I was not saying it could not be done, but
concentrating 12 % peroxide which more
realistically would be 10% by the time you get it
done means it's going to take a lot of base stock
to get any reasonable final quantity.

Just thinking out loud here:  if one started with 12% and ran it through an electrophoric column to get an "electrophoretically pure" start solution, then processed in the usual manner up to 85-90%, followed by freezing of remaining water up to the desired concentration, would one not then end up with a nearly pure mix of peroxide and water?

It's very unlikely you would ever get a great deal of peroxide from it as when water is added the PH of the solution becomes alkaline which allows the peroxide to disassociate very quickly on most any organic material. The possible way around this would be to add it to a acidic based water to get the PH below 6. However you still have major contaminates to reduce out before you would even attempt to concentrate this. Being restricted to12% aqueous H2O2 In the UK is going to make it tough for you to get any reasonable amount of rocket grade peroxide

Greetings,
Sodium Carbonate Peroxide is sold in the UK (and most likely in other teritories too) as "Vanish" laundry detergent. It can also be had at low cost from chemical suppliers.
Apparently it is about 27-30% H2O2. Does anyone know the alchemy required to extract the H2O2? I have read various conflicting accounts of how to do it.
