First check that the head and hose are clear then if they are check the filters on the thermostatic cartridge. It maybe the boiler if it is a combi.

To check whether you have a boiler or shower fault.

Turn the shower on as usual, try and get a hold of the pipe going tothe shower, if you can’t get to the pipe at the shower you may be able to get toit as it leaves the boiler.

What ever the temperature is on/in this pipe, the shower can neverget any hotter than that (So if the temperature is cool then something then atthe boiler is not allowing the water to heat up enough)

The other fault is wide variations in thetemperature of the water leaving the boiler.

A thermostatic shower valve should be able to even out smallvariations in temperature however if you have large variations then you have aboiler fault.
