Build Back Better: claiming up to £10,000 for flood-resilient repairs — and why resilience beats reinstatement

Adverse weather pushed UK property insurance payouts to a record £6.1 billion in 2025, according to the Association of British Insurers (ABI), with the average flood payout to a homeowner rising by around 60% to roughly £30,000. Against that backdrop, one number stands out: the Flood Re Build Back Better scheme offers up to £10,000 for flood-resilient repairs on top of a claim settlement — yet Flood Re reports that only around a third of eligible households take up the offer. For anyone responsible for a portfolio of properties, that gap between what is available and what is claimed is worth understanding in detail.

Every flood claim ends with a decision, whether it is made deliberately or by default: reinstate the property exactly as it was, or rebuild it so that the next flood does less damage. Most of the market still defaults to like-for-like. This post looks at what Build Back Better actually funds, where it applies (and, importantly for housing associations and commercial portfolios, where it does not), what the evidence says about the economics of property flood resilience, and how continuous monitoring changes the maths on repeat claims.

The problem: like-for-like reinstatement rebuilds the same vulnerability

When a property floods, the recovery process is long, disruptive and expensive. The ABI notes that fully drying out, repairing and restoring a flooded home typically costs between £20,000 and £45,000, and families or tenants can be displaced for months while strip-out, drying and refit work runs its course. For a housing association or portfolio operator, multiply that by every affected unit and add void costs, decant arrangements, resident welfare obligations and the operational load on repairs teams.

Here is the uncomfortable part: a like-for-like reinstatement puts back chipboard kitchens at floor level, sockets 300mm off the ground, gypsum plaster to the original line and standard airbricks — exactly the configuration that just failed. If the property floods again, the claim plays out again, usually at a higher cost, and the premium and excess conversation gets harder each time. Asset managers know this pattern well from properties that have claimed two or three times in a decade.

The reinstatement window is the one moment when resilience is cheap. The property is already stripped out, the trades are already on site, and the marginal cost of specifying a resilient refit over a standard one is a fraction of what a stand-alone retrofit would cost later. Choosing like-for-like at that moment is not a neutral decision; it is a decision to buy the same risk back.

What the Build Back Better scheme actually offers

Launched by Flood Re in April 2022, the Build Back Better scheme allows households insured with participating insurers to claim up to £10,000 towards property flood resilience (PFR) measures on top of the cost of repairing the flood damage itself. The money is not deducted from the settlement — it is additional, and it funds things like a professional PFR survey, flood doors and barriers, self-closing airbricks, non-return valves on drainage, sump pumps, raised electrical circuits, waterproof wall finishes and water-resistant kitchen units. Flood Re describes the intent as helping households recover not just to where they were, but to a stronger position for the next event.

Who provides it

Participation has grown steadily. Early adopters at launch included NFU Mutual, Aviva, Ageas, Lloyds Banking Group and LV= General Insurance, with Covéa, Hiscox and RSA joining later in 2022 and AXA UK subsequently committing as well, according to Flood Re and reporting in the trade press. By 2026, Flood Re stated that more than 70% of the UK residential insurance market offers Build Back Better. If a household policy is with a participating insurer, the offer should form part of the claims conversation after a flood.

The uptake gap

Despite that availability, uptake remains low. Flood Re's reform programme reporting has noted that Build Back Better has been adopted in only around one third of eligible cases, with long and complex rebuild processes and limited awareness cited as the main reasons. Flood Re has proposed reforms to change insurer incentives — including a lower cap on ceded claims where the scheme is not offered — and estimates that wider adoption of property flood resilience measures could reduce annual UK flood losses by up to £740 million. In other words, the mechanism exists, the funding exists, and the constraint is largely awareness and timing: the decision has to be made in the narrow window between strip-out and refit, when claimants are least equipped to think strategically.

Where Flood Re applies — and where it honestly does not

This matters for our readers, so let us be precise. Flood Re is a reinsurance scheme for household policies. Its eligibility criteria require, among other things, that the home was built before 1 January 2009, that the policy is held in the name of one or more individuals, and that the building is a single residential unit or part of a block of no more than three units. Flood Re's own guidance is explicit that housing association residential properties, company-held buy-to-let portfolios and larger blocks of flats are excluded.

So if you manage a housing association's stock or a commercial property portfolio, the £10,000 Build Back Better payment does not attach to your corporate buildings insurance. Where it does touch your world:

• Shared owners and leaseholders in eligible smaller buildings who hold their own qualifying household policies may have access to Build Back Better through a participating insurer — worth flagging in post-flood resident communications.
• The resilient reinstatement principle travels. Nothing stops a portfolio operator negotiating resilient repair with its commercial insurer or funding the resilience uplift itself at reinstatement, when the marginal cost is lowest. Some commercial insurers and loss adjusters will support resilient repair specifications; it is a question to ask at claim stage, not after refit.
• Direction of travel. Flood Re's reform programme and the government's wider flood resilience planning both point towards resilience-based repair becoming the expected standard. Portfolios that adopt the practice early build the evidence base — surveys, specifications, installed-measure records — that insurers increasingly want to see.

Do not let anyone tell you Flood Re covers your commercial schedule; it does not. But the logic behind Build Back Better applies to every building you operate.

The deeper issue: resilience economics at portfolio scale

The Environment Agency's updated National Assessment of Flood Risk, published in December 2024, found that around 6.3 million properties in England are in areas at risk of flooding from rivers, the sea or surface water — and, under its central climate projections, that figure grows to around 8 million, roughly one in four properties, by mid-century. That is not a reason for alarm; it is a planning baseline. For a portfolio of 50 or 200 sites, it means the probability that some of your assets sit in at-risk areas is high, and rising exposure is a quantifiable input to asset management plans rather than a surprise.

Property flood resilience measures come in two families, and the distinction matters for specification:

• Resistance measures aim to keep water out: flood doors, demountable barriers, self-closing airbricks, non-return valves on foul and surface water drainage, sump-and-pump systems. Individual components are modest purchases — airbrick covers, for instance, typically cost tens of pounds each — while engineered doors and barrier systems cost more and benefit from a professional survey.
• Recoverability measures accept that water may enter and are designed to cut the cost and duration of recovery: raised sockets and consumer units, waterproof renders and closed-cell insulation, solid floors with resilient finishes instead of chipboard and carpet, kitchen units in water-resistant materials, and appliances raised on plinths.

The financial case rests on the second family as much as the first. If the ABI's £20,000–£45,000 range is what drying and restoring a standard home costs, a recoverable interior converts much of that into a wash-down, dry-out and redecoration job measured in weeks rather than months. Flood Re's £740 million annual savings estimate for wider PFR adoption is a market-level number, but the mechanism behind it operates identically at portfolio level: lower severity per event, shorter voids, faster resident return, and a stronger negotiating position on premiums and excesses at renewal.

The reason uptake sits at a third rather than three-quarters is timing. A flooded household — or a stretched repairs team — is making dozens of decisions under pressure, and "shall we redesign the refit?" loses out to "get it back to normal". The organisations that capture the resilience opportunity are the ones that decided their reinstatement standard before the flood, wrote it down, and briefed their insurer, loss adjuster and contractors in advance.

What portfolio operators can do now

Before the next event, know your exposure and codify your standard. Map every asset against current flood risk data, identify the sites where resistance and recoverability measures make sense, and write a resilient reinstatement specification into your damage repairs policy so it is the default at claim stage rather than an improvisation. Our business flood plan checklist and runbook covers how to turn this into an operational document your teams will actually use, including who calls the insurer and when.

During the claim, ask the resilience question early. For eligible household policies, that means residents asking a participating insurer about Build Back Better before refit begins. For corporate programmes, it means instructing your broker and loss adjuster that you want resilient repair options costed alongside like-for-like — the price difference is often smallest exactly then. Keep records of every installed measure; a documented resilience history is an asset in future insurance conversations.

After reinstatement, close the loop with monitoring. Resistance measures only earn their keep if someone deploys the barriers, checks the pumps and moves vehicles and stock before water arrives — which requires warning time, at every site, every time. This is where manual methods break down: checking three government websites separately for 80 sites during a named storm is not a plan. FloodWatch aggregates official flood warnings from the EA, NRW and SEPA into a single portfolio dashboard, refreshes river, rainfall and tidal data every five minutes, and shows what has changed since your last check — so a small operations team can see which of 10 or 200+ sites needs action, task local staff to deploy measures, and export an incident brief for the board afterwards. You can read how multi-site teams structure this in our guide to monitoring flood alerts across multiple sites, or see the full capability set on our features page.

Resilient buildings plus timely warnings is the combination that actually reduces repeat-claim severity: the fabric limits the damage water can do, and the monitoring buys the hours needed to keep water out in the first place.

Conclusion: the cheapest resilience you will ever buy

The Build Back Better scheme puts up to £10,000 of resilience funding on the table for eligible household claims, and two-thirds of that opportunity is currently going unclaimed. For housing associations and commercial portfolios outside Flood Re's scope, the same principle holds even though the funding route differs: the reinstatement window after a flood is the cheapest moment you will ever have to make a building more resilient, and like-for-like repair quietly spends that moment on rebuilding the previous vulnerability. Decide your standard now, brief your insurers and contractors before the next event, and pair resilient fabric with portfolio-wide monitoring so measures are deployed when it counts.
