Flooding is an increasing concern for property owners and buyers, and for good reason — the risk is real, it affects insurance and value, and it is not always obvious from viewing a house on a dry day. Understanding flood risk, and how it fits into surveying a property, is an important part of buying with your eyes open.
The types of flood risk
Flooding does not only come from rivers. There are several sources, and a property can be exposed to more than one. River flooding is the familiar one, where watercourses burst their banks. Surface water flooding — sometimes called flash flooding — happens when heavy rain overwhelms drainage, and can affect properties nowhere near a river. There is also groundwater flooding, where the water table rises, and in some areas coastal flooding. A property’s risk depends on which of these apply to its location.
Why it matters
Flood risk affects a property in several practical ways. It affects insurance — homes in higher-risk areas can face higher premiums or more difficult cover, though schemes exist to help. It affects value and saleability. And, most obviously, it affects your life in the property: the disruption and cost of a flood are considerable, well beyond the water itself. Knowing the risk before you buy lets you factor it into your decision, your budget and your insurance.
What a survey considers
While detailed flood risk mapping is a specialist data matter, a building survey can consider the property’s setting and vulnerability — its location relative to watercourses and low ground, signs of previous flooding, the level of the property, and any flood resilience or protection measures in place or worth considering. Signs of past water ingress, and how the building has been affected and repaired, are exactly the kind of thing a surveyor is alert to. This complements the flood risk information available for an area, turning data into an understanding of this particular property.
Buying in a flood-risk area
A flood-risk area is not automatically a no. Many properties in such areas are perfectly good homes, protected by defences or resilient design, and priced accordingly. What matters is knowing — so you can assess insurance, consider protection measures, and buy with full awareness rather than discovering the risk after the first storm.
Get it understood before you commit
The worst time to learn about flood risk is after you have bought. Understanding it beforehand — through the available flood information and a survey that considers the property’s vulnerability — is simply part of buying sensibly.
At Emerald Ritter we survey properties across the region and consider flood vulnerability as part of understanding a building. If flood risk is a concern with a property you are buying, get it properly considered before you commit.
