If you have relocated to the UK from Hong Kong on the British National (Overseas) visa — commonly called the BNO visa — you may have found that mortgage lenders treat your application differently from applicants with settled status or a standard work visa. Some lenders are straightforwardly unfamiliar with the BNO route. Others have clear criteria.
This page explains how BNO visa holders are assessed for UK mortgages, which lenders offer the best terms, and what Mortgage Knight can do to help.
The British National (Overseas) visa was introduced in January 2021 following the national security law changes in Hong Kong. It allows BNO status holders — and their close family members — to live, work and study in the UK for up to 5 years, with a pathway to settlement (Indefinite Leave to Remain) after five years and British citizenship after six.
The BNO visa is a distinct immigration route with no direct equivalent in terms of how lenders categorise it. It is not a Skilled Worker visa, not a spouse visa, and not a student visa. Some lenders have updated their criteria to explicitly include it. Others apply their general foreign national policy. A small number have not yet developed specific guidance.
Because the BNO visa is a relatively recent route, lender criteria is less standardised than for other visa types.
apply their standard foreign national criteria to BNO holders assessing LTV based on residency duration and income in the same way as a Skilled Worker visa applicant. This gives access to up to 95% LTV in some cases.
some lenders cap at 75% LTV for BNO holders regardless of residency or income, treating them more conservatively as non-settled residents. In many cases, they may also require stronger affordability, a higher minimum income, or additional evidence of long-term UK residency before approving the application.
may decline or have no policy at all for BNO applicants. The right lender for a BNO visa mortgage depends on how long you have been in the UK, your income level, whether you are applying jointly or sole, and the deposit you have available. A whole-of-market broker who regularly handles BNO applications is the most effective route.
| Situation | Likely Maximum LTV |
|---|---|
| 5+ years UK residence | 95% |
| Permanent right to reside / ILR | 95% |
| 1+ year in UK, income ≥£50k (individual) / £75k (joint) | 95% |
| Any residency, income ≥£75k (individual) / £100k (joint) | 95% |
| Less than 1 year UK residency, income below threshold | 75% |
UK employment income is assessed in the same way as any other applicant — payslips, P60, employment contract. Most lenders require 3 months of payslips.
SA302 and tax year overviews. One to two years typically required. Where a business is newly established in the UK, some lenders will also consider overseas business income with the right documentation.
BNO holders working as IT or professional contractors through limited companies or umbrella arrangements can access the day rate mortgage route with appropriate lenders. The same day rate formula applies: day rate × 5 × 46 weeks = assessed income.
Some lenders will consider income earned overseas — for example, from a Hong Kong business or employment — alongside or instead of UK income. This requires currency conversion and is assessed by a limited pool of specialist lenders. A broker is essential for this route.
BNO holders who retain property in Hong Kong sometimes wish to include rental income in their UK mortgage affordability. This is considered by some specialist lenders on a case-by-case basis.
Overseas funds used as a deposit are generally accepted by UK mortgage lenders, but the process requires careful preparation. In most cases, the funds must be transferred into a UK bank account before the mortgage application completes. Lenders and solicitors will also require a clear source of funds paper trail showing where the money originated in Hong Kong, the transfer records, and confirmation that the funds have been received into the UK account.
Anti-Money Laundering checks are carried out by the conveyancer in every transaction, so having the correct documents prepared early is important. We advise clients on source of funds documentation at the start of the process to help avoid unnecessary delays during the legal stage.

Where a BNO visa holder applies jointly with a British citizen, settled status holder, or ILR applicant, lenders generally treat the case more favourably. The UK-based applicant strengthens the overall profile and reduces perceived risk.
This often improves affordability assessment and widens access to mainstream mortgage products compared to a sole BNO application.
In many cases, lenders may offer up to 95% LTV without strict income or residency conditions for the BNO applicant.
The deposit required for a BNO visa mortgage depends on your UK residency and income level. In stronger cases, some lenders may accept a 5% deposit, usually where the applicant has lived in the UK for at least one year and meets higher income requirements.
A 10% deposit is more widely accepted and gives access to a larger range of lenders. Where residency is limited or income is below the preferred threshold, lenders may require a 25% deposit.
Overseas deposit funds from Hong Kong are accepted by most lenders, provided the money is transferred into a UK bank account and supported by clear source-of-funds documentation.
Yes. Several UK lenders will consider BNO visa holders for residential mortgages. The terms available — including deposit required and maximum LTV — depend on your residency duration, income level and whether you are applying jointly.
From 5% where income and residency criteria are met. 25% is typically required for applicants with less than one year of UK residency and income below the lender’s threshold.
Yes. Overseas funds are accepted provided they are held in a UK bank account at application and a clear source-of-funds paper trail is provided.
Some specialist lenders will consider overseas income alongside or instead of UK income. This is a more complex case and requires a broker with specific experience in this area.
Yes. BNO holders working as IT or professional contractors can access day rate mortgage assessment with appropriate lenders — the same approach used for other foreign national contractors.
