I've recently had a new bathroom put in, with a mains shower (used to be electric). But now my shower keeps running hot-cold-hot-cold every minute or so. My bath tap and sink tap in the bathroom are running fine, it's just the shower.
I was told this shouldn't happen as I have a combi-boiler but without fail, every shower I take is the same!
Can anybody tell me why this is? Do I need to get my boiler checked? Is there anything I can do?
Thanks!

When you say "combi-boiler" do you mean a CombiCor by Bradford White?

No, it's a Sarigas Combination Boiler. Any help?

Could be the hot and cold water controls of the shower. What is the brand and single handle or 2?

Sounds like a problem with the pressure balancing in your shower. Not a boiler problem.
