Large Mortgage Loan

Mortgages over £1m, arranged with the private banks and specialist lenders that sit beyond high-street product caps.

Once a mortgage requirement runs past around £1 million, the picture changes. Many mainstream lenders apply product caps at this level, and high-value properties carry different risk considerations for a lender, so the field of available options narrows. A large mortgage loan is borrowing arranged at this scale — for a substantial residential property, or a larger investment — placed with the private banks and specialist lenders equipped to handle it.

Propertyze arranges large mortgage loans for clients in London and across the UK, structuring each case around the borrower's full financial position. At this level, the structuring and presentation of the case is often as important as the headline figures, and that is where specialist broking earns its place.

Key facts

  • What it is: mortgage lending at larger loan sizes — commonly understood to start from around £1 million — for residential or investment property.
  • Who it suits: high earners and high net worth individuals, business owners, self-employed borrowers and investors purchasing or refinancing higher-value property.
  • Why options narrow: many high-street lenders cap individual products at around £1m (some to roughly £1.5m); above that, lending moves to private banks and specialist lenders.
  • Loan-to-value: depends on whether the property is residential or an investment, and on the lender and case. For residential lending, available LTV can be higher than for investment lending, which is typically more conservative. Specific limits are always lender- and case-dependent.
  • Underwriting: at this scale, lenders frequently assess your overall wealth — income, savings, investments and other assets — rather than a single income figure.
  • Regulation: a loan secured on a home is FCA-regulated. Your home may be repossessed if you do not keep up repayments on a mortgage secured on it. Lending for investment or business purposes may be unregulated.

How large mortgage lending works

Mechanically, a large mortgage is still a loan secured against property and repaid over a term. The difference is on the lender's side. A high-value property is, by definition, affordable to fewer buyers, which affects how readily a lender judges it could be sold if it ever needed to be. Combined with product caps, this is why much large-loan lending sits with private banks and specialist lenders rather than the high street.

These lenders tend to underwrite on the whole picture. If you are borrowing at this level, you will often hold other assets — savings, investments, pensions, business interests — and a lender able to take that wider position into account can get more comfortable with the case. That broader view can, in turn, influence the terms available. None of it is automatic: the outcome depends on the lender, the property and how the case stacks up.

The regulatory reality

Whether a large mortgage is regulated depends on its purpose and security. Lending secured on a property you or an immediate family member occupy is a regulated mortgage contract and carries full FCA consumer protections. Lending for investment, portfolio or business purposes — including much buy-to-let — may fall outside FCA regulation.

Where a case spans both regulated residential and unregulated investment borrowing, we will make clear which is which and what protections apply to each before you commit. Propertyze conducts both regulated and unregulated business, and not all products we can arrange are regulated by the FCA.

Which lenders, and why a specialist broker helps

Above the high street's product caps, large-loan lending is concentrated among private banks and specialist lenders, many of whom do not publish standard terms and prefer to engage through brokers. Knowing which lender suits a given case — and how to present it — is the difference between a smooth placement and a stalled one.

A large mortgage is rarely a simple transaction, so structuring matters. The way your overall position is presented to a lender affects the products and rates you are offered. Working across a panel of more than 135 lenders, Propertyze can match your case to the right lender and frame it to put your full financial position forward — sometimes opening solutions a borrower would not have known were available, for example by giving a lender visibility of wider assets that strengthen the case.

Common complications we handle

  • Self-employed and limited company directors — income drawn from salary, dividends, retained profits or ongoing company profitability, evidenced through accounts rather than payslips.
  • Investment and portfolio income — rental and other income used to support borrowing.
  • Higher-value or unusual security — properties that exceed mainstream product caps or that lenders treat cautiously.
  • Credit history considerations — a genuine one-off blip can often be discussed with an underwriter on its merits; more serious adverse credit is harder and depends on the detail.
  • Wealth-backed structuring — bringing wider assets into a case to support the lending where a lender is willing to consider it.

The process

  1. Initial conversation — we discuss the property, the loan required and an overview of your income and assets.
  2. Case assessment — we identify suitable lenders and the most appropriate structure.
  3. Packaging and submission — we present your overall position to the chosen lender(s).
  4. Negotiation — we work with the lender on terms, rate and structure.
  5. Offer and completion — we manage the case through underwriting, valuation and legals to completion.

Frequently asked questions

What is the largest mortgage I can get? There is no fixed ceiling — large loans can run well into the millions and beyond. What is available to you depends on the property, your overall financial position and the lender. Most high-street products cap at around £1m–£1.5m, so larger loans move to private banks and specialist lenders.

Who is eligible? Eligibility is case-specific. Borrowers at this level often hold other assets — cash, investments, pensions and higher income — which can broaden the lenders available and how a case is assessed.

Can I get a large mortgage if I'm self-employed or a company director? Yes. Income from self-employment or a limited company — including retained profits and ongoing profitability — can be used, assessed through your accounts. You do not necessarily need to have drawn the income personally. Outcomes depend on the lender and the figures.

Can I get a large mortgage with adverse credit? Sometimes, depending on the nature and severity. A genuine one-off issue can often be explained to an underwriter; defaults and more serious adverse credit are more difficult and assessed case by case. There may be trade-offs in terms.

What criteria do I need to meet? Lenders generally look for clean credit, evidenced income and a suitable property. Where one of those is non-standard, the case may need to be structured differently — which is part of what a specialist broker manages.

How can Propertyze help? By structuring and positioning the case, matching it to the right lender, and presenting your full financial position to secure suitable terms.
