But primarily for your hot water, your central heating.

That's about 85% of households in the UK have electricity and gas.

About 15% don't have gas for central heating and things, don't have a gas connection.

So they're different.

But basically, using that sort of household on what we call typical consumption, so that is...

You know, the typical household, not particularly big, not particularly small, that sort of household.

We calculate what that consumption is and what the cost of delivering energy to that household should be.

And as I say, add a small profit element.

But we can go through the different elements.

The biggest element, sort of as you'd expect, of that £100 part of the bill is the actual energy itself.

And that is electricity and gas.

And that accounts for about £40 out of every £100 on your energy bill.

So it's a big chunk, but it's less than half.

And that's because there's lots of other things in people's energy bills.

So it's quite a lot of investment goes into that and that's 28 pounds in every hundred.

So that's another big chunk.
