Plain-English electrical advice

Practical answers to the questions Cameron gets asked most often — no jargon and no scare tactics.

Why does my fuse board keep tripping?

A breaker that trips once may just be a failing appliance. A breaker that trips repeatedly is telling you something is wrong on the circuit — usually a damaged cable, water where it shouldn't be, an overloaded circuit, or an appliance with a deteriorating element.

The safe order is: unplug everything on that circuit, reset once, then reintroduce appliances one at a time. If it trips with nothing plugged in, the fault is in the fixed wiring and needs testing properly rather than repeated resetting.

Electrical fault finding

Does my old fuse board need replacing?

Rewireable fuses, a wooden back box, no RCD protection or an older board are all good reasons to have the installation assessed — none of them means on its own that a replacement is required. Age alone does not make an installation unsafe.

Where it is appropriate to the installation, a modern consumer unit can include RCD or RCBO protection, which disconnects the supply fast enough to protect a person rather than only the cable. What is suitable depends on the circuits themselves, which is why inspection and testing comes before any recommendation.

What is an EICR and do I need one?

An Electrical Installation Condition Report is a formal inspection and test of the fixed wiring, with findings recorded as C1 (danger present), C2 (potentially dangerous), C3 (improvement recommended) or FI (further investigation).

Rented homes in England need one at least every five years. Owner-occupied homes are generally recommended every ten years, or sooner before buying, renovating or selling.

EICRs & electrical testing

Signs a house may need rewiring

Rubber or fabric-covered cable, round-pin sockets, no earth at the lighting points, a very small number of sockets per room, or persistent unexplained faults across several circuits all point towards installation age rather than a single defect.

Many houses only need a partial rewire — the original circuits replaced where they have degraded and the sound ones retained. Testing first is what separates a targeted job from an unnecessary full rewire.

Choosing downlights without regretting it

Get the colour temperature right first: around 2700K for living rooms and bedrooms, 3000K–4000K for kitchens and bathrooms. Mixing temperatures across one open-plan space is the most common regret.

Then think about zones and dimming before the holes are cut — fire-rated fittings where they penetrate a ceiling, IP-rated fittings in bathrooms, and dimmable drivers matched to the switch.
