As of July last year there were 2,107 council owned tower blocks (10 storeys or above) in the UK.
Not sure how many private or Housing Association tower blocks - but probably at least the same again.
Of the council blocks, 112 had a sprinkler system fitted - almost certainly a higher % than for non-council blocks - 10 years after the Lakanal House fire that killed 6 people and the lessons of which were ignored by the coalition government of 2010 (sacrificed to 'austerity'), and led directly to Grenfell.
