Flooding
Overview
Flooding is a natural event. No drainage or flood protection system can ensure you won't be affected but the following pages provide guidance for homeowners and businesses on how to prepare and what to do before, during, and after flooding. They also signpost to data on your flood risk and services for flooding alerts, suggestions for flood protection products, and information on storm grants and support.
If you need to report flooding, see our page: Report a problem with flooding or drainage.

What to do during a flood
For information on what to do during a flood, see:
What to do before or during a flood (gov.uk) (opens new window)
Immediate actions to take if you're about to be flooded:
- turn off your gas, electricity and water supplies, if it's safe to do so - do not touch an electrical switch if you're standing in water
- move your family, vehicles, pets and important items to safety, for example upstairs or to higher ground
- if you have them, use flood protection products, for example flood barriers or air brick covers
- follow advice from your local council or the emergency services - you may be asked to evacuate
Where they can, the council, emergency services and Environment Agency will help, but if the flooding is over a large area, they may not be able to respond to every call.
What to do after a flood
Follow the government advice for what to do after a flood, including guidance for those who rent their property.
What to do after a flood (gov.uk) (opens new window)
Remember, safety is key:
- do not turn on your water, gas or electricity - get your utilities company or a qualified engineer to check they are safe first
- do not drink your tap water if you notice a change in the colour, taste or smell - contact your water company if this happens
- do not eat any food that has been contaminated by flood water
Financial support
There may be financial support from the government after a storm or a flood. Check our Storm grants and support pages for details.
Flooding advice for businesses
If your business is in a flood risk area, find out what you can do to prepare.
If your business is at risk of flooding (see Flood risk, maps and warnings) there are measures you can take to prepare and reduce the impact.
Preparing your business for flooding
Having a plan before flooding strikes will make your business more resilient and will help you to get back to business as usual in the shortest possible time. The government provides advice on how to prepare, which includes a checklist for you to create your plan.
Prepare your business for flooding (gov.uk) (opens new window)
There is also specific guidance for campsites and caravan parks: Managing flood risk for campsite and caravan park owners (gov.uk) (opens new window).
Actions you can take now
- make a list of the organisations and individuals you deal with, including their contact details, keep a copy in a safe place off the premises
- back up databases or other computer applications regularly, keep a copy in a safe place off the premises
- consider whether you could operate from another location, away from flood risk
- make a list of your machinery and contents so that replacements can be ordered quickly
If flooding hits, keep receipts of any expenditure, and a note of the actions you took, to help with insurance claims.
Get business insurance
You should look into:
- buildings insurance - to cover flood damage to buildings
- contents insurance - to cover damage to items, for example stock
- business interruption insurance - to cover running costs or losses, for example salaries or loss of profit
Small businesses can get advice from the: National Flood Forum (nationalfloodforum.org.uk) (opens new window).
If your insurer asks for evidence of your flood risk, contact the Environment Agency. You'll get a letter within 20 days. It's free for individuals and businesses.

Business Continuity
Local authorities are required to provide guidance to local businesses on emergency planning and how to prepare. See our Planning for an emergency: Businesses pages for advice.
If your business has been flooded
Follow the relevant information on the government's pages:
What to do after a flood (gov.uk) (opens new window)
And remember, safety first:
- grounds and buildings should be checked by qualified professionals before you return - a building may look safe, but it could have suffered structural damage
- power and gas supplies should be checked by qualified professionals before switching them on
Check with your insurance company before you start to repair damage, or replace goods - you may receive an interim payment to get your business going again as quickly as possible.
Report a problem
To report flooding, and find out who is responsible for what when it comes to flooding, see our page:
Flood protection products and sandbags
As a property owner it is your responsibility to protect your property from flooding, see our Flooding advice for homeowners or Flooding advice for businesses pages on how to prepare your home or your business for flooding.
Flood protection products
Of the things you can do, flood defence products like flood gates, non-return valves, air brick covers and toilet bungs, are a good way to protect yourself. Information and advice about these products, where to buy them, and how to fit them, can be found on the National Flood Forum's Blue Pages website:
Blue Pages: Independent flood directory (opens new window)
Sandbags: traditional and modern alternatives
Sandbags have traditionally been used in flood defence to block doorways and drains, weigh-down manhole covers and garden furniture, and to block sink, toilet and bath drains to prevent water backing up. However, they are relatively ineffective when compared to modern, purpose-designed flood protection products, which we strongly encourage people to use.
Modern alternatives to traditional sandbags are lightweight and can soak up water. They are easier to store and, although they can't be used twice, some are biodegradable. See: Sandbags - Traditional and Alternatives (bluepages.org.uk) (opens new window) for details.
You need to make your own arrangements to buy sandbags. We have a limited supply, requests for them during an emergency are considered on a case by case basis and prioritised by level of need or vulnerability. See our Flood sandbag policy (PDF, 16 KB)(opens new window).
Supplies of sandbags and sand
Supplies of sandbags and sand may be available from your local builders' merchants.
Flood guidance for towns and parishes
On this page we signpost you to guidance and information to help you create your community flood plan. We also provide information on rights, responsibilities, and legislation regarding flooding and drainage, to help you respond to queries from your community.
Create your plan
You can't stop flooding, but understanding the risk to your community and working together to prepare a plan will help you respond and recover as quickly as possible. Your plan should complement any response the emergency services and the local authority offer. Always follow the advice of the emergency services, and put safety first.
The government has provided guidance to help you create your plan, including advice on what to do before, during, and after a flood:
Community flood plan (gov.uk) (opens new window)
Keep your plan simple and easy to follow, and let your residents know you have one. Remember that building relationships and ways of communicating can be as important as the plan itself.
Further resources, hints and tips for your plan
Flood risk, and where to get your data
The following resources will help you understand your community's risk of flooding, and the source of flooding:
- Flood risk, maps and warnings - find out if you are at risk of flooding, check the flooding forecast, and sign up for warnings
- Environment Agency: Statutory Main River Map (arcgis.com) (opens new window) - check for risk of flooding from your rivers
- Drainage@wiltshire.gov.uk - request groundwater flood maps, and an AO map of your community

Flood alerts and warnings: what they are and what to do (gov.uk) (opens new window) - understand the three levels of warnings, and what to do for each
Flood equipment, where to get it, and what to consider if you have any
See our Flood protection products and sandbags page for information on flood protection products and where you can buy them. Share this information with your residents.
The Parish Emergency Assistance Scheme (PEAS) currently offers a selection of equipment free to towns and parishes who have a flood plan. Contact drainage@wiltshire.gov.uk for PEAS.
Watercourses, ditches and gullies - rules and responsibilities
Landowners must maintain any watercourses, ditches or gullies on their land. Roadside ditches are the responsibility of the adjacent landowner.
For guidance on what constitutes a watercourse, and the rules and responsibilities for managing flood risk, see:
Owning a watercourse (gov.uk) (opens new window)
See the 'Town and parish ditch project' section on our Operational flood working groups page for more details, and tools and tips on how to approach landowners.
Sharing information - using ETHANE
The ETHANE model is a reporting framework for flood incidents, providing a structure for responders to share incident information. For more information, see: M/ETHANE (jesip.org.uk) (opens new window).
Ways of communicating
The use of social media in emergencies can play a vital role in communicating, and enable you to follow organisations that put out emergency information. Sign-up to information channels, for example:
- Environment Agency (facebook.com) (opens new window)
- The Flood Hub (facebook.com) (opens new window)
- @metoffice (x.com) (opens new window)
Operational flood working groups
Wiltshire council has set up two Operational Flood Working Groups, one in the north, and the other in the south of the county. They meet bi-monthly, and are normally hosted in different town and parish councils within each area.
Currently the meetings are held virtually. Town and parish councils wishing to attend these meetings should contact drainage@wiltshire.gov.uk (opens new window) for details on how to join.
Storm grants and support
The government decides when support is made available for flooding; which areas receive it and guidance around eligibility. We administrate access to that support for individuals and businesses, and can add further eligibility criteria.
Storm Bert (November 2024)
Unfortunately, the government has now confirmed that there will be no grant funding available to residents or businesses following the Storm Bert floods. See our press release for more information: Wiltshire Council shares disappointment at lack of Government support for those affected by flooding.
Storm Babet (October 2023) and Storm Henk (January 2024)
Homes or business significantly impacted by flooding from Storm Babet (Oct 2023) or Storm Henk (Jan 2024) were able to apply for Government grant funding. There were different types of support depending on the damage and type of property affected.
Community Recovery Grant: Storm Henk, closed
Grants of up to £500 were made available to help affected severely affected flooding households with their immediate recovery.
Business Recovery Grant: Storm Henk, closed
Grants of up to £2,500 per small and medium-sized enterprise (SME) were made available to support businesses that suffered severe impacts from the floods.

Section 19 Reports
Part of our duty, under the Flood and Water Management Act 2010, is to investigate significant flood incidents and produce what are called 'Section 19 reports'.
The purpose of these reports is to establish what caused the flooding, assess how authorities responded, and determine what actions are needed to prevent future floods. This ensures accountability, transparency, and improved flood management for the community.
