What salary do you need for a £300k house in the UK?
Disclaimer: This article is for general information only and does not constitute financial or mortgage advice. All figures are indicative and based on publicly available lender data as of 2026. Your actual borrowing capacity will depend on individual circumstances, lender criteria, credit history, and current interest rates. Always consult a regulated mortgage broker or financial adviser before making a decision.
The salary you need for a £300k house in the UK depends on two main variables: the size of deposit you can put down, and the income multiple your mortgage lender is willing to apply. As a practical starting point, most standard lenders will lend between 4 and 5 times your annual income. To borrow £300,000 on a standard 4.5× multiple, you would typically need a household income of around £66,700. To borrow the same amount at a more generous 5× multiple, you would need a household income of approximately £60,000.
Those figures assume you are borrowing the full £300,000. In practice, you will need a deposit in addition to the loan — so if you are buying a £300,000 property with a 10% deposit, you would be borrowing £270,000, and the salary requirement for a £300k house falls accordingly. This guide explains how lender income multiples work, what the monthly repayments look like, what other costs to factor in, and how joint applications change the picture.
How do mortgage lenders calculate how much you can borrow?
Most UK mortgage lenders use an income multiple to set the maximum they will lend. This is a straightforward calculation: the lender multiplies your annual gross income by a set number to determine the maximum loan they will offer. The most common income multiples used by mainstream lenders in 2026 range from 4.49 to 6.5, depending on the lender, the loan-to-value ratio, and the strength of the application.
For 300k mortgage affordability in the UK, the table below shows what single-applicant salary you would need to reach a £300,000 loan at different income multiples, based on publicly available lender criteria as of 2026:
| Income multiple | Salary required (solo) | Example lenders |
|---|---|---|
| 4.49× | ~£66,800 | Coventry BS, Pepper Money |
| 5.0× | ~£60,000 | Halifax, Santander, TSB, Virgin Money |
| 5.5× | ~£54,500 | Skipton BS, Accord, Principality BS |
| 6.0× | ~£50,000 | Nationwide (Helping Hand), Barclays, NatWest, Aldermore |
| 6.5× | ~£46,200 | HSBC Premier (qualifying applicants) |
Higher income multiples — such as those at 5.5× or 6× — typically come with qualifying conditions. These might include a minimum income threshold, a specific loan-to-value requirement, or restrictions on applicant type. HSBC Premier’s 6.5× product, for example, is reserved for customers with a Premier account meeting certain income or savings criteria. Always check the specific conditions that apply before factoring these multiples into your planning.
What salary do you need for a £300k house as a single buyer?
As a single buyer, reaching a £300,000 mortgage is achievable but typically requires a salary in the £50,000 to £67,000 range using standard lending criteria. If your income falls below this, there are still paths to consider:
Declare all income sources
Many lenders will consider supplemental income alongside your basic salary. This can include bonuses and commission (typically 50–100% of the annual amount), regular overtime, rental income, freelance earnings, benefits, and pension payments. If your total income — including these elements — reaches the required threshold, your qualifying salary figure is higher than your base pay alone suggests.
Extend the mortgage term
A longer mortgage term — 30 or 35 years rather than the standard 25 — can improve 300k mortgage affordability in the UK by reducing the monthly repayment that lenders must stress-test. Some lenders will also offer a higher income multiple when the monthly payment sits within a more comfortable affordability band. The trade-off is that you pay more interest in total over the life of the loan.
Clear existing debt
Mortgage lenders assess affordability not just on income, but on your existing financial commitments. Each £100 per month in credit card minimum payments, personal loan repayments, or car finance can reduce the mortgage amount you are offered by £6,000 to £10,000. Reducing or eliminating these commitments before applying can make a meaningful difference to your assessed affordability.
Consider professional mortgage products
Some lenders offer enhanced income multiples for specific professions — including doctors, dentists, barristers, solicitors, and qualified accountants — on the basis that these careers have predictable earnings progression. If you qualify, products at 5.5× or above may be accessible on a lower base salary than standard criteria would allow.
How does a joint application affect affordability?
A joint mortgage application allows two applicants to combine their income, which is often the most effective way to meet the salary needed for a £300k house in the UK without requiring a single very high earner. The lender applies the income multiple to the combined gross income of both applicants.
Here are some examples of how joint incomes reach the £300,000 threshold at a 5× multiple:
| Applicant 1 | Applicant 2 | Combined income | At 5× multiple |
|---|---|---|---|
| £35,000 | £25,000 | £60,000 | £300,000 |
| £40,000 | £20,000 | £60,000 | £300,000 |
| £45,000 | £18,000 | £63,000 | £315,000 |
| £30,000 | £30,000 | £60,000 | £300,000 |
Joint applications are subject to both applicants passing the lender’s credit assessment. If one applicant has a significantly weaker credit history, this may affect the rate or terms available — or limit the lenders willing to accept the application.
What deposit do you need for a £300,000 house?
The deposit you put down directly affects how much you need to borrow for a £300k mortgage — and the loan-to-value (LTV) ratio, which in turn affects the interest rate you are offered. A larger deposit generally means a lower LTV, a lower rate, and lower monthly repayments. The minimum deposit for a residential mortgage is currently 5% for most mainstream lenders.
| Deposit % | Deposit amount | Mortgage required | Property price |
|---|---|---|---|
| 5% | £15,789 | £300,000 | £315,789 |
| 10% | £33,333 | £300,000 | £333,333 |
| 15% | £52,941 | £300,000 | £352,941 |
| 20% | £75,000 | £300,000 | £375,000 |
| 25% | £100,000 | £300,000 | £400,000 |
Note that first-time buyers purchasing at £300,000 or below benefited from reduced stamp duty thresholds until April 2025. Rates have since reverted to standard thresholds. Use our stamp duty calculator to calculate what SDLT you will owe on your specific purchase price.

What are the monthly repayments on a £300,000 mortgage?
The monthly repayments on a £300k mortgage depend on the interest rate, the term length, and whether it is a capital repayment or interest-only mortgage. The table below shows indicative repayments for a capital repayment mortgage at various rates and term lengths, for illustrative purposes only. Actual rates will depend on your lender, deposit size, and application.
| Interest rate | 25-year term | 30-year term | 35-year term |
|---|---|---|---|
| 4.0% | £1,584/month | £1,432/month | £1,328/month |
| 4.5% | £1,667/month | £1,520/month | £1,420/month |
| 5.0% | £1,754/month | £1,610/month | £1,514/month |
| 5.5% | £1,842/month | £1,703/month | £1,611/month |
| 6.0% | £1,933/month | £1,799/month | £1,711/month |
These figures are for a £300,000 capital repayment mortgage where both capital and interest are repaid each month. At a 4% rate over 25 years, total repayment would be approximately £475,000 — meaning interest over the life of the mortgage amounts to around £175,000. Shortening the term or making overpayments reduces this significantly.

What else do you need to budget for beyond the mortgage?
Working out the salary needed for a £300k house in the UK is only part of the financial picture. A number of additional costs arise at and around the point of purchase that many first-time buyers underestimate. The main ones to factor into your total budget:
Stamp Duty Land Tax (SDLT)
Stamp duty is payable on all property purchases in England and Northern Ireland above £125,000 (£250,000 for first-time buyers until the 2025 threshold reversal). On a £300,000 purchase, a home mover would typically pay £5,000 in SDLT. A first-time buyer purchasing at £300,000 would pay £2,500, as the 0% band now reverts to £300,000 at standard threshold levels from April 2025. Use our stamp duty calculator to confirm the exact figure for your purchase.
Conveyancing fees
Conveyancing is the legal process of transferring ownership of the property into your name. It involves reviewing the title and contract, raising and responding to enquiries, carrying out property searches, managing the exchange and completion process, and registering your ownership with the Land Registry. Fixed-fee conveyancing for a £300,000 purchase typically ranges from around £800 to £1,500 plus disbursements. Get an instant fixed-fee quote from our residential conveyancing team before you complete your budget.
Survey costs
A mortgage lender’s valuation confirms the property is worth what you are paying — it is not a structural survey. If you want to understand the condition of the property before committing to purchase, you should commission an independent survey. A HomeBuyer Report typically costs £400–£700, and a full Building Survey £600–£1,500, depending on property size and location.
Mortgage arrangement fee
Many mortgage products include an arrangement fee of between £500 and £2,000. This is typically added to the mortgage balance rather than paid upfront, but it accrues interest over the term. Factor this into your comparison between different mortgage deals.
Removal costs and immediate works
Moving costs, any redecoration, furnishing, appliances, and any works needed immediately after moving in should all be part of your upfront budget. These are easily forgotten when focused on the headline purchase price, but they can add several thousand pounds to your total cost of moving.
Self-employed and contractor applicants
The salary requirement for a £300k mortgage works differently for self-employed applicants and contractors, because income is assessed differently by lenders.
Sole traders and partnerships
Most lenders assess a sole trader’s income on the net profit figure shown on the SA302 tax calculation, averaged over the two most recent tax years. If profit has been increasing year-on-year, some lenders will use the most recent year’s figure only, which can improve affordability.
Limited company directors
Directors who pay themselves a mix of salary and dividends are typically assessed on salary plus dividends drawn. A smaller number of lenders — including Halifax and Clydesdale — will instead look at salary plus the company’s retained profit, which often produces a higher assessed income and can significantly improve the loan amount available.
Day rate contractors
For contractors paid on a day rate, many specialist lenders assess income using the formula: day rate × 5 days × 46 working weeks per year. A contractor on £400 per day would therefore be assessed at £92,000 — comfortably above the £300k mortgage affordability threshold for most lenders, even at a 4.5× multiple.
What can reduce the amount you can borrow?
Lenders do not just look at income in isolation. They run a full affordability assessment that considers your financial commitments alongside your income. The following factors can each reduce the maximum loan available:
- Dependent children — each dependent reduces assessed affordability by approximately £8,000 to £15,000 depending on the lender
- Credit card balances — many lenders treat 3% of the total credit card balance as a monthly commitment; £10,000 in balances can reduce borrowing by £20,000 to £30,000
- Car finance — a £400/month PCP payment typically reduces maximum borrowing by £24,000 to £30,000
- Student loans — Plan 2 loan repayments (above £27,295 gross income) reduce disposable income and therefore affordability
- Existing mortgages or BTL properties — monthly payments on retained properties are factored into the assessment unless rental income demonstrably covers them
- A weak credit history — missed payments, defaults, or a low credit score may restrict the lenders willing to offer you a mortgage and the rates available
If any of these apply to you, speaking to a qualified mortgage broker before applying is particularly valuable. A broker can identify which lenders are most likely to work with your specific situation — avoiding hard credit searches with lenders unlikely to accept your application.
Next steps: from salary to completion
Once you have confirmed the salary you need for a £300k house is within reach — whether solo or jointly — the journey from mortgage readiness to completion involves several legal and practical steps. A conveyancing solicitor handles the legal side of your purchase: reviewing the contract and title, carrying out searches, raising enquiries with the seller’s solicitor, managing exchange and completion, and registering your ownership.
