What's changing: Employment Rights Act 2025

The Employment Rights Act 2025 introduces a right to guaranteed hours for zero hours and low-hours contract workers. The changes are expected to come into force in 2027, subject to secondary legislation.

The reference period rule

Workers who have worked a regular pattern over a 12-week reference period can request a guaranteed hours contract reflecting that pattern. Employers cannot unreasonably refuse.

Short-notice cancellation pay

If an employer cancels a shift at short notice after the worker has arrived or is on the way, the worker will be entitled to compensation. The notice threshold is to be set by regulation.

Reasonable notice obligations

Employers will need to give reasonable notice of shifts. The definition of "reasonable" will be set in secondary legislation, but businesses should expect it to cover at least 48-72 hours.

Who this affects

The rules apply to workers on zero hours and low-hours contracts. Agency workers are covered by separate provisions. Casual workers with genuinely no regular pattern may still be outside the scope.
