Flood & hazards in Embsay · Environment Agency

Surface water, more than the river, is Embsay’s flood risk: 7.9% of homes, against 1.1% from rivers or the sea

On the Environment Agency’s maps, which allow for flood defences, “high or medium” means at least a 1 in 100 chance of flooding from rivers or the sea in any year. Hazard risk puts Embsay at C.

In brief

What stands out about Embsay’s hazards

From the Environment Agency’s maps and records and the BGS radon atlas, below.

By hazard

What Embsay faces

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Not on this page: coastal erosion, subsidence and shrink-swell ground (the British Geological Survey licenses it), groundwater flooding and reservoir failure.
Hazard risk Grade

Embsay grades C for hazard risk

Flood risk from rivers and the sea, against all UK towns.

Homes at high or medium flood risk (1.1%)Fewer than 31% of UK towns

The share of homes at high or medium risk from rivers and the sea, ranked against every UK town of 1,000 or more: fewer homes at risk is better. Towns with none at high or medium risk are ordered by their share at low risk, so they don’t all share one score. Surface water and radon aren’t graded: they are described below.

The river and sea risk follows the River Aire and the Eller Beck. Surface-water risk is spread across the village, in dips, underpasses and along small streams, which is why more homes are exposed to it.

Rivers and the sea

Share of each UK town’s homes at high or medium risk from rivers and the sea. 35% of UK towns have none; Embsay has more than 69% of towns.

The Environment Agency’s Risk of Flooding from Rivers and Sea (NaFRA2, June 2026) counts each postcode’s homes by band; the shares weight those postcodes by Census 2021 households. The EA counts include homes built since 2021.

Surface water

Heavy rain puts about 7.4 times as many Embsay homes at risk as rivers and the sea do

Surface water is rain that falls faster than drains and the ground can take it. It is mapped separately from rivers and the sea, and it is not in the Hazard risk Grade.

Surface water7.9%
Rivers and the sea1.1%
0%7%14% of homes

About 4.1% of homes are at high risk of surface-water flooding (a 1 in 30 chance or more each year) and 3.9% at medium risk: roughly 60 households. A further 4.6% face a low risk from surface water. That is more than 86% of UK towns.

Our estimate: every address in the village (ONS NSUL) read on the Environment Agency’s Risk of Flooding from Surface Water map (NaFRA2, 2025), each postcode’s share weighted by its Census 2021 households. Neither agency publishes a count of homes for surface water, so treat it as a guide; one street can differ from the next.

River levels

The Eller Beck at Skipton Eller Beck Reservoir: highest 5.59 m, in March 2019

The highest level each winter (October to September) at the Environment Agency’s Skipton Eller Beck Reservoir gauge (Skipton Eller Beck Reservoir Upstream level), since 2018. The river normally runs between 0.22 m and 0.90 m here.

Radon

Parts of Embsay are in radon Affected Areas, up to the 10–30% band

Radon is a natural radioactive gas from the ground; long exposure raises the risk of lung cancer. The atlas gives the chance that a home in each 1 km square is above the UK action level (200 Bq/m³).

100% of Embsay’s built-up area is in a radon Affected Area (1% of homes or more above the action level), and 100% in squares of 5% or more.

The squares are indicative: each takes the highest band found anywhere inside it, so most homes in a coloured square are below it. Only a three-month test in the home gives a real answer.

In a cloudburst
  • Surface water rises in minutes, often with no warning issued: stay out of underpasses and dips.
  • Keep the gullies and drains outside your home clear of leaves.
  • Report a blocked road drain to the council.
Radon
  • Test over three months, in a living room and a bedroom.
  • Above 200 Bq/m³, a small sump and fan usually fixes it.
  • New homes in radon areas are built with protection: basic from 3%, full from 10%.

Before you buy or rent in Embsay
  • Check the address on GOV.UK’s long-term flood risk service: it gives rivers and sea and surface water separately.
  • Ask whether the home has flooded or had a flood insurance claim; the TA6 property form asks the seller.
  • Homes built before 2009 can get flood cover through Flood Re, the government-backed scheme; newer homes can’t.
  • Check radon for the address on UKradon.org (a small fee) or ask the seller for a test result.
How to read these numbers

What this data can and can’t tell you

  • Defences are counted. Both agencies’ maps allow for flood defences and the chance they are overtopped or fail, so a town behind a defence scheme can show few homes at high risk and many at low risk.
  • Surface water is our estimate. Neither agency publishes a count of homes at risk from surface water, so we read each address on the map. A flat on a hill and a basement in a dip can share a postcode.
  • One town, many streets. Risk is street by street. Check a specific address on GOV.UK’s long-term flood risk service before you buy or rent.
