Part of the problem is getting the right advice, the right people to do a job and the cost. Lots of UK houses are built <1930 and have suspended floors. I was told in various quotes for floor insulation because of tongue and groove floorboards, they'd get damaged when lifted and would have to be replaced. I managed to keep them having insulated the floor with 300mm rockwool just this past month. Not only is there the benefit of heat retention, but hopefully it will kill a lot of draught entering the house also. The wholesale gas price spike meant this would have paid for itself in around 5 years (I have a combi boiler), but will perhaps be closer to 10 now. Cost all in: £400 for insulation, £1000 labour, £800 flooring replacement £200 various. If I'd went through an accredited installer I could've received a Home Energy Scotland grant of £1500. I'd still need to insulate my (600mm whinstone solid) walls for an air pump to be economical.
