Though not the most expensive, Essex had recorded the most dramatic price increase since 1999 with a 371% rise. Prices in this county had risen from an average of £75,885 to £357,039.

CapitalRise commented that a move towards flexible working in recent years had added to the Home Counties’ attractiveness to homebuyers, especially those in London.

“One factor driving the trend is the natural constraint on supply in relation to the high demand within the prime central London property market,” added Uma Rajah, CEO and co-founder at CapitalRise.

“As such, the Home Counties also offer plenty of opportunities for ambitious developers looking to deliver high-end property in the South East. Combined with moves towards more flexible working arrangements, this has also made relocating to the commuter belt more attractive for many professionals working in London, increasing demand for property in these key areas.”
