10mm plastic pipe (SW14, East Sheen)

Hello, I need a short length - less than 50cm - of 10mm OD plastic pipe. I would really appreciate some if you have a bit spare or even the end of a roll gathering dust somewhere. I don't mind Hep2O, Polypipe or other brands as long as it is 10mm OD. I can bring proper cutters to snip a short length off a roll if preferred. Thanks in advance....
