New life sales at Aegon's UK business were £190m in the third quarter of 2013, a 17% rise on the corresponding period last year, thanks to auto-enrolment, group pension and platform sales.
Assets on its At Retirement Choices platform passed the £1bn mark last month.
Earnings continue to be affected by losses at its distribution units - previously consisting of national IFAs Positive Solutions and Origen - which recorded a 2013 year-to-date loss of £2m, the same as last year.
Aegon has since offloaded Positive Solutions to Intrinsic, and the group said this had already reduced its expenses considerably.
Its net income rose to £88m, thanks to a one-time tax benefit caused by the reduction in the corporate tax rate from 23% to 20%.
