Pressure will rise if boiler heating is on 2.5 seems ok, but if boiler not in use 2.5 when cold is too much, should be max 1.5, vent a radiator to reduce pressure if neccessary.

Good way to check pressure is when boiler is cold, should read between
1 bar and 1.5, if it is higher bleed a radiator to reduce pressure.
But there is also a pressure releif valve that will release water pressure from the boiler if the pressure rises to higher than 3 bar.
This water will be discharged outside a discharge pipe outside your property so no need to worry.
