Section 8 Ground 13 (deterioration of the dwelling): the tenant defence walkthrough (2026)

A Section 8 notice citing Ground 13 lands differently from one citing breach of tenancy. Ground 12 is usually pleaded on conduct — pets, occupants, alterations. Ground 13 is pleaded on damage — a wall, a kitchen, a carpet, a garden, a window. The landlord points at physical deterioration and says: you did this, and it is enough to justify the loss of the home. In practice, the ground is harder to make out than it looks. Fair wear and tear quietly defeats a large proportion of poorly-evidenced claims. The "another person residing" line introduces a reasonable-steps test that lets a careful tenant escape liability for damage they did not personally cause. And the landlord's own repair obligations under sections 11 and 9A mean a Ground 13 claim built on damage that is actually disrepair tends to fall apart.

This walkthrough is for a tenant who has received a Section 8 notice citing Ground 13. It covers what the ground says, the procedural attack on the Form 6A, the fair-wear-and-tear doctrine, the "another person residing" line, the reasonableness test, the crossover with the landlord's own s.11 and s.9A obligations, and a templated letter requesting particulars of the alleged deterioration. Ground 13 is distinct from Grounds 8, 10 and 11 (rent arrears, covered separately), Ground 12 (general breach, covered yesterday), and Ground 14 (anti-social behaviour, covered 2026-05-13).

What Ground 13 actually says

Ground 13 of Schedule 2 to the Housing Act 1988 reads, in essence: the condition of the dwelling or any common parts has deteriorated owing to acts of waste by, or the neglect or default of, the tenant or any other person residing there. Where the deterioration was caused by another person, the ground only applies if the tenant has not taken such steps as he or she ought reasonably to have taken for that person's removal.

Three things must be true: actual worsening of the physical condition; caused by waste, neglect or default (all of which imply unreasonable conduct); and caused by the tenant, or by a residing person the tenant has not reasonably tried to remove.

Ground 13 is discretionary. A mandatory ground (Ground 8 arrears at threshold, Ground 1A owner-move-in, Ground 7A serious anti-social behaviour) gives the judge no choice once proved. A discretionary ground requires the judge to be separately satisfied that it is reasonable in all the circumstances to make a possession order. That reasonableness test does the heavy lifting in Ground 13 cases.

The Renters' Rights Act 2025, in force since 1 May 2026, did not change the substance of Ground 13. With Section 21 abolished, landlords who would previously have fallen back on no-fault eviction must now plead a real ground. Ground 13 is one of the grounds they reach for when the relationship has soured around the property's condition, and the quality of the pleading is, in many cases, weak.

Waste, neglect and default — what they actually mean

The three causes of deterioration in Ground 13 are technical concepts inherited from older landlord-and-tenant law. The shorthand: waste is active damage — punching holes in walls, ripping out fittings, smashing a window. Neglect is failure to take reasonable care — letting a leak run for months without reporting it, allowing pets to damage carpets without intervening, leaving rubbish to build up so vermin arrive. Default is breach of a duty under the tenancy or at common law — failing to ventilate, failing to keep the property reasonably clean, failing to allow access for repairs that then worsened.

All three require unreasonable conduct. Honest accidents do not count. A glass dropped on a hob, a single iron mark on a carpet, a cracked basin from normal use — these are not waste, neglect or default. They are mishap or, more commonly, fair wear and tear.

The procedural attack on the Form 6A

Ground 13 cases — like all Section 8 cases — are won on documents before they reach the merits. The two key documents are the Form 6A (the prescribed Section 8 notice) and the particulars of claim if a claim has been issued on the N5.

On the Form 6A, check: tenant names (all joint tenants, exactly as on the agreement — a missing tenant is fatal); property address (exactly as on the agreement); grounds cited (is Ground 13 ticked? Are the facts described actually deterioration, or are they really breach, nuisance or rent facts dressed up as Ground 13?); the 2-week notice period (count the days — a notice served on the 3rd cannot found a claim issued before the 18th); the 12-month window (the claim must be brought within 12 months of the notice); particulars of the deterioration (the notice must give enough detail — "damage to property" by itself is not enough).

On the particulars of claim, check whether each alleged piece of deterioration is properly identified, located, dated and evidenced. A schedule gesturing at "extensive damage throughout the property" without specifics is asking to be struck out, or at least to be put to the landlord at the hearing room by room.

Template letter: request for particulars of the alleged deterioration

Send this within the first 7 days of receiving the Form 6A, by email and recorded delivery.

Dear [Landlord / Agent name],

Re: [Property address] — Section 8 notice dated [date] citing Ground 13

I am writing in connection with the Section 8 notice you served on me on [date] citing Ground 13 of Schedule 2 to the Housing Act 1988. The notice states in general terms that there has been deterioration of the dwelling owing to acts of waste, neglect or default. The notice does not particularise the deterioration alleged.

So that I can respond properly, and so that any court proceedings can proceed on a clear footing, please provide within 14 days the following particulars:

1. A schedule, room by room and surface by surface where relevant, of each item of deterioration relied on, with the location within the property described precisely.

2. For each item of deterioration: the date you say it occurred (or the date you first became aware of it), the act of waste, neglect or default you say caused it, and whether you say the act was committed by me personally or by another person.

3. Where you say deterioration was caused by another person residing in the dwelling, the identity of that person, the dates of their residence at the property, and the steps you say I should have taken for their removal.

4. The estimated cost of remedying each item, with quotes or invoices if you have them.

5. Photographic evidence, dated, of each item of deterioration relied on.

6. A schedule of any prior correspondence in which you raised the deterioration with me before serving the notice, with copies enclosed.

7. The condition of the property at the start of the tenancy, with reference to the inventory and check-in report dated [date if known] which I attach.

I am willing to engage. Where damage is real and is my responsibility I will discuss putting it right. Where it is fair wear and tear, or caused by another party, or in fact attributable to disrepair that you remain obliged to address under sections 11 and 9A of the Landlord and Tenant Act 1985, I will need to defend the claim.

Yours, [Name, date]

Keep a copy. The reply (or absence of one) shapes the case. A landlord who cannot particularise has effectively conceded the discretionary case before the hearing.

Fair wear and tear

Fair wear and tear is the doctrine that quietly defeats a large fraction of Ground 13 claims. The principle is that a tenant is not liable for the deterioration that any property naturally undergoes through normal use over the period of the tenancy. Carpets thin with footfall. Paintwork dulls with sunlight. Hinges loosen. Worktops mark. Skirting boards scuff. None of that is waste, neglect or default — it is the unavoidable consequence of living in a property.

The deposit-scheme adjudication practice (TDS, MyDeposits, DPS) and decades of county court authority converge on a similar approach: a tenant pays for deterioration that goes meaningfully beyond what reasonable use over the tenancy period would produce, taking into account the age of the item, the original condition, the length of the tenancy, the number of occupants, and the use of the room.

In a Ground 13 defence, the argument runs: even if the landlord can establish that some of the items on their schedule are real, the bulk are within the band of fair wear and tear that a multi-year tenancy in this type of property would inevitably produce. A worn carpet in a hallway after four years of family occupation — not a Ground 13 case. A scratch on a kitchen worktop in a six-year tenancy — not a Ground 13 case.

Bring evidence of the property's age, the original condition (inventory and check-in photos), the duration of the tenancy, and the number of occupants. Deposit-scheme adjudication guidance is the easiest framework for a county court judge to apply.

The "another person residing" line

The second limb of Ground 13 — liability for deterioration caused by someone else residing in the dwelling — is fact-specific and often misunderstood. Three things have to come together: the person was residing in the dwelling at the time of the deterioration (visitors do not count); the deterioration was caused by their waste, neglect or default; and the tenant has not taken such steps as they ought reasonably to have taken for the removal of that person.

The reasonable-steps test is the key. For a partner who damaged the property, reasonable steps might include asking them to leave, formally ending the cohabitation, and seeking the landlord's help (or police involvement) if violence or refusal was in play. For a lodger or sub-tenant, it means serving notice to quit and escalating to a court order if necessary. For an adult child, the analysis is mediated by the family relationship — the court understands that family removal is harder than asking a stranger to leave.

A tenant who has visibly engaged with the problem is well placed. A tenant who has done nothing is in a much weaker position. The defence is written around the steps actually taken: every text, every conversation, every formal notice, every letter to the landlord asking for support. Build the chronology.

The reasonableness test

Once the landlord has proved both deterioration and tenant responsibility, the discretionary test asks whether possession is reasonable in all the circumstances. The familiar factors: severity and cost (a small bit of damage that can be put right for a few hundred pounds is rarely a reasonable basis for eviction; a trashed property running into five figures is closer); remediation (has it been remedied, has the tenant offered to pay?); conduct of the landlord (did they raise it before going to law, did they propose a deduction against deposit?); length and stability of the tenancy; impact on the tenant and household (children, vulnerabilities, disabilities, schooling, employment ties).

Two other weightings often decide the case. The fair-wear-and-tear weighting — take that off the top of the schedule and the case shrinks. And the s.11 / s.9A crossover — take landlord disrepair off too and the case shrinks further. See next section.

The s.11 and s.9A crossover

This is where landlords most often trip themselves up. A Ground 13 schedule that lists "mould in bedroom", "damp in bathroom", "rot in window frame" or "broken extractor" is often, in truth, evidence of the landlord's own breach of section 11 (structure, exterior, certain installations) and section 9A (fitness for human habitation — damp, mould, excess cold, ventilation) of the Landlord and Tenant Act 1985.

A landlord cannot rely on damage which is in truth their own disrepair. Mould caused by a leaking external rendering the landlord has not addressed for two years is not Ground 13 deterioration. A window frame rotted because the landlord ignored the tenant's emails is not Ground 13. A carpet ruined by a leak from the flat above is not Ground 13.

The tactic is twofold. First, plead in defence that the items in question are not tenant waste, neglect or default but the landlord's own breach of sections 11 and/or 9A. Second, counterclaim under sections 11 and 9A for damages for the period of unfitness, with a surveyor's HHSRS report as evidence. A counterclaim flips the dynamic. The landlord's possession claim becomes one half of a two-way dispute, and the damages on the counterclaim often dwarf the cost of the alleged Ground 13 remediation. Most landlords settle counterclaimed Ground 13 cases on terms that withdraw the possession claim altogether.

What the court typically does

District judges in the possession list see Ground 13 cases regularly. The common outcomes: where the landlord has produced a credible particularised schedule, photos and prior correspondence, and the tenant has not engaged, the court can make an outright order (14 days, extended to 42 where appropriate). More commonly, where the tenant turns up with a remediation plan and credible evidence on fair wear and tear and landlord disrepair, the court refuses possession or makes a suspended order on terms. Where the landlord has not particularised, the case is adjourned or struck out. Where a counterclaim under s.11 / s.9A is pleaded with a surveyor's report, the case typically settles before trial on terms that the possession claim is withdrawn. A clean outright order on Ground 13 is the worst case, not the standard.

At the hearing — checklist

Bring a tabbed, paginated bundle, three copies (you, landlord, judge): the tenancy agreement; the Form 6A; your particulars-request letter and any reply; the inventory and check-in report from the start of the tenancy; dated photographs of each item the landlord puts in issue; a short witness statement walking through the property room by room with reference to fair wear and tear, third-party causes, and landlord disrepair; witness statements from anyone who can corroborate; quotes for remediation where you accept any items; prior correspondence (particularly emails to the landlord reporting disrepair before the notice); and, if counterclaiming, the surveyor's HHSRS report.

Stand up, speak calmly, take the judge through the schedule room by room, and let the documents do the work.

When to use RentSOS

RentSOS focuses on rent increase challenges under Section 13 rather than possession defence under Section 8 — but the underlying skill is the same: take a procedural document apart line by line and put calmer, better-evidenced facts in front of a decision-maker. If your Ground 13 case is happening against a backdrop of a recent rent increase that has soured the relationship, or a steep rise is signalled, the RentSOS check will tell you whether there are grounds to push back on the rent itself. Landlords who get knocked back on a Section 13 challenge sometimes reach for a Ground 13 notice as a parallel pressure point, and a tenant who has both arguments in hand is in a much stronger position to push the landlord toward sensible engagement.

A calmer last word

A Ground 13 notice can look catastrophic on first read — a list of things "you" have damaged, totted up with replacement values, ending in the threat of eviction. In practice the ground is harder to make out than it looks. Fair wear and tear knocks out a meaningful proportion of the typical schedule. The landlord's own repair obligations knock out more. The "another person residing" line gives breathing room where the damage was caused by someone else and the tenant has visibly engaged with the situation. And the discretionary test means that even on what remains, the judge weighs remediation, conduct, and proportionality before granting possession. Read the schedule carefully, ask for proper particulars, line up your own evidence room by room, and bring a remediation plan if any of it sticks. Go calmly, go prepared, and remember that suspension on workable terms — or outright dismissal — is the usual outcome where the defence is properly built.
