No hot water or cold water at all and my bathroom tapes no water at all or in my shower attached men

If there is no hot or cold water at the taps and no heating in multiple rooms, this points to a system-wide issue rather than a problem with individual fixtures. Possible causes include an isolated or closed supply, a fault with the boiler, a failed pump, or issues with the heating and hot water controls. The first step is to check whether water is available elsewhere in the property and whether the boiler is powered, pressurised and showing any fault codes. Given that both water supply and heating are affected, this would normally require inspection by a qualified heating engineer or plumber to diagnose safely.
