Electricians are one of the easiest trades to misread. A self-employed contractor quoting £250 a day can appear to out-earn an employed electrician. Then the van, fuel, insurance, tools, holiday time, gaps between jobs, and tax arrive, and the number shrinks fast.
The cleanest comparison is not “salary” versus “day rate.” It is an employed package versus business turnover. These are not the same. Once you separate them, the gap narrows, and the job market looks less theatrical.
The employed pay picture
The National Careers Service puts employed electricians on roughly £26,000 to £45,000 a year for a 37 to 45 hour week. This broad range exists for a reason. A newly qualified installation electrician will sit near the lower end. An industrial or maintenance electrician with experience, fault-finding ability, and responsibility for keeping production moving can climb much higher.
Think about employed pay in terms of routes, not just a single headline number.
An installation electrician on building sites or domestic projects usually starts with bread-and-butter work: wiring, testing, and fixing faults. Pay can be modest at first, but the route is steady and the hours are clearer.
An industrial or maintenance electrician is often paid more because the work is more technical and the cost of getting it wrong is higher. If a factory line stops, somebody notices immediately. This pressure shows up in wages, and in some cases can push earnings towards the upper end of the National Careers Service range, or beyond it in London and the South East.
Then there are the extras. Call-outs, overtime, testing qualifications, renewables work, and supervisory responsibility can all push employed earnings up. A site electrician who can test, sign off, and supervise will usually sit in a stronger position than someone doing basic install work alone.
The other half of the employed deal matters just as much as the wage. Paid annual leave is part of the package. ACAS puts the legal minimum at 5.6 weeks, which is 28 days for a full-time worker including bank holidays. There is also employer pension support. Under auto-enrolment, the minimum employer contribution is 3% of qualifying earnings, with 5% from the employee. This does not sound dramatic until you compare it with the self-employed route, where you have to find the pension money yourself.
A realistic employed example is a package worth £38,000 a year. That might include a salary, paid leave, and employer pension contributions. It is not the highest number on the board, but it is money you can actually compare with another job because it is not hiding business costs inside the headline.
Why self-employed rates fool people
Self-employed electricians often quote a day rate, not a salary. This distinction carries a lot of weight.
If a contractor says they charge £250 a day, that is turnover. It is money coming into the business before the business pays for itself. A customer pays for labour, but they also pay for the van, the fuel, the tools, the insurance, the certification, the admin, and the empty days when no one books the job.
A customer rate should never be treated as the electrician’s personal hourly wage. That is how people convince themselves a self-employed electrician “earns” more than someone employed, when in reality the business is just collecting revenue and then paying a long list of bills.
A self-employed electrician funds a small business every time they leave the house.
A real £250 a day example
Take a self-employed domestic contractor charging £250 a day and working 210 chargeable days in a year. That produces annual turnover of £52,500.
Now pull out the costs.
A van on finance or lease might cost £300 to £400 a month. Fuel can run another £200 to £300 a month, especially if the work is spread across London, Manchester, Birmingham, or wider suburban patches where the mileage piles up. Servicing, tyres, road tax, and repairs continue whether the diary is full or not.
Insurance eats into the same pot. Public liability cover is not optional if you want to look credible and stay protected. Tool insurance and, depending on the work, professional indemnity cover add more overhead. Then there is registration and certification. Approval schemes such as NICEIC or NAPIT, Part P-related admin, and annual renewals are not free.
Tools need replacing. Test equipment needs calibration. Consumables vanish faster than people expect. A set of proper electrical tools is not a one-off purchase that lasts forever.
The hidden cost most people ignore is time. Quoting is unpaid. Picking up materials is unpaid. Chasing invoices is unpaid. Admin is unpaid. Holidays are unpaid. When an employed electrician is off work, they still get paid. The self-employed electrician has to bank enough during the busy months to survive the quiet ones.
Set the business costs at a realistic level, and £52,500 starts shrinking quickly. Overheads can easily consume £8,000 to £12,000 before tax and pension are even considered. That leaves something more like low-to-mid £40,000s before personal tax, and that is before the contractor has paid themselves for future downtime.
Pension provision also matters. An employed electrician gets an employer contribution automatically. The self-employed electrician has to decide whether to do the grown-up thing and pay into a pension, or spend everything now and deal with the consequences later. If they put money aside sensibly, take-home income falls again.
Then tax arrives. Self-employed income is taxed on profit, not turnover. Even so, once income tax and National Insurance are accounted for, the nice round £52,500 figure looks far less generous than people imagine. After business costs, pension saving, and tax, the personal take-home may end up uncomfortably close to a decent employed package.
The comparison that actually matters
A useful comparison: the employed electrician on £38,000 receives a package with paid leave and employer pension contributions. The self-employed contractor has to build those benefits out of their own gross income.
That changes the maths.
The employed worker gets certainty. The self-employed worker gets control, but also risk. If the diary has a bad month, no employer tops it up. If a van breaks down, the business pays. If a customer delays payment, the contractor carries the cash-flow pain. If two weeks vanish to illness, the income disappears with them.
The self-employed route can still win, but only if the business is strong, the rates are high enough, and the electrician stays busy. A domestic contractor with good local demand, solid reviews, and repeat customers can do well. Add commercial work, testing, renewables, or emergency call-outs, and the income mix improves again.
The claim that self-employed electricians always make much more than employed ones is sloppy. A fair comparison has to subtract the costs that an employee never sees.
Qualifications shape the path to better pay
The route into electrical work matters because pay follows competence, not wishful thinking.
Apprenticeships remain the clearest entry point for many people. They give a wage, structured training, and a route to recognised qualifications. That is how a lot of electricians get from labourer-level money to proper trade pay.
Once qualified, recognised electrical certifications open the next door. They make it easier to move into testing, inspection, domestic certification, industrial maintenance, or renewables. Those are the areas where pay tends to improve because the work is harder to outsource and the consequences of mistakes are expensive.
A newly qualified electrician is rarely on top money straight away. The bigger jump often comes after a few years, once they can work without hand-holding and take responsibility for more complex jobs. A supervisor, tester, or industrial maintenance electrician usually earns more than someone who only does straightforward installation work.
That progression is why apprenticeships still matter. They are not glamorous, but they are the shortest route to a proper wage in a trade where the difference between basic labour and specialist knowledge can be several thousand pounds a year.
The blunt answer
If you want absolute control and are willing to carry the overheads, self-employment can pay well. If you want cleaner cash flow, paid holidays, employer pension contributions, and less time spent acting as your own accounts department, employed work is often the better deal than the internet’s loose talk about “day rates” suggests.
The real comparison is not between £250 a day and £38,000 a year. It is between gross business turnover and actual personal take-home. Once you include van costs, fuel, tools, insurance, certification, unpaid admin, holidays, pension, and tax, the gap gets much smaller than people like to pretend.
