Is My Non-Compete Clause Enforceable? UK Law Explained
Non-compete clauses are common in UK employment contracts — but many are unenforceable. Here's how to tell whether yours would hold up in court, and what you can do about it.
If your employer is sold, merged, or outsources your role, TUPE regulations protect your job, pay, and terms. Here's what transfers, what can't be changed, and what to do if your employer tries to cut your rights.
When a business is sold, merged with another company, or outsources a service, employees often fear for their jobs. TUPE — the Transfer of Undertakings (Protection of Employment) Regulations 2006 — exists to protect you. It is one of the most important pieces of employment law in the UK, and one of the least understood.
In short: TUPE transfers your employment from the old employer (the transferor) to the new employer (the transferee) automatically, on the same terms and conditions, as if you had always worked for the new employer.
This means:
TUPE is one of the few areas of UK employment law where protection is not limited to employees with two years' service — protection from automatically unfair TUPE-related dismissal applies from day one.
TUPE applies in two main scenarios:
When a business or part of a business is sold or transferred to a new owner as a "going concern." This includes:
A share sale — where the company itself is sold and the employer entity remains the same — does not trigger TUPE, because there is no change in employer.
Where a service is:
For TUPE to apply to a service provision change, the service must be a discrete activity that will essentially continue, and there must be an organised grouping of employees whose principal purpose is carrying out that activity.
All contractual terms and conditions transfer, including:
What does not transfer:
This is where employees most often encounter problems. The new employer may want to harmonise terms — bringing all employees onto the same contracts. TUPE significantly restricts this.
Under TUPE, changes to your terms and conditions are void if the sole or principal reason is the transfer itself. You can agree to change your contract post-transfer, but if the reason for the change is the TUPE transfer, that agreement is unenforceable.
There is one exception: changes can be made where the employer can show an economic, technical, or organisational (ETO) reason entailing changes in the workforce — essentially, a genuine operational restructuring beyond simply wanting everyone on the same contract.
In practice:
Dismissal connected to the TUPE transfer is automatically unfair, regardless of your length of service. This applies where the transfer is the sole or principal reason for dismissal.
The exception is where the dismissal is for an ETO reason entailing changes in the workforce — for example, a genuine redundancy driven by the new employer's operational needs, following a proper consultation process.
If you are dismissed in connection with a TUPE transfer:
Both the old and new employers have obligations to inform and consult affected employees (or their representatives) before the transfer takes place. Employers must provide:
This information must be provided long enough before the transfer for consultation to be meaningful. There is no fixed statutory minimum, but courts have taken a dim view of last-minute notifications.
If the employer fails to properly inform and consult, compensation of up to 13 weeks' gross pay per affected employee can be awarded at tribunal.
If your new employer:
You should:
Suppose you work in the IT department of a bank that outsources its IT function to a third-party provider. You transfer to the new provider under TUPE. Six months later, the provider wants to put all IT staff on the same contract and reduce your holiday entitlement from 30 to 25 days.
This is a TUPE-connected change. Unless the provider can demonstrate a genuine ETO reason — not simply harmonisation — any agreed change is void and you are entitled to continue receiving 30 days' holiday. If you raise a grievance and the employer ignores it, you can bring a claim at tribunal for unlawful deduction from wages or breach of contract.
