Do I need pressure valves

[Bellfield]

I'm just a DIY person who has seen references to pressure regulation. I'm about to change my kitchen sink and wondered if I need to do anything about pressure. My supply is cold - straight of the main, hot via combi boiler. the present sink has nothing, (not even isolators which I shall fit, but it was installed about 35 years ago.

thanks for any advice.

No if your happy with the pressure atm and don't think it's too much just fit good quality full bore isolating valves
