The Decent Homes Standard for Private Landlords

For most of its history, the Decent Homes Standard applied only to social housing. The Renters' Rights Act 2025 changes that. For the first time, private landlords will be required to meet a minimum standard that goes beyond simply not having dangerous hazards — a standard that covers the physical condition of the property, the age and adequacy of its facilities, and whether tenants can keep warm.

This guide explains what the Decent Homes Standard requires, when it will apply to your properties, and what you should be doing now to prepare.

What Is the Decent Homes Standard?

The Decent Homes Standard is a set of four criteria that a property must meet in order to be considered acceptable for habitation. It was introduced in 2000 and has been used in the social rented sector ever since as a benchmark for housing quality. The Renters' Rights Act 2025 extends it to private rented sector properties for the first time, under Section 100.

The four criteria are:

1. Freedom from Serious Hazards (HHSRS Category 1)

A decent home must be free from hazards assessed as Category 1 under the Housing Health and Safety Rating System (HHSRS). Category 1 hazards are those that pose a serious and immediate risk to the health or safety of occupants — things like severe damp and mould, dangerous electrical installations, excess cold, structural collapse risks, or falls on stairs.

The HHSRS is already the framework councils use when inspecting private rented properties. This criterion effectively makes it a legal standard rather than merely an enforcement trigger.

2. Reasonable State of Repair

The property must be in a reasonable state of repair. This covers the structure and exterior of the building — roof, walls, windows, and doors — as well as internal fixtures and fittings. A property is not in reasonable repair if it has structural defects, persistently failing systems, or deterioration that is the result of the landlord's failure to maintain.

This criterion overlaps with the existing repairing obligation under Section 11 of the Landlord and Tenant Act 1985, but the Decent Homes framing is broader. It is about the overall condition of the property, not just specific defined elements.

3. Reasonably Modern Facilities and Services

The property must have facilities and services that are reasonably modern. The guidance considers whether key elements such as the kitchen, bathroom, and heating system are sufficiently up to date. A kitchen over 30 years old without significant updating, or a bathroom over 40 years old, is likely to fail this criterion.

This does not mean landlords must install brand-new kitchens on a fixed schedule. The test is whether the facilities are adequate and functional. Worn but working is likely to be acceptable; structurally inadequate or visibly dilapidated is not.

4. Reasonable Degree of Thermal Comfort

The property must offer a reasonable degree of thermal comfort. This means it must have both an efficient heating system and effective insulation. A property that cannot be adequately heated, or where heat loss is so severe that heating bills are prohibitive, fails this criterion.

This criterion connects directly to the Energy Performance Certificate (EPC) regime. A property rated F or G is almost certainly going to fail the thermal comfort test.

The HHSRS: How It Works

The Housing Health and Safety Rating System is the legal framework used to assess hazards in residential properties. It covers 29 categories of hazard — from damp and cold to fire, falls, and electrical risks.

Each hazard is scored based on:

• The likelihood of an occurrence that could cause harm
• The severity of the likely harm if an occurrence did take place

Hazards that score above a threshold are classed as Category 1 (serious and immediate risk) or Category 2 (significant but not immediately serious). Local councils have a duty to take enforcement action on Category 1 hazards and a power to act on Category 2.

Under the Decent Homes Standard extension to the private sector, freedom from Category 1 hazards is a baseline legal requirement — not something a landlord can address after a council inspection, but something they must ensure before it ever gets that far.

Timeline: When Does This Apply?

The Renters' Rights Act 2025 has passed, but the practical implementation of the Decent Homes Standard in the private rented sector is not immediate.

Current position: The standard is not yet in force for private landlords.

Proposed timeline: The government has indicated a target implementation window of 2035 to 2037, subject to consultation. Before the standard is brought into force, a review of the HHSRS is expected to take place to update and clarify the criteria.

This is a long lead time by design — the government recognises that significant numbers of private rented properties will require improvement, and that landlords need time to plan and invest.

EPC C by 2030: Separately, the government has set a target that all privately rented properties must achieve a minimum EPC rating of C by 2030. This is expected to be phased, with new tenancies required to meet the standard earlier. EPC C aligns closely with the thermal comfort criterion in the Decent Homes Standard. Meeting one effectively contributes to meeting the other.

What Landlords Should Do Now

The 2035-2037 window may feel distant, but the properties most likely to fail the Decent Homes Standard are those that require the most investment — investment that takes time to plan, fund, and carry out. Landlords who leave preparation to the last few years will face compressed timescales, higher contractor costs during periods of peak demand, and limited access to grants.

Audit Your Portfolio Against the Four Criteria

Walk through each property and ask:

| Criterion | Questions to ask | |---|---| | HHSRS Category 1 hazards | Is there damp, mould, cold, electrical risk, or structural defect present? | | Reasonable repair | Are the roof, structure, windows, doors, and key systems in good condition? | | Modern facilities | How old is the kitchen? The bathroom? The heating system? | | Thermal comfort | What is the EPC rating? Can the property retain heat adequately? |

Properties that clearly fail one or more criteria should be prioritised for investment planning now.

Track Your EPC Ratings

Every property in your portfolio should have a current, valid EPC. Properties rated D or below need a plan to reach C by 2030. Common improvement measures include:

• Loft and wall insulation
• Upgrading to a modern, high-efficiency boiler
• Double or triple glazing
• Heat pumps (where practical)

Some of these improvements attract government grants. Check the current availability of the Boiler Upgrade Scheme and the Energy Company Obligation (ECO4) before commissioning works.

Record Improvements and Maintenance

Keep a clear record of all maintenance, repairs, and improvements. If a council or tribunal ever asks whether your property meets the Decent Homes Standard, documented evidence of compliance will be your primary defence.

Plan Finances Over a Multi-Year Window

Major works — new kitchens, bathroom refits, roof repairs, full insulation packages — are expensive. A 10-year lead time is an opportunity to phase investment sensibly rather than absorb it all at once.

Summary

The Decent Homes Standard is coming to the private rented sector. The four criteria — freedom from Category 1 hazards, reasonable repair, modern facilities, and thermal comfort — set a clear benchmark for what an acceptable property must offer. The proposed implementation window of 2035 to 2037 provides time to prepare, but not time to ignore. Landlords who treat this as a long-term asset management question, rather than a last-minute compliance exercise, will be in a significantly stronger position.
