The slide by the numbers
Prime London values are roughly 27% beneath their 2014 peak, according to Savills' index. A Bloomberg News analysis comparing those figures with the consumer price index puts the inflation-adjusted decline at more than 49%. If values simply tread water and inflation persists at today's pace, prices are set to be 50% below the 2014 level in the early months of next year. Savills' latest forecasts do not see nominal gains returning until 2028.
What knocked the market off course
The downturn began after then Chancellor of the Exchequer George Osborne introduced multiple reforms in 2014 that significantly raised transaction taxes on the highest-priced homes. Successive chancellors added surcharges for landlords and second home owners, for overseas buyers, and for purchases made through companies instead of in personal names. Brexit, the pandemic, rising wealth taxes, and questions over London's standing as a magnet for the super rich piled on, deepening the slump in trophy-home values.
Savills' index, which dates to 1979 and mirrors price moves in the most coveted districts, follows a period of exceptional post-financial-crisis growth. Over the 35 years prior to this correction, price gains averaged about 5% above inflation, Lucian Cook said.

The dollar lens and a real-world comp
For American buyers, currency shifts magnify the drop. The 27% slide in the index translates to about a 40% nominal decline in dollar terms, or 58% after US inflation. "It means it is looking very good value," Cook said. "There probably isn't the stimulus for a recovery," Cook said. "That long awaited recovery is held back not just by circumstances but by stamp duty."
What this means for your portfolio
High-end London property looks like a patience game. With nominal growth not expected until 2028, inflation and currency can overwhelm headline prices, making the same home look very different depending on your yardstick. If you watch from abroad, the pound and local inflation may matter as much as the asking price.
