Armed forces pension overpayments and recovery demands

Why armed forces pension overpayments happen

An armed forces pension is not a single number pulled from one place. It is assembled from your service record, your representative or final pensionable pay, your scheme, your exit route, and then adjusted for anything unusual in your history. Each of those is a point where a wrong input or a wrongly applied rule can quietly inflate the figure, and because the pension is then paid month after month, a small error compounds into a large one before anyone notices.

The Forces Pension Society, which handles a large volume of these cases, describes the recurring causes as policy errors and miscalculations relating to:

• Pension sharing on divorce, where a pension debit was applied incorrectly or not at all. See pension on divorce.
• Early departure payments, where the EDP income or its step up at 55 was miscalculated. See the EDP guide.
• Guaranteed minimum payments, the contracted out element that interacts with your state pension.
• Guaranteed income payments, the AFCS award. See GIP.
• National Insurance adjustments, including the modification rules that apply to older service.

A separate and common mechanism is the annual increase being applied twice in a year. Pensions in payment rise each April with CPI, currently 3.8% from April 2026. If that uprating is applied once by the calculation and again by the payment system, the pension is permanently a little too high, and every subsequent year's increase compounds on top of the error.

What happens when an overpayment is found

Two things happen, usually in the same letter, and it is worth separating them because they are challenged differently.

1. Your future pension is corrected

The ongoing payment is reduced to what the scheme says it should always have been. This is not a penalty, and it is not negotiable in the way a debt is: if the corrected figure is right, that is your pension from now on. If you think the corrected figure is wrong, that is a dispute about the calculation.

2. The historic overpayment is recovered

The scheme also seeks to recover what it says it has already overpaid, typically by deducting a fixed amount each month over an agreed period. This is the part that is genuinely negotiable in its timing, and the part where the arguments about fairness sit.

The combined effect is what makes these cases so damaging. A pension can be cut to the corrected level and then reduced further while the historic sum is recovered, so the amount actually arriving each month falls twice, often by a large proportion of the total, and usually at a point in life when the recipient has no realistic way to replace the income.

Do you have to pay it back?

The MOD's stated position is that where payments have been made in genuine error, it has a responsibility to recover taxpayer funds, and that it will always seek to do so in a sensitive and proportionate way, including through tailored repayment plans and one to one financial and welfare support from veterans services.

That is the department's position, and as things stand no write off has been agreed, so a demand should be treated as live. But it is not the end of the matter, and there are three things worth being clear about.

• The demand is a calculation, and calculations can be wrong. The same administrative process that produced the overpayment produced the figure now being claimed back. You are entitled to see it.
• The repayment schedule is negotiable even where the debt is not. The MOD describes recovery as running through tailored repayment plans, which means the timetable is a conversation.
• There is a formal dispute route, and it exists precisely for this. The scheme's Internal Dispute Resolution Procedure lets you request detailed calculations and challenge maladministration or incorrect information, and the Pensions Ombudsman sits above it.

How to challenge a recovery demand

Work through this in order. Each stage generally expects the previous one to have happened.

Step 1: ask for the calculation in writing

Write to the Pensions Team at Defence Business Services, quoting the reference printed on your letter, and ask for a full breakdown: which element was wrong, which years are affected, what the correct figure should have been in each year, and how the total being claimed was arrived at. Keep a copy of everything you send and note the date.

Step 2: the Internal Dispute Resolution Procedure (IDRP)

If the answer does not satisfy you, use the IDRP. Write to the Armed Forces Pension Schemes Manager, DBS, Mail Point 610, Kentigern House, 65 Brown Street, Glasgow, G2 8EX, or email dbs-afpsi-authority@mod.gov.uk.

• Include your full name, service number, National Insurance number, address, telephone number and email.
• Attach as much supporting evidence as you can, including the original letter and any calculation you have been given.
• DBS aims to respond within 60 working days.
• IDRP covers pension scheme matters. It does not cover pay or employment issues.

Step 3: MoneyHelper

MoneyHelper, which absorbed the Pensions Advisory Service, gives free guidance on 0800 011 3797. It expects a complaint to have been made to DBS already, so this comes after IDRP rather than instead of it.

Step 4: the Pensions Ombudsman

The Pensions Ombudsman can investigate maladministration and make binding determinations. Call 0800 917 4487 or email enquiries@pensions-ombudsman.org.uk. Again, the internal procedure needs to have run first.

Negotiating the repayment itself

If the debt is established and correct, the remaining question is how it is recovered, and this is where there is real room to move. Recovery by monthly deduction over five years is not a fixed rule; it is one schedule among several.

When you discuss it, the useful things to put in writing are your actual monthly income and outgoings, any disability or health circumstances, and the practical effect of the proposed deduction on your ability to meet essential costs. The MOD's own description of the process refers to tailored repayment plans and to one to one financial and welfare support, so asking for both is asking for something the department says it offers.

It is also reasonable to ask what happens if your circumstances change during the recovery period, and to get the answer in writing.

This is not the McCloud under or overpayment line

Two different things share almost the same vocabulary, and mixing them up causes a lot of unnecessary alarm.

If your figure came from a Remediable Service Statement, read the statement guide rather than this page. If it came out of nowhere in a letter about a pension you have been drawing for years, you are in the right place.
