Hello Silk789,
Try DGS Military Hobby at dgsselkirk.wixsite.com They offer a 1/16 Sherman Firefly resin conversion kit (upper hull, turret, hatches, barrel, etc.). It requires a HL M4A3 Sherman lower hull. I have this and it is good. The upper hull is for a M4A4 Sherman, but it fits, looks good, no need to lengthen the lower hull. I hope this helps. Plus they have some 1/16 accessories. Also I believe they have a distributer in the UK.
P.S. They also provide water slide decals of good quality.
