UK Employer Rules · 2026
Can my employer cancel my approved annual leave?
Legal basis
Working Time Regulations 1998 reg. 15 (notice to cancel leave); Equality Act 2010; common law breach of contract.
When they CAN do it
Your employer CAN cancel approved leave if: (1) they give written notice at least as long as the leave being cancelled; (2) there's a legitimate business reason (e.g., another employee unavailability, peak demand); (3) the contract or staff handbook permits it; (4) they cover any reasonable non-refundable costs you've incurred. Some contracts also have specific cancellation procedures.
When they CANNOT do it
Your employer CANNOT: cancel once you've started your leave; cancel with less than the required notice (length of leave to be cancelled); cancel for discriminatory reasons (e.g., to avoid you taking it during pregnancy); cancel and not reimburse losses; cancel and refuse to roll the leave forward; force you to lose statutory leave (5.6 weeks/year minimum) by cancelling repeatedly.
What you should do
1) Get the cancellation in writing with the reason. 2) Check if notice given is at least as long as the leave being cancelled. 3) Document any non-refundable costs (flights, hotels, deposits). 4) Email back asking for reimbursement of unrecoverable costs and confirmation the leave will be re-booked. 5) If pattern of cancellations, raise a grievance — repeated cancellations preventing you from taking statutory leave is a breach. 6) Tribunal claim for unpaid leave (Employment Rights Act s.13) within 3 months less 1 day.
Worked example
Rachel had booked 2 weeks off for a family wedding in Italy 4 months in advance, all approved. 5 days before her flight, her manager emailed cancelling because of 'staffing issues'. She'd paid £1,800 for non-refundable flights and hotel. She replied citing WTR reg. 15 notice requirements (would need 2 weeks' notice for 2 weeks' leave) and demanded the leave stand. Manager backed down within 24 hours after HR review. Saved the £1,800 plus the family event.
Red flags — when to escalate
🚨 Cancellation with less than the WTR notice. 🚨 No alternative date offered. 🚨 No reimbursement offered for sunk costs. 🚨 Pattern of cancellations to specific employees. 🚨 Cancellation after a grievance, sickness absence, or pregnancy announcement.
Recruiter pro tip
Most employees don't know about WTR reg. 15. The notice requirement is a hard floor — even contracts with shorter cancellation provisions cannot override it for statutory holiday. Always reply in writing citing reg. 15 with the calculation: 'You require [X] days' notice to cancel [X] days' leave; this notice is [Y] days; therefore the cancellation is invalid'. 9 times out of 10, the employer backs down.
