This page provides details of the standardised templates produced by the ECO Reporting Working Group in order to streamline the reporting process for the supply chain.

The documents published on this page relate to measures installed from 1 April 2017 onwards. The documents have been revised in light of the new scheme requirements being introduced on 1 April 2017. The previous versions of these documents relating to measures installed between 1 April 2015 and 31 March 2017 can be found on our website

You can access the the following standardised reporting templates at the bottom of this page:

ECO2t Landlord or Management Company Permission - designed to help landlord and management companies give their consent for installing ECO measure(s).

ECO2t Landlord or Management Company Permission – multiple premises spreadsheet - designed for use alongside the Landlord or Management Company Permission form where it refers to multiple premises.

ECO2t Consent Statement and Privacy Notice – this document outlines the ways in which a consumers personal data may be processed and who it will be disclosed to. This document allows the consumer to sign to confirm that they are content with their data being shared with the parties listed.

ECO2t Declaration of Conformity and Completed Installation - this document enables the customer and installer to sign for the handover of the measure, and make a declaration against a range of energy company requirements. Ofgem has reviewed this and is satisfied that it meets our requirements for (i) handover to customer; (ii) the PAS declaration of conformity; (iii) the declaration of completed installation; (iv) the reason why 100 percent of a measure was not installed; and (v) confirmation that the premises was built before 1 April 2017 or was occupied before the measure was installed.

ECO2t Help to heat group and private domestic premises checklist - designed to help installers identify whether a measure meets the relevant help to heat group and private domestic premises requirements.

ECO2t Room-in-roof checklist - designed to assist installers in recording the pre and post installation details of a room-in-roof insulation measure, and to determine the associated percentage of measure installed (POMI) and percentage of property treated (POPT) for the measure.

ECO2t Deemed Scores Survey - designed to assist installers in identifying the inputs that should be used to select the correct deemed score for a measure.

ECO2t Digital software guidelines –  this document provides best practice guidelines for installers and suppliers using digital or electronic software for the administration of ECO measures.

Amendments – 10th November 2017

ECO2t Landlord or Management Company Permission - The measure types have been updated to match those of ECO2t and they are now listed in alphabetical order. The signatory’s job title/position has also been added to the document.

ECO2t Consent Statement and Privacy Notice – additional information was included on how a customer’s data may be processed.

ECO2t Declaration of Conformity and Completed Installation - The customer declaration has been moved to the first page as a stand-alone item and there have been additional inputs added to the measure section table in relation to heating controls. A measure installation declaration has been added to be completed by an installer where POMI is <100%.

ECO2t Room-in-roof checklist - We have detached the residual areas row from the main table to assist the supply chain in the more efficient completion of the table. We have also added a N/A option for situations where a room-in-roof does not have a residual area.

Amendments – 14th December 2017

ECO2t Declaration of Conformity and Completed Installation - This document was republished on 14/12/2017 to correct a minor text error for Gas boiler replacement in the measures section table. The date and version number were unaffected.

Amendments – 1st February 2018

ECO2t Deemed Scores Survey - This document was republished on 01/02/2018 to reflect a change in the notification of the Percentage of Property Treated (POPT) from 10% increments to 20% increments. This change came into effect for measures installed from 01/02/2018. There have also been some small changes to the overall usability of the document as recommended and agreed upon by the ECO Reporting Working Group.

Amendments – 24th May 2018

ECO2t Privacy Notice – This document outlines the ways in which a consumer’s personal data may be processed and who it will be disclosed to. It has been updated in line with the GDPR.

Where a supplier or member of the supply chain is a controller for the purposes of the GDPR, it is their responsibility to ensure that their processing of any ECO-related data is compliant with the new regime. If they process or share data that is not covered by the Privacy Notice, they must provide separate information on this. The Privacy Notice does not cover the processing of special categories of data (including the processing of data related to disability benefit). 

Suppliers are required to ensure that the following wording is in a privacy notice handed to consumers:

“The Office of Gas and Electricity Markets (Ofgem) will:

  • use and share your information in order to fulfil its statutory duties;
  • if requested, share your information with the installer of the measure in order to verify whether it has been notified to Ofgem;
  • if necessary, share your information with auditors contracted to ensure the integrity of the scheme.
  • when required, disclose your personal information to the Secretary of State of the Department of Business, Energy and Industrial Strategy. They may use some of the data for research and statistical purposes and may, for these purposes, link the data with other data sources they hold.

To find out more about how Ofgem processes your information, refer to their privacy policy available online:”
