What 1997 tells you about the pipe in Ashton
Housing of this vintage generally means copper as standard and the last of the polybutylene, which stopped being installed in 1995. Pressure complaints in houses this age are more often about the pressure-reducing valve drifting out of adjustment than about the pipe. More on 1990s supply pipe.

In Ashton the first check is how many taps are affected, and on housing of this age a single weak one is the common case — an aerator or a supply stop, not the system. Normal supply is 45–80 psi; under 40 psi is low, and a gauge tells you in a minute. Whole house is a call; one tap is not.
