Electricity is the one trade where mistakes can genuinely threaten a home. A poor plumbing job leaks, but a poor electrical job can start a fire, which is why hiring a qualified, properly insured electrician matters more than saving a few pounds on the quote. This guide walks you through finding someone trustworthy, checking they are legitimate, comparing quotes fairly and knowing what a reasonable price looks like in 2026.

Step 1: Know What You Need
Before you search, be clear about the job. Is it a like-for-like repair, a new circuit, a consumer unit upgrade or a full rewire? The answer changes who you need and what you should expect to pay. Small jobs like replacing a socket can be done by a local electrician on an hourly rate, while a rewire is a multi-day project that needs planning and possibly building regulations notification.
It also helps to know what you do not need. In the UK, only certain work is legally restricted to a registered electrician, mostly under Part P of the Building Regulations: work in bathrooms, new circuits, consumer unit changes and anything near outdoor structures. Simple like-for-like swaps elsewhere may not require registration, but a professional will still do the job properly and certify it.
Step 2: Search the Right Way
A plain search for electricians near me returns thousands of results, and price comparison sites sell leads to whoever pays, not whoever is best. A directory with vetting changes the odds. TrustATrader only lists traders who have passed checks on their qualifications, references and experience, and every profile carries verified customer reviews, photos and videos of previous work, so you can see real jobs before you make contact.
When you search, look for electricians who cover your area and list the specific work you need. An electrician who specialises in rewires or consumer units is a better fit for a big job than a generalist, and their profile will tell you.
Step 3: Check Their Credentials
Before you book anyone, confirm three things:
- They are qualified. A competent electrician should hold a recognised qualification such as City and Guilds or an NVQ in electrical installation, and be up to date with the 18th Edition wiring regulations.
- They are registered. For notifiable work, your electrician should be registered with a competent person scheme such as NICEIC or NAPIT, which lets them self-certify work and notify building control on your behalf.
- They are insured. Public liability insurance of at least £1 million is the standard expectation, and a professional will not mind you asking for proof.
You can also ask for references or examples of similar work. A reputable electrician has done this dance before and will be happy to show evidence. Anyone who is evasive about qualifications or insurance should be a hard no, no matter how good their price is.
Step 4: Know the Jobs That Need a Registered Electrician
Under Part P of the Building Regulations, certain electrical work must be carried out by a registered electrician or notified to building control. That covers most work in bathrooms, replacing or installing a consumer unit, adding new circuits, and anything near a pool or outdoor structure. A registered electrician can self-certify this work and notify building control on your behalf, which keeps everything legal and saves you the paperwork.
If you are buying a home or have not had the electrics looked at in over ten years, an Electrical Installation Condition Report (EICR) is worth considering. It is a formal inspection of your wiring, sockets and consumer unit that flags anything deteriorated or not up to standard. It is legally required for landlords, and for homeowners it is the sensible way to know the real condition of your electrics before you start spending.
Step 5: Get and Compare Quotes
Get at least three quotes for any job worth more than a couple of hundred pounds. A proper quote describes the work, the materials, the timescale and the price, and it lets you compare fairly. Be wary of a quote that is dramatically cheaper than the others, because it usually means something is missing, whether that is certification, insurance or the actual scope of work.
Step 6: Ask the Right Questions
Before the work starts, confirm the essentials in writing:
- What exactly is included in the quoted price, including materials and VAT
- Whether the work will be certified and how you will receive the certificate
- The start date, expected duration and what happens if the job overruns
- Whether the work is notifiable under Part P and who handles building control
- How they handle problems after completion, and whether they offer a warranty on their work
A professional electrician expects these questions and answers them clearly. Vague answers are a red flag.
Step 7: Protect Yourself Before and After
Agree a sensible payment schedule. Avoid paying the full amount up front, and be suspicious of anyone demanding a large deposit before work starts. A reasonable approach for a big job is staged payments tied to progress, with the balance on completion.
When you have agreed the job with a TrustATrader trader, register it for the TrustATrader Guarantee free of charge. It covers agreed work up to £1,000 per claim if the standard of work falls short, which gives you a real remedy if something goes wrong. After the job, leave a review: it helps the next homeowner and keeps the directory honest.
Red Flags to Walk Away From
Trust your instincts when something feels off. Walk away from any electrician who cannot show proof of qualifications or insurance, demands cash payment in full up front, has no verifiable reviews, or quotes a price far below everyone else. A genuinely reliable tradesperson has nothing to hide and will happily show you their credentials and their past work.
