How to Find a Trusted Electrician: A Vetting Guide
To find a trusted electrician, verify their licence or registration number against the issuing authority, ask for proof of public liability insurance, request two or three recent references, and collect at least three written quotes that itemise labour, parts and callout. Never pay the full amount upfront.
Electrical work is one of the few home services where a bad hire is not just expensive but dangerous. Faulty wiring is hidden behind plaster, so the consequences of poor workmanship can go unnoticed for years. That makes vetting more important than price shopping. The good news is that the process is systematic: a handful of checks, done in order, filters out almost everyone who should not be near your consumer unit.
Start with the licence, not the price
Every credible electrician holds a licence, registration or certification issued by a competent authority or scheme in their jurisdiction. The number itself is not the proof - the check is. Ask for the number in writing, then look it up directly with the issuing body rather than trusting a certificate photo, a website badge or a logo on a van. Badges are trivially copied. Register entries are not.
When you look up the record, confirm three things: that the number is current and not expired, that the name on the record matches the person or business quoting you, and that the scope of the registration covers the work you need. A registration for one category of work does not automatically cover another.
Insurance, references and written quotes
Proof of public liability insurance protects you if something is damaged or someone is injured during the job. Ask for the certificate, check the policy is in date, and check the insured name matches the trading name on the quote. A subcontractor working under someone else's insurance is a common gap.
References matter more than star ratings because you can ask follow-up questions. Request two to three recent references for jobs similar to yours - a rewire reference tells you little about a fault-finding job. Ask each reference whether the work finished on the agreed date, whether the final invoice matched the quote, and whether the electrician came back to fix anything afterwards.
Finally, get at least three written quotes. A written quote is the single most useful vetting document you will collect, because it forces the electrician to be specific and it gives you something to compare.
What a proper written quote must itemise
| Quote element | What to look for | Why it matters |
|---|---|---|
| Labour | Hourly or day rate, plus estimated hours, stated separately | Lets you compare quotes like for like when parts differ |
| Parts and materials | Named components and quantities, not "materials as required" | Vague material lines are where quotes quietly inflate |
| Callout fee | Stated amount and whether it is deducted from the final bill | Prevents a surprise line on the invoice |
| Who supplies materials | Explicit: you, the electrician, or a mix | Decides who carries the warranty on faulty parts |
| Workmanship warranty | Length and what it covers, in writing | Separates the parts guarantee from the labour guarantee |
| Start and completion dates | Specific dates, not "next month" | Your only leverage if the job stalls halfway |
| Deposit terms | Percentage and what it pays for | A deposit of 10-30% for materials is normal; full payment upfront is not |
| Certification | Whether test certificates or compliance paperwork are included | You may need this documentation when you sell or insure the property |
Any price figures you see are indicative and approximate only, and they vary widely by region, job complexity, access, materials and time of day. Do not treat a number from one quote - or from the internet - as a benchmark. The three-quote rule exists precisely because local rates are the only rates that matter.
Read reviews across more than one platform
A single review site is easy to manage and easy to game. Check at least two independent sources and read for patterns rather than reacting to individual complaints. One angry review about a scheduling clash tells you little. Several reviews spread over many months all mentioning that the electrician disappeared before the snagging was finished tells you a great deal.
Useful patterns to look for: repeated mentions of the final bill exceeding the quote, repeated mentions of missed appointments, repeated mentions of certification never arriving, and repeated mentions of the same named individual doing good work. Also read the electrician's responses. A calm, factual reply to a bad review is a better signal than a wall of five-star ratings with no detail.
Red flags that should stop the conversation
| Red flag | What it usually signals | Your response |
|---|---|---|
| Cash-only demand | No paper trail, likely no insurance or registration | Decline and move on |
| No written quote | Price can be revised after the work starts | Ask once in writing; if refused, walk away |
| Pressure to decide immediately | Sales tactic designed to stop you comparing | Say you are collecting three quotes and see how they react |
| Price far below every other quote | Corners cut, scope misunderstood, or a bait figure | Ask what is excluded; expect vagueness |
| No fixed business address | Nowhere to pursue a claim or a warranty | Require a verifiable address before any deposit |
| Full payment demanded upfront | Cash-flow problem or no intention of returning | Offer a 10-30% materials deposit only |
| Reluctance to give a licence number | Not registered, or registered under a different name | End the conversation |
| References refused | No recent completed work to point at | Treat as disqualifying for anything beyond a minor job |
A practical order of operations
- Write a one-paragraph scope of the job so every electrician quotes the same thing.
- Shortlist candidates from a vetted local directory and from personal recommendations.
- Ask each for a licence or registration number and check it with the issuing authority.
- Request proof of public liability insurance and confirm the dates and the insured name.
- Ask for two to three references for similar recent jobs, and actually call them.
- Collect three written, itemised quotes with start and completion dates.
- Cross-check reviews on two or more platforms and look for repeated themes.
- Agree the deposit in writing, keep the balance until the work is signed off, and get your certification.
Emergency call-outs: shortcut the process safely
You will not run an eight-step vetting process at 11pm with a tripping circuit. Compress it: ask for the licence number over the phone and check it while they travel, confirm the callout fee before they leave their depot, and insist on a written quote for any remedial work beyond making the situation safe. Making safe and repairing are two separate jobs - do not let them merge into one open-ended bill.
Keep the paperwork
Store the quote, the invoice, the insurance certificate, the licence number and any test or compliance certificates together. Buyers, insurers and future electricians all ask for this, sometimes years later. If something goes wrong, this folder is the difference between a claim and an argument.

Frequently asked questions
How many quotes should I really get?
At least three. Two gives you no way to tell which one is the outlier. Three lets you spot both the inflated quote and the suspiciously low one, and it usually reveals differences in scope that you had not thought to specify.
Is a deposit ever reasonable?
Yes. A deposit of 10-30% to cover materials is normal practice, particularly on larger jobs where the electrician has to buy cable, boards or fittings before starting. What is not normal is being asked for the full amount before any work is done.
What if the only good reviews are on the electrician's own website?
Treat testimonials published by the business as marketing, not evidence. Check independent platforms - more than one - and weigh patterns across them. If an electrician has no traceable presence anywhere outside their own site, ask for references instead and verify those directly.
Should I supply the materials myself?
Only if you have agreed it in writing and you understand the warranty consequences. If you supply a faulty fitting, the electrician is unlikely to cover the cost of returning to replace it. Most homeowners are better off letting the electrician supply materials and carry that risk.
What do I do if the work has already gone wrong?
Put your complaint in writing, referencing the quote and the agreed dates, and give a reasonable deadline to fix it. Keep paying nothing further until it is resolved. If the electrician is registered with a scheme or authority, that body is usually your next escalation route. You can also get in touch with us for help finding a qualified electrician to assess and document the existing work.
