ECO4 and the Great British Insulation Scheme - Templates to Evidence Private Domestic Premises and
Social Housing v2.0
Templates 4 and 5 must be signed by professional third parties (these are specified in the
templates). Template 7 must be counter-signed by an authorised signatory within the social
housing provider. Where possible, these templates should be printed on the headed paper of the
company signing the statement/declaration.
Where statements or declarations are used, you should ensure that all relevant parties:
• complete all sections laid out in the template, and
• sign and date the statement/declaration.
Where a statement or declaration refers to “a person”, a person includes a natural person, body
of persons corporate or unincorporated.
All templates must be completed accurately to provide evidence of private domestic premises.
Monitoring and auditing
Monitoring and auditing may be undertaken to ensure that any of the following templates used
to provide evidence of a private domestic premises status are completed in line with our
requirements.
All templates should be provided to the installer or obligated energy supplier that is promoting
the energy efficiency measure.
Completed templates may contain personal information, therefore, sending these forms to other
parties will amount to the processing of personal data as detailed in the Data Protection Act 1998
(DPA). These forms must not be sent to Ofgem directly unless requested for auditing purposes.
Any evidence of electronically duplicated or forged signatures will be investigated. Any measures where
suspected fraudulent activity or scheme abuse is detected will be rejected
