Finding a reliable electrician in London can feel like a challenge. Whether you’re facing a flickering light, planning a full rewire, or need an urgent repair, you want someone who is skilled, trustworthy, and safe. Making the wrong choice can lead to unsafe wiring, hidden costs, and endless stress.
So, how do you sort the best from the rest? Before you hire any electrician in London, make sure they pass these five essential checks.

1. Are They NAPIT Registered?
This is the most important check of all. The NAPIT (National Association of Professional Inspectors and Testers) is a leading UK government-approved scheme for tradespeople in the building sector. A NAPIT-registered electrician is regularly assessed to ensure their work meets the highest safety and technical standards.
Hiring a NAPIT-registered electrician means:
- Safety: Their work complies with UK safety standards (BS 7671).
- Competence: They are competent to carry out the work you need.
- Compliance: They can self-certify their work and provide you with the necessary legal certificates.
Never hire an electrician who isn’t part of a recognized scheme like NAPIT.
2. Check Their Reviews and Reputation
In today’s digital world, it’s easy to see what past customers think. A truly professional electrician will have a strong track record of positive feedback. Look for reviews on independent platforms like:
- Google Reviews
- Trustpilot
- Checkatrade
Look for comments on their professionalism, punctuality, communication, and the quality of their work. A history of happy customers is one of the strongest indicators you’ve found one of the best electricians in London.
3. Do They Offer Transparent Pricing?
No one likes a surprise bill. A reputable electrician will be upfront about their costs. While some minor diagnostic jobs may be billed by the hour, they should always provide a clear, written quote for any significant work before they begin.
A transparent quote should detail the cost of labour and materials. Be wary of vague estimates or anyone who is unwilling to put their pricing in writing.
4. What is Their Range of Services?
A well-established electrical company should be able to handle a wide variety of jobs, not just simple fixes. This demonstrates experience and a deep understanding of all things electrical. Look for a company that confidently offers services such as:
- Electrical Installation Condition Reports (EICR) for landlords and homeowners
- Full and partial rewires
- Fuse box / consumer unit upgrades
- EV charger installations
- Emergency call-outs
- Lighting and socket installation
5. Are They Insured and Do They Guarantee Their Work?
Accidents are rare, but they can happen. A professional electrician must have public liability insurance to protect you and your property in case of any damage.
Furthermore, the best electricians will stand by the quality of their work. Ask if they offer a guarantee on their workmanship. This shows they are confident in their skills and committed to providing a lasting, high-quality solution.
