The clock is ticking for landlords in England. Under the Renters’ Rights Act 2025, Section 21 “no-fault” evictions will be officially abolished on 1 May 2026.
For property owners looking to regain possession of their investments, this means the window to serve a valid Section 21 notice is closing rapidly. The absolute final day you can serve a notice is 30 April 2026. Furthermore, you must issue court proceedings based on that notice by 31 July 2026.
Historically, if a landlord made a mistake on a Section 21 notice, a judge would strike it out and the landlord would simply have to serve a fresh one. Today, making an error is a much more serious issue. If your notice is deemed invalid after 1 May, you lose the ability to use Section 21 entirely and must navigate the new, evidence-heavy Section 8 grounds.
To protect your property rights before the deadline, you must ensure your paperwork is flawless. Here are the most common mistakes landlords make during the Section 21 process.
1. Mishandling the Tenancy Deposit
Failing to properly protect a tenant’s deposit is the quickest way to invalidate a Section 21 notice. By law, you must place the deposit in a government-backed Tenancy Deposit Protection scheme within 30 days of receiving it.
Crucially, you must also provide the tenant with the Prescribed Information relating to that scheme within the same 30-day window. If you missed this deadline, you usually cannot serve a valid Section 21 notice unless you return the deposit to the tenant in full first.
2. Forgetting Mandatory Compliance Documents
A Section 21 notice is only valid if the landlord has complied with strict health, safety, and informational regulations at the start of the tenancy. Common oversights include failing to provide the tenant with:
- A valid Gas Safety Certificate before they moved in.
- An up-to-date Energy Performance Certificate (EPC).
- The government’s current ‘How to Rent’ guide at the time the tenancy commenced.
If you attempt to serve a Section 21 notice without having provided these documents, the court will automatically reject your possession claim.
3. Getting the Notice Dates Wrong
The rules surrounding notice periods are rigid. A Section 21 notice must give the tenant a minimum of two full months to vacate the property. A surprising number of landlords miscalculate this by failing to account for postal delivery times. If you send the notice by first-class post, you must add extra days to ensure the tenant receives a full two months of statutory notice from the date the letter actually arrives.
4. Using an Outdated Form
The law requires landlords to use a very specific document known as ‘Form 6A’ to serve a Section 21 notice. Using an older version of the form or simply writing a letter to the tenant asking them to leave, holds absolutely no legal weight. The courts require precise wording and formatting to grant an accelerated possession order.
5. Ignoring Local Authority Licensing
If your property is a House in Multiple Occupation (HMO), or if it falls under a specific local authority selective licensing scheme, it must be properly licensed. Serving a Section 21 notice while operating an unlicensed property is unlawful. Similarly, if the local council has served an Improvement Notice or an Emergency Remedial Action Notice on your property regarding poor living conditions, any Section 21 notice you issue will likely be invalid.
