Well I made enquiries and the answer is....a shredding party!
I found a firm who can do it for 35p per kilo, but their minimum charge is £60, so they suggested seeing if friends, relatives and neighbours are interested in bringing their shredding along and to share the cost. They do it front of you on their van so you know it's done.
So if anyone is interested let me know!
Ps, if there are any more sexist comments it may be more than paper that gets shredded!
