This is typical seasonal activity between September and October - the average monthly rise over the last decade has been 5%.
According to the CML, the annual comparison should start to improve a little in the coming months as underlying lending volumes dropped sharply in the latter part of 2008 and early 2009.
The October outcome is in line with the CML’s updated forecast for gross lending of around £141 billion for 2009 as a whole. It expects some seasonal slowdown over the remainder of this year.
Commenting, CML economist Paul Samter observed: "There has been a significant change in the type of lending taking place from the start of the year. House purchase activity has picked up significantly. In contrast, remortgaging has dropped to decade-low levels as many borrowers have little incentive to refinance when they move onto low reversion rates, and others find themselves unable to do so due to equity constraints.
"The coming months are likely to be dominated by seasonal factors rather than underlying change."
