Holiday rental marketplace Snaptrip has revived the website, which was closed in August alongside Super Break when its parent company Malvern Group collapsed.
Snaptrip acquired the website domain and digital assets from Secret Escapes, which in turn had bought them after the collapse.
The new LateRooms website, which launched on 3 December, is currently using Booking.com to power its search.
A spokesperson said the potential for new partnerships would be reviewed over the next 6 to 12 months.
Snaptrip is owned by Rest Easy Group, alongside other brands such as Last Minute Cottages and iknow-uk.com.
