The latest data from the Office for National Statistics has crystallised a divergence that has been building in the UK housing market for months: rental growth is accelerating even as London house prices retreat, against a backdrop of inflation ticking up to 3.1%. Average UK rents rose by close to 8.7% in the year to the latest reading, while London property values fell for the first time in several quarters, down roughly 0.5% annually as affordability constraints finally bite in the capital's most stretched boroughs. This is not a contradiction but a symptom of the same underlying malaise — a housing market where ownership has become prohibitively expensive relative to incomes, forcing more households into a rental sector that simply cannot expand supply fast enough to meet demand.
