Cyflawnir y nod o roi sicrwydd ychwanegol i ddechrau drwy ymestyn y cyfnod hysbysu byrraf cyn y ceir rhoi hysbysiad adran 173 o dan Ddeddf 2016 (sy'n cyfateb i hysbysiad adran 21 ar hyn o bryd o dan Ddeddf Tai 1988) o ddau fis i chwe mis.  Caiff landlordiaid eu hatal hefyd rhag rhoi hysbysiad o'r fath am o leiaf chwe mis ar ôl y dyddiad meddiannu, sy'n golygu y bydd gan y rheini sy'n rhentu eu cartref o leiaf 12 mis o sicrwydd deiliadaeth o ddechrau eu contract (mae hyn yn dyblu hyd y cyfnod sicrwydd presennol).  Bydd darpariaethau pellach hefyd yn sicrhau na all landlordiaid roi hysbysiadau 'tybiannol' treigl rhag ofn, sy'n gallu tanseilio'r sicrwydd hwnnw y dylai'r rheini sy'n rhentu cartref ei fwynhau.
This additional security will primarily be achieved by extending the minimum notice period for issuing a section 173 notice under the 2016 Act (the equivalent of the current section 21 notice under the Housing Act 1988) from two months to six months.  Landlords will also be prevented from issuing such a notice until at least six months from the date of occupancy, meaning that those renting their home will have a minimum of 12 months security of tenure from the outset of their contract (representing a doubling of the current position).  Further provisions will also ensure that landlords are unable to issue rolling ‘speculative’ notices on a ‘just in case’ basis, which can undermine the sense of security that those renting a home should be able to enjoy.
