Help getting access to the mechanism of this tap please.

[ChrisGid]

Hi, can anyone advise regarding getting access to the working mechanism within this tap. It's leaking and I want to change the washer. There's no grub nut around the base and as can be seen there's no access via the top of the tap. I'm thinking that the top skirt will unscrew with the help of a wrench and some protection but I don't want to try that until I get some confirmation advice from you guys. Ta

Probably undo the shroud and the top will come off as one rubber gloves might help you grip it

Have you tried unscrewing one of the crossed handle spindles?
