I had an old red dial type stopcock which didn't appear to be working, ie didn't shut off water and was visibly corroded . I replaced it with a standard stopcock but still the water doesn't turn off. I'm beginning to wonder if it is actually the main stopcock but even if it wasn't then surely it should stop the flow of water at some point. It is not under the sink but there is nothing else that it can be. The reason it is an issue is because I have a water leak of 6l/hour and Anglian water refuse to investigate unless there is a working internal stopcock. There are no damp patches or evidence of internal leaks.Any thoughts please?

You have seen your water meter still active even though you are not using water?
You have checked the loo not passing / dripping down the bowl and lifted the lid to check inside . Common issue )
Age of the home / supply pipe
Does the home have a water tank and an expansion tank, have these been checked.
Outside water tap checked.
If you have turned off the house stopcock does the cold tap still run

How old is this property?
If you mean a gate valve, they are not usually used as the main stopcock in a property, they are usually used on the low pressure side (heating and hot water).
This is a gate valve:

A one-way stopcock operates by using water pressure to tightly compress the rubber gasket. If you accidentally install it with the arrow on the valve body facing the wrong way, the water pressure will force the valve to remain open, making it impossible to shut off the water.
Ask your neighbours where their stopcocks are located.
'Fraid not - Certainly not in the UK - Our stop taps use a compression screw to push a brass rubber topped 'jumper' down onto a valve seat, it uses that compressive force to seal the rubber washer to the valve seat to stop the water flow
