Flood Certificates Are Coming: What Sellers Need to Know

By Lisa Hayes · 18 October 2026

The government and Flood Re are about to pilot "Flood Performance Certificates" in England: an EPC-style rating that tells a buyer, a lender and an insurer how exposed a home is to flooding and how well it would cope. Pilots start before the end of 2026 in flood-prone areas, with more through 2027 and beyond. If you own a home, it is the first real sign that flood risk could become a line on the paperwork when you sell, in the same way your energy rating already is.

Nobody is forcing you to do anything today. But if you are thinking of selling in the next couple of years, this is worth ten minutes of your attention, because it changes what buyers will be able to see about your house before they ever book a viewing.

What has actually been announced?

The announcement came from the Floods Minister, Emma Hardy, and Flood Re, the insurer-funded scheme that keeps home insurance affordable for homes at higher flood risk. Flood Re is the body running the pilots. Its chief executive, Perry Thomas, described the idea this way: "Flood Performance Certificates are about turning awareness into action," as reported by Insurance Business UK.

The certificate is modelled on the Energy Performance Certificate, the A-to-G document you already know from every property listing. But the pilots will test something a bit more nuanced than a single letter. The proposed "Flood Performance Rating" breaks a property's risk into three pieces:

• Exposure: how likely the location is to flood, drawn from the government's existing "Check your long term flood risk" service, which covers rivers and surface water.
• Characteristics: how the building itself is constructed.
• Resistance: how well it keeps water out, or limits the damage, when flooding happens.

Resilience measures should move the rating. The reporting mentions flood barriers, self-closing air bricks, water-resistant flooring and flood-resilient kitchens. The certificate should also show you where the house could be made tougher, which is the bit I find most interesting, because a rating that only tells you how bad things are is a label. One that tells you what to fix is a to-do list.

What is still unknown?

Quite a lot, and it matters. The coverage I have read does not name the pilot areas. It does not say how many homes will be included, what the certificates will cost, or who pays. And it does not say outright whether FPCs will be voluntary or eventually compulsory. Everything points to voluntary for now, since these are pilots, but that is an inference rather than a promise.

That gap is where the spin lives. Headlines such as "EPC-style flood certificates could change how homes are sold" are fair enough as a forecast. They are not a description of something that exists. As of today, there is no flood certificate on your house, no buyer is asking for one, and no mortgage lender has announced it will require one. Read this as an early signal, not a rule change.

How many homes are we talking about?

More than most people assume. According to the Environment Agency's national assessment, as cited by Insurance Business UK, around 6.3 million properties in England sit in areas at risk of flooding from rivers, the sea or surface water. With climate change, that could reach roughly 8 million, about one in four, by mid-century. Aviva's Jason Storah put it similarly: "By 2050 a quarter of homes are likely to be at risk from flooding."

• 6.3mEnglish properties in flood-risk areas today (Environment Agency)
• ~8mpossible by mid-century with climate change
• 2028Flood Re's target for FPCs linked to discounted premiums
• 2039year Flood Re plans to exit the market

Note the phrase "in areas at risk". That is not the same as "will flood". A property can sit in a risk zone and never see a drop; another outside it can still get hit by surface water in a freak storm. Which is, rather neatly, the argument for a certificate that looks at the building as well as the postcode.

Why does Flood Re care about a certificate?

Because the money is about to change. Flood Re was set up so that households at higher flood risk could still get affordable cover. It is funded by a levy on home insurers, and it has a planned end date: Flood Re intends to leave the market in 2039, when household flood cover moves to fully risk-based pricing. In plain English, the subsidy goes away and insurers charge what the risk really costs.

That is a long runway, but it is not an infinite one. If you buy a home today and hold it for fifteen years, you are the owner who meets that change. A certificate that proves you have done the work to cut your risk is how Flood Re hopes you will be rewarded with cheaper premiums rather than a shrug. Its stated aim, according to the reporting, is to get FPCs linked to discounted premiums by 2028 and, over time, to have insurers recognise resilience actions.

Some related numbers from the same coverage, in case you hold a policy:

Item	What was reported
Contents-only cover, Council Tax Bands A and B	Flood Re charge falls from £52 to £25 from April 2027
Levy on home insurers	Rises from £135m to £160m a year
Homes built since 1 January 2009	Cannot be ceded to Flood Re
Build Back Better scheme	Taken up in only around a third of eligible cases
BeFloodReady	Being acquired by Flood Re, official launch 22 April 2027 in Birmingham

That row about homes built since 2009 is worth a second look if you own a newer property on a flood plain. Those homes sit outside Flood Re's protection. The coverage also notes a High Court ruling that allowed up to 190 homes on a floodplain site near Yatton in North Somerset, all of them outside Flood Re's reach. If you live in a newer estate, check your own insurance position rather than assuming the scheme covers you.

What does it mean if you are selling in the next two years?

Let me be direct. For most sellers, nothing changes this winter. You will not need a flood certificate to put your house on the market. What changes is the direction of travel.

Buyers already ask about flooding. Solicitors already raise it in the enquiries. Lenders and insurers already look at flood data when they decide whether to lend and what to charge. A formal rating would simply put that information in one place, in a form a buyer can understand in thirty seconds, at the very start of the process rather than halfway through conveyancing when a sale can wobble. I expect that to cut both ways:

Which side wins for you depends on your street, not on the national headline. A house on a hill in a flood-free postcode will barely notice. A terrace next to a river that has been in a risk zone for years will feel it first. The certificate is not creating the risk. It is making it visible.

Will a flood rating hit the value of my house?

Honest answer: nobody knows yet, and anyone who gives you a percentage is guessing. There is no pilot data to point to. What we do know is how buyers behave when something is documented: they price it in. We have seen it with EPC ratings and leasehold terms, and flood risk is hardly new to buyers in affected areas. The certificate will mostly formalise a discount, or a lack of one, that the market already applies in an untidy way.

If you want a sense of where your own home stands today, the sensible starting point is a realistic value. Our guide on how much your house is worth walks through how to get there, and the broader UK house prices guide for 2026 gives the market backdrop. Flood risk is one factor among many, and in a flat market, buyers who have plenty of choice are quicker to walk away from anything that looks complicated.

Does this affect the mortgage side of a sale?

Potentially, and this is where the Nationwide comment gets interesting. Robert Stevens of Nationwide said FPCs could help "people make more informed decisions about their homes". A separate Nationwide property risk expert reportedly called them a "really valuable tool for homeowners". Lenders like data. They already run flood checks as part of a valuation. If a standard rating lands, it is not a stretch to imagine it feeding into lending decisions, particularly for the higher-risk end of the market.

I would not panic about that yet. No lender has said it will decline or reprice on the basis of an FPC, and the pilots have not even started. But it is a reason to pay attention to how conveyancing works, because flood is already one of the issues that can slow a sale when a survey, a search or an insurer's quote comes back with a nasty surprise. A certificate that surfaces the issue early could genuinely speed things up. Or it could kill a few deals sooner. Both are plausible.

What is the regional picture?

Here the honest answer is "we do not know, because the pilot areas have not been named". The announcement says flood-prone parts of England, and the Environment Agency figure of 6.3 million properties is a national one. I am not going to invent a regional league table to fill the gap.

What I can say from how flooding works in this country is more general. Risk clusters along river valleys, low-lying coastal land and places where drains cannot cope with heavy rain. Plenty of those are not obvious flood zones on a map, which is why the surface water element of the rating matters. A city-centre street with poor drainage can score worse than a village by a river. If you are selling, the useful question is not "is my region at risk" but "what does the government's own flood-risk checker say about my postcode", because that is the data the certificate will lean on. It is free to look up, and a buyer's solicitor will do it anyway.

What should you do now if you plan to sell?

Nothing dramatic. A handful of sensible steps, in rough order of effort:

• Check your own risk. Use the government's "Check your long term flood risk" service for your address. If it says very low risk, you can relax and may even mention it in the listing.
• Dig out the paperwork. If you have ever had flood damage, repairs or insurance claims, find the details. Selling with half-remembered history is how deals fall apart late.
• Look at your insurance. Ask your insurer what they think of your property's flood risk and whether any resilience measures could lower the premium. The answer tells you what a buyer is likely to face.
• Price resilience measures sensibly. Self-closing air bricks and flood barriers are modest compared with a kitchen refit. Whether they are worth doing before a sale depends on your risk level and timeline. Do not spend thousands on the strength of a pilot scheme that does not exist yet.
• Get a realistic valuation. If risk is a factor in your area, a local agent's price may differ from an online estimate. A free valuation and offer comparison will show you how real buyers respond.

Is this a reason to sell sooner?

That would be the wrong lesson. The sellers who gain from a certificate are the ones with a good story to tell, and the sellers who lose are the ones caught unprepared. Neither group should rush to the market because of a pilot. If you were already planning to sell, you may as well get your flood facts straight first. If you were not, this announcement is not a reason to change your mind.

The one exception is if you already know you have a problem property. A house with a history of flooding, a difficult insurance position or a lender that has already pushed back is exactly the sort that gets harder to sell as information becomes more standardised. If that is you, it is worth looking at your full range of routes, including cash house buyers, who are used to pricing in awkward properties and do not need a mortgage lender's sign-off. Cash buyers will usually offer below open market value, so compare that against what you could realistically net after months on the market with a flood question hanging over it. We explain the trade-off in our guide on what percentage of market value cash buyers pay.

What if my house has already flooded?

You can still sell it. People do, every year. What matters is being open about it and having the evidence of what was repaired and what has changed since. You are legally expected to answer the seller's property questions honestly, and flooding history is the kind of fact a buyer's solicitor asks about directly. Hiding it is a bad idea that tends to end badly.

How does this fit the wider market right now?

It lands in a soft market. Nationwide's latest index showed house price growth slowing to 0.8%, and the RICS price balance fell to -32 in September, both of which we covered earlier this month. Buyers are cautious, mortgage costs are high and sellers have to work harder for a result. In that environment, anything that gives a buyer a reason to hesitate matters more than usual. A flood question is just the sort of thing that lets a nervous buyer reopen the price.

That is the real-world context for the certificate. In a booming market, sellers can shrug off risk labels because buyers are fighting for stock. When buyers have choice and money is tight, small things become negotiating points. The certificate itself is neutral. The market it arrives in is not.

What is the outlook?

Here is how I read the timeline, based on what has been reported:

When	What is expected
Before end of 2026	First FPC pilots begin in flood-prone areas of England
April 2027	Flood Re charge for contents-only cover in Council Tax Bands A and B falls to £25; BeFloodReady launches formally on 22 April
Through 2027 and beyond	Further pilots
2028	Flood Re's target for linking FPCs to discounted premiums
2039	Flood Re plans to exit; household flood cover moves to risk-based pricing

What could go wrong? Plenty. Pilots get delayed or watered down. Insurers might not recognise the ratings. Assessments could prove too costly or complicated for ordinary homeowners. Or the government might decide that a voluntary certificate is enough and never make it compulsory. Equally, the rating could become routine within a few years, much as the EPC did, once lenders and buyers start asking for it.

My view: this is a sensible idea whose success depends entirely on the money. If a good rating really does cut your insurance bill, homeowners will queue up for one. If it only produces a label, it will be one more bit of paper at the point of sale. Watch for the insurer buy-in. That is the test.

A word on how to read the headlines

You will see this story described as "EPC-style flood certificates will change how homes are sold". Technically that is a forecast, not a fact. As things stand, the pilots have no named areas, no published home count and no stated link to mortgage lending. The most reliable statements are the narrow ones: pilots begin before the end of 2026, the rating has three parts, and Flood Re is aiming for premium discounts by 2028.

Equally, do not dismiss it. A decade ago few buyers asked about energy ratings. Now they are a fixture of every listing. Flood information is on the same path. It will arrive gradually and unevenly, and the homes that benefit will be the ones whose owners got ahead of it.

What about flats, new builds and leasehold homes?

The announcement does not say how the pilots will treat them, so treat anything you read on this as speculation. What the reporting does say is that homes built since 1 January 2009 cannot be ceded to Flood Re. That makes a flood rating potentially more important for newer properties, because the safety net is thinner. If you own a newer house on a flood plain, your insurance position deserves a proper look before you list.

For flats, flood risk often sits with the building rather than your front door, and with the freeholder's insurance and maintenance decisions. If you are in that position, our comparison of freehold versus leasehold explains why tenure shapes how easily a home sells. I would expect leasehold sellers to get their answers from the managing agent first and the certificate second.
