renovation till jul 2020? wow that is super long time. around 3 months if vp on Mar 2020.

inform your landlord to grant you a 6m extension, afterwards then u can move out with deposit. ask your landlord to find a tenant in 6 month so that he can make your work easier.

but anyway you need to refer back the tenancy agreement which you have signed in the past 2 years.

Better safe than sorry.
