Hi

Not sure if this is the best group but does anyone know a UK dealer
for the above - they are at www.roperatchet.com?

A Petzl Ascender would do the job, eg eBay 120133093026. There's a few used
ones listed on ebay, you'd probably get one for a tenner. They're built to
hang people off, and very widely trusted to do that, so you know the
quality's there.
