GMP is the minimum amount of pension you must, by law, receive from your pension scheme if you worked between 6 April 1978 and 5 April 1997.
How GMP affects you
Anyone who worked between theses dates would have been contracted out of the State Earnings Related Pension Scheme (SERPS). This includes the NHS Pension Scheme.
Your GMP forms part of your pension from the date you become eligible to receive your state retirement pension.
Your GMP amount
Your GMP amount is broadly equivalent to what you would have received if you had been in the State Earnings Related Pension Scheme for that period of service.
Your pension will:
- usually be larger than the guaranteed minimum
- include your GMP amount, it is not an extra amount to be paid
- be increased up to the GMP amount if it is smaller than the GMP amount
The amount of GMP varies from person to person depending on earnings on which you have paid contracted out National Insurance contributions.
How your GMP is applied
The Pensions Service, which is part of the Department for Work and Pensions (DWP), will write to you when you near state pension age and tell you how much your weekly GMP is. They will also notify us.
We convert the weekly amount to an annual amount.
NHS Pensions are subject to an annual increase which is based upon the Consumer Price Index (CPI) as laid down by HM Treasury every year. This increase is applied at the beginning of April in the new tax year.
For details on how Pensions Increase and GMP are applied please read the Retirement Guide.
