Found the process on line but when I tried to post it here I had an error message: "Your post contains too many links to external sites". If anyone wants to do a search, it was on the NALC site and referred to annual conference 2017 presentations - access to grants and funds - Shafi Kahn and Tristram Gardner.
I have also found this clear guide on a few council websites... https://www.lalc.co.uk/wp-content/uploads/2019/04/EVIDENCE-REQUIREMENT-Hints-Tips-Takeaway-Note-for-Audience-MHCLG-1.pdf
Number 6 on the checklist shows the need for a survey if there is to be an increase in the precept. It needs to be "clear and transparent, and demonstrate support for the project and how it will be funded".
Number 7 Shows the need for public support, whether or not there is a precept rise, "or at the very least, opportunities given to residents for their views, opinions, feedback on the project”.
I have had the opposite experience. 2 petitions and a Parish Poll showed opposition to the proposed site for the building work, yet it is to go ahead with no clear opportunity given to residents for their views / opinions / feedback on the loan needed to finance the project.
