Preventing and Managing Your Flooding Risk

Flooding is a significant risk for property owners in the UK. Over five million homes and businesses are at risk - about one in six properties.


These events can cause severe damage to buildings and belongings, often triggered by natural weather events or preventable home maintenance issues.


As the UK climate continues to change, the risk of flooding is growing.


Homeowners must protect their property and reduce damage when flooding occurs.


By preparing, you can minimise the impact on your home and possessions.


What causes flooding in the home?


The most common causes of floods are large-scale geographical factors beyond human control, resulting from excess low-lying water in specific areas. Some common causes include:



  • Extreme weather events

  • Heavy or prolonged rainfall

  • Melting snow and ice

  • Dam failures

  • Overuse of impermeable materials in construction

  • Coastal flooding

  • Steep slopes and saturated soil


These factors can cause water to enter your property through doors, windows, or drains.


Flooding can even happen on dry days due to plumbing problems, such as bursts or clogged pipes.


Preventing against weather-related flooding


Flooding associated with weather phenomena may seem difficult for those living in high-risk areas, as such incidents are typically caused by factors beyond an individual homeowner’s control.


However, steps can still be taken to reduce the danger level as much as possible.


How to prevent flood damage caused by the weather


Monitor local conditions and flood risks


No matter where you live, being aware of flood risks can sometimes mean distinguishing between a protected and a damaged property.


Those living in high-risk areas will often be aware of this, as their house and contents insurance costs are likely higher.


However, you can use the flood risk maps if you need clarification and want to check.


Check out these flood maps.


They examine risks brought about by rivers, the sea, surface water, and reservoirs and can provide valuable information about local risk factors.


For more details, contact the Environment Agency, which can provide information about the history of flooding around a property.


You can sign up for flood warnings if you live in England or Wales. You never know when some advanced knowledge could help you save what’s important!

These alerts can be delivered via email, text, or phone call and are offered as a free service.


The Met Office is another helpful resource. Its website and app provide five-day weather forecasts, warnings, and coping advice.


DEFRA also includes information about flooding, while the National Highways weather watch offers valuable guidance for journey planning.


Last but not least, you can also find flood alert news on our social media accounts, and we regularly share pertinent information directly from the above agencies.


Take precautionary measures


These simple steps can reduce the damage caused by flooding:



  • Install door guards to block water at entry points.

  • Use ventilation brick covers and damp-proof barriers.

  • Consider sandbags or flood-resistant alternatives like FloodSax.

  • Landscape your garden to direct water away from your home.

  • Install non-return valves on drains to prevent backflow.


For most private properties, a full-scale flood plan isn’t usually necessary in the same way as it would be for a business with a large staff, but keeping a supply of door barriers and sandbags – or similar products, such as FloodSax – can nevertheless be a wise precaution for protecting entranceways. This is especially advisable for riverside property owners, who are generally responsible for managing their flood risks.


Insurance is also a big part of the preparation process, so homeowners must check what their policy covers in the event of flooding, especially if they live in a flood-risk area. This may mean clarifying any ambiguities with policy providers, which is more straightforward to do before the event than afterwards.


Preventing Plumbing-Related Flooding


Flooding caused by plumbing issues is often avoidable with regular maintenance. Common plumbing issues include burst and frozen pipes, which can cause significant damage. To prevent these:



  • Insulate pipes to protect them from freezing.

  • Drain outdoor water-based appliances in cold weather.

  • Regularly repair leaks and clean drains to prevent blockages.


How to prevent plumbing-related flooding


Avoid burst and frozen pipes


Burst pipes are one of the most common culprits when it comes to causing home floods, typically when water in the pipes freezes and expands, creating pressure from the inside and causing them to break.


Mitigating this risk means taking action to prepare pipes and drains for the onset of colder weather, with advisable precautions including:



  • insulating pipes, drains and cisterns

  • draining pipes connecting to outdoor water-based appliances

  • repairing leaks as quickly as possible

  • keeping heating on a low level during the winter months

  • plugging draughts beneath doors and between brickwork to prevent the house from getting too cold

  • removing leaves, mud or other detritus from drain gates

  • installing a non-freeze plastic drain protector


Read our guide on preparing pipes and drains in winter for more information about organising and maintaining them during the winter months.


Avoid blocked and clogged pipes


Blockages in pipes and plumbing are also common causes of flooding, despite this issue being much easier to prevent than weather problems or frozen pipes.


Generally, clogging issues are caused by many common substances and products – which we at Lanes refer to as the ‘Big Offenders’ – tipped into the sink or flushed down toilets.


The Big Offenders are:



  • fats, oils and grease

  • wet wipes

  • nappies and pads

  • sanitary products

  • tampons, applicators and wrappers

  • condoms

  • razor blades

  • bandages and plasters

  • dental floss

  • medicines and syringes

  • cotton buds

  • Hair


Dealing with Blocked Drains


Clogged drains are a significant cause of home flooding, often caused by grease, wet wipes, or sanitary products flushed down the toilet or poured down the sink.


Blocked drains may show signs like slow drainage, foul smells, or gurgling noises.


Prevent blockages by being mindful of what goes down your drains.


Regularly maintain your drainage system to identify issues before they become significant problems.


What to Do When Flooding Happens


Despite all precautions, flooding can still occur. If flooding strikes, take immediate action to reduce damage:



  1. Turn off utilities at the main valve.

  2. Protect entryways with sandbags or flood barriers.

  3. Move electrical items and valuables to higher ground.

  4. Use bricks or pallets to elevate furniture and other items.


After protecting your property, contact local authorities for help. If flooding is severe, your local fire and rescue service may be able to pump out the water.
