Are your courier drivers really self-employed? Status and substitution explained
By the Qinetic team · Updated October 2026
Most same-day courier firms run on owner drivers who invoice as self-employed. That model works, and it's lawful, but it only holds if the way you actually work with drivers matches what the contract says. Get it wrong and a driver can claim worker rights, such as holiday pay and the minimum wage, backdated. Here's what decides it.
Three statuses, not two
UK employment law has three main categories. Employees have the full set of employment rights. Workers sit in the middle: they don't get everything an employee gets, but they are entitled to things like the National Minimum Wage and paid holiday. Self-employed people running their own business get neither.
Most courier disputes are about the middle category. Few owner drivers argue they're employees. Many argue they're workers. And status for tax is a separate question again, so a driver can be self-employed for HMRC and still be found to be a worker by a tribunal.
What tribunals look at
The label in the contract isn't decisive. Courts look at the reality of the relationship. The questions that come up again and again are:
- Personal service: does the driver have to do the work themselves, or can they genuinely send someone else?
- Control: who decides the rates, the routes, the hours, the uniform and what happens if a job is turned down?
- Obligation: is the driver expected to accept work, and are you expected to offer it?
- Business risk: does the driver supply and pay for their own van, insurance and fuel, and can they make or lose money by how they work?
- Other customers: are they free to work for other firms, including your competitors?
In Uber v Aslam (2021) the Supreme Court found drivers were workers because Uber controlled the fares, the terms and how they were rated. Courier cases have gone the same way where the firm held tight control, but each case turns on its own facts.
Why substitution matters so much
Worker status needs an obligation to do the work personally. A genuine right to send a substitute cuts straight through that. In the Deliveroo case (2023), the Supreme Court found riders were not in an employment relationship mainly because their right to use a substitute was "virtually unfettered": they could send anyone, before or after accepting a job, without Deliveroo policing it or penalising them for it.
The word that matters is genuine. A substitution clause that needs your approval, only allows other drivers already on your books, or is never used in practice and would be frowned on if it were, carries much less weight. In Pimlico Plumbers v Smith (2018), a heavily limited right to substitute didn't stop the plumber being found a worker.
The 2026 complication
From 1 October 2026, Right to Work checks extend to individual subcontractors and their substitutes. Where a contract allows substitution, you now need to check each substitute yourself before they start, and be able to show the person doing the work is the person you checked.
That sits awkwardly next to the Deliveroo reasoning, where not policing substitutes helped show the right was genuine. Checking substitutes is a legal requirement in its own right, and it isn't the same as controlling who the driver chooses. But how the two will be weighed against each other hasn't been tested yet. If your status position relies on a substitution clause, have your contracts reviewed with both in mind.
A practical checklist
- Read your contract against reality. If it says drivers can refuse work but you drop people who do, the reality wins.
- Make substitution workable. Let drivers send a substitute, and have a quick, standard way to onboard and check that person.
- Avoid unnecessary control. Be clear about what the customer requires, but don't add rules that only an employer would set.
- Let drivers carry business risk. Their own van, insurance and costs, and freedom to work for others.
- Self-bill properly. Clear rates and itemised invoices show a business-to-business relationship. See our self-billing guide.
- Keep records. If a claim comes, you'll need to show how the relationship worked in practice, not just what the contract said.
How Qinetic helps
Qinetic can't decide anyone's status; only the facts and, ultimately, a tribunal can. What it does is keep the records that show how you work with each driver: the contract they signed, the documents and Right to Work checks for them and any substitute, their availability, and self-bill invoices built from agreed rates. When someone asks how the relationship works in practice, you have the answer on one record.
Common questions
Does IR35 apply to owner drivers?
IR35 applies when someone works through their own limited company or another intermediary. Most owner drivers are sole traders, where the question is their employment status for tax and employment law, not IR35. If drivers do work through their own companies, take advice.
Does self-billing make a driver self-employed?
No. Self-billing is an invoicing arrangement. It's consistent with self-employment, but it doesn't decide status on its own.
Who decides employment status?
Ultimately employment tribunals and courts, based on the facts. Acas can give free guidance, and an employment lawyer can review your contracts and working practices.
