Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what information he holds on the proportion of residential mortgage lending that was on (a) an interest-only and (b) a capital repayment basis in each year since 1997.

The Treasury does not hold any information on the proportions of interest-only mortgages and capital repayment mortgages for residential properties or buy-to-let.

The FCA in conjunction with the Bank of England publish the Mortgage Lenders and Administrators Return (MLAR) statistics quarterly. In their most recent MLAR (Quarter 1 2015) interest-only mortgages accounted for 8.61 per cent of all regulated residential mortgages.

The latest report (which has data back to 2007) can be found in the following link: www.bankofengland.co.uk/pra/Documents/regulatorydata/mlar/2015/q1longrundetailed.xls

There is no data separating the proportion of interest-only mortgages and capital repayment mortgages within buy-to-let.
