I've looked into an IT course with Advent Computer Training but need to verify company is genuine/accredited.

The problem is I've been told I can take out a 1 yr interest free commercial loan with Barclays for �5,000 to pay the IT course fee for Advent Computer Training (see Google). However Barclays Business told me they were unaware of this loan & company so I'm now very dubious. how can I check if company is legit or if this is a scam? Citizens Advice couldn't help.
