Not an ideal solution, however could be up for consideration http://www.ukelectricalsupplie...-lighting-au-fgdb.htm

Aren't they just metalclad switches mounted on a lump of wood Rocky, no different to mounting a metalclad socket on a lump of wood and nothing to do with the OP, doesn't really prove anything does it,

And that's why I pointed out to Andy that all the wooden sockets I have seen have a metal plate to protect the wood, so they aren't really applicable to the discussion on here either. Lets not compare apples to oranges

And for the record, I would probably go with the fire retardant stuff and note it down as a departure/deviation or whatever else you choose to call it.

But that's just my opinion and should be taken as so.

If you really have to keep the wooden boxes: how about using these and no departure recorded.
Intumescent box liner

I would still prefer to replace the boxes if rewiring; unless being a listed building restricted the work.

Have a look here: http://www.youtube.com/watch?v=T5tjyJAbTZg - there looks to be a fair bit of exposed timber around the edges of the inside to me.
