In simple terms, getting a large mortgage isn’t just about income, it’s about choosing the right lender.
If you’re unsure what you could borrow, we can usually give you a clear answer quickly based on real lender criteria.
What Is Considered a Large Mortgage in the UK?
A large mortgage in the UK typically refers to borrowing of:
- £500,000+ (entry level)
- £1m+ (high-value mortgages)
- £2m+ (complex / specialist lending)
Large mortgage loans often require:
- Higher income levels
- Larger deposits
- Access to specialist lenders
This is where working with a large mortgage broker becomes essential.
How to Get a Large Mortgage
If you’re looking to secure a large mortgage, lenders will assess:
- Your income (salary, bonus, dividends)
- Deposit size
- Credit profile
- Existing financial commitments
To improve your chances of approval:
- Work with a specialist broker
- Choose the right lender
- Structure your income correctly
- Reduce short-term liabilities
Getting a large mortgage is not just about income, it’s about strategy.
How Much Can You Borrow with a Large Mortgage?
Typical borrowing ranges:
- 4.5x–5.5x income (standard lenders)
- 5.5x–6x+ (specialist lenders)
The exact amount depends on your financial profile and the lender you choose.
Example
- Income: £150,000
- Standard lender: £675,000
- Specialist lender: £825,000
The difference is lender choice, not your income.
| Loan Size | Typical Income Needed | ||||
|---|---|---|---|---|---|
| £500,000 | £100 - £125K | ||||
| £750,000 | £150 - £190K | ||||
| £1,000,000 | £180 - £250K |
Which Lenders Offer Large Mortgages?
Large mortgage lenders include:
- High street banks
- Specialist lenders
- Private banks
Choosing the right lender is key to securing the best outcome.
Why lender choice can change how much you borrow
One of the biggest misconceptions is that all lenders offer similar borrowing amounts.
In reality:
- Some lenders cap borrowing at 4.5× income
- Others offer 5–6× income for the right applicant
- Some include bonus or variable income fully
- Others only include a small percentage
This means:
Two borrowers with identical incomes can receive very different results depending on the lender. For larger mortgages, choosing the right lender can make a significant difference to both approval chances and borrowing amount.
Can a mortgage broker help you borrow more?
In many cases, yes. Different lenders assess income in very different ways.
A broker can:
- Match you to lenders offering higher income multiples
- Use lenders that include bonus, dividends, or retained profit
- Structure your application to maximise affordability
This is especially important in London, where borrowing requirements are higher.
Why Use a Large Mortgage Broker?
Not all lenders are equipped to handle large mortgage loans.
A specialist large mortgage broker can:
- Access lenders who offer large loan mortgages
- Structure your application effectively
- Help you maximise borrowing potential
- Match you with the most suitable lender
The difference between lenders can often be £200k–£500k+ in borrowing.
How much deposit do you need?
Typical deposits:
- 10% → minimum entry point
- 15–25% → better rates + more lenders
- 25%+ → strongest position
Larger deposits:
- Improve rates
- Increase lender choice
- Reduce affordability pressure
Who can get a large mortgage?
Large mortgages are commonly secured by:
- High earners (finance, law, tech, medical)
- Self-employed / company directors
- Contractors and freelancers
- High-net-worth individuals
The key is not your job title, it’s how your income is assessed.
Why large mortgages are often declined
Most declines happen because:
- The wrong lender was chosen
- Income was assessed incorrectly
- The case didn’t fit automated criteria
Not because the borrower “couldn’t afford it”.
