I have now decided to zone; 2 zones, 1 upstairs and one down. Many

Been looking at my tight layout. I have NO idea where I'm going to
put the valves.

No, there's no airing cupboard.
The walls in and around the boiler are tight with 'stuff'.
The bedrooms are full of fitted units.

Anyone everput then in the ceiling void with a small trapdoor for
access? It's about all thats left.
