Where are you living and why do you think it isn’t working
Buckinghamshire, and I don't "think" its not working, I can see its not working with my own eyes.
The majority are doing as asked, but I'd say up to 10% aren't, I actually think that some believe they are doing as asked, but they're clearly not.
Examples, and I've barely been out....other than sit on our balcony in the sunshine.
A neighbour opposite has had 2 separate families with kids visit their flat this weekend.
An older couple in a neighbouring block have had their daughter and granddaughter visit every day since it began.
There's groups of teenagers wandering around the complex, clearly not from the same household.
Teenagers are congregating in every green space available according to the local police, dispersing when they turn up, and gathering again as soon as they leave, they've had over 200 calls in 2 days.
There's parents who seem to have sent out their younger kids to play on this complex, some seem to be out most of the day, and most of these kids I've never seen before the restrictions were put in place, and I'm around a lot as I work part time.
A couple in our block have been out 5 or 6 times a day in their car for the last week (its a modified large Audi, so its hard to not notice when he fires it up), he's just been out for 3 minutes in his car, came back with 4 cans of something, the only shop he could have visited is 2 minutes walk away. (I have to use the same lift/stairwell as they use, I'm avoiding the lift, and touching nothing else unless I absolutely have to.)
