In 2017, Britain's housing market was worth £1.32 trillion. Not cheap, but manageable for many. Then came five years that changed everything.

By 2021, that figure hit £1.46 trillion. The jump in that final year alone? £92 billion. To put that in perspective, that's more than the government spends on education annually.

The trajectory tells the story of two very different Britains emerging. In 2018, prices crept up modestly to £1.34 trillion. Nothing dramatic. In 2019, they actually fell back to £1.33 trillion. For a brief moment, it looked like the market might be cooling.

Then 2020 arrived. COVID should have crashed property values. Instead, they soared to £1.37 trillion. Stamp duty holidays, remote work, and record-low interest rates turned a pandemic into a property gold rush.

But 2021 was when the market truly exploded. That 6.7% jump in a single year created more housing wealth than most people will earn in their entire careers. For existing homeowners, it was like winning a lottery they never bought a ticket for.

Here's what those numbers mean in human terms. Every homeowner in Britain saw their property value rise by an average of £6,500 in 2021 alone. They did nothing for it. They went to work, paid their mortgages, watched Netflix. Their houses earned more than many people's salaries.

Meanwhile, first-time buyers watched the goalposts move further away every month. A couple saving £200 monthly for a deposit found that house prices were rising faster than they could save. The dream of ownership slipped further from reach with every ONS release.

The winners? Anyone who bought before 2020. Their equity ballooned while they slept. Property became the best investment nobody planned to make.

The losers? Renters paying inflated rents to landlords whose mortgages stayed the same while their property values doubled. Young families priced out of areas their parents bought into easily.

Those five years didn't just change house prices. They restructured British society along lines of property ownership. On one side: homeowners who gained wealth without effort. On the other: renters falling further behind despite working harder than ever.

The £92 billion question is what happens next. Those gains came from extraordinary circumstances that won't repeat. But the damage to affordability? That's permanent. (Source: ONS, House prices by local authority)
