A few years ago I got all the Council's accounts using the F O I Act. In that year much money was thrown out of the window including £5,000 on watering the hanging baskets on Mostyn Street. A lot of money goes on Grants to local Organisations such as the Guides, Scouts, Rugby Club and other "deserving" organisations.
A few thousand goes on Civic Sunday, a thousand or so to Town Twinning, 10K on rent to CCBC. About another 100K on Staff Salaries, Pensions etc. A few thousand on cleaning pathways and maintaining some communal areas, plus subsidising bog island conveniences. That is just some of what happens to the precept they receive.
Tessa Wildermoth will supply figures if you need them but they are published every month with the Council Minutes and are available in the Public Libraries.
