Thanks for that. So, as you mentioned, we have a programme, Adfywio, which looks at reducing, some decarbonising, in relation to our built estate and our fleet. So, we are making progress. We have a dynamic accommodation plan, that's dynamic in the sense that we have a broad sense of what we want to do, but we're going to be flexible in terms of opportunities that might arise over the next 70 years. So, we have a very large estate, built estate. We know that we need to rationalise and derive savings, both carbon as well as money, from that.
When I say dynamic, that means often co-locating, working with other partners. So, for instance, we've identified an opportunity in—[Inaudible.]—to co-locate with Powys County Council, which avoids us having to look for our own accommodation for our staff in that area. So, that is one element where we're taking opportunity.
We have a number of other opportunities on the horizon where we have lease breaks or changes in the contracts that we have in terms of accommodation. One in particular is around Tŷ Cambria, which is our corporate policy office here in Cardiff. We will be leaving that office, ending the lease, in mid 2024, and we'll be moving into Welsh Government offices here in the centre of Cardiff and taking some of the spare space in Cathays Park. That will save us over, I think, a period of 10 years, between £3 million and £4 million, so a significant financial saving, but also halve our emissions in terms of heating and electricity.
So, those are really good opportunities that we're looking to do. We're also looking at efficiencies in terms of fleet as well, putting policies in place that prevent us, really, from procuring, say, diesel or fossil-fuel based vehicles unless there's an—[Inaudible.] We might have exceptional cases because of the nature of the work that we do and what the market currently provides, but really we are shifting very quickly in the direction of transforming our fleet as well.
You mentioned staff as part of this. We have undertaken surveys of staff in terms of what they want to have as a working pattern going forward, and the really clear message was that staff valued the flexibility that we offer and we continue to offer that in terms of working arrangements, but that teams need to decide how best that will look in terms of the nature of the work. So, operational teams, they will be out working, they will need to be working in the open air or meeting in—[Inaudible.]—and so forth. Maybe, for other more office-based staff, we are providing flexibility, but we are clear that managers also need to have the ability to bring teams in to work face-to-face at particular points, and that they need to develop those arrangements and understanding themselves, taking a mature, trusting approach, but that we also need to provide appropriate accommodation for staff to come and work effectively, and have those really productive face-to-face meetings that you sometimes need. Sometimes the face-to-face model like today works in a transactional sense and it works really well, but sometimes you do need to meet up, effectively, and have somewhere that you can have that face-to-face contact for good work reasons, but also for well-being and personal reasons.
