Eleanor StoneAsda / GMB Pay Agreement 2026–2027: A Complete Guide for Workers (2026)
What Is the Asda / GMB Pay Agreement?
The Asda / GMB Pay Agreement is the collective bargaining agreement (CBA) negotiated between Asda Group Ltd and the GMB union on behalf of approximately 130,000 store colleagues across the United Kingdom. It establishes the pay rates, working conditions, and employment protections that govern day-to-day working life for the majority of Asda's retail workforce — making it one of the largest private-sector collective agreements in British retail.
GMB became the recognised trade union for Asda store workers following Asda's separation from its former parent company Walmart, which was completed when TDR Capital and the Issa brothers — owners of the EG Group petrol-station and convenience business — acquired the supermarket chain. Under the Trade Union and Labour Relations (Consolidation) Act 1992 (TULRCA 1992), recognised unions have the legal right to bargain collectively on matters such as pay, hours, and holiday entitlement. This formal recognition gives GMB members at Asda significant legal protection and a direct voice in determining the terms of their employment.
The current agreement runs from 1 March 2026 to 28 February 2027. Alongside the headline pay rate, the agreement sets terms around working hours, annual leave, redundancy, notice, and access to the workplace pension — all of which are explained in full below.
Pay and Pay Award 2026
Asda's headline pay rate for store colleagues rose to £13.15 per hour with effect from 1 March 2026. This represents Asda's annual pay award and applies to the majority of hourly-paid store colleagues across the UK.
The rate of £13.15 per hour sits £0.94 above the National Living Wage (NLW) of £12.21 per hour, which came into force from April 2026 following the government's 9.9% uplift — the largest single-year increase to the NLW since it was introduced in 2016. Whilst the NLW is a statutory minimum applying to workers aged 21 and over under the National Minimum Wage Act 1998, Asda's negotiated rate exceeds it, providing a meaningful premium above the legal floor for all eligible colleagues.
Asda also operates an enhanced rate for stores within the M25 orbital motorway to reflect London's higher cost of living. Since October 2025, the M25 supplement had already brought the London rate above the national figure; the March 2026 award extended that differential further. Colleagues working at M25 stores should check their most recent payslip or contract to confirm their applicable rate.
The Context Behind the Deal
Asda's ownership by TDR Capital and the Issa brothers has seen the employer commit in excess of £415 million to pay improvements since the acquisition of the business from Walmart. The year-on-year increase from £12.60 (October 2025) to £13.15 per hour represents a further step in that commitment, and places Asda's basic rate above the statutory minimum by a margin that GMB has acknowledged as meaningful — even as the union continues to press for further improvements.
The Phasing Dispute
One longstanding tension between GMB and Asda concerns the timing of pay awards. GMB has consistently argued that pay increases should be consolidated from a single effective date at the start of the agreement year, rather than being phased across the year with intermediate uplift points (as occurred in 2025, with increases in both July and October). The union's position is that a single March uplift date is more transparent, easier for colleagues to understand, and eliminates the practical difficulty of calculating back pay for those who changed hours or contracts mid-cycle. This issue remains an active matter of negotiation between the parties.
Working Hours and Leave Entitlement
Asda store colleagues are covered by the Working Time Regulations 1998 (WTR 1998), which set the statutory floor for working time protections in the United Kingdom.
Annual Leave
Under WTR 1998, the minimum statutory entitlement is 28 days of paid annual leave per leave year (inclusive of bank holidays) for a worker engaged on a standard five-day week. This is equivalent to 5.6 weeks multiplied by the number of days ordinarily worked per week. Part-time colleagues receive the same entitlement calculated on a pro-rata basis.
Asda's agreed terms provide annual leave entitlements consistent with this statutory minimum, and some roles or lengths of service may attract additional leave above 28 days. Workers should check their individual contract of employment or speak with their line manager or GMB representative to confirm the precise entitlement applicable to their role and service length.
Bank Holidays
The United Kingdom recognises eight public bank holidays in England and Wales (nine in Scotland, ten in Northern Ireland). These are ordinarily included within the 28-day WTR 1998 minimum. Because Asda operates retail stores seven days a week throughout the year, colleagues required to work on bank holidays are typically entitled to enhanced pay or time off in lieu — the specific terms being set by the agreement and the store's rota arrangements.
Rest Breaks
WTR 1998 entitles workers to a minimum uninterrupted rest break of 20 minutes for any shift exceeding six hours. Workers are also entitled to a minimum daily rest period of 11 consecutive hours between shifts, and a minimum weekly rest of 24 uninterrupted hours (or 48 hours per fortnight, at the employer's election).
Redundancy Pay
If Asda were to make a colleague redundant, the starting point is the statutory redundancy payment formula set out in the Employment Rights Act 1996 (ERA 1996). The amount payable depends on three factors:
- Age at the date of dismissal
- Completed years of continuous service (up to a maximum of 20 years)
- Gross weekly pay, capped at £700 per week (the 2026 statutory cap)
The ERA 1996 formula is:
| Age band | Rate per qualifying year |
|---|---|
| Under 22 | 0.5 week's pay |
| 22 to 40 | 1 week's pay |
| 41 and over | 1.5 weeks' pay |
Worked example: A 45-year-old colleague earning £13.15 per hour on a 37.5-hour contract (gross weekly pay ~£493) with 9 years' continuous service would receive:
- 9 years × 1.5 weeks (age 41+) × £493 = ~£6,655 in statutory redundancy pay
The weekly pay cap of £700 means that no more than £700 per qualifying week may be counted, regardless of actual earnings above that figure. The maximum statutory redundancy payment in 2026 is therefore £21,000 (20 years × 1.5 × £700).
Where GMB has secured collectively agreed provisions above the statutory minimum — such as an enhanced multiplier, a longer qualifying period, or a higher pay cap — those contractual enhancements would be payable in addition to or instead of the statutory sum. Colleagues should ask their GMB workplace representative whether enhanced redundancy terms have been agreed at their site. Statutory redundancy payments are generally exempt from income tax up to £30,000 under the Income Tax (Earnings and Pensions) Act 2003.
Notice Period
ERA 1996 s.86 sets the statutory minimum notice that an employer must give an employee before terminating their employment. The statutory minimums are:
- 1 week's notice for each full year of continuous service
- Up to a maximum of 12 weeks (for 12 or more completed years of service)
- A minimum of 1 week regardless of length of service, once an employee has been continuously employed for at least one calendar month
Employees are required to give their employer a minimum of one week's notice once they have been employed for one month or more, unless their contract requires a longer period.
Asda's individual contracts of employment may specify contractual notice periods that exceed the ERA 1996 statutory minimum — for instance, a requirement to give or receive four weeks' notice. Where a contractual period is more generous than the statutory minimum, the contractual term takes precedence. Colleagues unsure of their notice entitlement should check their written statement of employment particulars, which ERA 1996 s.1 requires employers to provide no later than the first day of employment.
Pension Rights
As a private-sector retail employer, Asda operates its workplace pension under the auto-enrolment framework introduced by the Pensions Act 2008. This framework requires employers to automatically enrol eligible workers into a qualifying pension scheme without the worker needing to take any action.
Who Is Eligible?
Eligible workers are those:
- Aged between 22 and State Pension age
- Earning above the auto-enrolment earnings threshold (currently £10,000 per year gross)
- Working or ordinarily working in the UK
Workers aged 16–21 or above State Pension age, and those earning below the threshold, may ask to be enrolled voluntarily, in which case the employer must also contribute.
Contribution Rates
| Contributor | Minimum rate (Pensions Act 2008) |
|---|---|
| Employee | 5% of qualifying earnings |
| Employer (Asda) | 3% of qualifying earnings |
| Combined minimum | 8% of qualifying earnings |
Asda's scheme may provide employer contributions above the statutory 3% minimum. Higher employer contributions represent a significant benefit over and above the headline hourly rate, and colleagues are encouraged to review their pension statements to understand the total value of their remuneration package.
Workers may opt out of the scheme within one month of enrolment, but doing so forfeits the employer contribution. Under the Pensions Act 2008, Asda is required to re-enrol opted-out workers approximately every three years.
Your Rights Under the Agreement
The Asda / GMB Pay Agreement, supported by UK employment legislation, gives you the following core entitlements:
- Pay above the statutory minimum: Your hourly rate of £13.15 per hour (from 1 March 2026) exceeds the National Living Wage of £12.21, providing a negotiated premium above what the law alone requires under the National Minimum Wage Act 1998.
- Collective bargaining representation: Under TULRCA 1992, GMB has the legal right to negotiate on your behalf. You have the right to join the union, to be represented by a GMB representative in disciplinary, grievance, and redundancy proceedings, and to take part in lawful industrial action.
- Statutory redundancy protection: ERA 1996 guarantees you a minimum redundancy payment based on your age, length of service, and weekly pay, should your role be made redundant. Any collective enhancement agreed by GMB adds to this floor.
- Auto-enrolment pension contributions: Under the Pensions Act 2008, Asda must contribute a minimum of 3% of your qualifying earnings to your pension scheme, matching your own 5% contribution.
- Working time protections: WTR 1998 guarantees minimum rest breaks, daily and weekly rest, and 28 days' paid annual leave. All these protections are directly enforceable against your employer.
If you believe any of these rights have been breached, you should raise a formal grievance under Asda's internal grievance procedure, or contact your GMB workplace representative for guidance. Claims under ERA 1996 and WTR 1998 may ultimately be brought to an Employment Tribunal, subject to strict time limits — ordinarily three months less one day from the act complained of.
Frequently Asked Questions
Q: When did the £13.15 hourly rate take effect? The rate of £13.15 per hour for store colleagues took effect on 1 March 2026, the start of the 2026–2027 agreement period.
Q: Does the £13.15 rate apply to all Asda workers? The headline rate applies to the majority of hourly-paid store colleagues across the UK. An enhanced rate applies to stores within the M25 area. Specialist roles — such as pharmacy technicians, security colleagues, or petrol-station operatives — may attract different rates; check your individual contract or speak to your GMB representative.
Q: I work part-time — do I get the same hourly rate? Yes. The right to receive at least the National Living Wage, and Asda's negotiated rate above it, applies regardless of whether you work full-time, part-time, or on a zero-hours contract. Part-time workers are entitled to the same pro-rata annual leave and proportionate redundancy entitlements under WTR 1998 and ERA 1996 respectively.
Q: The October 2025 pay increase was different from the March 2026 one — what is the relationship? Correct. The October 2025 rate (£12.60 per hour) was the second phase of Asda's 2025 pay award. The March 2026 rate of £13.15 per hour is the first (and intended to be the only) phase of the new 2026–2027 agreement. GMB has long argued for a single annual uplift date to replace the multi-phase approach used in prior years.
Q: How do I raise a dispute about my pay? First raise the matter informally with your line manager. If unresolved, submit a formal written grievance under Asda's grievance policy — you are entitled to be accompanied to any formal meeting by a GMB representative or a workplace colleague under ERA 1999 s.10. GMB can also escalate unresolved collective disputes through the formal dispute resolution process under the recognition agreement.
Q: Am I entitled to enhanced redundancy if Asda makes me redundant? You are guaranteed the statutory redundancy minimum under ERA 1996. Whether GMB has negotiated enhanced terms above that floor depends on the current agreement at your site. Contact your GMB workplace representative before accepting any settlement to ensure you receive your full entitlement.
