Bristol, (1 resit attempt per subject)
HYMS (BBB first sitting)
UEA, (ABB/AAC first sitting and an A* in one resit)

Edge Hill, (no restrictions)
Kings (though they do say “applications from students that have achieved, or are predicted to achieve our typical entry requirements in the first sitting, may be more competitive overall than students who have not reached the grades required upon the first attempt”),
Queen’s University Belfast (Resit candidates are only considered if they previously held an offer from Queen’s at the first attempt and made it their conditional firm choice). Need A*AB/AAA at A-level or AAB at A-level plus A in a fourth AS-level at first attempt.
There is also BSMS (AAB first sitting) and Lancaster (ABB first sitting) if you do BMAT.
Edited for 2021 entry (I suspect the first of many):
Aston's new requirements for 2021 entry
"Applicants who have resat, or are resitting GCSEs, A Levels, or equivalent qualifications, with or without repeating an academic year, will be considered. The referee must provide a brief explanation of the reason (s) for the resit in the UCAS reference."
Birmingham we will consider a UCAS application without bias on the basis of future examination grades (achieved either in autumn 2020 or summer 2021; each subject must be examined in only one sitting). However, in order for us to consider your application, your current Centre-Assessed Grades must be provided and be no more than two grades below the offer that would apply to your application (i.e. ABB for standard offer; BBB for contextual; BBC for our Pathways to Birmingham applicants). The relevant offer grades must still be met. We will accept a combination of CAGs and examination grades when we evaluate the final profile and accept the higher of the two grades for each subject.
HYMS have clarified that if you are to resit your A levels you must resit all ones you are planning to resit either in Autumn or Summer, you cannot spread them out and sit some at either sitting.
Bristol and Sheffield have clarified they will accept a mix and match of exams sat at either sitting (but then both accept resits now and although Bristol say just one sitting, the Oct exams are clearly not being considered a resit)
Liverpool are saying that Autumn resits only will not be considered a resit (and presumably exempt from first sitting minimum grades). Their website says "Calculated grades (awarded in 2020) are considered to be equivalent to A-level grades and so we will consider your application based on the calculated grades declared. However applicants may choose to take A-levels. Both grades will stand and at Liverpool we would therefore use the best combined grades in decision making. Applicants from England, who choose to take A levels, will be expected to be taking their exams at the autumn sitting, should these be available.
However, please note that if you applied to us we may request clarification if you are sitting Alevel examinations this coming autumn, or in summer of 2021."
Please read further down the thread for specific conditions relating to CAGs/resits for the 2020 cohort applying in 2021
