The amount of funding available varies and is dependent on the amount of Grant-in-Aid (GiA) and the level of contributions from other partners. The application process is lengthy (around 18 months) and requires the Lead Local Flood Authority to submit the bid on behalf of the community with their support.

Although it is possible to achieve 100% funding, it is more likely that a lower proportion of money is achieved. The remaining costs should be met by those who would benefit from the project such as residents and businesses.
