Section 11 Landlord and Tenant Act 1985: London Landlord Repair Obligations (2026)

If you let a residential property in London on anything shorter than a seven-year fixed term, your minimum repair duties are not negotiable. They sit in Section 11 of the Landlord and Tenant Act 1985 — an Act that has survived every housing reform since the Conservative Right to Buy legislation, has been repeatedly upheld by the Court of Appeal, and now sits behind a stack of newer instruments including the Homes (Fitness for Human Habitation) Act 2018 and the Renters' Rights Act 2025 — which extends Awaab's Law to the private sector under its phased commencement roadmap. The five duties Section 11 imposes are the floor below which no London tenancy can lawfully sit.

This guide walks through what each duty actually means in practice on a London letting — which is rarely what landlords expect when they first read the section. We deal with the notice rule, the "reasonable time" question that fills county court lists across Clerkenwell, Wandsworth and Bow, the overlap with selective licensing in 19 London boroughs, and the practical compliance steps that keep you out of the disrepair-claim pipeline.

What Section 11 Actually Covers

Section 11(1) sets out the five covered limbs. The statute is short and the wording matters, so it is worth quoting the substance directly.

The landlord has an implied covenant:

• (a) to keep in repair the structure and exterior of the dwelling-house (including drains, gutters and external pipes);
• (b) to keep in repair and proper working order the installations in the dwelling-house for the supply of water, gas and electricity and for sanitation (including basins, sinks, baths and sanitary conveniences, but not other fixtures, fittings and appliances for making use of the supply of water, gas or electricity);
• (c) to keep in repair and proper working order the installations in the dwelling-house for space heating and heating water.

The Housing Act 1988 inserted Section 11(1A), which extends the structural duty to common parts in flats — so the freeholder of a Camden mansion block or a Hackney converted Victorian terrace cannot leave the stairs, the entrance hall or the roof void in disrepair just because the tenant only rents one flat.

The phrase that does most of the work is "in repair and proper working order". It is not enough that the boiler exists; it must function. It is not enough that the WC exists; it must flush, drain and not leak. Court of Appeal decisions from Quick v Taff-Ely BC [1986] through to Edwards v Kumarasamy [2016] have refined the boundary — particularly on whether design defects count as "disrepair" (they don't, unless the defect causes damage to a covered installation) — but the working test on the ground is whether a reasonable tenant could use the installation for its intended purpose.

What Section 11 Doesn't Cover

Three categories sit outside Section 11 and are worth knowing because they shape what a landlord is and is not on the hook for.

• Tenant's own goods and possessions. A leaking radiator that ruins a tenant's sofa is the landlord's repair responsibility, but the sofa damage is a separate claim under contents insurance — Section 11 doesn't compensate for it, although it can be claimed as consequential loss in a Section 11 damages action.
• Cosmetic decoration and finishes. Tired carpets, scuffed paintwork, dated kitchen worktops — these are not "disrepair" unless they reach a point of damage that affects use. The threshold is much higher than tenants often expect.
• Damage caused by the tenant. Warren v Keen [1953] establishes the implied tenant-like-user duty. A tenant who breaks a window in anger, blocks a drain with cooking fat, or pulls a basin off the wall has caused the damage themselves and the landlord can charge for the repair, typically against the deposit at end of tenancy.

The grey area — the one that fills disrepair listings — is mould and condensation. The landlord can argue it is caused by tenant lifestyle (drying laundry indoors, blocked vents); the tenant can argue it is caused by failed extract fans, single-glazed windows, or a leaking roof. Awaab Ishak's death in Rochdale in 2020, and the Awaab's Law that followed, has pushed the legal threshold firmly toward landlord responsibility for any mould in a habitable room that has not been remediated within the statutory timescale.

The Notice Requirement

A Section 11 obligation only becomes enforceable once the landlord has notice of the defect — knowledge that the repair is needed. This is the rule from O'Brien v Robinson [1973] and it still holds. The notice does not have to be written, but in any subsequent dispute the tenant carries the burden of proving the landlord knew, so written notice is what every London tenant should be advised to use.

Practical points on notice that come up in our work every week:

• An email to the landlord or the managing agent is good notice — provided it describes the defect, the date, and the location.
• A phone call counts, but only if the tenant can produce a contemporaneous note or text confirming what was said.
• A complaint to a neighbour or a passing builder does not count.
• For exterior or common-part defects, the landlord is treated as having notice if the defect would have been spotted on a reasonable inspection — the rule from Edwards v Kumarasamy [2016].
• Gas leaks, water leaks visible from the street, and roof defects visible from the pavement can all give "constructive notice" even without the tenant calling.

What Counts as a 'Reasonable Time'

Section 11 doesn't put a number on the response window. The Act says the duty is to repair "within a reasonable time of being notified". County court practice has gradually filled this in. The working London expectations in 2026 are:

• Total loss of water supply: 24 hours, or same-day in heat-wave conditions.
• Total loss of heating between October and April: 24-48 hours, faster for properties with very young children, elderly, or disabled occupants.
• Total loss of hot water: 48-72 hours.
• Suspected gas leak: 24 hours under Section 11, but also subject to the immediate-response duty under GSIUR 1998 — the gas supply must be made safe within 4 hours of report under standard supplier protocols.
• Major water leak inside the property: 24-48 hours to make safe, longer to fully repair if the source is structural.
• WC inoperative (single bathroom property): 24-48 hours.
• Partial heating failure (one radiator, mild weather): 7-14 days.
• Non-urgent structural items: up to 28 days, sometimes longer if scaffolding or planning approval is needed.

These are not statutory limits — they are county court expectations. A judge sitting at Wandsworth, Central London or Bow county court will measure what the landlord did against these working norms, and against the specifics of the case (age of property, vulnerability of tenant, weather, contractor availability).

Homes (Fitness for Human Habitation) Act 2018

The 2018 Act amended the Landlord and Tenant Act 1985 to insert Sections 9A to 9C, imposing a separate duty on every residential landlord to ensure the dwelling is "fit for human habitation" at the start of the tenancy and throughout it. The fitness duty overlaps with Section 11 but goes further — it covers items Section 11 doesn't reach, such as natural lighting, ventilation, freedom from damp, and absence of HHSRS Category 1 hazards.

Critically, the 2018 Act gave the tenant a direct right of action — they no longer have to rely on the local council's environmental health team to enforce. A tenant in a Croydon flat with persistent mould, or a Westminster basement with inadequate ventilation, can issue a county court claim directly against the landlord under Section 9A.

Awaab's Law — Phase 3 of the Renters' Rights Act 2025

Awaab's Law, named after the two-year-old Rochdale boy who died from prolonged exposure to mould in a social housing flat, was originally written for the social rented sector under the Social Housing (Regulation) Act 2023 and commenced for social landlords on 27 October 2025. The Renters' Rights Act 2025 then extends equivalent provisions to the private rented sector — but as Phase 3 of the government's implementation roadmap, with the precise commencement date set by future MHCLG regulations (not yet laid as of May 2026). Section 21 abolition and the conversion to periodic tenancies, by comparison, took effect on 1 May 2026 in Phase 1.

When the PRS regulations commence, the Law will fix strict response timescales for hazards by category:

• "Emergency" hazards (immediate risk to life or health — gas leak, electrical hazard, severe water ingress): make safe within 24 hours.
• "Significant" hazards (HHSRS Category 1 and severe Category 2 — mould, damp, excess cold, asbestos, falls): begin investigation within 14 calendar days, complete works within a "reasonable" timescale defined in the underlying code of practice.
• Recording duty: landlords must keep written records of hazard reports and the response timeline, retained for at least seven years.

For London landlords, the practical implication is that the loose "reasonable time" test of Section 11 case-law is being overlaid with hard numbers for the worst categories of disrepair. The disrepair claim pipeline — which has already grown into a substantial London county court caseload — will absorb Awaab's Law breaches as separate causes of action.

London-Specific: Selective Licensing Overlap

Nineteen of the 32 London boroughs operate selective licensing or additional licensing schemes in 2026, including Newham (borough-wide since 2013, renewed three times), Croydon, Waltham Forest, Tower Hamlets, Brent, Hackney, Haringey, Enfield, Barking and Dagenham, Redbridge, Southwark, Lewisham, Greenwich, and parts of Westminster, Camden, Islington and Lambeth on rolling sub-area designations. Each scheme imposes licence conditions on top of Section 11 — typically including:

• Annual gas safety checks (already a separate duty under GSIUR 1998).
• EICR every five years for the electrical installation.
• Maintenance of working smoke alarms on every storey and CO detectors in rooms with solid-fuel appliances.
• Compliance with the borough's specific property standards — which often go beyond the HHSRS minimum.
• Annual or two-yearly internal inspection by the landlord or their managing agent.

Breach of a licence condition is a separate offence from breach of Section 11 — the borough can prosecute or issue a civil penalty up to £30,000 under the Housing and Planning Act 2016. The two regimes run in parallel: a landlord can be sued by the tenant under Section 11 and fined by the borough under the licensing regime for the same underlying disrepair.

Gas, Electricity and the Compliance Stack

Section 11(b) covers the installations for gas and electricity, but these are also separately regulated:

• Gas Safety (Installation and Use) Regulations 1998: annual landlord gas safety certificate (CP12) covering every gas appliance and flue, issued by a Gas Safe registered engineer. The certificate must be given to existing tenants within 28 days, and to new tenants before they move in. Failure is a criminal offence.
• Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020: EICR every five years (or sooner if the report specifies), valid for all private tenancies since 1 April 2021.
• Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022: at least one smoke alarm on every storey with a room used as living accommodation, and a CO alarm in any room with a fixed solid-fuel or gas combustion appliance (except gas cookers, since the 2022 amendment widened the duty).

A landlord facing a Section 11 disrepair claim involving gas or electricity will almost always also be questioned on the corresponding compliance certificate. If the boiler failed and there is no current CP12, the breach widens beyond Section 11 into criminal regulatory territory.

Damages and Enforcement

If the matter reaches the county court, the standard remedies are:

• Specific performance: a court order requiring the landlord to do the repair within a stated timeframe, on pain of contempt.
• General damages for inconvenience and distress: typically £1,500-£5,000 per year of significant disrepair, sometimes more for serious cases. Wallace v Manchester CC [1998] remains the framework.
• Special damages: proven out-of-pocket losses — extra heating costs from a broken boiler, alternative accommodation, ruined possessions.
• Diminution in value of the tenancy: assessed as a percentage of the rent for the period of disrepair. Recent London awards have ranged from 10% (minor disrepair affecting one room) to 50% (severe damp and heating failure for a sustained period).
• Set-off: in egregious cases where the landlord refuses to act, the court can authorise the tenant to carry out the work and deduct the cost from future rent.

The litigation route is governed by the Pre-Action Protocol for Housing Conditions Claims in England. The tenant sends a Letter of Claim, the landlord has 20 working days to respond, then experts and disclosure follow. Most cases settle before trial — often with the landlord paying damages plus the tenant's reasonable costs under the qualified-one-way costs-shifting regime.

Practical Compliance Checklist for London Landlords

The single best protection against a Section 11 claim is a documented inspection and response routine. The checklist we recommend to the landlords we work with:

1. Inspect at lease grant and at least every six months thereafter, with photos and a written log retained for the duration of the tenancy plus seven years (the Awaab's Law retention period).
2. Acknowledge every repair report in writing within 24 hours, stating the planned response time and contractor. This single step kills most disrepair claims at notice stage.
3. Use Gas Safe and NICEIC-registered contractors, retain the certificate or invoice on every job, and pass copies to the tenant where statute requires.
4. Maintain a 24/7 emergency contact — a managing agent's out-of-hours line, or a contracted emergency plumbing service. The "reasonable time" test gets much harsher when a tenant can't reach the landlord at all.
5. Run a CP12 every 12 months and an EICR every 5 years as a minimum baseline — these are statutory regardless of property condition.
6. Treat any mould or damp report as Awaab's Law-grade from now — investigate within 14 days, document the outcome — even though the PRS commencement date is yet to be set. Boroughs are already enforcing under HHSRS and the Fitness for Habitation Act on the same standard.
7. For HMOs and selective licensing properties, read the licence conditions annually and check them against your records — many breaches are unintentional.
8. Carry buildings and contents insurance with property-owner liability, minimum £2 million PL cover, plus emergency assistance for tenants if your portfolio is dispersed across multiple London boroughs.

Section 11 is one of the older pieces of English landlord-and-tenant legislation, but it remains the spine of every disrepair claim in 2026. The accretion of newer instruments — the 2018 Fitness Act, the 2020 Electrical Regulations, the 2022 Alarm Regulations, the Renters' Rights Act 2025 phased commencement, and the pending Awaab's Law extension to the PRS — keeps adding compliance layers on top, but the fundamental duty to keep the structure, the services and the heating in working order has not changed in 41 years. London tenants and London judges know the standard. Run a property to the checklist above and the standard is met.
