How to reduce the pressure?

Our Potterton Performa 24 is not heating properly since a new gas engineer for the Landlord tetsed it. The pressure is up to the 3 + mark and goes higher when the hot tap is turned on. How can we reduce the bar pressure?

bleed water from rad air vent though the high pressure shouldn't affect boiler performance
