Automatic enrolment: who is enrolled and what must be paid in

Automatic enrolment is the legal duty on UK employers to put eligible workers into a workplace pension scheme and pay into it, without the worker having to ask. The duty was created by the Pensions Act 2008 and was introduced in 2012, with the full, nationwide rollout completed in April 2019¹. It exists because too many people were reaching retirement with nothing saved beyond the State Pension: the government's own assessment was that automatic enrolment would increase aggregate private pension incomes by £5 billion to £8 billion a year by 2050 (in 2011-12 earnings terms) and reduce government spending on income-related benefits to the retired by £0.9 billion³.

The rules are set in legislation and enforced by The Pensions Regulator, which is responsible for ensuring that employers comply with their automatic enrolment duties¹. By May 2026, 11,452,000 eligible jobholders had been automatically enrolled⁴. The headline numbers for an eligible worker are simple: you must be aged 22 to State Pension age, earning more than £10,000 a year, and working in the UK. A minimum of 8% of your qualifying earnings must go into the pension, of which at least 3% comes from your employer⁵.

What automatic enrolment is and why it exists

Automatic enrolment requires employers to enrol eligible employees into a workplace pension scheme¹. Before it existed, joining a workplace pension was usually a choice the worker had to make actively, and many never got round to it. The Pensions Act 2008 reversed the default: membership becomes automatic, and leaving becomes the active choice. The law gives a jobholder the right, by notice, to require an employer to arrange for them to become an active member of an automatic enrolment scheme, and it defines such a scheme as a qualifying scheme that satisfies prescribed conditions¹⁰.

The duty was phased in by employer size between October 2012 and February 2018, with the largest employers going first⁵. The government had committed to a broader review of automatic enrolment policy in 2017, which led to later changes, including the Pensions (Extension of Automatic Enrolment) Act 2023 giving the Secretary of State the power to reduce the lower age limit and remove the lower earnings limit of the qualifying earnings band⁵. A workplace pension set up to support the policy, NEST, was itself established under the Pensions Act 2008 as a qualifying scheme¹².

The scale of the change is visible in the compliance figures. By the end of August 2015, 58,000 employers had complied with automatic enrolment requirements¹³, and by May 2026 the number of eligible jobholders automatically enrolled had reached 11,452,000⁴. The Department for Work and Pensions originally estimated that around 28% of people would opt out of workplace pensions¹³, a measure of how strongly the default was expected to shape behaviour. The Pensions Regulator has also made clear that the duty reaches new forms of working: it has said that employers in the gig economy should recognise and comply with their automatic enrolment responsibilities voluntarily and promptly¹.

For most people, an automatically enrolled pension is a defined contribution workplace pension, where the money is invested until retirement. How these schemes are run and protected is covered in workplace pensions explained and master trusts.

Who is automatically enrolled: age 22 to State Pension age, earning over £10,000

Three conditions decide whether you are automatically enrolled. You must be aged between 22 and State Pension age; you must earn at least £10,000 per year; and you must work in the UK under a contract of employment or a work arrangement². The earnings trigger is precise: if you earn more than £10,000 a year, even one penny more, and you meet the other criteria, your employer will enrol you⁷. You must also not already be in a suitable workplace pension scheme⁵.

The age limits matter at both ends. If you are aged between 16 and 21, your employer will not automatically enrol you, but you have the right to join if you want, with both of you contributing and tax relief added⁷. The same applies at the other end of working life: if you have reached State Pension age but are under 75 and earn more than £10,000 a year, your employer will not automatically enrol you, but you can ask to join⁷.

Earnings are assessed on each job separately, not on your combined income. Employees who earn less than the £10,000 earnings trigger do not get automatically enrolled, and this affects more women than men because of their working patterns¹⁴. So a person with two jobs, each paying below the £10,000 trigger, is not automatically enrolled in either, even though their combined income may be well above it. Each employer can still be asked to join that employer's scheme.

One point about variable pay: if you get additional earnings, for example paid overtime, that means your pay in a single pay packet will be more than the threshold, your employer will automatically enrol you⁷. A bonus or an unusually large month can therefore trigger enrolment even if your basic salary is below £10,000.

Qualifying earnings: the band between £6,240 and £50,270

Contributions are not worked out on your whole salary. They are worked out on "qualifying earnings", a band of earnings between a lower limit and an upper limit. In 2025/26, employers must make contributions on earnings between £6,240 (the lower earnings limit) and £50,270 (the upper earnings limit)⁵. The lower limit of £6,240 is set in legislation¹⁵, and the same band figures appeared in 2022/23, showing how stable the band has been¹⁶.

In practice this means the first £6,240 of your earnings carries no pension contribution, and nothing above £50,270 counts either¹⁷. A worker earning £60,000 has contributions calculated on £44,030 (the £50,270 upper limit minus the £6,240 lower limit, both stated above).

The lower limit has long been criticised, because it means the lowest-paid workers get the smallest pension contributions relative to their total pay. The 2017 review of the policy proposed lowering the age threshold from 22 to 18 and removing the lower limit of the qualifying earnings band, so that contributions would be paid from the first pound of earnings⁵. The Pensions (Extension of Automatic Enrolment) Act 2023 gave the Secretary of State the power to do both, but the changes had not yet been brought into force as of the facts available here¹¹. A parliamentary inquiry launched in September 2026 is looking at whether minimum auto-enrolment contributions should increase, and if so, when, by how much, and how the cost of any increase is shared⁶.

Minimum contributions: 8% in total, at least 3% from your employer

The law sets a minimum total contribution of 8% of qualifying earnings, split between employee (5%) and employer (3%)⁶. Employers contribute a minimum of 3% and employees 5%, with the employee figure including tax relief⁵. Aviva, a major workplace pension provider, states the same rule for its schemes: based on qualifying earnings, the minimum contribution will be 8% and the employer will need to pay at least 3%¹⁸. A Treasury committee report puts it as employers making a minimum pension contribution of 3% of the employee's salary, as long as the employee does not opt out¹⁹.

The 8% is a floor, not a target. An employer can pay more, and many schemes are set up so that the employer pays some or all of what the employee would otherwise contribute. Some employers run their scheme through salary sacrifice, which changes how the contributions are taken and can reduce National Insurance for both sides. The dedicated page on auto-enrolment minimum contribution rates covers the detail, and workplace pension charges and the charge cap covers what schemes can deduct from your pot.

What the minimum means in cash depends entirely on where your pay sits in the qualifying earnings band. Because the band starts at £6,240, contributions are calculated on earnings between £6,240 and £50,270 rather than on full salary²⁰. A worker whose pay sits near the bottom of the band therefore sees smaller contributions in cash than the headline 8% percentage applied to their whole salary would suggest.

Tax relief on your contributions

Your share of the contributions attracts tax relief, which is why the employee minimum is described as 5% including tax relief⁵. How the relief reaches your pot depends on how the scheme is run, and the difference matters most to lower and higher earners: the pages on relief at source or net pay and pension tax relief explain the two methods.

The general rules on relief are set by HMRC guidance. You can get tax relief on private pension contributions worth up to 100% of your annual earnings²¹, and stakeholder pensions carry tax relief on contributions of up to 100% of your earnings each year, depending on the annual allowance²². Most personal pension providers will claim tax relief automatically for you at a fixed rate of 20%²³. Higher-rate taxpayers usually need to claim the extra relief themselves, which is covered in claiming higher-rate tax relief, and Scottish taxpayers have their own bands, explained in pension tax relief for Scottish taxpayers.

There is a limit on how much you can pay in each year before tax charges apply, covered in the pension annual allowance, and unused allowance from earlier years can sometimes be carried forward.

If you earn less or fall outside the age range: your right to opt in

Falling outside the automatic enrolment conditions does not close the door on a workplace pension. The law gives workers who are not eligible for automatic enrolment the right to ask to join, and if they do, the employer has to enrol them and pay into it²⁴. This applies to workers aged 16 to 21, workers who have reached State Pension age but are under 75, and workers earning £10,000 a year or less⁷.

There is one important exception on the employer's side. If a worker earns less than £6,240 a year and asks to join, the employer does not have to contribute, but can choose to do so²⁴. So a low earner who opts in may find the pension contains only their own money and tax relief. Anyone earning above £6,240 who asks to join is entitled to employer contributions as well.

The rules here may change. The 2017 review proposed lowering the age threshold from 22 to 18 and removing the lower limit of the qualifying earnings band⁵, and the Pensions (Extension of Automatic Enrolment) Act 2023 gave the Secretary of State the legal power to make both changes¹¹. Until those powers are used, the current thresholds stand. Workers who cannot join a workplace scheme, including the self-employed, can save for retirement through a personal pension or a SIPP, and pensions for the self-employed covers those options.

When you are enrolled and how postponement works

Employers can postpone a worker's automatic enrolment by up to 3 months if needed¹³. The legislation allows the deferral date to be any date in the period of three months after the starting day¹⁰. Postponement is most often used for short-term or seasonal workers, or for probationary periods, and the employer must tell you if it is being used.

Once you are enrolled, your employer has to tell you the start and end dates of the one-month opt-out period⁸. Contributions begin from your enrolment date, and it can take up to three months for money to be paid into your pension, so a short gap between the deduction appearing on your payslip and the money showing in your pot is not in itself a sign of a problem²⁰.

If you leave the job, the pension you have built up stays yours: what happens to your workplace pension when you leave a job explains your options at that point.

Opting out: the one-month window, and what you lose

You can choose to opt out of a workplace pension²⁴, but only after you have been enrolled in the first place, so you need to look out for the details of how to do it once your employer writes to you¹⁸. The opt-out window is one month, running from the date you were enrolled, and your employer has to tell you the start and end dates of that period⁸. If you opt out within the window, the contributions you have made are refunded.

After that month, the position changes. You cannot get a refund simply by changing your mind later, and the money already paid in stays in the pension. What you lose by opting out is substantial: your employer's contributions, which are at least 3% of qualifying earnings⁵, plus the tax relief on your own share²³. Opting out is therefore a decision with a real cost, and the page on how to opt out and get a refund covers the mechanics.

One group needs particular care before being enrolled at all. If you have enhanced protection or fixed protection and you are automatically enrolled into a workplace pension, you may lose that protection unless you opt out⁸. These protections relate to the old lifetime allowance rules, covered in the lifetime allowance and what changed when it was abolished.

Opting out is not permanent. Your employer must enrol you back in at least every 3 years if you have opted out and you are still eligible for automatic enrolment⁹, and Aviva confirms your employer will automatically enrol you back in once every three years if you are eligible, even if you have opted out¹⁸. You can also opt back in sooner: submit a request in writing, which can include an email, that is signed or, if by email, confirms you personally submitted it¹⁸. The page on re-enrolment covers the cycle in detail.

Where automatic enrolment does not apply

The duty applies to employees only. Unlike employees, automatic enrolment does not apply to self-employed people¹, a position confirmed in official statistics: those who are self-employed are not eligible for automatic enrolment². The government has looked at ways to reach them, but HMRC has said it was not actively considering auto-enrolling self-employed people through National Insurance¹, and it told a committee it had no current plans to introduce a facility for automatic enrolment into pensions as part of Making Tax Digital delivery¹⁶. The self-employed must therefore arrange their own saving, through a personal pension, a SIPP or other routes set out in pensions for the self-employed.

The employee-only rule also bites in the gig economy. Automatic enrolment only applies to employees¹, so workers whose engagements are classed as self-employed fall outside it, even where their working pattern looks much like a job. The Pensions Regulator's position is that gig economy employers should recognise and comply with their automatic enrolment responsibilities voluntarily and promptly¹, but the legal duty itself depends on employment status.

There is no separate rule for Northern Ireland in the facts here: nidirect, the Northern Ireland government service, publishes the same eligibility conditions, including the £10,000 trigger and the age bands⁷, so the thresholds described on this page apply across the UK.

Missing contributions or an employer not enrolling you: how to report it

If money has been deducted from your pay but has not reached your pension, or your employer has not enrolled you at all, there is a set route to follow. The first step is to speak to your employer. If you feel unable to do that, or you still have concerns after speaking to them, the matter can be reported to The Pensions Regulator²⁰.

For missing payments specifically, there are rules about timing. You can report it if your pension contributions have not been paid into your pension scheme for 90 days or more, and the regulator asks you to wait 90 days before reporting, because it can take up to three months for money to be paid into your pension²⁰. You must be ordinarily working in the UK to use the reporting route²⁰.

When you report, the regulator needs certain information:

• The name and address of your employer
• Your employer's PAYE number, if they have one
• How much money you think is missing and when it should have been paid
• Any evidence you have, such as payslips²⁰

The regulator uses the information you provide to assess whether your employer is meeting their automatic enrolment duties²⁷. If you have received a letter from your scheme provider telling you that your employer has already been reported to the regulator, you do not need to report it again, as the regulator is aware and investigating²⁰. The regulator has real teeth: it can impose civil penalties, undertake criminal prosecutions, or order relevant individuals to make payments into the scheme, and it has a new power to issue civil penalties of up to £1 million¹¹.

Complaints about how your pension is run

Alongside reporting an employer's failures, there is a separate route for complaints about how a scheme is managed. You can complain to MoneyHelper or the Pensions Ombudsman about how your workplace pension is managed²⁸, and you can make a complaint to The Pension Ombudsman if you are unhappy with how your employer or workplace pension scheme dealt with your situation²⁰. The Pensions Ombudsman can help if you have a complaint about your pension scheme¹⁷. The process is covered in The Pensions Ombudsman and complaining about a pension.

The Pensions Regulator regulates the way workplace pension schemes are run²⁸, and it also accepts reports in confidence if you think your employer or workplace pension scheme is involved in wrongdoing in an area it regulates¹⁷. Its stated focus as the regulator for workplace pensions is on ensuring savers' pension money is protected²⁹, and its strategy includes educating savers about pension scams, which it groups into seven kinds²⁹. Warning signs and where to get help are covered in pension scams.

Free, impartial guidance is available: MoneyHelper handles complaints questions and general pension guidance, and Pension Wise offers free guidance on your options once you reach the stage of taking money out.
