What counts as a large mortgage?
There's no single definition, but for many mainstream lenders anything above roughly £500,000–£1,000,000 falls outside their standard criteria — and the "best buy" tables stop being the best option. That's when specialist lenders and private banks become relevant: they underwrite each case individually and often price rates personally rather than off a shelf.
When income is complicated
High-street affordability calculators are built for simple salaries. If your income looks like any of these, the lender you approach matters more than the rate you're quoted:
- Income that's heavily weighted to bonus, commission or overtime.
- Self-employment, especially if profits have grown quickly or dipped.
- Company directors paid through a mix of salary and dividends.
- Several income streams — employment, rental income, investments, or family wealth.
How we approach larger loans
- We look across the whole market, including specialist lenders and private banks that don't appear on comparison sites.
- We present your full financial picture to a real underwriter, not just a calculator.
- We negotiate — on larger loans, rates are often individually priced and worth a conversation.
- Where it suits your plans, we'll explore interest-only structures with a clear repayment strategy.
What lenders will want to see
Expect a fuller picture than a standard application: income history and projections, assets, credit history, evidence of where your deposit came from, and — for interest-only — a credible plan for repaying the capital. None of it is scary with good preparation, and we'll tell you exactly what to gather before anything is submitted.
Discretion as standard
Larger loans often come with larger lives — business interests, property abroad, family arrangements. Everything you share with us stays between us; it's used only to find the right lender and nothing else.
Common questions
What's the difference between a large mortgage and a high-net-worth mortgage?
They overlap. 'Large mortgage' usually refers to the loan size; 'high-net-worth mortgage' is how lenders describe the specialist service for clients with significant income or assets — often with a more flexible, individually judged approach to lending. Either way, it's about finding a lender who understands your situation.
Can I borrow more if my income includes bonus or commission?
Often yes. Some lenders ignore variable income; others will take most or all of it if it's consistent. Knowing which lender is which is exactly what a broker is for.
Will a bigger loan always mean worse rates?
No — larger loans can actually attract better pricing, especially through private banks and specialist lenders, because rates are often priced individually. The key is presenting your circumstances to the right lender from the start.
