Rent Arrears Process for Letting Agents

From first missed payment to Section 8 notice — the complete arrears escalation procedure for UK letting agents, updated for the Renters' Rights Act 2025 and the new 3-month Ground 8 threshold.

Rent arrears is the most common crisis a letting agent manages on a landlord's behalf. Handled badly — too slow, too aggressive, or without a documented process — it creates liability for both agent and landlord. Handled well, most cases resolve without reaching court.

This guide sets out a standard escalation procedure from day one of a missed payment through to Section 8 notice. It reflects the rules that apply from 1 May 2026 under the Renters' Rights Act 2025, including the new 3-month Ground 8 threshold.

RRA 2025 change:Ground 8 (mandatory possession for rent arrears) now requires 3 months' arrears — increased from 2 months. This applies to all notices served from 1 May 2026, regardless of when the tenancy started.

Step-by-step escalation

The timeline below assumes monthly rent. Adjust proportionally for weekly or fortnightly tenancies.

Day 1Rent due — payment not received
  • Do not contact immediately. Most missed payments self-resolve within 1–3 days (bank processing delays, forgotten standing orders).
  • Note the date in your system. Start the clock.
Day 3–5First chaser
  • Friendly text or email: "Your rent of £X was due on [date]. Please let us know if there's a problem."
  • Keep the tone neutral — this resolves the majority of cases.
  • Log the contact in your file.
Day 8–10Second chaser
  • Firmer communication — phone call if possible, followed by written record.
  • Make clear that continued non-payment will be escalated.
  • Establish whether the tenant has contacted DWP, employer, or is seeking benefit support.
Day 14Formal written notice
  • Letter or email clearly stating: amount owed, date payment was due, deadline for payment or contact.
  • Inform tenant that you will notify the landlord and that legal action may follow.
  • Send by email AND recorded post — you need a delivery record.
Day 21Notify landlord
  • At 3 weeks' arrears, notify the landlord client in writing with: amount owed, contact log so far, your recommendation for next steps.
  • Get written instruction to proceed before taking legal steps — this protects you and the landlord.
1 monthConsider payment arrangement
  • If the tenant engages but cannot pay in full: offer a written payment arrangement with specific dates and amounts.
  • Document the arrangement. Make clear that breach of the arrangement triggers immediate escalation.
  • Payment arrangements pause possession proceedings — only offer if the landlord agrees.
A payment arrangement is not a legal obligation. It is a commercial decision.
2 monthsPre-action steps
  • Two months' arrears = eligible for Ground 10 (discretionary). Court has discretion to grant or refuse.
  • Send a pre-action letter: this is a formal notification that possession proceedings may be commenced.
  • Check: is deposit protected? Is gas safety cert current? Is EICR valid? Non-compliance weakens your position.
3 monthsSection 8 — Ground 8 eligible
  • Three months' arrears = eligible for Ground 8 (mandatory possession). Court must grant if arrears exist at hearing.
  • Instruct solicitor or use LetSense to generate Form 3A — the mandatory notice form under RRA 2025.
  • Serve notice: 4 weeks' notice required for Ground 8.
  • Arrears must still be 3 months or more at the court hearing — any payment reducing below threshold loses the mandatory ground.
Ground 8 threshold increased from 2 months to 3 months under RRA 2025 (from 1 May 2026).
Post-noticeCourt proceedings
  • After notice period expires: file possession claim at county court.
  • Attach evidence: rent statement, copy of tenancy agreement, proof of service, copy of notice.
  • First hearing typically 4–8 weeks after filing.
  • If tenant does not attend and arrears are confirmed: possession order usually granted.

Which Section 8 grounds apply?

Always include all applicable grounds on the same Form 3A notice. If you omit a ground, you cannot rely on it later.

What invalidates a Section 8 notice

Wrong form

From 1 May 2026, only Form 3A is valid. Using the old Prescribed Form 3 or a generic template will result in the notice being struck out.

Wrong notice period

Different grounds require different notice periods. Ground 8 requires 4 weeks. Getting this wrong makes the notice defective — you must start again.

Unprotected deposit

If the deposit was not protected within 30 days of receipt, the landlord may face a penalty claim in the same proceedings. More practically, it signals non-compliance to the court.

Expired compliance documents

An expired gas safety certificate or EICR does not automatically invalidate a Section 8 notice (unlike Section 21 requirements) — but it weakens the landlord's position on discretionary grounds and invites counter-claims.

Arrears fall below threshold before hearing

For Ground 8, if the tenant pays enough to bring arrears below 3 months before the court hearing, the mandatory ground fails. Courts will not grant possession on Ground 8 in this situation. Grounds 10 and 11 remain available but are discretionary.

Proof of service issues

You must be able to prove the notice was served on the tenant. Email with read receipt, recorded post, or hand delivery with a witness. If you cannot prove service, the notice period has not started.

LetSense sends arrears chasers automatically.

Set your grace period and chaser schedule once. LetSense sends escalating reminders and prompts you to serve notice when the arrears threshold is reached.

Frequently asked questions

What is the difference between Ground 8, Ground 10, and Ground 11?

Ground 8 is mandatory: if the tenant owes 3 months' rent at the time of notice and at the court hearing, the court must grant possession. Ground 10 is discretionary: the tenant owes some arrears (less than 3 months). The court can grant or refuse based on circumstances. Ground 11 is also discretionary: the tenant persistently pays late, even if not currently in arrears. Most arrears cases use Ground 8 plus Grounds 10 and 11 as fallback grounds on the same Form 3A notice.

What is Ground 8A and when does it apply?

Ground 8A is a new ground introduced by the Renters's Rights Act 2025. It applies when a tenant has been in at least 3 months' arrears on three or more separate occasions in the last 36 months — even if they have since paid down. Unlike Ground 8, the current arrears balance does not need to be at 3 months at the hearing. This is significant: a tenant who consistently clears arrears just before a hearing to defeat Ground 8 may still be vulnerable to Ground 8A.

Can we send a Section 8 notice on behalf of a landlord?

Yes, and it is standard practice for fully managed letting agents to serve Section 8 notices as agent of the landlord. The notice must be served in the landlord's name, but agents commonly draft and serve it. The critical thing is that you use the correct form (Form 3A from 1 May 2026), the correct notice period for each ground, and that you can prove service. If the notice is defective, the possession claim will fail.

What if the tenant makes a partial payment during the notice period?

Accept it — refusing payment creates a separate legal problem. However, a partial payment does not cancel the notice unless it brings arrears below the 3-month threshold for Ground 8. Monitor the arrears balance carefully: if the tenant pays enough to drop below 3 months before the court hearing, you lose Ground 8. Grounds 10 and 11 remain available. This is why including multiple grounds on the same notice is standard practice.

Should we always pursue possession, or are there alternatives?

Possession is the last resort, not the first tool. Payment arrangements, benefit referrals, and mediation resolve many arrears cases without court. Courts also consider the proportionality of possession proceedings, particularly for discretionary grounds. The practical calculus: possession proceedings take 3–6 months and cost the landlord £1,000–3,000 in legal and court fees. A working payment arrangement with a tenant who can pay is often the better commercial outcome.

How does deposit protection affect a Section 8 claim?

Directly. If the landlord has not protected the deposit in a government-approved scheme and served the Prescribed Information within 30 days, the court cannot award Ground 2 compensation — and the landlord may face a penalty of 1–3× the deposit. More critically, an unprotected deposit signals to a judge that the landlord has not met their basic statutory duties, which affects credibility on discretionary grounds. Always verify deposit compliance before filing.
