Good to know

Common questions

General guidance about electricians in the UK, not specific to any one business.

What's the difference between a fuse box and a consumer unit?

A fuse box uses cartridge or rewireable fuses to protect circuits. A consumer unit uses circuit breakers and RCD devices, which trip automatically if there's a fault, then can be reset. Consumer units are safer and more reliable.

Can I fit a socket or light fitting myself?

Any electrical work on fixed wiring in a house must comply with building regulations. Non-notifiable work by a non-qualified person may affect insurance and property sale. Certification from a qualified electrician is the safest route.

How do I know if my house needs rewiring?

Signs include cloth or rubber insulation (pre-1960s), frequent tripped circuits, discoloured sockets, burning smells, or no earth wire to sockets. An electrician can survey the installation and advise whether full rewiring or targeted work is needed.

What's involved in PAT testing?

PAT is a visual check and electrical tests on portable appliances like kettles, computers and power tools. It confirms the earth and insulation are safe. Results are logged and items are tagged with a pass sticker and next test date.

Can any electrician install an EV charger?

EV chargers must be installed by a qualified electrician who understands the building regulations and electrical standards for the charger type. Installation involves a dedicated circuit, safety devices, and correct earthing to the home's system.

Why do my lights flicker or dim?

Flickering can be a loose connection at the light, switch or circuit breaker. Dimming under load may indicate inadequate cable size or a failing neutral connection. Both need checking by an electrician to rule out fire or shock risk.
