Putting to one side whether or not it's really ok for a minister to chastise leaseholders in buildings with dangerous cladding for being sarcastic, the government's testing regime does not in fact justify this statement https://twitter.com/team_greenhalgh/status/1326915532839378946
After Grenfell the government charged ahead (against independent advice) with a programme that only tested ACM (the product used on Grenfell) cladding systems, and then set about trying to remediate them. Here's a couple of views from insiders:
They promised to test other materials but it wasn't until almost two years later that we saw any. And this was a test of the safest form of HPL available paired with non-combustible insulation. It narrowly passed but not without criticism https://www.insidehousing.co.uk/news/news/hpl-test-criticised-by-organisation-that-carried-it-out-62411
Roll on another nine months and a private test of a more widely used HPL system (arranged by @Jonatha135113) saw it fail almost as badly as the worst ACM system the government had tested: https://www.insidehousing.co.uk/news/news/widely-used-hpl-cladding-system-dramatically-fails-official-fire-test-65870
Then finally we got some data on govt testing of other materials, which they said justified the ACM focus. But it was partial. The most dangerous materials (untreated timber, HPL) - were subjected to small tests which concluded there was 'lower peak heat release'
We also didn't see any tests on polyethylene cored zinc - which might have been worse than ACM - because the govt couldn't procure any. And all the comparisons were with the most combustible form of ACM, which doesn't reflect the remediation programme.
In summary - there's no justification for saying that a 20m building with a small amount of category 2 ACM should be remediated before a 50m tower with ground to roof HPL. Just insisting ACM is worse is in no sense a proper prioritisation of risk.
I'd also gently suggest that having less than half the identified towers complete three and a half years after Grenfell despite ACM being the sole focus of govt efforts for much of that time is no cause to slap down people who respond sarastically (ends)
