Electrical Sockets on Wood

I need to rewire some old wooden stables. Is it acceptable practice to mount sockets and lights directly onto wood (ie combustible surfaces)? If not, what material should I use to mount them on?
Many thanks.

All modern surface-mount fixtures, whether plastic or metalclad, themselves form the required non-combistible enclosure; so mounting on wood is OK. For a use of an old stable as workshop/living space, that's about it: if workshop in non-managment-consultant sense, metalclad fittings and cables/singles run in plastic conduit probably makes more sense than surface-run ordinary PVC T&E (unless you can arrange the T&E to run in places it's unlikely to get knocked).
If there's livestock involved, you need to pay extra attention to reducing touch voltages in the event of fault - in practice this means supplementary bonding, shorter runs of "normal" cable or extra CPCs running in parallel, RCDs, and the like: combination of hosses allegedly being more sensitive to shock, not wearing socks + plastic-soled shoes, and standing on floors with a relatively low earth resistance all conspire to make this (a) sensible and (b) Required.

More than that, you DO need to measure the voltage gradient around earth spikes, when there is a fault, more than 25V can cause problems, it is a long way between front and back hoofs on a bull!
