Uni of Liverpool is RG and their offer is ABB.
UEA is AAB and some others that are 'AAA - AAB' include Kent and Surrey, both pretty good. Not sure under which circumstances they give the AAB offer instead of AAA, though. Southampton offer is AAA but if you get an offer and miss it they tend to let in a lot of people with AAB and ABB. I even saw someone with ABC.
I also think you're very sensible to apply next year, with ADDE you would have a tough job getting offers so once you've hopefully got AAB under your belt it will be much easier for you. You could always even then retake a module or two in your gap year for higher grades.
