Monobloc Mixer Tap Cartridge

[styleprop]

Hi all

Sorry if this is a daft question, but is there any chance someone could help us to identify the cartridge in the pictures attached, or point us in the right direction?

I'm not well enough to replace the whole tap but can replace the cartridge, and unfortunately I can't afford £60 + labour for a new tap.

Any help would be appreciated.
Thanks.
