Household Energy Efficiency Headline Release (quarterly data)

source

This is a pre-announcement of a forthcoming statistical release: the quarterly Household Energy Efficiency Headline statistics covering ECO and the Green Deal Framework will be published on 28 May 2026 at 9:30am. It contains no data, only the confirmed release date. The underlying statistics track insulation and heating measures installed under supplier-funded efficiency obligations.

Nothing changes here; this is an announcement of an announcement. ECO is a supplier obligation that redistributes the cost of efficiency measures across the bill base rather than altering market structure, generation, or what can be built or connected.
