Product name request

[Captain Goovibes]

I have a slow leak in the bath. Its a mixer type set up. I'm unfamiliar with the tap handles and how to access the cartridges etc. If I can work out the product name/brand/type then I can work out how to remove the tap handles (no obvious indices so presuming they pull off some how). Would anyone be familar with this type of tap shown in the photos. Any asisitance is greatly appreciated.

Thanks

Not familiar with it but it looks as if the small circular section in the centre of each “hot cross bun” should just prise off and there will be a screw underneath which holds the handle on.
Same with the circle in the centre of the backplate should you need access behind it.
