How we source and date every measure
The tracker is only useful if the dates are right, so here is exactly where they come from and how we decide whether a measure is in force, confirmed, or still awaiting regulations.
Primary sources
Every measure and date is taken from primary government sources, cross-checked against each other:
- The Act itself, the Employment Rights Act 2025 on legislation.gov.uk, which records Royal Assent on 18 December 2025.
- The government implementation roadmap and its revised timeline update on GOV.UK, which set the tranche dates. Where the July 2025 roadmap and the revised timeline differ, the revised timeline governs.
- Acas guidance on the Employment Rights Act 2025, which corroborates the 6 April 2026 changes, the Fair Work Agency on 7 April 2026, and the January 2027 dismissal changes.
How we classify status
Each measure carries one of three plain-text labels, never colour alone:
- In force: the commencement date has already passed as at the generation date of your report.
- Confirmed: a date has been set by commencement regulations or the government's revised timeline, but has not yet arrived.
- Awaiting regulations: the government has named a period (for example "2027") but the precise date or detail is still subject to consultation and secondary legislation. We show these as expected, never as a hard promise.
Two corrections we take seriously
Two points are easy to get wrong, and older pages elsewhere still do:
- Unfair dismissal is not a day-one right. The original Bill proposed day-one unfair dismissal with a statutory initial period of employment. That proposal was defeated in the House of Lords and abandoned. The Act reduces the qualifying period from two years to six months, from 1 January 2027.
- Fire and rehire moved. The July 2025 roadmap first indicated October 2026; the revised timeline moved the automatically-unfair rule on restricted variations to 1 January 2027. We use the revised date and note the change.
How the report is generated
The report is a deterministic function of your inputs (headcount band, contract types, union flag). There is no free-form generated prose written at purchase time; the PDF is assembled from vetted, dated blocks. That is what keeps it accurate and consistent between the free checker and the paid report. The tranche dates are held as a single dated table, so when a date moves it is one edit that propagates through the whole product.
Freshness and re-verification
This whole product is a decaying asset by design, because the rollout is still landing. We re-read the government timeline update and the Acas page on a regular cadence, and before any significant change, and record each moved date on the timeline guide. Two dates we watch closely: the zero-hours and guaranteed-hours consultation closing 25 August 2026, and confirmation that the 1 October 2026 and 1 January 2027 tranches commence as stated. Every output is stamped with the date it was produced.
