Parents have a traditional style house with consumer box under the stairs that is central to the house with rooms all around, however solid floors ground floor. They want a charging point outside, and I understand the new cable has to go from the board to outside wall for the charger unit?

I am thinking cable needs routing upwards, then under the floorboards, to outside wall then go from there rather than knackering wooden floors or duct.

Is there any alternative, or downside to that, or is that what others have done?

I am guessing a case of get electrical in to do all that then installer in to do the outside bit?

Basic Qs I know - but guess there is a fair bit of experience on here smile

Depends.
I am going to assume for the moment that you don't have a meter box on the outside of the premises.
If that is the case, then yes, your idea is good.

If you do have a meter box, then use an external consumer unit and connect via Henley blocks in the meter box.

The installer will typically also route power back from the box. The installers are sparkies.

Just get a local chap in for a quote, it's free.

Many will simply split the feed from within the metre box and install the relevant switchgear in the metre box if that's significantly more practical than taking a feed from the house consumer unit.

That's technically a grey area as the supplier 'owns' the meter box and the space within it, but it's not dangerous or against regs. Probably half of the installations I have seen are done that way.

Get a local in and they'll explain what's best and why.

Yep. My meter is in one garage but the consumer unit in an adjacent garage. They simply took a radial feed from meter point breaker and put a new cable and isolator to feed the charger unit.
