AST Agreement Compliance Check & Gap Review Guide UK

An Assured Shorthold Tenancy (AST) agreement is the most common type of rental contract in England and Wales. But if it’s missing key clauses or fails to comply with UK housing laws, landlords risk invalid notices, deposit disputes, and costly court battles—while tenants may lose protections they’re legally entitled to.

UK housing law note: Tenancy deposits, eviction routes, and fitness for habitation are shaped by statutes such as the Housing Act 1988, deposit-protection rules, and related consumer fairness standards under the Consumer Rights Act 2015 where terms apply. Information-only — not legal advice.

This guide explains how to audit your AST agreement for compliance with deposit protection rules, notice requirements, repairing obligations, and Energy Performance Certificate (EPC) standards. We’ll cover the five most critical checks, common mistakes that lead to disputes, and how VetroCheck’s AI-powered review can help you spot gaps before they become problems.

Why this housing document can decide your tenancy outcome

Every year, thousands of landlords and tenants in England and Wales face avoidable disputes because their AST agreement doesn’t meet legal requirements. A missing deposit protection certificate, an outdated EPC rating, or an invalid Section 21 notice can derail evictions, delay rent increases, or even force landlords to repay deposits in full.

For landlords, the risks are financial and operational:

• A Section 21 notice can be ruled invalid if the deposit wasn’t protected correctly or prescribed information wasn’t provided—meaning you’ll have to restart the eviction process.
• If your property has an EPC rating below E, you can’t legally rent it out, and local councils can impose fines of up to £5,000.
• Failing to follow the rent increase procedure under the Housing Act 1988 could mean your tenant successfully challenges the rise in court.

For tenants, gaps in the AST can mean:

• Losing protection against unfair eviction if the landlord didn’t serve the correct prescribed information with your deposit.
• Being stuck in a property with unaddressed disrepair because the agreement doesn’t clearly state the landlord’s obligations under the Landlord and Tenant Act 1985.
• Paying more rent than you should if the agreement doesn’t specify how increases must be communicated.

Many of these issues only surface when a dispute arises—by which point, legal fees, stress, and lost time are already mounting. A proactive compliance review of your AST agreement can help you fix problems before they escalate.

Is Your Assured Shorthold Tenancy Agreement in Good Shape?

A legally sound AST agreement should: ✅ Protect the tenant’s deposit in a government-approved scheme and provide the required prescribed information. ✅ Allow valid Section 21 and Section 8 notices by complying with notice periods and procedural rules. ✅ Clarify repairing obligations under the Landlord and Tenant Act 1985, so tenants know their rights and landlords avoid disrepair claims. ✅ Include a lawful rent increase procedure, either via a rent review clause or the statutory process under the Housing Act 1988. ✅ Reference the property’s EPC rating and confirm it meets the minimum energy efficiency standard (MEES).

If your agreement is missing any of these, it may not withstand later scrutiny—or worse, could leave you exposed to fines or legal challenges.

Housing law in plain English (deposits, notices, fitness)

The rules governing AST agreements come from several key UK laws. Here’s what they mean in practice:

Housing Act 1988 (HA1988)

This is the foundation of modern private renting in England and Wales. It introduced Assured Shorthold Tenancies and set out:

• How Section 21 notices (no-fault evictions) must be served.
• The rent increase procedure—landlords can’t just demand more money without following the rules.
• Security of tenure—tenants have the right to stay in the property unless the landlord follows the correct eviction process.

Landlord and Tenant Act 1985 (LTA1985)

This law defines landlords’ repairing obligations. Under Section 11, landlords must:

• Keep the structure and exterior of the property in good repair (roof, walls, drains, gutters).
• Ensure installations for water, gas, electricity, and heating are safe and working.
• Maintain sanitary fittings (toilets, sinks, baths).

If the AST agreement doesn’t reflect these duties, tenants may struggle to enforce repairs.

Housing Act 2004 (HA2004)

This introduced tenancy deposit protection (TDP), requiring landlords to:

• Place deposits in a government-approved scheme (Deposit Protection Service, MyDeposits, or Tenancy Deposit Scheme).
• Provide prescribed information to the tenant within 30 days of receiving the deposit.
• Failure to comply means landlords can’t use Section 21 and may have to repay the deposit plus up to 3x its value in compensation.

Deregulation Act 2015 (DA2015)

This tightened Section 21 rules, making it harder for landlords to evict tenants unfairly. Key changes:

• No "retaliatory eviction"—if a tenant complains about disrepair, the landlord can’t serve a Section 21 notice for 6 months.
• Prescribed form required—landlords must use Form 6A for Section 21 notices.
• Time limits—Section 21 notices can’t be served in the first 4 months of a tenancy.

Tenant Fees Act 2019 (TFA2019)

This banned most tenant fees and capped deposits at 5 weeks’ rent (or 6 weeks if annual rent exceeds £50,000). It also:

• Made it illegal to charge for reference checks, inventories, or admin fees.
• Introduced financial penalties (up to £5,000 for a first offence) for landlords who breach the rules.

Five housing checks landlords and tenants miss

1. Deposit Protection: Was It Done Correctly?

Why it matters: If the deposit wasn’t protected in a government-approved scheme within 30 days, the landlord can’t use Section 21 and may have to repay the deposit plus up to 3x its value in compensation.

What to check in your AST:

• Does the agreement state which deposit scheme was used?
• Is there a deposit protection certificate or reference number?
• Was the prescribed information (scheme leaflet, repayment process) provided to the tenant within 30 days?

Practical tip: Even if the deposit was protected, missing prescribed information can invalidate a Section 21 notice. Keep records of when and how the tenant received the details.

How VetroCheck helps: Our AST compliance review flags missing deposit protection clauses and checks whether the prescribed information requirements are met.

---

2. Section 21 Validity: Can You Actually Use It?

Why it matters: A Section 21 notice is the most common way for landlords to regain possession—but if the AST doesn’t comply with Deregulation Act 2015 rules, the notice will be invalid, forcing you to start over.

What to check in your AST:

• Was the prescribed Form 6A used?
• Was the notice served after the first 4 months of the tenancy?
• If the tenancy started or was renewed after 1 October 2015, was the deposit protected correctly and prescribed information provided?
• Was the property licensed (if required) under a selective licensing scheme?

Practical tip: If the tenant has complained about disrepair, a Section 21 notice served within 6 months may be invalid under retaliatory eviction rules.

How VetroCheck helps: Our review checks whether your AST allows for a valid Section 21 notice and flags potential issues like missing prescribed information.

---

3. Section 8 Grounds: Are the Eviction Reasons Clear?

Why it matters: Unlike Section 21 (no-fault eviction), Section 8 requires a legal ground for possession, such as rent arrears or anti-social behaviour. If the AST doesn’t reference these grounds, the eviction may fail.

What to check in your AST:

• Does the agreement list valid Section 8 grounds (e.g., rent arrears, breach of tenancy, property damage)?
• Are the notice periods correct? (For example, 2 weeks’ notice for rent arrears, 2 months’ notice for other breaches.)
• Is there a break clause (if applicable) allowing early termination?

Practical tip: If the tenant is in 2+ months’ rent arrears, you can use Ground 8 for mandatory possession—but the AST must allow it.

How VetroCheck helps: Our review identifies whether your AST includes valid Section 8 grounds and checks for compliance with notice periods.

---

4. Repairing Obligations: Who Fixes What?

Why it matters: Under the Landlord and Tenant Act 1985, landlords must keep the property in good repair. If the AST doesn’t clearly state these obligations, tenants may struggle to enforce repairs, and landlords risk disrepair claims or retaliatory eviction bans.

What to check in your AST:

• Does the agreement mirror Section 11 of the LTA1985 (structure, heating, water, sanitation)?
• Are there exceptions (e.g., tenant damage, fair wear and tear)?
• Does it specify how repairs should be reported (e.g., in writing, via email)?

Practical tip: If the tenant has repeatedly requested repairs and the landlord hasn’t acted, a Section 21 notice may be invalid under retaliatory eviction rules.

How VetroCheck helps: Our review checks whether your AST clearly defines repairing obligations and flags any gaps that could lead to disputes.

---

5. Rent Increase Procedure: Is It Lawful?

Why it matters: Landlords can’t just demand more rent—they must follow the statutory procedure under the Housing Act 1988. If the AST doesn’t specify how increases work, tenants can challenge them in court.

What to check in your AST:

• Is there a rent review clause (e.g., annual increases linked to inflation)?
• If not, does the agreement allow for statutory rent increases (requiring 1 month’s notice for periodic tenancies)?
• Does it comply with the Tenant Fees Act 2019 (no hidden fees)?

Practical tip: For periodic tenancies, landlords must use Form 4 to propose a rent increase. For fixed-term tenancies, increases can only happen if the AST allows it.

How VetroCheck helps: Our review checks whether your AST includes a lawful rent increase procedure and flags any clauses that could be challenged.

Housing mistakes that trigger disputes and costs

1. Missing Prescribed Information for Deposits

What happens: The landlord protects the deposit but forgets to give the tenant the prescribed information (scheme leaflet, repayment process). Consequence: The Section 21 notice is invalid, and the landlord may have to repay the deposit plus up to 3x its value in compensation.

2. Outdated EPC Rating Below E

What happens: The property has an EPC rating of F or G, but the AST doesn’t mention it. Consequence: The tenancy is illegal, and the landlord could face a £5,000 fine from the local council.

3. Invalid Rent Increase Clause

What happens: The AST allows rent increases but doesn’t specify how or when they can happen. Consequence: The tenant challenges the increase in court, and the landlord has to refund the extra rent or restart the process.
