A PropTech platform that also operates as a lettings agency has reported an increase in rental supply across Great Britain over the past year.

According to data from Dwell, there are currently 15% more rental homes available to tenants than at the same point last year. The firm analysed rental stock levels across every county in England, comparing listing volumes from December last year with the current market, to assess how supply has changed over the past 12 months.

The findings show that total available rental listings have risen from 123,669 in December last year to 142,644 this December, representing a year-on-year increase of 15.3%.

Only three counties recorded a decline in rental availability over the period: Shropshire, down 3.3%; East Riding of Yorkshire, down 4.7%; and the City of London, which saw the most significant fall at 28.5%.

In contrast, many areas have experienced substantial growth in rental supply. The largest increases were recorded in East Sussex (up 44.8%), Northamptonshire (up 42.7%), West Sussex (up 37.7%), the Isle of Wight (up 36.1%) and Cumbria (up 33.6%).

A further 21 counties saw rental stock increase by more than 20% year on year. Dwell says this points to a market that is stabilising rather than contracting, despite landlords facing higher compliance costs and increased tax pressures.

A spokesperson for Dwell commented: “It has been an exceptionally turbulent year for landlords, so many would assume rental stock would fall as investors reassess their positions. However, our analysis shows the opposite. There has been no knee-jerk withdrawal of homes from the sector and, in fact, renters now have more choice than they did at this time last year.

“This rise in available stock is a positive development for tenants and demonstrates that, despite the challenges introduced by government policy, many landlords remain committed to the rental sector.”
