Common questions
General guidance about electricians in the UK, not specific to any one business.
What is an RCD and why do I need one?
An RCD (residual current device) cuts power instantly if it detects someone touching a live wire or a fault occurring. Modern building regulations require RCDs on all circuits. They prevent serious shocks and electrocution—essential protection in kitchens and bathrooms.
Can I install my own sockets and lights?
DIY alterations to fixed wiring breaches Building Regulations and safety law. Any change to circuits must be done by a qualified electrician and certified. This protects occupants and is essential for property sale, insurance, and legal compliance.
What does PAT testing involve?
PAT (portable appliance testing) checks portable equipment for electrical safety. A technician visually inspects leads and plugs, then uses test equipment to verify earthing, insulation, and safety. Results are recorded and appliances labelled with test date and pass/fail status.
Is it expensive to upgrade an old fuse box?
Consumer unit replacement is a single job with clear scope and labour time. Cost varies by property access, cable condition, and number of circuits needed. Many properties can upgrade affordably. It's a fixed investment that improves safety and often enables new circuits.
What should I check before calling an electrician?
Note which outlets or lights are affected, when problems started, and any burning smells or sounds. Have your property age and council tax band handy. Take photos of damaged sockets or switches. This information helps the electrician diagnose faster.
