Permission to appeal has been refused by the Supreme Court in the landmark decision of Trecarrell House Limited v Rouncefield on the issue relating to s21 and service of a gas safety certificate.
The Supreme Court opined on the application as not being a point of general public importance.
Essentially, as the law now stands, late service of a gas safety certificate does not prevent a landlord from serving a section 21 notice on their tenant, provided the certificate has been given to the tenant before service of the section 21 notice.
Whilst landlords can breathe a sigh of relief in this case, advice remains the same; always serve the correct documents prior to the tenancy agreement being signed.
