The government just published the latest Warm Homes Local Grant statistics, and they give the clearest picture yet of how fast the scheme is moving. The release, dated 27 August 2026, covers activity up to the end of July. It confirms that 5,470 households now have energy efficiency or low carbon measures installed, with 11,250 individual measures completed across England.
Homeowners, landlords, local authorities and contractors have been watching the wider Warm Homes Plan rollout closely. This release gives them the first real delivery data to measure against the scheme’s ambition. So what do the Warm Homes Local Grant statistics actually show, and what do they mean if you’re delivering or applying for funding?
Warm Homes Local Grant statistics: the headline numbers
Here’s what the official August 2026 release confirms about Warm Homes: Local Grant (WH:LG) delivery so far:
- £0.5 billion is allocated to WH:LG between April 2025 and March 2028
- 74 projects cover 271 local authorities, 97% of those eligible to take part
- 67 of the 74 grant recipients submitted data returns by the time of publication
- 5,470 households have upgrades and 11,250 measures installed, just over two measures per home on average
That last figure matters. Most households aren’t getting a single quick fix. Each home taking part receives multiple measures on average, which points toward a genuinely whole-house approach rather than one-off installations.
Where the funding is actually going
Breaking the 11,250 completed measures down by type shows what’s going into homes on the ground. Solar PV makes up 38% of installations, the single most common measure so far. Insulation follows at 24%, battery storage at 18%. The remaining share covers other low carbon heating and electricity measures, including heat pumps.
Solar and battery storage together now account for more than half of everything installed under the scheme. That’s a notable shift, because retrofit conversations usually put insulation front and centre. In practice, local authorities and contractors seem to be pairing quick, high-impact renewable measures with fabric improvements rather than treating insulation as the only priority. Expect this balance to shift as more of the 74 projects mature and submit returns.
Which regions are leading delivery
Regional delivery isn’t even, and the statistics reveal two different ways to measure progress. By sheer number of upgraded homes, the South East leads the country, accounting for 23% of all households supported so far. East of England follows at 14%.
Measure depth tells a different story, though. The North West isn’t the top region by household count, yet it has the highest average number of measures per household, at 2.33. Homes taking part there are, on average, getting deeper retrofits than homes anywhere else in the country. Local authorities elsewhere now have a real benchmark for what a well-run WH:LG project can deliver per property.
The TrustMark gap in the Warm Homes Local Grant statistics
One important caveat concerns TrustMark data. Around 14,700 WH:LG measures sat in the TrustMark data warehouse by the end of July 2026, covering roughly 6,700 households, a notably higher count than the validated figures above.
Installers can lodge work with TrustMark before a grant recipient finishes validating and linking that record for official reporting, which explains the gap. The published statistics almost certainly understate real activity on the ground. Expect future releases to revise the headline numbers upward once outstanding returns work through the system. If your own delivery already feels ahead of the national picture, this lag is very likely the reason.
What the figures mean if you’re navigating WH:LG
Local authorities have plenty of company: 271 of those eligible are already delivering WH:LG. If yours isn’t one of them yet, it’s worth asking why. Our guidance on delivering WH-LG successfully is a good starting point for the risk areas that trip projects up early on.
Homeowners and landlords can use just over two measures per household as a realistic planning benchmark, though your own retrofit assessment will determine what your property actually needs and qualifies for.

Getting the most from Warm Homes: Local Grant
These August 2026 statistics show a scheme that’s genuinely moving. Nearly every eligible local authority is involved, and real households are already benefiting, even though the official numbers still trail actual delivery on the ground. Expect the next statistical release to paint an even clearer picture as more of the 74 projects mature and the TrustMark backlog clears.
