Fixation

I'd guess it's probably the repair facility most widely used by news and editorial photographers in London, with a wide range of expertise in both Canon and Nikon. They're also the UK Service Centre for Quantum flash products. Extremely knowledgable and courteous people at their office and a fast turnaround for repairs, digital camera sensor cleaning and modifications. Also a good range of second hand digital camera equipment and sometimes hard to find new bits and pieces for your gear like sensor brushes and StoFen flash covers.
