This section provides the Secretary of State with powers to introduce regulations adapting other legislation and private legal instruments to changes made by Part 1 Chapter 1 of the Act (Tenancy Reform: Assured Tenancies) or its associated regulations.
	Subsections (1) and (2) provide that the Secretary of State may introduce regulations to amend existing legislation so that it continues to operate in a way that is similar or correspondent to its effect on tenancies prior to key changes the Act makes to the assured tenancy system. This applies to (i) provisions relating to fixed term tenancies and assured shorthold tenancies which section 1 converts to assured periodic tenancies, so that those provisions can be adapted to cover assured periodic tenancies in future; and (ii) provisions relating to the grounds of possession in Schedule 2 Housing Act 1988, which are altered by section 4 and Schedule 1.
	Subsection (3) provides that regulations in relation to assured shorthold tenancies made under subsection 1(b) can include measures to ensure provisions relating to notices served under section 21 of the Housing Act 1988 continue to apply in relation to notices under section 8 of the same.
	Subsection (4) provides that transitional provisions that may be included in regulations made under the powers in subsection (1) or (2) include provision modifying the effect of existing private legal instruments which the Secretary of State considers will not operate appropriately. Private legal instruments may include insurance contracts, leases, or mortgages. Subsection (5) clarifies that this includes where a provision made by the instrument is redundant, unclear or outdated following changes to the law, or where the Act might put a party to an existing agreement in breach of terms it currently complies with.
	Subsection (6) ensures that, when regulations under subsection (4) change the effect of private legal instruments made before the Act’s changes, the parties to those documents can agree a different result instead of the default one provided by legislation.
	Subsection (7) provides that regulations made under subsection (4) may apply to an instrument as it had effect before the coming into force of the regulations but after the commencement date.
