Cheapest / best / easiest way to sort out driveway

Cheap and cheerful old road planings which if laid with care isn't too bad.

I don't think that sand is accepted as a permeable substance. See link below.

No but it is always bedded on soft sand , which is what I said !

the substrate is is something else but obviously free draining as the OP did not report any waterlogging

No it isn't always bedded on sand.
Glass aggregate is used by some installers.
Also ,I have copied below an extract from the guidance contained in the Environment Agency's document

Conventional block paving is not designed to be
permeable. Its sand filled joints soon clog up to provide
a sealed-up surface and the aggregate below is not
intended to handle water. Although looking similar to
conventional block paving, permeable paving should
have permeable aggregate (looking like coarse, sharp
or crushed stone) filling the joints and under the blocks,
not sand. In addition, a recent planning appeal decision
highlights that a permeable sub-base must also be
used below to comply, not standard ‘Type 1’ aggregate,

To offer a snippet to help;

There are 2 types of "block paving" that to the untrained eye appear the same. There is the conventional block paving, typically made of coloured concrete at 50 or 80mm depth (your choice but I would have 80mm) and porous block paving such as Formpave - they were a pioneer of this.

Porous block paving is to a different detail to block paving - there are slots /gaps between the blocks on a porous block surface.

A gravel surface will be porous, as can be porous tarmac.
