£1 Million Pound Mortgages: Monthly Repayments and Income Requirements

To get a large mortgage of £1 million, you would typically need a deposit of at least 10%, with some lenders requiring a deposit of 20%. You’re also likely to need an income of at least £200,000 to be approved.

At the time of writing (November 2025), the approximate monthly repayments on a £1 million mortgage are £5,846. This is based on current interest rates being around 5%, a typical mortgage term of 25 years, and opting for a capital repayment mortgage. Based on this, you would repay £1,753,770 over the mortgage term.

Traditionally, the domain of private banks, today, more and more high street lenders offer this level of borrowing. Keep scrolling for more information on what you can expect to pay, the income you’ll need, and other factors that affect your monthly repayments.

How much does a £1 million mortgage cost per month?

The amount you repay each month depends on your interest rate, mortgage term, and the type of mortgage you choose, such as a repayment or interest-only mortgage.

Securing a mortgage with a longer term typically results in smaller monthly repayments, but you’re likely to pay more over the mortgage term.

It’s a good idea to speak to one of the advisors we work with to understand your repayments better. They can assist you in obtaining more favourable terms and lower repayments than you might secure on your own when trying to get a mortgage.

How much must you earn to get a £1 million mortgage?

This depends on whether you choose a high-street lender or go private. The amount you can borrow is based on your salary. A conventional lender will usually base its affordability calculations on your salaried income (up to 4.5 times your income in most instances, going up to 6 times in rare cases).

Some will consider a percentage of your annual bonus (but rarely the whole bonus).

They’ll also factor in your fixed expenses, which can include everything from childcare to gym memberships, a process known as ‘stress-testing’.

A private lender can be much more flexible. They’ll likely consider your application on a case-by-case basis – looking at your salaried income on top of your yearly bonus and any other income streams you may have, such as rental income from a buy-to-let mortgage or your pension.

Some will even consider assets such as cars or luxury items as collateral against the loan.

How much deposit do you need for a £1 million mortgage?

Most lenders’ minimum deposit requirements range from 10% to 20% of the property value. So, you’ll likely need a deposit in this range to secure a £1 million mortgage.

Some high-street lenders impose income caps on higher-value loans. For example, many of them won’t lend beyond 75-80% loan-to-value above £1,000,000 – regardless of your income and other factors – which means you’d need a deposit of at least 10% to qualify for the finance you need, depending on the lender.

That said, it may be possible to find a £1 million mortgage with the same deposit requirements as a standard residential mortgage if your application is strong and minimal risk factors (such as bad credit) are present.

Under these circumstances, you could theoretically secure a mortgage with a smaller deposit of 5%, but it’s uncommon.

How to get a £1 million mortgage

Once you’ve found a property and completed the necessary calculations, your next step should be to find an experienced mortgage broker. This will increase your chances of approval and help you secure the best available terms.

Using our broker-matching service, you can speak to the right broker straightaway by simply enquiring online.

They’ll be able to help with:

• Deposit requirements: To secure a £1 million mortgage, you must save a minimum deposit of 10% to 20%. The exact amount required will depend on the property value. For example, for a £1,000,000 house, a 10% deposit would be £100,000. One simple way to save for this deposit is to open a savings account and put 10% to 15% of your monthly wage into the account.
• Reviewing and Optimising Your Credit Reports: It’s important to check your credit history before applying to ensure no bad credit issues exist and remove any inaccurate or outdated information that could hinder your chances of securing the mortgage you need.
• Gathering all the necessary paperwork for your application: Your broker will be able to guide you through the application process and all the typical documents required, proof of income, at least three months of bank statements, personal ID, proof of address, evidence of deposit, latest P60 form, etc.
• Determining Your Borrowing Capacity: Based on typical lender salary multiplier calculations, you might assume that £1 million is the maximum amount you can borrow for a mortgage. However, this may not be the case. A mortgage broker can assess your circumstances and eligibility for better deals from lenders, potentially allowing you to borrow more at better interest rates.
• Identify the Right Lender and Secure the Best Deal: Your mortgage broker can help you identify lenders offering the best interest rate terms. This can save you time and potentially money.
• Guiding you through the Mortgage Process: Getting a mortgage can be difficult, especially if it’s your first application. The right mortgage broker can help you with any issues you may face along the way, look after your interests and be a lifeline in case anything goes wrong.

Example monthly repayments for a £1 million mortgage

The table below shows how monthly payments on a £1 million mortgage can change depending on the rate and term.

Interest-only mortgages

Interest-only mortgages of this size do exist and are subject to similar restrictions that you’ll find on smaller interest-only mortgages.

You’re more likely to find interest-only mortgages offered by a private lender, though you shouldn’t completely rule out the high street.

As a general rule, you’ll need a slightly larger deposit. Most lenders will only accept loans up to 75% loan to value (LTV), though a small number will consider 80% or 85% in the right circumstances.

Remember: Some high street lenders impose LTV caps on high-value loans that supersede everything else. For example, regardless of other factors, they won’t lend above 75% of £1 million.

The main benefit of an interest-only mortgage is the lower monthly repayments.

Of course, this is evened out by the fact that the entire balance is due at the end of the mortgage term.

Your lender will want you to demonstrate a viable repayment strategy. Basically, they want to see that you’ll be able to pay off the large principal payment at the end of the loan.

The repayment amount for interest-only mortgages stays the same regardless of the loan term. For example, if the monthly repayment at a 6% interest rate is £5,000, it will remain the same whether you choose a 15-year or a 30-year term.

This is due to the principal amount not decreasing and being paid off in full until the end using a separate repayment vehicle.

For these tables, we assume the interest rate stays the same for the full length of the mortgage. Interest rates can change if you remortgage to a different rate or move from a fixed or discounted deal to the lender’s standard variable rate (SVR).

With the Bank of England base rate currently at 4% (November 2025) and the average mortgage rate between 5% and 6%, the repayment figures along these rows in the table above would be the most realistic at present. However, this can change as and when the base rate changes.

The benefits of using a private bank or specialist broker

While a broker can help you get a mortgage of this size, there are advantages to using a private bank instead.

1. A more flexible affordability criteria

Private banks have traditionally dominated the high-value mortgage space due to their ability to be more flexible in their acceptance criteria.

Private banks are often more willing to take risks and will take a more holistic look at your assets, not just your income. They’ll factor in shares, bonuses and various assets that a regular lender may not.

Some private lenders offer mortgages based on pension income.

This means that if you have unusual income streams, are self-employed, or hope to get a UK mortgage based on foreign income, they may be a better option than a high-street bank.

2. They usually offer more financing options

The flexibility of the private bank often extends to the kind of terms it offers. You’ll likely obtain an interest-only mortgage or a higher loan-to-value (LTV) ratio.

3. They often specialise in mortgages for £1 million and over

The premium you pay is reflected in the service you receive. Aside from giving you a more ‘tailored’ customer experience, niche private banks can be more efficient when pushing the deal through.

After all, it’s what they specialise in.

The benefits of using a conventional lender

Despite private banks’ willingness to provide mortgages of this amount, there are still reasons to use a conventional lender instead.

1. They’re easier to access

Many private banks require an introduction or impose other exclusive criteria you must fulfil before they even talk to you.

Not so with high street banks, who are much more open.

And just because they’re easier to get into doesn’t mean they’re less competent.

Some high-street lenders have their own specialist teams that only deal with large mortgage loans.

2. They’re often more straightforward

The ‘rigidity’ of the traditional lender can also be seen as its strength.

The mortgage application process is often easy to understand, and the acceptance criteria are quite transparent. This means that provided you complete your application thoroughly and fit the criteria, you’re likely to get approval.

3. There may be fewer fees to pay

Although the level of service might not be quite as high as that of a private bank, this can often save you money.

Buy-to-let mortgages

One-million-pound buy-to-let mortgages are out there, but the terms can be different.

Generally, lenders view buy-to-let as a higher risk and will expect you to put down a larger deposit. A 25% deposit is fairly standard, though some will go down to 15% if circumstances are right. A private bank might be more flexible.

Minimum income requirements can also be a factor, especially with high-street lenders.

Many mainstream lenders won’t offer a BTL mortgage to anyone earning less than £25k, though some will decide based on the projected rental yields. The general minimum mortgage payment is 125-130%.

Some private lenders will decide by factoring in additional income.

For example, getting a mortgage with bonus income factored in or capital from property, savings, or pensions may be possible.

Many buy-to-let mortgages are interest-only, so keep reading to see what an interest-only mortgage on £1,000,000 might look like.
