Here is a genuine contradiction sitting inside the UK’s official statistics: by the measure the ONS uses to compare house prices with earnings, homes in England became more affordable in 2025 than they had been the year before. The ratio improved to 7.6 times median full-time earnings, down from 7.8, and was the lowest it had been since 2015.
Yet the cost of actually financing a home moved in the opposite direction during 2026. Average five-year fixed mortgage rates tracked by Zoopla were below 4% at the start of the year and around 4.8% by late August. On Zoopla’s assumptions, a buyer whose monthly budget could support a £200,000 mortgage in January could support only about £182,000 at the later rate — a 9% reduction in borrowing power without the buyer’s income or intended monthly payment changing. Zoopla’s August 2026 House Price Index sets out the calculation.
Both of those things can be true at the same time, about the same housing market. Neither statistic is wrong. They’re measuring different parts of what “affordable” actually means — and the gap between them explains why a headline announcing improving affordability can sit so uncomfortably next to the experience of somebody trying to buy a home right now.
This article tries to hold those different parts in view at once, rather than collapsing “is housing affordable?” into one deceptively simple number.
Two affordability questions, not one
The first question is: relative to what people earn, how expensive is a typical home? This is principally a price-to-income question, and it tends to move relatively slowly as house prices and earnings change.
The second is: given current mortgage rates and the amount being borrowed, how much does financing that home actually cost each month? This can change far more quickly because mortgage pricing responds to financial markets and expectations about future interest rates even when the price of the house itself has barely moved.
A home can therefore become cheaper relative to earnings while simultaneously becoming harder to finance if mortgage costs rise quickly enough. That is a fair description of the tension running through the UK market in 2026, and it’s why a single-sentence answer to “are homes becoming more affordable?” is unlikely to tell the whole story.
For an individual buyer, there are really four separate affordability gates:
| Affordability gate | The question it answers | Why it can block a purchase |
|---|---|---|
| Price relative to income | How expensive is the property compared with earnings? | Prices can simply be too high relative to what households earn |
| Deposit | How much cash or equity must the buyer provide upfront? | A buyer may afford the repayments but not have enough savings |
| Monthly mortgage cost | What does borrowing the money cost at today’s rate? | Higher rates can make the same loan substantially more expensive |
| Lender affordability | Will a lender actually advance the amount required? | Income, expenditure, debts and lending rules can limit borrowing |
A buyer can pass three of those tests and still fail the fourth. That is why a national affordability ratio can improve without making home ownership feel noticeably more accessible.
What the price-to-income data actually shows
According to the latest annual ONS housing affordability figures for England and Wales, the median home sold in England for £300,000 in 2025 against median full-time earnings of £39,300 — a ratio of 7.6. In Wales, a £213,000 median home against £35,800 earnings produced a ratio of 6.0.
England’s ratio fell significantly from 7.8 the previous year. Wales moved from 6.1 to 6.0, although the ONS says that annual change was not statistically significant.
More important than a single year’s movement is the longer direction. Since the affordability ratio peaked in 2021, median earnings across England and Wales have risen by 25%, while median house prices have increased by 5%. England’s 7.6 ratio is now its lowest since 2015.
That still doesn’t make England “affordable” by the ONS’s own broad analytical benchmark. The ONS uses five years of earnings as an indicator of affordability, and both England and Wales remain above it. That five-times figure is a statistical benchmark, though, not a rule saying a mortgage lender will lend somebody five times their salary.
The national average also hides a huge geographical range. London remained the least affordable English region at 10.6 times earnings, compared with 5.0 in the North East. At local-authority level the spread was wider again, ranging from 4.1 in Hyndburn and Kingston upon Hull to 25.2 in Kensington and Chelsea.
There is also another official ONS affordability measure, and it produces different numbers because it asks a different question.
The ONS Housing Purchase Affordability series compares house prices with disposable household income rather than the earnings of a full-time employee. Its latest UK-wide figures, for the financial year ending 2024, put the ratios at 7.9 in England, 5.4 in Wales, 5.3 in Scotland and 4.6 in Northern Ireland.
The two ONS measures aren’t rival attempts to calculate the same number. They use different definitions of income and different methodologies. The useful lesson is that even “the affordability ratio” isn’t one settled statistic. Before quoting one, it matters to know whose income and which house price are being compared.
The broad direction is nevertheless similar: affordability relative to income has improved from its recent worst point without remotely undoing the deterioration accumulated over much of the previous two decades.
Why the monthly bill tells a different story
Price-to-income ratios don’t know what interest rate your lender is charging.
That matters because mortgage costs can move much faster than house prices or earnings. During 2026, five-year fixed rates moved from below 4% in January towards 5% during the spring before easing back to around 4.8% by late August. The house itself did not have to become more expensive for the buyer’s position to worsen.
A simple example shows the effect.
Take a £300,000 home bought with a 10% deposit, leaving a £270,000 repayment mortgage over 30 years. At an illustrative interest rate of 4%, the monthly repayment is about £1,289. At 4.8%, it is about £1,417.
Nothing about the purchase price has changed. The deposit is unchanged. Yet the mortgage costs roughly £128 more each month, or about £1,530 more over a year.
That example excludes fees and assumes the same loan and term throughout, so it isn’t a mortgage quotation. It simply demonstrates why a relatively small movement in interest rates can outweigh a modest improvement in a national price-to-income ratio.
It also explains why falling house prices don’t necessarily restore affordability as quickly as people expect. A cheaper house financed at a materially higher rate can still leave a buyer with a larger monthly bill.
Deposits are a third, separate barrier
Even where the price-to-income ratio and monthly repayment appear manageable, the deposit remains a separate obstacle.
The distinction between the minimum deposit theoretically available and the amount successful buyers actually bring to a transaction is important. UK Finance’s Regional Mortgage Market Compendium 2026 shows that the average loan-to-value ratio among first-time buyers in 2025 was 77.6% in England, 82.2% in Wales, 83.2% in Scotland and 79.1% in Northern Ireland.
In other words, many buyers completing first purchases were putting considerably more equity into the transaction than the 5% minimum associated with the highest loan-to-value mortgages.
That does not mean somebody needs a 15%, 20% or 25% deposit to buy. These are averages across completed first-time-buyer loans, not minimum lending requirements. They do show why headlines about the availability of 95% mortgages don’t describe the financial position of every buyer who actually succeeds in purchasing.
The permanent Mortgage Guarantee Scheme, introduced in July 2025, is intended to support the continued availability of mortgages above 90% and up to 95% loan-to-value, allowing eligible first-time buyers and home movers to purchase with deposits as small as 5%.
That’s genuinely useful for somebody whose principal obstacle is accumulating a large deposit. But reducing the deposit hurdle does not solve the other affordability gates. A buyer still needs to satisfy a lender that the remaining mortgage is affordable.
The lender has its own affordability test
This is effectively a fourth test, and it’s often lost in discussions framed purely around prices and mortgage rates.
Mortgage lenders don’t simply ask whether the applicant believes they can meet this month’s repayment. They assess income, expenditure and existing financial commitments before deciding how much they’re prepared to lend. Depending on the mortgage, future interest-rate rises can also form part of that assessment.
The Financial Conduct Authority’s guidance on mortgage affordability explains that higher household expenditure can reduce the amount a lender is willing to advance even if the applicant’s salary hasn’t changed.
That means two households earning the same amount, looking at the same £300,000 property with identical deposits, can receive different borrowing decisions because their financial circumstances differ.
It also explains why a house costing four or five times someone’s income is not automatically mortgageable at four or five times their salary. A price-to-income ratio is a useful measure of the housing market. It is not a mortgage offer.
Why prices remain high in the first place
No single factor explains why UK homes remain expensive relative to incomes, and explanations that reduce it entirely to planning, housebuilding, mortgage credit, landlords or one particular government policy usually leave too much out.
The Office for Budget Responsibility’s housing-market analysis provides a useful way of seeing how those forces interact. Its modelling gives real income growth a major role in housing demand, while recognising that housing supply adjusts relatively slowly. Demographics, mortgage rates and credit conditions also affect the path of prices.
Supply plainly matters, but even here the effect is more complicated than “build more homes and prices fall immediately”. Where homes are built, what type they are, and where employment and population growth are concentrated all affect the result.
The OBR’s current forecast gives some sense of scale. It estimates that planning reforms announced in December 2024 could increase the housing stock by around 0.5% and reduce average house prices by roughly 0.8% by 2029 compared with what would otherwise have happened. That’s a forecast rather than an observed outcome, but it illustrates an important point: additional supply can put downward pressure on prices without being large enough on its own to transform affordability quickly.
Mortgage credit conditions matter too. During much of the 2010s, historically low interest rates allowed buyers to service larger loans for the same monthly repayment. Where housing supply couldn’t respond equally quickly, some of that additional borrowing capacity could feed into prices.
As mortgage rates rose after the ultra-low-rate period ended, that mechanism partly reversed. Borrowing became more expensive and house-price growth slowed. That helps explain how the price-to-earnings ratio could improve without the country experiencing the dramatic nominal house-price fall some observers expected.
Existing homeowner equity also matters. A homeowner who has spent years repaying a mortgage or benefiting from earlier house-price growth may arrive at the next transaction with substantial equity. A cash buyer requires no mortgage at all. Demand from those groups doesn’t disappear simply because a renter attempting a high loan-to-value first purchase can no longer make the numbers work.
That helps explain one of the market’s persistent frustrations: prices do not have to fall until they become affordable to the typical first-time buyer before transactions can continue.
Existing owners and first-time buyers are not playing the same game
This asymmetry deserves to be stated plainly.
Someone who bought a decade ago and has since repaid part of their mortgage will often bring accumulated equity to the next transaction. Someone renting and attempting to buy for the first time faces today’s purchase price, today’s financing costs and the need to create a deposit without existing housing equity.
Both appear as “buyers” in housing statistics. Their financial starting points can be completely different.
UK Finance’s 2026 regional analysis shows another side of that pressure. Across UK homebuyers in 2025, initial mortgage repayments absorbed an average 21.3% of gross borrower income — the highest level recorded since 2008. For first-time buyers, the corresponding averages included 22.2% in England, 21.0% in Wales, 19.8% in Scotland and 19.5% in Northern Ireland.
Those figures describe people who actually obtained mortgages. They don’t capture would-be buyers who could not pass the affordability test in the first place.
Renters face another constraint that homeownership affordability ratios largely miss: today’s rent affects tomorrow’s deposit.
According to the latest ONS private-rent figures, average UK private rent reached £1,393 a month in July 2026, 3.7% higher than a year earlier.
That doesn’t prove an individual renter cannot save. It does explain why the deposit question cannot be separated neatly from the rental market. A first-time buyer is often trying to accumulate capital for a home while simultaneously paying for the home they occupy now.
Regional inequality changes the entire calculation
None of these national figures describes one housing market.
An earnings-based affordability ratio of 5.0 in the North East and 10.6 in London represents a genuinely different challenge for somebody trying to buy. The required mortgage is different, the cash value of even the same percentage deposit is different, and a movement in mortgage rates has a much larger cash effect when applied to a larger loan.
Even within England and Wales, improvement hasn’t been universal. The ONS found affordability improved between 2024 and 2025 in 213 local authorities but worsened in 103.
That is why a national affordability figure is useful for understanding the direction of the country but much less useful for answering the personal question: “Can I afford to buy where I actually need to live?”
A buyer’s most relevant calculation is ultimately local and personal: the price of suitable homes in the places they can realistically live, the deposit they can assemble, the mortgage payment at the rate actually available to them, and the amount a lender is prepared to advance.
Is it actually getting better?
The honest answer requires separating several things that have been moving in different directions.
Price-to-income affordability has improved. In England, the ONS ratio has fallen from its 2021 peak to 7.6 in 2025, its best reading for a decade. That’s real improvement, even though homes remain expensive relative to earnings by longer-term standards.
Mortgage affordability became tougher during 2026. Five-year fixed rates rose materially from the levels available at the beginning of the year. The same monthly budget therefore buys less mortgage than it did in January, even before the property price changes.
Deposit accessibility remains a separate problem. High loan-to-value mortgages can reduce the minimum cash requirement, but the average first-time buyer completing a purchase still enters the market with considerably more equity than the theoretical 5% minimum.
Access to enough credit is another constraint again. Passing the deposit test does not guarantee that a lender’s affordability assessment will support the mortgage required for the property.
Those measures don’t move in lockstep, and treating “affordability” as though it were one number obscures more than it reveals.
The most accurate answer in 2026 is therefore less dramatic than either side of the usual argument. Homes in England and Wales have genuinely become somewhat less expensive relative to full-time earnings than they were at the recent peak. That is meaningful. It does not follow that buying one has become easy.
For somebody who already owns substantial housing equity, the market may look merely expensive. For somebody paying rent, building a deposit and borrowing most of the purchase price at today’s mortgage rates, the same home can still look almost impossibly far away.
Both experiences can exist in the same statistics. Understanding why is more useful than choosing one of them and calling it the definitive affordability story.
