A practical guide to buying London property from overseas: ownership rules, the process, financing, stamp duty and other taxes, and how to buy well from abroad.

Buying property in London as an international buyer
There is nothing to stop a foreign national buying property in London. No permit, no residency test, no local partner. What stops overseas buyers buying well is distance, an unfamiliar process, and a market in which the best properties change hands before they are advertised. This guide covers what you need to know before you commit money, from the legal framework to the tax bill, written from the side of the person paying.
Can a foreign buyer own property in the UK?
Yes, outright. Freehold or leasehold, house or flat, in a personal name or through a structure, with the same legal title as a British citizen. Title is registered at HM Land Registry and guaranteed by the state.
The only gate is anti-money-laundering compliance. Every estate agent, solicitor and lender you deal with is obliged to verify who you are and where your money comes from, and they will each ask separately. Have certified identity documents, proof of address and a clear paper trail for the funds ready before you start. A buyer who cannot evidence source of funds promptly loses properties to buyers who can, and in a competitive situation the seller’s agent will not wait.
Since 2023, overseas companies owning UK property must also be registered on a public register of beneficial owners. This does not prevent corporate ownership, but it removes much of the anonymity that once made it attractive.
What is different about buying in London?
Three things surprise almost every international client.
First, there is no central listing system. Each agency holds only the properties instructed to it, and in prime central London a large proportion of sales are never advertised at all; in our own work 78% of purchases have been secured off-market. A buyer relying on the portals sees a partial and rather picked-over version of the market.
Second, the estate agent works for the seller. Nobody in the transaction represents the buyer unless the buyer appoints someone. In much of Europe and North America a buyer’s representative is normal; in London it is optional, and the absence is expensive.
Third, nothing is binding until exchange of contracts, which may be two or three months after your offer is accepted. Either side can withdraw without penalty until then. It follows that a buyer should not commit to flights, furniture or school places on the strength of an accepted offer.
How does the buying process work?
Prepare. Instruct a solicitor experienced in cross-border transactions, arrange finance or evidence of cash, and complete your compliance documents. If you intend to use a buying agent, this is the stage at which to appoint one.
Search. Define the brief precisely: purpose, holding period, budget including tax, must-haves. Then search the whole market, not the advertised part, and view in person or through someone whose judgement you trust. Photographs flatter London flats.
Offer. Offers are made through the seller’s agent and are not binding. Support the offer with evidence of comparable sales, and with your credentials as a buyer who will complete. In prime London a well-evidenced offer below asking succeeds far more often than a low offer with no argument behind it.
Due diligence. Your solicitor investigates title, the lease, searches and enquiries. A surveyor inspects the building. If you have a lender, they value it. This is where problems surface and where the price is sometimes renegotiated.
Exchange and completion. On exchange you pay a deposit, normally 10%, and the contract becomes binding with a fixed completion date. On completion the balance is paid, you receive the keys, and your solicitor pays the stamp duty and registers you as owner.
What ownership types will I encounter?
Houses are usually freehold: you own the building and the land indefinitely. Flats are usually leasehold: you buy a lease for a fixed term, often 99 to 999 years, and pay a service charge towards the running of the building. The length of the lease, the service charge and the quality of management affect value as much as the location does, and an international buyer should not sign for a flat without understanding all three. Some period conversions come with a share of the freehold, which gives the flat owners collective control.
How do international buyers finance a purchase?
Cash is simplest and strongest; a cash buyer with funds evidenced can exchange quickly and negotiate from that strength. If you prefer to borrow, the high-street banks are cautious with non-residents but private banks and specialist lenders are not, particularly where the buyer has assets to place. Expect a lower loan-to-value than a domestic borrower, perhaps 50 to 65% at the top of the market, and a requirement to bank with the lender. I came to property from banking and I still think of a purchase as one line on a wider balance sheet: how it is financed, in which currency, and through which entity should be decided with your bank and tax adviser together, before the offer.
What taxes does an overseas buyer pay?
Stamp duty land tax is due on purchase. The standard bands rise from 0% to 12% for a home; a buyer who owns another residential property anywhere in the world pays a 5% surcharge on top, and a non-UK resident pays a further 2%. On a £3m second home for a non-resident, the total bill approaches £500,000. It is payable within 14 days of completion.
Holding a residential property in a company attracts the annual tax on enveloped dwellings, charged in bands from a few thousand pounds to well over £280,000 a year, unless a relief applies; for a home you will use yourself, no relief applies, which is why most private buyers own personally.
Capital gains tax at 18% or 24% is charged on gains when a non-resident sells UK residential property, and inheritance tax at 40% applies to UK residential property above the nil-rate band of £325,000 regardless of where the owner lives or through what structure. Since April 2025 the UK’s treatment of foreign-domiciled individuals has moved to a residence-based test, which changes the planning for anyone intending to live here. Take advice before exchange from someone who knows both jurisdictions.
Rates and figures correct at the time of writing; confirm the current position before relying on them.
Where do international buyers buy?
Mayfair, Belgravia, Knightsbridge, Chelsea and Kensington remain the core, for their addresses, their liquidity and their resale to the next international buyer. St John’s Wood and Notting Hill draw families for schools and gardens. Marylebone, Fitzrovia and Covent Garden suit buyers who want to walk to work and to dinner. Which is right depends on purpose: a pied-à-terre used forty nights a year has different requirements from a family home or a rental investment.
How Arbitrage can help
We have acted only for buyers since 2006, and most of our clients are international: investors, family offices and private buyers from Italy, continental Europe, the Middle East and the United States. We search the whole market, view on your behalf, negotiate the price (our average is 12% below asking) and coordinate with your private bank, tax advisers and solicitors so that the purchase is structured correctly the first time. Our fee is a success fee on exchange, agreed in writing up front, with no retainer.
Frequently asked questions
Do I need to be in the UK to buy?
No. Viewings can be done on your behalf, documents can be signed abroad and witnessed, and funds can be transferred from any bank that satisfies compliance. Many of our clients complete without a single visit, though I would always recommend seeing the property once before exchange.
How long does a London purchase take?
Typically three to four months from accepted offer to completion, driven by legal due diligence and, if applicable, the lender. A cash buyer with a prepared solicitor can exchange in a few weeks when the property’s paperwork is in order.
Should I buy in my own name or through a company?
For a home you will use, personal ownership is almost always cheaper because of the annual tax on enveloped dwellings and the transparency rules. For rental investment or multiple units the answer may differ. Decide with a UK tax adviser before making an offer.
Can an overseas buyer get a UK mortgage?
Yes, principally from private banks and specialist lenders rather than the high street. Expect a lower loan-to-value, a requirement to evidence income and assets, and in some cases to place assets with the lender.
Is London property a good store of value for a foreign investor?
It has been a reliable one over the long term, in a stable legal system, with deep liquidity at the top end. It is not a short-term trade; buying, holding and selling costs are high, and the return comes from buying well and holding for years.
