Our Bristan mixer shower is not hot enough. I have taken off the tap and turned the screw fully to the hot side but still it is only warm whereas the wash basin is very hot. I read somewhere that it may be the cold water pressure is too strong and that I may have to get a pressure reduction valve fitted. Is there no insert you can put in the shower hub to reduce the cold water flow? Help please.

Is the shower mains cold fed and gravity hot? If so then unfortunately this not been installed correctly as they require reasonably balanced supply pressures to work effectively. I.e. mains cold and hot from a combi or from a hot cylinder and cold storage tank.
Do the feed pipes to the shower have isolators? Turn the cold one off a tad and this may allow it to work correctly by lowering the cold flow rate though not ideal and not guaranteed to work as it does not reduce the pressure, which is probably your main problem.
Fitting a pressure reducing valve on the cold would be the alternative as you mention but you need to know the hot pressure to purchase the correct valve and balance correctly.
Ideally though a cold feed to the shower from the cold storage tank to balance with the hot cylinder feed would be the ideal fix.
Not sure if bristan have inline flow reducers for your shower but again this will not sort out the unbalanced pressures.
