Hi, Yes the planks are laid over the original floorboards. They are not loose. they have been nailed down to within an inch of their life but they are not flat. There are bits that catch when I move furniture around and there are some gaps. I know they are 20mm thick... or just under because we got one up and measured it. I was surprised at the depth of them.Not sure if the pic is useful or not.

Thank you SimonD that is really helpful. I will research the products you mentioned. I have no idea what sort of wood these boards are but I will also search and see what they are likely to be.

Hi, We bought a house that has a wonky wooden floor in the living room. It is quite thick planks over floorboards and I have thought about taking it up but that would leave a gap around the skirting and fireplaces... so I'm told. These planks are nearly 20mm thick but they seem to be quite soft wood and the varnish that is on them scratches off easily. I am open to having them sanded, filled and re stained or varnished. Does anyone have any advice as it is quite a big area and I would rather have it done properly or have someone tell me that it's not a good idea before I start getting people out. I am open to doing it myself but I am also open to paying for it to be done. Many thanks in advance.
