Housing Act 2004: A Landlord's Guide

What changed in 2026

The HHSRS was overhauled from 23 June 2026 — fewer, simpler hazard categories and a new High/Medium/Low banding system. Civil penalties for housing offences rose from £30,000 to £40,000 from 1 May 2026, and a new £7,000-per-hazard penalty now applies directly to Category 1 hazards. A Decent Homes Standard is coming to the private rented sector for the first time — but not until 2035. Read the Renters' Rights Act 2025 hub.

The Housing Act 2004 is one of the two foundational statutes governing the private rented sector in England, alongside the Housing Act 1988. Where the 1988 Act (as rewritten by the Renters' Rights Act 2025) governs the tenancy itself, the 2004 Act regulates the property: the standard it must meet, the licensing of HMOs and other categories of rented housing, the protection of tenancy deposits, and the enforcement powers local authorities use to act on all of it.

At a glance

• Who this is for: private landlords and letting agents in England managing tenancies, HMOs, or licensed properties.
• Governing law: Housing Act 2004 (Parts 1, 2, 3, 6 and 7), as substantially amended by the Housing and Planning Act 2016 and the Renters' Rights Act 2025.
• Key figures: civil penalties up to £40,000 per offence (or £7,000 for certain breaches and Category 1 hazards); deposit non-protection penalty of 1–3× the deposit; rent repayment orders up to 24 months' rent (correct as at July 2026).
• What's new for 2026: the HHSRS hazard and banding overhaul (23 June 2026), the £40,000 civil penalty cap (1 May 2026), the section 6A Category 1 hazard penalty, and confirmation that a Decent Homes Standard is coming to the PRS from 2035.

Part 1 — Housing conditions and the HHSRS

Part 1 of the Act introduced the Housing Health and Safety Rating System (HHSRS) — the hazard-based assessment local authorities use to evaluate housing standards and decide whether to take enforcement action.

Local authority environmental health officers assess a property against a set of prescribed hazards — categories including damp and mould, excess cold, fire safety, falls, sanitation, and electrical safety. Each hazard identified is scored, and the local authority's duties then depend on how serious it is:

• Category 1 hazards (the most serious): the local authority has a duty to take enforcement action — typically an improvement notice, a hazard awareness notice, a prohibition order, or (in extreme cases) emergency remedial action.
• Category 2 hazards: the local authority has a discretion to act, but is not required to.

The 2026 HHSRS overhaul. Following a multi-year review, the Housing Health and Safety Rating System (England) (Amendment) Regulations 2026 (SI 2026/571) came into force on 23 June 2026, applying to inspections started on or after 22 June 2026 (older inspections already underway are assessed under the previous system). The reform:

• Reduces the number of prescribed hazards from 29 to 21, by combining hazards with similar causes and outcomes — for example, merging Fire with Explosions, and combining several damp, hygiene and pest-related hazards.
• Replaces the old lettered A–J hazard bands with three plain-language bands: High (broadly replacing Category 1), and Medium and Low (both within Category 2).
• Renames the four harm classes from Class I–IV to Extreme, Severe, Serious and Moderate.
• Introduces published "indicative baselines" — plain-language checklists (for example, "stairs must be safe, secure, in sound condition, free of defects and projections, well maintained") to help landlords and tenants understand what a compliant property looks like, without replacing the full risk assessment.

The reform changes how hazards are labelled, scored and banded — it does not lower the minimum standard a property must meet. A property that would previously have generated a Category 1 finding should still generate a High-band finding under the new system.

Enforcement for Category 1/High hazards got sharper in 2026 too. A new section 6A of the Housing Act 2004, inserted by the Renters' Rights Act 2025, gives local authorities a direct civil penalty power — up to £7,000 per hazard — where a landlord fails to take reasonably practicable steps to keep a property free of a Category 1 (High) hazard. This is a standalone penalty route alongside the existing improvement notice and prosecution powers, and commenced alongside the wider HHSRS reform.

Part 2 — Mandatory HMO licensing

Part 2 of the Act creates the mandatory HMO licensing regime. The principal provisions:

• Section 55: requires a licence for every HMO meeting the prescribed description.
• Section 254: defines what constitutes an HMO — broadly, three or more occupiers from two or more households, sharing an amenity.
• Section 257: covers a narrower category of converted blocks of flats.
• Section 258: sets the test for when occupiers are treated as not forming a single household — the test that often determines whether a particular property is an HMO. (Section 263 separately defines the "person having control" and the "person managing" a property.)

The scope of mandatory licensing — HMOs occupied by 5 or more people from 2 or more households — was set by the Licensing of Houses in Multiple Occupation (Prescribed Description) (England) Order 2018, which removed the previous three-storeys-or-more qualifying condition and substantially expanded the licensable population. This threshold has not changed in 2026.

See our HMO licensing guide for the practical detail: how to apply, the fit-and-proper-person test, and the civil penalty exposure for non-compliance (below).

Part 3 — Selective licensing

Part 3 lets a local authority impose licensing on private rented properties that are not HMOs. Selective licensing schemes are designated by the local authority, typically on grounds such as low housing demand, significant anti-social behaviour, poor property condition, or high levels of deprivation or crime, following consultation.

Schemes typically run for up to 5 years and can cover specific streets, wards, or larger areas. The number of local authorities operating selective licensing has grown steadily since 2010 and continues to expand. Because schemes and their boundaries are set independently by each council, always check the current position with the specific local authority — via its website or the GOV.UK selective licensing guidance — before letting a property in any area where the position is unclear. Operating without a required selective licence is a housing offence carrying civil penalty exposure (see below).

Part 6 — Tenancy deposit protection

Part 6 introduced statutory tenancy deposit protection. Sections 212–215 require:

• Deposits taken on an assured tenancy (assured shorthold tenancies were replaced by assured periodic tenancies for most private lettings from 1 May 2026 under the Renters' Rights Act 2025) to be protected in a government-authorised scheme within 30 days of receipt.
• Prescribed information about the deposit and its protection to be given to the tenant within the same 30-day window.
• The deposit to be returned — or any disputed sum referred to scheme adjudication — at the end of the tenancy.

Penalties for failure remain severe. Under section 214, a court can order a landlord who fails to comply to pay the tenant between 1 and 3 times the deposit as a penalty, on top of returning the deposit itself. This is unaffected by any other changes to the Act.

Historically, non-protection also barred a landlord from serving a valid Section 21 notice. That consequence is now historical: Section 21 was abolished by the Renters' Rights Act 2025 with effect from 1 May 2026, so there is no longer a Section 21 route to lose. The section 214 financial penalty, however, applies exactly as before, and non-protection can also affect a landlord's ability to rely on certain Section 8 grounds.

See our deposit protection guide for the operational detail.

Part 7 — Powers and duties

Part 7 sets out local authorities' inspection and enforcement powers:

• Right of entry for environmental health officers to inspect residential property where they have reasonable grounds to suspect a breach.
• Notice requirements before entry — typically 24 hours except in emergencies.
• Powers to require information from landlords, agents and others about how a property is operated. The Renters' Rights Act 2025 significantly extended these investigatory powers from 27 December 2025, giving councils stronger rights to demand documents and access third-party data.
• Powers to remediate at the landlord's expense where the landlord fails to comply with an improvement notice or other enforcement action.

Civil penalties: the £40,000 (and £7,000) regime

The Housing and Planning Act 2016 first introduced civil penalties as an alternative to criminal prosecution for housing offences. The Renters' Rights Act 2025 substantially expanded and restructured this regime from 1 May 2026.

There are now two tiers:

Tier	Maximum	Examples	Prosecution alternative?
Breach	£7,000	Category 1/High hazard non-compliance (s.6A); certain assured tenancy and rental-bidding breaches	No — civil penalty only
Offence	£40,000 (up from £30,000 from 1 May 2026)	Unlicensed HMO or selective-licensing property; breach of an improvement notice; breach of HMO management regulations; overcrowding notice breach	Yes — local authority can prosecute instead

Local housing authorities set their own civil penalty policies, but GOV.UK's statutory guidance gives illustrative national starting points for individual Housing Act 2004 offences, including: failure to comply with an improvement notice, £25,000; an unlicensed mandatory or additional HMO, £17,000 each; knowingly permitting HMO over-occupation, £20,000; an unlicensed property subject to selective licensing, £12,000; breach of an overcrowding notice, £20,000; and breaches of HMO management regulations ranging from £3,000 to £20,000 depending on the specific failure. These are starting points, not caps — local authorities can and do go up to the £40,000 statutory maximum depending on severity, culpability, harm caused, and the landlord's compliance history.

Civil penalties:

• Are imposed by the local authority as an alternative to prosecution (for "offence"-tier breaches).
• Are appealable to the First-tier Tribunal (Property Chamber) within 28 days.
• Use a "beyond reasonable doubt" standard for most Housing Act 2004 offences, since prosecution remains available as an alternative.
• Can be issued multiple times for separate offences, and again for a continuing or repeat breach.

Rent Repayment Orders

Sections 73–75 of the Act, as amended by the Housing and Planning Act 2016 and further extended by the Renters' Rights Act 2025, let tenants and local authorities apply to the First-tier Tribunal for an order requiring a landlord to repay rent received during a period of housing offences — most commonly operating an unlicensed HMO.

Key changes from 1 May 2026:

• The maximum claimable doubled from 12 to 24 months' rent.
• The application time limit also doubled, from 12 to 24 months after the offence.
• Rent repayment orders were extended to superior landlords and company directors, closing a gap that let rent-to-rent operators shield individuals from liability.
• A landlord with a prior conviction, financial penalty, or rent repayment order for the same type of offence must now be ordered to pay the maximum amount — the Tribunal's discretion is removed for repeat offenders.

Rent repayment orders can be combined with a civil penalty for the same underlying conduct — a landlord can face both a civil penalty of up to £40,000 and a rent repayment order of up to 24 months' rent from the same unlicensed HMO. See our full rent repayment orders guide for the tribunal process and how to defend a claim.

Banning Orders and the Database of Rogue Landlords

Powers introduced by the Housing and Planning Act 2016 let the First-tier Tribunal make Banning Orders against landlords convicted of certain offences. A banning order:

• Bans the landlord from letting activities for at least 12 months.
• Can target specific activities (managing, letting, advertising) or all letting-related activity.
• Is enforceable nationally — a banning order made in one local authority area applies across England.

Landlords subject to banning orders are also entered on the Database of Rogue Landlords and Property Agents, accessible to local authorities nationally.

Where the Act is heading: Decent Homes Standard and Awaab's Law

Two further reforms are coming to the private rented sector, but neither is in force yet as at July 2026:

• Decent Homes Standard. Following its consultation, the government confirmed on 28 January 2026 that a Decent Homes Standard will apply to privately rented homes for the first time — but not until 2035. It will sit alongside, not replace, the HHSRS.
• Awaab's Law. Already in force for social housing, Awaab's Law sets fixed legal timeframes for landlords to investigate and fix serious hazards. The government has confirmed it will extend Awaab's Law to the private rented sector, but as at July 2026 no implementation date has been set and the details remain subject to consultation.

Landlords should not treat either as a current legal requirement, but both are a clear signal of direction — investing in HHSRS compliance now reduces future retrofit risk.

Practical compliance checklist

• Know your HMO status. Count occupiers and households against the section 254 test; if you're at or near 5 occupiers/2 households, check licensing requirements before you let.
• Check selective licensing locally. Requirements vary street by street in some areas — confirm directly with the local authority, don't assume.
• Protect every deposit within 30 days and serve the prescribed information at the same time — the section 214 penalty is strict and the court has limited discretion to excuse late protection.
• Treat Category 1/High HHSRS hazards as urgent. The section 6A penalty and improvement notice route both apply, and Awaab's Law-style timeframes are the direction of travel even before they're mandatory for the PRS.
• Keep records of remedial work and inspections — evidence of proactive maintenance is the strongest defence against both civil penalties and rent repayment orders.
