Before you hire an electrician, know what qualifications to check, what questions to ask, and what to watch out for to avoid unsafe or uncertified work.
Electrical work is one of the few areas of home improvement where hiring the wrong person does not just lead to a poor finish. It can create a genuine safety risk. A badly wired circuit can cause fire, electric shock, or appliance damage, and uncertified work can cause problems when you sell your home. Knowing what to look for when choosing an electrician makes the whole process simpler and much safer.
This guide covers the qualifications to check, the questions worth asking upfront, and the signs that should make you think twice before proceeding.
In England and Wales, most electrical work in a home is covered by Part P of the Building Regulations. This means electricians carrying out notifiable work must either be registered with a competent person scheme or notify the local authority before starting and arrange for an inspection afterwards.
The main competent person schemes for electricians are:
Any electrician registered with one of these schemes can self-certify their work and issue you an Electrical Installation Certificate (EIC) on completion. This is the document that proves the work was done to the current wiring regulations (BS 7671) and is important when you sell your property.
You can verify a contractor's registration at niceic.com or napit.org.uk before any work starts. Do not take their word for it, check the register directly.
Look for electricians holding:
A qualified, registered electrician should be able to tell you exactly which qualifications they hold. If the question makes them uncomfortable, that tells you something.
If yes, which one? Can you provide your registration number so you can check it online?
For any notifiable work, this is not optional. If an electrician is reluctant to certify their work, decline the job.
Ask for the insurer's name and policy number. A professional electrician should have at least £1 million in public liability cover.
Find out whether materials are included or charged separately, whether the price covers making good (filling walls or ceilings after chasing cables), and whether the certification fee is included in the quote.
Consumer unit upgrades, EV charger installations, and rewires are all quite different jobs. A good electrician will have relevant recent experience for your specific type of work.
For anything more than a minor repair, get at least two or three quotes. Prices for electrical work vary, and some electricians charge significantly more than others for the same job without any corresponding difference in quality. Written quotes allow you to compare like for like and spot if one contractor has left something out.
When comparing quotes, check that each one covers the same scope of work. A quote that excludes certification, making good, and materials can look cheaper but end up costing more once everything is added.
If you are moving into an older property, buying a buy-to-let, or have not had your electrics checked in ten years or more, an EICR is worth having. This is a full inspection of your existing wiring and consumer unit, resulting in a report that grades any defects. An EICR costs £150 to £300 depending on property size and is a good starting point before any upgrade work.
Landlords are legally required to have an EICR carried out every five years or at the start of a new tenancy.
