London’s house price cycle has long been defined by pronounced swings between periods of outperformance and consolidation. One way to observe these fluctuations is by looking at how London’s prices move relative to the national average.
The London premium is the extra money it costs to buy a property located in the capital. We have defined this as the ratio of London’s average house price to England’s. We can see this premium reaching clear peaks and troughs through the years. London’s relative strength tends to build in waves, with peaks in 1972, 1987, 2001 and, most recently, 2016.
These peaks typically follow a period where the capital has significantly outpaced the rest of the country, before the pendulum swings back and regions outside London begin to catch up. Historically, these peak‑to‑peak cycles last around fifteen years. The post‑2008 period provides a clear illustration of this pattern.
Why is London the first to recover after a crash?
After the 2008 financial crisis, London was the first place to revive. From 2010 to 2016, the capital powered ahead, with prices rising by 66% compared to 28% in England. This earlier and stronger recovery reflected several characteristics of the London market.
London housing has long been perceived as a relatively safe investment for international buyers. Strict property laws have helped underpin its appeal as a stable asset during periods of uncertainty. So, when house prices dropped and the sterling weakened, international buyers sought London property, providing disproportionate support to prices within the capital.
Conditions in the domestic market also differed from those elsewhere. Tighter credit conditions reduced the pool of mortgage‑dependent buyers. London, however, had a relatively high share of cash purchasers, who were less exposed to these constraints and helped support demand in the years following the financial crisis.
Compounding this, London is relatively scarce in land, which limited the scope for housing supply to respond as demand began to recover. With new construction constrained, a larger share of the market adjustment occurred through prices rather than increased supply.
By March 2016, the premium reached a record 2.37x, just before the arrival of the 3% second‑home stamp duty surcharge.
The cycle is becoming longer
What’s most interesting is that these cycles have been becoming longer. Rather than the typical five‑year cooling phase, London has now underperformed for almost a decade. We would usually expect London house prices to have started to begin an upward trajectory already, given the typical time it takes for a market to go through the house price cycle.
However, London has been going through it for a little longer this time. The prolonged downturn can be explained by a series of policy changes which first began to weigh on demand in the capital during the mid‑2010s.
In 2014, stamp duty land tax was restructured into a progressive system, increasing transaction costs most sharply at the top end of the market. Given London’s higher price base, this disproportionately affected activity in the capital.
This was followed in 2016 by the introduction of an additional 3% surcharge on second homes and buy‑to‑let properties, dampening investor demand in areas where it had historically been most concentrated.
Further measures followed. From 2021, non‑resident buyers became subject to an additional 2 percentage‑point surcharge. As overseas investment is heavily skewed towards London, the effect of these changes fell most heavily on the capital, steadily eroding a key source of marginal demand.
Alongside these policy shifts, broader structural forces began to reshape London’s appeal. Brexit reduced the inflow of internationally mobile professionals, weakening a traditional source of housing demand.
The pandemic then accelerated changes in buyer preferences, as remote and hybrid working made it easier for households to trade proximity for space and value. While some of this shift has since unwound, it has not fully reversed.
More recently, higher interest rates have added a further headwind. With prices starting from a higher level, London has been more exposed to the affordability effects of rising borrowing costs, reinforcing the capital’s relative underperformance.
The outlook
The London premium has now fallen back below its 2001 peak, which - based on timing alone - might ordinarily suggest that the capital was already due a renewed period of outperformance. Instead, London has continued to lag, weighed down by policy changes.
Looking ahead, near‑term growth may remain subdued. The introduction of the Renters’ Rights Act, alongside further property tax changes announced in the Budget, is likely to continue weighing on demand.
That said, while London may not reclaim its frontrunner status immediately, some of the headwinds that have held it back are beginning to ease. Falling mortgage rates should help to gradually relieve affordability pressures over the course of the year, reducing the risk of further downward pressure on prices and laying the groundwork for a more stable recovery.
