Equality Act 2010 s.15: the disability discrimination defence to possession (tenant walkthrough, 2026)

For a disabled tenant facing possession, the most powerful defence is often the one that is not in the Housing Act 1988 at all. Section 15 of the Equality Act 2010 sits in a different statute and applies in employment, services and education as much as housing. But in a possession claim it does something the housing-law grounds cannot: it forces the landlord to justify, in front of the judge, that evicting this particular tenant — with their particular disability and their particular circumstances — is a proportionate response to a legitimate aim. The landlord can prove every element of Ground 8, Ground 12 or Ground 14 and still lose, if proportionality breaks down.

This walkthrough is for a disabled tenant who has received a Section 8 notice or possession claim and believes the conduct cited is linked, even partly, to their disability. It covers what section 15 actually says, how it overlays onto every Section 8 ground (Akerman-Livingstone), the proportionate-means-of-a-legitimate-aim test, the narrow knowledge defence, the reasonable adjustments duty in section 20, the evidence that wins these cases, and the suspended-order route that many disabled tenants end up on. There is a paragraph at the end you can paste straight into your N11 defence form — that paragraph, properly evidenced, is the difference between a defence that gets heard and one that gets brushed past.

What section 15 actually says

Section 15(1) of the Equality Act 2010 reads, in plain English: a person discriminates against a disabled person if (a) they treat the disabled person unfavourably because of something arising in consequence of the disabled person's disability, and (b) they cannot show that the treatment is a proportionate means of achieving a legitimate aim.

Read that twice. The unlawful treatment is not "treating someone unfavourably because of disability" — that would be direct discrimination under section 13. Section 15 is broader. It captures treatment because of something arising from the disability. The landlord does not have to be motivated by the disability itself. They only need to be acting on conduct or circumstances that, in fact, flow from it.

In housing this is enormous. A tenant whose mental health crisis caused them to miss a benefit assessment, whose Universal Credit stopped, whose rent then went into arrears — that is unfavourable treatment (eviction) because of something (arrears) arising in consequence of disability. A tenant with autism whose sensory regulation manifests as noise complaints — eviction for nuisance is treatment because of something arising in consequence of disability. A tenant with chronic fatigue who missed three access appointments for the gas safety check — eviction for breach is treatment because of something arising in consequence of disability.

Section 15(2) gives the landlord a defence if they did not know, and could not reasonably have been expected to know, that the tenant was disabled. That knowledge defence is narrower than landlords often think — more below.

Why it works against every Section 8 ground (Akerman-Livingstone)

For a long time there was uncertainty about whether the Equality Act defence could really bite against the mandatory possession grounds. Ground 8 in particular — two months of arrears, no judicial discretion, order made — looked like a wall the defence could not get over.

In Akerman-Livingstone v Aster Communities Ltd [2015] UKSC 15 the Supreme Court closed that argument. The court held that the Equality Act defence is a substantive defence that runs alongside any housing-law ground and must be considered separately and properly. The court cannot simply note that the ground is mandatory and bypass the proportionality analysis. Even where the ground itself leaves no discretion, the disability discrimination question is a separate question, and the landlord has to clear it.

The practical effect is that a disabled tenant on Ground 8 arrears is not in the desperate position the statute might suggest. The arrears can be proved, the threshold can be met, and the tenant can still win — or at minimum negotiate a suspended order — if the arrears arise from disability and eviction is not proportionate. The same applies to Grounds 7A, 7B and the other Schedule 2 Part 1 mandatory grounds. The Renters' Rights Act 2025 did not alter this; if anything, the abolition of Section 21 has pushed more disability cases into the Section 8 stream where section 15 is available.

The proportionate means of a legitimate aim test

This is where most section 15 defences are actually decided. Once the tenant has shown that the treatment is because of something arising in consequence of disability — and the landlord has not made out the knowledge defence — the landlord carries the burden of proving that eviction is a proportionate means of achieving a legitimate aim.

The legitimate aim is rarely the problem. Recovery of arrears, protection of other residents, prudent management of social housing stock, enforcement of tenancy terms — courts accept these as legitimate. The fight is on proportionality, which has four practical limbs:

Appropriateness. Is eviction actually a sensible way to achieve the aim? If the tenant is on a Debt Relief Order or a managed payment plan that is working, eviction does not recover the arrears any faster — it just makes the tenant homeless.

Necessity. Is there a less intrusive measure available? A suspended order on terms, a rent repayment plan, a referral to a money advice or mental health service, a switch to direct payment of the housing element — all can achieve the legitimate aim with less impact.

Real-world impact on this tenant. Loss of secure housing for someone with a stabilising mental health condition can be catastrophic. Loss of an adapted property for a tenant with mobility needs may make rehousing all but impossible. The local authority's homelessness duty does not normally produce the same property within reach of the same support network.

Balance. The court weighs the landlord's aim against the tenant's impact. The more drastic the impact and the more practical the alternative, the less proportionate eviction looks.

A proportionality analysis on paper is not enough. The tenant has to put the alternatives in front of the court — a payment plan they have already opened, a support worker's letter, an OT report on the property's adaptations, a willingness to engage with a structured remedy. Proportionality is not theory. It is the practical question of whether the judge can see a workable alternative to eviction.

The knowledge defence — and why it usually fails

Section 15(2) says nothing in section 15(1) applies if the landlord shows that they did not know, and could not reasonably have been expected to know, that the tenant had the disability. Both limbs have to be satisfied. The second is what catches landlords out.

A landlord is reasonably expected to know if the tenancy application disclosed a disability or health condition; a medical letter, OT report or social services correspondence has been sent to the landlord or letting agent; a support worker, family member or local authority has been in touch on the tenant's behalf in a way that signalled disability; or the tenant's behaviour during the tenancy has displayed obvious indicators that would put a reasonable landlord on enquiry — repeated benefit-linked arrears, communications suggesting cognitive difficulty, visible mobility aids, missed appointments with consistent health-linked explanations.

Once any of those triggers have happened, the landlord cannot later claim ignorance. The defence is also defeated by knowledge held by the landlord's agent — the letting agent's knowledge is the landlord's knowledge. Where the disability is genuinely hidden and never disclosed, the section 15 route is harder, but a tenant may still have a section 19 indirect discrimination argument.

Section 20 — the reasonable adjustments duty

Section 20 sits alongside section 15 and is often the practical lever. The duty is to make reasonable adjustments where a provision, criterion or practice puts a disabled tenant at a substantial disadvantage compared to a non-disabled tenant.

In a possession context, reasonable adjustments commonly look like accepting rent by methods that suit the tenant's circumstances (direct from Universal Credit, weekly instead of monthly), giving extra time to respond to notices where cognitive or mental health issues make rapid engagement impossible, providing notices in accessible formats, coordinating with support services or family members where direct engagement is impractical, adjusting inspection regimes around the tenant's energy levels, and holding back from formal enforcement while a referral to mental health crisis services or debt advice is being worked through.

A landlord who has refused or ignored obvious adjustments is on weak proportionality ground. The two defences feed each other: the failure to adjust is both a freestanding unlawful act and feeds the argument that eviction is not a proportionate means of a legitimate aim because less intrusive measures were available and were declined.

Evidence — what to put in the bundle

A section 15 defence is only as strong as its evidence. The bundle should contain:

Medical evidence. GP letters, hospital correspondence, mental health team letters, OT reports. A short GP letter confirming the diagnosis, that it is long-term, and that it has a substantial impact on day-to-day life does a lot of heavy lifting on the Equality Act definition.

Benefit evidence. PIP, ESA, Universal Credit limited capability for work, DLA award letters establish disability for these purposes without further argument in most cases.

Disability impact statement. A short, plain-English statement, in your own words, describing how the condition affects daily life and how the conduct cited in the possession claim arises from it. Three pages is plenty. This is the document judges actually read carefully.

Support correspondence. Letters from support workers, mental health teams, social services — anyone who has been involved in your care or housing.

Engagement evidence. Proof that you have tried to engage with the issue — emails to the landlord, payment plans set up, referrals made. The "tried-but-struggled" picture is much stronger than silence.

Alternative plan. A practical, costed, evidenced alternative to eviction — a payment plan with figures, a support plan with start dates, an undertaking that addresses the conduct.

Tab the bundle, paginate it, and bring three copies. Lead with the impact statement.

Template paragraph: pleading an Equality Act s.15 defence to a Section 8 claim

Paste this into the relevant section of your N11 defence form (the form for defendants in a possession claim), adjusting the details. It is a starter — a housing solicitor or Shelter adviser can sharpen it.

The defendant is a disabled person within the meaning of section 6 of the Equality Act 2010. The defendant has [name the condition — e.g. a long-term mental health condition diagnosed as recurrent depressive disorder] which has a substantial and long-term adverse effect on her ability to carry out normal day-to-day activities. Evidence of disability is at pages [x–y] of the defendant's bundle.

The conduct relied on by the claimant in support of Ground [8 / 12 / 14] arises in consequence of the defendant's disability. In particular, [briefly describe the link — e.g. the rent arrears arose because the defendant's mental health deteriorated in [month/year], she was unable to attend a Universal Credit work capability assessment, her UC payments were suspended for [period], and the resulting shortfall accumulated as arrears]. Possession is therefore unfavourable treatment because of something arising in consequence of disability, within section 15(1)(a) of the Equality Act 2010.

The claimant knew, or could reasonably have been expected to know, that the defendant was disabled. The defendant relies on [list the trigger events — e.g. the disability disclosure on the tenancy application dated [date], the letter from the defendant's GP dated [date] sent to the claimant's letting agent, the involvement of [support worker / social worker / family member] in correspondence with the claimant from [date]].

The claimant has not shown, and cannot show, that possession is a proportionate means of achieving a legitimate aim. Less intrusive measures are available, including [list — e.g. a suspended possession order on terms of a payment plan of £[x] per month over [period], direct payment of the housing element of Universal Credit, engagement with [named support service], and reasonable adjustments to the rent payment regime]. The claimant has failed to make reasonable adjustments under section 20 of the Equality Act 2010, in particular [briefly describe]. The defendant therefore relies on sections 15 and 20 of the Equality Act 2010 as a substantive defence to the claim, and in the alternative seeks a suspended order on terms.

Send a copy of the filed N11 and bundle to the claimant in accordance with the directions in the claim. Ask the court for a longer hearing slot if the proportionality analysis cannot reasonably be done in the standard 10-15 minute possession list — many courts will list these as 30-minute or even half-day hearings when properly flagged.

The suspended order route

Most disability discrimination defences that succeed in the possession list end not with the claim being dismissed but with a suspended possession order on terms. A suspended order means the landlord gets a possession order but it does not take effect unless the tenant breaches the terms — typically, terms requiring continued rent payment plus a small amount off the arrears each month.

That outcome is, in most cases, a win. It keeps the tenant in their home, regularises the arrears, and gives the landlord the comfort of an order on the file. The court is much more willing to grant a suspended order where the Equality Act defence has been engaged seriously, because the suspended order is the proportionate alternative the section 15 analysis points to.

In the N11 and at the hearing, plead the section 15 defence as a full defence, but plead in the alternative that any order should be suspended on terms you can realistically meet. Spell out the terms — figures and dates — so the judge has a workable order to make. A judge with a credible suspended-order proposal in front of them is much less likely to make an outright order.

When to use RentSOS

RentSOS focuses on rent increase challenges under Section 13, not on possession defence under Section 8 — but the underlying mechanic is the same: take a one-sided procedural document apart, put calmer evidenced facts in front of a decision-maker, and ask for a proportionate outcome. If your Equality Act defence is happening against a backdrop of a recent rent rise that pushed the affordability over the edge, or if a steep rise is signalled and the relationship is already strained, the RentSOS check will tell you whether there are grounds to challenge the rent itself. Knocking the increase back is sometimes the cleanest way to make the underlying arrears problem solvable, which in turn makes the proportionality argument easier for the judge to accept.

A calmer last word

A possession claim is frightening, and disability makes the prospect of moving harder still. Section 15 is one of the strongest protective tools in the statute book, and Akerman-Livingstone confirmed that it cannot be bypassed by reaching for a mandatory ground. The defence does not run itself — it has to be pleaded, evidenced, and argued. Build the impact statement, gather the medical letters, set out a realistic alternative, and put the bundle in front of the judge. The court is required to consider proportionality properly. Go calmly, go prepared, and remember that a suspended order on workable terms is, in this corner of housing law, a successful outcome.
