Skandia clients will now be able to link their assets to those of their spouse or civil partner in order to potentially qualify for a lower platform charge.
Skandia previously calculated the platform charge based on the total value of assets held on an individual basis.
The introduction of client linking means that the platform rate will be calculated based on the combined value of the assets held by both the client and their spouse or civil partner.
Skandia platform marketing manager Mike Barrett said: "This enhancement to the Skandia Investment Solutions platform will allow spouses or civil partners to benefit from a reduced platform charge, reflecting their total combined assets.
"Advisers have been telling us that they will often look to manage such investments holistically, so it's great to be able to respond to feedback and deliver an improvement that will directly benefit their clients."
