Is this a stopcock in airing cupboard?

[Last Plumber]

Had no effect on the flow, I don't know where the external stop tap is, there is one toilet sewage at the side of the home, and three different metal lids in the back garden, I have never looked to see what they are.

Would it be safe to clamp down the washing machine pipe to change over to the newer machine?

I don't know, I have never clamped a pipe inside a property.
Is there no isolation valve on the washing machine hose?
The external stop tap cover would normally be 4"-6" kind of size.

Unusual!
It could do with one.

Sounds like a job for your local Plumber.

I've just looked at the back of the washing machine and saw a screw on the isolation valve?

Unfortunately I turned this stopcock clockwise and also anti-clockwise and it made to difference to turning off the water.

Did you fully turn it until it stopped eg clockwise ?
