Oh found this link for a job posting when they must have been looking for the house mom:

"The role of the House Director on the programme is:
1. Veracity, British people have absolutely no sense of sororities, we are aiming to make the programme as true to life as possible.
2. To provide a different tone to the programme, 25 women between 18-22 on screen all the time could become tiring!
3. To mentor the girls, provide support and generally be someone for them to talk to. In each episode we’d like to have a segment in which the House Mother advises and councils the American Sorority Sisters as well as the British Pledges.
The House Mother will not participate in challenges or really any segments except formal dinners attending philanthropy events (but not participating) and her role as an advisor. So in summary we will not set up any situations which would be intended to embarrass our House Mother!"
