@ Concerned Landlord.
I do feel like I should point out that I am a private landlord too, so I'd you like you to consider my responses in that context.
"Firstly, I have tenants who throw away smoke alarms or remove batteries, batteries missing from carbon monoxide alarm. I have had tenants remove automatic door closers as they think they are a nuisance or wedge them open. I have properties returned with missing fire blankets and fire extinguishers (these are optional to provide). Yet no tenant has ever been prosecuted by a local authority. We put emergency lighting in one property, only to find the tenants did not top up the electricity when they went on holiday. So over the period of a year, the battery got exhausted and the fridge had de-iced and damaged to flooring. Tenants don't take safety seriously."
Frankly, this is why we take an inventory and a deposit. If I install a smoke / CO detector and my tenant is foolish enough to permanently disable it or remove it, then I can simply claim the cost of replacing it from their deposit. Same with auto closers etc. Ultimately, the tenant not taking their own safety seriously is their affair, but it doesn't remove your duty to follow the law.
As for where I stand on the guidance. There's a lot of useful information here:
... and it even says you should go and talk to your local council to find out what local standards are required. Took me all of 1 minute to find.
Sorry chap, but you're talking tosh.
