When all else fails, ask uk.d-i-y .........

The Management has asked me to repair a Tefal Express model 2911 steam
generator iron for one of her friends. The problem is that the fabric
sheath which normally encloses the mains cable and steam tube between the
base unit and the iron has lost its anchor point at the iron end and has
shrunk back, exposing the mains flex and steam tube for a distance of about
15 inches. In itself this would not be a great problem, but the user seems
to have abraded the loose mains flex, wearing through both the outer sheath
and the inner insulation on the wires exposing the copper conductors.
Clearly, this is very dangerous and the flex must be replaced.

Unfortunately, after several unproductive hours smurfing the Interweb I am
unable to find any listing for either this cable, or the complete sheathed
cable/tube assembly, on any website selling Tefal spares, and the only
0.75mm 4-core heat resisting cable rated to 90 degrees Centigrade I can find
comes with a white sheath, making me suspect that it's PVC rather than the
black synthetic rubber of the original, on a 50 metre drum at a cost of
nearly twenty pounds.

Please does anyone know where I could purchase just a few metres of said
cable? I live in Hatfield, Hertfordshire.
