Once an active member of the pension scheme has left service the scheme trustees are obliged to revalue the GMP element of the pension from the date they left the scheme to the date of retirement.
There are three ways of applying the revaluation to the GMP in deferment. They are:
Section 148 orders
Section148 orders revalue the guaranteed minimum pensions broadly in line with the National Average Earnings. A different rate of revaluation will therefore be applied for each complete tax year between leaving and GMP age (65 males, 60 females).
Limited revaluation
Limited revaluation is revaluation in line with Section 148 orders, limited to a maximum of 5% per annum.
When a scheme applied limited revaluation a ‘Limited Revaluation Premium’ (known as a LRP) was paid to the Department of Social Security by the scheme when a member left service. This covered the estimated cost of the state providing any increases above 5%, up to full revaluation under Section 148 orders.
Limited revaluation was abolished for leavers on or after 6 April 1997. However, it is still possible for preserved pension accrued before 6 April 1997 to have limited revaluation applied to the GMP element.
Fixed rate
When applying a fixed rate GMP revaluation the rates are provided by the Government Actuary and are intended to be equivalent to the future increases in Section 148 orders. The rates are adjusted every few years* to reflect changing economic conditions. The revised rate applies to all leavers after that date of change and the GMP will be revalued over the number of complete tax years between the member's date of leaving and state pension age.
If National Average Earnings exceeds the fixed rate of revaluation applicable to the leaver, the government will make up the difference.

In general, Statutory Style Schemes (eg Local Government Pension Scheme or NHS etc) will revalue their members' GMP by Section 148 orders and escalate it in payment by statutory minimum. This method is not often used in private sector schemes as the liability to the trustees would be unknown and unlimited.
As a result, most private sector schemes will revalue GMPs by the fixed rate in deferment and statutory minimum in payment.
Historically, some schemes may have offset statutory revaluation on the GMP against other scheme benefits rather than add them to the member's deferred entitlement. This meant the total was lower as the statutory increases were incorporated into the other benefits as a replacement for part of them, rather than being added on top. This practice was known as full franking, and was forbidden for leavers on or after 1 January 1985.
In some cases, partial franking may be applied by the scheme. The most common occurrence is when the scheme retirement age is before GMP age, and the increases granted under the scheme to a pension in payment are offset against the GMP revaluation between retirement and GMP age.
