How to Vet an Electrician: Credentials, Insurance and Reviews Explained

Why It’s Important to Vet Your Electrician

Most people don’t spend much time thinking about who they hire to fix the wiring – they should, the risks are real. A poorly done job can lead to fire, serious injury, or worse. It doesn’t take much, one shortcut, one overlooked detail, that’s all it takes to put your home or business in danger.

Finding someone who knows what they’re doing is more than a box to tick – it’s the difference between peace of mind and a disaster waiting to happen. But with so many options, how do you know who’s reliable?

You don’t need a degree in electronics, you need to know what to ask. Pay attention to how someone talks about their work. Are they vague? Do they overpromise? Or are they straight with you? This guide helps you tell the difference.

1. Check for Proper Qualifications and Certifications

No one should be working on your electrics without proper certification – that’s non-negotiable. In the UK, NICEIC, ELECSA, and NAPIT are the names to look for, these organisations don’t hand out approval lightly.

Ask to see the paperwork, a certificate, ID, something that confirms they’re qualified and compliant. Don’t just take their word for it, if they stall or make excuses, find someone else.

While you’re at it, ask about the kind of work they do most. Experience matters, a contractor who spends most of their time in office blocks might not be the best fit for a period home. Same goes for someone who’s never handled a full rewire.

At DGEC, we keep it simple. We’re NICEIC-approved and proud of it, our electricians have tackled everything from small repairs to large installations.

2. Verify Insurance Coverage

Insurance is one of those things you hope you never need. But when something goes wrong, you’ll be glad it’s there.

Ask the electrician if they’re covered. Public liability insurance is essential, it protects your property and your safety. If they’re doing design or inspection work, ask about professional indemnity cover too.

You don’t need to read the fine print, but you should check that the policy is active. Make sure the coverage amount makes sense – ask what it includes.

DGEC never starts a job without full cover. We don’t leave room for doubt, neither should you.

3. Read Reviews and Testimonials

You can tell a lot from a review. Even more from the way a business responds to them.

Before hiring, spend five minutes looking them up; Google, Trustpilot, Checkatrade. Look past the stars, read what people are actually saying. Are they happy with the work? Was the electrician on time? Was the job left tidy? Was communication good throughout?

Patterns are important. One bad review might not mean much, but ten reviews that all mention the same issue? That’s something else.

We keep track of every review at DGEC. We listen, we respond, we improve, and we’re proud of what our clients have to say.

4. Ask About Experience and Past Projects

Every job is different, that’s not just a saying, it’s the truth.

Older houses have quirks – lofts can be awkward. New builds aren’t always straightforward either, you want someone who’s worked on similar properties.

Ask questions, what’s the most complex job they’ve done? How did they handle it? What do they do when something unexpected comes up? A good electrician will tell you, they might even enjoy it. Sharing that experience isn’t about showing off, it’s proof they’re prepared.

We see a wide range of properties at DGEC, that means we know how to adapt. No job is routine. Every one gets our full attention.

5. Get a Written Quote and Scope of Work

Never settle for a vague estimate, it’s not enough.

You need a detailed, written quote. Something you can look back at, something you understand. What’s being done? How long will it take? What does it cost? And what’s not included?

Ask about delays, what happens if the job runs over? If they find a hidden problem? These are the kinds of things that should be discussed before work begins.

We provide clear, no-nonsense quotes at DGEC. We lay it out from the start, no surprises, Just honest pricing.

6. Assess Communication and Professionalism

The first conversation says a lot. So does the second.

Was your message answered quickly? Was the person polite? Did they seem rushed or distracted?

Communication matters more than you might think. A professional who takes time to explain things upfront will likely do the same once the job starts. If someone doesn’t treat you well before being hired, don’t expect that to change later.

At DGEC, we stay in touch, from the first message to the final handover. You’ll always know where things stand.
