Should you buy additional pension in the Teachers' Pension Scheme?
The Teachers' Pension Scheme offers two ways to build more career average benefit: Additional Pension, which buys a stated amount of annual pension, and Faster Accrual, which increases the rate at which future service accrues. Both are purchases of guaranteed index-linked income, which is a different asset from a defined contribution pot.
- Additional Pension: buys a stated amount of annual pension, by lump sum or monthly payments.
- Faster Accrual: raises the accrual rate on future service, elected for a scheme year.
- What you get: index-linked income for life, with a survivor's element attached.
- The comparison: an inflation-linked annuity, not a fund — which is why the cost looks high.
01 The two routes
Additional Pension buys a defined amount of extra annual pension. You choose the amount, the scheme quotes a price based on your age, and you pay by lump sum or by monthly contributions over a chosen period. What you receive is a fixed addition to your annual pension, revalued and increased like the rest of it.
Faster Accrual works differently: you elect to accrue future service at a higher rate for a scheme year, paying a higher contribution rate for it. It applies to future service only and has to be elected within the scheme's timescales for each year.
Both are governed by the scheme regulations rather than by an investment provider, so the price is actuarially set rather than market determined.
02 What you are actually buying
The product is guaranteed, index-linked income for life with a survivor's element attached. That combination is not available on the open market at any comparable price — an inflation-linked joint-life annuity costs a great deal more per pound of income than a level single-life one.
So the honest comparison is against an annuity, not against a fund. Judged as an investment the cost looks high; judged as the purchase of the most valuable kind of retirement income it usually looks reasonable, particularly for someone who wants more of their retirement guaranteed.
Tax relief applies to the contributions in the normal way, since they are pension contributions through payroll, which lowers the effective cost by your marginal rate.
Shows: the lifetime value of buying additional annual pension, against its cost. Ignores: index-linking, the survivor's element, early retirement reductions, and tax relief on the contributions.
On the defaults above, the worked example shows £50,000. The cost is repaid after about 16 years of payments, before any inflation increases and before the survivor's element.

03 When it is worth doing
It suits someone who wants a larger guaranteed floor, has surplus income, and expects a long retirement — the three conditions under which index-linked income is worth its price. It suits a member with a spouse who has little pension of their own particularly well, because of the survivor's element.
It suits less well someone who wants flexibility, who may retire early and face reductions on the added pension too, or who has not yet captured other allowances. Filling an ISA or a SIPP first is often the better order for someone who values access.
As with any pension contribution, it counts against the annual allowance, and for a long-serving teacher the pension input amount can be larger than expected — so the allowance position is worth checking before committing to a multi-year purchase.
Judge this against an annuity, not against a fund, and it stops looking expensive. What you are buying is inflation-linked income for life with a survivor's pension attached, and nothing on the open market sells that combination at a comparable price. The people it suits are those who want more of their retirement guaranteed and have the surplus income to buy it. The people it does not are those who might retire early — the added pension is reduced too — and those who have not yet used their ISA and SIPP allowances, where flexibility is worth more than certainty.
FAQ
What is the difference between Additional Pension and Faster Accrual?
Additional Pension buys a stated amount of extra annual pension, paid for by lump sum or monthly. Faster Accrual raises the rate at which future service accrues, elected for a scheme year at a higher contribution rate.
Is it good value?
Compared against an inflation-linked joint-life annuity on the open market, generally yes — that combination is expensive to buy commercially. Compared against a fund it looks costly, but a fund does not provide guaranteed income for life.
Does it count against my annual allowance?
Yes. The contributions form part of your pension input amount for the year, and for a long-serving member that figure can be larger than expected. It is worth checking the allowance position before committing to a multi-year purchase.
