Part 11: Energy Savings Opportunity Schemes Section 257: Assessors
This section enables regulations to set out functions and powers relating to assessors (see section 256) and also to bodies responsible for maintaining list or register of individuals who may be appointed as ESOS assessors.
	Subsections (2) and (3) enable regulations relating to the appointment of assessors, including powers to require that they must be of a specified description which may refer to any criteria, for example competence, or membership of a designated list, body or scheme.
	Designation for these purposes must be either by the Secretary of State or scheme administrator (subsection (4)) and subsection (6) enables regulations relevant to this, including provisions relating to powers to give, review and remove those designations and to publish a list of them.
	Subsections (7) and (8) enable regulations to provide for a designated body, scheme administrator or the Secretary of State to maintain lists or registers of persons who may, or who may not, be appointed as assessors (for example assessors who have been removed from a designated register for poor practice).
	ESOS regulations under subsection (9) may authorise a scheme administrator to share specified information with designated bodies, for the purpose of ensuring that assessors still meet relevant criteria or to ensure the quality of ESOS assessments.
	ESOS regulations under subsection (10) may enable the Secretary of State or a scheme administrator to give directions about a list or register to a person responsible for maintaining that list or register, and to require compliance with those directions.
