Preferably not too far from Farnham please

Not sure if it helps, but the boot floor panel is double sided. Carpet on one side and a hard, cleanable, surface on the reverse.
That is all I use to protect the floor on mine, although I do use a cheap 'waterproof dog sheet' to protect the backs of my seats when they are down flat, when on my 'Council Dump' runs.

PS Oops - Just reread your short request - did you mean the extendable blind that covers the boot? FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)
FL2 Metropolis SD4 Auto 2014 2017- (16k - 77k+ miles) (MY2015)
Metro in its 11th Year of (Extended) LR Warranty / Full LR Service History
(Expensive, but Trouble/Worry free - hopefully?)

Thanks for the reply.

Yes I’m looking for the extendable blind.
