The Tories seem up in arms about the prospect of new valuations for council tax...

Tories warn over home inspections:

MPs are discussing new powers for inspectors in Northern Ireland, as part of the revaluation of its rates system.

It could pave the way for English tax payers to be forced to admit inspectors who want to check features which could increase house values, the Tories say.

Of course, if they simply changed over to taxing land values nobody would ever have to even open the garden gate.
