If the fuse keeps blowing you must have introduced a dead short by incorrect wiring

is the photo above on the right taken before you took the old one off the wall ?
 
Short circuit? Any photos of wiring new stats up?
Unfortunately I didn’t get none when wired in 🙁
first two photos are Honeywell
Last four photos are drayton
I hope this helps

I can fit any sort of stat there like a Digital one ?
Depends on the type, as Shaun said. You can get 2 wire ones which just use live and switched and run off batteries. If you want a smart thermostat such as Nest/Hive, then you need permanent live and permanent neutral supplies.
