So can probably go to 10A - my logic being:

10A type D should offer around 200A peak for a couple of cycles during switch on
During normal use I'm expecting a couple of amps, so will be OK there
If there is a problem on the primary the 10A MCB should go first as the coil can take 15A and the wall fuse is 13A
Chalon sell the double pole 10A type D for £10.25 all in . . !
Worth a try?
Exactly What I was going to suggest. I think you'll find that you can even get away with 10A Type C. It's worked for me many times before just to get going so try this if you have one.!
