Common faults
- An RCD that trips repeatedly — usually moisture, a failing appliance, or degraded cable insulation somewhere on a shared circuit
- Dead sockets or a dead ring — often a loose connection behind a faceplate or in a junction box
- Flickering or buzzing lights — loose terminations, incompatible dimmers, or failing LED drivers
- Outdoor circuits tripping after rain — water ingress into an outdoor socket, garden light or shed supply
- Intermittent faults
How faults are traced
Faults are traced by systematic testing. We split the installation down circuit by circuit, test insulation resistance and continuity, and narrow the fault to a section, then to a point.
Quick checks
First, unplug everything on the affected circuit, reset the breaker, then plug items back one at a time. A surprising number of "electrical faults" turn out to be a failing kettle, a water-damaged outdoor light, or a freezer on its way out.

Questions we get asked
Before you call.
Why does my fuse board keep tripping?
Usually a faulty appliance, moisture in an outdoor circuit, or deteriorated cable insulation. Unplug everything on that circuit and reset — if it holds, reintroduce appliances one by one.
How long does fault finding take?
Straightforward faults are often traced within an hour or two. Intermittent or weather-dependent faults take longer because they have to be reproduced before they can be located.
Do you charge to find the fault and again to fix it?
We're clear about both up front. You get a price for the diagnosis, and once we know what's wrong, a fixed price for the repair before we do it.
My lights flicker but nothing trips — is that serious?
It can be. Flickering often means a loose connection, and loose connections generate heat.
