Just an update on this. The noise was actually being caused by the tyre. Just bought the car recently and the tyres were all a bit crap. No wheel balance issues or any sign of actual damage, however having got 4 new tyres, this noise has gone, and a braking judder at precisely (weird!) 35 mph has also gone. Must have been something amiss with them!
