Following a long and bumpy journey through Parliament, the Employment Rights Act 2025 received Royal Assent on 18 December 2025, with some last-minute compromises most notably replacing the provisions which would have made unfair dismissal protection a day-one right, with a six-month qualifying period, but also a surprise removal of the statutory cap on unfair dismissal awards.
The Employment Rights Act 2025 is a key pillar of the Government’s Plan to Make Work Pay. The scope and significance of the 350-page Act should not be underestimated.
For the majority of the Act's provisions, the journey into becoming the law is still underway. Essential detail for many of the provisions is subject to further consultation with several provisions not expected to come into force until sometime in 2027 and perhaps beyond.
On 1 July 2025, the Department for Business and Trade (DBT) published a Policy paper, Implementing the Employment Rights Bill: Roadmap, setting out its planned timetable for future consultations and the coming into force of key measures in the ERA 2025. On 3 February 2026, this was updated in Policy paper: Implementing the Plan to Make Work Pay and Employment Rights Act (further updated 11 February 2026). Key changes include:
See our Key Provisions Implementation Quick Chart below.
In addition to the plethora of changes coming in under the ERA 2025, more reforms are under Government consideration, including:

Policy
A ban on 'exploitative' zero-hour contracts ensuring workers have a right to a contract that reflects the number of hours they regularly work. The ERA 2025 inserts new sections 27BA to 27BT into the Employment Rights Act 1996, resulting in complex provisions. The policy also includes giving workers "reasonable notice" of any shift changes and compensation for any cancelled or curtailed shifts.
Section 1: Right for qualifying workers to be offered guaranteed hours
Employers will be required to offer a guaranteed hours contract (GHC) to qualifying 'zero-hour' or 'low-hours' workers reflecting the hours they regularly worked at the end of every reference period. Essentially, the new right will apply to a 'zero' or 'low' hours worker who, during a relevant reference period, worked a number of hours that satisfy certain conditions in respect of number, regularity or otherwise.
For qualifying workers:
Important detail being is left to implementing regulations includes:
Section 2: Right to reasonable notice of a shift
When implemented, s2 ERA 2025 will require employers to provide workers with reasonable notice of when they require them to work and also reasonable notice if they need to cancel, change or rearrange a shift. This will apply to:
The second part of the definition appears to be intended to capture low-hours contracts. However, it also includes the possibility for contracts to be included based on a low level of guaranteed pay. It is not clear whether the hours threshold will be the same or different to a low-hours contract for the purposes of the duty to offer guaranteed hours.
Important detail on just what will amount to reasonable notice is being left to implementing regulations. At this stage we know:
Section 3: Right to payment for shifts cancelled, curtailed or moved at short notice
When implemented s3 will require employers to make payments to workers if they cancel, move or curtail a shift at short notice.
Employers will be under a duty to make a payment, of an amount to be specified in subsequent implementing regulations to a worker each time there is a cancellation, movement (i.e., a delay or bringing forward of a shift), or curtailment at short notice of a qualifying shift where any of the following apply:
*It should be noted that references to a request to work a shift made by an employer to a worker include a "multi-worker request" made by the employer to the worker and one or more others in circumstances where the employer does not need the shift to be worked by all of those to whom the request is made. But also note, a worker will not be entitled to payment unless, at some point prior, they reasonably believed that they would be needed to work the shift.
Curtailment of shifts can include hours being cut from the middle of a shift (in addition to the start and finish). The maximum amount of compensation for cancelled, moved and curtailed shifts is the amount that would have been earned save for the cancellation or curtailment and if moved what they would have earned for the original shift with such payments to be treated as 'wages'.
The duty to make payment applies to an individual who would be a worker if they worked the shift.
Any compensation payable for a cancelled, moved or curtailed shift will be taxable as employment income.
Important detail being left to implementing regulations includes:
Section 4: Agency workers guaranteed hours and rights relating to shifts
The rights to guaranteed hours contracts, reasonable notice of shifts and compensation for short notice changes to shifts will also extend to agency workers. Due to the complex relationship between an agency worker, agency and hirer, the zero hours contracts rights may apply differently to agency workers in certain respects. See "Agency Workers" below.
Section 5: Collective agreements contacting out
The rights to guaranteed hours, reasonable notice of shifts and compensation for cancelled, curtailed or moved shifts for zero hours, low hours and agency workers (see below) can be excluded by a relevant collective agreement. A relevant collective agreement is one which is in writing and made by, or on behalf of, one or more independent trade unions and the worker's employer. Contracting out on this basis can occur where the relevant terms of the collective agreement are incorporated into the contract, provided that the worker or agency worker has been notified in writing of the incorporation and effect of those terms. This has the potential to be a wholesale opt out or/and can apply to both workers and agency workers (in which case the collective agreement can be with the person who has the contract with the agency worker) and does not require the gap to be filled with comparable terms.
Allowing an employer and trade union to reach agreement on arrangements, will simplify compliance with the complex new provisions where agreement can be reached. This is the only basis upon which it is possible to contract out of these provisions. Accordingly, there is no opt-out route for non-unionised workplaces.
Section 7: Repeal of the Workers (Predictable Terms and Conditions) Act 2023
The 2023 Act was repealed in full on 6 January 2026.
Consultation
In the DBT Factsheet: Zero hours contracts, the Government states it:
Comment
The above provisions are intended to end one-sided flexibility, ensuring that jobs provide a baseline of financial security and contractual predictability so workers can better plan their lives and finances. We await the consultation on important elements such as what constitutes 'low hours' contracts and what will be the requirements of a 'guaranteed hours offer', the Government has stated it will also ensure that
But there are significant areas of uncertainty…
The 'who' question - guaranteed hours
Just where the threshold will be set for those considered to be working on a 'low-hours' contracts will significantly shape the impact of the guaranteed hours contract provisions. If a low threshold is set, for example at two hours per week (as some Conservative MPs argue), then many employers would simply guarantee workers two hours of work. If the threshold were to be set at 16 hours per week or even higher (as others argue), then the provisions will have much greater impact. Many part-time workers would be in scope and employers would have to monitor any additional hours they worked very carefully - a considerable administrative undertaking.
The 'who' question - shift notification
The need to offer a guaranteed hours contract will apply in relation to 'zero-hour' or (yet to be defined) 'low-hours' workers. However, the rights to shift notification/cancelations/curtailment and the corresponding compensation provisions apply to zero-hour workers and to workers who work under a contract 'of a specified description' requiring them to be provided with some work but without specifying the times or pattern of days and times of that work. We do not currently know what "of a specified description" will mean, but it appears that is not limited to the yet to be defined 'low-hours' workers. As such this may be wider.
The 'reasonable notice' of shifts question
What 'reasonable notice' of shifts is going to be is currently unknown. A presumption will operate that unless the contrary is shown, notice is not reasonable unless it is of the specified length, which has not yet been defined. Clearly, the longer the notice that is required, the greater challenges that employers will face with the shift notification provisions. Likewise, it is unknown what factors will be relevant to rebut the presumption. The factors that a tribunal must have regard to when determining whether reasonable notice was given are to be set out in regulations but again are as yet unknown.
Another potential issue arises where an employer puts out a call to workers seeking shift cover including multi-employee requests. If, for example, the employer states that the first three to respond will be given the shift, will the reference to the first three to respond be sufficient to amount to a 'cancellation of the shift'. Will the employer need to expressly comply with the cancellation requirements for any volunteers after the first three?
The 'reference period' question
What the reference period will be, is also an important issue for consultation. While the Act is silent on the definition of the 'reference period', in the "Next Steps to Make Work Pay" the Government favours a 12-week rolling reference period. The Bill states the initial reference period will be the period between the day when the worker is employed and "the specified day", for example the day at the end of 12 weeks as favoured by the Government. Subsequent reference period means "a period beginning and ending with the specified days". This may be a different length to the initial 12-week period, with periods such as 12-months for subsequent periods understood to be currently under consideration.
Note the use of the phrase "rolling reference period" differs from that used for calculating holiday pay for some irregular hours workers, but rather, there will be an initial reference period and then subsequent reference periods will start at the end of the initial period, with further reference periods only commencing after the end of the previous reference period adding to the administrative complexity. It should also be noted that each reference period starting date will be individual to the start date of the worker concerned again adding to the administrative complexity.
The 'seasonal variation' question
A particular hot topic in connection with the reference period question is how to account to for seasonal variations in workloads? This will be an important part for the future consultation. It should be remembered that zero-hours contracts are not being banned altogether. While employers will be required to make a 'guaranteed hours offer', it can be for a limited term where reasonable. Having said that, the employer will need to rebut the presumption that it is not for a limited term. Will significant seasonal variation be sufficient to rebut the presumption?
Worker's choice only
The worker will not be obliged to accept the offer, thereby retaining full flexibility on the worker's part. The Government states that it appreciates that zero-hours contracts can work well for some individuals, such as students and those with caring responsibilities, so those who are offered guaranteed hours will be able to remain on zero-hours contracts should they wish. As for the employer, the duty to make an offer of guaranteed hours will keep applying until the worker no longer satisfies the definition of a qualifying worker, which will only be when their contract guarantees more than a minimum number of hours to be specified in regulations (in other words, when they are no longer considered to be working under a zero-hours or low-hours contract). There are equivalent provisions for qualifying agency workers.
These provisions place on employers a rolling need to offer a GHC to workers including those who have confirmed they do not want a GHC, instead wishing to retain their existing flexible arrangement. This appears to be unnecessary bureaucracy however, the Government repeatedly rejected the use of agreements similar to those used in relation to the 48-hour working week.
Next steps
The one thing that is sure, is that the legislative provisions are extremely complex. We wait the further promised consultation on the outstanding detail.
Due to the complexity of these provisions and the number or outstanding issues it is not surprising that implementation is not expected until sometime in 2027.
Policy
The October 2024 Policy Paper, 'Next Steps to Make Work Pay' confirms this Bill will:
Next steps - consultation
On 18 March 2025, the Government commenced a consultation seeks views on how to implement mandatory ethnicity and disability pay gap reporting for large employers in Great Britain for employers with 250 or more employees: Equality (Race and Disability) Bill: mandatory ethnicity and disability pay gap reporting. The consultation closes on 10 June 2025.
A separate call for evidence will be published at a later date to seek views on other parts of the Bill, including making the right to equal pay effective for ethnic minorities and disabled people.
The consultation states that the Government’s aim is to use a similar reporting framework for ethnicity and disability to that already in place for gender pay gap reporting, which was introduced for large employers in 2017. It proposes to:
The Equality and Human Rights Commission will be responsible for enforcing the new pay gap reporting requirements.
In contrast to gender pay gap reporting, employees would be asked to self-report their ethnicity and disability status, with an option to opt out. The Government proposes using standardised ethnicity groupings. Given data protection considerations, it proposes a minimum of ten employees in any ethnic group being analysed. Smaller groups may need to be aggregated. It is proposed that all employers should report, at a minimum, a binary comparison, preferably between White British employees and all other ethnic minority groups combined.
Similarly, with disability reporting, a minimum of ten employees must fall in each group being compared. To avoid the risk of individual identification and the complexities of multiple impairments, the Government proposes that disability reporting should take a binary approach of only reporting differences between disabled and non-disabled employees, rather than by type of impairment.
Comment
As regards pay gap reporting, finding a methodology resulting in meaningful data is no easy task. The proposed approach set out in the consultation attempts to address difficulties that arise due to small statistical group issues and issues around classification of those of differing ethnicities/disabilities, but does this leave any meaningful data? How comparisons for identifying pay gaps across a wide range of race-based identities and very different forms of disability is challenging.
We expect there to be more changes coming for employment law in the next few months as the new governmental policies and legislation take shape.
