I wouldn't like to say what is the norm. Certainly there are exceptions to this. Despite pressures, the council of which I'm a member has progressively reduced its precept over the years since 2010, taking account citizens' ability to pay. That isn't always possible, but certainly councils should do everything they can to provide good value.
It is difficult to ask for personal details, but there must be questions about costs that can be asked and expect an answer. Beyond that, it is the usual answer: citizen pressure and the availability of alternative councillors is ultimately the only way to bring about change.
