Could be numerous faults. Most common is either blockage or airlock in the pipelines

Filters been checked on the showers?

If the mixer is over 3 years old it may need replaced, especially if it's a budget one

Possible low pressure or limescale build up in shower head.

There could a number of faults. Most common is either blockage or airlock in the pipelines.

Either pipework is crossed to shower unit or thermostat is faulty or preassure issue...

maby there is a valve off or its a plumbing mistake

Mixer in shower fulty

could be piped wrong, are there any isolation valves shut off going to showers, are the showers new and or suitable for a combi

Possibly isolation values shut off on hot water feed to showers

First floor showers will need to have a pump if hot water flow rate is low.
Gravity is the cause

Get a plumber to look into it, probably the pump is gone.

Main reasons;

1) Not connected to water system
2) Have they got isolators and if so are they open
3) Shower Valves Faulty
4) Shower Filters Blocked
5) Insufficient water pressure
