Jsa has this exactly right. It depends on how the power you are charged for is actually measured.
Power factor correction may or may not lower your electricity bills, but it should in theory reduce the supply current, if only slightly. The problem is how much correction? Overcorrection is actually worse than no correction.
You really need a power factor meter to do this, and they are not a very common measurement instrument. Funnily enough I actually have a power factor meter here, but I have never actually used it.
