In 2000 there were 41 LPAM licences and 35 induction loop licences.
"For the first time, the number of LPAMs in issue now exceeds the number of induction loop licences."
"As Table 2 above illustrates, there were still 35 induction loop services licensed by the Authority as at 31 December 2000, but this total is gradually decreasing. There have been only three new applications since 1991, and the last was in 1996. Compared to freelyradiating transmission systems, the internal cabling required for induction loop systems can be expensive to install and maintain, and funding constraints in both the health service and higher education have made host establishments highly reluctant to pay for new systems, or the maintenance of existing ones. The introduction of low-powered AM licences has provided existing induction loop services with the opportunity to broadcast using a much more cost-effective form of transmission, and a number of licensees operating on induction loop have 'upgraded' to low-powered AM since the introduction of that category of licence."

Crush Hatfield is on 1278, University of Herfordshire. Can pick them up here 18 miles away. British DX Club 2015 also has Universities of Bradford, Surrey, York, Nottingham, Bath, Western England, Chester, East Anglia and Warwick on LPAM licences.
The BDXC doesn't list the inductive loop licences but looking at the Long Term Restricted Licence list at Ofcom and checking with a 2013 list that's still there where they were listed as Induction Loop and checking on the latest list, where they appear as AM rather than LPAM, could only see a couple on a quick comparison.
University Radio York says
"We are broadcasting on AM radio all across campus on 1350KHz Medium Wave. So what are you waiting for? Ask your parents if you can have their old boom box, and listen like it's 1989."
They were the first legal independent radio station. "in theory we were only receivable on the university campus. (I think we had one reception report from Sweden/Poland before we got the loop aerials sorted out properly)."

Cam FM for the Universities of Cambridge and Anglia Ruskin is on a community radio licence, maybe other universities?
