How to start an electrical business

The introduction of smart technology and continued reliance on digital infrastructure, alongside the UK government’s promise to build 300,000 (external link) new homes per year, suggests that the electrical contracting sector could be thriving. 

Recent surveys (external link) suggest that there is a shortage of skilled electricians, and electrical vacancies are some of the hardest to fill skilled trade roles. That skills gap can indicate that there are opportunities for new businesses to establish themselves, particularly in areas with high demand or emerging specialisations like sustainable energy installations.

Self-employed electricians' work can vary significantly depending on specialisation and market focus. Day-to-day tasks might include checking electrical system safety, installing control panels, repairing machine components, fitting sockets and switches, and installing infrastructure such as streetlights. 

Some self-employed electricians may focus on residential rewiring while others specialise in commercial projects, industrial maintenance, or emerging areas like electric vehicle charging installations.

Earning potential may vary based on location, specialisation, and business efficiency. According to the Office for National Statistics (ONS) (external link), the average salary for employed electricians in the UK is around £32,315, with starter salaries typically around £26,000.¹ (external link) Self-employed electricians might expect to earn more. Day rates can range from £180 to £350, while hourly rates might range from £25 to £60.² (external link)

Becoming a qualified electrician typically requires completing recognised industry qualifications through various routes, including apprenticeships, adult learning programs, or career change pathways. Essential qualifications generally include a Level 3 Diploma in subjects such as Installing Electrotechnical Systems and Equipment, Electrotechnical Services, or Electrical Installations. Additional requirements made include the BS7671 certification and awards in Initial and Periodic Inspection and Testing.³ (external link) 

You can find current qualification information via the relevant trade bodies: Electrical Contractors Association (ECA) (external link), SELECT (external link) for Scotland, or the Electrical Training Trust (ETT) (external link) for Northern Ireland.

Practical industry experience can prove invaluable when starting a business. Working for established companies may provide insights into operations, business practices, and client relationship management. This experience might help build networks of contacts, suppliers, and potential clients. 

Some electricians may choose initial self-employed contracting as a stepping stone, providing opportunities to develop client bases while maintaining independence and flexibility.

Establishing a successful electrical business can require careful planning and awareness of various regulatory, financial, and operational requirements. 

1. Write a business plan 

A comprehensive business plan can serve as your roadmap, helping clarify goals whilst potentially supporting funding applications. Your electrical business plan could include: 

• Business and service descriptions.
• Local market and competitor analysis.
• Marketing strategies, operational plans.
• Financial forecasts, including startup costs and revenue projections. 

Regular business reviews can help you track progress and adapt as conditions change and you learn what works. 

2. Sole trader vs limited company 

You will need to decide whether you want to operate as a sole trader or register as a limited company. Many electricians start as sole traders, establishing a limited company as their business grows. Here are some of the main differences between each business setup:

3. Get the right insurance cover 

Ensuring you are appropriately covered can help you protect your business and meet legal requirements: 

• Public liability insurance – can protect you against claims if a member of the public injures themselves as a result of your work or at your workplace, or if you accidentally damage someone’s property.
• Professional indemnity insurance – can protect you if a customer claims they have suffered a financial loss due to work you completed or advice you gave.
• Employers’ liability insurance – is typically a legal requirement if you hire staff, covering you if an employee gets injured or falls ill as a result of their work for you.
• Specialist tool insurance – cover the equipment you use for your work. 

4. Register with a competent person scheme

Registration with schemes like NICEIC (external link) or NAPIT (external link) allows qualified electricians to self-certify work, complying with building regulations. Accreditation can help build client confidence by demonstrating reputability, while potentially providing you with access to technical support, training updates, and marketing benefits. 

5. Source reliable suppliers 

Establishing relationships with dependable electrical wholesalers can help electricians deliver consistent, competitively priced services. Quality suppliers might offer reliable availability, direct delivery, and flexible payment terms such as 30-day credit that can help manage cash flow. 

6. Invest in tools, equipment and a branded vehicle

Investing in quality tools and equipment can be costly, but it is often essential when setting up an electrical business: 

• Basic tools: screwdrivers, pliers, wire strippers, and multimeters for everyday work. Testing equipment: insulation resistance testers and RCD testers for safety verification.
• Power tools: drills, angle grinders, and cable pullers for efficient installations.
• Safety equipment: hard hats, safety boots, high-visibility clothing, and voltage detectors.
• Specialist tools: thermal imaging cameras or fault location equipment, depending on specialisation. 

Many electricians use a van as both essential transport and mobile advertising. Professional vehicle branding with company logos and contact details can provide ongoing marketing value, though maintaining a professional appearance and considerate driving may be important for business reputation.
