Starting an Electrician Business in the UK: A Complete Setup Guide

Thinking about becoming your own boss and starting an electrician business in the UK?

Running your own electrical business can be rewarding and profitable — but only if you get the foundations right. Beyond technical skills, you’ll need to understand qualifications, legal requirements, registrations, and insurance to stay compliant and protect yourself.

This guide explains how to set up an electrician business in the UK, step by step, in plain English.

1. Get Qualified & Experienced

Before you start trading, you must be fully qualified and competent. Electrical work is highly regulated, and there’s no shortcut here.

Essential Qualifications

Most UK electricians hold:

  • City & Guilds Level 2 & 3 Diploma in Electrical Installation

  • NVQ Level 3 in Electrotechnical Systems

  • 18th Edition Wiring Regulations (BS 7671) — this must be kept up to date

If you plan to carry out inspections or issue EICRs, you’ll also need:

  • Inspection & Testing qualifications (e.g. City & Guilds 2391)

Experience Matters

While not legally required, most successful self-employed electricians spend several years working for an established firm first. This helps you build confidence, technical ability, and real-world problem-solving skills before going solo.

2. Choose Your Business Structure

You’ll need to decide how to legally operate your business.

Sole Trader

  • Quick and simple to set up

  • You’re personally responsible for debts

  • Register for Self Assessment with HMRC

This is the most common starting point for electricians.

Limited Company

  • Separate legal entity

  • Offers personal liability protection

  • More admin (Companies House + Corporation Tax)

  • Often more tax-efficient as income grows

It's highly recommended to consult an accountant to determine the best structure for your individual circumstances.

3. Register with HMRC and Stay Compliant

Electrical businesses are heavily regulated for safety reasons.

HMRC Registration

  • Sole traders: Register for Self Assessment

  • Limited companies: Register with Companies House, then HMRC

  • The Electricity at Work Regulations 1989: These regulations impose duties on employers and self-employed individuals to ensure the safety of electrical systems and equipment in the workplace. This includes regular inspection, testing, and maintenance.

  • IET Wiring Regulations (BS 7671): As mentioned, all your work must adhere to the latest edition of these national safety standards for electrical installations.

  • Health and Safety: You have a legal responsibility to ensure your own safety, the safety of your clients, and anyone else who might be affected by your work. This includes conducting risk assessments and using appropriate PPE.

Competent Person Scheme (CPS)

If you work in domestic properties, CPS membership is essential.

Approved schemes include:

  • NICEIC

  • NAPIT

  • ELECSA

  • STROMA

Being registered allows you to self-certify your work under Part P of the Building Regulations, saving your customers time and money — and increasing trust.

Key Regulations You Must Follow

  • IET Wiring Regulations (BS 7671)

  • Electricity at Work Regulations 1989

  • Health & Safety at Work requirements, including risk assessments and PPE

Non-compliance can lead to fines, invalid insurance, or worse.

4. Essential Insurance for Electricians

Insurance isn’t optional in electrical work — it’s protection for you, your clients, and your livelihood.

Must-Have Cover

  • Public Liability Insurance
    Covers injury or property damage caused by your work. Most electricians carry £2m–£5m cover.

  • Professional Indemnity Insurance
    Essential if you provide advice, designs, or recommendations.

  • Employers’ Liability Insurance
    A legal requirement if you employ anyone — even part-time or apprentices.

Strongly Recommended

  • Tools & Equipment Insurance

  • Commercial Van Insurance

  • Personal Accident Insurance

  • Legal Expenses Insurance

  • Product Liability Insurance (often included with public liability)

Once the legal side is covered, it’s time to build a business — not just a job.

Key Setup Steps

  • Create a simple business plan

  • Buy calibrated testing equipment and quality tools

  • Open a business bank account

  • Set up basic bookkeeping

  • Build a professional website

  • Register with local directories

  • Start collecting reviews early

Systems matter. Getting this right early saves stress later.
