Commentary on Sections Part 4: Standards of Housing Chapter 2: Suitability for Numbers in Occupation Section 53: Statement of remedial work
Section 53 sets out that a statement of remedial work is a statement of work which the owner of the HMO may undertake and which, if done, will lead to the lifting of the suitability notice.  Although the owner is not required to carry out the work, they can choose to do so as an alternative to having the restriction on occupancy imposed by the suitability notice.
