First, set up a committee of:
a/ A member of the Highways dept.
b/ A representative of Open Reach
c/ A representative of Transco
d/ A representative of the National Grid
d/ A politician or three.
e/ A few local councillors
Get them to discuss, at length, any works which are to be done in each of several thousand different areas of Britain.
Pay each representative a reasonable wage.
There will then be no agreement over what order work is to be done, or any money to pay for it.
Therefore no roads will be dug up. Job done!
