Ground 8a Persistent Arrears UK 2026 — Complete Landlord Guide to the New RRA 2025 Mandatory Possession Ground

Conditions for Ground 8a — what the landlord must establish

Ground 8a is made out where all of the following conditions are satisfied at the time the court considers the possession claim:

• 3 or more qualifying arrears episodes: The tenant must have been at least 2 months in arrears (calculated by reference to the rent due under the tenancy) on at least 3 separate occasions in the preceding 3-year period. Each episode must be a distinct period of being 2 months or more in arrears — a continuous period of arrears counts as one episode, not multiple. The 3-year look-back period runs backwards from the date of the court hearing
• 'At least 2 months in arrears' — calculation: The arrears threshold for each qualifying episode is the same as Ground 8 — the tenant must owe at least 2 months' rent at the point the episode is assessed. For a monthly tenancy at £1,000/month, the tenant must owe at least £2,000. Note: this is the same threshold as Ground 8 — but for Ground 8a, the question is whether this threshold was reached at any point during the episode, not whether it is reached at the hearing date
• Clearing arrears does not defeat Ground 8a: This is the critical distinction from Ground 8. Under Ground 8, if the tenant clears the arrears (or reduces them below the 2-month threshold) before the hearing, the mandatory possession ground fails. Under Ground 8a, once the 3 qualifying episodes have occurred, clearing the arrears does not prevent the court from making a possession order. The ground looks back at history, not at the current arrears level
• The 3-year look-back period: The look-back period is 3 years running back from the date of the hearing. Only episodes within this 3-year window count. Where a landlord is dealing with a long-term problem tenant who has been managing arrears for 5 years, only the most recent 3 years of arrears history is relevant
• Mandatory ground: Ground 8a is mandatory — where the court is satisfied the conditions are met, it must make a possession order. The court has no discretion to refuse or suspend the order on the basis that the tenant has cleared the arrears by the hearing date or that it would be reasonable to give the tenant another chance. This mandatory nature is what makes Ground 8a significantly more powerful than the discretionary Ground 10 and Ground 11 arrears grounds

Notice period and procedure — using Ground 8a with Section 8 Form 3

The procedure for Ground 8a is the same as for other Section 8 grounds — the landlord serves a Section 8 notice (Form 3, current RRA 2025 version) specifying Ground 8a, then issues proceedings once the notice period has expired:

• 4-week minimum notice period: The Section 8 Form 3 notice specifying Ground 8a must give at least 4 weeks' notice before the landlord can issue possession proceedings. This is shorter than the 2-month notice required for Ground 8 — reflecting the fact that Ground 8a involves established persistent non-payment, making a shorter notice period appropriate
• Notice period vs Ground 8 — practical implications: Because Ground 8a has a 4-week notice period (vs 2 months for Ground 8), a landlord can issue proceedings under Ground 8a significantly faster than under Ground 8 alone. This is particularly useful where the tenant is approaching the 3-qualifying-episode threshold — the landlord can serve the notice immediately when the 3rd episode is confirmed
• Using Ground 8a alongside Ground 8 and Grounds 10/11: Landlords should routinely specify Ground 8a alongside Ground 8 (where the current arrears are 2 months or more at notice date) and Grounds 10 and 11 (discretionary arrears grounds) in the same Section 8 Form 3. This provides alternative bases for possession where Ground 8 fails (because the tenant clears down) but Ground 8a succeeds (because 3 episodes have occurred); or where Ground 8a fails but Ground 10/11 may support a discretionary possession order
• Evidence of the 3 qualifying episodes: The Form 3 notice should state the facts relied on for Ground 8a — specifically identifying each of the 3 qualifying arrears episodes (dates and amounts). At the hearing, the landlord must be prepared to evidence each episode from the rent account records. A detailed rent account printout (from a property management system or bank records) showing the dates and amounts of each arrears episode is essential
• Timing of service — when does the 3rd episode occur?: The landlord cannot serve a Ground 8a notice until the 3rd qualifying episode has occurred. The landlord should track arrears episodes carefully and serve the notice as soon as the 3rd episode is confirmed (i.e., as soon as the outstanding rent reaches the 2-month threshold for the 3rd time in the 3-year window)

Documenting arrears episodes — evidence requirements for Ground 8a

Ground 8a depends entirely on historical arrears evidence. Without clear documentation of each qualifying episode, the landlord cannot establish the ground at the hearing:

• What constitutes a 'qualifying episode': Each episode is a distinct period during which the outstanding rent reached or exceeded the 2-month threshold. The episode begins when the arrears first reach 2 months and ends when the arrears fall below 2 months (whether by payment or by partial payment). A single continuous period of arrears lasting 6 months counts as one episode — not three
• Rent account records: The primary evidence is a rent account statement showing: (a) each rent due date and the amount due; (b) each payment made and the date; (c) the running arrears balance; (d) the dates when the balance reached and fell below the 2-month threshold. Property management software typically generates this automatically. For manual records, a spreadsheet with date, rent due, payment received, and running balance columns is sufficient
• Contemporaneous documentation: Where a landlord issued demand letters, notices, or emails at each arrears episode, these are useful corroborating evidence. Keep copies of all arrears-related correspondence — emails, letters, WhatsApp messages — with dates. This contemporaneous documentation supports the landlord's evidence if the tenant disputes the arrears history
• Episode dating across tenancy transitions: Where the tenancy has been assigned or the tenant has changed, the 3-year look-back period applies to the current tenancy. For Ground 8a, the arrears episodes must be under the same tenancy — arrears under a previous tenancy at the same property with a different tenant do not count

Ground 8a vs Ground 8 — when to use each and combined strategy

Ground 8a and Ground 8 address different factual scenarios. Understanding when to use each (and when to combine them) is key to effective use of the Section 8 regime:

• Ground 8 — use when: The tenant currently has 2 months or more arrears AND you have served the correct notice AND the arrears remain at or above 2 months at the hearing date. Ground 8 has a 2-month notice period but is defeated if the tenant clears the arrears before the hearing. Ground 8 is the appropriate ground for straightforward, serious rent arrears cases where the tenant is unlikely to clear the debt before the hearing
• Ground 8a — use when: The tenant has a history of persistent non-payment — falling 2+ months into arrears on 3+ occasions in the preceding 3 years — even if the arrears are currently cleared or below the 2-month threshold. Ground 8a has a 4-week notice period and cannot be defeated by clearing the arrears. Ground 8a is the appropriate ground for the 'tactical clearance' problem
• Combined notice strategy: Specify both Ground 8 (where current arrears are 2 months or more) and Ground 8a (where 3 qualifying episodes have occurred in the preceding 3 years) in the same Section 8 Form 3 notice — alongside Grounds 10 and 11 as alternative discretionary grounds. This provides the strongest possible basis for possession: if Ground 8 is defeated by payment, Ground 8a cannot be. If Ground 8a conditions are not yet met, Ground 8 may succeed
• Guarantor liability under Ground 8a: Where the tenancy has a guarantor, the guarantor is liable for the arrears established by each qualifying episode (if the guarantee is broadly drafted to cover the tenancy throughout its term). A Ground 8a possession order based on persistent arrears does not extinguish the guarantor's liability for the arrears accumulated during the qualifying episodes — the landlord can pursue the guarantor for the arrears debt even after obtaining possession
