Homes with gas used 14,746 kWh of it on average in 2024, 64% more than the district's 9,013 kWh, and 3,573 kWh of electricity, 11% more than the district's 3,221 kWh. There are gas meters for about 100% of the homes.

| PO13 8FT | 9 | 3,579 kWh | 9 | 15,745 kWh |
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 PO13.
Council tax
What each band costs in Gosport in 2026-27: Band D £2,344 a year on average, including the police, fire and any county and parish charges.
| A | B | C | D | E | F | G | H |

Planning and heritage
- Conservation area: no postcode centre in this street's postcodes is in one.
- Listed buildings on or by this street: none.
- Article 4 direction (removing permitted development rights): none recorded, though not every council has published theirs.
- Tree preservation orders: none recorded, though not every council has published theirs.
- Green belt: no.
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
No address in this street's postcodes is in an area at high, medium or low risk of flooding from rivers, the sea or surface water. The rest are in areas at very low risk: less than a 0.1% (1 in 1,000) chance a year.
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.
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
The nearest projected erosion zone is 710 m (0.4 miles) from the street's postcodes (by 2105, if defences are not maintained or built).
| Projection | Policy for the frontage | Erosion | Distance |
|---|---|---|---|
| By 2055, with the shoreline management plan carried out | Hold the line Selsey Bill to Hurst Spit | none (the line is held) | 840 m (0.5 miles) |
| By 2105, with the shoreline management plan carried out | Hold the line Selsey Bill to Hurst Spit | none (the line is held) | 840 m (0.5 miles) |
| By 2105, if defences are not maintained or built | No intervention Selsey Bill to Hurst Spit | up to 125 m | 710 m (0.4 miles) |
Each shoreline management plan sets a policy for each stretch of coast: hold the line (keep defences where they are), managed realignment (let the shore move back in a controlled way), advance the line, or no active intervention. Erosion is the distance the shore may move back, counted from today, for the higher central climate change allowance. The maps are guidance from national modelling, not a survey of any one home; the council's coastal team can say more.
Storm overflows
1 storm overflow within 1 km (0.6 miles) of the street's postcodes spilled 1 time, for under an hour in all, in 2025. They discharge into The Solent.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Lakeside Lee-on-Solent Ceo Southern Water | The Solent | 1 | 1 | 1 km (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
Every 1 km square the street's postcodes are in is in the lowest band of radon potential: fewer than 1 home in 100 is estimated to be at or above the Action Level. It is not a radon Affected Area.
Historic landfill
4 historic landfill sites are within 500 m (0.3 miles) of the street's postcodes, the nearest 100 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| Sandhills Lane Lee-on-the-solent, Gosport, Hampshire | from 1973 | Industrial, commercial, household | 100 m |
| Land at Cherque Farm Lee on Solent, Gosport, Hampshire | from 1981 | Inert, commercial, household | 170 m |
| Areas In The Region Of Sandhills Lane Sandhills Lane, Lee-on-Solent, Hampshire | Not recorded | Industrial, commercial, household | 300 m |
| Chark Farm North of Privett Road, Lee-on-Solent, Hampshire | Not recorded | Inert, industrial, commercial, household | 320 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 addresses are about 8 m above sea level.

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.

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.
