Shower periodically going hot and cold

Hi there Checked out the cold water supply coming in to the property and the valve at the shower end and both are fully open, also checked the shower hose for kinks and the shower head for blockage etc all ok, would it now be time to change the Flow Control Valve ? Do you have a link to the part please Redring Expression 500 8.5kw

Looks like you have already read this below.

Hot cold cycling

First check that the valve coming into your house and the valve on the line to your shower are both fully open if they are OK then it is likely to be a faulty stabiliser / flow valve.

The reason for this is there may not enough water passing through the shower to keep it cool, if it overheats the safety device cuts of the power until it cools, once it is cold the safety device turns on the power again and the cycle starts over.

It may be worth phoning your water supplier and checking that they haven't had the water pressure turned down for any reason, your shower needs a minimum of 1bar to work properly.

Therefore the link to your flow valve is below.
