What is included in small electrical works?
Small electrical works cover short domestic jobs such as adding a socket, replacing a light fitting, wiring an extractor fan or tracing a fault. The work may be small in size, but the electrician still needs to check that the existing circuit can safely support the alteration.
Signs you need small electrical works
- You need extra double sockets or USB charging points near furniture and desks
- A ceiling light, dimmer or switch needs replacing with a compatible fitting
- An extractor fan needs a suitable supply, isolation or replacement
- A circuit trips, a socket has stopped working or a fixed appliance needs connecting
What the electrician may do
- Check the existing circuit, protective devices, earthing and bonding before extending it
- Agree socket positions and cable routes, then protect floors before lifting boards or chasing walls
- Fit suitable back boxes, accessories, fused connection units or fan isolators as the job requires
- Test the alteration, explain any existing defects, clear installation debris and issue the appropriate paperwork
An electrician should check LED driver and dimmer compatibility, suitable bathroom and outdoor protection, and the condition of the circuit being altered. Adding a socket does not automatically mean a new consumer unit is needed. If an issue is uncovered, ask for its test evidence and a separate explanation of the options.
What to include when asking for a quote
List each fitting and room, say whether you are supplying accessories, and mention dimmable LEDs, bathroom zones or outdoor positions. Send photographs of closed fittings only. Ask whether patching chases, decoration and disposal are included, and whether several jobs can be combined into one visit.
What does small electrical works cost?
The indicative UK guide range is £80–£500. It is a budgeting allowance rather than a guaranteed quotation. Ask for the total payable, including VAT where applicable, and a clear list of exclusions.
The number of fittings, cable distance and wall construction matter more than the size of the faceplate. Flush sockets in solid brick take longer than surface fittings. Fault finding may be charged by time because the cause is not known at the start; agree a visit fee and an authorisation limit for further work.
Checks, testing and documents
Ask who will inspect and test the work, which electrical certificate is included and who handles any building-control notification. Approved Document P for England explains England’s notification rules. Wales has its own Part P guidance; Scotland and Northern Ireland have different building standards arrangements. The job and its location determine the route, so agree it before work begins.
Companies joining the network are asked to provide relevant insurance details and references. Before booking, check current insurance, relevant experience and registration for the work yourself. Electrical Safety First’s electrician register can help you check a business’s listed scope. A listing or introduction does not replace agreeing a written specification with your chosen electrician.
Questions homeowners ask
Can I supply my own light fittings in the UK?
Usually, provided the electrician confirms that each fitting is suitable for the circuit, location, weight and mounting surface. Agree in advance who is responsible if a customer-supplied fitting is faulty.
Will a small alteration need a certificate?
An addition or alteration to an existing circuit may use a Minor Electrical Installation Works Certificate. New circuits require an Electrical Installation Certificate. A simple like-for-like replacement is different; ask which testing and records are appropriate for your particular job.
How should I describe an intermittent fault?
Say which circuit or appliance is affected, what happens and when it started. Do not open accessories or recreate a dangerous fault for a photograph. Agree how diagnostic time and any subsequent repair will be charged.
Can several small jobs be quoted together?
Yes. List every socket, switch, light and fan you want checked or changed, with the room and intended position. Combining visits may reduce repeated call-out costs, but the electrician needs to assess the whole list.
