As for the OP, as per everyone else, dont pay till your happy.
I am sure Tiff will explain but basically you need to close all the valves and then crack the ones further away from the boiler open fully and the rest less to ensure the heat gets to the furtherest radiator.
On my house for example as its upstairs I need to close the upstairs valves and the crack them a little so the majority of the heat goes down stairs where I want it.
Its loads more technical than that but its a good starting point.
