The liability that may arise under the covenant required by section 155 is a charge on the dwelling-house, taking effect as if it had been created by deed expressed to be by way of legal mortgage.
Subject to subsections (2A) and (2B), the charge has priority as follows—
The following, namely—
shall rank in priority to that charge if, and only if, the landlord by written notice served on the institution concerned gives its consent; and the landlord shall so give its consent if the purpose of the advance or further advance is an approved purpose.
The landlord may at any time by written notice served on an approved lending institution postpone the charge taking effect by virtue of this section to any advance or further advance which—
and the landlord shall serve such a notice if the purpose of the advance or further advance is an approved purpose.

The covenant required by section 155 (covenant for repayment of discount) does not, by virtue of its binding successors in title of the tenant, bind a person exercising rights under a charge having priority over the charge taking effect by virtue of this section, or a person deriving title under him; and a provision of the conveyance or grant, or of a collateral agreement is void in so far as it purports to authorise a forfeiture, or to impose a penalty or disability, in the event of any such person failing to comply with that covenant.
The approved lending institutions for the purposes of this section are—
In subsection (4) "the Relevant Authority" does not include the Regulator of Social Housing but does include the Homes and Communities Agency.
In subsection (4) "the Relevant Authority" also includes the Greater London Authority.
The approved purposes for the purposes of this section are—
Where different parts of an advance or further advance are made for different purposes, each of those parts shall be regarded as a separate advance or further advance for the purposes of this section.
