Homes with gas used 17,638 kWh of it on average in 2024, 88% more than the district's 9,385 kWh, and 5,863 kWh of electricity, 22% more than the district's 4,794 kWh. There are gas meters for about 29% of the homes.
1 of its postcodes has no gas meters recorded among 10 or more homes: often flats heated by electricity, or homes off the gas grid.
| Postcode | Electricity meters | Typical electricity | Gas meters | Typical gas |
|---|---|---|---|---|

| BA20 2RH | 17 | 2,462 kWh | 14 | 12,816 kWh |
| BA22 9TH | 9 5 Economy 7 | 5,804 kWh | under 5 |
These are all the homes on each postcode, whatever their size and however many live in them, so they show the kind of homes and heating here rather than what any one home uses. The typical figure is the median: half the homes used less. The district is BA22.
Council tax
What each band costs in Somerset in 2026-27: Band D £2,561 a year on average, including the police, fire and any county and parish charges.

Flood risk
Rivers, the sea or surface water: in this street's postcodes, 0 addresses are in areas at high risk, 0 at medium risk and 1 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: of the 10 homes the Environment Agency counts, 0 are in areas at high risk, 0 medium, 1 low and 0 very low.
High: 3.3% (1 in 30) or more chance of flooding a year. Medium: 1% to 3.3%. Low: 0.1% to 1%. Very low: under 0.1%. The rivers and sea figures allow for flood defences. Counts cover whole postcodes, which can include other streets.
Flood zone for planning: no postcode centre on this street is in flood zone 2 or 3.
| Postcode | Planning zone | Addresses at high / medium / low risk | Groundwater |
|---|---|---|---|
| BA22 9TB | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| BA20 2RH | not in 2 or 3 | 0 / 0 / 0 | unlikely |

Recorded floods
No recorded flood covers the centre of any of this street's postcodes.
Recorded floods are where floodwater was seen or surveyed after a flood. Many floods were never mapped, an outline over a postcode's centre does not mean every home in it flooded, and homes outside one may have. Ask the seller whether the home itself has flooded.
Coastal erosion
No projected coastal erosion zone is within 1 km (0.6 miles) of the street's postcodes.
Storm overflows
9 storm overflows within 1 km (0.6 miles) of the street's postcodes spilled 112 times, for 210 hours in all, in 2025. They discharge into Dodham Brook Via Sws, Dodham Brook, Tributary of the River Yeo.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Hendford Lodge Medical Centre Cso Wessex Water | Dodham Brook Via Sws | 1 | 0 | 450 m (0.3 miles) |
| Coopers Mill Cso Wessex Water | Dodham Brook | 25 | 13 | 450 m (0.3 miles) |
| Horsey Lane Combined Sewer Overflow Wessex Water | Dodham Brook | 15 | 19 | 530 m (0.3 miles) |
| Cso at Newton Road Wessex Water | Tributary of the River Yeo | 21 | 138 | 750 m (0.5 miles) |
| Goldcroft Combined Sewer Overflow Wessex Water | Dodham Brook Via Sws | 40 | 16 | 900 m (0.6 miles) |
| Unit 4 Yeo Leisure Park Combined Wessex Water | Dodham Brook Via Sws | 2 | 6 | 900 m (0.6 miles) |
| Unit 5 Yeo Leisure Park Combined Wessex Water | Dodham Brook Via Sws | 4 | 11 | 900 m (0.6 miles) |
| Wyndham Hill Cso Wessex Water | Dodham Brook | 2 | 1 | 900 m (0.6 miles) |
A storm overflow lets sewage diluted with rainwater into a river, stream or the sea when heavy rain overwhelms the sewers, so the spills here affect the water they run into, not homes. A spill is counted the regulators' way: a first 12 hours, then each 24 hours it goes on.
Coal mining
No postcode centre on the street is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
The highest radon potential in the 1 km squares around the street's postcodes is 5 to 10%: up to that share of homes there is estimated to be at or above the Action Level of 200 becquerels per cubic metre. At least part of that area is a radon Affected Area, where 1% or more of homes are.
By postcode centre: less than 1% (2); 1 to 3% (5); 5 to 10% (1).
Radon is a natural radioactive gas from the ground that can build up indoors; long exposure raises the risk of lung cancer. A three-month test with two small detectors is the only way to know a home's level, and a high level can usually be brought down with a sump or better ventilation. Homes built here in recent decades should have radon protection under the building regulations (basic protection from 3%, full protection from 10%). UKHSA sells a radon report for a single address from its detailed map at ukradon.org.
Historic landfill
1 historic landfill site is within 500 m (0.3 miles) of the street's postcodes, the nearest 340 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| The Small House Dorchester Road, Yeovil | Not recorded | Inert | 340 m |
Closed tips can give off gas (methane and carbon dioxide) and leak into the ground for years. An environmental search, which conveyancers usually order, looks at landfill and contaminated land around the home; the council keeps a register of land it has found to be contaminated.
Height above sea level
The street's 43 addresses are between 45 m and 86 m above sea level (57 m on average); the ground rises about 41 m from the lowest to the highest.

Exam results are from the Department for Education's school performance tables (Explore Education Statistics, Open Government Licence), for all pupils at each school. The middle school in England had 63% at the expected standard at the end of primary school (2025), Attainment 8 of 46.0 at GCSE (2026) and an A level average of C+ (2025). Attainment 8 adds up a pupil's grades in eight GCSEs, with English and maths counted twice (90 is the most), averaged over the school's pupils. Progress 8 compares pupils with others who had the same results at the end of primary school; it is not published for GCSEs in 2025 and 2026, as those pupils sat no primary tests during the pandemic. Small year groups swing from year to year, and figures for very small ones are withheld.

Only collisions in which someone was hurt and which the police were told about are here: damage-only collisions and near misses are not, and some injuries are never reported. Positions are recorded by the police, usually to within a few metres. Each year's figures are published the following September.
Traffic on nearby roads
The busiest counted road within 500 m (0.3 miles) is the A30 between A37 and A3088, with 16,330 motor vehicles a day on average in 2025, 370 m from the street's postcodes.
| Road | Between | Vehicles a day | Lorries | Ten years before | Distance |
|---|---|---|---|---|---|
| A30 | A37 to A3088 | 16,330 counted 2025 | 2% | +7% since 2015 | 370 m |
| A37 | East Coker Rd to A30 | 14,477 estimated | 6% | +15% since 2015 | 440 m (0.3 miles) |
Each figure is the annual average daily flow: the motor vehicles passing the count point, both ways, on an average day of the year. A point is counted by hand on a weekday every few years and estimated from the trend on similar roads in between. Lorries are heavy goods vehicles, as a share of all motor vehicles.

Postcodes on this street
What this page cannot tell you
- Whether a particular house is at risk of flooding, subsiding or anything else: the flood map is a model of areas and there is no property-level data here.
- What a home is worth now: sales are historic prices for the homes that happened to sell.
- How safe the street is: crime points are moved to anonymised locations and many crimes are never reported; road collisions count only those in which someone was hurt and the police were told.
- Whether you would get a place at a school: distances are straight lines, not catchments.
- Who lives on the street now: census figures describe the small areas around it in March 2021, during a lockdown.
- How long a journey takes or how often anything runs: transport distances are straight lines to the nearest stops.
- Whether a GP practice is taking new patients, or a dentist new NHS patients.
- How loud a home is inside, or noise from industry, neighbours or smaller airfields: noise figures are models of road, rail and air traffic outside.
How each figure on this page is matched to the street and worked out: methodology.
