Large Mortgage Loan
What is the biggest mortgage loan I can get? What is considered a large loan?
When it comes to high borrowing levels and large mortgage loans, there are a number of key factors, primarily around income, expenditure and available deposit – or equity, if we’re looking at remortgaging.
Often banks restrict their lending potential to maximum levels. At a higher Loan to Value of 95%, for example, the maximum mortgage could be around £500,000. At 90% Loan to Value, there’s a bit more deposit or equity, so the maximum borrowing could potentially increase up to £1 million.
Generally, borrowing potential works out between 4.5 times and 5.5 times the gross combined income of the mortgage applicants. But with large mortgage loans, we can also look at other avenues. If it’s a high net worth applicant, we would consider private banking mortgages, which don’t necessarily work to the same income multiples.
£1 million is considered a large loan, and some banks have premier lending teams for mortgages over £500,000. These offer a dedicated case handler and generally faster turnaround times for mortgage case assessment. That’s not available with every bank and building society – just a small handful – and each lender has very differing criteria.
We work to understand a client’s specific circumstances to ascertain the lending potential. We can show this to you on-screen for full understanding of the mortgage market at any given time, along with those multiples and the options available.
Are there specific products for large mortgages?
There can be slight differences. Fixed and tracker products are the most common and tend to target a certain loan size. Most products are available for mortgages of £50,000 up to £1 million.
We also see additional products in the larger loan space – from £1 million to £3 million depending on the different banks’ individual policy. The high street mortgage lenders with the largest market share tend to have more standardised products.
That means they have set products for each individual Loan to Value. Each bank has fixed and tracker rates with and without product fees. Within the private banking space there can still be standardisation of what the lender will offer, but we do find bespoke products in that space as well.
Are fixed or tracker rates better for larger mortgages?
As we speak today in December 2025, fixed versus tracker rates has been a hot topic for the last couple of years. We’ve now got a cooling base rate environment, which is expected to continue into 2026.
A fixed rate is good value now, but trackers are tied to the Bank of England base rate. If that continues to cool, the rate may reduce and become cheaper than current fixed rates.
With all mortgage cases, including larger loans, we compare the options against expectations for future interest rates as part of advising clients. We give you as much information as possible to help you decide.
Fixed rates almost always have penalties to exit early, and there are typically limits on how much you can overpay on the mortgage – generally around 10% of the loan per year.
Trackers often have no penalties at any time, offering a lot of flexibility.
With large loans, flexibility is naturally more appealing. It could allow you to pay off the mortgage with bonuses or other cash later down the line. You might also want the flexibility to move from a tracker to a fixed rate once the market has sufficiently cooled, or giving freedom to leave the tracker if the base rate looks likely to rise at some point in the future.
It’s all down to how an individual feels about the value of a tracker in a cooling interest rate environment as opposed to a fixed rate, where the benefit is knowing what your monthly payment is going to be at any time.
Can I split my loan between fixed and variable rates?
Yes, you can, but generally clients prefer to stick to one product type unless there is a specific plan for the future.

Who is eligible for a large mortgage loan? How is affordability assessed for high value mortgages?
Depending on the size, we may see some loans fall into high net worth and private banking territory. That allows us to take a pragmatic view on how your income can be used. It could be from many different sources or timelines that may not sit within standard high street mortgage lending.
In that scenario, affordability is entirely bespoke. Those private banks don’t have to abide by the same affordability rules as high street lending. On the high street, where we generally find the best valued mortgage rates, affordability is more standardised and generally allows you to borrow 4.5 to 5.5 times the gross combined income of the mortgage applicants.
In terms of income, £100,000 in combined or single gross earnings opens most doors, as well as additional interest-only features, which may appeal to higher earners.
Can bonuses, dividends or other irregular income be included?
Absolutely. With high street and private banking, lending policy differs massively. There will be policies around bonuses, dividends or other irregular income from restricted stock units, vested shares, commission, overtime, a second job, self-employment, contracting work or a car allowance – and that’s just a few.
Depending on the specific lending requirements and your income, we’ll determine which banks and building societies will offer the best results. There’s a completely different view across all those areas with each bank and building society.
Are there lenders who offer more flexible criteria for high earners?
Yes and no. Generally there’s greater borrowing potential for higher earners, and sometimes specific products, as we talked about earlier.
Interest-only mortgages are easier to achieve for higher earners, but the policy itself is not flexible. It’s not income that drives criteria to be flexible. It’s more that higher earners may naturally be able to achieve areas of criteria that others can’t.
Each lender has set criteria that won’t change regardless of the client and what they earn. It depends on the areas where banks want to be competitive or to differentiate, depending on their lending goals.
We often have clients who are quite well off and assume that they can access everything, all the time. But that’s not necessarily the case. That said, private banks aim to be flexible in how they review a client’s financial position, to take the most positive approach they can.
That can create more flexibility for higher earners, case by case, compared to the set criteria with the high street.
How can I get a large mortgage? Are they more difficult to get?
I wouldn’t say they’re more difficult to get. The processing is largely the same in the majority of cases, but there can be additional due diligence to ensure the income is sufficient across all sources. The key aspect in obtaining a large residential mortgage is always the level of income.
Can you get a large mortgage if you are self-employed or a limited company director?
Absolutely. In the wake of Covid, lenders actively restricted Loan to Income levels for the self-employed. Part of this was to do with the unknown impact of Covid itself on independent companies, but also due to government loans and grants that made assessing self-employed earnings more complex and difficult to underwrite.
But now the large majority of lenders are returning to normal and mortgages for the self-employed are much the same as for employed applicants, which is great.
How can a mortgage broker help here? Is there anything else we need to know?
We don’t charge any fees for mortgage cases, as we primarily work with larger loans to begin with. It helps us to be more exclusive with the service that we offer.
We’re on hand to assist clients to achieve their mortgage borrowing needs. We navigate the current economy and assess the future of mortgage rates.
We also proactively obtain lower rates as they become available for clients during the mortgage process, which banks don’t do directly. That’s an important distinction in a cooling interest rate environment.
Your adviser acts as the first point of contact for updates and progress from beginning to end, and will contact you for reviews at exactly the right time in the future.
