuit its own combined breaker and RCD, so only the faulty circuit goes off. Dual RCD boards start at £425 and full RCBO boards at £625 for 8 ways. For a busy family home with lots of circuits, we would usually suggest RCBO.
Not usually for a straightforward board change, since the work happens at the board and every circuit is tested from there. If testing points to a fault on a particular circuit, we may need to look at fittings, the loft or an outbuilding to trace it, and we always ask before going anywhere beyond the board.
