Shower losing temperature

Hello. Think we need a new cartridge but just looking to verify. Shower starts losing heat almost immediately, although temperature will increase briefly when you turn up the temperature or the pressure on the shower dial. Have checked filters and they look clear. Many thanks.

Oh, and should say that the shower temperature eventually 'plateaus' at a warmish temperature. Doesn't seem to be a general issue with the hot water as it is possible to run a bath immediately after that is very hot.

Many thanks,

Andrew
