UK homeowners in flood-risk areas should review their buildings and contents insurance now, as the autumn flood season approaches and the Flood Re scheme faces ongoing pressure from climate change and rising claims. Premiums in high-risk postcodes have increased, and some insurers are tightening eligibility criteria. If your property has flooded before or sits in an Environment Agency flood zone, confirm your current cover limits, excess, and policy renewal date, and consider speaking to an FCA-authorised insurance adviser about your options before winter weather arrives.

What Is Changing

Flood Re, the government-backed reinsurance scheme launched in 2016 to keep flood insurance affordable for high-risk homes, is under periodic review as climate projections show more frequent and severe flood events across the UK. According to the Association of British Insurers, the scheme was designed as a transitional measure to give the market time to adapt (ABI, 2024). While Flood Re currently caps premiums for eligible properties, insurers are raising baseline premiums to reflect actual flood risk, and some households built after 2009 fall outside Flood Re eligibility altogether.

Homeowners renewing buildings or contents insurance in 2026 may see higher premiums, larger excesses (the amount you pay before the insurer contributes), or stricter terms around flood-resilience measures such as flood barriers or raising electrics. Insurers are also using more granular flood-risk data from the Environment Agency, meaning two homes on the same street can now receive different quotes based on precise elevation and drainage.

Why This Matters Now

The UK flood season typically peaks between October and February, driven by Atlantic low-pressure systems and heavy rainfall. Homeowners who delay reviewing their cover until claims surge in autumn may face longer quote turnaround times or limited insurer appetite for high-risk postcodes. Renewing early, or switching insurers during the calmer summer months, gives you time to compare policies, negotiate terms, and confirm that flood damage (including storm-driven surface water and river flooding) is included in your buildings and contents cover.

MoneyHelper advises homeowners to check whether their policy covers both buildings damage (structural repairs, damaged walls, floors) and contents damage (furniture, carpets, appliances) from flooding, and whether accidental damage or subsidence caused by flood-related ground movement is included (MoneyHelper, 2024).

What You Should Do

Check your current policy wording and key facts document to confirm flood cover is in place, and verify the policy excess. If you live in a known flood zone or have made a flood claim in the past five years, obtain quotes from at least three insurers: Flood Re-backed policies vary by insurer, and comparing options can reveal significant differences in premium, excess, and cover limits.

Consider flood-resilience measures such as installing flood doors, moving utilities above ground-floor level, or using water-resistant materials during renovations. Some insurers offer premium discounts or lower excesses for homes with certified flood defences, though requirements vary by provider.

Citizens Advice recommends reviewing your policy annually and updating your insurer if you make home improvements that reduce flood risk, as these changes may lower your premium at renewal (Citizens Advice, 2024).

Next Steps

Request a free flood risk assessment from the Environment Agency or check your postcode on their online flood map to understand your property’s flood zone classification. Speak to an FCA-authorised insurance adviser or broker if you are struggling to obtain affordable cover or if your renewal premium has increased sharply. Confirm your policy renewal date and set a reminder to review your cover at least 30 days before expiry, giving you time to switch insurers if needed.
