You paid into it for years. It showed up on your payslips, or it quietly did not, and now you are living abroad and trying to work out what the UK actually owes you. Somewhere in the back of your mind is a word from an older world of work: SERPS.
The good news is that the earnings you built up under it were not cancelled. The confusing news is that where it lands now depends on a single date, and for a large number of people the answer is that it is already sitting inside a figure they have looked at without realising what it contained.
This article explains what SERPS was, what replaced it, how to tell whether you were contracted out, and what all of it means once you are drawing a UK State Pension from overseas.
SERPS stands for the State Earnings-Related Pension Scheme. GOV.UK records that it ran from 1978 to 2002.
The idea was straightforward. The basic State Pension paid a flat amount to everyone with a sufficient National Insurance record, regardless of what they had earned. SERPS added a second layer on top, related to what you actually earned as an employee. Two people who retired in the same year with the same number of qualifying years could receive different totals, because one had earned more during the SERPS era and had built up more of that second layer.
Eligibility for the SERPS portion was tied to employment. GOV.UK's condition for that period is simply that "You were employed". The self-employed did not build up SERPS.
SERPS did not survive on its own. GOV.UK records that the State Second Pension ran from 2002 to 2016, taking over from SERPS.
The State Second Pension widened the net. Where SERPS required employment, the State Second Pension covered employees "earning at least the lower earnings limit" and also extended to people who were not in paid work at all, including those "looking after children under 12 and claiming Child Benefit" and those "caring for a sick or disabled person more than 20 hours a week and claiming Carer's Credit".
Both schemes sit under one umbrella term. GOV.UK is explicit that "The Additional State Pension was also known as State Second Pension or 'SERPs'." If you have found three different names in three different letters, that is why. They are describing the same layer of the system at different points in its life.
This is the part that generates most of the confusion, and it turns on one threshold.
GOV.UK states that the Additional State Pension is paid to "a man born before 6 April 1951" or "a woman born before 6 April 1953". That is the group who reached State Pension age before the new State Pension began on 6 April 2016.
If you are in that group, your SERPS reaches you the way the old system intended. GOV.UK confirms that "The Additional State Pension is paid with your basic State Pension", and that "You get the Additional State Pension automatically if you're eligible for it, unless you've contracted out of it." You see a basic amount and an additional amount, and the additional amount is where your SERPS lives.
If you reach State Pension age on or after 6 April 2016, you are on the new State Pension instead. GOV.UK is direct about this: people who "reached State Pension age on or after 6 April 2016" receive "the new State Pension". There is no separate SERPS line, and no separate SERPS payment.
That absence is what makes people think theirs was lost. It was not. The years you spent building SERPS are folded into the starting amount used to work out your new State Pension, and you see the result as one figure. The full rate of new State Pension is £241.30 a week. GOV.UK notes that "If your National Insurance record started after April 2016 you will need 35 qualifying years to get the full rate of new State Pension", which is precisely the case where no SERPS is involved at all. Anyone with a record stretching back before 2016 is being assessed under a transitional calculation that takes the old system into account.
Alongside SERPS ran an arrangement that shaped millions of records, and it explains why two people with apparently identical careers can see very different numbers.
GOV.UK describes it plainly: "Under the State Pension rules before 2016, you or your workplace or private pension scheme could choose to 'contract out' of the Additional State Pension."
Contracting out meant stepping outside that second layer. In exchange, one of two things happened. GOV.UK states that if you were contracted out, some of your National Insurance contributions were either "lower than people who were not contracted out" or "paid into another pension, for example a workplace or private pension".
That second limb is the one worth pausing on. Money that would have built up SERPS was instead directed into a workplace or private scheme, which should be paying out in its own right. The entitlement did not evaporate. It changed address.
All contracting out stopped on 5 April 2016. GOV.UK adds that "After this, all National Insurance contributions are at the standard rate until you reach State Pension age."
GOV.UK states that "If you were contracted out, you will usually need more than 35 qualifying years to get the full rate of new State Pension."
That single sentence resolves a great deal of confusion. The commonly repeated rule of thumb, that 35 years buys the full amount, is written for records that began after April 2016. A career that included a contracted-out period is assessed differently, and the number of years needed can be higher. It is not a penalty applied after the fact. It reflects that lower National Insurance was paid at the time, or that the contributions went somewhere else.
There is no need to reconstruct this from memory. Three sources between them usually settle it:
If the contracted-out route sent contributions into a separate scheme, that scheme is a distinct asset, and one that people who have moved several times often lose sight of. Our guide to tracing lost UK pensions covers how to find schemes you have lost contact with.
Here is the reassuring part, and it is worth stating clearly before the complications.
Living overseas does not reduce the entitlement you have built up. Entitlement follows your National Insurance record, not your address. The SERPS you accrued between 1978 and 2002 sits on your record the same way whether you retire in Kent or Kuala Lumpur.
Three things do change, and they are the things a cross-border specialist looks at together rather than one at a time.
This is the single largest variable, and it has nothing to do with SERPS specifically. It depends on the country you live in.
GOV.UK applies a closed rule: the State Pension increases each year only if you live in the European Economic Area, Gibraltar, Switzerland, or a country with a UK social security agreement, and it names Canada and New Zealand as excluded even though agreements exist with both. Everything outside that list is frozen at the rate you were first paid.
For someone with a substantial Additional State Pension, that distinction compounds over a long retirement into a meaningful sum. Our guide to the frozen UK State Pension sets out the country position and the GOV.UK sources behind it, and the frozen State Pension calculator puts a figure on the gap over a retirement horizon you choose.
The State Pension, including any Additional State Pension, is taxable income. Which country has the right to tax it depends on the double taxation agreement between the UK and the country where you live. Some agreements give the taxing right to your country of residence, others preserve it for the UK, and a few split the treatment by pension type.
The State Pension is normally paid without tax deducted at source, so the question is less about deductions and more about where you declare it. Our guide to the NT tax code explains how treaty claims work for UK pension income more broadly.
If your forecast shows gaps, voluntary National Insurance may be able to fill them, and the rules for people abroad changed materially on 6 April 2026. Our guide to voluntary National Insurance contributions from abroad covers the current position, including the entry test that now applies.
Trying to work out what your UK State Pension is actually worth from abroad?
We connect qualifying expatriates with cross-border financial specialists who read the State Pension alongside the rest of a retirement plan. Request an introduction. We review every submission before any introduction is considered.
Everything above resolves into one document, and it is available from overseas.
The State Pension forecast at gov.uk/check-state-pension shows your qualifying years, any gaps, and the amount your record currently supports. It reflects the transitional calculation, so for anyone with pre-2016 years it already accounts for SERPS and for any contracted-out period. You do not need to work out the arithmetic yourself; you need to read the figure and understand what sits behind it.
Accessing the service requires a Government Gateway user ID. From overseas this occasionally proves awkward, and the International Pension Centre is the direct route when the online service will not co-operate. It is also the office that handles State Pension claims from abroad, rather than local offices.
Two further points are worth knowing:
The State Pension is rarely the largest line in an expatriate's retirement, but it is usually the most misunderstood, and it interacts with everything else.
A specialist who works across borders can read the forecast alongside the private and workplace pensions that contracting out may have fed, the uprating position of the country you intend to retire in, the treaty position that determines where the income is taxed, and the currency you will actually spend. Those questions have a habit of being answered separately, by different people, in a way that produces a plan that is correct in each part and incoherent as a whole.
Pharos Introductions is an introducer. We do not provide financial advice. What we do is understand your situation well enough to make one introduction to a regulated specialist equipped for it, and we review every submission before any introduction is considered.

SERPS is the State Earnings-Related Pension Scheme, which ran from 1978 to 2002. It paid an amount related to your earnings on top of the basic State Pension, for employees who were not contracted out. It was replaced by the State Second Pension from 2002 to 2016, and GOV.UK groups both under the heading Additional State Pension. SERPS no longer accrues, but the entitlement people built up under it was not cancelled. It either reaches you as Additional State Pension on top of the basic State Pension, or it is reflected inside your new State Pension starting amount, depending on when you reach State Pension age.
Nothing was taken away, but how it reaches you changed. GOV.UK states that the Additional State Pension is paid to a man born before 6 April 1951 or a woman born before 6 April 1953, which is the group who reached State Pension age before the new State Pension began on 6 April 2016. If you reach State Pension age on or after that date you get the new State Pension instead, and the years you spent building SERPS feed into the starting amount used to calculate it. You see one figure rather than a basic amount plus a separate SERPS payment, which is why people often assume theirs has vanished.
GOV.UK explains that under the State Pension rules before 2016, you or your workplace or private pension scheme could choose to contract out of the Additional State Pension, and that if you were contracted out some of your National Insurance contributions were either lower than for people who were not contracted out, or paid into another pension such as a workplace or private scheme. All contracting out stopped on 5 April 2016. The practical way to check is your State Pension forecast at gov.uk/check-state-pension, alongside old payslips showing a reduced National Insurance rate and any workplace scheme paperwork from before 2016.
It changes the arithmetic rather than removing an entitlement, because the National Insurance you paid was lower or was redirected into another pension that should pay out separately. GOV.UK states that if you were contracted out, you will usually need more than 35 qualifying years to get the full rate of new State Pension. That is why two people with the same number of years can see different forecasts. The pension built up in the contracted-out scheme is a real asset in its own right, and tracing it matters as much as reading the State Pension figure.
Yes. Entitlement follows your National Insurance record, not your address, so moving overseas does not reduce what you built up. Two things do change. Whether the payment rises each year depends on where you live, because GOV.UK only uprates the State Pension for people in the European Economic Area, Gibraltar, Switzerland or a country with a UK social security agreement, naming Canada and New Zealand as excluded. And which country has the right to tax the income depends on the double taxation agreement between the UK and your country of residence.
They are two successive schemes that GOV.UK puts under one label. SERPS ran from 1978 to 2002. The State Second Pension ran from 2002 to 2016 and widened the group who could build up entitlement, including people looking after children under 12 and claiming Child Benefit, and carers. GOV.UK notes that the Additional State Pension was also known as State Second Pension or SERPS, which is why the terms are used interchangeably in older paperwork.
