Why You Can't
Afford a House
The median home in England costs 7.6 times median earnings. In 1997 it was 3.5 times. This is not a market failure. It is a market working exactly as it was designed to work — by people who already owned homes.

on median salary
A home in 1997 cost £55,000. By 2025, the average home costs £300,000. Median full-time earnings are £39,300.
It is the cumulative result of deliberate policy choices.
01
The Hook
A Home Is No Longer a Place to Live.
It's a Financial Instrument.
The ratio of house prices to earnings was 3.5 to 1 in 1997. By 2025, it had reached 7.6 nationally and 10.5 in London.
This is the cumulative result of a series of deliberate policy choices — most made by people who already owned homes and had every incentive to keep prices rising.

The Mechanism
How Housing Became a Wealth Engine
Three policy decisions converted the UK housing stock from shelter into a leveraged investment asset.
Right to Buy (1980)
Margaret Thatcher sold 1.9 million council homes at an average 44% discount. The receipts were not reinvested in new social housing. Today, there are approximately 4 million fewer social homes than in 1980.
Buy-to-Let Mortgages (1996)
Made residential property investment available to anyone with a deposit. First-time buyers were now competing against investors. Buy-to-let landlords have earned returns of almost 1,400% since 1996.
Help to Buy (2013–2023)
The government's solution to unaffordable housing was to help people borrow more. The scheme's own evaluation found it had 'a statistically significant positive effect on house prices.' It cost £29 billion and made housing less affordable.
03
Context — The Planning System
Where Scarcity Is Manufactured
Agricultural land costs approximately £10,000 per acre. With planning permission: approximately £2.5 million per acre. That is a 250-fold increase in value — created by a bureaucratic decision.
The planning system creates artificial scarcity of developable land.
The Numbers
- Planning permission was granted for only 209,781 new homes in the year to September 2025
- London saw a 72% drop in approved units in Q3 2025
- At current rates, England will deliver approximately 1.05 million — 30% short of the 1.5 million target
NIMBYism is entirely rational behaviour. If your home is your primary financial asset, opposing new development is in your direct financial interest.
04
The Mechanism
The Leasehold Trap:
You Own Your Flat. Or Do You?
There are approximately 4.83 million leasehold dwellings in England — 19% of the total housing stock.
The Marriage Value Problem
Below 80 years, a lease depreciates rapidly. The leaseholder must pay the freeholder 50% of the increase in the property's value that results from extension.
The Leasehold and Freehold Reform Act 2024 aims to abolish marriage value and extend standard lease terms to 990 years. Most of its provisions are not yet in force.
05
Context
Stamp Duty: The Tax That Froze the Market
Stamp Duty is in practice a lock-in mechanism that prevents people from moving.
The total cost of moving in London — stamp duty, legal fees, estate agent fees, survey — hit £32,786 in 2025. That is 69% of the median London salary, spent simply to change address.
The consequence is a frozen market. Home moves have fallen to their lowest level in decades.
The government collects £11.6 billion a year from this dysfunction.
06
The Mechanism
The Deposit Paradox:
Two Impossible Things
Average private rents: £1,430 per month. A 10% deposit: £30,000.
The Maths
A 28-year-old on the median salary takes home around £2,393 per month. After rent and essentials, they have roughly £413 per month to save. Saving £30,000 takes just over six years.
During those six years, house prices continue to rise. The deposit target moves.
The cruel irony: the monthly mortgage repayment would be less than the rent they are currently paying. The barrier is the upfront cost of entry.
07
So What
Who Benefits — and Why Reform Is Nearly Impossible
The UK housing crisis persists not because nobody knows how to fix it, but because the people with the power to fix it benefit from it remaining broken.
| Beneficiary | How They Benefit | Political Power |
|---|---|---|
| Existing homeowners (65%) | Rising prices increase their net worth. | Very high. Higher voter turnout. |
| Banks and lenders | Larger mortgages, larger interest payments. | High. Systemic importance. |
| Property developers | Land banking is more profitable than building. | High. Major donors. |
| The Treasury | £11.6bn/year in SDLT. IHT. CGT. | Very high. |
| Non-owners (renters) | They lose. Entirely. | Low. Younger, more mobile. |
The 2024 General Election showed the first signs of this calculus shifting.
08
The Scandal
The Land Banking Scandal
Developers have secured planning permission for over 1.4 million homes since 2007 and not built them. Constrained supply keeps prices high while they wait.
The planning system is blamed for the housing shortage. The developers holding 1.4 million unbuilt permissions are rarely mentioned.

Context
How Other Countries Solved It
Three cities demonstrate that radically different outcomes are achievable.
Vienna: The State as Landlord
220,000 city-owned apartments, 60% of population in municipal or cooperative housing. Rents average €500/month. Price-to-earnings ratio: 6.2×. The state sets a price anchor for the entire market.
Singapore: The State as Builder
80% of residents live in HDB flats, purchased at subsidised prices. Price-to-earnings ratio: 4.8×. The state removed the profit motive from primary housing supply.
Tokyo: The State That Got Out of the Way
National zoning law overrides local objections. Tokyo builds 130,000 new homes per year — more than the entire country of England. Houses depreciate like cars. Rent: ~£420/month.
What these three cities share is a political decision that housing is too important to be left entirely to the market.
One Takeaway
The UK housing crisis is not a market failure. It is a market success — for the 65% who own homes, the banks, the developers, and the Treasury. Every structural feature reinforces the same outcome: high prices, constrained supply, and a transfer of wealth from the young to the old.
The Dinner Party Line
"You pay more in rent than you would in mortgage repayments, but you can't get a mortgage because you can't save a deposit because you're paying too much in rent. Meanwhile, developers are sitting on 1.4 million unbuilt homes — because building them would reduce prices."
