Not sure if there has been a leak but no evidence. There is no insulation on any of the pipe work; could this be the problem?
Reason I am checking under floor is because I have had signs of damp but on internal wall and came across this.

Gille, good evening.
The green appearance on this pipe, "verdigris" is a direct result of moist air over a period of time allowing the formation of the green appearance.
If you think about old roof domes on historic properties that appear green is a result of rain and moist air combining to cause a reaction in the copper, hence the green colour appears.
Under your floor, the air is slightly, or greatly damper than the air inside the room above, result is that the Copper pipe will turn green, but, this process will have occurred over a long period of time, it would appear that the pipe you are concerned about is an older 15.mm or 20.mm flow or return to the Rad.
If you had a leak, then there would be a very pronounced "thicker" more intense green mark or line down the lower section of the pipe.
As an aside? if you have reasonably easy access under the floor, you may wish to consider that you insulate the Central heating pipes, even go some way further fit insulation to the underside of the flooring? Just a thought.
