Does anyone else know about this & what the rationale was at the time? I can't believe they got away with it. I've recently started helping a friend refurbish flats and we're now on our 3rd flat (all in purpose built blocks) that has no provision for heating, I just don't understand it. It's not like they're old enough to have had open fireplaces to heat the place, there's nothing at all! The floors are solid concrete, the outer walls brick and the inner dividing walls are studwork on battens. In each case we've stripped back to the bare bones and there's no evidence of previous surface mounted pipework, nor anything buried. The blocks were all built in the 80s, one of 12 flats (4 stories high) & two of 18 respectively (6 stories). Privately owned I should add. Did developers routinely not put central heating in back then & you'd 'choose' to have it fitted? I just don't get it. It goes without saying that there were damp issues in each of these flats. I should add there were no grills nor provision for a hot air system either. I'm flummoxed.
