If you could, that'd be very helpful. Thank you 👍

@Kacha , have you had any quotes yet for how much it'll cost to dig up the existing floor? I'd like to do the same with my house (1990's, ~65m2 ground floor area) as you're planning, but have no idea how much it'll cost.

Do you mind me asking how much your builder has quoted to dig up the existing slab and replace with UFH? Is it going to be a lengthy process? I'm considering doing the same - existing ground floor slab is ~75m2 with ~25m2 extension.

Hi, I own early 1990s detached house. It has cavity walls (75mm I think), which the previous owners had filled with polystyrene beads. The floor is uninsulated concrete. Windows are all double glazed. I'm trying to find out what measures I going to be needing retrofit to it, the get it up to the standards needed for the UK to be net zero by 2050, but not having much joy. I think the obvious ones are: Loft insulation, Replacing gas boiler with air source heat pump, Fitting solar panels on the roof. But what about: External insulation, Triple glazed windows, MHVR, Digging up the floor and insulating underneath? I've read about the Enerphit and AECB retrofit standards, but I can't see what they're based on or how they fit with net zero. In the short term I'm most interested in finding out about floor insulation. I'm wanting to replace the kitchen, so if the floor does need insulating then I'd better do that first... Can anyone point me in the right direction?
