were estimated by the occupancy model to have an occupancy rate of over 90 nights in
the year, as at May 2019. 50% of the listings estimated to be occupied for over 90
nights were in just five Inner London boroughs: Camden, Kensington and Chelsea,
Southwark, Tower Hamlets and Westminster.
8.9. With the average price of an Airbnb stay at £109 per night, the potential revenue from
short-term lettings is greater than from an open market rent tenancy, creating a
financial incentive for hosts to exceed the 90-night limit. Until there is appropriate
regulation of short-term lettings in London, this activity is likely to continue to grow.
8.10. The occupancy model makes assumptions about the review rate, length of stay and
occupancy rate, to provide a modelled estimate of the occupancy of an Airbnb listing.
As such, the model cannot provide definitive evidence of the occupancy of short-term
lettings in London. Actual operational data is not available on the number of nights that
properties listed on Airbnb (and other home sharing platforms) are occupied.
8.11. Data obtained from the London Borough of Camden suggests the extent of short-term
letting is far greater than can be determined using Inside Airbnb data alone. When data
from multiple platforms is combined, a high proportion of the homes monitored were
unavailable for the entire 90 nights monitored.
8.12. Local authorities are tasked with planning enforcement in their boroughs, but they have
struggled to monitor and enforce against unlawful short-term letting practice. This is
partly due to a lack of resource and is compounded by a lack of available data. Local
authorities must be adequately resourced and supported to ensure they are able to
properly enforce the provisions of the Deregulation Act 2015, to hold hosts to account
where they are in breach of the 90-day rule or otherwise do not act in accordance with
the regulatory requirements governing short-term letting in the UK.
8.13. Some platforms have implemented caps on bookings in London above 90 nights.
However, caps on individual platforms alone are not enough. Clear and co-ordinated
data on short-term letting, over time and across platforms, is needed to fully
understand the extent of home sharing in London.
8.14. The Mayor announced his support for a statutory registration system in April 2019.
Alongside London Councils and Airbnb, the Mayor is calling on Government to
introduce a statutory registration system for short-term lettings in London. This system
would require hosts to register their property before renting it and would give councils a
more effective means of monitoring short-term letting within their borough.
8.15. Further ways to support borough enforcement activities could include providing clarity
on the planning laws governing the Use Class of short-term letting; increasing
awareness of the 90-night limit and associated legal obligations for hosts; implementing
caps on individual home sharing platforms; and supporting boroughs’ internal and pan-
London engagement.
