!!!! stop not working!

Then possible lead piping up to the outside stop c0ck after that it would be copper piping so NO CHANCE of any leaks on joints or pipes splitting. As for the toilet/cistern it could be a faulty install but I would say that only a plumber can say for sure.
As I know you do worry {understandable} perhaps it would be worth getting a plumber to look at the toilet/cistern to solve the problem that way you can sleep soundly in your bed at night rather than the situation you are putting yourself in at the moment.
The cost in time/fuel running back and forth every few hours will be offset by a plumber and your stress level should return to normal :0)

No not in Kent I am sorry to say {a lovely county} . I am just glad that {from an outsiders point of view} I can point out things that because your are in the middle of it may in normal times for you not be in the forefront of your mind.
Also at my age and the number of types of jobs I had before I retired I learnt a lot of things so if I can pass them on or just set minds a little easier I can then hope I have helped a little along the way:)

Thank you so much! You've put my mind at ease !! I'm going to try figure out the toilet issue as obviously it's going to continue with the mains switched back on as it is? Bewildering x2 valves are just not holding up ?! I'm going to guess the person who installed the loo has not done it right Or the loo itself is manufactured badly I dono

Definitely stop panicking.

I just spend an age explaining what to do, then googled the valve in question and realised it's not a traditional lever arm valve.

So, I'll start again.

Take the lid off the cistern, lift the arm up on the inlet valve completely, hold it and turn the water back on. No water should enter the cistern.

If it still fills, then likelihood is new inlet valve time.

If it doesn't, drop the arm and water should start filling. Watch the float and ensure it rises without obstruction. If it's catching on something then there is (likely) your problem.
If it rises unobstructed and doesn't cut the water off before the overflow then it needs to be adjusted.

I haven't read anything on these valves but after a quick google there appears to be two types.

From photos it looks like you squeeze the metal clip that attaches the bar to the float and slide the float down, then release the clip.
OR
It's a screw shaft that you wind anti-clockwise (as you look from the top)

Your system will pressurise to mains pressure right up until it is stopped, usually at your taps. It should sit there quite happily contained.

You have mains water pressure throughout your house to every valve; whether that be a tap, shower, solenoid valve on your american fridge freezer, washing machine, dishwasher. Etc. Or even the ball !!!! on your toilet.

Not necessary true as {if there was a tank in a loft or airing type cupboard within the property} then the toilet cistern COULD be run from that tank so would not be mains pressure but a low pressure as it would be the storage tank filling the toilet cistern not the mains water.:)

Valid point, thanks given.

But, by the sounds of things, the fill valve turned to a leak as soon as the water was isolated at the stopcock, indicating mains pressure, and if it was pouring out days later I'd have expected the storage tank to be empty by then..... Unless of course there are two faulty float valves and a passing stopcock in the property :rotfl:

But I'm a spark by trade and an industrial one at that, I stay away from houses as best I can :beer:

A sparky.... That is one trade I do not touch in any way..lol. I do understand many things to do with the building business but have never been able to get my head around wiring {I can replace plugs ect but no further} so when home wiring {lights/power ect} I leave that to people like yourself, that way I live to tell the tale:rotfl:

Faulty mains stop tap not shutting off completely
Dirt on the seating or faulty washer on the syphon
Equals
Water running into the pan & the water level never getting high enough to turn off the float valve
Or it could just be a faulty float valve or not adjusted properly as MisterP said

Thanks all. I've isolated the toilet water. As when I realised water was filling up my cistern overnight with the main stop clock shut off... I figured the main !!!! stop was malfunctioning,,allowing water to still get through... Despite this, the inlet valve should still have held up and not allowed water passed into the overflow... I think the inlet valve has not been installed correctly or needs adjusted .. It's new, but sometimes stops water passing.. Sometimes doesn't ? It's playing up

If you have not got {item below link} then why not get one and cut the copper pipe leading up to the toilet cistern, that way you can isolate the water to the cistern just by turning the small screw.
I have these on ALL my taps/cisterns/ dishwasher and washing machine ect in my home so if I have a problem {ie changing a tap washeror a problem with my washing machine} I can just shut that one item off without stopping water to the rest of my place:0)
