Section 21 and Compliance: Why Certificates Determine Your Rights

Section 21 of the Housing Act 1988 gave landlords a powerful and simple tool: serve two months' written notice on a tenant and, provided the procedural requirements were met, the tenant had to leave. No need to prove grounds. No need to establish fault. The notice worked because it was served.

The Renters Rights Act 2025 abolished this mechanism entirely. All tenancies are now periodic and all possession claims must proceed through Section 8 with a specific ground. But the compliance obligations that existed as gatekeepers to Section 21 — the requirement to have and serve valid certificates — have not gone away. Understanding why they mattered, and what replaced them, is essential for every landlord.

What Section 21 Was

Section 21 was introduced by the Housing Act 1988 alongside the assured shorthold tenancy (AST), which became the default tenancy for private rentals. The Section 21 mechanism allowed landlords to end a tenancy at the end of the fixed term (or, for periodic tenancies, at any time) by giving at least two months' notice, without needing to establish any fault on the tenant's part.

This was referred to as a "no-fault eviction" because the tenant did not need to have done anything wrong. Landlords used Section 21 to recover properties for sale, for renovation, for a family member to move in, or simply to end a tenancy that was no longer working — without going through the court system to establish grounds under Section 8.

For landlords, Section 21 was a backstop: the knowledge that you could always end the tenancy gave confidence to let. For tenants, it meant security of tenure was limited to the fixed-term period.

The 'Prescribed Information' Gateway

Over time, Parliament added conditions to the service of Section 21 notices. These conditions were known collectively as the "prescribed information" requirements. If any of them were not met before the notice was served, the Section 21 was invalid.

The prescribed information requirements under the pre-abolition law were:

• EPC — provided to the tenant before the tenancy started
• Gas Safety Certificate (CP12) — provided to the tenant before the tenancy started (for new tenancies from 1 October 2015)
• How to Rent guide — the current version provided at the start of the tenancy
• Deposit protection — deposit protected in an approved scheme and prescribed information provided within 30 days of receipt

If any of these documents had not been provided, the landlord could not serve a valid Section 21 notice — even if they had subsequently obtained the missing document. Courts would not allow landlords to "cure" a Section 21 invalidated by failure to serve prescribed information by simply providing the document late.

The EICR obligation under the 2020 Regulations was more nuanced: a failure to provide the EICR to the tenant did not technically invalidate Section 21 in the same way under the specific prescribed information rules, but combined with other failures it created serious procedural exposure.

EPC — Must Be Served Before the Tenancy

The requirement to provide an EPC to tenants predates the specific Section 21 gateway rules. Under the Energy Performance of Buildings (England and Wales) Regulations 2012, landlords must make an EPC available to prospective tenants at the earliest opportunity — specifically, before they enter into a tenancy agreement.

What this means in practice:

• The EPC must be valid (within 10 years) and rated at least E
• It must be provided to the prospective tenant before they sign the tenancy agreement
• It must be provided physically or electronically — there is no requirement for acknowledgement

Failure to provide the EPC meant the Section 21 notice was invalid under pre-abolition law. Under the new regime, failure to have a valid EPC is an independent breach of MEES regulations with a penalty of up to £5,000.

Gas Safety Certificate — Must Be Served

The Gas Safety (Installation and Use) Regulations 1998 require landlords to provide new tenants with a copy of the current Gas Safety Certificate before they move in. This is an independent legal obligation — it does not depend on Section 21 law.

Under the old Section 21 regime, providing the Gas Safety Certificate was one of the specific prescribed information requirements. A landlord who had not provided the CP12 before the tenancy started could not serve a valid Section 21 notice for that tenancy — not even after providing the certificate late.

Under the new regime, a landlord who does not have a valid Gas Safety Certificate faces criminal prosecution, an unlimited fine, and potential imprisonment. The Section 8 grounds for possession do not specifically require a valid CP12 — but a landlord without one is in a very poor position in any legal proceedings, and is exposed to HSE enforcement independently of any possession action.

Get your gas safety certificate booked and provided to your tenant before the tenancy starts. There is no sensible reason not to.

EICR — Must Be Served Before or At Start

Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, landlords must provide a copy of the EICR to new tenants before or at the time they move in. This is a standalone legal requirement with a civil penalty of up to £30,000 for breach.

The EICR must be:

• Current (within 5 years, or the interval specified in the previous EICR if shorter)
• Satisfactory (no outstanding C1 or C2 defects)
• Provided to the tenant at or before the start of the tenancy

Under pre-abolition law, not having provided an EICR could create difficulties in a Section 21 possession case even if it did not technically invalidate the notice under the prescribed information rules. Judges could and did take a dim view of landlords who appeared non-compliant with their safety obligations.

Under the new possession regime, the same reputational and legal problem applies. A landlord seeking possession under Section 8 who is simultaneously non-compliant with their electrical safety obligations is unlikely to receive sympathetic treatment in court.

Your EICR should be booked, completed, and provided to the tenant before the tenancy commences.

Deposit Protection

Deposit protection is a separate but related gateway under the old Section 21 law. If the landlord received a deposit from the tenant and did not:

1. Protect it in a government-approved tenancy deposit scheme within 30 days
2. Provide the prescribed information about the scheme to the tenant within 30 days

Then the Section 21 notice was invalid — and the tenant could claim up to three times the deposit as a penalty.

Under the Renters Rights Act 2025, the deposit protection obligations remain in force for tenancies with deposits. The automatic invalidation of the Section 21 notice is no longer relevant, but the financial penalty (up to 3× deposit) and the reputational damage of failing to protect a deposit remain.

How a Missing Certificate Invalidated Section 21

Under the old law, the mechanism worked as follows:

1. Landlord fails to provide EPC (or Gas Safety Certificate, or How to Rent guide) before the tenancy starts
2. Landlord later serves a Section 21 notice
3. Tenant raises the prescribed information failure as a defence at court
4. Court dismisses the possession claim because the Section 21 was not validly served
5. Landlord must re-serve — but if the prescribed information failure was not cured before re-service (e.g., a Gas Safety Certificate that was never provided at the start), the court may find it still invalid

This created a significant and expensive trap for landlords who had not kept their compliance documentation in order. A single missing document could cost months of legal proceedings and thousands of pounds in court fees and lost rent.

The Transition to the New Regime

The Renters Rights Act 2025 replaced fixed-term ASTs with periodic tenancies and abolished Section 21. The transition arrangements affected:

• Existing fixed-term tenancies: These transitioned to periodic tenancies on the commencement of the relevant provisions
• Section 21 notices already served: Transitional provisions allowed pending Section 21 cases to proceed for a limited period
• New tenancies from commencement: All new tenancies are periodic from the start and Section 21 is not available

The result is that landlords can no longer use the threat of Section 21 as leverage, cannot end a tenancy without a Section 8 ground, and must plan for possession proceedings that are more contested and more subject to judicial scrutiny.

In this environment, maintaining impeccable compliance documentation — current EICR, current gas safety certificate, current EPC, correctly protected deposit — is more important than ever. Not because it unlocks a possession mechanism, but because it is the foundation of a legally sound tenancy and the best protection against enforcement action.

What to Do If You Have a Non-Compliant Tenancy

If you discover that you have a tenancy where compliance documents were not served correctly:

1. Get the missing certificate immediately. For an EICR that was never obtained, book one urgently. For a Gas Safety Certificate that has lapsed, arrange an inspection. For an EPC, book an assessment.

2. Serve it on the tenant as soon as you have it. Document the date of service and keep a copy of the acknowledgement.

3. Update your records. A compliance spreadsheet with renewal dates for each property is invaluable.

4. Seek legal advice if you believe a compliance failure has already affected your possession rights or if you are facing a claim by a tenant. Landlord law solicitors can advise on your specific position.

5. Do not repeat the failure. Every new tenancy and every renewal is an opportunity to get the compliance process right from the start.
