Damp, Mould & £7,000 Fines: Why London Landlords Should Be Paying Attention in 2026
November 2026 | Property News & Building Maintenance
The rules around property safety are changing — and landlords across London have good reason to pay attention.
With tougher enforcement measures already in place and proposals to extend Awaab's Law to private rented homes, property maintenance is becoming an increasingly important responsibility for landlords and managing agents.
But what do these developments actually mean for property owners in Chelsea, Kensington and across Greater London?
What's Changed in 2026?
Since June 2026, local councils in England have been able to impose financial penalties of up to £7,000 for certain breaches involving serious hazards in privately rented homes.
These hazards can include dangerous damp and mould, electrical risks, fire safety concerns and unsafe building conditions.
In October 2026, the government also launched a consultation on extending Awaab's Law to private rented properties.
The law already imposes strict timescales for addressing specified hazards in social housing. Its proposed extension would bring further protections to private tenants, although the additional requirements are not yet in force for private landlords.
The message for property owners is clear: identifying and addressing building defects early is increasingly important.
Damp and Mould: More Than a Cosmetic Problem
A patch of mould on a bedroom wall may appear to be a minor decorating issue.
However, the underlying cause could involve:
Water penetration through damaged external walls
Leaking gutters or defective roof coverings
Inadequate ventilation
Plumbing leaks
Condensation and thermal bridging
Deteriorated rendering or external finishes
Simply painting over the affected area rarely provides a lasting solution if the underlying moisture problem remains unresolved.
Effective remediation begins with identifying the cause and selecting appropriate repairs.
Five Property Issues Landlords Shouldn't Ignore
1. Damp and water ingress
Unresolved moisture problems can damage finishes, timber and internal building materials.
2. Roofing and guttering defects
Blocked gutters, damaged flashings and deteriorated roof coverings can allow rainwater to enter the building.
3. Electrical safety concerns
Damaged accessories, exposed wiring and other visible warning signs should be referred to a qualified electrician.
4. Unsafe stairs and deteriorating building elements
Loose handrails, damaged steps, defective flooring and unstable components can create avoidable safety risks.
5. Poor ventilation and recurring condensation
Ventilation problems can contribute to persistent moisture and mould growth, particularly in bathrooms, kitchens and bedrooms.
Why Preventative Property Inspections Matter
Many significant maintenance problems begin as small, easily overlooked defects.
Regular visual property assessments can help identify signs of deterioration before more extensive repairs become necessary.
For landlords and property managers, a documented inspection also helps establish maintenance priorities and prepare realistic repair budgets.
However, a general visual assessment does not replace legally required electrical, gas, fire safety or specialist building inspections.
