You’ve basically got it. Need EPC, once every 10 years(£50), Gas safety cert annually(£60). Smoke alarms. Nothing else required. If you take a deposit, you legally have to lodge it with one of the schemes, which allows tenant to get independent arbitration on retention. I don’t bother with deposit anymore as if I don’t think I trust them with £100k worth of house, £500 deposit isn’t really going to help, and a realistic level of deposit to cover repair costs by a crap tenant would be nearer £3k. Get insurance too, Direct Line do it now, quick, easy and cheap. As for the energy safety certificate, there isn’t a requirement for one, hence there isn’t a standard form like the gas one. Basically though, if bad electrics cause problems, you’re liable, but the same goes if the roof falls on the tenant’s head, so make sure everything is safe. Make records (photos) of when you do visual inspections, and get landlord insurance and you have done more than you need legally and have covered your back.
