Paragraph 12 Construction hours
Construction works relating to the authorised development must not take place on Sundays, bank holidays nor otherwise outside the hours of 0800 to 2000 hours on Monday to Saturday (with the option of 0700 to 1900).
The restrictions in sub-paragraph (1) do not apply to construction works where these—
are carried out within existing buildings or buildings constructed as part of the authorised development;
are carried out with the prior approval of the relevant planning authority;
are associated with an emergency; or
are associated with slip form working.
In this requirement “emergency” means a situation where, if the relevant action is not taken, there will be adverse health, safety, security or environmental consequences that in the reasonable opinion of the undertaker would outweigh the adverse effects to the public (whether individual classes or generally as the case may be) of taking that action.
