Transaction volumes in London — the number of houses being bought and sold — are at an all-time low, according to analysis of Land Registry data in three London boroughs.

The data, which was analysed by estate agents Portico, shows that there were just 55 transactions in the whole of the Westminster borough in February this year. That is the lowest ever number recorded by the Land Registry, and 60% lower than in February 2009, immediately after the last market crash.

Data from two other boroughs paints a similar picture. There were just 105 sales transactions in the south London borough of Wandsworth in February, compared to 370 the year before, a 72% year-on-year decrease.

In the east London borough of Redbridge, there were just 82 sales transactions recorded compared to 260 the year before, a 68% year-on-year decrease.

Low transaction volumes could be a bad sign. There's a very recent example of house prices falling following volume decline: The financial crash of 2008.
