Getting A Mortgage On A Flood Risk Property: What Lenders Actually Check

This page explains how lending decisions generally work. It is not mortgage advice, and Flood Risk Checker is not authorised by the Financial Conduct Authority. Lender criteria change often; a mortgage broker can tell you which lenders will consider a specific property.

Will A Lender Refuse A Mortgage Because Of Flood Risk?

A lender will not usually refuse a mortgage because of flood risk alone, but it can refuse if the home cannot be insured, if the valuation is affected, or if the flood history raises concerns. Groundsure, a conveyancing search provider, states that In the majority of cases getting a mortgage in a flood risk area is no problem at all.

Where refusals happen, they tend to follow from one of these:

1. No acceptable buildings insurance. Insurance is a condition of the loan.
2. A valuation that reflects flood history or risk. A lower valuation lowers the amount a lender will advance.
3. A flood search or survey the lender's instructions treat as a concern.
4. Other factors in the application that happen to coincide with the flood question.

Because criteria differ between lenders, a decline from one does not mean a decline from all.

How Does Flood Risk Actually Affect A Mortgage Decision?

A lender's concern is not the flood risk itself. It is whether the property can be insured for the life of the loan, because the home is the lender's security. If a flood destroyed an uninsured home, the loan would be secured on a damaged asset.

The chain runs like this:

The Law Society's TA6 notes make the same link for buyers: flood risk it may affect their ability to obtain buildings insurance and mortgage loans for the property. National Trading Standards tells estate agents that flood risk can affect mortgage availability, or affect the availability of relevant insurance products.

The practical rule: get a buildings insurance quote, with the flood excess, before you apply or before exchange. If the home is insurable, the flood risk question is usually answered.

What Does The Valuer Look At?

The lender's valuer assesses what the property is worth as security, and flood risk and flood history can affect that figure. The valuer is working for the lender, not for you, so a mortgage valuation is not a survey of flood protection.

What can influence the valuation:

• Market evidence. Research on England's housing market finds that a location within a flood zone significantly lowers property values even if we control for the proximity to a watercourse, the history of flooding and neighbourhoods effects, and that flooded homes flooded properties typically lose around 3% of their value immediately after a flood, with the loss rising to around 10% after 15 years.
• Flood history of the property, where known from the seller's answers or local knowledge.
• Insurability, where it affects saleability.

A valuation that comes in below the agreed price reduces the loan. If you need an independent view of the building's condition and flood resilience, commission your own survey.

Does Flood Re Make A Property Mortgageable?

Flood Re can make a property mortgageable by making buildings insurance with flood cover available, which is what the lender needs. It applies only to homes built before 1 January 2009 that meet all eight conditions, and only through an insurer that chooses to use it.

What Is A Retention And When Does Flood Risk Trigger One?

A retention is money a lender holds back from the mortgage until specified work is done: A mortgage retention is where the lender holds back part of the loan until essential repairs are completed. Flood risk on its own is not a repair, so the risk label does not trigger a retention; unrepaired flood damage found at valuation can.

When a retention might arise on a flood risk home:

• Visible flood damage not yet repaired, such as damp or damaged floors after a recent flood.
• Repairs the valuer considers essential to the home's value as security.

You then need to fund the work yourself before the retained money is released, renegotiate with the seller, or ask the seller to complete the repairs before exchange.

What Can You Do If A Lender Declines On Flood Risk?

If a lender declines on flood risk, find out exactly why, fix the underlying insurance or evidence problem, and then apply through a broker who knows which lenders consider flood risk properties. Groundsure advises that before applying with a new lender, you need to fully understand why you were declined.

The steps, in order:

1. Get the reason in writing if the lender will give it. Confirm it was flood risk and not another part of the application.
2. Get buildings insurance quotes that include flood, with the flood excess shown. Use the BIBA and ABI Flood Insurance Directory on 0370 950 1790 if standard insurers decline.
3. Check Flood Re eligibility for a home built before 2009.
4. Gather evidence: the seller's flood history answers, any flood protection certificates, and the flood search.
5. Use a specialist broker. Groundsure advises buyers to speak to a mortgage broker who specialises in flood risk.
6. Avoid many applications in a short time. Groundsure warns that applying for a mortgage affects your credit rating, so re-applying quickly can count against you.

If no insurer will cover the home on terms that satisfy a lender, that is a signal to reconsider the purchase; see buying a house in a flood risk area.

What Happens To Lending When Flood Re Ends In 2039?

Flood Re will remain in place until 2039, so a mortgage taken out now may outlast it. After 2039, flood cover for homes that rely on Flood Re is expected to be priced on each home's own flood risk, which is why resilience and a clean flood history matter for long-term insurability.

What this means in practice:

• A 25-year mortgage from 2026 ends in 2051, twelve years after the scheme's planned end.
• Flood Re's stated aim is a move to a future insurance market where flood risk is properly understood and reflected.
• Flood Re is introducing Flood Performance Certificates (FPCs), meant to help homeowners, buyers, renters and insurers better understand a property's flood risk and the measures that can reduce potential flood damage, and says it is working with insurers, lenders and industry partners on them.

Protection fitted now, with certificates kept, is the evidence a future insurer and lender can use. What measures cost is covered in property flood resilience, and how flood risk affects price in does flood risk affect house value.
