Under ECO3, energy suppliers will be able to deliver up to 10% of their obligation through the installation of innovative measures to eligible households. There are two innovation routes under the scheme:

  • Demonstration actions – measures that have previously been tested in a laboratory setting and now require testing at scale in a live environment, or are marketable products that are being sold in the market and may need additional support.
  • Innovation measures – a measure that is different from those previously delivered under supplier energy efficiency obligations by having, for example, an improved material that can demonstrate improved energy efficiency performance, or an improved installation technique.

These routes are optional and energy suppliers do not have to deliver measures under them. However, to encourage participation by obligated suppliers, and to deliver new and improved measures into the scheme, a Lifetime Bill Saving score (for demonstration actions) or a deemed score uplift (for innovation measures) will be awarded to measures that are delivered under these routes.

In addition to innovation, suppliers will be able to use a new monitored measures route to deliver up to 10% of their obligation. This is also voluntary and is intended to allow suppliers the opportunity to use modern monitoring technology to measure the actual energy efficiency performance of homes that have received energy efficiency measures over time. Suppliers who use the monitored measures route will receive a score uplift if the measures that are being monitored are proven to deliver more savings than that assumed by the standard deemed score.

We have written guidance to assist interested parties in delivering measures under these three routes. This can be found below, alongside the 3 application forms for each of the innovation routes. Approved innovation measure descriptions and monitored measure scoring methodologies are also published below.

Please note that only obligated suppliers can submit an innovation application to Ofgem.

A technical advisory panel (TAP) has been set up to review applications made under each route and make recommendations to Ofgem to approve or reject applications. Minutes of TAP meetings will also be published here. The TAP meeting dates for 2019 are as follows:

  • 3 April 2019 (application deadline of 6 March) - Minutes available
  • 15 and 31 July 2019 (application deadline of 17 June) - Minutes available
  • 7 October 2019 (application deadline of 9 September)

The TAP meeting dates for 2020 are as follows:

  • 5 February 2020 (application deadline of 8 January)
  • 28 April 2020 (application deadline of 27 March)
  • 28 July 2020 (application deadline of 30 June)
  • 27 October 2020 (application deadline of 29 September)

Before progressing an application under one of the innovation routes, interested parties should first assess whether the measures they are proposing have already been delivered under the scheme, as only measures which are materially different can be supported. They should consult our public reports to understand what has already been installed under ECO. They should also assess whether it is the most suitable route to deliver the new or improved measure under the scheme. Suppliers can still make an alternative methodology application to apply for a new scoring methodology. We recommend that interested parties consult the decision tree below to determine what type of application may be suitable for the measures in question.
