Required certificates and timings

I am looking for a complete list of certificates a landlord needs to do AND the timing e.g. yearly.
I know of the carbon monoxide certificate and I think that’s yearly??? Also the gas safety certificate…again yearly??? Now, the electricity safety certificate for new tenancies from 1 June 2020 - again yearly? Then the legionnaires disease - is that a checklist? Only once Are there any more? Thank you!
