It matters not one iota what the unit rate and standing charge are. The only figure that matters is the total annual cost. Put your 11,000kWh and postcode into any accredited comp site and it will tell you the cheapest tariff.
The point I was trying to establish is whether your claim that this was 'heavy consumption' is correct or not, and without knowing the basic size of the property and heating system, that cannot be determined.

It's fairly basic accounting. This is not the best explanation but it might help.

Basically if you're a heavy user you want high fixed costs and low unit costs and the opposite if you are a low user. So it does matter.

I understand what you're trying to say about property size and heating system, which isn't electric, but If the average UK property uses around 4,000 kWh a year, 11,000 kWh is heavy consumption.

You are entirely missing the point. I'm well aware that you want a higher s/c and lower u/c for higher use, but each and every comp site works this out for you once you've put in your kWh usage and postcode. No need to worry about analysing individual tariffs: a comp site will do it all for you in about 30 seconds.
Since you've now confirmed that the consumption of 11,000kWh is excluding heating and DHW, then yes, they are extremely heavy users, so much so that something is awry and needs investigating, rather than just looking for a cheaper deal.
