Yes, she'll need to be able to prove how she has spent every penny of the grant funding to TNL. The fact the money has been provided for a pilot suggests that there might be an option to extend funding if it is successful, and so she'll need to provide robust evidence of success, to prove they have met the outcomes and targets set out in their application.If they've said for their grant that they've got a DV angle they'll have to prove that. I really hope the regional National Lottery manager who she'll be dealing with can see through what is going on. Funders talk to each other and there is a list that funders can access of people who they've funded and I think from memory it states whether they've been given continuation funding or not. If TNL didn't give continuation funding that could possibly impact getting further funds (if the reason for not giving continuation funding is visible - again, can't remember, I'm really struggling this morning).
I really hope they don't have a hun for a grant manager
Also! It depends exactly what they've put on the form for how they've said they'll achieve their aims... but she can't deviate from that, she has to do what she's said or get permission to use the money in a different way. She'll have to prove she's done what she says she has with the money she's been given
If they aren't successful in any future application for TNL funding, either because the pilit project failed or even because the application process is too competitive (there is nowhere near enough money to go round) and they look elsewhere for funds, due diligence checks will show previous grants which have been given to them and what those grants were for. If I remember correctly, she'd have to disclose that on applications as well, and again provide proof of outcomes of previous projects etc.
