Either depleted expansion vessel on heating (red) or hot water (white, potable)
Faulty pressure reducing valve, if the hot water is scalding could be faulty thermostat. Or over pressurised heating circuit.

You will have a pressure relief valve that is letting by. Easy to get changed, it also should not cost much

Sounds like faulty expansion vessel, replace. The red one for heating.
