UK Employer Rules · 2026
Can my employer cut my pay without my agreement?
Legal basis
Employment Rights Act 1996 — section on legislation.gov.uk">Employment Rights Act 1996 s.13 (unlawful deductions from wages); contract law principles; National Minimum Wage Act 1998 (cannot reduce below NMW under any circumstance).
When they CAN do it
Your employer CAN reduce pay if: (1) you give written consent; (2) the contract specifically allows it (rare and very narrowly interpreted); (3) you've agreed to a temporary reduction during financial distress (e.g., the COVID 'agreed pay cut' arrangements many employees signed in 2020); (4) the reduction is to a discretionary bonus that the contract makes clear is genuinely discretionary, not contractual; (5) it's part of a formal redundancy or restructuring consultation and you accept the new terms.
When they CANNOT do it
Your employer CANNOT: unilaterally cut your basic salary; reduce contractual bonuses or commission rates; remove allowances written into your contract (London weighting, on-call, shift premium); reduce employer pension contributions below the contractual rate; cut pay below the National Minimum Wage in any circumstance; deduct pay for 'underperformance' without express contractual right.
What you should do
1) Do not agree verbally or in writing — ask for the proposal in writing. 2) Object in writing immediately. 3) Continue working at your contracted rate. 4) Raise a formal grievance. 5) File an unlawful deductions from wages claim with ACAS (free conciliation, then tribunal if needed) — no minimum service requirement, 3-month time limit from each deduction. 6) If pattern continues, consider constructive dismissal (need 2 years' service). 7) Keep all payslips as evidence.
Worked example
Priya's manager called her in and said her commission rate was being cut from 10% to 6% due to 'a new company-wide policy'. The reduction would cost her £450/month. She emailed HR the same day saying she did not consent. HR initially tried to push it through, but when she escalated to a formal grievance with reference to s.13 ERA 1996, they restored her commission rate and apologised. She kept records throughout.
Red flags — when to escalate
🚨 Pay cut announced verbally with no follow-up document. 🚨 Pay cut described as 'just for now' with no end date. 🚨 'Sign this new contract or you'll be replaced' threats (fire-and-rehire — see 2024 statutory code). 🚨 Reductions to less than National Minimum Wage. 🚨 Deductions for tools, uniform, training without written agreement.
Recruiter pro tip
Unlawful deductions cases are some of the easiest tribunal claims to win because the question is binary: did you consent in writing? If no, you win. Always insist on written consent if your employer wants to vary pay — and never sign anything in the moment. Take 24 hours minimum, get advice (ACAS free helpline 0300 123 1100), and respond in writing.
