Water flow is normal when on cold. As the tempterature goes up on the control the water does get hotter but the flow reduces. Any ideas?

The temperature and flow rate are always (Nearlyalways!! and always in your type of shower) connected.

When you turn your shower on you have a10kw element heating the water and this does not vary the way youalter the temperature is by varying the amount of water that passes over theelement, pass the water over the element slowly (a little water) and it getsvery hot, pass it over quickly (a high flow rate) and it doesn’t have time topick up much heat.

This explains why in the winter at thesame setting as the summer the shower is not so hot because the temperature ofthe incoming water has changed. 
  
If the floww on hot is too low then check that the inlet filter is clear that the inlet valve is  fully open and that the head and hose are clear.
