Until the end of this year, IPF world records can be broken at National level and international level events so long as the judging criteria is met. After Jan.1 (I think) IPF records can only be set at International and Regional level meets.
I'm not familiar with how the British associations are affiliated and what level this was, but assuming this is an IPF affiliate, if this qualified as a National event (I don't know), the record may count. But I doubt their University contests are National level.
Either way, that was one hell of a pull and he may well be the first (and only for a really long time) to hold the IPF world deadlift record if he competes at the World championships (or a regional event) next year.
