Domestic vs Commercial Electrician: Differences & Pay

When people think of an electrician, they often picture someone rewiring a house or fitting a new socket. But the electrical trade covers an enormous range of work, from single domestic light fittings to multi-million pound commercial installations. The two broadest categories are domestic and commercial electrical work, and they differ significantly in terms of day-to-day experience, qualifications, earning potential, and career progression.

Understanding these differences early in your career helps you make informed decisions about which direction to take. Many electricians work in both sectors at different points, and having experience across both makes you more versatile and employable.

Domestic work covers all electrical installations in residential properties — houses, flats, bungalows, and HMOs. This includes new installations, alterations, additions, rewires, consumer unit upgrades, and periodic inspection and testing.

What the Work Involves

• ✓Rewiring houses and flats (first fix and second fix)
• ✓Consumer unit replacements and upgrades
• ✓Adding sockets, lighting circuits, and outdoor supplies
• ✓Kitchen and bathroom electrical work
• ✓EV charger installations
• ✓Electrical Installation Condition Reports (EICRs)
• ✓Fire alarm and smoke detector installation
• ✓Fault finding and repair

Working Environment

Domestic electricians typically work alone or in pairs. The work takes you into people's homes, which means you need good communication skills and the ability to work tidily and respectfully in occupied properties. No two days are the same — you might be chasing walls in a Victorian terraced house in the morning and fitting a modern consumer unit in a new-build in the afternoon.

Part P of the Building Regulations applies to domestic electrical work in England and Wales. This means notifiable work (such as new circuits, consumer unit replacements, and bathroom installations) must be either certified through a competent person scheme or notified to building control.

Typical Earnings

Commercial electrical work covers non-residential properties — offices, shops, restaurants, hotels, schools, hospitals, warehouses, and construction sites. The scale is typically larger, the systems more complex, and the work is almost always done as part of a team.

What the Work Involves

• ✓Three-phase power distribution systems
• ✓Large-scale lighting installations (including emergency lighting)
• ✓Data cabling and structured wiring
• ✓Fire alarm systems and emergency voice communication
• ✓Containment systems (cable tray, basket, ladder, trunking)
• ✓Building management system interfaces
• ✓High-level work using scaffolding, cherry pickers, and access platforms
• ✓New-build construction and fit-out projects

Working Environment

Commercial electricians work as part of larger teams, often on construction sites with multiple trades working simultaneously. The work is more structured and project-managed, with daily briefings, method statements, and risk assessments. You will typically work under a supervisor or foreman and follow detailed electrical drawings and specifications.

Most commercial sites require an ECS card for access. Without one, you will be turned away at the gate. Many sites also require additional safety inductions, CSCS qualifications, and specific PPE including hard hats, steel-toe boots, and hi-vis clothing at all times.

Typical Earnings

• ✓Employed (JIB rates): 35,000 to 42,000 pounds per year
• ✓Employed with overtime and allowances: 40,000 to 50,000 pounds
• ✓Self-employed day rate: 250 to 400 pounds per day
• ✓Specialist commercial (data centres, hospitals): 350 to 500 pounds per day

Industrial electrical work is a step beyond commercial and involves factories, manufacturing plants, power stations, water treatment facilities, and other heavy infrastructure. This is the most specialised sector and commands the highest rates.

Key Differences from Commercial

• ✓High-voltage systems (above 1,000V) requiring additional qualifications
• ✓Motor control centres and programmable logic controllers (PLCs)
• ✓Maintenance contracts with shift patterns (including nights and weekends)
• ✓Hazardous area installations (ATEX zones in refineries and chemical plants)
• ✓Heavier cable and containment work
• ✓More emphasis on fault-finding and preventive maintenance

Industrial electricians often earn premium rates due to the specialist nature of the work and the shift patterns involved. Day rates of 350 to 500 pounds or more are common, with some high-voltage or offshore roles commanding even higher rates. See our guide to the highest-paying electrical specialisms for more detail.

The following comparison highlights the key differences between domestic and commercial electrical work to help you decide which path suits your personality, lifestyle, and career goals.

Working Style

• ✓Domestic: work alone or in pairs, direct customer contact, varied locations daily
• ✓Commercial: team-based, project-managed, same site for weeks or months

Flexibility

• ✓Domestic: high flexibility if self-employed, choose your own hours and jobs
• ✓Commercial: more structured hours, typically 7:30 to 16:30, less flexibility

Career Progression

• ✓Domestic: sole trader, small business owner, specialism in EV or solar
• ✓Commercial: supervisor, foreman, project manager, contracts manager, director

Qualifications Required

• ✓Domestic: core diplomas + 18th Edition + 2391 + competent person scheme
• ✓Commercial: core diplomas + 18th Edition + 2391 + NVQ + ECS Gold Card

The best choice depends on your personality, lifestyle preferences, and long-term career goals. There is no wrong answer — both paths offer excellent earning potential and job security.

Domestic Might Suit You If:

• ✓You prefer working independently and making your own decisions
• ✓You enjoy variety and seeing different properties every day
• ✓You want the flexibility of self-employment
• ✓You are a strong communicator who enjoys working with homeowners
• ✓You want to build your own business over time

Commercial Might Suit You If:

• ✓You enjoy working as part of a team
• ✓You prefer the stability of employed work with regular hours
• ✓You are interested in larger, more complex electrical systems
• ✓You want a clear management career progression path
• ✓You prefer not to deal directly with customers or marketing

Many electricians combine both types of work at different stages of their career. Starting with employed commercial work to build skills and experience, then transitioning to self-employed domestic work for better earnings and flexibility is a very common and effective career path.
