State pension warning as 450,000 Britons miss out on £575 triple lock boost

Thousands of Britons dream of retiring abroad for a better lifestyle, but the financial reality can be far harsher than expected.

Moving overseas could come with a hidden cost that many do not realise until it is too late.

British pensioners who choose to spend their retirement in countries such as Canada, Australia or New Zealand face losing more than £77,000 in state pension income over two decades, according to fresh analysis from wealth management firm Rathbones.

The loss is caused by the UK’s frozen pension policy, which locks payments at the level first received when someone moves to certain countries.

Unlike pensioners who stay in the UK, those living in these destinations do not receive annual increases, regardless of how long they have paid into the system.

Olly Cheng, a Financial Planning Divisional Lead at Rathbones, says: "What looks like a modest shortfall at first can quickly snowball into tens of thousands of pounds in lost income over retirement."

The triple lock mechanism guarantees that state pension payments rise annually by whichever is highest among inflation, average earnings growth, or 2.5 per cent.

However, this protection vanishes entirely for those relocating to nations without an uprating agreement with the UK.

Approximately 450,000 British pensioners residing overseas already find themselves caught by this frozen pension policy.

The wealth management firm's research reveals that someone who retired abroad during the 2016 tax year, when the new state pension was introduced, has already forfeited nearly £19,400 in payments.

This loss occurred simply because their pension remained static while UK-based retirees benefited from successive annual increases.

Bridging this income gap presents a considerable challenge for those planning overseas retirement.

The £77,585 shortfall over 20 years translates to roughly £3,880 each year, or approximately £320 monthly, that individuals must generate from alternative sources.

From April 2026, the full new flat-rate state pension stands at £12,547.60 annually.

Rathbones' calculations, based on the minimum 2.5 per cent yearly increase, demonstrate how rapidly the financial damage accumulates.

After a decade abroad, retirees could find themselves more than £18,600 worse off compared to those who stayed in Britain.

This figure climbs beyond £42,000 at the 15-year mark.

Should inflation or wage growth outpace the 2.5 per cent floor, the losses would prove even more substantial.

Building such a private financial buffer requires careful planning well before any relocation takes place.

Mr Cheng advises prospective expatriates to begin by verifying their National Insurance record to ensure they qualify for the maximum state pension, particularly when future increases will not apply.

He adds: "It's also vital to understand how much private income you'll need to replace any lost state pension, as well as factoring in local tax rules, healthcare costs and currency movements, all of which can materially affect how far your money stretches overseas."

The financial planning expert emphasises that certain decisions surrounding overseas retirement cannot be reversed once made.

Mr Cheng concludes: "Given the complexity and the irreversible nature of some decisions, taking professional financial advice before committing to a move can help avoid costly mistakes later on."
