Nikon do not do it them self but have a few service shops they endorse in the UK.
Nikon U.K......Only the best!
TBH the only advantage to going direct to Nikon UK as opposed to a Nikon authorised repair centre is that Nikon UK are more likely to have the parts on-hand...and even that's not always the case - had to wait 2 months for the repair to my old D1x - a new little rubber-cover to the Firewire/video output jack on the back... £90...hmmmm
