Ground floor flooring what am I missing?

[TiddleTaddleTat]

Ok I have trawled previous threads but not found the answer I need.
we have temporary flooring on all of the downstairs of our 1930s semi. slowly renovated over 4 years and have left flooring to last.
current plan is tiles in the kitchen and conservatory (potentially with UFH though would need to be electric I think - both concrete floors).
want a hard floor in the open plan living / dining room which currently has the unfinished / badly finished and draughty floorboards.

dont want LVT , laminate or bamboo due to formaldehyde off gassing / eco impact.
engineered wood is looking like a possibility.
is it worth insulating under the floor or putting in UFH in those rooms if they already have central heating?

for the tiled rooms mentioned above neither currently have any heating.

budget is £5000 for the whole ground floor - about 50sqm. what should I be considering in order to make this most cost effective? Can do it in phases if the budget isn’t going to stretch to all at once.

thanks

That's interesting about the texture. Hadn't thought of that. I've ordered the larger sample and will stress test.

We recently fit cork flooring to our house. It clicked together really easy just like laminate flooring so if you can fit laminate you could give the fitting a go yourself to save some money.

We liked the cork flooring that looked like cork but it didn't really fit our style of house so we went for a range that looked like wood. It's like a cross between cork and laminate but because it's made from layers of cork it has a softer and warmer feel than laminates or LVT and is more eco-friendly and sustainable.

We picked this range from a website called Flooring by Nature and are really pleased with it:
