My RCD keeps tripping — what should I do? +
An RCD that keeps tripping is detecting an earth leakage fault, which could be a sign of damaged wiring or a faulty appliance. Start by unplugging all appliances on the affected circuit, then reset the RCD. Plug each appliance back in one at a time to identify the culprit. If the RCD trips with nothing plugged in, the fault is in the fixed wiring and you need an electrician in Ashburton to trace and repair it.
Why do my lights flicker in Ashburton? +
Occasional flickering is usually caused by a loose bulb or a poor connection at the light fitting. Persistent flickering across multiple lights can indicate a loose neutral connection at the consumer unit, a faulty main switch, or an issue with the incoming supply. If all lights in your home flicker simultaneously, this could be a supply-side issue — contact your DNO first. Otherwise, have an electrician in Ashburton check the connections at your consumer unit.
Will the electrician give me a quote before starting work? +
Yes — a professional electrician will diagnose the fault and provide a clear quote before beginning any repair work. For emergency call-outs, they will explain the call-out fee upfront and then quote for the repair once the fault has been identified. You should receive a Minor Electrical Installation Works Certificate or full Electrical Installation Certificate depending on the scope of the job.
What is the difference between an RCD and an MCB? +
An MCB (Miniature Circuit Breaker) protects against overcurrent and short circuits — it is the modern equivalent of a fuse. An RCD (Residual Current Device) protects against earth leakage, which is what can kill you if you touch a live wire. Modern consumer units use RCBOs, which combine both functions into a single device per circuit, giving you the best protection. If your consumer unit still has rewirable fuses, it is overdue for an upgrade.
Can I do any electrical work myself? +
You can legally carry out minor electrical work such as replacing light switches, sockets (like-for-like), and light fittings without notifying building control. However, you must not add new circuits, work in bathrooms or kitchens (within zones), replace a consumer unit, or install outdoor wiring unless you are Part P registered. DIY electrical work is a leading cause of house fires — if you are unsure, always call a qualified electrician in Ashburton.
What is Part P and why does it matter? +
Part P of the Building Regulations covers electrical safety in dwellings. Certain types of electrical work — including new circuits, consumer unit replacements, and work in bathrooms or kitchens — are classed as notifiable and must either be carried out by a Part P registered electrician or inspected by building control. Using a registered electrician saves you the building control fee (typically £200–£300) and ensures the work is properly certified.
