Impact of low pressure on heating bill?

My boiler has low pressure (probably a leak in the system as whenever I try and get the pressure up to between 1 and 2, it goes back down a day or two later). I don't mind because the radiators downstairs are nice and hot, but the radiators upstairs struggle to get particularly hot, especially higher up on the radiator itself. My other two questions are: 1) Would my energy bills cost the same compared to if my pressure was normal and the upstairs radiators were working properly? I have no idea how it works, but my reasoning is that my energy bills should, in theory, be cheaper because the upstairs radiators aren't producing as much heat. 2) Will water be leaking somewhere even when the pressure is on zero?
