ECO2t Help to heat group guidance note


Publication date

Scheme name


This document aims to assist suppliers and the supply chain in evidencing help to heat group (HTHG) eligibility. It shows the requirements for the HTHG eligibility routes, and which parts of each benefit letter can be used as evidence of eligibility.

HTHG eligibility is specified in the ECO2 Order as amended by the Electricity and Gas (Energy Company Obligation) (Amendment) Order 2017 (called the ECO2 Order in further references).

We show some ways of proving HTHG eligibility, however the scenarios are not exhaustive.

It is a supplier’s responsibility to ensure that documents submitted to us as evidence of eligibility are in line with the requirements of the ECO2 Order and the ECO2t Guidance: Delivery.

This guidance note, and any references to ECO eligibility, are only relevant for measures installed from 1 April 2017. For measures installed prior to this date please refer to our Affordable Warmth Group guidance note
