In terms of these schools, one accreditation is fine, and another wouldn't actually add any incremental value.
In any case, if I were you I would narrow it down by your career goals and geographic preference. Obviously Leicester is relatively close to London, and I'd imagine if you went there you could take advantage of the proximity to network, etc.
