The Bourne Estate Leaseholders’ Group has had progress with challening its major works bill;
So far we got together as a group, each wrote a payment under protest letter and now the council has allowed us to enter ADR (as a group) before we take it to First-tier Tribunal.
It seems the ADR process is not advised by the council much. You should ask about ADR if you are not getting anywhere and before taking the council to First-tier Tribunal.
