its 7 days minimum and 24h symptom free. so if you still have symptoms you cant legally leave isolation as you put it.
The official advice is actually that you CAN leave self-isolation after 7 days; and you SHOULD stay home if symptomatic:

The last day of your self-isolation is whichever of these came first:
- 7 days after your symptoms started
- 7 days after you got a positive test result.
...
If you still have symptoms, we advise you to stay at home until 24 hours after they resolve.
[My emphasis]
Staying isolated until symptom free is sadly not a legal requirement - and as an example, your 7 days isolation can end 5 days after a positive test if you were symptomatic for 2 days before finally testing positive - so you're not actually required to be in isolation for 7 days post-positive testing.
One actually wonders why they bother at all, tbh...
