Every 3 years you need to check if you should put eligible employees who have left your pension scheme back into it. This is known as re-enrolment.
There are five steps to re-enrolment:
Your first re-enrolment date is three years after your original staging date, but you have the flexibility to set it at any day three months before or three months after this.

Any relevant eligible employees are put back on to your pension scheme on the re-enrolment date. From that date, you have six weeks to write to your re-enrolled employees.
It's a good idea to choose a re-enrolment date that aligns with your payroll, so it matches the start of your pay period. If you run more than one payroll, you might want to select a date where your payrolls align, as you can only have one re-enrolment date.
Your next re-enrolment date will be three years after your last re-enrolment date. Again, you can choose to set this any day three months before or three months after this date.

Who you need to re-assess
By law, you have to assess employees who opted out or ceased membership more than 12 months before your re-enrolment date.
Who you can choose to re-assess
You can choose to re-assess employees who opted out or ceased membership within 12 months of the re-enrolment date, but you are not obliged to do so.
You can also re-assess employees who have handed in their notice or have been given notice of dismissal, but there is no legal requirement to do this. If employees who have resigned decide to stay in your employment, you will need to include them in the assessment.
See more information on who you need to re-assess on The Pensions Regulator's website.
How you re-enrol employees on Smart Pension usually depends on how you submit contributions.
Option one - If you upload a file to submit contributions:
This template will contain the records for employees due for re-enrolment. Follow your normal process for calculating contributions. When you next upload your contributions file we’ll re-enrol any eligible employees.
Option two - if you manually enter contributions:
We'll also prompt you to re-enrol employees in your Smart Pension account's to-do list.
Option three - if you use PAPDIS or an API to submit contributions:
When your contributions are submitted to us via PAPDIS or API, we will add any employees eligible for re-enrolment back into the scheme.
We recommend you check with your payroll software provider if you are unsure about the process.
We will send your re-enrolled employees a confirmation email if we have their email address. If we don't, we'll generate a re-enrolment letter for you to give to them. You must give them this letter within six weeks of your re-enrolment date.
Your employees will then have the right to opt out of the scheme for one month from the date of the re-enrolment letter.
You must tell The Pensions Regulator you have re-enrolled your staff by completing a re-declaration of compliance.
You must do this within five months of the anniversary of when your automatic enrolment duties originally applied (staging date / duties start date) or your last re-enrolment date.
You need to complete a re-declaration even if you have no staff to re-enrol.
You can find a checklist of what you need to complete the re-declaration on The Pensions Regulator’s website.
