Gas and electricity use
No gas meters are recorded on the street's postcodes, against 51 electricity meters: it looks to be off the mains gas grid, or almost, with heating from electricity, oil, LPG or solid fuel (28 meters are on Economy 7, the off-peak tariff for storage heaters).
| Postcode | Electricity meters | Typical electricity | Gas meters | Typical gas |
|---|---|---|---|---|
| PE8 5HS | 39 23 Economy 7 | 7,268 kWh | none recorded | |
| PE8 5HN | 12 5 Economy 7 | 6,645 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 PE8.

Flood risk
Rivers, the sea or surface water: in this street's postcodes, 1 address is in areas at high risk, 0 at medium risk and 5 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 51 homes the Environment Agency counts, 1 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 |
|---|---|---|---|
| PE8 5HS | not in 2 or 3 | 0 / 0 / 3 | unlikely |
| PE8 5HN | not in 2 or 3 | 1 / 0 / 1 | unlikely |
| PE8 5HT | not in 2 or 3 | 0 / 0 / 1 | 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 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: 3 to 5% (3); 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
No historic landfill site is within 500 m (0.3 miles) of the street's postcodes.
Height above sea level
The street's 64 addresses are between 18 m and 27 m above sea level (24 m on average); the ground rises about 9 m from the lowest to the highest.

Road safety
No collisions in which someone was hurt were reported on and around the street in 2021 to 2025.
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
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.
