@EYProvider I'm guessing you probably didn't grow up in the north east or Scotland, if you don't remember the 1970s being bitterly cold!
We didn't have central heating either (still don't although I'm in a different part of the country now and we do have decent oil-filled movable heaters, plus heavy curtains at windows and doors, plus dehumidifiers, plus fake Ooodies, plus lots of other combatting the cold techniques) but I remember waking up to see my breath in the air in the bedroom, and ice angels on the inside of the window panes, with the curtains stuck to them. Only one room was ever warm when I was growing up, the living room, and I'm sure the fact that our flat was icy cold, contributing to the black mould in all the rooms at the back (housing association flat) helped hasten my dad's death long before his time (respiratory issues).
In answer to the original question, though, yes, it might be possible to use public buildings like libraries - if the Tories and the Coalition hadn't mounted a never-ending attack on such public amenities via the ever-increasing attacks on the meagre funds that trickle down to local councils.
This is especially apparent in poorer areas like the one where I grew up, which is why the "Levelling Up" nonsense just makes me snort in derision. Still, as long as they can prove how incredibly in touch they are with the peasants by the likes of Andy Haldane spouting forth about Renaissance Florence, what's not to like?!
In case anyone would like a bit of evidence to support that first statement about how rich areas are doing much better than poorer areas out of "Levelling Up", thanks, there's an outline at www.theguardian.com/inequality/2022/feb/02/levelling-up-funding-inequality-exposed-by-guardian-research. Money goes to money still, it seems.
As others have said, libraries (and swimming baths, and parks, and community centres, and lots of other public service locations) are a dead easy target when it comes to cost cutting. The rich are just fine with their latest release Kindles, private gym memberships, walled gardens, National Trust memberships, and country clubs...
