Another niggle now the bathroom is all high pressure. Occasionally for no apparant reason the toilet cistern will fill (after already being full) for a second or so. It is a new toilet (French) with the internal overflow and dual button operation. I've swapped over the seal to change from low to high pressure supply. Any ideas?

Is it an equilibrium valve?
If so what might be happening is that the float is initially closing off the small escape of water from the front part of the valve to a sufficient degree to close the main valve, but then it continues to allow water out and the valve briefly opens again. The float rises a little more and now really does close off.
This can be made worse by high pressure, but you say you've dealt with that. I would examine the behaviour of the valve closely and in particular look at the area on the front of the valve where the pad of the float arm closes the pin hole. I suspect you will see water escaping after the first close of the main valve.
This may be due to a piece of crud in the pin hole or a manufacturing defect in the valve. If it's not obvious, I would ask for a new valve.
French and bathroom do not mix, seriously.

No idea, what's one of those?
There was crud, I've removed it, I'll see how it fairs. Thanks Andy.

anyone who remembers The Secret Life of Machines - the whole lot are there to download. Splendid, they are.
for example, a Torbeck or Fluidmaster although there are many more
You can Google for these brand names. Designs vary, but the principle is of a diaphragm in the body of the valve and a small hole for water to escape.
It's really important with these to flush pipework thoroughly when doing new plumbing.
