The Boost Initiative, run by the Community Foundation for Merseyside, wants to hear from them about trusts that are in difficulties so it can work with the Charity Commission to help them use their assets effectively.
Ineffective trusts will be encouraged to give their money more efficiently through their local community foundations. Trustees who feel their own trusts are struggling to distribute money can also make use of the scheme. The foundation hopes the scheme will unlock millions for local charities.
Cathy Elliot, assistant chief executive of the foundation, said: "The Boost Initiative offers a service to the trustees of charities that struggle to make the most of their assets. Many charities have difficulties, including the changing objectives of the charity or lack of time and resources."
The initiative will also attempt to free funds tied up in dormant charitable trusts. It will then work with local foundations to use the money to fund projects broadly in line with the original trusts' purposes.
