Can you install additional circuits for a small job?

What is involved in a consumer unit replacement?

Replacing a consumer unit includes isolating power, fitting the new unit, connecting circuits and testing. Your Electrician should explain what protection devices are included and provide certification where required. It helps to note any existing issues, recent work, and the areas involved.

Is a safety check the same as an EICR?

An EICR is a formal safety inspection of fixed wiring and circuits. It checks for defects and compliance issues. A general safety check may be less detailed, so ask which report you will receive. Ask what is included, how long the work may take, and what happens if extra issues appear.

Will the work be disruptive?

Some jobs are quick, while others involve access to walls or floors. an electrician can explain the expected disruption and whether any making good will be needed after cables are run. Photos and measurements can help the Electrician give clearer guidance.

Do you need to see the property before quoting for a small job?

For simple jobs, a clear description and photos may be enough. For larger work such as rewires or new circuits, a site visit helps the Electrician provide an accurate scope and timeline. If relevant, confirm how services will be isolated and when they will be restored.

Can you fit extractor fans or bathroom electrics?

Yes, many electricians install extractor fans and bathroom fittings. Electrical work in bathrooms needs careful planning and suitable protection, so ask how the installation will be designed. Share the age of the property, access, and what you want to change so the Electrician can plan the right approach.
