Just so there's no misunderstanding, it seems the actual amounts of rents are now on record:

According to his expenses claims, from April 2004 Mr Laws claimed £700 a month to cover the rent in his partner's flat. The MP's monthly rent rose to £780 at the beginning of January 2005, and then to £920 in February 2006.

He also claimed for telephone bills, maintenance and cleaning at the flat.
