Decent Homes Standard: What Private Landlords Must Know in 2026

The Decent Homes Standard has applied to social housing in England since 2006. Under the Renters’ Rights Act 2025, it extends to the private rented sector from May 2026. Every landlord must now meet minimum conditions that were previously only required of councils and housing associations.

Most well-maintained properties will already meet the standard without changes. But if your property has outstanding hazards — particularly damp, cold, or electrical issues — you need to act before enforcement begins.

What the Decent Homes Standard Requires

A property meets the Decent Homes Standard if it satisfies four criteria:

1. Free from Category 1 hazards

Category 1 hazards under the Housing Health and Safety Rating System (HHSRS) are the most serious risks to health and safety. A decent home must not have any Category 1 hazards present.

These are assessed by the council on a sliding scale of risk. The most common Category 1 hazards in the private rented sector are:

Hazard	Common causes
Excess cold	Poor insulation, no central heating, inefficient boiler
Damp and mould	Structural damp, condensation from inadequate ventilation
Falls — stairs and steps	Inadequate handrails, uneven or damaged stairs
Electrical hazards	Outdated wiring, overloaded circuits, uncertified installation
Fire	No smoke alarms, inadequate escape routes, combustible materials
Carbon monoxide	Faulty boilers or gas appliances without CO detection
Structural collapse	Subsidence, serious disrepair to roof, floors, or walls

A Category 2 hazard is a less serious risk. The standard requires absence of Category 1 hazards — Category 2 hazards are not automatically a problem, though councils can still take action on them.

2. In reasonable repair

The property must not be in a state of serious disrepair. This means major building components — roof, structure, walls, windows — must not be in serious deterioration or requiring urgent replacement.

This is a lower bar than it sounds. It does not mean the property must be newly renovated. It means it must not be crumbling.

3. Reasonably modern facilities

The property must have reasonably modern kitchen and bathroom facilities. The kitchen and bathroom must not be excessively old and worn out. In practice, this means:

• Kitchen: not more than approximately 30 years old and in adequate working order
• Bathroom: not more than approximately 30 years old and in adequate working order
• Adequate noise insulation between floors (for flats)

4. Thermally comfortable

The property must have an effective and efficient heating system — capable of warming the home to a reasonable standard without excessive cost. It must also have adequate insulation (loft, walls where possible) to retain heat.

Practically, this means a functioning central heating system or equivalent, with appropriate levels of insulation. An EPC rating of E or above is an indicator, though not the formal measure.

HHSRS — The Assessment Framework

The Housing Health and Safety Rating System (HHSRS) is how councils assess hazards. An inspector visits the property, assesses each potential hazard category against a scoring matrix, and calculates a risk score. High-scoring hazards become Category 1.

You can request an HHSRS assessment from your local council. Some councils offer these proactively as part of landlord support services. It is worth getting one if you are unsure about your property’s status.

Private surveyors also offer HHSRS assessments for a fee. If you have doubts about specific hazards — particularly damp, cold, or electrical — a professional assessment gives you clarity and something to show an inspector.

The Most Common Problems in Private Rentals

Damp and mould

The single most common Category 1 hazard in private rentals. Damp can be:

• Rising damp — from the ground through inadequate damp proof course
• Penetrating damp — from external water ingress (leaking roof, defective rendering)
• Condensation — from poor ventilation, especially in bathrooms and kitchens

Rising and penetrating damp are structural problems. They require remediation, not just repainting over mould. Condensation damp can often be addressed through improved ventilation — extractor fans, trickle vents, dehumidification — but requires honest assessment of the root cause.

The damp and mould guide covers this in detail.

Excess cold

A property that cannot maintain adequate indoor temperatures is a Category 1 hazard. Councils apply a standard of 21°C in the main living room and 18°C in other occupied rooms in winter.

Properties most at risk: older houses with single-glazed windows, solid walls without insulation, and old or unreliable boilers. If your boiler is over 15 years old or if tenants regularly complain of cold, have the system professionally assessed.

Electrical hazards

If your EICR (Electrical Installation Condition Report) has identified Category C2 or C1 defects that have not been remediated, your property likely has an electrical hazard. An up-to-date EICR with all defects remediated is the starting point.

EICR is now a legal requirement (5-yearly), so this should already be in hand. If you have an outstanding EICR, get it done now.

Enforcement and Consequences

Local councils enforce the Decent Homes Standard through the HHSRS framework. Their powers include:

Action	When used	Effect
Improvement Notice	Category 1 or 2 hazard	Requires landlord to fix within a set period
Prohibition Order	Serious hazard making property uninhabitable	Prevents use of part or all of property
Emergency Remedial Action	Immediate risk to health	Council carries out work and recoups costs
Civil Penalty Notice	Failure to comply	Up to £30,000 per offence
Prosecution	Serious breach	Criminal conviction and unlimited fine

Additionally, tenants whose landlord is served with an Improvement Notice and fails to comply within the specified period can apply for a Rent Repayment Order — reclaiming up to 12 months of rent.

The financial stakes are significant. A £30,000 civil penalty plus potential rent repayment for an uncompliant property is a serious outcome for what might have been a fixable issue.

What to Do Before May 2026

1. Inspect your property honestly. Walk through it looking at it from an enforcement perspective. Is there any visible damp or mould? Are there draughty single-glazed windows without any secondary glazing? Is the heating system functional and maintained?

2. Fix Category 1 hazards now. If you know there is a problem — a damp wall, a broken boiler, an overloaded fuse board — fix it before May 2026. Enforcement will be keener after the standard formally applies.

3. Get your EICR done if overdue. If your electrical report is more than 5 years old or if it has outstanding defects, this is the priority. An electrical hazard is one of the most serious Category 1 items.

4. Review your EPC. An EPC F or G rating is a strong signal of excess cold risk. If your property is rated F or below, the insulation and heating will likely need attention anyway given forthcoming EPC minimum requirements.

5. Document improvements. If you remediate hazards, keep records — contractor invoices, before-and-after photos, inspection reports. This shows compliance if council inspectors visit.

Compliant Properties Have Nothing to Fear

If your property is well-maintained, has current safety certificates, and does not have outstanding damp, heating, or electrical problems, the Decent Homes Standard changes very little for you in practice. The standard codifies what conscientious landlords are already doing.

The point of it is to remove the floor — to ensure there is no legal property available to tenants that is also a hazard to their health. That is a reasonable goal, and the majority of self-managing landlords who take their responsibilities seriously are already there.
