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.
 
That’s fine

the box which the thermostat talks to goes where your wiring centre is then the thermostat talks to this box with just two wires or just gets power via these two wires
