Getting a £900,000 mortgage to buy a Property in the UK.

When trying to secure a £900,000 mortgage, it is well worth ensuring you apply to lenders with the most competitively priced rates and the most suitable acceptance criteria to meet your needs.

High-value mortgages often come with slightly stricter acceptance rules, but there is a good choice of lenders offering £900,000 mortgages. They usually require slightly larger deposit requirements and sometimes have higher arrangement fees.

Whether you’re buying in London, Surrey or Manchester, it’s essential to understand exactly what lenders expect before you apply.

Aaron Strutt, product director at Trinity Financial, says: "At the moment, there are lots of sub-4% mortgages, and some of the lenders are offering around 5.5 times salary income multiples. It is a good time to access a larger mortgage loan because there is so much competition between the banks and building societies.

"While many lenders offer soft credit footprints when you apply for a mortgage, it isn't worth applying to more banks or building societies than necessary."

How Much Deposit Do You Need for a £1 Million House?

The deposit depends on the loan-to-value (LTV) ratio:

• 90% LTV – Deposit of £100,000 = £900,000 mortgage.

• 85% LTV – Deposit of £150,000 = £850,000 mortgage.

• 80% LTV – Deposit of £200,000 = £800,000 mortgage.

• 75% LTV – Deposit of £250,000 = £750,000 mortgage.

Most lenders will expect 10–20% down on a £1,000,000 property. That means you’ll usually need between £100,000 and £200,000 in savings.

Income Requirements for a £900,000 Mortgage

UK mortgage lenders typically allow borrowing of around 5 times your household income, although some high earners or first-time buyers may be able to access 5–6 times this amount.

• Full £900,000 loan = Household income of £150,000–£200,000+

• £675,000 loan (with £225,000 deposit) = Household income of £150,000–£175,000

Lenders also factor in your monthly expenses, debts, and credit history when running affordability checks. If you have cars on finance, children in nursery or private school, or credit cards or loans, the maximum loan size may be reduced. This is where the lenders offering more generous income multiples are particularly useful. 

Which Lenders Offer £900,000 Mortgages?

High Street Banks

• Barclays for Intermediaries, HSBC, NatWest, and Santander for Intermediaries often offer some of the most competitively priced rates, and they have decent acceptance criteria.

• Suitable for borrowers with stable high incomes and have 5.5 times their salary income multiples, with varying acceptance criteria. You will need a clear credit history to qualify.

High Street Building Societies

• Nationwide for Intermediaries and Skipton Building Society often have good rates and generous acceptance criteria. They also offer some of the most competitively priced rates. Nationwide's Helping Hand scheme is particularly good for first-time buyers.

Specialist Lenders

• Kensington, Precise Mortgages, Family Building Society or Accord. 

• Options for self-employed, contractors, or non-standard applicants if you do not qualify with the biggest banks and building societies. 

Mortgage Incentives on High-Value Loans

Many mortgage lenders offer incentives to attract large loan borrowers, including:

• Free property valuations (worth £500–£1,500). This does not cover a full survey, so you will need to pay extra if you want the property checked over.

• Cashback deals (£250–£1,000)

• Fee-free remortgages (covering legal costs)

• More competitively priced rates for higher earners and Premier Banking customers.

Current Mortgage Rates for £900,000 Loans

• Fixed-rate mortgages – Typically 3.75%–5.5% (2025), offering repayment certainty

• Tracker mortgages – Linked to the Bank of England base rate, useful if rates fall

• Offset mortgages – Ideal for high-earners with savings, as you can reduce interest costs

Final Thoughts

A £900,000 mortgage is achievable if you have:

• A strong income (typically £120,000+ household income)

• A clean credit history and evidence of affordability

• You are buying a standard house or flat

Compare deals across high street banks, building societies, and specialist lenders, and always factor in arrangement fees and incentives before choosing your mortgage.

Your mortgage is secured on your property. Your property may be repossessed if you do not keep up repayments on your mortgage
