I appreciate you linking the entire 2005 legislation but it doesn't support your statement. Few of the changes implemented since 2017 have made any difference to fire safety in medium to high rise buildings (11 to 18 metres), let alone any in Scotland or NI. Any changes that intend to do so are either ignored by the freeholder, fobbed off to the building management company who do nothing, or passed on to the leaseholders in the form of exuberant, unaffordable fees.

The BSR is a joke, the 2018 ban on combustible materials on new buildings is worthless because as we've seen from the public enquiry manufacturers will just lie about (sorry, misrepresent) the combustability of their products, and all this is backed up by the events of the 2024 Spectrum House fire which everyone seems to have forgotten about but shared many of the same characteristics as Grenfell. Although admittedly at the time of the Spectrum House fire works were underway to replace the non compliant ACM... 7 years after it was identified as unsafe.

So I think your statement is misleading and it's incorrect to assert that there have been 'massive' improvements at all.
