There was a similar thread not too long ago where I suggested squirrel bafflers - things like this as well as common sense really e.g. placing your bird feeder at least 6ft away from branches etc really helps too.
with regards to the legality of humanely disposing of pests I've done a bit of research. I knew a chap who would shoot squirrels off birds feeders with an air riffle (lived in the middle of nowhere) - he always said that grey squirrels were classed as a pests. SO I did some research...have a read of this article I've pasted below the main stuff from page 6. Basically you can capture squirrels but it is illegal to release them unless you have a license so really the only option is to kill them.
(ii) Section 14 of the Wildlife and Countryside Act 1981 (WCA) (available at http://www.opsi.gov.uk/legislation/about_legislation.htm) prohibits the release into the wild any animal which is 1) of a kind that is not ordinarily resident in and is not a regular visitor to GB in a wild state or 2) is included in Part 1 of Schedule 9. Currently (June 2008), the black rat (Rattus rattus), the fat/edible dormouse (Glis glis), the grey squirrel (Sciureus carolinensis) and the Mongolian gerbil (Meriones unguiculatus) are listed on Part 1 of Schedule 9 and therefore cannot be released, except under licence.
hope this helps
