How to Set Up a Workplace Pension Scheme That Meets UK Auto-Enrolment Rules

Every UK employer with at least one eligible worker must provide a workplace pension scheme and automatically enrol qualifying staff. It does not matter whether you run a two-person consultancy or a company with hundreds of employees — the auto-enrolment duties apply to you.

Despite being a legal requirement since 2012 (phased in over several years), workplace pensions still cause confusion for many small business owners. The process involves choosing a provider, setting up contributions, communicating with your team, and handling ongoing compliance. Miss a step and you risk fines from The Pensions Regulator (TPR).

This guide walks through the entire process from start to finish.

What is auto-enrolment?

Auto-enrolment is the government's system for ensuring that workers save for retirement. Under the rules, employers must automatically enrol eligible jobholders into a qualifying workplace pension scheme and make contributions alongside the employee.

An eligible jobholder is someone who:

• Is aged between 22 and the State Pension age
• Earns more than £10,000 per year (the earnings trigger)
• Works in the UK

Workers who do not meet all three criteria may still have the right to opt in to the scheme, or to request that you enrol them. The categories are:

• Non-eligible jobholders (aged 16 to 74, earning between the lower earnings threshold and the earnings trigger): Have the right to opt in, and you must make employer contributions if they do.
• Entitled workers (aged 16 to 74, earning below the lower earnings threshold): Have the right to join the scheme, but you are not required to make employer contributions.

Step 1: Know your duties date

Your duties start on the day you first employ someone. For new employers, this is the day your first member of staff starts work. TPR will write to you to confirm your duties start date (also called your staging date for employers who were caught by the original rollout).

If you have already been through the process and are now taking on new staff, you must assess each new employee and enrol them if they qualify.

Step 2: Choose a pension provider

You need to select a pension scheme that qualifies under the auto-enrolment rules. Most small businesses use one of the following:

• NEST (National Employment Savings Trust): The government-backed scheme designed specifically for auto-enrolment. It is free to set up and accepts all employers, regardless of size. NEST charges a 1.8% contribution charge on each payment, plus an annual management charge of 0.3%.
• The People's Pension: Another popular option for small businesses, with straightforward pricing and a simple online platform.
• NOW: Pensions, Smart Pension, or other commercial providers: Various providers compete on fees, fund performance, and ease of use.
• Existing pension providers: If you already have a group personal pension or stakeholder pension, check whether it meets the qualifying criteria for auto-enrolment.

When choosing a provider, consider:

• Setup fees and ongoing charges
• The quality of the online portal for both employer and employee
• Integration with your payroll software
• Fund choice and investment performance
• Customer support quality

Step 3: Set up contribution rates

The minimum contribution rates for auto-enrolment are:

| | Employee contribution | Employer contribution | Total | |---|---|---|---| | Minimum | 5% | 3% | 8% |

These percentages are calculated on qualifying earnings — the band of earnings between the lower and upper thresholds (currently £6,240 and £50,270 per year, though these figures are reviewed annually).

You can choose to calculate contributions on a different basis, such as total earnings from the first pound, as long as the overall contribution meets or exceeds the minimum requirements. Some employers find this simpler to administer because there is no need to calculate the qualifying earnings band.

Many employers contribute more than the 3% minimum as part of their benefits package. If you choose to do so, make sure your scheme rules and employee communications reflect the actual rates.

Step 4: Assess your workforce

Before your duties date, assess each worker to determine which category they fall into. For each eligible jobholder, you must:

1. Enrol them into the pension scheme
2. Write to them within six weeks to explain what has happened, how much is being contributed, and how to opt out

Workers who have the right to opt in should be informed of that right. Entitled workers should be told they can join the scheme.

This assessment is not a one-off exercise. Every time you take on a new employee, or when an existing worker's age or earnings change, you need to reassess their category.

Step 5: Process the first contributions

Once your employees are enrolled, you need to start collecting contributions from their pay and sending them to your pension provider, along with your employer contributions.

Most pension providers accept contributions via their online portal, a CSV file upload, or a direct integration with payroll software. The key is to submit contributions on time — typically by the 22nd of the month following the deduction (or the 19th if paying by cheque).

Late payment of contributions is a compliance failure that TPR takes seriously. Set up a process that runs alongside your payroll cycle to ensure contributions are calculated, deducted, and submitted in one smooth flow.

Using payroll software that integrates directly with your pension provider eliminates most of the manual work and reduces the risk of errors or late submissions.

Step 6: Handle opt-outs

Employees have the right to opt out of the pension scheme within one month of being enrolled. If they opt out within this window, you must refund any contributions already deducted from their pay and recover your own employer contributions from the pension provider.

You cannot encourage employees to opt out. TPR calls this an "inducement" and it carries heavy penalties. You must present auto-enrolment as the default and allow employees to make their own decision.

Employees who opt out must be re-enrolled approximately every three years. This is called cyclical re-enrolment, and it is your responsibility to manage the process.

Step 7: Complete your declaration of compliance

Within five months of your duties date, you must submit a declaration of compliance to TPR. This is an online form confirming that you have met your auto-enrolment duties, including which scheme you are using and how many employees you have enrolled.

Failure to submit the declaration on time can result in fines. TPR sends reminders, but do not rely on them — add the deadline to your calendar.

Ongoing duties

Auto-enrolment is not a set-and-forget process. Your ongoing obligations include:

• Assessing new starters and enrolling eligible jobholders
• Processing contributions accurately and on time each pay period
• Re-enrolling opt-outs every three years
• Re-declaring compliance every three years
• Keeping records for six years (or longer in some cases)
• Updating your scheme if contribution thresholds or minimum rates change

Common pitfalls

Delaying setup. TPR has enforcement powers including compliance notices, fixed penalty notices (starting at £400), and escalating daily penalties that can reach £10,000 per day for larger employers. Do not wait until you receive a warning letter.

Choosing the wrong earnings basis. If you calculate contributions on qualifying earnings but accidentally apply the percentages to total pay (or vice versa), you could be over- or under-contributing. Make sure your payroll system is configured correctly.

Forgetting about workers who become eligible. A part-time employee whose hours increase, or a young worker who turns 22, may suddenly become an eligible jobholder. Your assessment process should catch these changes automatically.

Not communicating clearly. Employees receive a lot of paperwork when they join a pension scheme. Make sure your communications are clear, timely, and compliant with the prescribed information requirements.

The bigger picture

Workplace pensions are one of the most valuable benefits you can offer as an employer. While the minimum contribution rates are relatively modest, they add up over a working lifetime — and many employees appreciate the employer contribution as a meaningful part of their total compensation.

Getting auto-enrolment right from the start saves time, avoids penalties, and demonstrates that you take your responsibilities as an employer seriously. Combined with effective payroll management, it becomes a routine part of running your business rather than a recurring headache.
