Section 333 of the [1936 c. 49.] Public Health Act 1936 applies in relation to local authorities acting under this Act as it applies in relation to local authorities acting under that Act.

Nothing in this Act about the recovery of expenses from owners of premises affects the [1975 c. 76.] Local Land Charges Act 1975.

All powers and duties conferred or imposed by this Act are in addition to, and not in derogation of, any other powers and duties conferred or imposed by Act, law or custom, and, subject to any express provision of this Act, all such other powers and duties may be exercised and shall be performed in the same manner as if this Act had not been passed.

This Part has effect subject to paragraph 13 of Schedule 3 to this Act.
