Right now we have an uninsulated basement with a Platon mat on the outside for drainage. We would like to add insulation to the basement from the outside and are faced with the choice of insulating just below ground level or the entire wall all the way down.
The company we got a quote from doesn't think it's worth the money to go all the way down, but I would still like to get tips, suggestions, and pros/cons of doing either. Can anyone provide some information on what the differences mean for me?

When sizing heating systems, it is commonly said that a basement requires about half as much output as a floor above ground. What I want to convey with this is that, energy-wise, you won't recoup the cost of the measure below ground. The Platon mat is already installed, and measures have been taken to reduce moisture. Is it otherwise a livable environment in the basement?
I think you can install insulation, like Isodrän, above ground now, and the day you eventually need to re-drain, you can possibly continue below ground. Laying it below ground costs you approximately 1500-2000 SEK per linear meter.

The latest measurement showed "normal" values for humidity.
The company we got the quote from wants 82,000 SEK after the ROT deduction to insulate above ground (7cm thick, and they go down about 1 decimeter below ground), apply plaster, and replace 6x 6x10 windows.
For now, we are satisfied with starting like that and then going all the way down the day we re-drain. Whenever that will be. Right now, I believe the carpet is about 6-10 years old.
