UKSAR could have been made a not for profit organisation when removing it from the military, an option that doesn't ever seem to have been considered.
That's exactly how it was being run, at huge expense to the British tax payer, by the MOD?! I don't see any way you could have removed it from the MOD, re-equipped the whole force, changed everyone's Ts&Cs, licensed the whole organisation so it could operate, save money, then ask the operator to do all that for a big thank-you after 10 years.
All that would have happened is the same bidders would have submitted the same solutions but akin to the way Defence Estate services operate. I.E. The upfront risk would have been passed on to the D of T by way of massively inflated bids. No profit here guv'nor honest!
