Revenue Benchmarks by Business Size
Electrician business revenue varies enormously based on size, specialisation, geography, and business model. Here are realistic benchmarks for 2026:
| Business Type | Annual Revenue Range | Typical Net Margin | Owner Take-Home |
|---|---|---|---|
| Sole trader, domestic focus | £60,000–£120,000 | 50–65%* | £30,000–£65,000 |
| Sole trader, mixed domestic/commercial | £80,000–£150,000 | 45–60%* | £36,000–£75,000 |
| Small team (2–4 electricians) | £200,000–£450,000 | 15–25% | £40,000–£90,000 |
| Mid-size (5–10 electricians) | £500,000–£1,000,000 | 12–20% | £60,000–£150,000 |
| Larger business (10+ electricians) | £1m+ | 10–18% | £100,000–£200,000+ |
*Sole trader net margin is higher because there are fewer overhead layers — no employer's NI, no staff management costs
These figures are realistic midpoints. Electricians in London and the South East are typically at the upper end of these ranges; those in Northern England and Wales at the lower end.
What Determines an Electrician Business's Profitability
Revenue is vanity, profit is sanity. Two electrical businesses with identical revenue can have very different profitability based on five key factors:
1. Pricing
The most directly controllable lever. An electrician charging £80/hour earns 45% more than one charging £55/hour for the same work. Many electrical businesses are chronically underpriced because owners never calculated their minimum viable rate. A 15% price increase without changing anything else directly adds 15% to gross revenue — disproportionately more to net profit because fixed costs stay the same.
2. Job mix
Not all jobs are equally profitable. EV charger installations (typically £400–£800, 2–4 hours) generate better effective hourly rates than fault-finding calls (£65/hour for unpredictable duration). Businesses that skew their job mix towards higher-value, faster-completion work earn significantly more per day. Tracking profitability by job type reveals where your time is most valuable.
3. Overhead control
Van finance, insurance, tools, software, and marketing add up to £15,000–£25,000/year for a well-equipped sole trader. Growing businesses add employee costs, premises costs, and management overhead. Every pound of unnecessary overhead is a pound of profit lost. Review overhead costs annually and challenge each line item.
4. Staff utilisation
For businesses with employees, the key metric is how many billable hours each employee generates per day. An employee generating 6 billable hours per day at £65/hour produces £390. An employee generating 4 billable hours produces £260 — the difference in profitability over a year is enormous. Poor scheduling, excessive travel, and non-billable tasks all reduce utilisation.
5. Payment efficiency
Late invoicing and slow payment have a direct cost. An invoice sent 3 days after completion instead of the same day delays cash by 3 days. At £50,000/year of receivables, each day of average delay costs roughly £140 in interest cost (at current rates). More critically, unpaid invoices that are never chased represent direct profit loss.
How Revenue Grows as You Scale
Growing an electrical business beyond sole trader adds revenue but also adds costs. Understanding the relationship between growth and profit helps you decide whether scaling is actually the right goal.
The scaling curve:
- A sole trader earning £90,000 revenue might take home £50,000 after all costs and tax
- The same business with one employee now generates £160,000 revenue but adds £35,000 in employment costs — net take-home might be £55,000–£65,000
- With three employees at £400,000 revenue and £120,000 in employment costs, management overhead, and additional expenses, take-home might be £70,000–£90,000
The first two hires often feel like working harder for marginally more money. The real financial inflection point for most electrical businesses comes at around 5–7 employees, where economies of scale and management leverage start delivering disproportionate returns.
This doesn't mean scaling isn't worth it — many electricians find managing a team more rewarding than being on tools indefinitely, and a larger business has exit value a sole trader doesn't. But going in with clear-eyed expectations about the financial trajectory is important.
Top Earner Characteristics
What distinguishes the top-earning electrical businesses from average ones? Across business types, certain characteristics consistently appear:
- Premium pricing with confidence — top earners charge above-average rates without apology, and invest in the quality signals (reviews, appearance, communication) that justify those rates
- High-value service specialisation — EV charging, solar integration, commercial fit-out, smart home — higher-complexity work commands higher margins
- Strong repeat customer base — landlords, commercial clients, and maintenance contracts provide predictable recurring revenue that reduces marketing cost and income volatility
- Excellent operational systems — job management software, structured scheduling, same-day invoicing, and systematic review collection. These businesses waste less time on admin and capture more revenue from the same work
- Geographic focus — concentrating work in a defined area reduces travel time, builds local brand recognition faster, and makes scheduling more efficient
Tax Considerations for Electrician Business Owners
Understanding your tax position is essential for knowing what you actually take home. UK electricians face several tax considerations:
Sole trader: Pay Income Tax (20% basic rate, 40% higher rate above £50,270) and Class 4 National Insurance (9% on profits between £12,570 and £50,270, 2% above). On £90,000 profit, total tax and NI is approximately £28,000–£30,000, leaving take-home of around £60,000–£62,000.
Limited company: Corporation Tax of 25% on profits above £50,000. Efficient salary/dividend split (e.g. £12,570 salary + remainder as dividends) can reduce total tax significantly vs sole trader at higher profit levels. A company generating £90,000 profit, paying a £12,570 salary and the remainder as dividends, typically results in approximately £5,000–£8,000 less total tax than the equivalent sole trader — worth incorporating for most businesses above £40,000 profit.
These are approximate figures — an accountant who specialises in trades businesses will produce a personalised analysis and ensure you're claiming all legitimate expenses (van, tools, home office, professional development, etc.).
