The decision to branch out into campaigning was prompted by a consultation with the fund's 240,000 beneficiaries. The charity wants to recruit a seasoned campaigner to head a new team.
A spokesman said: "Our beneficiaries want us to have more of a campaigning presence. We will be lobbying for their beliefs, rather than their rights."
The charity's first new campaign will focus on ensuring that local authorities install fire sprinklers in all schools that undergo refurbishment.
It also plans to launch a high-profile campaign about attacks on firefighters.
