He will replace Andrew Gillespie who has left personal reasons, according to a spokeswoman. It is not known whether he has a job to go to.
Kelsall has been working as a consultant at Standard Life since September.
He has previously held senior marketing roles at Experian and Barclays, where he held the position of commercial director for retail banking.
Gillespie, a former group marketing director at Barclays, joined in October 2008.
Standard Life completed a restructure of its UK marketing team last May. The restructure involved the separation of marketing and product development and is to lead to the creation and abolition of a number of roles.
Earlier today (20 January), Standard Life’s Assurance business was fined £2.45m by the Financial Services Authority for “misleading” marketing.
