Hi kirsty If it was a standard stud wall this wouldn't be providing any structural support to the ceiling above, however as buildings settle over years then floor joists can sit down onto a stud wall and once removed some movement can occur I personally would never add a beam or lintel when taking out a stud wall and it certainly isn't a building regulations requirement. Best thing to do as a start is speak to your builders and see what they say.
