A pension provider may run the scheme and a payroll bureau may calculate deductions, but the legal duties still belong to the employer. Problems usually arise at ordinary employment events: a new starter is not assessed, variable pay crosses a threshold, a postponement letter is late, or a three-year re-enrolment date is missed. This guide gives UK SME employers a practical control process for the current 2026/27 rules.
Identify who must be assessed
Automatic enrolment duties can apply as soon as an organisation employs a worker. The Pensions Regulator uses a wider test than simply checking who is labelled an employee: a worker can include someone contracted to perform work or services personally who is not genuinely operating their own business. Put the status decision into onboarding rather than relying on the payroll category alone.
An eligible jobholder must normally be automatically enrolled if they work or ordinarily work in the UK, are aged at least 22 but below State Pension age, and have qualifying earnings above the automatic-enrolment trigger in the relevant pay reference period. Other workers aged 16 to 74 may have a right to opt in or join. An employer contribution is generally required when a jobholder opts in, while an entitled worker can join a scheme without a compulsory employer contribution.
Assessment is not finished on day one. A 21-year-old turns 22, a part-time employee receives overtime, or a seasonal worker's pay increases. Payroll must recognise the trigger and start the correct process. A monthly spreadsheet reviewed once a year will not reliably do that.
Use the 2026/27 thresholds in the correct pay period
For 2026/27, the annual automatic-enrolment earnings trigger is £10,000. The lower and upper qualifying-earnings levels are £6,240 and £50,270. For monthly payroll, the corresponding figures are £833, £520 and £4,189; for weekly payroll they are £192, £120 and £967. These figures serve different purposes: the trigger helps decide whether someone must be automatically enrolled, while the qualifying-earnings band is commonly used to calculate minimum contributions.
Do not decide eligibility by dividing an annual salary informally. Assess earnings payable in the relevant pay reference period, using the correct period threshold and the scheme's certification basis. Variable overtime, bonuses, commission, statutory payments and changes in hours can affect the result. Ask the pension provider or payroll adviser how the scheme defines pensionable pay and document the answer.
For a typical defined-contribution scheme using qualifying earnings, the minimum total contribution has been 8% since 6 April 2019, with at least 3% from the employer. A scheme can use a different compliant basis or require more. Check the scheme rules before promising that a headline percentage will produce a particular deduction or pension outcome.
Use postponement as a controlled delay, not an exemption
An employer can postpone assessment for up to three months from its duties start date, a worker's first day, or the date a worker first meets the age and earnings criteria. This can help with short-term or probationary appointments and payroll setup, but it does not move the employer's duties start date or declaration deadline.
Choose the deferral date, issue the required written notice to each affected worker within the statutory window, and diarise the assessment for the last day of postponement. The Regulator's current employer guidance says the notice must be sent within six weeks from the day after postponement starts. A worker's right to ask to join during postponement remains; where the conditions are met, the employer must act and contribute.
Do not roll a worker automatically into another postponement at the deferral date because administration is unfinished. Assess them, enrol them immediately if eligible, and retain the notice and decision evidence.

Discuss an auto-enrolment processKeep opt-outs separate from management pressure
Eligible workers must be enrolled before they can opt out. The opt-out period is normally one month from active membership or receipt of the enrolment information, whichever is later. Process a valid notice through the scheme's route, stop deductions and arrange the required refund. A request made after that period may instead be a request to cease membership under the scheme rules.
Managers must not ask applicants whether they plan to opt out, imply that recruitment depends on doing so, or offer an incentive whose main purpose is to make a worker leave the scheme or reduce contributions below the minimum. Keep pension-choice conversations factual. The employer explains the process; the worker makes the decision.
A Gateshead employer with tight labour costs cannot solve a budget issue by presenting opt-out forms with starter paperwork or suggesting that everyone will take home more if they sign. Cost the employer contribution before recruitment and let the authorised scheme process protect the worker's choice.
Build re-enrolment and records into the calendar
Every three years, employers must assess certain staff who left the pension scheme or reduced contributions and put eligible people back into a qualifying scheme. The employer chooses a re-enrolment date within its permitted window and then completes a re-declaration of compliance. The re-declaration is required even if nobody needs to be re-enrolled.
The first declaration of compliance is normally due within five calendar months of the duties start date. Outsourcing the task does not transfer accountability. Keep the employer contact, PAYE details, scheme reference, worker assessment and contribution information current so a bureau or adviser can complete accurate submissions.
Most automatic-enrolment records must be retained for at least six years; opt-out records must be kept for four. Records include worker and scheme information and the original form of statutory notices, which may be stored electronically if legible. Make retention part of payroll closure and provider-change planning rather than relying on access to a former bureau's portal.

Employer auto-enrolment control checklist
- Confirm which employees and personal-service workers are within the assessment process.
- Load the correct 2026/27 thresholds for each payroll frequency.
- Assess new starters and monitor age, earnings and status changes every pay period.
- Check the scheme's contribution basis and minimum employer contribution.
- Issue postponement and enrolment communications within the required times.
- Let the pension scheme process opt-outs without manager influence.
- Diarise the three-year re-enrolment window and re-declaration deadline.
- Retain six-year compliance records and four-year opt-out records in a retrievable format.
Treat automatic enrolment as a payroll control with HR inputs, not a form completed once when the scheme opens. Name an owner, assess the actual pay period, record notices and exceptions, and test the process at every starter, earnings change and three-year re-enrolment cycle.
