Andy - if you are prepared to mail your film, try Palm Lab in Birmingham -
www.palmlabs.co.uk they have all the traditional services including hand colour and B&W printing, and offer a great personal service. I wont use anyone else.
They also have the latest digital services too of course, such as Imacon scanning, Chromira prints up to 50" etc. and they recently installed a new 50" paper processor.
Steve, who owns the company, has been printing colour since he was 13, and his right hand man, Simon, also has similar experience. They have Kodak Q-Lab acreditation and all prints are onto Kodak Endura. They also keep Endura Metallic in stock. Film processing is in "dip & dunk" machines, not RT, and this offers the most reliable and cleanest results.
