Cost of 20 mph road signs

The authority would like to / has responded by post to this request.

Dear Hart District Council,

Councillor Wheale claims that the cost of putting up the 20 MPH
speed signs was nothing for Hart but provided free by the
Government.
This is a nonsense as the government has no money of its own and
uses tax payer's money for any project.
Therefore taxpayers had to pay for these road signs.
How much has it cost the taxpayer?

Yours faithfully,

R. G. Smith
