Section 63 defines "residential landlord" for the purposes of the private rented sector database and the landlord redress scheme sections in Part 2. Subsections (4)(b) and (6) of section 63 enable the Secretary of State to make the landlord under tenancies of dwellings occupied for the purposes of either House of Parliament (that are periodic or granted for a term less than 21 years), or under licences to occupy such dwellings, a "residential landlord" and therefore subject to the requirements imposed on landlords by Part 2.
	Subsection (1)(a), (b) and (c) provide that the offences relating to landlord redress schemes and the private rented sector database will not apply to tenancies or licences of dwellings occupied for the purposes of either House of Parliament if such tenancies or licences become subject to Part 2. Relevant persons who breached the regulations in those circumstances would nonetheless still be liable to receive financial penalties as provided for in sections 66 and 91.
	Chapter 3 of Part 1 (Discrimination relating to children or benefits status: England) does not apply in relation to premises that are occupied for the purposes of either House of Parliament and nor do various sections within Chapter 3 of Part 4 (Investigatory powers).
