Previously only a fridge had to be provided. Now it is a separate fridge and freezer or a fridge freezer. The standard small fridge with a one shelf freezer does not comply with the new requirement. I gather, however, that the problem landlords are facing is that many kitchens just don't have the room for a fridge freezer (or separates) unless you start removing presses and, if the kitchen is very small, this will impact on storage space or counter space and, again, per the guidelines space must be sufficient.
Again per the SF NCT, the lack of a freezer or fridge freezer alone means the property is unrentable. I wonder have SF actually read the Guidelines and the technical specifications which flow from them.
