Main Stop Cock Within Boundary Q

[caveman2]

I have a Essex & Suffolk mains stop cock within my front garden wall. I also have another just inside my house under floorboard. The house is 80 years old and I've owned it for the last 50.
Recently the jumper fell in my house stop cock and with advice turned it 3/4 times and the jumper restored. However I was advised it may happen again and change it. The problem is to do that I'd need to turn the water off outside and to my knowledge the garden one has never been used and assume it will be bound up. E&S tell me that it cannot be changed, be removed if I have a meter fitted.
I am in two minds as to whether I'd like a meter as I consume a lot of water with 2 gardens front and rear.
Can anyone offer an opinion as to how hard it would be for a plumber to fit another (it is only 6" inside the wall) or if with persuasion the one in situ now may still operate. Would I be right in thinking that after 50+ years it'll be unmovable?

If it's the waterboard stop cock. The one that feed yours house then they will free up or change at their cost.

As for water meter. I'm thinking of swapping. Outlaws bill was £80 for 6 months.
You can try for a year and see how it goes so no loss.
Did you read about the price of water going up to around £2000 per house buy 2035. We all need to go on a water metre. It's only a bit of stubbornness stopping us.

You may have a big garden but think about rainwater collection with a hose pump. Think about what you need to water and what you don't.

Do you know for definite it need some to be turned off outside? Also you can only assume it’s bound up.

A replacement indoors will be a messy affair if the outside one is still open. Sure, I can assume the worst. But what happens if it cracks or breaches in an attempt to open it?

Could a freeze kit be used?

If that happens, then it’ll need replacing.
