Millionaire Migration 2025: Why Wealthy People Are Leaving the UK

For decades, the UK was a magnet for the world’s wealthy. From the leafy streets of Kensington to the rolling estates of the Cotswolds, high-net-worth individuals (HNWIs) flocked here for the stability, legal system, global connectivity, and, until recently, a favourable tax regime.

But 2025 tells a different story. This year, headlines are awash with talk of a “Wexit”: a record outflow of wealthy residents, with some reports suggesting 16,500 millionaires will leave the UK by the end of the year. Some critics such as the Financial News or The Guardian, argue that the numbers are inflated, but the underlying shift is hard to ignore.

So, is this the start of a wealth exodus? Or a media storm overblowing a small ripple in the high-value pond? More importantly, what does it mean for your wealth, and how should you respond?

What’s Driving the Trend?

1. The Changing Tax Landscape

Tax policy has always been a key driver of location decisions for HNWIs, and 2025 has been no exception.

• Non-Dom Overhaul: The long-discussed reforms to the UK’s non-dom regime are now a reality. For many international families, the ability to shelter foreign income from UK taxation was a major reason to settle here. With this advantage stripped back, some are reassessing their residency.
• Inheritance Tax (IHT) Freeze: According to Irwin Mitchell, the IHT threshold remains locked at £325,000-unchanged since 2009, while asset values have soared. HMRC collected a record £8.2 billion in IHT receipts in 2024/25, pulling more estates than ever into the net.
• Capital Gains and Dividend Tax Adjustments: While a wealth tax has been ruled out, higher CGT and dividend tax rates are firmly on the table for the Autumn Budget 2025.

These changes don’t just affect static wealth, they influence investment behaviour, succession planning, and cross-border structuring.

2. Cost of Living and Business Climate

While HNWIs are insulated from most cost-of-living concerns, the perception of economic headwinds matters. Sluggish growth forecasts (just 0.8% GDP growth expected in 2025, per the OECD) and increased operating costs for businesses can erode confidence, especially for entrepreneurs and family offices.

3. Global Competition for Wealth

The UK no longer has a monopoly on stability. Jurisdictions such as Dubai, Monaco, and Singapore are actively courting HNWIs with low- or zero-income tax, streamlined residency options, and robust financial infrastructure.

When rivals are offering zero tax on global income alongside world-class lifestyle benefits, even the most Anglophile investor may be tempted.

Is the Millionaire Migration Overblown?

The 16,500 figure comes from consultancy data Henley & Partners, 2025 that, while widely cited, has been criticised for relying on surveys and indirect modelling rather than hard migration statistics such as the Financial Times, 2025. HMRC exit data is notoriously patchy, and not every “departure” represents a total severance from the UK. Many HNWIs retain property, business interests, or even part-year residency.

However, even if the scale is debated, the sentiment shift is real. Private banks, law firms, and wealth managers are reporting increased client enquiries about emigration, tax domicile changes, and alternative investment jurisdictions.

What This Means for HNWIs Remaining in the UK

If you’re a high-net-worth individual who intends to remain UK-based, either for business, family, or personal reasons, this environment demands a proactive approach.

1. Review Your Tax Position

With the Autumn Budget looming, now is the time to assess:

• Estate Structuring: Leveraging trusts, family investment companies, and lifetime gifting to mitigate IHT.
• Asset Location: Considering whether certain investments should be held offshore or within tax-efficient wrappers.
• Pension Planning: Anticipating the April 2027 inclusion of pensions in taxable estates, already prompting £5 billion in early withdrawals in Q1 2025.

2. Explore Cross-Border Structuring

For globally mobile individuals, residency is no longer a fixed choice, it’s a strategic lever. Dual or multiple residencies, corporate structures in favourable jurisdictions, and international lending can protect flexibility.

3. Rethink Property Finance

If you hold or plan to acquire UK property:

• Lower Bank of England rates (now 4%) can present opportunities for refinancing at more favourable terms.
• For non-residents, structuring mortgages through specialist lenders can provide access to higher LTVs and more competitive rates than domestic banks typically offer.
• Bridging finance can be a powerful tool for high-value acquisitions in a shifting market.
