Understanding the NMPA: Legal Background
The normal minimum pension age (NMPA) was introduced in 2006 at age 50 and increased to 55 in April 2010. The Finance Act 2022 legislated for the next increase to 57, effective from 6 April 2028. The NMPA applies to all UK registered pension schemes – defined contribution, defined benefit, personal pensions, and SIPPs alike.
The NMPA is not the same as the State Pension age. The State Pension age determines when you can claim State Pension from the government. The NMPA determines the earliest point you can access private and workplace pensions. The government’s policy is to keep the NMPA exactly 10 years below the State Pension age.
The Legislative Timeline
| Date | Event |
|---|---|
| 6 April 2006 | NMPA set at 50 under A-Day pension simplification |
| 6 April 2010 | NMPA increased from 50 to 55 |
| 11 February 2021 | Government consultation on increasing NMPA to 57 opens; this date becomes the reference point for protected pension ages |
| February 2022 | Finance Act 2022 receives Royal Assent, legislating for NMPA of 57 |
| 6 April 2028 | NMPA increases from 55 to 57 |
Protected Pension Ages in Detail
A protected pension age allows certain scheme members to retain a lower minimum access age even after the NMPA increases to 57. The rules are specific and technical:
Conditions for Protection
- The scheme rules as at 11 February 2021 must have included an unconditional right for the member to take benefits at an age below 57
- The member must have been a member of the scheme on 11 February 2021, or must have joined under a recognised block transfer
- The scheme must not have amended its rules after 11 February 2021 to remove or increase the protected age
What Counts as an Unconditional Right?
An unconditional right means the scheme rules explicitly stated that members could take benefits at a specific age (e.g., 55) without any conditions such as employer consent, trustee approval, or ill-health requirements. If the right was conditional, it does not qualify for protection.
Block Transfers
If your employer moved an entire group of employees from one pension scheme to another (a block transfer), the protection may transfer with the members, provided certain conditions are met. Individual transfers generally do not preserve protected pension ages.
Consequences of Accessing Before the NMPA
If you access your pension before the NMPA without a protected pension age or qualifying ill-health exemption, HMRC treats the payment as an unauthorised payment. The tax consequences are severe:
- Unauthorised payment charge: 40% tax on the amount withdrawn, payable by you
- Unauthorised payment surcharge: An additional 15% if the unauthorised payment exceeds 25% of the pension fund, payable by you
- Scheme sanction charge: Up to 40% payable by the pension scheme itself
In the worst case, you could face a combined tax charge of 55% on the entire amount, plus the scheme facing its own penalty. This is why it is critical to verify your access age before taking any benefits.
Ill-Health Early Access
The NMPA does not apply if you qualify for ill-health early retirement. There are two categories:
Serious Ill Health
If a medical professional confirms you are expected to live less than 12 months, you can take your entire pension as a tax-free lump sum (if under 75 and within the lump sum and death benefit allowance) regardless of your age.
Ill-Health Early Retirement
If you cannot carry out your current occupation due to physical or mental health conditions, many schemes allow early access. The criteria vary by scheme, and you will typically need medical evidence. The payment is treated as an authorised payment and taxed normally.
How SIPPs Are Affected
Self-Invested Personal Pensions (SIPPs) follow the same NMPA rules as any other registered pension scheme. From 6 April 2028, your SIPP provider will not allow you to access benefits before 57 unless you have a protected pension age that was explicitly preserved when you transferred into the SIPP.
If you are considering opening a new SIPP or transferring to one, check with the provider whether they can accommodate a protected pension age. Not all SIPP platforms have the administrative capability to manage different access ages for different members.
Planning for the Change
If you are affected by the NMPA increase, consider these planning steps:
- Verify your access age with every pension scheme you hold
- Avoid unnecessary transfers that could lose protection
- Build alternative savings (ISAs, general investment accounts) if you want income flexibility before 57
- Consider phased retirement – reducing work hours rather than stopping entirely
- Get professional advice – especially if you have multiple pensions with different access ages
