When Did the New State Pension Start?

Quick Scoop

  • The new State Pension started on 6 April 2016.
  • It applies if you reach State Pension age on or after that date and were born (roughly) after early 1951 (men) or early 1953 (women).
  • Anyone who reached State Pension age before 6 April 2016 stays on the old (basic + additional) State Pension.

Key Date: Start of the New State Pension

The “new State Pension” is the simplified, single-tier pension that replaced the older system of a basic State Pension plus additional earnings- related bits like SERPS and the State Second Pension.

  • Official start date : 6 April 2016.
  • From that date, people reaching State Pension age are assessed under the new rules rather than the old two-layer structure.

A helpful way to picture it is as a “line in the sand” on 6 April 2016: anyone crossing into State Pension age after that line is under the new system; anyone who crossed before stays under the old one.

Who the New State Pension Applies To

You come under the new State Pension if:

  1. You reach State Pension age on or after 6 April 2016 , and
  2. You are:
    • a man born on or after 6 April 1951 , or
    • a woman born on or after 6 April 1953.

Those born before those dates, who reached State Pension age earlier, are under the previous basic State Pension rules (with the possibility of Additional State Pension).

So, the new State Pension’s start is not about your date of birth alone, but specifically when you hit State Pension age relative to 6 April 2016.

Why 6 April 2016 Matters Now

Even in 2026, that 6 April 2016 start date still shapes what you get and how it’s calculated. Governments, financial advisers, and charities continue to distinguish “old” and “new” State Pension in guides and tools because:

  • It decides which rules apply to your entitlement and how transitional protections work.
  • It affects how any “protected payment” from the old system might sit on top of your new State Pension if you had built up a higher entitlement before 2016.

In short: if you’re trying to understand which State Pension you’re on, ask yourself when you reached State Pension age relative to 6 April 2016.
