Unlawful Pay Deductions (UK): How to Challenge Them
If money has been deducted from your wages without clear legal basis or consent, you may be dealing with an unlawful deduction from wages claim.
The short answer
In the UK, deductions from wages are only lawful in limited circumstances, such as contractual clauses, statutory deductions, or written consent. If none apply, challenge the deduction in writing immediately.
Contents
When a deduction may be unlawful
Deductions are often unlawful if there is no contractual clause, no statutory basis, and no explicit written employee consent.
Evidence to gather
Keep payslips, contract terms, handbook extracts, and any payroll communications confirming or explaining the deduction.
Escalation options
Escalate internally first, then consider ACAS Early Conciliation if the issue is not resolved promptly.
