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 Bampton at D−.

Bampton grades D− for hazard risk
Flood risk from rivers and the sea, against all 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.
Where the water goes in Bampton
Turn layers on and off. Blue is the risk from rivers and the sea; pink is where heavy rain collects. Both allow for flood defences.
The river and sea risk follows the River Exe, the River Batherm and the River Lowman. Surface-water risk is patchier: dips, underpasses and small streams.
14% of Bampton’s homes are at high or medium risk from rivers or the sea
The Environment Agency’s national map, allowing for defences. A further 2.5% are at low risk.
Share of each UK town’s homes at high or medium risk from rivers and the sea. 35% of UK towns have none; Bampton has more than 97% 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.
Rivers and the sea, more than heavy rain, are Bampton’s flood risk
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.
About 2.4% of homes are at high risk of surface-water flooding (a 1 in 30 chance or more each year) and 2.4% at medium risk: roughly 30 households. A further 6.9% face a low risk from surface water. That is more than 67% 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.
Bampton has flooded in 2 recorded years since 1969, most of all in 1969
Every flood the Environment Agency has mapped inside Bampton’s built-up area, newest first. The record is fullest for big river floods; small and surface-water floods are often missing.
- 2000December 2000: The River Exe overflowed3 hectares inside today’s built-up area · Surface Water: Bampton
- 1969September 1969: The River Batherm overflowed5 hectares inside today’s built-up area
The River Batherm covered 5 hectares of what is now Bampton in 1969, the largest flood the record holds here (September).
51 of Bampton’s households today live inside the outline of a recorded flood.
Since 1969, the largest recorded flood inside the village covered 3 hectares.
The River Batherm at Bampton Bridge: highest 2.03 m, in November 2012
The highest level each winter (October to September) at the Environment Agency’s Bampton Bridge gauge, since 2008. The river normally runs between 0.02 m and 0.90 m here.
- 25 November 20122.03 m
- 11 October 20121.92 m
- 21 November 20161.91 m
- 7 July 20121.79 m
- 7 June 20091.79 m
- 22 December 20121.73 m
The River Batherm has topped its normal range on 206 days since 2008, most in the winters of 2012–13 and 2023–24. By its highest day, the winter of 2025–26 was the 4th-highest of the 17.

Parts of Bampton are in radon Affected Areas, up to the Over 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 Bampton’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.

- Sign up free for Environment Agency flood warnings by text, call or email.
- Floodline: 0345 988 1188, 24 hours.
- Bampton’s warning areas include River Batherm at Bampton.
- 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.
- 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%.
- 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.
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.
- Past floods are what was recorded. The flood outlines come from surveys, aerial photographs and reports; many small floods, and most surface-water floods, were never mapped.
- 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.
