What should I do if I have a complete power cut in Leicester? +
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 Leicester as there may be a serious fault on one of your circuits.
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 Leicester.
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.
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.
How long does a consumer unit replacement take? +
A consumer unit replacement in Leicester usually takes 4 to 8 hours, depending on the number of circuits and the condition of the existing wiring. Your electricity supply will be off for most of this time, so plan accordingly — charge phones, fill flasks, and move any frozen food to a cool bag. The electrician will test every circuit before restoring power.
What should I do if a socket is sparking? +
Stop using the socket immediately and switch off the circuit at the consumer unit. Sparking when plugging in can sometimes be normal (a brief blue flash), but persistent sparking, blackening around the socket, or a crackling sound indicates a serious wiring fault. Do not attempt to remove the socket faceplate yourself — call a qualified electrician in Leicester to inspect and repair it safely.
