Assessors shall decline any suggestion from the owner/occupier to enter neighbouring properties.

 3.8.1 Members may come across personal information about the various parties, in particular the owner, occupier/s and owner/occupier of the Property, which has no relevance to the Report.

Code of Conduct Addendum 1

Specific requirements on Energy Assessors during a public health emergency

Energy Assessors are in a privileged position to be able to access and assess properties, however during public health emergencies, such as Covid, Energy Assessors must follow strict protocols to protect themselves, occupants, or any other property professional they interact with.

A1.1 Energy Assessors shall follow the public health guidance issued by the Government.

A1.2 Energy Assessors shall notify clients on the steps they will be undertaking to ensure protection for all during an assessment.

A1.3 Energy Assessors shall take necessary steps to protect themselves and others which include, but are not limited to:

A1.3a Correct use of personal protective equipment (face mask over nose/mouth; disposable gloves);

A1.3b Follow hand cleaning or sanitising protocols;

A1.3c Allow sufficient space between you and any persons present during assessments;

A1.3d Where possible, request any persons present to leave the property during the period of assessment;

A1.3e Ensure properties are sufficiently ventilated when completing assessment.

A1.4 Where an Energy Assessor attends a property where a person present is under Government instruction to shield or self-isolate as a result of the health emergency, the Energy Assessor shall arrange to complete the assessment at another time.

A1.5 Where an Energy Assessor is suspected of breaching these requirements, the Scheme shall consider this to be a major transgression in the obligations of the Energy Assessor, and the Energy Assessor will have their accreditation suspended until the matter is investigated and resolved.

A1.6 Where an Energy Assessor has further instances of breaching these requirements, they risk bringing the Scheme and the industry into disrepute; the Scheme may sanction this behaviour with a permanent revocation of accreditation (strike off).
