Thanks PeterW - Well, ( and sorry this is where it gets interesting) the cottage is actually in a field about 1/4 mile from the main (single track) road. I think the water supply was added in the early 70s. It’s not metered and the pipe supplying the cottage looks like hard plastic (bright blue). I checked along the road for a supply cut off but couldn’t find anything. There is a value on the outside/other side of that wall in the picture. I’m not sure what response I’d get from the water company but I might give them a phone.
