Two layers of complexity, one transaction
Buying UK property as a foreign national is already specialist territory. Doing it through a UK limited company adds a second layer of underwriting complexity — different lender criteria, different income assessment, and a much shorter list of willing lenders. That combination trips up a lot of buyers, and it trips up a lot of brokers too. What follows answers the questions that come up most often, in plain terms.
Can a foreign national actually get a UK mortgage through a limited company?
Yes — but the pool of lenders is narrow. Most high-street banks decline both foreign nationals and limited-company borrowers on standard products, so the overlap is handled almost exclusively by specialist and challenger lenders. The good news is that a growing number of those lenders will assess the application on the property's rental income, the company's structure, and the director's background, rather than UK employment or a UK credit history.
Does the company need to be a Special Purpose Vehicle (SPV), or can it be a trading company?
Almost every lender in this space requires the company to be a Special Purpose Vehicle — a company set up solely to hold property, with an SIC code of 68100 or 68209. A trading company that also holds property as a sideline will be declined by the majority of portfolio lenders, because the trading activity creates liability risk that sits above the mortgage. If your trading company already exists, the cleanest route is to incorporate a separate SPV and transfer — or buy — the property through that entity instead.
Which SIC codes do lenders accept?
The two codes lenders universally accept are 68100 (buying and selling of own real estate) and 68209 (other letting and operating of own or leased real estate). A small number of lenders will also accept 68201 (renting and operating of Housing Association real estate), but this is less common. Register your company with the correct code at Companies House before you approach any lender — some will decline the moment they see a mismatched code, regardless of the business's actual purpose.
How do lenders assess a foreign national director's background?
Lenders look at three things: residency status, credit profile, and the strength of the connection to the UK. You don't need indefinite leave to remain or a UK passport, but you do need a verifiable address history, a reason for the UK investment (family, employment, business interest), and — critically — a satisfactory credit search. Because many foreign nationals have no UK credit footprint, some lenders will accept an international credit report from services such as Nova Credit or a letter from your home-country bank. Others will simply decline if there is no UK credit file at all, which is why lender selection matters enormously before you apply.
What deposit is required, and how does it compare to a standard BTL?
Most lenders in this segment require a minimum of 25% deposit, though some push to 30–35% for foreign nationals without UK residency. That is broadly in line with standard limited-company buy-to-let, but the top end of the range is higher. Lenders see foreign nationality as an additional risk factor — primarily because enforcing a personal guarantee against an overseas individual is legally complex — so they offset that with a lower loan-to-value ceiling. Budget for 30% as a working assumption and treat 25% as the best-case outcome.
Does the company need a UK bank account before applying for a mortgage?
Most lenders require rental income to be paid into a UK business bank account held in the company's name. Opening that account can be surprisingly difficult for a newly incorporated SPV with foreign-national directors, as challenger banks (Starling Business, Tide, Monzo Business) tend to be more accessible than traditional high-street banks in this scenario. Start the bank account application as early as possible — ideally at the same time as incorporation — because delays here can stall the mortgage process by weeks.
Will the lender require a personal guarantee from the foreign-national director?
Yes, almost universally. Limited-company buy-to-let mortgages are advanced to the company, but lenders require one or more directors to provide a personal guarantee (PG) — meaning you are personally liable if the company defaults. For foreign nationals, some lenders add a UK-resident co-guarantor requirement, or insist on enhanced legal indemnity insurance, precisely because cross-border enforcement of a PG is complicated. Understand the PG terms in full before you proceed; it is not a formality.
How is rental income assessed for stress-testing purposes?
The lender will apply an interest coverage ratio (ICR) test — typically requiring the property's projected rental income to cover 125–145% of the mortgage interest payment at a stressed rate (often 5.5–6.5%, regardless of the actual product rate). For higher-rate taxpayers and foreign nationals, some lenders apply the more conservative 145% threshold. Make sure your rental income estimate is based on a formal RICS valuation or a lettings agent's written market appraisal — lenders will not accept informal estimates.
Are there extra tax or compliance considerations for foreign nationals buying through a UK company?
Several. The Annual Tax on Enveloped Dwellings (ATED) applies if the property is valued above £500,000 and is held in a company — annual returns are mandatory even if the charge is nil. Foreign nationals are also subject to Stamp Duty Land Tax (SDLT) at the corporate rate plus a 2% non-resident surcharge, on top of the standard 3% additional-dwellings surcharge. Rental income from the SPV is subject to UK Corporation Tax, and dividend distributions to a foreign-national director may trigger withholding tax obligations depending on the relevant double-taxation treaty. Take independent tax advice before completing — the mortgage is only one piece of the structure.
Which lenders are most likely to approve this type of case?
Specialist buy-to-let lenders — including names such as Precise Mortgages, Foundation Home Loans, Fleet Mortgages, and certain private banks — regularly handle foreign-national, limited-company applications, though criteria change frequently and are assessed case by case. High-street lenders (the major clearing banks) generally do not lend in this configuration on standard products. Approaching lenders direct is rarely productive; the criteria for foreign-national, SPV-structure cases are almost never published in full, and a declined application leaves a credit footprint. A whole-of-market specialist broker with live lender relationships is the most efficient route. Agnes Mortgage specialises in expat and foreign-national mortgages, including limited-company structures, and advises in English, German, Spanish, and Hungarian.
Still unsure where to start?
The question most people circle back to is this: which lender is actually willing to consider my specific combination of nationality, residency status, and company structure? That answer changes by lender, by month, and by the finer details of your application. Before you register a company, open a bank account, or instruct a solicitor, spend thirty minutes with a broker who places these cases regularly — it will save you weeks of misdirected effort.
Key takeaways
- Foreign nationals can get a UK limited-company mortgage, but the lender pool is small and almost entirely specialist.
- Your company must be an SPV with SIC code 68100 or 68209 — trading companies are routinely declined.
- Budget for a 30% deposit as a working assumption; 25% is achievable but not guaranteed.
- A personal guarantee from the director is standard; for foreign nationals, some lenders require a UK-resident co-guarantor.
- SDLT surcharges, ATED, and Corporation Tax all apply — get tax advice before you exchange contracts.
- Lender criteria in this niche are not publicly documented in full; a whole-of-market specialist broker is the most direct path to approval.

Frequently asked questions
Can a foreign national get a UK buy-to-let mortgage through a limited company?
Yes, but the choice of lenders is limited almost entirely to specialist and challenger lenders — high-street banks rarely accommodate this combination. Lenders typically require a 25–35% deposit, a UK-registered SPV with the correct SIC code, and a personal guarantee from the director.
What SIC code does a company need to get a buy-to-let mortgage in the UK?
The two SIC codes accepted by nearly all buy-to-let mortgage lenders are 68100 (buying and selling of own real estate) and 68209 (other letting and operating of own or leased real estate). Registering the correct code at Companies House before applying is essential, as a mismatched code can result in an immediate decline.
Do foreign nationals need a UK credit history to get a limited company mortgage?
Not always, but the absence of a UK credit footprint narrows the lender pool significantly. Some specialist lenders will accept an international credit report or a bank reference letter from the applicant's home country as an alternative; others will decline with no UK credit file at all.
How much deposit does a foreign national need for a UK limited company buy-to-let?
Most lenders in this segment require between 25% and 35% of the property value. A 30% deposit is a sensible working assumption, with 25% achievable in stronger cases where the applicant has UK ties, a clean credit profile, and strong rental coverage.
Is a personal guarantee required for a limited company buy-to-let mortgage?
Yes — virtually all limited-company buy-to-let lenders require a personal guarantee from the company director or directors. For foreign nationals without UK residency, some lenders also require a UK-resident co-guarantor or additional legal indemnity insurance due to the complexity of cross-border enforcement.
