An interesting map of London ALMOs in 2009 and 2017 was published in Brent Council's last full Council agenda. One can see at a glance that most of London had adopted ALMOs by 2009, but abandoned them later on.
The reason is money.
As I have explained before, the previous Labour government offered Councils lots of money to do up their Council housing if they agreed to an ALMO arrangement. By 2017, this incentive had long since disappeared so the Councils just started taking the properties back in house. It does show some of the demerits of that kind of policy making.
