Gas and electricity use
No gas meters are recorded on the street's postcodes, against 97 electricity meters: it looks to be off the mains gas grid, or almost, with heating from electricity, oil, LPG or solid fuel (39 meters are on Economy 7, the off-peak tariff for storage heaters).
| Postcode | Electricity meters | Typical electricity | Gas meters | Typical gas |
|---|---|---|---|---|
| PE38 0NB | 62 27 Economy 7 | 4,569 kWh | none recorded | |
| PE38 0NX | 10 | 5,758 kWh | none recorded | |
| PE38 0NA | 25 12 Economy 7 | 2,833 kWh | none recorded |
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 PE38.
Council tax
What each band costs in King's Lynn and West Norfolk in 2026-27: Band D £2,430 a year on average, including the police, fire and any county and parish charges.

Energy projects nearby
No wind turbine or waste plant within 5 km (3.1 miles), and no solar farm, battery site or other project of 1 MW or more within 2 km (1.2 miles), of the street's postcodes, operating or planned.
Roadworks
No street works under way, planned or finished in the last three months on this street, in permits up to 31 October 2026.
Flood risk
Rivers, the sea or surface water: in this street's postcodes, 2 addresses are in areas at high risk, 1 at medium risk and 2 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: no home is in an area at risk.
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 |
|---|---|---|---|
| PE38 0NB | not in 2 or 3 | 2 / 1 / 2 | unlikely |
| PE38 0NX | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| PE38 0NA | 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
2 storm overflows within 1 km (0.6 miles) of the street's postcodes spilled 3 times, for 12 hours in all, in 2025. They discharge into Trib. Whitebridge Drain, White Bridge Drain River Great.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Southery Little London Ps Anglian Water | Trib. Whitebridge Drain | 0 | 0 | 490 m (0.3 miles) |
| Southery (Mill Dr) Stw Anglian Water | White Bridge Drain River Great | 3 | 12 | 720 m (0.4 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 1 to 3%: 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.
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. UKHSA sells a radon report for a single address from its detailed map at ukradon.org.
Historic landfill
No historic landfill site is within 500 m (0.3 miles) of the street's postcodes.
Height above sea level
The street's 73 addresses are between 9 m and 11 m above sea level (10 m on average).

Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| Southery Academy | Primary | 4–11 | 350 m | No overall grade (Nov 2024, graded inspection without an overall judgement): Quality of education: Good; Behaviour and attitudes: Good; Personal development: Good; Leadership and management: Good | 46% at the expected standard in reading, writing and maths, 0% at the higher standard (2025; 41% in 2024 and 44% in 2023) |
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.
Nurseries and childcare

Ofsted also registers 271 childminders and 51 home childcarers (nannies) in Norfolk. It does not publish their addresses, so they cannot be shown here; the council's family information service lists those taking children.

Traffic on nearby roads
No traffic count point is within 500 m (0.3 miles) of the street's postcodes. The Department for Transport counts every motorway and A road and only a sample of minor roads, so a quiet residential street usually has none.

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.
