Has anyone insulated under their original floorboards?

[MinimalistMommi]

We've bought a victorian property with all the original suspended timber floorboards intact, we would like to rip up the carpet and strip and wax the floorboards.

I realise they will not feel particularly warm underfoot and will be breezy, has anyone insulated them underneath?

I've read that timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists.

Is this expensive to get done?

Is this the best thing to do?

Or should we have the floorboar taken up and then repositioned closer together so they are not so 'gappy', using reclaimed boards to make up an shortfall?

We've just had extra airbricks added front and back so I think the ventilation should be OK underneath the floorboards to prevent rotting.

I know in terms of warmth we would be better of with thick carpet and underlay but I basically want the pretty look of floorboards throughout the house with cosy rugs on top.

I'm aware floorboards will make the house 'noisier' too.

Any advice?

We insulated under our floorboards at our last house (coming up from the cellar) and it was ok, but still pretty drafty. We have recently moved and this time we had the gaps filled whilst they were being sanded back and there is no breeze or drafts at all. I'd say this is by far the best option.

We did this and used that insulation stuff that comes in rolls in silver packaging (sorry don't know technical term). OH fide it himself but he was able to get under the floor. Its made a massive difference

Prince we are planning of doing the sanding/waxing ourselves, not feeling so confident on the filling myself, I wonder if there is someone I can get in to do that particular job or not? Any clues?
