London Real Estate for International HNW Buyers

London's prime central property market occupies a unique position in the world of international real estate. PCL — an area encompassing Mayfair, Belgravia, Knightsbridge, Chelsea, Kensington, Holland Park, and a handful of other neighbourhoods — has long functioned as a global safe-haven asset class in its own right, sought by UHNW individuals from the Middle East, Asia, Russia (historically), the Americas, and Europe for its combination of stability, cultural capital, legal certainty, and absolute scarcity of freehold land in a world city. But the tax and regulatory environment has changed materially since 2015, and international buyers must understand the current framework clearly before proceeding.

PCL Price Performance

Prime Central London house prices rose enormously in the decade to 2014, then entered an extended period of correction and stagnation driven by successive rounds of stamp duty increases, the introduction of the non-resident CGT charge, uncertainty around Brexit, and the departure of some price-setting buyer groups (Russian oligarchs, in particular, after 2022 sanctions). Knight Frank and Savills data show PCL values remaining approximately 15–20% below their 2014 peak in nominal terms as of early 2026, which in real (inflation-adjusted) terms represents a more significant decline.

The market has not collapsed — it has essentially flat-lined for a decade in nominal terms while the rest of the UK market has moved higher and back. The consequence is that PCL now looks relatively better value on an international comparison than it did at the 2014 peak, and some long-horizon buyers regard this as an entry opportunity.

The prime London market for houses and lateral apartments (£2 million–£10 million) has been somewhat more active than the super-prime (£10 million+) segment, where the buyer pool is thinner and the SDLT liability on a £15 million purchase (approximately 12–14%) becomes a formidable barrier.

Non-Resident Capital Gains Tax: Post-April 2019

Before April 2019, non-UK residents could sell UK residential property free of any capital gains tax. This changed fundamentally: from 6 April 2019, non-residents are subject to UK CGT on gains from all UK residential property disposals, not just properties acquired after that date (though for pre-April 2019 acquisitions, only the gain arising after that date is generally chargeable, with rebasing available).

The relevant CGT rates for UK residential property are:

• 18% for gains falling within the basic rate band
• 24% for gains above the basic rate band (as of 2024–25 onwards)

These rates apply to non-residents in the same way they apply to UK residents. There is no non-resident exemption.

Reporting obligation: Non-resident vendors must report and pay any CGT arising on UK residential property within 60 days of completion — even if the overall gain is covered by losses elsewhere or the taxpayer has no other UK tax obligations. Failure to report on time attracts automatic penalties. This is frequently overlooked by non-resident sellers using agents who are unfamiliar with the obligation.

The non-resident CGT charge applies to direct property ownership and also to indirect ownership through certain property-rich companies (see ATED section below for the corporate angle).

SDLT: The Non-Resident Surcharge

Stamp Duty Land Tax for residential property in England and Northern Ireland (Scotland has LBTT; Wales has LTT with their own rates) operates on a tiered basis. For a property over £1.5 million, the marginal rate is 12% on the excess above that threshold.

Non-resident surcharge: A 2% SDLT surcharge was introduced in April 2021, payable in addition to standard rates for buyers who are not UK residents at the time of purchase. A buyer who is non-UK resident purchasing a £3 million property will pay approximately 2% × £3 million = £60,000 in additional SDLT relative to a UK-resident buyer.

Higher rates for additional dwellings: The 5% SDLT surcharge on second homes (additional dwellings) — increased from 3% on 31 October 2024 — also applies to non-resident buyers who already own residential property anywhere in the world, in many cases. This can stack with the non-resident surcharge for a combined additional liability of 7% on the purchase price above the relevant thresholds.

A buyer of a £5 million PCL property who is non-resident and already owns property elsewhere will pay approximately:

• Standard SDLT on £5m: c. £511,250
• 5% additional-dwelling surcharge: £250,000
• 2% non-resident surcharge: £100,000
• Total: c. £861,250 — approximately 17.2% of the purchase price

This is a very significant transaction cost that materially affects the investment case and payback period.

Annual Tax on Enveloped Dwellings (ATED)

ATED applies to high-value UK residential properties held within companies, partnerships, and certain collective investment schemes. It was introduced in 2013 specifically to discourage the use of company "envelopes" to hold residential property (a structure historically used to avoid SDLT on share transfers rather than property transfers, and to plan around IHT).

ATED applies where:

• A residential property is worth over £500,000 (from April 2016)
• It is held in a company (UK or overseas), partnership with a corporate partner, or a collective investment scheme

The annual charge for the 2026–27 tax year ranges from:

• £4,600 per year (£500,001–£1 million)
• £9,450 per year (£1–£2 million)
• £32,100 per year (£2–£5 million)
• £74,200 per year (£5–£10 million)
• £148,900 per year (£10–£20 million)
• £298,500 per year (above £20 million)

These charges are substantial for high-value properties and compound significantly over time. Exemptions exist for properties let to unconnected third parties on a commercial basis (a property business exemption), development properties, and employee/shareholder occupation. However, the exemptions require the company to be a genuine property trading or letting business, not a personal use vehicle.

Company vs Personal Purchase: The Structural Decision

The decision to purchase in a company or personal name is now extremely complex for UK residential property:

Personal ownership advantages: No ATED; no corporation tax on rental income (personal higher rates apply, but no ATED drag); PPR relief available for primary residence; potentially simpler estate planning via spouse transfer.

Company ownership advantages: Some protection from personal liability (limited); potentially simpler multi-property structuring; easier to transfer via share sale (though SDLT anti-avoidance rules catch some of these scenarios).

Company ownership disadvantages: ATED liability for high-value properties; company purchase does not qualify for residential PPR relief; SDLT is still paid on the initial acquisition; Corporation tax on gains on disposal; no PPR relief on company gains; ATED-related CGT regime applies to non-exempt company-held properties.

For most individual HNW buyers of PCL residential property, personal ownership is now the more tax-efficient structure, absent specific commercial property business reasons. Any existing company-held residential property structure should be reviewed urgently with tax counsel.

Leasehold Reform: The Ongoing Structural Shift

The Leasehold and Freehold Reform Act 2024 made significant changes to the leasehold system in England and Wales, including reforms to lease extension rights, ground rent abolition for new leases, and the right to collective enfranchisement. This is directly relevant to PCL buyers, where leasehold property is extremely common (many mansion blocks and converted houses are long leasehold).

Key points: ground rents on new leases are banned at a peppercorn. Existing leases with high ground rents (the "fleecehold" scandal) retain their ground rent until extended under the new regime. Lease extension rights have been clarified and improved. The right to buy the freehold collectively (commonhold enfranchisement) has been strengthened.

Buyers of leasehold property should obtain a specialist leasehold lawyer's assessment of the specific lease terms, remaining term, ground rent, and extension costs before purchasing. A lease with 80 years or fewer remaining triggers a "marriage value" calculation on extension that materially increases the cost; always extend or acquire the freehold before lease term falls below 80 years if possible.
