The one on the basin look like they need a demounting tool. What Brand is it please. And the supply is these fittings which looks like it's demountable but what brand is it please?

Top ones are original Hep2o and are not demountable the others I don't know but someone will

1st original hep2o non demountable. Tap con will undo
2nd polyfit , demountable.

 

[ShaunCorbs]

as above and the top i think is heated up and melted and pushed together

 

[stani]

Sorry Shaun it's just pushfit

The top one looks like the old Hepworth push fit slimmer stuff that isn't demountable.
The brass nut which is part of the tap fitting definitely looks same as Hepworth. Don't remember ever seeing the "HL" on the fittings though.
A junior hacksaw carefully used through the gripper will cut the fitting off
