No, not expected usage. The 3.45 you're referring to (I think you mean 3.3 kw) is the maximum power you can be drawing at any one time. Draw more than your contracted maximum and the meter will trip out.
What folks are telling you is that your bill will be less if you contract for a lower maximum than you currently have.
This is true to a limited extent, but I would first want to know that I was going to save enough on my bills to warrant the reduction. 3.3 kw really is rather low when you consider that, for example, if you have the kettle and the toaster on at the same time, you could be up close to that total draw, without anything else you might have on in the way of lights, heating, oven, tv, etc, etc.
I have spoken to a lot of people who find that 3.3 just isn't enough these days, even for a holiday home. We are on 5.75 kw maximum draw, and we never trip out.
I recommend that you first ascertain exactly HOW MUCH you will save by reducing your maximum. It has NO bearing on how many units you use, or the price per unit. To help you, I have uploaded a snapshot of my bill for April, so that you can calculate what you would pay on 5.75.
