Unfortunately for various reasons the wiring has gone slightly awry in
that at a late stage I need to add a new 3C&E (mains) cable to provide
for a room stat, and this really needs to be run in the same gap - which
is now full of pipes! How close can the cable be regs-wise to the
pipes (presuambly it doesn't matter which, as in gas/water/CH?).
25mm for gas, I don't know of a reg for water.

You must allow for the heat from the heating pipes to affect the rating of
the cable. So if you can avoid the hottest pipe(s) you would do well.





I have 2 ring circuit cables running within the 150mm channel below the
ceiling. Is it acceptable to run the cables behind dry
lining/plasterboard and have the pipes mounted on top of the
plasterboard? Would the cables need further protection? The cables
would be running at 90degrees (as in angle, not temperature ) to the
pipes only for the width of the pipes (~100mm)
