Gas and electricity use
No gas meters are recorded on the street's postcodes, against 80 electricity meters: it looks to be off the mains gas grid, or almost, with heating from electricity, oil, LPG or solid fuel (35 meters are on Economy 7, the off-peak tariff for storage heaters).
| Postcode | Electricity meters | Typical electricity | Gas meters | Typical gas |
|---|---|---|---|---|
| PE32 1JX | 21 12 Economy 7 | 3,690 kWh | none recorded | |
| PE32 1JY | 5 | 4,889 kWh | under 5 | |
| PE32 1SG | 54 23 Economy 7 | 4,592 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 PE32.

Flood risk
Rivers, the sea or surface water: in this street's postcodes, 7 addresses are in areas at high risk, 2 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 68 homes the Environment Agency counts, 7 are in areas at high risk, 3 medium, 0 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 |
|---|---|---|---|
| PE32 1JX | not in 2 or 3 | 1 / 2 / 0 | unlikely |
| PE32 1JY | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| PE32 1LE | not in 2 or 3 | 0 / 0 / 1 | unlikely |
| PE32 1SG | not in 2 or 3 | 6 / 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
No storm overflow outlet is within 1 km (0.6 miles) of the street's postcodes.
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.
By postcode centre: less than 1% (4); 1 to 3% (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. UKHSA sells a radon report for a single address from its detailed map at ukradon.org.
Historic landfill
3 historic landfill sites are within 500 m (0.3 miles) of the street's postcodes, the nearest 360 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| East Winch East Winch, Norfolk | from 1967 | Not recorded | 360 m |
| N E W S - Blackborough End Landfill Mill Drove, Kings Lynn, Blackborough End, Norfolk | from 2009 | Industrial, commercial, household | 430 m (0.3 miles) |
| Mill Drove Mill Drove,Blackborough End,Kings Lynn,Norfolk | Not recorded | Industrial, commercial, household | 440 m (0.3 miles) |
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 50 addresses are between 2 m and 16 m above sea level (10 m on average); the ground rises about 15 m from the lowest to the highest.

All the streets in PE32 and across King's Lynn and West Norfolk.
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.
