Thumb turn locks required on exit doors and bedroom doors

I take it we talking about HMO properties if so yes you need a thumb turn lock on exit doors or an equivalent, I would suggest a mortice type lock with a thumb turn inserted for easy entry and easy and quick exit on bedrooms and entrance doors and exit doors.

Yes I agree, if the property is hmo, multi occupancy then its wise to have a euro thumb turn on all doors. Some councils are stricter than others on this but yes it Is legal. As far as the insurance companies they say it has to be a 5 lever, british standard mortice lock to have cover, this is wrong if the door is a double glazed upvc or composite door. A British standard 3 star euro cylinder could be fitted with or without a thumbturn and they would be happy

It’s not law to fit thumbturn locks but it’s advised.

Door locking Exit/Entry Doors for HMO’s Wooden or metal doors All exit doors recommend a 5 lever mortise lock key to BS 8621 Standards operated from outside by a key but thumb turn operated from inside the house. Recommend a second lock to the exit doors at a height of a third from the top of the door – a rim latch lock (Yale lock) this will allow the door to be locked shut when closed to prevent unlawful persons access without the use of a key. PVCu & Composite Doors – these will usually have a factory fitted multipoint locking system with a Euro profile lock, operated by key entry from outside and thumb turn operation from inside the house. It is difficult to fit additional locks to these doors, recommend the door be fitted with a split spindle so the door can only be opened from the outside with a key.

If your property is a (HMO) home of multiple occupants. all doors need thumb turns for fire regulations.

If the property is an HMO - then yes thumb turns for fire regulations, however if it is a residential let then no, this is not legally required.
