West Berks publishes the per-capita parish precept for all of the parishes in West Berkshire, and I've ordered the list by that per-capita charge.
If you were interested in where a parish was spending your money the first thing you'd need to see is the council's budget. This details what the council spends on what services and from this you can make an informed comparison with the costs of other parishes and judge how efficiently you parish is spending your money.
I find it pretty shocking then that parish councils are in general very poor are making their financial details available. I looked for the council budgets for the top 17 parishes by per-capita charge and I only found the budget on three of those web sites: Newbury, Shaw-cwm-Donnington, and Stratfield Mortimer (and if I missed any then I apologise, but I did have a good rummage).
In principle you could get the budget with a Freedom of Information request, but that is not without its problems, not least that a defensive council might make a bit of a song-and-dance of the request and not take kindly to your unwelcome interest. The Freedom of Information Act places a general duty on public authorities to make their information publicly available, and the spirit of the act is that public authorities should publish useful information about themselves without being asked.
On this showing the parishes in West Berkshire are in general not encouraging their parishioners to take an interest in their financial details, and it's a reasonable guess that parishioners are indeed not at all interested, and that is not a healthy state of affairs.
Here's the list of parishes by per-capita precept charge.
