Understanding a £1,000,000 Mortgage
A £1,000,000 mortgage places you in the premium segment of the UK property market. At 4.5% over 25 years, monthly repayments are £5,558, representing a substantial financial commitment of £66,700 per year, or approximately £183 per day.
The total interest on a £1,000,000 mortgage is £667,497 over 25 years - more than half the original loan amount. At higher rates of 6.0%, the interest balloons to £932,904, which is why rate shopping is even more important at this level. Even a 0.25% reduction saves £42,283 over the term.
Qualifying for a £1,000,000 mortgage requires a household income of approximately £222,222 at standard 4.5x multiples. For high earners, some private banks and specialist lenders offer higher multiples or more flexible affordability assessments. A mortgage broker specialising in high-value lending can often access deals not available directly from high street lenders.
With a 10% deposit on a £1,111,111 property, you would also face stamp duty of approximately £52,361. The total upfront costs (deposit + stamp duty + fees) could exceed £166,472, making careful financial planning essential.
Mortgage Tips for £1,000,000 Borrowers
Private Bank Lending
For mortgages of £1,000,000 and above, private banks and wealth management firms often offer more competitive rates and flexible terms than high street lenders. They may consider investment portfolios, bonus structures, and foreign income that standard lenders cannot. The savings on a 0.5% rate reduction amount to £83,987 over the term.
Interest-Only Consideration
On £1,000,000, an interest-only mortgage reduces monthly payments to approximately £3,750 (vs £5,558 on repayment) - a saving of £1,808 per month. However, you must have a credible repayment strategy. Most lenders require LTV under 75% and a clear plan to repay the capital. This approach is common among buy-to-let investors and high-net-worth borrowers.
Rate Lock and Booking Fees
At this mortgage level, arrangement fees of £1,000-£2,000 are common but represent a small percentage of the loan. Always compare the overall cost (rate + fees) rather than just the headline rate. On £1,000,000, a deal at 4.5% with a £2,000 fee may be better than 4.6% with no fee - saving £15,074 over 25 years.
Stamp Duty Planning
On a property worth £1,111,111 (assuming 90% LTV), stamp duty is approximately £52,361. For additional properties, add the 5% surcharge (£55,556). Budget for these costs separately from your deposit. Some buyers stagger purchases to manage the timing of selling and buying, potentially avoiding the additional property surcharge if their existing home sells within 36 months.
What If? Scenarios for £1,000,000 Mortgage
If Interest Rates Drop by 1%...
A 1% rate reduction (from 4.5% to 3.5%) would reduce your monthly payment from £5,558 to £5,006, saving £552 per month (£6,625 per year). Over 25 years, this saves £165,627 in total interest. With the Bank of England base rate at 4.5%, rate movements depend on inflation and economic conditions.
If You Overpay by 10% Each Month...
Increasing your payment from £5,558 to £6,114 (an extra £556 per month) could reduce your mortgage term by approximately 4 years and save around £120,150 in interest. Most lenders allow 10% annual overpayment without penalty during a fixed-rate period. Check your specific mortgage terms before overpaying.
20-Year vs 30-Year Term...
Choosing a 20-year term costs £6,326 per month (an extra £768 vs 25 years) but saves £149,139 in total interest. A 30-year term reduces payments to £5,067 per month (saving £491) but costs an extra £156,570 in interest over the life of the mortgage. The right choice depends on your monthly budget and long-term financial goals.
Frequently Asked Questions: £1,000,000 Mortgage
How much are monthly payments on a £1,000,000 mortgage?
At 4.5% interest over 25 years, monthly payments on a £1,000,000 mortgage are £5,558. At 3.5%, payments drop to £5,006. At 6.0%, they rise to £6,443. The exact rate you receive depends on your deposit size, credit score, and income.
What salary do I need for a £1,000,000 mortgage?
Most UK lenders offer mortgages at 4-4.5 times your annual income. For a £1,000,000 mortgage, you would typically need a household income of approximately £222,222. Joint applicants can combine incomes. Some lenders for professionals (doctors, lawyers) may offer up to 5.5x, requiring £181,818.
How much deposit do I need for a £1,000,000 mortgage?
The minimum deposit is typically 5% (£52,632 on a £1,052,632 property). However, a 10% deposit (£111,111 for a £1,111,111 property) unlocks better rates, and 25% LTV (£333,333) gives access to the lowest rates available. A larger deposit significantly reduces your monthly payments and total interest.
How much interest will I pay on a £1,000,000 mortgage?
Over 25 years at 4.5%, total interest on £1,000,000 is £667,497. You would repay £1,667,497 in total. Reducing the rate by just 0.5% saves approximately £83,987 in interest over the full term.
Should I get a fixed or variable rate mortgage for £1,000,000?
A fixed rate on £1,000,000 gives payment certainty - your £5,558 payment will not change during the fixed period (typically 2 or 5 years). A variable or tracker rate starts lower but can increase if the Bank of England raises rates. At the current base rate of 4.5%, if rates rise by 1%, your payment could increase by approximately £583 per month.
Can I get a £1,000,000 interest-only mortgage?
Interest-only payments on £1,000,000 at 4.5% would be approximately £3,750 per month (vs £5,558 on repayment). However, the full £1,000,000 must be repaid at the end of the term. Most lenders require a clear repayment strategy (investments, property sale, pension) and typically restrict interest-only to 75% LTV or less.
Do I need a specialist lender for a £1,000,000 mortgage?
While high street lenders can provide mortgages up to £1,000,000, private banks and specialist lenders often offer better terms for high-value mortgages. They may offer more flexible affordability assessments, consider bonus income and investment portfolios, and provide dedicated relationship managers. A whole-of-market mortgage broker can access these specialist deals.

Affordability Check: £1,000,000 Mortgage
Before applying for a £1,000,000 mortgage, it is essential to understand whether the repayments are sustainable for your household. UK lenders use income multiples and stress testing to assess affordability. Below is a comprehensive breakdown of the key affordability metrics for this mortgage amount.
| Affordability Metric | Value |
|---|---|
| Required Salary (4.5x multiple) | £222,222 |
| Required Salary (4x conservative) | £250,000 |
| Monthly Payment at 4.5% over 25 years | £5,558 |
| Stress Test Payment at 7.5% (+3%) | £7,390 |
| Maximum Housing Cost (35% of gross monthly) | £15,881 |
| Salary Needed for 35% Rule | £190,571 |
Most UK lenders do not simply use the advertised rate when assessing affordability. Instead, they apply a stress test, typically at the current rate plus 3 percentage points. For a £1,000,000 mortgage, this means your lender will check whether you can afford monthly payments of £7,390 (at 7.5%), not just the £5,558 you would actually pay at 4.5%. This stress test ensures borrowers can cope if interest rates rise significantly during the mortgage term.
For mortgages above £400,000, you may wish to consider private bank or specialist lender options. Private banks such as Coutts, C. Hoare & Co, and Handelsbanken often have more flexible affordability criteria for high-net-worth borrowers, including consideration of bonus income, investment portfolios, and foreign earnings. Some specialist lenders offer income multiples of up to 5.5x or even 6x for certain professions.
The 35% rule is a widely used affordability guideline suggesting that no more than 35% of your gross monthly income should go towards housing costs. For monthly payments of £5,558, this means you would need a gross annual salary of at least £190,571 to comfortably afford this mortgage without stretching your finances.
How We Calculate Mortgage Payments
Our mortgage calculations use the standard amortisation formula used by UK lenders. Monthly payments are calculated as: P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of payments. We show repayment mortgages (capital and interest). Interest-only payments would be lower but require a separate repayment strategy. Rates shown are illustrative; actual rates depend on your LTV ratio, credit score, and chosen lender.

Understanding UK Mortgages: A Complete Guide
A mortgage is a long-term loan secured against a property. In the UK, most mortgages run for 25 to 35 years, during which you make monthly payments covering both the capital (the amount borrowed) and the interest charged by the lender. The amount you can borrow, the interest rate you receive, and your monthly repayments all depend on several key factors including your income, deposit size, credit history, and the type of mortgage product you choose.
Types of UK Mortgages
Understanding the different mortgage types available is essential for making the right choice:
- Fixed-rate mortgages (2, 3, 5 or 10 year) – Your interest rate stays the same for the fixed period, giving you predictable monthly payments regardless of what happens to the Bank of England base rate. Most popular choice for budgeting certainty.
- Tracker mortgages – The rate follows the Bank of England base rate plus a set margin (e.g. base rate + 0.75%). Your payments move up or down as the base rate changes, offering transparency but less predictability.
- Standard Variable Rate (SVR) – The lender's default rate, which you typically move onto after a fixed or discount deal ends. SVRs are usually the highest rates available and can change at any time at the lender's discretion.
- Discount mortgages – A reduction off the lender's SVR for a set period (e.g. SVR minus 1.5% for 2 years). Payments can still vary because the underlying SVR can change.
- Offset mortgages – Your savings are linked to your mortgage balance, reducing the amount on which interest is calculated. For example, with £30,000 in savings offset against a £200,000 mortgage, you only pay interest on £170,000. Your savings remain accessible but earn no interest.
Loan-to-Value (LTV) and Interest Rates
Your loan-to-value ratio – the percentage of the property price you borrow – is one of the biggest factors affecting the interest rate you are offered. A lower LTV means a larger deposit and typically better rates:
| LTV Band | Deposit Example (£250k property) | Typical Rate Impact |
|---|---|---|
| 95% LTV | £12,500 deposit | +0.5–1.0% above best rates |
| 90% LTV | £25,000 deposit | Competitive rates available |
| 85% LTV | £37,500 deposit | Good rate improvement |
| 75% LTV | £62,500 deposit | Best rates generally available |
| 60% LTV | £100,000 deposit | Lowest rates on the market |
How Lenders Assess Affordability
UK lenders do not simply multiply your salary to determine how much you can borrow. They conduct a thorough affordability assessment that includes:
- Income multiples – Most lenders offer 4 to 4.5 times your gross annual income as a starting point. Some specialist lenders may stretch to 5 or 5.5 times for certain professions.
- Stress testing – Lenders must check you can afford payments if rates rise by approximately 3 percentage points above the revert rate. This is a regulatory requirement from the Financial Conduct Authority.
- Existing debts and commitments – Credit card balances, car finance, student loans, childcare costs, and other regular outgoings are all factored in. Reducing debts before applying can increase your borrowing power.
Overpayment Benefits
Most UK mortgage lenders allow you to overpay up to 10% of your outstanding balance each year without incurring early repayment charges. Overpaying has two powerful benefits: it reduces the total interest you pay over the life of the mortgage, and it shortens the term, meaning you become mortgage-free sooner. Even modest regular overpayments can save thousands of pounds and shave years off your mortgage. Always check your specific mortgage terms before making overpayments, as exceeding the allowance during a fixed-rate period may trigger penalty charges.
Common Mortgage Questions
What is the current Bank of England base rate?
The current Bank of England base rate is 4.5% (as of February 2026). Tracker mortgages follow this rate plus a margin set by the lender. Fixed-rate mortgages are priced independently by lenders based on swap rates and market conditions, so they do not move directly with the base rate.
Should I get a fixed or variable rate mortgage?
A fixed-rate mortgage gives you certainty – your monthly payments will not change during the fixed period, making it ideal if you want predictable budgeting. A variable or tracker rate can be cheaper initially but carries the risk of rate increases if the Bank of England raises the base rate. Consider your risk tolerance, how long you plan to stay in the property, and whether you could afford higher payments if rates rise. Many borrowers choose a 2 or 5 year fixed deal and then reassess when the fixed period ends.
Can I switch my mortgage to get a better rate?
Yes, this is called remortgaging. You can switch to a new deal either with your existing lender (a product transfer) or with a different lender when your fixed or discount period ends to avoid early repayment charges. When comparing deals, factor in arrangement fees (typically £500–£1,500), valuation fees, and any legal costs to ensure that switching genuinely saves you money overall. A mortgage broker can help you compare the full market.
