Filling holes in floorboards - urgent advice please

[Porthole]

Hello

Having carpet fitted shortly and there are holes in the floorboards e.g. where old radiator pipes were poking through. Can you please advise on best way to fill? Builder just foams everything but I think there will be a dip in the carpet for the larger hole. Can all purpose wood filler be used?

Thanks - any comments kindly received - carpets fitted soon so need to work out what to do asap so it all dries!

Tapered wooden peg knocked in and glued, cut them flush when dry and if you want to then a quick smear of a part wood filler into any remaining holes. Use 5 Min Polyurethane glue so you don’t need to wait for it to set overnight.
