Firstly, just to say, to acknowledge the point, Chair, I do think it's a wide range, obviously, a variance of 30 per cent either way. The challenge for us is to strike the balance, if you like, between—. I was mindful, really, of the predecessor committee's focus in relation to the implementation of the Higher Education (Wales) Act 2015 legislation, which was, essentially, critical of the Government for underestimating the resource needed to implement that legislation. So, I didn't want to be in that position, if I can put it bluntly to you.
So, the figures, generally speaking, are the best estimates currently available. We obviously have the cost base for HEFCW, the cost base for the Welsh Government, the cost base from the experience of establishing other comparator organisations—so, for example, Qualifications Wales. All of that has fed into the cost assumptions in the document, but there are obviously operational choices which will significantly affect those options. So, you know, as you would expect, they're about location, they're about IT, they're about staffing, principally.
What I would say is that 30 per cent variance will not apply equally to all elements of the costings. So, many of those costs are at the very high end anyway, so that we can be prudent in what we're telling you. I think it is very, very unlikely that you're going to see a 30 per cent increase even in the absolute worst-case scenario across each individual item. There will definitely be examples, it seems to me, of where there'll be decreases in some of those estimates.
So, if you look at the effect of COVID, for example, what we know from that is, broadly speaking, IT costs have probably increased as a consequence of pressures on equipment and on consultancy, but location costs, probably, you'd expect to come down because of changes in the pattern of working, remote working and so on. So, I think all of that is quite new because we're living with it at the moment. So, we'll need to work all of those through.
Just to say to you, there'll be—the cost implications are reviewed on a monthly basis and, I think, very importantly, if I may say, I've established a strategy and implementation group with stakeholders from right across the sector and they will help us work through some of these kinds of more granular choices as we go forward.
