Scottish Provident will only be offering four-year earnings commission basis from August 1, the firm has announced.
It says the reason behind the move is that it will allow the firm to invest further in its proposition by adding more features for IFAs, as well as creating choice and competitive pricing.
Bright Grey will continue to offer a choice of two or four years for personal protection menu business.
The move follows other changes at the two firms over the past three months, including new critical illness cover definitions.
Roger Edwards, proposition director at Scottish Provident, says: “Throughout this process we’ve not shied away from the big decisions, and every change has had a key requirement at its heart: to dovetail seamlessly and to build a stronger more potent business whilst maintaining the interests of the individual brands.
“Whilst all around us competitors are consolidating their brands and reducing the choice available to advisers, Bright Grey and Scottish Provident are keeping separate brands and continue to go from strength to strength.”
