Paul Smee, director general of the CML, commented:
"House purchase lending in London fell in 2015 due mainly to a slow start: later months of the year saw activity pick up again. Persisting supply and affordability issues, alongside the introduction of the Help to Buy London scheme, means there will be some uncertainty around how the market will perform going into 2016.
"By contrast, remortgage activity, which has been consistently flat for the past few years, appears to be on an upward trend. Competitive mortgage rates appear to have sparked this activity and we have not seen quarterly volumes at this level since 2009."
