The ultimate guide to safeguarding your property from flood damage

Flooding, driven by severe weather and heavy rainfall, is becoming increasingly common across the UK. Although there is significant variation from year to year, the Met Office records January rainfall as well above average in large parts of southern England, eastern Scotland, and Northern Ireland.  

Met Office science manager Dr Amy Doherty states:  

“January has been exceptionally wet because we’ve seen a very persistent Atlantic weather pattern. A strong jet stream has repeatedly steered low-pressure systems towards the UK, bringing frequent spells of rain and wind.”

While certain regions are more vulnerable to floods, the risk extends beyond the typical riverside towns or coastal areas known for high tides. Even if your property isn't situated on a floodplain, the potential for flooding exists. Severe flooding can happen without warning as heavy rain, particularly on already saturated ground, can lead to rising groundwater causing burst water mains and backed-up sewers, resulting in surface water that could have a devastating impact almost anywhere, making properties completely uninhabitable and leading to serious repercussions for landlords and tenants.

It's essential for all landlords, not just those in high-risk zones, to be prepared for flooding and to make sure that their properties and tenants are ready to respond.

In this detailed guide, we’ll provide advice on flood risk assessment, preventative measures, emergency protocols, and how to make sure you have comprehensive insurance coverage.

Flood facts and figures

Currently, 2.8 million people are particularly vulnerable to surface water flooding and one in six homes is located in a high-risk area. The Environment Agency has urged the public to remain vigilant as the risk of significant flooding continues across England, with warnings and alerts still in place nationwide. As of February, 68 flood warnings and 150 flood alerts were active, and further rainfall combined with unsettled weather conditions is forecast.

Since late January, an estimated 390 properties have been recorded as flooded, while more than 24,500 have been protected by flood defences. However, the Environment Agency has stated that these figures are subject to change as teams continue to verify impacts on the ground.

Floods Minister Emma Hardy said:

“To protect homes and businesses from future flooding situations, this government is investing a record £10.5 billion to protect a further 900,000 properties by 2036. This is alongside reprioritising over £100 million to maintain existing flood assets.”

Claims can be costly, with the average flood claim at Total Landlord rising from £13,739 (2017–2021) to over £38,000 in recent years.

How can landlords protect their properties from flood damage?

1.  Assess your flood risk

Before taking any steps, landlords should assess the flood risk to their property. Some areas are more susceptible than others, so it's essential to determine your property's vulnerability. The UK Government provides a free service to check flood risk at GOV.UK. If you own property in a high-risk area, consider implementing long-term flood resilience measures to reduce potential damage.

"Landlords with properties in high-risk areas should invest in flood-proofing improvements and bolster their insurance coverage. The initial cost of these measures may seem steep, but if severe flooding occurs, it will be well worth it."

2.  Take preventative steps

To protect your property from flood damage, landlords, especially those in high-risk zones, can implement a variety of measures:

  • Use permeable materials for driveways and paths
  • Install water-resistant windows, doors, and airbricks
  • Fit non-return valves for toilets and sewer pipes to prevent sewage backups
  • Install sump and pump systems to remove water from below floor level
  • Consider adding waterproof doors, skirting boards, and wall sealants
  • Opt for water-resistant flooring, such as stone or ceramic tiles, rather than wood or carpets
  • Raise electrical sockets and use high shelves or wall mounts for valuable items
  • Seal windows and external doors
  • Install flood alarms
  • Provide modern sandbags for tenants to block water from entering through doors and vents

By adopting these strategies, landlords can minimise flood risk and damage. More guidance on flood protection can be found through the Property Care Association.

3.  Keep tenants informed

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. If your property is in a flood-prone area, it's advisable to provide tenants with clear instructions, both verbally and in writing, on what to do in case of flooding.

Steve Barnes underscores the importance of communication:

"As extreme weather becomes more common, landlords must educate tenants, particularly if the property is far from their residence. Tenants should have access to sandbags and know how to shut off gas, electricity, and water in an emergency."

Regular maintenance and proper communication with tenants are both crucial to reducing potential damage. It’s a good idea to provide your tenants with a welcome pack which includes any relevant information and instructions on what to do in the event of a flood.

4. Carry out regular maintenance to reduce flood damage

Landlords are responsible for maintaining external structures like drains and gutters. Keeping these clear helps water flow away from the property during heavy rain. Check gutters, downspouts and drains regularly to avoid blockages that can lead to floods.

Routine drain maintenance is essential. Clogged drains, even from minor debris, can cause flooding if water levels rise quickly during a storm. It's important to note that flood insurance does not cover damage caused by neglect or wear and tear, so staying on top of maintenance responsibilities is key.

5. Sign up for flood warnings

The Government provides a free flood warning service on GOV.UK. By signing up, landlords and tenants can receive alerts about imminent floods in their area. This service covers risks from rivers, the sea, and groundwater, and helps to prepare for potential flooding.

The Environment Agency has highlighted the impact of flood damage on mental health, advising people of the importance of signing up to flood alerts. Low income households are amongst the most at risk of flooding and 61% of low-income renters don’t have home contents insurance.

What to do if a flood affects your property

If there is a flood impacting your property, the priority is safety. Here’s what to advise tenants in case of a flood:

  • Move to higher ground if needed or evacuate the property
  • Turn off gas, electricity, and water if safe to do so
  • Avoid contact with floodwaters, which may be contaminated
  • Follow emergency services’ instructions

Once the immediate danger has passed, landlords should:

  • Take photos to document the damage
  • Contact the insurance provider to begin the claims process
  • Hire professionals to pump out water and dry the property
  • Have an electrician check the safety of the electrical systems
  • Clean and disinfect the property before tenants return

Landlords are legally responsible for repairing the damage within a reasonable timeframe. If tenants can safely remain in the property during repairs, there's no need for them to move out. However, landlords must make sure that tenants and their belongings are protected during this period.

The importance of comprehensive landlord insurance

No property is completely flood-proof, and the damage from a flood can be catastrophic. That’s why having comprehensive landlord insurance is critical. Policies like Total Landlord’s Premier policy cover the cost of any repairs required due to an insured peril, loss of rent in the event of a tenant having to move out, and for alternative accommodation if you have leaseholders in the property.

Total Landlord is also part of the Flood Re scheme, which helps keep insurance premiums manageable for properties at risk of flooding.

While you can’t prevent flooding entirely, landlords who follow these steps and make sure they have comprehensive insurance will be better equipped to protect their tenants and their investment. Read our guide, How to protect your rental property from storms, for more relevant information.
