Kitchen tap mixter sudden stopped working

Cold water side works but hot suddenly stopped working.
I’ve checked that there are no leaking pipes. Any idea? I got it installed 1 month ago. Is it down to a poor installation???

Picture of tap and pipework supplying it would be useful.

Update: the hot water issue seems to happen every week either afternoon Friday or Saturday? Sometimes it stops for a few hrs to half a day. It’s really puzzling me

do you have a presure drop at them times, as the taps look like they are the lift type,and that one may be sticking.

Thanks for responding. The pressure you are referring to is the boiler right? I’ve checked the screen. It doesn’t drop, or it’s not noticeable. Would you increase the pressure to test? Atm it’s at 1.5

no!!!!! its not the presure in the boiler , i mean your incomeing water presure to your cold tap, as if this drops at them times then your hot water presure will allso drop. at your tap and if the hot tap is sticking then it will poss not work.
