One in five privately rented homes in England don’t meet basic decency standards right now.
That’s 1.5 million rental properties that are too cold, too damp, or falling into disrepair. The reformed Decent Homes Standard was confirmed in January 2026, marking the first major update to the standard since 2006. It’s designed to tackle the 10% of social homes and 21% of privately rented homes currently classified as non-decent.
At Chameleon Technology, we have 15 years’ experience in home energy and environmental data, and it’s not hard to see the same compliance gaps appearing time and time again: thermal comfort issues, hidden damp risks, and inadequate heating systems.
Properties now have until 2035 to comply with the latest standard, or face fines of up to £40,000.
The biggest housing shake-up in 20 years
For the first time ever, the standard now applies to both social housing and the private rented sector.
The new standard moves away from box-ticking exercises and focuses on what actually matters: keeping homes safe, warm, and liveable. If you’re a housing provider, landlord, or property manager, you need to understand these changes.
What’s actually changed?
The reformed Decent Homes Standard updates the old four-point checklist to five modern criteria. The focus has shifted from arbitrary age limits to actual property conditions.
Here’s what properties must not include…
Criterion A: free from Category 1 hazards
This stays the same. Properties must be free from serious risks under the Housing Health and Safety Rating System (HHSRS). Think structural problems, dangerous electrics, or fire hazards.
Nothing new here, but enforcement is getting stricter.
Criterion B: reasonable state of repair
This is where things start to differ. The government has removed age as a consideration in this criterion, so components will only be assessed on their condition.
No more replacing perfectly good kitchens just because they hit a magic number.
Building components are now judged on whether they actually work, not how old they are. A 25-year-old kitchen in excellent condition? That’s fine. A seven-year-old one falling apart? That needs fixing.
Criterion C: modern facilities
Flats must provide at least three of the following: a kitchen with adequate space and layout, an appropriately located bathroom and WC, adequate external noise insulation, and adequate size and layout of common entrance areas.
Properties must meet minimum facility requirements that differ by type.
Note: The government will publish detailed criteria for what constitutes “adequate” in each category. In the meantime, assess against current building regulations and common-sense functionality.
Criterion D: thermal comfort and energy efficiency
Properties must meet Minimum Energy Efficiency Standards (MEES) with programmable heating throughout.
This ties into the government’s push for all rented properties to reach EPC C or equivalent by 2030. Properties need proper insulation, efficient heating, and residents must be able to control their own warmth.
Monitoring temperature data across your properties can help identify cold spots before they become compliance issues. Chameleon’s Gateway devices capture real-time temperature and humidity data, giving housing providers early warning of potential problem areas.
Criterion E: free from damp and mould (NEW)
This is the big addition. Any home with a damp and mould hazard assessed within bands A to H of the HHSRS would fail this criterion.
The tragic death of Awaab Ishak brought damp and mould into sharp focus. Properties must now actively prevent hazardous damp and mould, not just react to tenant complaints.
This works alongside Awaab’s Law, which sets strict timescales for fixing damp and mould once reported.
Who does this apply to?
The Decent Homes Standard applies to rented properties in England. Scotland, Wales, and Northern Ireland have separate housing standards.
The new Decent Homes Standard will apply from 2035 to both the social and private rented sectors. Social housing providers and private landlords are all playing by the same rules now.
This ensures that all rentals are now held to the same standard, giving tenants a clear standard of home quality regardless of who their landlord is.
What are the penalties?
Local councils can issue immediate civil penalties of up to £7,000 for serious failures including Category 1 hazards. For other offences, maximum penalties can reach £40,000.
Councils can issue these fines directly without going through the courts. For repeat offenders or serious violations, landlords can be criminally prosecuted, and tenants or councils can apply to the First-tier Tribunal for rent repayment orders.
How to start preparing now
If you’re a landlord or housing provider, you have until 2035 to enact these changes – but that doesn’t mean you should wait.
Here’s your action plan
Audit Your Current Stock
Walk through every property and assess condition, not age. The original consultation estimated that 79% of properties in the private rented sector already meet the current standard, meaning 21% will need upgrades.
Once you have an up-to-date baseline of property conditions, you can begin to focus your attention on the ones that need the most intervention.
Focus on damp and mould first
This is the new criterion causing the most concern. Install proper ventilation if it’s missing, fix leaks promptly, and monitor humidity levels. Our new Gateway Connect devices can be posted directly to homes, and simply need plugging in by the tenant. It wirelessly connects to the home’s smart meter, if it has one, and begins to collect temperature and humidity data via in-built sensors.
Real-time environmental monitoring helps catch problems early. Temperature and humidity sensors can flag properties at risk of condensation and mould before visible damage appears.
Plan your energy efficiency upgrades
With MEES changes coming by 2030 and the Decent Homes Standard arriving in 2035, energy efficiency work is a must. Combining these projects makes financial sense.
Better insulation, efficient heating systems, and smart controls all count towards compliance.
Keep detailed records
Document every repair, upgrade, and inspection. When councils start enforcing the standard, you’ll need evidence that you’ve been maintaining properties properly.
Engage with tenants
Your tenants live in these properties every day. They know where the cold spots are, where condensation forms, and which facilities aren’t working properly. Lean into this experience and involve your tenants as you develop improvement plans.
Why compliance delivers more than just penalty avoidance
Beyond avoiding fines, there’s clear evidence that housing providers who exceed the standard see tangible business benefits.
Properties with documented compliance and quality improvements attract better tenants and command premium rents. You build a reputation that generates referrals and reduces marketing costs.
The broader societal benefits work in your favour too. Healthier tenants mean better employment outcomes and more stable rent payments. Reducing NHS costs from preventable housing-related illness benefits everyone.
Everyone deserves to live in warm, dry, and well-maintained homes. Meeting the standard delivers:
- Longer tenancies and lower void periods
- Improved reputation and stronger referral rates
- Lower heating bills for tenants from improved thermal efficiency, so tenants are more likely to be able to afford rent
- Fewer emergency interventions and compliance issues
- Premium positioning in a competitive market
What happens next?
The properties that exceed the standard will command premium rents and longer tenancies.
The standard is confirmed and will be enforced from 2035. Between now and then, the government will publish detailed guidance on implementation, assessment methods, and exemptions.
Landlords should not delay all action until the end of the implementation period. Start planning now, prioritise the worst performing properties, and work systematically through your stock.
The housing providers getting ahead of this now will find 2035 far less stressful than those scrambling at the last minute.
Making compliance easier
Data-driven property management helps you prioritise resources, catch problems early, and prove compliance. Understanding which properties struggle with thermal efficiency, where humidity levels spike, and which homes need attention first makes the whole process more efficient.

The new Decent Homes Standard sets a new baseline for rental property quality. Housing providers who embrace these changes early will find themselves ahead of the curve, with happier tenants, lower maintenance costs, and zero compliance headaches come 2035.
