The count of the number of rooms excludes bathrooms, toilets, halls or landings, and rooms that can only be used for storage. All other rooms (eg example, kitchens, living rooms, bedrooms, utility rooms, integral garages and studies) are counted. If two rooms have been converted into one they are counted as one room. Shared rooms (eg shared kitchens with another flat) are not included.

The number of rooms is used to estimate the size of the property if a floor area has not been provided.
