Good to know
Common questions
General guidance about electricians in the UK, not specific to any one business.
What is the difference between a fuse box and a consumer unit?
A fuse box uses replaceable fuses that melt to cut power. A consumer unit uses MCBs or RCBOs—switches that trip automatically. Consumer units offer better safety and respond faster to faults.
Do I need a qualified electrician to install a new socket?
Yes. Any work on fixed wiring must be carried out by a qualified electrician and tested. Plugging things into existing sockets is fine, but installing or moving sockets requires professional work.
Why do my lights flicker or dim when I use the kettle?
Heavy appliances like kettles draw large amounts of power, causing voltage to drop briefly. This suggests your circuits may be overloaded or the supply is undersized. An electrician can assess and recommend upgrades.
How often should PAT testing be done?
Frequency depends on equipment type and workplace. High-risk items like extension leads in kitchens may need testing annually. Low-risk equipment like desk fans might only need testing every two years.
Can I install an EV charger myself?
No. EV chargers must be installed by a qualified electrician and connected to a dedicated circuit with an isolator switch. Improper installation can damage the vehicle or create fire hazards.
What does rewiring a house actually involve?
Rewiring means replacing all the electrical cables running through walls, ceilings and floors. Old cables are removed, new routes are planned, cables are installed in safe conduits, and new sockets and switches are fitted throughout.
