25 mm tails behind gas pipe.

[wing nut]

I need to upgrade tails to 25 mm but I have to negotiate a gas pipe. The pipe is 25 mm off the wall and is a plastic pipe inside an old metal pipe. The tails need to go over or under the pipe. ( current 16mm tails do just that )
What I would like to know is, do I need to give mechanical protection to the tails as it is so close to the gas supply or is the double insulation of the tails enough.

You will have to re route them - segregation of services, im no where near the office at the moment to give you the reg number, the only other way around it that i can think of is tray with a double set in to bridge it, but this depends on the application because in most domestic situations this will look pony!
