Electrcial jobs: trader tips
In addition to the pricing and completion time information, the recommended electricians who particpated in our survey also shared some helpful advice.
Most job prices include testing and certification.
Jobs are more straightforward in new houses where existing wiring and fittings already meet regulations. In older houses, work may be more costly and time-consuming.
Job: replace light fitting
Many electricians will have a minimum charge (often the rate for one hour) for small jobs like this. It could work out more cost effective to get them to do several jobs at once.
Some electricians will charge a call-out fee for small jobs.
Job: perform an electrical inspection report
Time taken will usually include an inspection of the property plus one or two hours in the office to write up the report.
Job: replace consumer unit
A good trader will usually include full testing with all installations.
If any faults are found during testing it could take extra time to diagnose problems and fix them.
Job: install electric shower
Fitting an electric shower requires electrical and plumbing skills. Some electricians are qualified to do plumbing work so have included this in their costs. Others are only qualified to do the electrical installation so you would need to employ a plumber separately.
Job: install a light in loft
This job is made easier if the loft is not boarded out as wiring can be accessed more easily.
Job: install two extra double sockets in lounge
Expect to pay at the higher end of the range if you want wires 'chased' into walls (hidden). Bear in mind that this will take longer and may require plastering afterwards. Surface trunking is quicker and cheaper but won’t look as good.
Job: replace standard light switch with dimmer switch
Minimum charges may apply to a small job such as this. It would work out more cost effective to have several small jobs done at once.
Job: repair a damaged power cable on vacuum cleaner or other similar appliance
Not all electricians undertake appliance repairs so you may need to find a specialist appliance repairer. Call-out fees may apply as this is a small job.
It will take much longer to rewire an occupied house than an empty one.
Rewiring usually takes at least two people. If more staff are used, it may be done more quickly but costs (total man hours) are likely to be the same.
In July 2012 we sent a survey to all Which? Local traders in the Electricians category with a rating of three stars or more and an email address.
110 electricians responded to the survey. Using their experience and expertise, they answered questions about the cost of popular domestic electrical jobs, and how long they should take to complete.
