OP I think you've got the wrong end of the stick here and I don't forsee you actually getting any, or maybe a small amount, of UC once you transition.
Capital is disregarded over 16k for the first 12 months, that's your transitional protection, yes. But all that means is that you are still allowed to claim as under normal circumstances you aren't entitled to claim UC at all with savings over 16k.
Even in the first 12 months your award will be reduced for any savings between 6-16k. This is called tariff income, so I'd be very surprised if you received anything. The protection whereby you are awarded the same on UC as on tax credits is misunderstood, it means if your tax credit award is 1,000 per month then your UC award won't be less than that, however the reduction due to savings comes AFTER the award amount so it could still be reduced to nil.
The relevant info from revenuebenefits is this:
"The transitional capital disregard for tax credit claimants. This means that tax credit claimants who migrate over to universal credit under the formal managed migration exercise will have any capital over £16,000 disregarded for up to 12 months from their date of universal credit claim. Capital between £6000 and £16000 will still attract tariff income."
And tariff income is explained here from Shelter:
"Capital between £6,000 and £16,000 is subject to a 'tariff income'. This means that the claimant's universal credit award will be reduced."
