Risk of flooding

With severe weather events becoming more frequent, flooding is a growing concern for property owners across the UK. Recent climate reports confirm a trend towards wetter conditions over the past few decades, increasing the risk of flood damage. This threat is not limited to properties near rivers or coastal areas; intense rainfall can overwhelm drainage systems anywhere, leading to surface water flooding that can render a property uninhabitable.

For landlords, the consequences can be severe, involving costly repairs and displacement of tenants. Therefore, it is vital for every landlord to understand the risks and implement a robust flood preparedness strategy. This guide provides practical advice on assessing risk and taking preventative measures to reduce the likelihood and impact of flooding on your property.

The realities of flood risk

Flooding is one of the most severe threats to property, capable of making homes uninhabitable, displacing tenants, and causing major financial losses. While flood claims occur less frequently than other property claims, the impact of a single event can be substantial. Total Landlord’s 2025 claims data shows that the average flood-related payout was £1,015.66, though severe events have seen payouts exceed £100,000.

Current warnings

Flooding remains a major threat for property owners nationwide, with the impact stretching far beyond traditional high-risk areas. The Environment Agency continues to call on the public to remain aware of the potential for significant flooding, as warnings and alerts are consistently in place across England. As of February, there were 75 active flood warnings and 191 flood alerts, with additional rainfall and unsettled weather expected. While over 22,000 properties have been protected by defences, around 340 homes and businesses have suffered flooding during recent severe weather events.

Assess the flood risk to your property

Understanding your property's flood risk is a critical step. Utilise the UK Government’s free flood risk checking tool (available on GOV.UK) to determine your vulnerability to river, coastal, and surface water flooding.

By entering a postcode, you can assess the long-term risk from:

• Rivers and the sea
• Surface water
• Reservoirs
• Groundwater

If your property is flagged as high-risk, it does not necessarily mean it is uninsurable, but it does mean that standard maintenance may not be enough. You will need to implement a dedicated flood resilience strategy.

Building resilience: proactive measures

Investing in flood defences is often far more cost-effective than repairing water damage. We recommend a tiered approach to protection.

Exterior defence and maintenance

Your property’s exterior is the first line of defence.

• Clear drainage: As a landlord, you are responsible for the property's structure and exterior. This includes keeping gutters, downspouts, and drains clear of debris. Blockages are a common cause of avoidable water damage
• Permeable surfaces: If you are upgrading a driveway or patio, opt for permeable paving or gravel. This allows rainwater to drain naturally into the ground rather than pooling on the surface or running off into an overwhelmed sewer system
• Airbricks: Install covers for airbricks or replace standard ones with self-closing 'smart' airbricks that automatically shut off airflow when they detect rising water

Interior flood-proofing:

If you are refurbishing a property in an at-risk zone, consider flood-resilient materials.

• Flooring: Replace carpets with ceramic tiles, stone, or sealed concrete on the ground floor. These materials can be cleaned and disinfected after a flood, whereas carpets and laminate often require total replacement
• Electrical height: Raise electrical sockets, fuse boxes, and meters to at least 1.5 metres above floor level to prevent short circuits and fire hazards during shallow flooding
• Non-return valves: Installing non-return valves on waste pipes and toilet outlets prevents sewage from flowing back into the property, a particularly hazardous and costly consequence of sewer flooding
• Sump pumps: For properties with basements or those in low-lying areas, a sump pump system can automatically remove water that accumulates below floor level

Inform your tenants

Tenants play a critical role in preventing and responding to floods. It's important that they report maintenance issues that could increase the risk of flood damage promptly.

• The welcome pack: Include a flood safety section in your tenant welcome pack. This should detail the location of the main stopcock for water, the gas shut-off valve, and the fuse box
• Reporting protocols: Encourage tenants to report blocked drains or minor leaks immediately. A culture of early reporting allows you to fix issues before they exacerbate a flood event

When disaster strikes: response and recovery

If your property is hit by flooding, safety is the absolute priority.

During the flood

• Evacuation: Advise tenants to move to higher ground or a safe location immediately if instructed by emergency services
• Utilities: If safe to do so, gas, electricity, and water supplies should be turned off
• Avoid floodwater: Emphasise that tenants must not walk or drive through floodwater. Just 30cm of flowing water can move a car, and floodwater is often contaminated with sewage and hidden hazards

After the flood

Once the water recedes, the recovery process begins.

1. Documentation: Before beginning any cleanup, take comprehensive photographs and video evidence of all damage. This is crucial for your insurance claim
2. Contact insurer: Notify your insurance provider immediately. Total Landlord, for example, has dedicated teams to guide you through the claims process
3. Professional drying: Do not rush to redecorate. Professional drying and decontamination are essential to prevent mould and structural rot
4. Safety certification: A qualified electrician must test the electrical installation before power is restored

The importance of comprehensive landlord insurance

No property can ever be deemed completely safe from flooding, and even a single water-related incident can result in devastating financial losses. For landlords, investing in insurance is not just an option, it is essential. A comprehensive policy is your primary line of defence, providing reassurance that you can manage the financial aftermath of even the most severe flood events.

Total Landlord’s Premier policy offers wide-ranging protection, covering the cost of all necessary structural repairs following insured flood damage. The policy also includes loss of rent if tenants must move out during restoration, as well as expenses associated with providing alternative accommodation.

This protects that both your business continuity and your tenants’ welfare are prioritised throughout the recovery process. NRLA members enjoy an exclusive 15% discount when they take out a policy with Total Landlord. Whether you're new to the market or managing an expanding portfolio, Total Landlord has all the tools and services you need for a smooth, secure letting experience.

Key takeaways

Flooding poses an increasing risk for landlords as extreme weather becomes more common. Protecting your property requires a strategic approach: assess flood risk, invest in prevention, maintain your building, and secure comprehensive insurance, such as Total Landlord’s Premier policy. Clear communication with tenants and staying informed means you are prepared to respond swiftly, safeguarding your assets and tenants against the challenges of flooding.
