How Much House Can I Afford UK 2026?

Quick answer

The fastest way to estimate how much house you can afford in 2026 is to multiply your gross annual income by 4.5. That gives the maximum mortgage most high-street lenders will offer. Add your deposit, and you have the approximate purchase price you can target.

So someone earning £50,000 can usually borrow around £225,000. With a £25,000 deposit, that supports a house priced at roughly £250,000. A couple with a joint income of £80,000 can borrow around £360,000, putting a £400,000-plus home within reach with a typical deposit.

But the income multiple is only half the story. Lenders also run an affordability assessment that looks at your actual outgoings and stress-tests the loan against higher interest rates. Two people on identical salaries can be offered very different amounts depending on their debts, childcare costs and credit history. This guide walks through both the multiples and the affordability test, with worked examples on £30k, £50k and £80k incomes.

The income multiple: 4.5x is the benchmark

Since the post-2014 mortgage rules, UK lenders have largely settled on a loan-to-income (LTI) cap of around 4.5 times gross income. Regulators allow each lender to write a limited share of their lending above 4.5x, which is why you will see some products advertised at 5x or even 5.5x income.

Higher multiples are usually reserved for:

• Higher earners (often those with incomes above £50,000-£75,000), who have more disposable income left after essentials.
• Professionals such as doctors, dentists, accountants, lawyers and some other qualified roles, where lenders offer "professional mortgages" at up to 5.5x or 6x.
• Larger deposits, which reduce the lender's risk and can unlock a higher multiple.

For most ordinary applicants, though, 4.5x is the realistic planning figure. Use the

The deposit: how much you really need

The mortgage covers most of the price; the deposit covers the rest. Your deposit as a percentage of the price determines your loan-to-value (LTV) — and LTV is the single biggest driver of the interest rate you are offered.

On a £250,000 home, a 5% deposit is £12,500 and a 10% deposit is £25,000. Pushing from 5% to 10% can shave a noticeable amount off your monthly payment because you drop into a cheaper rate band and borrow less. Every step down the LTV ladder helps on both counts.

The affordability stress test

Getting under the income multiple is necessary but not sufficient. Since the Mortgage Market Review, lenders must check that you could still afford the payments if interest rates rose. In practice that means:

1. Income assessment — they verify your gross income from payslips, tax returns or accounts (for the self-employed, usually two to three years).
2. Committed expenditure — they deduct your regular outgoings: existing loans, credit cards, car finance, childcare, school fees, maintenance payments and other credit commitments.
3. Stress rate — they test whether you could still pay the mortgage at a rate several percentage points above the product rate, to make sure a future rise would not break your budget.

This is why two applicants on the same £50,000 salary can be offered very different amounts. Someone with £400 a month of car finance and two children in nursery has far less affordability headroom than a debt-free single applicant, even though their income multiple is identical.

Worked example 1: £30,000 income

Aisha earns £30,000 and has saved a £20,000 deposit.

• Income multiple (4.5x): £135,000 maximum mortgage.
• Purchase price: £135,000 + £20,000 deposit = £155,000.
• LTV: the £135,000 loan on a £155,000 home is 87% LTV — just inside the 85-90% band, so she gets a reasonable but not the cheapest rate.

If Aisha can stretch her deposit to £25,000, she could buy at the same price with a lower LTV and a better rate, or buy slightly more house. On a single modest income, the multiple is the binding constraint, so a bigger deposit mainly helps with the rate rather than the maximum price.

Worked example 2: £50,000 income

Ben earns £50,000 with a £30,000 deposit and no debts.

• Income multiple (4.5x): £225,000 maximum mortgage.
• Purchase price: £225,000 + £30,000 = £255,000.
• LTV: the £225,000 loan on a £255,000 home is 88% LTV.

Because Ben is debt-free and a clean applicant, some lenders might offer him 5x income (£250,000), pushing his budget towards £280,000. But he should check the monthly payment is comfortable — borrowing the maximum at a high multiple leaves little slack if rates rise or his circumstances change.

Worked example 3: £80,000 joint income

Chloe and Dev have a combined income of £80,000 and a £50,000 deposit.

• Income multiple (4.5x): £360,000 maximum mortgage.
• Purchase price: £360,000 + £50,000 = £410,000.
• LTV: the £360,000 loan on a £410,000 home is 88% LTV.

A joint application pools both incomes, so couples typically have far more buying power than singles. If they qualify for 5x income, their mortgage ceiling rises to £400,000 and their budget approaches £450,000. But the affordability test still applies to the combined household — childcare costs in particular can take a big bite out of a couple's borrowing capacity once children arrive.

The hidden costs of buying

The deposit and mortgage are only part of what you need. Budget for:

• Stamp Duty Land Tax (SDLT) — in England and Northern Ireland, first-time buyers pay nothing up to £300,000 and 5% on the slice from £300,001 to £500,000; other buyers pay from £125,000 upwards. Work out your exact bill with the

  . Scotland and Wales have their own LBTT and LTT systems.
• Legal and conveyancing fees — typically £1,000-£2,000 including searches.
• Survey — a homebuyer's report costs £400-£900; a full structural survey more.
• Mortgage arrangement fee — often £1,000-£1,500, sometimes addable to the loan (though that means paying interest on it).
• Valuation fee — sometimes free, sometimes a few hundred pounds.
• Moving costs — removals, and possibly some new furniture.

A common mistake is to spend every penny on the deposit and have nothing left for these costs, which can easily total £5,000-£15,000 depending on the price and whether stamp duty applies.

How interest rates change what you can afford

Income multiples set the loan ceiling, but the interest rate sets the monthly payment — and that is what determines whether the home is genuinely affordable. A £225,000 mortgage over 25 years costs noticeably more per month at 5% than at 4%, and the stress test bakes in a buffer above the headline rate.

This is why a larger deposit is doubly valuable: it both reduces the loan and unlocks a lower rate band, so the monthly payment falls on two fronts. Before you commit, run the loan at a rate a couple of points higher than today's to make sure you would still be comfortable if you remortgage onto a higher rate in a few years. The

What counts as income for a mortgage

Lenders do not simply take your basic salary. What they count — and how much weight they give it — varies, and it can materially change your borrowing power:

• Basic salary is counted in full and is the foundation of the calculation.
• Regular overtime, shift allowances and bonuses are often counted at 50-100%, depending on how reliable they are. Two or three years of consistent bonuses carry more weight than a one-off.
• Commission is usually averaged over the last one to two years.
• Self-employed income is typically assessed on two to three years of accounts or tax returns, using an average (or sometimes the latest year if lower). Newly self-employed applicants with under a year of accounts struggle to borrow.
• Benefits and pensions such as Child Benefit, certain tax credits and pension income may be counted by some lenders, especially for older borrowers.
• Second jobs and rental income can sometimes be added, again subject to evidence.

If a chunk of your income is variable, it is worth approaching a lender or broker who treats it generously. Two lenders can value the same bonus-heavy package very differently, which directly affects your 4.5x ceiling. The

How your credit profile changes the picture

Affordability is not only about income and outgoings — your credit history affects both whether you are approved and the rate you get. Lenders look at:

• Payment history — missed payments, defaults and County Court Judgments (CCJs) can reduce your options or push you to specialist lenders at higher rates.
• Existing credit commitments — as covered above, these reduce affordability through the stress test.
• Credit utilisation — running credit cards near their limit can dent your score even if you pay on time.
• Electoral roll registration and a stable address history, which help verify your identity.

In the year before applying, the sensible moves are to check your credit report with all three main agencies, correct any errors, register to vote, avoid new credit applications, and keep card balances low. A clean profile can be the difference between a 90% LTV deal at a competitive rate and being declined or offered a much higher rate.

The role of the mortgage term

The term — how long you take to repay — has a big effect on both the monthly payment and what you can afford. A longer term (say 35 years instead of 25) lowers the monthly payment, which can help you pass the affordability test and borrow more. The trade-off is that you pay far more interest over the life of the loan, and lenders will not let the term run too far past your expected retirement age.

This creates a tension for older buyers: someone applying at 45 may be limited to a 20-year term, pushing up the monthly payment and reducing affordability, even on a strong income. Younger buyers have more flexibility to stretch the term. When you model your options, try a couple of different terms in the

to see how the monthly figure and total interest shift — then pick the shortest term you can comfortably afford, rather than automatically defaulting to the longest.

A sensible way to set your budget

Rather than borrowing the absolute maximum, many buyers work backwards from a comfortable monthly payment:

1. Decide what you can comfortably pay each month (a common rule of thumb is to keep housing costs under about 35% of net income).
2. Use the mortgage calculator to find the loan that produces that payment at a realistic rate and term.
3. Add your deposit to get your target purchase price.
4. Check that price sits within your 4.5x income ceiling — if it does, you have built in a safety margin.

This approach protects you against rate rises and life changes far better than maxing out the multiple. The

and the together give you both the ceiling and the comfort figure.

The bottom line

In 2026, start with 4.5 times your gross income for your mortgage ceiling, add your deposit, and you have a realistic purchase-price target. Some applicants can borrow 5x or 5.5x, but the affordability stress test — which weighs your actual outgoings and tests you against higher rates — is the real gatekeeper. Clearing debts, growing your deposit and choosing a comfortable monthly payment rather than the maximum loan will leave you in a far stronger position. And whatever you target, set aside several thousand pounds for stamp duty, legal fees and the other hidden costs that come with buying a home.
