Preparing for flooding in the UK

Check your local flood risk and learn how warnings work before water threatens your area. Keep important contacts, medicines, documents and a small leaving bag ready, and follow instructions from the official flood service for your nation. If water is rising or you are told to leave, put personal safety first and never walk or drive through floodwater.

Prepare before a flood warning

Flood preparation begins with knowing which official service covers your address. A postcode tool can point you to government and environmental agency information, but it does not replace local advice or tell you what is happening at a particular property. Check the service directly, note how it sends alerts and make sure the contact details are current. If you are renting, ask the landlord or managing agent whether the building has a flood plan and where shared equipment is stored.

Make a household plan that says who will contact whom, where to meet and how to leave if routes change. Include children, older relatives, disabled household members, pets and anyone who may need help with transport. Choose a contact outside the immediate area in case local phone networks are busy. Keep a paper copy of key numbers because a phone may run out of charge or become wet.

Put essential items together in a place that is easy to reach. A leaving bag might hold medicines, a phone charger, a small power bank, spare clothing, water, familiar snacks, keys and copies of important contacts. Store irreplaceable documents and devices above areas that could flood. Keep originals secure and consider a protected digital copy, but do not put sensitive information in a bag that may be left unattended.

Check your home insurance documents and record the insurer's claim contact. Photograph rooms and belongings for your own records when it is safe and appropriate. Ask the insurer what it expects if a flood risk increases and whether temporary protection measures are covered. If you own the property, check whether any flood adaptation work needs planning or building approval. Renters should ask the landlord before making physical changes.

Move essential items upstairs or to a higher shelf if official advice says flooding is possible and there is time to do so safely. Do not enter floodwater to move property. Keep the route out of the building clear, and make sure everyone knows where a torch and the household contact list are kept. If you need specialist support to move, do not wait until water is at the door to contact the people who can help.

Flood water may contain sewage, chemicals, debris and hidden hazards. Do not touch it if you can avoid doing so. Keep children and animals away from flooded areas. If water enters a property, follow advice from the local authority, utility providers and emergency services about electricity, gas, drinking water and re-entry. Never switch electrical equipment on if it has been wet or if there is standing water around it.

Check warnings and local flood risk

In England, the government provides a live flood service to check current warnings and a separate service for long-term flood risk. You can also sign up for flood warnings where the service covers your area. These pages serve different purposes, so use the live service for current conditions and the long-term service when making a home or insurance decision. Neither replaces an instruction from emergency services during an incident.

Understand the wording used by the service that covers your area. An alert, warning or severe warning may describe different levels of risk and action. Do not assume that labels are identical across all UK nations. Read the official explanation for your location and make a note of what action it recommends. If a warning arrives, check its location and time, share it with household members and follow its instructions.

Set up more than one way to receive information. Sign up for relevant warnings, keep local authority and emergency service pages bookmarked, and make sure your phone can receive government emergency alerts. A phone alert system is not a replacement for flood warnings, and a lack of an alert does not prove that an area is safe. If you can hear a warning but cannot confirm its details, use official channels or call the appropriate service.

Check routes as well as the home address. Roads, paths, bridges and public transport can be affected before a property floods. Do not drive through water or around a road closure. Water depth is difficult to judge and road surfaces can be damaged underneath. If travel is necessary, use an official route and follow local closures. Delay a journey if conditions make it unsafe.

Local terrain can make flood conditions different from one street to another. Hills, rivers, drainage systems, coastal areas and previous land use all matter, but a general map cannot show every local factor. Ask the council or environmental service about local plans, warning coverage and community support. If you have recently moved, find out where water could collect and which routes remain open in poor weather.

Protect people, pets and property

Put personal safety ahead of belongings. Follow any evacuation instruction and leave early enough to avoid walking through floodwater. Do not go back into a flooded building to retrieve something. If you cannot leave safely or someone is in immediate danger, call 999. Tell emergency services if anyone is unable to move without assistance or relies on medical equipment.

Only use flood barriers, door covers or sandbags where they are suitable for the property and the expected conditions. Check the supplier instructions and official advice. A barrier can redirect water toward another entrance or neighbour, and it may not stop water entering through drains, walls or another opening. Ask the council or an appropriate flood professional about local measures rather than treating a product description as a guarantee.

Before a flood, learn where the electricity consumer unit, gas supply and water stop tap are located. Ask the utility or a qualified professional how to isolate a service safely. Do not enter a flooded area to operate a switch or valve. If water reaches electrical equipment or gas appliances, leave and contact the appropriate provider or emergency service. Do not reconnect equipment until it has been checked by a qualified person.

Prepare for cleaning and recovery only after the area is declared safe. Floodwater may leave contamination on floors, furniture and food packaging. Wear suitable protection and follow local health guidance. Discard food that has been in contact with floodwater, and seek official advice before using water from a tap if a notice has been issued. Keep children and pets away from the clean-up area.

People who need regular care should agree a flood plan with family, carers and service providers. Keep an up-to-date medicine list, equipment details and supplier contacts in a waterproof place. Ask the clinician or supplier what to do if a device is damaged or if electricity and transport are disrupted. The Priority Services Register may help utilities identify support needs, but it is not an evacuation plan and does not guarantee a particular response.

Pets need a realistic transport and accommodation plan. Keep leads, carriers, medication and familiar food accessible. Ask a vet where records can be obtained and what to do for an animal with a health condition. Contact accommodation providers in advance because not every temporary location accepts animals. Do not leave a pet tied outside or in a flooded room while people leave.

If you may need to leave home

Make a leaving plan for each person, not just a list of supplies. Decide who will collect children, who will carry the household information and how a pet will travel. Choose a meeting point away from the immediate area and a second contact method if mobile service fails. Keep fuel and travel arrangements ordinary and legal. Do not wait until a route is cut off to start the journey.

Take essential medicines and devices if they are safe to carry, along with instructions and charging equipment. If you rely on refrigerated medicine, contact a pharmacist or clinician about safe transport and storage. If someone uses powered medical equipment, contact the supplier or care team before a flood if possible. Follow their advice and emergency service instructions rather than improvising a power source.

Protect important information without delaying departure. Keep insurance numbers, identification and emergency contacts in a waterproof pouch or stored securely online. Avoid carrying more valuables than you can manage safely. Tell a trusted person where you are going if you can. If a council or emergency service provides a reception point, use its current directions and check whether it can accommodate your household's needs.

When returning after a flood, wait for official advice that the property and route are safe. Structural damage, contaminated water and electrical faults may not be obvious. Contact the insurer and utility companies before starting repairs. Take photographs if it is safe, keep receipts and make a note of calls. Do not use damaged electrical appliances or enter rooms where the ceiling, walls or floor may be unstable.

Use the flood service for your nation

In England, GOV.UK links to flood preparation, warnings and current conditions. The Environment Agency's live service can show warnings and local information. Use the long-term risk service when assessing property exposure, and contact your council for local flood plans and recovery information.

In Wales, Natural Resources Wales publishes flood information and warnings. Check its current service for local coverage and follow its instructions. Local authorities can provide information on community arrangements and recovery. Welsh services and warning language may differ from the English service, so use the Wales-specific pages.

In Scotland, SEPA provides flood information and Floodline registration. Check the service for local warnings and sign-up arrangements, and use Scottish Government or council advice for wider response information. A postcode result is only a starting point when planning a property or route.

In Northern Ireland, nidirect provides flooding guidance and points to local information. Check the service for current advice and local arrangements. Do not assume a GB warning service covers a Northern Ireland address. During a serious incident, follow police, fire and rescue, ambulance and local government instructions.

Flood guides and tools

The flood preparation guide turns the main planning steps into a household checklist, including warning sign-up, property information and safe preparation. For the wording of alerts and warnings, read the guide to flood alert versus flood warning. It explains why readers should check the service for their own nation and location rather than rely on a label in isolation.

The flood kit list focuses on what may help if a household needs to leave or cope with disrupted services. It is a starting point for personal decisions, not a fixed pack for every household. If a flood could mean leaving quickly, the UK grab bag guide explains how to keep a small set of useful items accessible without carrying unnecessary weight.

For comparing household supplies with a prepared box, the ready-made kit versus DIY guide shows how to review contents and identify what a household still needs. Flood preparation often has more specific requirements than a general emergency kit, so check local advice before relying on barriers, protective equipment or any item described as flood protection.

Use the local risk links tool to find official services based on a postcode area. The tool does not hold flood data or make a risk assessment. The grab bag builder can help organise a leaving list on your own device. Check the list against each person's needs and current directions from official services.
