The platform Axa Elevate, which was launched in 2009, will now provide access to five Whitechurch risk-rated portfolios.
The portfolios range from cautious – with a risk rating of four out of 10, through to aggressive – with a risk rating of eight out of 10.
Between those two there is an income strategy (5/10), balanced strategy (6/10) and growth strategy (7/10).
Axa Elevate already has partnerships with 24 other discretionary fund managers and aims to offer IFAs with a wide range of third-party portfolios in one place.
Gavin Hayes, managing director at Whitechurch Securities, said: "We continue to see an increasing demand from IFAs for our award-winning discretionary management services. It is important we can widen the distribution channels where available."
