The surround normally prises off to expose screws that secure switches etc to wall

Many thanks for that. It's what I suspected but didn't have the courage to exert the force needed, it's now off without damage. I suspect though that there is a special tool to slide into the slots visable in pic 2 on inspection. Thanks again.

This is what's under the cover.
