Can late paperwork invalidate a Section 21 notice?
Yes, in some situations it can. Serving a Section 21 notice without first delivering the correct documentation, such as an Energy Performance Certificate or a Gas Safety Certificate, could make the notice invalid. Whether the paperwork timing affects the outcome depends on the document involved and when it was delivered. Landlords managing Assured Shorthold Tenancies must take document timing seriously.
Here's What We Have Covered In This Article
What are the prescribed documents required for a valid Section 21?
What must landlords give tenants?
Before issuing a Section 21 notice under an Assured Shorthold Tenancy, landlords must serve:
-
A valid Energy Performance Certificate (EPC)
-
A current Gas Safety Certificate (CP12)
-
The latest ‘How to Rent’ guide in printed form or as an emailed PDF
These prescribed documents are required under the Deregulation Act 2015. Failing to deliver them in the proper sequence or timeframe could render a notice void.

Does a late EPC count for Section 21 notices?
Is late delivery of an EPC a problem?
Courts are usually more lenient about EPC delivery. If the certificate is served before the Section 21 notice, even if it was missed at the start of the tenancy, it generally satisfies the requirement. For landlords with Assured Shorthold Tenancies in NW London, it is essential to confirm EPC delivery before starting the notice process.
