Flood-proof your home: UK practical steps

The most effective first step for a UK home at risk is to make a personal flood plan and register for free Environment Agency flood warnings, which can arrive 12 hours in advance. After that, physical measures split into resistance (keeping water out) and recoverability (limiting damage if it gets in). The sources agree on those categories but differ on how far resistance works and who should pay. Here is the order to work through, with what each step costs in effort.

Step 1: Check your flood risk and sign up for warnings

Start by checking current flood warnings, river and sea levels, and the five-day forecast. For surface water flooding, the check-flooding service directs you to your local council. Long-term risk from rivers, the sea, surface water, reservoirs and groundwater (where data exists) needs a different service.

Sign up for free flood warnings from the Environment Agency by text, phone or email, or call Floodline on 0345 988 1188. The Flood Warning Information Service is the registration route named in the health guidance. You can also ask Floodline to send warnings to a friend or relative on your behalf.

If you live in Wales, Scotland or Northern Ireland, use the separate services rather than the England one.

Effort: low. Minutes online or one phone call.

Step 2: Write a personal flood plan

The health guidance says a personal flood plan should cover: how you will keep valuable and sentimental items safe; how you can limit how much water enters the home; insurance details; and evacuation and pet arrangements. Keep it with spare medication, important documents and contact details in a safe place.

There are template plans for individuals, for community groups and organisations (such as schools, hospitals, care homes) and for businesses. If you are in a vulnerable group, including pensionable age or living with a long-term condition or disability, register for the Priority Service Register so energy supply reinstatement gets priority support.

Effort: low to moderate. An hour to fill in, then review it.

Step 3: Prepare a grab bag

The health guidance names a grab bag containing medications and insurance documents as a simple pre-flood step. Keep it where you can reach it if you leave in a hurry. This sits alongside the flood plan, not instead of it.

Effort: low. Gather items you already have.

Step 4: Check your insurance and ask about resilient repair

Check you have adequate buildings and contents cover for flooding. Flood Re is a joint government and insurer initiative to make the flood part of household policies more affordable. If your insurer cannot offer flood cover, a new flood insurance directory set up with the Association of British Insurers, the British Insurance Brokers’ Association and Flood Re can point you to alternatives.

Ask your insurer or Flood Re whether your policy includes an amount for resilient repair, also called Build Back Better, over and above like-for-like reinstatement. FloodReady calls Flood Re’s Build Back Better initiative an important driver of property flood resilience uptake.

Renters should be encouraged by landlords to take out contents insurance, or at minimum have a flood plan covering personal possessions. If you are a landlord or housing association repairing the structure, ensure funds cover flood repair costs whether self-insuring or using the market.

Effort: low to moderate. One call to your insurer, one to Flood Re if needed.

Step 5: Install resistance measures to keep water out

Resistance measures include flood doors, barriers, gates and walls, plus self-closing air bricks and non-return valves. Some require you to deploy them during a flood, such as fitting a barrier.

Two limits matter. The health guidance states these measures are generally only effective where flood depths are under one metre, and keeping out water above that depth may affect the structural integrity of the property. It also flags that people with limited physical mobility may not be able to deploy measures such as flood gates in an emergency.

Effort: moderate to high. Professional installation and, for some measures, active deployment.

Step 6: Add recoverability measures inside

Recoverability measures are generally passive and can be retrofitted. Examples from the sources include hard wood or tiled floors at ground level, raised electrical circuits close to the ground, and a flood resilient kitchen. If water does enter, these speed recovery and reduce the financial and health burden.

The sources disagree here on how universally useful recoverability is. The health guidance says recoverability may be more effective in certain property types, and where resistance measures cannot be fitted or operated easily, its effectiveness is less clear. FloodReady treats recoverability as one of three core strands of property flood resilience alongside resistance and reduction.

Effort: moderate. Best done during planned renovation.

Step 7: Reduce runoff at your property

FloodReady’s third strand is reduction: lowering water runoff by retaining and improving drainage at property level. Named methods include permeable surfaces, rain gardens and rainwater harvesting. The health guidance frames these as sustainable drainage systems (SuDS), giving green roofs and rain gardens as small-scale examples, and notes co-benefits such as improved mental wellbeing, air and water quality, and biodiversity.

Effort: low to moderate. Start with removing paving for natural drainage.

Step 8: Know your local support and responsibilities

Find out what is available locally before a flood: flood action groups (volunteers working with councils and agencies), community flood wardens who monitor a specific area and tell residents when flooding is likely, and community hubs providing food, clothing, shelter and advice during a flood. You can find them on social media, your local council’s website, or by contacting the National Flood Forum.

In England, lead local flood authorities manage ground and surface water flood risk locally and can tell you who is responsible in your area. If your property is next to a river, culvert, brook or mill stream you must maintain river beds and banks, not obstruct water flow, not pollute the water, and protect wildlife; contact the Environment Agency with questions. Next to a canal, contact the Canal and River Trust to check maintenance responsibility. Citizens Advice can help if your energy supply is affected.

Effort: low. A few web searches and a call.

What the sources disagree about

How far resistance works: the health guidance sets a one metre depth limit and warns about structural integrity above it; FloodReady promotes resistance as a core measure without stating that limit in its summary.

Universal benefit of recoverability: the health guidance says effectiveness is less clear in some property types and where resistance measures cannot be fitted or operated; FloodReady presents recoverability as a standard strand for all.

Who is responsible for scaling it up: FloodReady’s year 10 ambition is for property flood resilience to be as common as insulation, fire safety and security, integrated into planning and building regulations. The health guidance focuses on individual and household action plus local authority targeting. Until that integration happens, the practical steps above remain the householder’s route.

Market size and uptake: FloodReady cites a 2023 Flood Re report putting the sector at £20 to £25 million per year, small within the UK, and says uptake remains low. The National Flood Forum’s figures show the scale of the audience: 6.3 million properties in England at risk and over 1,000 people a year using its helpline.

Frequently asked questions

How much warning will I get?

The health guidance says people who have prepared and receive warnings get them 12 hours in advance. The check-flooding service shows risk over the next 5 days.

What is the cost in effort?

Lowest effort: checking risk, signing up for warnings, writing a plan, preparing a grab bag, reviewing insurance. Moderate: recoverability measures during renovation. Highest: professionally installed resistance measures, plus learning to deploy them.

What if I rent?

The health guidance says landlords should encourage tenants to take out contents insurance or at minimum have a personal flood plan covering personal possessions.

Where can I get independent advice on products?

The health guidance names the National Flood Forum, including its Blue Pages guide, and the Flood Protection Association as organisations that help householders learn about flood defence technology.
