My Lords, it might be helpful if I explain the principle behind having protected payments. We recognise that some people who will reach pensionable age under the single tier will already have amounts of additional pension which take them over the full single-tier rate. A key consideration in the design of the transition was that this extra would not be taken away. Revaluing the protected payment, at least by increases in prices, will maintain its purchasing power over time.
Let me deal directly with the point made by the noble Lord, Lord Whitty, about fairness in relation to expectations. Under the current system, the additional state pension is revalued up to state pension age in line with average earnings, but is then indexed only by prices once in payment. A man retiring in the first 10 years of single tier could expect to spend, on average, 20 years in retirement. In single tier, we have shifted this balance between adjustments before and
after pensionable age, and the majority of people receiving protected payments will be better off overall as a result of this shift.
In the current system, only basic state pension is uprated by a minimum of earnings. In the future, the full amount of the single-tier pension would be uprated in this way. So using the 2012-13 White Paper figures, this means that people will see the illustrative £144 of their state pension being uprated each year by earnings, or more—potentially the triple lock—not just £107. People with a protected payment will be relatively close to pension age, so the revaluation will typically be applied only for a few years. So, for example, even someone with an above average protected payment of £20 with 10 years left until they reach retirement would find that revaluation leaves them £4 per week worse off upon reaching pensionable age, but £4 better off 10 years later.
The amendments tabled by the noble Baroness, Lady Turner, and the noble Lord, Lord Whitty, would effectively incorporate earnings revaluation of the protected payment into single tier. As this is a cost-neutral package of reforms, we would need to make offsetting changes elsewhere. Given that we expect most people to be better off from the combined revaluation and uprating changes, this would be difficult to justify. To give noble Lords a response to their question about the costs we are talking about, I can tell them that using earnings to revalue the protected payment would have annual costs, which would peak at around £150 in about 2040.
