@Acliff went for this extractor. Indeed they were helpful on the phone and that I wouldn't notice much difference vs the more expensive one you linked if I am recirculating.
Only recirculating as I cba on the builders behalf for the faff/cost of venting out of 2 ft thick 19th century wall. Catching up with the builder tomorrow so might see what he reckons..
