We pay a lot of attention to making sure we aren't duplicating that spending and trying to make sure the investments made by the regulator versus the investments made by the department are aligned, complement one another and indeed aren't duplicating each other.
We actually do those reviews as proposals come forward and as the increases come forward. Those are the challenges we get from the centre, from the Department of Finance, on which they want that assurance, and I think we can say quite clearly, sir, that the increases aren't duplicating the kinds of investments we've been making with respect to energy data and energy information.
