The Lifestyle Defense Dead End: Navigating the Ban on Blaming Tenants for Damp

The “Lifestyle” Excuse: Why It No Longer Works
We’ve heard it a thousand times. A tenant complains about black mould creeping up the bedroom wall. The landlord or agent visits, takes a quick look, and delivers the verdict: “You’re drying clothes on the radiator. It’s your lifestyle.”
For years, this was the standard response. It shut down conversations and left tenants feeling guilty while the fungus kept growing. But as of 2026, that argument is effectively dead in the water.
Here in London, we treat properties every week where this exact scenario played out. Just last Tuesday, we were in a flat in Ealing. The tenant had been told for two years that her boiling pasta water was rotting the window frames. When we stripped it back? The external pointing had failed. Rainwater was soaking the brickwork. No amount of opening windows would have fixed that.
The government’s crackdown on the “lifestyle defense” isn’t just red tape. It’s a recognition of a simple fact: Buildings must be able to cope with normal human living.
What the Rules Actually Say
Following the tragic death of Awaab Ishak and the subsequent legal changes (including Awaab’s Law), the guidance is crystal clear. Landlords and housing providers can no longer automatically blame tenants for damp and mould.
The Core Principle: It is unreasonable to expect tenants not to cook, wash, or dry clothes inside if the property doesn’t provide adequate means to do so without causing damp.
If a property cannot handle the moisture generated by a family living a normal life, the property is considered defective. The focus has shifted entirely from “how is the tenant behaving?” to “is the building performing?”
This means:
- Investigate first, blame later: You cannot assume lifestyle is the cause without ruling out structural issues.
- Adequate ventilation is key: Does the flat have working extractor fans? Are trickle vents blocked or non-existent?
- Heating matters: Is the heating system capable of keeping the home warm enough to prevent condensation?
Structural Faults vs. Living Habits: Knowing the Difference
Understanding the source of the damp is what we do best. While the law protects tenants, it helps everyone to know what we are looking at. Damp generally falls into categories, and most of them are structural.
1. Penetrating Damp
This is moisture coming from outside. It looks like blotchy patches on walls, often darker when it rains.
Causes: Leaking gutters, cracked render, slipped roof tiles, or blown brickwork.
Verdict: 100% a building maintenance issue.
2. Rising Damp
Moisture drawn up from the ground through bricks. It rarely goes higher than a meter up the wall.
Causes: Failed damp proof course (DPC) or bridging (where ground level outside is higher than the DPC).
Verdict: Structural failure.
3. Condensation (The Grey Area)
This is where the “lifestyle” argument used to live. It happens when warm, moist air hits a cold surface. However, under the new rules, condensation is often viewed as a ventilation failure.
If a tenant is boiling soup with the window open and the fan on, and mould still grows, that’s not lifestyle. That’s a property with thermal bridging (cold spots in the walls) or inadequate insulation.
The “Breathing” Defense
We’ve actually seen reports blaming tenants for “breathing too much” in small rooms. This is exactly the kind of nonsense the new regulations are designed to stop. A bedroom must be ventilated well enough to handle two people sleeping in it.
Your Rights as a Tenant in 2026
If you are renting and spotting mould, you are in a stronger position than ever before. Here is how to handle it:
Report It Immediately
Don’t wait. Send an email with photos. Document the date you first noticed it. Written records are vital.
Challenge the “Lifestyle” Claim
If your landlord says “open a window,” politely remind them that you do, and the damp persists. Ask for a structural assessment.
Request Specific Repairs
Ask about the extractor fans. Are they humidistat-controlled? If not, the property might not meet current standards.
The Reality Check for Landlords
If you’re a landlord, this might sound like a headache. But honestly? It’s actually an opportunity to protect your asset. Blaming the tenant doesn’t stop the rot in your floorboards. Fixing the issue does.
We work with dozens of private landlords across London who have realized that fighting claims is more expensive than fixing fans.
- Protect Your Investment: Mould eats plaster and wood. Ignoring it destroys your property value.
- Avoid Legal Costs: With the Housing Ombudsman becoming more aggressive, fines for neglecting damp can run into the thousands.
- Keep Good Tenants: People leave mouldy homes. Voids cost money.
A simple mould removal survey can often identify a fix that costs less than a month’s rent. Maybe it’s a new PIV unit (Positive Input Ventilation) or resealing a window. It’s rarely as scary as you think, but ignoring it is dangerous.
Fixing the Root Cause
So, the ban on blaming tenants is here. What now? We need to solve the problem, not just paint over it.
Professional Diagnostics
You can’t fix what you don’t understand. We use thermal imaging and moisture mapping to see what’s happening behind the paint. Is that wall wet because of condensation or a pipe leak? The camera doesn’t lie.
The Treatment Plan
Once we know the cause, the fix is usually straightforward:
- Sterilisation: We remove the harmful spores safely.
- Ventilation Upgrade: Installing quiet, efficient fans that run automatically.
- Insulation: Treating cold spots where mould loves to grow.
- Structural Repair: Fixing the leak, the gutter, or the pointing.
Stop Scrubbing with Bleach
Whether you own or rent, please stop using bleach on porous walls. It bleaches the colour but leaves the roots. The water in the bleach actually feeds the fungus deep in the plaster. It will come back, often angrier than before.
Common Questions About the “Lifestyle” Ban
Does this mean tenants have no responsibility?
Not exactly. Tenants still need to act reasonably—like not turning off the extractor fans provided or blocking vents. But the burden of proof has shifted. The landlord must prove the building is structurally sound and ventilated before questioning tenant habits.
I’m a landlord. My tenant dries clothes indoors. What can I do?
You can’t just ban it if they have no outdoor space. You must provide a solution. This might mean installing a washer-dryer, improving ventilation with a powerful humidistat fan, or installing a PIV unit that cycles air constantly. If the house can’t handle drying clothes, the house needs upgrading.
What is Awaab’s Law?
It’s a piece of legislation requiring social housing landlords to investigate and fix reported damp and mould within strict time limits. While it specifically targets social housing, the principles are being applied by courts and the Ombudsman to the private rental sector too.
Can I withhold rent if there is mould?
We generally advise against withholding rent without specific legal advice, as it puts you at risk of eviction. Instead, use the council’s environmental health department to force repairs. They have significant power to serve improvement notices.
How do I know if the damp is structural?
Look for patterns. Is it only on external walls? Does it get worse after rain? Is the plaster bubbling or salty? These are signs of water ingress, not condensation. A professional moisture survey can confirm this definitively.
Moving Forward Together
The “Lifestyle Defense” dead end is actually a good thing. It forces us to look at the quality of our housing stock in London. Damp homes aren’t just unpleasant; they are health hazards.
By removing the easy excuse of blaming the tenant, we focus on the real issue: creating dry, warm, breathable homes. Whether you are a worried tenant or a responsible landlord, the goal is the same.
At Mould Removal Specialists, we’ve been navigating these complex situations since 2014. We don’t take sides; we just find the water and stop it.
