In most cases, you may need a household income of around £160,000–£200,000 to secure an £800,000 mortgage in the UK, based on typical lender income multiples of around 4 to 5 times income. However, this is only a starting point.
Some lenders may offer higher income multiples to suitable borrowers, particularly higher earners and applicants with strong affordability. How a lender assesses bonus, commission, contractor or self-employed income can also make a significant difference to the amount you can borrow.
At Oportfolio Mortgages, we assess affordability across high-street, specialist and private lenders. We recently helped an IT contractor earning around £150,000 secure an £835,000 mortgage, despite standard affordability calculations with many lenders falling short of the amount required.
This guide explains what salary you may need for an £800k mortgage, how lenders calculate affordability and why choosing the right lender can make a significant difference at this level of borrowing.
Quick answer: What salary do you need for an £800k mortgage?
As a rough guide, you may need a household income of approximately £177,778 at 4.5× income or £160,000 at 5× income to borrow £800,000.
However, some lenders can offer higher income multiples to suitable applicants. Your actual borrowing will depend on your income type, deposit, existing commitments, mortgage term, credit profile and the lender’s individual affordability calculation.
For example, Oportfolio recently arranged an £835,000 mortgage for an IT contractor earning around £150,000, equivalent to approximately 5.57× income, after identifying a lender that assessed his contractor income more favourably.

£800k Mortgage Salary Calculator (Typical UK Lender Multiples)
| Income multiple (rule-of-thumb) | Approx salary needed (single or joint household income) | ||||
|---|---|---|---|---|---|
| 4.0x | £200,000 | ||||
| 4.5x | £177,778 | ||||
| 5.0x | £160,000 | ||||
| 5.5x | £145,456 | ||||
| 6.0x | £133,333 |
These figures are useful illustrations rather than borrowing guarantees. A lender willing to offer a higher income multiple will still carry out a full affordability assessment.
For example, someone earning £150,000 would theoretically borrow around £675,000 at 4.5× income. At approximately 5.5× income, that figure rises to around £825,000.
That difference demonstrates why lender selection becomes increasingly important when you’re looking for a larger mortgage.
Not sure if an £800k mortgage is realistic for you?
Income multiples are only a starting point. Different lenders can produce very different borrowing figures depending on your income, deposit, outgoings and circumstances.
If you’re looking to borrow around £800,000, Oportfolio can assess your circumstances against a wide range of lender criteria and help you understand what may realistically be available.
Check My £800k Mortgage Affordability
Can you borrow 5 or 6 times your salary for an £800k mortgage?
Potentially. Although around 4 to 4.5 times household income is a useful starting point for estimating mortgage affordability, some lenders can offer 5 times income or more to suitable borrowers.
Access to higher income multiples can depend on factors such as:
- Your total income
- Your profession and employment type
- The stability of your income
- Your deposit and loan-to-value (LTV)
- Existing debts and monthly commitments
- Dependants and childcare costs
- Mortgage term and age
- Credit history
- The lender’s own affordability model
Higher multiples aren’t automatically available simply because someone earns a high salary. Two borrowers earning £150,000 could receive very different maximum mortgage amounts from different lenders.
At £800,000 borrowing, identifying lenders whose criteria suit your circumstances can therefore be just as important as the headline mortgage rate.
How much deposit do I need for an £800k mortgage?
An £800,000 mortgage refers to the amount you are borrowing, not the purchase price of the property. This means the deposit you need will depend on the property’s value and the resulting loan-to-value (LTV).
| Property price | Deposit | Mortgage | Approx. LTV |
|---|---|---|---|
| £850,000 | £50,000 | £800,000 | 95% |
| £900,000 | £100,000 | £800,000 | 89% |
| £1,000,000 | £200,000 | £800,000 | 80% |
| £1,200,000 | £400,000 | £800,000 | 67% |
A larger deposit and lower LTV can give you access to a wider range of mortgage products and potentially more competitive interest rates. It may also help with affordability, although lenders will still assess your income, expenditure and overall financial circumstances.
At this level of borrowing, lender appetite can vary considerably. Some lenders place limits on the maximum loan available at higher LTVs, while others may apply different affordability criteria depending on the size of the mortgage.
This means two applicants with the same income who both want to borrow £800,000 could have very different options depending on the value of the property and the deposit they have available.
Does a bigger deposit mean I can borrow more?
Not necessarily. A larger deposit reduces your LTV and can improve the range of mortgage products available to you, but it doesn’t automatically increase the amount a lender will consider affordable.
Your maximum borrowing will still depend on factors including your income, existing debts and commitments, dependants, mortgage term and the lender’s own affordability assessment.
For an £800,000 mortgage, income and affordability still need to support the full £800,000 loan, regardless of how large your deposit is.
How do lenders assess affordability for an £800k mortgage?
Income multiples are useful for estimating how much you might be able to borrow, but lenders do not make their decisions based on salary alone.
When assessing an £800,000 mortgage, a lender will look at both how much you earn and how much of that income they are willing to use, alongside your regular expenditure and financial commitments.
This is particularly important for higher earners whose income includes bonuses, commission, contracting income, dividends or income from their own business. Different lenders can assess the same income in very different ways.
Basic salary
For employed applicants, basic salary is generally the most straightforward form of income for a lender to assess.
However, earning a high salary does not automatically mean you will qualify for a particular income multiple. Lenders will also consider your expenditure, debts, dependants, mortgage term, deposit and overall affordability.
For example, an applicant earning £180,000 with significant monthly commitments could potentially have a lower borrowing capacity than someone earning £160,000 with very few outgoings.
Bonus, commission and overtime
If a significant proportion of your earnings comes from bonuses, commission or overtime, the lender you approach can make a considerable difference.
Some lenders may use all of your additional income where there is a strong and consistent track record, while others may only use a proportion of it or average your earnings over a particular period.
The evidence required can also vary. Depending on the lender and type of income, this could include recent payslips, a P60 or evidence of previous bonus or commission payments.
For someone looking to borrow £800,000, even a relatively small difference in the amount of additional income a lender accepts can have a significant impact on maximum borrowing.
Contractor income
Contractors can have particularly different affordability outcomes depending on the lender.
Some lenders may assess you using your accounts or declared income, while others may be prepared to calculate your income from your day rate or contract value.
Where a day rate is used, lenders can also differ in the number of working days or weeks they use to estimate annual income. This means two lenders could assess exactly the same contract and arrive at different income figures.
This can become particularly important when you need a larger mortgage, where the way your income is calculated could determine whether you reach the required borrowing amount.
Self-employed and company director income
Being self-employed does not necessarily prevent you from borrowing £800,000, but lender criteria can vary considerably.
Depending on how your business is structured and the lender’s criteria, affordability could be assessed using salary and dividends, net profit, your share of company profits or other acceptable business income.
This can be particularly important for company directors who deliberately leave profits within their business rather than drawing all available income personally.
As a result, a lender assessing only salary and dividends could produce a very different affordability figure from one able to consider the wider financial performance of the business.
Existing debts and monthly commitments
Lenders will also consider the money you already have going out each month.
This can include:
- Credit cards
- Personal loans and car finance
- Student loan repayments
- Childcare costs
- Maintenance payments
- Existing mortgages and other property commitments
- Dependants and regular household expenditure
This is why income multiples should only ever be treated as an indication. Two applicants earning exactly the same amount could qualify for very different mortgage sizes depending on their commitments.
Mortgage term and age
The term of the mortgage can also influence affordability.
A longer mortgage term can reduce the monthly repayment used within an affordability assessment, which may increase borrowing capacity in some circumstances. However, it also means paying interest over a longer period.
Your age can affect the maximum term available, particularly where the mortgage would continue beyond your expected retirement age. Some lenders may require evidence of how the mortgage will remain affordable later in the term.
Why lender selection matters for an £800k mortgage
At this level of borrowing, relatively small differences in lender criteria can translate into tens of thousands of pounds of additional or reduced borrowing capacity.
One lender might restrict the income multiple available to you, while another could offer a higher multiple. One might only use part of your bonus, while another could accept more of it. A contractor or company director could also have their income calculated differently from lender to lender.
This is why the question is not simply “How many times my salary can I borrow?” but also “Which lenders are best suited to the way I earn my income?”
For an £800,000 mortgage, understanding those differences can be crucial to establishing how much you can realistically borrow.
These differences in lender criteria can have a significant impact in practice, as the following recent Oportfolio case demonstrates.
Real example: £835,000 mortgage for an IT contractor earning £150,000
We recently helped a single applicant purchase a £1.65 million property with an £815,000 deposit, requiring an £835,000 mortgage.
The client’s circumstances
- Property price: £1,650,000
- Deposit: £815,000
- Mortgage required: £835,000
- Income: approximately £150,000
- Applicant: Single borrower
- Employment: IT contractor
- Contract rate: £600 per day, five days per week
The challenge
The client’s contract stated a daily rate rather than a fixed annual salary.
Contractor income calculations vary between lenders. Using a more restrictive calculation could have left the client short of the £835,000 required.
The client therefore needed a lender that would both assess his contractor income appropriately and consider the higher level of borrowing required.
How Oportfolio approached the case
We identified a lender willing to calculate the client’s contractor income using 50 working weeks per year and whose affordability assessment supported the higher level of borrowing required.
The client also had very low monthly outgoings, which helped support the affordability assessment.
The outcome
The lender was able to offer the full £835,000 mortgage, allowing the client to proceed with the £1.65 million purchase.
This case demonstrates why a headline salary multiple doesn’t always tell you how much you can borrow. The way individual lenders assess income and affordability can materially change the outcome, particularly for contractors and higher earners.
Mortgage approval is subject to individual circumstances and lender criteria. This example is illustrative of a previous Oportfolio case and does not guarantee the same outcome for another borrower.
How much does an £800k mortgage cost per month?
The monthly repayments on an £800,000 mortgage will depend primarily on your interest rate, mortgage term and whether you choose a repayment or interest-only mortgage.
For example, on an £800,000 capital repayment mortgage over 25 years, approximate monthly repayments would be:
| Interest Rate | Approx. monthly repayment |
|---|---|
| 4% | £4,223 |
| 5% | £4,677 |
| 6% | £5,154 |
These figures are illustrations rather than current mortgage quotations. The actual amount you pay will depend on the mortgage product and terms available to you.
How does the mortgage term affect repayments?
Choosing a longer mortgage term can significantly reduce the monthly repayment.
For example, at an illustrative interest rate of 5%:
| Mortgage Term | Approx. monthly repayment |
|---|---|
| 20 Years | £5,280 |
| 25 Years | £4,677 |
| 30 Years | £4,295 |
| 35 Years | £4,037 |
A longer term can make the monthly payments more manageable and may help with affordability in some circumstances. However, because you are repaying the mortgage over a longer period, you will generally pay more interest overall.
Your age and expected retirement age can also influence the maximum mortgage term available.
What about an interest-only £800k mortgage?
Some borrowers looking for larger mortgages may also consider an interest-only or part-and-part mortgage, subject to lender criteria and having an acceptable repayment strategy.
On an interest-only mortgage, your monthly payments cover the interest rather than reducing the original £800,000 balance.
For example, at an illustrative rate of 5%, the interest payment on an £800,000 mortgage would be approximately £3,333 per month.
However, the original £800,000 would still need to be repaid at the end of the mortgage term. Interest-only lending therefore has additional eligibility requirements, and lenders will normally want to understand how you intend to repay the capital.

Find out whether an £800k mortgage is realistic for you
Online salary calculations can give you a useful starting point, but an £800,000 mortgage is large enough that differences between lender affordability models can materially affect how much you can borrow.
This is particularly important if you:
- Earn bonus or commission
- Work as a contractor
- Are self-employed or a company director
- Have multiple sources of income
- Need a higher income multiple
- Have significant existing financial commitments
- Are buying a higher-value London property
Oportfolio Mortgages can assess your income, deposit and commitments against real lender criteria to establish which lenders are most likely to meet the borrowing you need.

FAQ: What Salary Do I Need for an £800k Mortgage in the UK?
Can I get an £800k mortgage on a £150k salary?
Potentially. An £800,000 mortgage on a £150,000 income is approximately 5.33 times income, so it would require a lender prepared to consider borrowing above a standard 4 or 4.5 times income calculation, alongside a successful affordability assessment.
Lender selection can therefore make a significant difference.
Oportfolio recently helped an IT contractor earning around £150,000 secure an £835,000 mortgage. The lender assessed his contractor income favourably, considered the higher level of borrowing required, and his low monthly outgoings helped support affordability.
This does not mean everyone earning £150,000 can borrow £800,000. Mortgage affordability is assessed individually and lender criteria vary.
Can I borrow £800k at 5 times my salary?
Yes, potentially. At exactly 5 times income, you would need a household income of £160,000 to reach an £800,000 mortgage.
Some lenders can consider 5 times income or more for suitable applicants, but this is not guaranteed. Eligibility can depend on your income, profession, deposit, existing commitments, mortgage term, credit history and the lender's affordability criteria.
A higher income multiple should therefore be treated as a possibility rather than an automatic entitlement.
How much deposit do I need for an £800k mortgage?
The deposit required depends on the purchase price of the property, because £800,000 refers to the amount you are borrowing rather than the property's value.
For example, if you bought a £1 million property with an £800,000 mortgage, you would have a £200,000 deposit and an 80% loan-to-value (LTV).
A larger deposit can reduce your LTV, potentially giving you access to a wider choice of lenders and mortgage products. However, your income and affordability must still support the £800,000 mortgage you want to borrow.
How much does an £800k mortgage cost per month?
The monthly repayment depends on your interest rate and mortgage term.
As an illustration, an £800,000 capital repayment mortgage over 25 years would cost approximately £4,223 per month at 4%, £4,677 at 5%, or £5,154 at 6%.
These figures are illustrations rather than current mortgage quotations. Your actual repayments will depend on the mortgage product, interest rate and term available to you.
You can use our Mortgage Repayment Calculator to compare different rates and terms.
Can I get an £800k mortgage as a contractor?
Yes. Contractors can potentially obtain an £800,000 mortgage, but the way your income is assessed can vary significantly between lenders.
Some lenders may assess your accounts or declared income, while others may calculate affordability using your day rate or contract value. Lenders can also use different assumptions about the number of working days or weeks in a year when annualising contractor income.
This means choosing a lender whose criteria suit your contract and working arrangements can materially affect how much you are able to borrow.
Can I get an £800k mortgage if I'm self-employed?
Yes. Self-employed applicants and company directors can potentially qualify for an £800,000 mortgage, provided their income and overall circumstances support the borrowing.
Different lenders can assess self-employed income differently. Depending on your business structure and the lender's criteria, affordability could be assessed using salary and dividends, net profit, your share of company profits or other acceptable business income. Some lenders may also consider retained profits in appropriate circumstances.
This means finding a lender whose approach reflects the way you earn your income can be particularly important for larger mortgages.
Can bonuses and commission be used towards an £800k mortgage?
Yes, many lenders can include bonus and commission income when assessing mortgage affordability, although the amount they will use varies.
A lender may use all or part of your additional income or calculate an average based on your previous earnings. The evidence required can also vary depending on the lender and how regularly the income is received.
For higher earners whose bonus or commission forms a significant part of their overall remuneration, these differences can have a substantial effect on maximum borrowing.
Can two people combine their salaries to get an £800k mortgage?
Yes. For a joint mortgage application, lenders can generally consider the incomes of both applicants when assessing how much you can borrow.
For example, two applicants earning £90,000 each would have a combined household income of £180,000. A simple 4.5 times income calculation would indicate borrowing of around £810,000.
However, the lender will also assess both applicants' debts, regular commitments, dependants, credit profiles and other affordability factors before deciding how much it is prepared to lend.
Are £800k mortgages harder to get?
Not necessarily, but borrowing £800,000 can involve additional considerations compared with a smaller mortgage.
Some lenders have different criteria for larger loans, and the income multiple, maximum LTV and affordability assessment available to you can vary. Your income structure can also become particularly important if you rely on bonuses, commission, contracting income or profits from your own business.
This makes it important to look beyond the headline interest rate and consider which lenders' affordability criteria are best suited to your circumstances.
Do I need a private bank for an £800k mortgage?
No. An £800,000 mortgage does not automatically require private banking.
Depending on your income, deposit and circumstances, an £800k mortgage may be available from high-street or specialist mortgage lenders.
Private banks can become relevant for some high-net-worth borrowers, particularly where circumstances involve substantial assets, complex income, unusual ownership structures or larger and more bespoke borrowing requirements.
The most appropriate route therefore depends on your overall circumstances rather than the mortgage amount alone.
