water supply for barn conversion

[LSB]

We are in the middle of converting our barn and are using water from our house for now.

 

I thought I should get on and look at a supply, but when I try and select where I want the water supply I get this

 

 

This is about 3 ft from the mains supply for our house.

 

Does anyone know what this means, 

 

In these post-covid days these companies don't have telephone numbers to call with questions.

 

This is Anglian water.

 

TIA

Ignore this, I was talking to Anglian Water and we use Essex & Suffolk 😚
