Hiring an electrician is one of those decisions that can feel daunting if you've never done it before. Get it right, and you'll have safe, compliant electrical work that lasts decades. Get it wrong, and you could face costly remedial work, safety hazards, or worse—insurance complications if something goes catastrophically wrong.
The average cost of fixing poor electrical work runs into hundreds or thousands of pounds. More importantly, faulty electrics cause around 20,000 house fires annually in the UK. This isn't about being paranoid; it's about knowing what to look for so you can hire with confidence.
The good news? Asking the right questions upfront takes most of the guesswork out of the process. This guide walks you through exactly what to ask—and why it matters.
Before we get to the questions, let's cover the baseline. In the UK, electricians don't need a single national licence, but they should hold recognised qualifications and be registered with a competent body. Here's what matters:
Any electrician worth their salt will have at least NICEIC or ELECSA registration plus Part P certification. Don't accept "I've been doing this for 30 years" as a substitute for current accreditation.
This is your first filter. A yes (backed by verifiable credentials) means they're insured, regularly assessed, and held to professional standards. A hesitant answer or deflection is a red flag. Ask them to provide their registration number so you can verify it independently.
Never accept a vague verbal estimate. A proper quote breaks down labour, materials, call-out fees, and timescale. It gives you transparency and something to compare fairly against other quotes. If they won't put it in writing, walk away.
This protects you if something goes wrong during the work. Minimum cover should be £1 million for domestic work. Request a copy of the insurance certificate—don't just take their word for it. If they're uninsured and cause damage, you're liable.
Professional electricians typically guarantee their labour for 12 months and parts for the manufacturer's warranty period. Anything less is concerning. Get the guarantee details in writing, including what's covered and the process for claims.
There's nothing inherently wrong with subcontractors, but you have the right to know. If they're using someone else, you need assurance that person is equally qualified and insured. You're hiring them ultimately, so they're responsible for quality.
For any work that affects your installation, a proper electrician issues an Electrical Installation Condition Report (EICR) or Minor Works Certificate. This proves the work is compliant and is essential for insurance claims and future house sales. If they can't or won't provide this, that's a major red flag.
A long registration history suggests reliability. For complaints, ask directly but also check their profile on the notified body's website—many allow you to search for complaints history. A couple of resolved issues over years is normal; multiple unresolved complaints isn't.
Listen for whether they discuss the specifics of your job—talking about regulations as a checklist rather than principle is a warning sign. A good electrician will ask you questions about the property, its age, and existing installations. They should explain why certain approaches are needed, not just do the cheapest option.
References matter, especially local ones (local networks are tight, and bad electricians get found out). A reputable electrician can usually offer two or three recent references without hesitation. If they seem evasive, that's telling.
Clarify whether quotes are fixed-price or time-based, what counts as unforeseen problems, and how you'll be kept informed of delays. Hidden costs after work starts is a common source of complaints. Clear communication upfront prevents this.
If you're using a directory like Electricians Around, check reviews carefully:
You'll likely get multiple quotes. Don't just pick the cheapest. Compare like-for-like:
The middle quote is often the safest bet. Too cheap usually means corners cut; too expensive might reflect overhead rather than quality.
