Where a local authority have incurred expenses for the repayment of which the owner of the premises in respect of which the expenses were incurred is liable, either under this Act or under any enactment repealed thereby, or by agreement with the authority, those expenses, together with interest from the date of service of a demand for the expenses, may be recovered by the authority from the person who is the owner of the premises at the date when the works are completed, or, if he has ceased to be the owner of the premises before the date when a demand for the expenses is served, either from him or from the person who is the owner at the date when the demand is served, and, as from the date of the completion of the works, the expenses and interest accrued due thereon shall, until recovered, be a charge on the premises and on all estates and interests therein.
The rate of interest chargeable under subsection (1) or subsection (2) of this section shall be such reasonable rate as the authority may determine:
A local authority shall, for the purpose of enforcing a charge under this section, have all the same powers and remedies under the Law of Property Act 1925, and otherwise as if they were mortgages by deed having powers of sale and lease, of accepting surrenders of leases and of appointing a receiver.
