Can anyone recommend a good collection center, veterinary or otherwise in the UK?  I have heard various reports about a couple, some good some bad and wondered if anyone here has experiences (good and bad). 

There's the woman who scans in Derby, she also does Ai including for export.

Keith Shea at Preston....

The woman at Derby only does fresh semen insemination and I believe doesn't have the facilities for frozen or chilled semen.

She can send for Export.

She's have to freeze or chill it for export. Without those facilities for that it must have limited use; fresh semen's no good for KC registration because it means the dog is still alive and resident in the UK!

Ditto Keith Shea, never needed his AI expertise, but he is brilliant.

Tweed House in Leeds are excellent. http://www.tweedhousevets.co.uk/reproduction-clinic/
