What should I do if I have a complete power cut in Braintree? +
First, check whether your neighbours also have no power — if so, it is likely a supply fault and you should call your local distribution network operator (DNO), not an electrician. If it is only your property, check your consumer unit for tripped switches. If the main switch will not stay on, or keeps tripping immediately, do not keep resetting it — call an emergency electrician in Braintree as there may be a serious fault on one of your circuits.
Do I get a certificate after electrical work is completed? +
Yes — for any notifiable electrical work (new circuits, consumer unit replacements, bathroom/kitchen installations), your electrician must issue an Electrical Installation Certificate and notify your local building control. For smaller jobs like replacing a socket or light fitting, you should receive a Minor Electrical Installation Works Certificate. Keep these certificates safe as you will need them when selling your property.
Why do my lights flicker in Braintree? +
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 Braintree check the connections at your consumer unit.
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 Braintree.
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 Braintree to trace and repair it.
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.
