Hi, I am nearly about to finish a full refurb of two flats. Electrics, new boilers and central heating systems, new bathrooms, new kitchens, new window and doors. They are ground floor victorian and were in a shocking state. They each have an independent front and back door. Can anyone answer do I need to fit internally fire rated doors to a) all rooms b) no rooms or c) just the kitchen? The Bedroom to one is by the front door and to the other in the middle off a corridor leading to the kitchen. Each kitchen has it's own back door. They are one bedders each so won't be sharers (except couples) nor HMO. Grateful for any advice out there! Thanks.
