Before You Serve: The Document Audit That Decides Whether Your Section 21 Notice Survives

Possession claims fail for unglamorous reasons. In county court, the fatal defect is rarely a dramatic dispute over conduct; it is a gas safety certificate that was issued eleven days late, or a deposit that was protected a fortnight after the deadline. Section 21 is a paperwork-dependent remedy, and the courts apply the requirements strictly. For landlords preparing to regain possession, the sensible course is a forensic audit of the file before the notice is drafted — not after the claim is struck out.

Step One: The Gas Safety Record

A Landlord Gas Safety Record must be in force at the start of the tenancy and renewed every twelve months. Since the Tame v Empire Property Investments decision, the courts have taken the view that a certificate provided after the tenancy begins cannot retrospectively cure the defect — the record must have been given to the tenant before the Section 21 notice is served, and the initial certificate must have been issued at or before the tenancy's commencement.

Audit point: confirm the date on the original certificate, confirm each renewal certificate was supplied to the tenant (a dated email or signed acknowledgment is ideal), and confirm no gap exists between expiries.

Step Two: The Energy Performance Certificate

An EPC rated E or above must have been commissioned before the property was first marketed and given to the tenant. The certificate is valid for ten years, so check the expiry date against your tenancy start date. A lapsed EPC at the time of service is a ground for challenging the notice.

Step Three: Deposit Protection Paperwork

Where a tenancy deposit was taken, three things must have happened within 30 days of receipt: the deposit placed with a government-approved scheme (mydeposits, the DPS or TDS), the prescribed information served on the tenant (and any guarantor), and evidence retained of both. If the deposit was returned before service of notice, retain the repayment confirmation — the prescribed information requirements still apply to the period in which the deposit was held.

Step Four: Prescribed Form and Service

The notice itself must be on Form 6A for assured shorthold tenancies in England, with no alterations. Give at least two months' notice in writing, ensuring the notice period ends no earlier than the last day of a periodic tenancy period — a common and avoidable error. Retain proof of service: a signed acknowledgment, or a record of the delivery method used.

Step Five: The Retaliatory and Discriminatory Clauses Check

A Section 21 notice is invalid if it is retaliatory — served because the tenant exercised a statutory right, such as requesting repairs — or discriminatory. If a tenant has raised disrepair complaints, resolve them or document the remedial action taken before serving. Similarly, a landlord who cannot satisfy the 'right to rent' checking regime cannot lawfully rely on Section 21 at all, so confirm your right-to-rent checks were completed and recorded.

Step Six: Licensing and HMO Compliance

If the property requires a licence — selective licensing in certain boroughs, or mandatory/additional HMO licensing — the licence must be in force throughout the relevant period. An unlicensed HMO renders a Section 21 notice invalid. Check your local authority's designation, as boundaries and schemes change.

Renters (Reform) Bill: The Transition Question

The Renters (Reform) Bill proposes abolishing assured shorthold tenancies and Section 21 altogether, replacing them with assured tenancies and expanded grounds for possession. Until it receives Royal Assent and commences, Section 21 remains the operative route for no-fault possession. Landlords should assume a transition window during which existing tenancies will convert, and should treat the current audit discipline as permanent: the documentary standards that underpin Section 21 — gas safety, deposit protection, licensing — will continue to underpin the successor grounds. A clean file now is preparation, not merely compliance.

Final Audit Checklist

• Landlord Gas Safety Record: current, dated correctly, and evidenced as given to tenant
• EPC: valid, rated E or above, copy held
• Deposit: protected within 30 days; prescribed information served and retained
• Form 6A: unaltered, correctly dated, notice period compliant
• Licence (if required): in force
• Right to rent checks: completed and recorded
• No unresolved retaliatory or discriminatory conduct

Possession is a legal process, but it is decided on paperwork. Build the file before you need it.
