A workplace pension on a zero hours contract depends on your pay in each pay period: your employer must enrol you once you earn over the trigger (£192 a week in 2026/27) if you are aged between 22 and State Pension age.
A zero hours contract does not keep you out of auto-enrolment. Your age, whether you count as a worker and what you are paid in each pay period decide it, so a quiet month and a busy one can give different answers. A quiet fortnight can leave you under the trigger. An FCA-authorised adviser can examine your own shift pattern by phone, and the form on this page, kept short, is where to ask for that callback.
Do zero hours workers get auto-enrolled into a workplace pension?
Yes, when the age and pay tests are met. The Pensions Regulator (TPR) tells employers that duties apply even to short-term, seasonal and temporary staff without regular hours, if they are paid through a payroll. GOV.UK sets four conditions: being classed as a worker, an age from 22 up to State Pension age, yearly earnings of at least £10,000, and ordinarily working in the UK.
The Pensions Act 2008 words the pay test as earnings of "more than £10,000" payable "in the relevant pay reference period". With no fixed salary, that yearly figure becomes a figure for each pay period.
How is a zero hours worker assessed when pay changes every week?
The employer checks every time pay is run. Even where hours fluctuate, TPR says the employer "must assess them individually each time they run their payroll". With no usual gap between payments, TPR's detailed guidance treats the pay reference period as one week, which it notes is relevant to workers on zero hours contracts "who contractually are only paid when they do work".
For 2026/27 TPR shows the trigger as £10,000 a year, and the lower level of qualifying earnings as £6,240:
| Pay period | Enrolled above | Lower level |
|---|---|---|
| 1 week | £192 | £120 |
| Fortnight | £384 | £240 |
| 4 weeks | £768 | £480 |
| 1 month | £833 | £520 |
The upper level is £50,270 a year. DWP reviews these each year; TPR's page lists the 2025/26 and 2024/25 figures as the same.
One busy week can be enough: staff on irregular hours "should be enrolled the first time they earn over" the weekly or monthly figure, and TPR says a bonus that lifts a period's pay over the line has the same effect for that period.
What if you earn less than the trigger or fall outside the age range?
You have rights short of automatic enrolment. TPR's table sorts workers by pay and age:
- 22 to State Pension age, over the trigger: must be enrolled and the employer pays in.
- Over the lower level but not the trigger (over £120 up to £192 a week, or over £520 up to £833 a month): a right to opt in, after which the employer must put you into a suitable scheme and pay regular contributions.
- At or under the lower level: a right to join a scheme, without employer contributions.
- Aged 16 to 21, or State Pension age to 74, over the trigger: a right to opt in.
See pensions for younger workers and auto-enrolment after State Pension age for those groups.
Do you stay in the pension when your hours fall?
Generally yes. Once you are an active member of a qualifying scheme, TPR says none of the employer duties apply and the employer need only assess you again if that membership ceases.
The employer's payments are different. For irregular-hours staff, TPR says that if earnings fall below £120 a week or £520 a month, "the employer may stop paying contributions unless the rules of the pension scheme they have enrolled into require them to continue". Your scheme's own rules settle which applies. If they read as unclear, an adviser could go through them with you after a call-back request through the enquiry form.
You can opt out. GOV.UK says opting out within a month of being added gets back what you paid in, but later payments usually stay in the pension. An employer re-enrols you every three years or sooner if you still qualify; opting out of a workplace pension has the detail.
How much goes in when your pay varies?
GOV.UK says that in most schemes your contributions come from earnings between £6,240 and £50,270 a year, which include overtime, bonuses and statutory sick pay. Its table of minimums, in force since April 2019, is 3% from the employer plus 5% from you, 8% overall, and scheme rules can ask for more. The band applies to each pay period, so a high-pay week produces a bigger contribution than a quiet one. Read which pay counts toward contributions and minimum workplace pension contributions for the working.
Joining reduces take-home pay; GOV.UK says that may mean you qualify for an income-related benefit, or for more of one. Pension investments can fall as well as rise, so you may get back less than was paid in.
What if you have several jobs, work through an agency or are on a short contract?
Each employer assesses you separately. The Pensions Act 2008 says that where a jobholder has more than one employer, the chapter "applies separately in relation to each employment". Two jobs that each pay under the trigger may therefore leave you without automatic enrolment at either, whatever your combined pay. You would still have the right to opt in at any one paying over the lower level.
Several contracts with a single employer are a judgement for that employer: TPR says it must decide whether they operate as one employment relationship or as separate ones, and apply the duties to match.
If an agency pays you, the agency is the employer: TPR says an agency supplying staff to other businesses that are "responsible for paying these staff" must meet the duties.
For temporary staff who will stay under three months, an employer may postpone assessment, up to three months in most cases. The employer must tell you in writing, let you join meanwhile if you ask, and enrol you at the end if you are still there and meet the tests.
Zero hours and part-time pension queries
Do fixed-term and temporary workers qualify?
A fixed term does not rule you out. The same age and pay tests apply, with postponement available for short stays.
Do apprentices get auto-enrolled?
Yes, if the tests are met. The Pensions Act 2008 counts a contract of apprenticeship as a contract of employment, so an apprentice is a worker. From 22 the pay test decides; aged 16 to 21 and over the trigger, you have a right to opt in.
Can contractors join a workplace pension?
Auto-enrolment covers workers, and TPR says some "personal service workers" who invoice an employer can count as workers. See pension options for the self-employed if you run your own business.
What happens in a week with no shifts?
You stay a member; an empty pay period does not end your membership. With no earnings there is nothing for a percentage to be taken from, and while pay is under £120 a week the employer may stop contributing unless the scheme's rules require it to carry on.
