Most UK expats in Portugal have worked for at least three or four employers before settling on the Algarve coast or the hills above the Tagus. Each of those jobs may have come with its own pension scheme — and over a 25-year career it is genuinely easy to lose track of one or two. The Pensions Policy Institute estimates there is over £31 billion sitting in lost UK pension pots. If even a small slice of that is yours, it is worth the afternoon it takes to track down.

This guide walks you through exactly how to trace lost UK pensions from Portugal, what to do once you find them, and the cross-border tax issues to think about before you touch a penny.

Why UK Expats Lose Pensions in the First Place

The most common reasons people lose track of UK pensions include changing jobs frequently in their twenties and thirties, moving house several times without updating pension providers, employers being taken over or merged into other companies, schemes being transferred to new administrators, and simply forgetting about small pots from short stints of employment.

For UK expats now living in Portugal, the problem is often worse. You may have moved abroad before updating addresses, lost paper statements during the move, or stopped receiving annual benefit statements entirely because the provider had no current address on file.

Step 1: Use the UK Government Pension Tracing Service

The Pension Tracing Service is a free, government-run database that holds contact details for over 200,000 UK workplace and personal pension schemes. It will not tell you whether you have a pension or how much it is worth — but it will give you the current contact details of the scheme administrator, which is the hard part.

You can access it online at gov.uk/find-pension-contact-details, by phone on 0800 731 0193 (from Portugal, dial +44 191 215 4491), or by post. To get the most accurate result, have the employer’s full name, any previous trading names, and the dates you worked there.

Step 2: Track Down Old Workplace Pensions

Once you have the scheme contact details, write to the administrator with your full name, date of birth, National Insurance number, dates of employment, and any policy or membership numbers you can find on old payslips or P60s.

Ask them to confirm whether you have a deferred benefit in the scheme, the current transfer value or projected income at retirement, and the scheme rules around accessing benefits from abroad. Expect a response in four to eight weeks. Some schemes are slow, particularly if your employer has been through a merger or insolvency.

Step 3: Check for Personal Pensions and Old SIPPs

Personal pensions and SIPPs are harder to trace because they are not on the Pension Tracing Service in the same way. Start by checking old bank statements for direct debits to pension providers, your credit file via Experian or Equifax for any historic pension accounts, and emails for any annual statements you may have ignored at the time.

If you remember the provider but have lost the policy number, contact them directly with your personal details and any approximate dates. Major providers like Aviva, Standard Life, Scottish Widows, and Phoenix Group have dedicated tracing teams.

Step 4: Reclaim Your UK State Pension Record

Many UK expats are surprised to find out they have State Pension entitlement they had forgotten about. You can get a State Pension forecast at gov.uk/check-state-pension, which shows your qualifying years and projected weekly payment. If you have gaps, you may be able to make voluntary Class 2 or Class 3 National Insurance contributions to boost your eventual payout — often one of the best-value financial moves a UK expat in Portugal can make.

Step 5: Consider Consolidation — But Carefully

Once you have found everything, the temptation is to consolidate it all into one pot. Sometimes that is the right move. Other times it is a disaster. Defined benefit pensions, in particular, almost always carry valuable guarantees that you give up the moment you transfer them out. Anything over £30,000 in DB benefits also requires regulated advice in the UK before transfer.

For UK expats specifically, the cross-border angle matters. The Lifetime Allowance has been abolished, but the new Lump Sum Allowance and Lump Sum and Death Benefit Allowance still cap what can be taken tax-free. How Portugal treats your pension income — and whether you still have NHR status — can dramatically change the maths.

The Portugal Tax Angle You Cannot Ignore

If you trace a lost pension and decide to draw from it while living in Portugal, the income is generally taxable in Portugal under the UK-Portugal Double Taxation Treaty. For those still inside their NHR 2.0 or original NHR window, the treatment is favourable. For everyone else, foreign pension income is taxed at marginal Portuguese rates, which can reach 48%.

Crucially, taking a UK tax-free lump sum is not automatically tax-free in Portugal. The Portuguese tax authority treats it as pension income unless very specific conditions are met. Always model the tax before you take the cash.

What to Do Next

Tracing lost UK pensions is one of those jobs that sits on the to-do list for years and then takes an afternoon when you finally tackle it. Start with the Pension Tracing Service, work through old employments in order, and request statements from every scheme you find.

Once you have the full picture, get advice before you do anything irreversible.
