Thus eliminating much of the housing stock, including my own house. Just the sort of new regulation we need in the middle of a housing crisis.

Ian - you should check your local authority website as even unlicensed HMOs have standards on size, smoke alarms etc that the LA should enforce.

You may be able to argue that the rooms measuring 6.3m2 are OK if there is a living room and or large/kitchen diner which mitigates the small bedroom sizes. The room measuring 4.4m2 is desperately small however and probably completely unsuitable.
My advice would be to ask the Local Authority on their opinion of the suitability of the rooms and house in general for use as a HMO. My guess is that they'll say all rooms are too small and if you let it as a HMO they may serve an Overcrowding Notice prohibiting the use of all rooms as sleeping accommodation.
Room size requirements don't apply to rooms let to single households, so letting on this basis may be the better option.

Yes these rules are coming in to normal houses now Selective Licensing is here to enforce them.
They giving us 18 months notice to kick them out.
Approx 60% of my tenants got to go. But they ain't going, 'cause tenants will revolt. What u kicking me out 'cause I've had an extra kid & one grew up to be over 10. Is that a crime?

Growing up is not a crime, being a landlord is😣.
Get the tenants to tell the council to rehouse them before the will move.

When I left university in the '70s and got my first job, my first accommodation was a box-room about that size in a shared house, and I was quite happy with it. I had few possessions that I needed in my room and there was reasonable living-room space.

Now that I have growed up and accumulated lots of crap, I would not be happy with it, but size alone should not prevent use as a bedroom.
