There is no fixed salary or deposit rule for a high-value mortgage. See how affordability, income structure and loan-to-value affect what you may be able to borrow.
Sep 22, 2026
There is no fixed income or deposit requirement for a high-value mortgage in the UK. The amount you can borrow depends on the lender’s affordability assessment, the size of the loan, your deposit, your regular commitments, the property and how your income is earned.
This is why two applicants with the same salary and deposit can receive different decisions. One may have straightforward PAYE income and few commitments. The other may rely on bonuses, company profits or foreign income and have school fees, car finance or other mortgages.
The right question is not simply, “How much do I earn?” It is whether your complete application fits a lender’s large-loan criteria.
There is no universal salary or deposit rule for a high-value mortgage. As a mathematical example, a £1 million mortgage would require household income of about £222,222 at 4.5 times income, £200,000 at 5 times income or £181,818 at 5.5 times income. These figures are not lending promises because affordability checks still apply. Deposit requirements also vary by lender, loan size, property and mortgage structure. A larger deposit can improve your options, but it does not guarantee approval.
There is no official UK threshold. The term is often used for mortgages of £1 million or more, although individual lenders apply their own large-loan bands and underwriting limits.
A £750,000 application could receive additional checks with one lender while another treats it as a standard residential mortgage. The loan also needs to be judged against the property value. A £1 million mortgage on a £1.25 million property is 80% loan-to-value, while the same loan on a £2 million property is 50% loan-to-value.

Lenders may use an income multiple to produce an initial borrowing figure. The final decision is then shaped by a full affordability assessment.
For a £1 million mortgage, the basic calculations are:
These are mathematical illustrations, not examples of guaranteed borrowing. A lender may offer less, even where the income appears sufficient.
Your maximum mortgage may be affected by:
A longer term may reduce the monthly repayment used in the calculation, but it can also increase the total interest paid over the life of the mortgage.
You can use the MBNM mortgage calculator for an initial estimate. A calculator cannot apply every lender’s large-loan limits or individual affordability rules.
The way you earn can be just as important as the amount you earn. Depending on the lender, assessable income may include:
A lender may use all, part or none of variable income. The decision can depend on how long you have received it, how frequently it is paid and whether it appears sustainable. Payslips, P60s and employment contracts may be needed to show a consistent record.
One lender may assess salary and dividends only. Another may consider salary plus a share of company profit, subject to its criteria and evidence from the company accounts. Retained profits can strengthen some applications but are not accepted in the same way by every lender.
Lenders may review accounts, SA302 forms, HMRC tax year overviews, business bank statements and current contracts. The figures used can differ depending on whether you are a sole trader, partner, limited company director or contractor.

Some lenders consider income paid in another currency, but the choice may be smaller. A lender may reduce the income used in its calculation to allow for exchange-rate movements.
There is no universal minimum deposit. The required amount depends on the lender, mortgage size, property value, affordability, property type and whether the mortgage is repayment, interest-only or part repayment.
For a £1.25 million property, the figures would be:
These examples explain loan-to-value only. They do not show that a lender will accept the loan.
A larger deposit reduces the lender’s exposure if the property value falls. It may increase your choice of lenders, improve the products available and make a larger loan easier to place.
However, a bigger deposit cannot fix an application that fails affordability checks. It also cannot make an unacceptable property, repayment plan or credit history acceptable.
Yes. Some lenders reduce their maximum loan-to-value when a mortgage exceeds a particular amount. A lender might therefore accept a higher loan-to-value on a smaller mortgage but require more equity for a larger loan.
Large-loan limits can also vary by property type and location. A standard home may fit one lender’s criteria while a listed property, large country home, mixed-use building or short-lease flat does not.
You should be ready to show where the deposit came from. Acceptable sources may include:
The lender and solicitor may request bank statements, investment statements, sale documents or a gifted deposit declaration. Unexplained transfers can delay the application.
Income and deposit are not separate tests. The lender considers how the complete application fits together.
A larger deposit can reduce the loan-to-value, but the mortgage must still be affordable. A high income can support the required loan, but the property and deposit must still fit the lender’s rules.
These are simplified illustrations, not real MBNM client cases or lending decisions.
A couple want a £1 million mortgage on a £1.25 million property. They have a £250,000 deposit, producing an 80% loan-to-value. Their combined gross income is £220,000.
The loan is about 4.55 times their income. That may appear possible at first, but the lender will still assess childcare, loans, credit cards, the mortgage term and other regular commitments.
A company director has a salary, dividends and profits retained in the business. A lender using salary and dividends only may calculate that the required mortgage is unaffordable. Another lender may consider the director’s share of company profit, subject to its criteria and the company accounts.
The answer is not to exaggerate income. It is to use accurate evidence and identify a lender whose assessment method fits the applicant’s circumstances.
An applicant has a 40% deposit but receives a large part of their income through annual bonuses. The low loan-to-value may help, but the lender will still want evidence showing whether the bonus is regular and likely to continue.
In each example, the income multiple is only one part of the decision.
Income and deposit are central to the application, but they are not the only requirements.
Lenders may review missed payments, defaults, County Court Judgments, credit utilisation, recent borrowing and the conduct of existing mortgages. A high income does not cancel out credit problems.
The property is the lender’s security. Non-standard construction, listed status, large plots, annexes, short leases, extensive renovation work and mixed use can reduce the number of suitable lenders.
The proposed term affects both affordability and the total interest paid. Lenders may also consider your age at the end of the term and whether income is expected to change before the mortgage is repaid.
Interest-only and part repayment options may be available, but the lender will usually require a credible way to repay the remaining balance. This might include investments, another property, pension assets or a planned sale and downsize, where acceptable.
A high-value application may require:
Getting the documents ready before applying can reduce avoidable questions and delays.
False. Affordability, credit history, the deposit, the property and the evidence supplied can still prevent approval.
False. There is no universal percentage. The required deposit depends on the lender, loan size and complete application.
False. High street and specialist lenders can also provide mortgages of £1 million or more, subject to their criteria.
Not automatically. Assets may strengthen an application or support a private banking route, but many lenders still need to show that the mortgage is affordable.
False. Product fees, valuation fees, legal costs, early repayment charges and other conditions can change the total cost.

As a simple calculation, a £1 million mortgage requires about £222,222 of household income at 4.5 times income, £200,000 at 5 times income or £181,818 at 5.5 times income. Your actual borrowing depends on affordability and lender criteria.
There is no single answer because the deposit depends on the property price and permitted loan-to-value. A £1 million mortgage on a £1.25 million property is 80% loan-to-value and requires a £250,000 deposit. The lender must still approve the borrower and property.
Potentially, but lender choice may be limited and some lenders reduce their maximum loan-to-value for larger loans. Approval depends on affordability, the property, credit history and the lender’s maximum loan size.
Potentially. The lender may use all or part of the income depending on its history, frequency and likelihood of continuing.
Yes. You will need evidence showing your income and whether it is sustainable. Different lenders can use different figures from the same accounts.
No. A high-value mortgage refers to the size of the loan. Under the FCA definition, a high net worth mortgage customer has annual net income of at least £300,000, net assets of at least £3 million, or obligations guaranteed by someone meeting one of those thresholds.
No. The right route could be a high street lender, specialist lender or private bank. The best fit depends on the loan, income, assets, property and required structure.

If you have multiple income streams, recent changes to your accounts, or you have been told your income is “too complex”, you can still get a mortgage. The key is how your income is evidenced, explained, and presented to the right lender. In this guide, we break down how lenders assess complex income, what documents you will need, when cases get declined, and how we helped a self-employed buyer secure a full mortgage offer in time to keep their property chain together.

If you are moving home, you may be able to take your mortgage with you, but it is not guaranteed. Most UK mortgages are portable, however you still have to reapply, meet current lending rules, and get the lender’s approval. Porting keeps your existing rate, but extra borrowing usually goes on a new deal and early repayment charges can still apply in some cases. Before deciding, compare porting against switching mortgages, as changing lender can sometimes be cheaper and simpler long term.
