Does Landlord Insurance Cover Flood Damage?
Yes, flood is a named peril on almost every landlord buildings policy, so the structure, the fitted kitchen and the electrics are all insured. What changes with risk is the excess and the price, not usually the cover itself.
The part landlords get wrong is Flood Re. The scheme that keeps flood premiums affordable for households mostly does not reach a tenanted let, which makes the terms on your landlord buildings policy the only protection you have.
A flooded ground floor takes months to dry, not weeks. Knowing what your landlord policy covers before the water arrives is what decides whether that period costs you an excess or a year of rent.
Flood is a named peril on almost every landlord buildings policy, so the structure, the fitted kitchen and the electrics are insured; what moves with risk is the excess and the price rather than the cover itself. Flood Re keeps household premiums affordable but mostly does not reach a tenanted let, which leaves your buildings wording as the protection you actually have.

What does flood cover pay for on a rental property?
Flood cover pays to return the building to the condition it was in before the water came in. That means structure, services, fitted items, professional drying and the removal of everything the flood ruined.
What the buildings section puts right
- Structure: walls, floors, joists, ceilings and foundations soaked or undermined by floodwater.
- Services: rewiring, replumbing, and a new boiler where the old one sat below the water line.
- Fitted items: the kitchen, the bathroom suite and built-in units, which are almost never salvageable once chipboard swells.
- Drying: commercial dehumidifiers and heat, typically running for six to twelve weeks on a ground floor.
- Clearance: silt, contaminated carpet, plasterboard and the skips to take it all away.
The bills are large because everything below a metre has to come out. According to the ABI, insurers paid £1.2 billion last year for weather damage to homes and businesses, with 46% of it falling in the second half of the year.
What landlord contents cover adds
Your contents cover picks up the white goods, carpets, curtains and furniture you supplied. On a furnished let that is often £8,000 to £15,000 of replacements on its own.
Your tenant’s own possessions are not yours to insure. Tell them at the start of the tenancy that a flood will leave their sofa and their clothes uninsured unless they arrange contents cover themselves.
What the flood section will not touch
Gardens, fences, gates, sheds and detached outbuildings are excluded on most policies unless they are listed on the schedule. Boundary walls washed out by a swollen watercourse are a common uninsured cost.
Mould that appears months later because the property was rushed back into use is treated as a maintenance failure, not flood damage. It is also a hazard you are answerable for under the government’s damp and mould guidance for rented housing.
Why does flood re not help most landlords?
Because Flood Re only backs household policies held by individuals who live in the property for at least part of the time, or where the property is empty. A house let to tenants while you live somewhere else fails that test.
The occupancy rule that rules out tenanted lets
The second of the eight criteria published by Flood Re says the holder of the policy, or their immediate family, must live in the property for some or all of the time, or the property must be unoccupied. There is no version of a normal assured tenancy that satisfies it.
The first criterion is just as restrictive: the contract has to be held in the name of, or on trust for, one or more individuals. That is a household insurance policy, not a landlord product, which is why insurers cannot simply cede your let to the scheme when you ask.
Where company-owned and portfolio property stands
Company houses and flats are excluded outright, so a property held in a limited company or an SPV can never reach the scheme however it is let. That catches a large share of modern buy-to-let ownership.
Flood Re also excludes blocks of more than three residential flats, which leaves a block of flats policy exposed to open-market flood pricing. Freeholders and leaseholders insuring several properties as a portfolio for commercial gain are excluded on the same basis.
Which landlord-owned property does qualify
There are real exceptions. A holiday home or short-let property you use yourself is on the eligible list, and so is a property standing unoccupied between tenancies.
| Property or arrangement | Flood Re position on buildings cover |
| Home you live in, insured in your own name | Eligible if built before 1 January 2009, council tax bands A to H |
| Holiday home or second home you use yourself | Eligible |
| Let property standing empty between tenancies | Eligible while unoccupied |
| Let property with tenants, you living elsewhere | Fails the occupancy criterion |
| Property owned by a limited company or SPV | Excluded, the policy must be in an individual’s name |
| Block of more than three residential flats | Excluded from buildings cover |
| Portfolio insured by a freeholder for commercial gain | Excluded |
| Your tenant’s own contents policy | Eligible in its own right |
Where the scheme does apply, it caps what the insurer pays into it at between £147 and £1,077 for buildings depending on council tax band for 2026/27, with a fixed £250 flood excess. Flood Re is funded by a levy on insurers and is due to run until 2039.
How do you check a property’s flood risk before you insure it?
Run the postcode through the Environment Agency’s free service before you buy the property, not before you buy the policy. Risk data is the single largest input into a flood-exposed quote.
The environment agency check
The Environment Agency’s check for flooding service covers England, with separate services run by Natural Resources Wales, SEPA in Scotland and the Department for Infrastructure in Northern Ireland.
It shows live warnings and alerts, river and sea levels, and links through to a long-term risk check for rivers, the sea, surface water and groundwater. Sign up for the free alerts and add your letting agent‘s number as well as your own.
What your insurer sees that the free check does not
Underwriters buy commercial flood models that work to individual address level and ground height, not the postcode band you see. That is why two houses on the same street can be quoted £280 and £1,400 for the same cover.
They also hold claims history against the address, which follows the property rather than the owner. A flood claim made by the previous landlord in 2019 will still be sitting there when you buy in 2026.
What does flood cover cost on a high-risk let?
Most landlords pay nothing extra because most properties are low risk. Once a property is in a flood zone the cost usually arrives as a much larger excess rather than an outright refusal.
Excesses and loadings by risk band
| Flood risk band | What most insurers do | Typical flood excess | Premium effect |
| Very low or low (most UK lets) | Flood included as a standard peril | £250 to £500 | No flood loading |
| Medium (surface water, nearby watercourse) | Flood included, excess raised | £1,000 to £2,500 | A modest loading |
| High (flood zone, limited defences) | Referred to an underwriter, terms restricted | £5,000 or more | The biggest single line on the premium |
| Previous flood claim at the address | Mainstream insurers usually decline | £10,000 or more | Specialist market pricing only |
| Flood excluded by endorsement | Buildings cover written without flood | Not applicable | Cheaper, but you carry the whole risk |
A £5,000 excess is not a technicality on a flood claim, it is the first £5,000 of a £40,000 strip-out that you fund yourself. Check the flood excess on the schedule every renewal, because insurers raise it quietly.
Why the excess matters more than the premium
Landlords tend to shop on annual price and ignore the flood excess line. On a flood-exposed property the excess is the number that decides whether you can afford to claim at all.
Paying £150 more a year to bring a £10,000 excess down to £2,500 is the better trade in almost every case. Ask the broker to quote both and compare them side by side.
How is flood damage different from escape of water?
Flood is water arriving from outside the building. Escape of water is water that was already inside it, and the two sit in separate sections of the policy with separate excesses.
Two perils, two excesses
| Point of difference | Flood | Escape of water |
| Where the water comes from | Rivers, the sea, surface water, groundwater | Burst pipes, failed tanks, leaking washing machines |
| Typical trigger | A storm, a blocked culvert, a river over its banks | A frozen pipe, a perished seal, a failed hose |
| Typical excess on a let | £250 to £10,000 depending on risk band | £250 to £500 on most policies |
| Contamination | Sewage and silt, so everything porous is condemned | Clean water, so more can usually be dried and saved |
| Drying time | Six to twelve weeks on a ground floor | Two to six weeks for a single room |
| Effect on renewal | Can make the address hard to place | Priced in, rarely a decline |
Why the wording decides your claim
A drain backing up inside the property after heavy rain can be argued either way, and the answer changes your excess by thousands. Read the definition of flood in your wording rather than assuming.
Some policies still exclude rising groundwater while covering river and surface water flooding. If your property sits on chalk or a high water table, that exclusion is the one to hunt for.
What happens to the tenancy while the property dries out?
The tenancy survives the flood. Your tenant keeps their rights, and unless the agreement says otherwise you keep charging rent for a property nobody can live in, which is why loss of rent cover matters here.
The tenancy does not end because the property floods
Since 1 May 2026 every tenancy is a periodic assured tenancy under the Renters’ Rights Act, and there is no Section 21 route to end one because the building is wrecked. Redevelopment and demolition grounds exist, but they are narrow and slow.
In practice most landlords and tenants agree a rent suspension or a surrender while the work runs. Put whatever you agree in writing on the day, because a verbal arrangement made in a crisis gets disputed later.
What loss of rent and alternative accommodation cover pay
Loss of rent sits inside let property insurance and pays the rent you lose while an insured event makes the property uninhabitable. Limits are usually 20% to 30% of the buildings sum insured, or a fixed 12 to 24 months.
Alternative accommodation cover rehouses the tenant, which is what stops a flood becoming a possession dispute. Neither of these is rent guarantee insurance, which responds to arrears rather than to damage.
What can you do if no insurer will quote?
Stop using price comparison sites and go to a specialist broker. Flood-declined property is a placed risk, not a shopped one, and the markets that write it rarely appear on aggregators.
Specialist and parametric markets
Brokers who write non-standard property risks have access to Lloyd’s syndicates and MGAs that will price a flooded address individually. BIBA also runs a free Find Insurance service on 0370 950 1790 with a dedicated flood directory.
Parametric flood cover is the fallback when nobody will indemnify the building. A sensor at the property triggers a fixed payout at an agreed water depth, and settlements have been paid within 27 hours of a named storm.
The trade-off is that a parametric payout is a set sum, not the cost of the repair. It works best alongside buildings cover written with a flood exclusion.
Resilience work that reopens the market
- Flood doors and demountable barriers at every ground-floor opening, certified to BSI Kitemark where possible.
- Non-return valves on foul and surface water drains to stop sewage backing up.
- Sockets, switches and the consumer unit raised above 1.2 metres.
- Tiled or sealed concrete floors and solid-wall kitchen units instead of chipboard carcasses.
- A survey report and photographs of the completed work, which is what an underwriter will actually read.
Where a policy is backed by Flood Re, its Build Back Better scheme reimburses up to £10,000 of resilient repairs on top of the flood claim itself. Individual insurers can set a lower limit, so confirm the figure before you commission the work.
After severe flooding the government has repeatedly activated property flood resilience grants through local councils. Ask your council whether let property in your area qualifies, because the terms change with each activation.
Frequently Asked Questions (FAQs)
On almost every landlord buildings policy, yes. Flood sits alongside fire, storm and escape of water as a named peril, though the excess can be far higher.
Rarely. Flood Re requires the policyholder or their immediate family to live in the property for at least part of the time, or the property to be unoccupied.
No. Company houses and flats are excluded, and the insurance contract has to be held in the name of one or more individuals.
Yes. A tenant’s contents policy in a rented home is eligible in its own right, which is worth telling them when they move in.
You do. The excess belongs to the policyholder, and you cannot pass it to a tenant unless they caused the damage.
Only if you have loss of rent cover and the damage was an insured event. Without it you are relying on the tenant continuing to pay for a home they cannot use.
Yes, and the claim stays against the address rather than against you. Expect a higher flood excess at the next renewal even where the premium holds.
You do not need to make a claim, but tell them anyway. Non-disclosure of a known flood event is one of the easier ways to lose a later claim.
No, that is escape of water, a separate peril with its own excess. The distinction matters because flood excesses on a let can be twenty times higher.
Not always. Several policies cover river and surface water flooding while excluding rising groundwater, so check the definition in your wording.
Usually yes, through a specialist broker rather than a comparison site. Expect a large flood excess, and resilience work with photographic evidence will improve the terms.
