Frequently Asked Questions

What does an electrical contractor do?

An electrical contractor manages the design, installation, and maintenance of electrical systems. They handle project management, hold insurance, and take legal responsibility for the work.

When should I call an emergency electrician?

You should call an emergency electrician if you notice signs of immediate electrical danger or a total loss of power. Delaying repairs in these situations can lead to fires or electrical shocks.

Why does my circuit breaker keep tripping?

A circuit breaker trips to cut off power and prevent electrical fires. It is usually caused by a circuit overload, a short circuit, or a ground fault.

How do I know if my house needs rewiring?

You should consider a rewire if your property is over 25 years old or has an outdated fuse box. Look for persistent signs like flickering lights, frequent tripping, or discoloured sockets.

Can any electrician install an EV charger?

No, you should only hire an electrician with specific EV installation qualifications. They must understand complex earthing requirements and meet current Smart Charging Regulations.

How often do landlords need an electrical inspection?

Landlords in the UK must have an electrical inspection every five years or at the start of a new tenancy. This inspection produces an EICR to prove the property is safe for tenants.
