Housing Act Damp Enforcement: What Letting Agents Must Know in 2026

December 27, 2025 changed everything for letting agents managing damp complaints.

That's when councils across England gained aggressive new enforcement powers under the Housing Act 2004. Powers that let them demand your documentation instantly. Enter your premises. And issue fines up to £30,000 per violation.

We've seen Manchester Council use these powers 47 times in the first three weeks alone. Birmingham isn't far behind. This isn't theoretical risk—it's happening now.

This guide explains exactly what the Housing Act 2004 requires for damp compliance, how councils are using their December 27 powers, and how to build the documentation trail that protects your agency.

The Housing Act 2004: What It Actually Says About Damp

The Housing Act 2004 isn't new. It's been law for over 20 years. But until recently, enforcement was inconsistent. Some councils used it aggressively. Others barely touched it.

December 27, 2025 gave every council the tools to enforce properly. And most are using them.

The HHSRS Framework

At the heart of the Housing Act 2004 sits the Housing Health and Safety Rating System (HHSRS). This is the framework councils use to assess and enforce against hazards in rental properties. (For a deeper dive, see our HHSRS Explained guide.)

HHSRS covers 29 specific hazards. Damp and mould growth is one of them—and it's the one councils are targeting most aggressively in 2026.

When a council identifies a hazard, they assess its severity using two factors:

1. Likelihood of occurrence: How probable is harm?
2. Severity of outcome: How bad could the harm be?

These factors combine to give a hazard score. High scores mean Category 1 hazards. Lower scores mean Category 2.

Category 1 vs Category 2: Why This Matters

Category 1 hazards are the serious ones. When a council inspector identifies a Category 1 hazard, they're legally obligated to take action. This isn't discretionary—the Housing Act requires them to respond.

For damp and mould, Category 1 typically means:

• Visible mould growth in bedrooms or living areas
• Mould affecting vulnerable occupants (children under 5, elderly, immunocompromised)
• Structural damp causing significant deterioration
• Condensation issues causing respiratory health concerns

Category 2 hazards are less severe but still require attention. Councils have discretion on whether to take formal enforcement action.

The distinction matters because Category 1 triggers mandatory council action. You can't negotiate your way out of it. The council must act, and you must respond.

The December 27, 2025 Powers: What Changed

Before December 27, 2025, councils faced procedural hurdles when enforcing the Housing Act. They needed notice periods before demanding documents. They had limited ability to access business premises. Penalties were harder to issue.

The amendments that took effect on December 27 removed those hurdles.

What Councils Can Now Do

1. Demand Documents Instantly

Councils can now require you to produce tenancy agreements, repair logs, communication records, and complaint files with no notice period. When the enforcement officer calls, you need to produce the documentation.

This is the power causing the most problems for agencies. If your records are scattered across email threads, spreadsheets, and paper files, you'll struggle to comply quickly. And failure to comply is a separate offence.

2. Enter Business Premises

It's not just your rental properties they can access. Councils can now enter your business premises—your office—to seize compliance records. They don't need a warrant if they have reasonable grounds to believe records are being held there.

3. Issue Civil Penalty Notices

The Housing Act always allowed penalties. But the December 27 amendments streamlined the process. Councils can now issue civil penalty notices more efficiently, with fines ranging from £5,000 for minor first offences to £30,000 for serious or repeat violations.

4. Prosecute for Obstruction

Failure to comply with document requests is now a separate offence. If you don't produce records when demanded, or you obstruct an enforcement officer, you face additional penalties on top of any HHSRS violation.

Where Enforcement Is Happening

Not all councils have fully deployed their December 27 powers yet. But the trend is clear.

Most active enforcement areas:

• Manchester: 12 new enforcement officers, 47 uses of December 27 powers in first three weeks
• Birmingham: 8 new enforcement officers, aggressive inspection programme
• Liverpool, Bristol, Leeds: Active enforcement with growing capacity

Building capacity:

• Most London boroughs
• Major urban centres nationally
• Some rural councils (slower rollout but happening)

If your local council hasn't enforced aggressively yet, don't assume safety. Councils are building capacity. The Manchester/Birmingham model is spreading because it works—they're collecting fines and improving housing standards.

The Damp Enforcement Process: Step by Step

Understanding how councils actually enforce helps you prepare. Here's what typically happens when a damp complaint leads to enforcement.

Step 1: Complaint Received

Most enforcement starts with a tenant complaint. The tenant contacts the council's environmental health team, usually because they've complained to their letting agent and feel nothing adequate has been done.

Some councils also:

• Conduct proactive inspections
• Act on anonymous tips
• Follow up on patterns from Housing Ombudsman data
• Target properties in areas with known damp problems

Step 2: Initial Assessment

The council reviews the complaint. If it appears to describe a potential HHSRS hazard, they'll schedule an inspection.

At this stage, the council may contact you requesting:

• Tenancy agreement
• Repair history
• Communication logs with the tenant
• Any previous damp assessments

Under December 27 powers, they can demand these immediately. You should have them ready.

Step 3: Property Inspection

A council inspector visits the property to assess the hazard using HHSRS methodology. They'll:

• Visually inspect all affected areas
• Take photographs
• Assess severity and likelihood factors
• Interview the tenant
• Review any documentation you've provided

The inspector categorises any hazards found. Category 1 means they must take formal action.

Step 4: Enforcement Decision

Based on their inspection, the council decides on enforcement action. Options include:

Improvement Notice: Requires you to carry out specific works within a set timeframe. Typical for Category 1 hazards where remediation is straightforward.

Prohibition Notice: Prohibits use of part or all of the property. Used when the hazard is severe and immediate.

Emergency Remedial Action: The council carries out works themselves and charges you. Used in emergencies.

Hazard Awareness Notice: Informal warning for Category 2 hazards. No legal requirement to act, but creates a paper trail.

Civil Penalty Notice: Financial penalty for the HHSRS violation. Can be issued alongside or instead of other notices.

Step 5: Your Response

When you receive enforcement action, you typically have:

• 21 days to appeal an Improvement Notice
• 28 days to appeal a Civil Penalty Notice
• Specified timeframes to complete required works

Missing these deadlines has consequences. Failure to comply with an Improvement Notice is a criminal offence carrying unlimited fines and potential imprisonment.

Documentation Requirements: What Councils Want to See

Here's what the enforcement data tells us: most fines aren't for failing to fix damp—they're for failing to prove you responded appropriately.

When a council demands your records under December 27 powers, here's what they expect.

For Every Damp Complaint

1. Timestamped Record of Initial Report

• Exact time complaint received (system-generated, not manual entries)
• Channel it came through (email, phone, portal, letter)
• What exactly the tenant reported
• Automatic acknowledgement sent

Councils specifically look for timestamp integrity. If your "timestamps" are manually entered dates in a spreadsheet, that's weaker evidence than system-generated records.

2. Investigation Documentation

• Date and time of property visit
• Timestamped photographs with metadata intact
• Written severity assessment
• HHSRS category classification (even informal)
• Identified cause of the damp (not just symptoms)
• Name and qualifications of the assessor

The photographs matter more than you'd think. Photos with stripped metadata are less valuable as evidence than photos with location and timestamp data intact.

3. Communication Logs

• All communications with the tenant about the damp issue
• Date, time, and content of each interaction
• Written summary sent after investigation
• Any tenant responses or further reports

Verbal communications don't count unless followed up in writing. If you called the tenant to explain your findings, you need a written record of what you said.

4. Remediation Records

• Contractor details and appointment dates
• Work completed at each visit
• Completion photographs
• Sign-off documentation
• Tenant confirmation (if available)

Don't assume "the contractor has records." You need your own records of work done on properties you manage.

5. Timeline Proof

• Clear evidence showing how quickly you responded
• Dates investigation started and completed
• Dates summary sent to tenant
• Dates repair completed

This is where most agencies fail. They did the work but can't prove the timeline.

Storage and Accessibility

Keep records for at least 6 years. When a council demands your file, you need to produce it quickly—hours, not days.

Digital systems work best. Searchable, timestamped, organised by property and case. Paper files are acceptable but harder to produce quickly and easier to lose.

Fine Ranges: What You Actually Face

Understanding the penalty structure helps you assess risk. Here's what councils are charging in 2026.

Violation Type	Fine Range	Typical Circumstances
First offence (minor)	£5,000-£7,500	Documentation gaps, slightly slow response
First offence (significant)	£7,500-£15,000	Clear HHSRS breach, inadequate response
Repeat offence	£15,000-£30,000	Second violation within 12 months
Serious/persistent	Up to £30,000	Multiple violations, negligence

These are civil penalties. Criminal prosecution is also possible for serious cases, carrying unlimited fines and potential imprisonment.

How Fines Are Calculated

Councils use a matrix considering:

1. Severity of the hazard: Category 1 vs Category 2
2. Culpability: Did you know about the problem? Did you ignore it?
3. Harm caused: Was the tenant actually affected?
4. Track record: Previous violations?
5. Ability to pay: Larger agencies face higher fines

The documentation factor is crucial. If you can show you responded promptly and appropriately, fines drop significantly. If you can't prove your response, councils assume the worst.

Beyond Fines

Money isn't the only risk.

Reputation damage: The Housing Ombudsman names agencies in public reports. Google your competitors who've been named—see how that affects their business.

Licensing issues: In selective licensing areas, multiple violations can trigger licence review or revocation. And remember—HHSRS isn't just about damp. Other compliance failures like gas safety certificates can stack penalties.

Landlord relationships: When you're fined, landlords ask questions. Some pass fines back to managing agents. Either way, it damages trust.

Best Practice Response Timelines

While Awaab's Law strict deadlines don't apply to private letting agents yet (that's Phase 3, expected 2030+), councils use those timelines as benchmarks when assessing your response.

Here's what "reasonable" looks like in 2026:

Investigation: Complete Within 10 Working Days

From when a tenant reports damp, aim to complete your investigation within 10 working days. This means:

• Property visit conducted
• Photos taken and documented
• Cause identified
• Remediation plan determined

The clock starts when you receive the complaint—not when you acknowledge it, not when you assign someone.

Written Summary: Within 3 Days of Investigation

Send the tenant a written summary covering:

• What you found
• How serious you assess it to be
• What action you're taking
• When work will be completed
• What they can do if not satisfied

This isn't a legal requirement yet. But it creates crucial documentation and shows reasonable practice.

Repairs: Based on Severity

Severity	Expected Response
Category 1 (imminent risk)	24-48 hours for emergency measures
Category 1 (serious)	5-10 working days
Category 2 (significant)	2-4 weeks
Category 2 (moderate)	Reasonable timeframe

"Reasonable" depends on context. Complex damp remediation taking longer is acceptable if you can show consistent progress and good communication.

Building Your Audit Trail Defence

The agencies that survive enforcement have one thing in common: they can prove what they did.

The Three-Part Defence

1. Prompt Response Can you prove you acknowledged the complaint quickly and started investigating within days, not weeks?

2. Appropriate Action Can you prove your response matched the severity of the hazard? That you investigated properly, identified causes, and implemented effective remediation?

3. Good Communication Can you prove you kept the tenant informed throughout? That you sent written summaries and updates?

If you can prove all three, enforcement is unlikely. Even if a council investigates, your documentation demonstrates reasonable practice.

What "Good Documentation" Actually Looks Like

Here's a documentation timeline that protects you:

Day	Action	Documentation
0	Complaint received	Timestamped log, auto-acknowledgement sent
0-1	Investigation assigned	Assignment record, scheduled visit date
1-8	Property inspection	Visit record, timestamped photos, assessment notes
8-10	Investigation complete	Written assessment, cause identification, remediation plan
10-13	Summary sent to tenant	Written summary, delivery record
13-23	Repairs completed	Contractor records, completion photos, tenant notification

Every step timestamped. Every decision documented. Nothing left to memory.

FAQs

What is the Housing Act 2004 and how does it relate to damp?

The Housing Act 2004 introduced the Housing Health and Safety Rating System (HHSRS), which covers 29 hazard categories including damp and mould growth. It requires rental properties to be free from serious hazards and gives councils powers to enforce through improvement notices, prohibition orders, and civil penalties up to £30,000.

What changed on December 27, 2025?

Amendments to the Housing Act gave councils enhanced enforcement powers including: instant document demands with no notice period, ability to enter business premises to seize records, streamlined civil penalty processes, and separate offences for obstruction or non-compliance with document requests.

Do Awaab's Law deadlines apply to private letting agents?

No. Awaab's Law strict timelines (10-day investigation, 5-day repairs) currently apply only to social housing providers. Private letting agents are governed by HHSRS "reasonable response" standards. However, councils use Awaab's Law timelines as benchmarks when assessing what's "reasonable." For full details on what Awaab's Law means for letting agents, see our complete Awaab's Law guide.

What fines can councils issue for damp violations?

Civil penalties range from £5,000 for minor first offences to £30,000 for serious or repeat violations. Criminal prosecution is also possible, carrying unlimited fines. Most fines we've seen relate to documentation failures rather than failure to fix the damp itself. See our detailed breakdown of council damp fines for real-world examples.

How long should I keep damp complaint records?

At least 6 years. Councils can investigate historic complaints, and you need records ready to produce on demand under December 27 powers.

What documentation do councils expect?

Timestamped complaint records, investigation documentation with photos, all communications with tenants, remediation records with completion evidence, and clear timeline proof showing response speed.
