Energy projects nearby
2 energy projects near the street's postcodes.
| Project | Kind | Size | Stage | Distance |
|---|---|---|---|---|
| BIOSSENCE SOLAR PARK Tonbridge and Malling 11/00985/FL | Solar farm | 4.5 MW | Operational Jul 2011 | 1.7 km (1.1 miles) |
| Allington EFW Maidstone 98/1212 | Energy from waste (incinerator) | 51 MW | Operational Dec 2008 | 2 km (1.3 miles) |
Planned projects can change or not go ahead; search the planning authority's applications by the reference shown for the plans, conditions and any objections. Construction brings traffic for some months; once built, solar farms and batteries are usually quiet, while turbines and waste plants can be seen or heard further away.
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, 12 addresses are in areas at high risk, 3 at medium risk and 24 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 39 homes the Environment Agency counts, 12 are in areas at high risk, 2 medium, 25 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: at least one postcode centre is in flood zone 3. Zone 3 is a 1% (1 in 100) or greater annual chance of flooding from rivers, or 0.5% from the sea, ignoring defences.
| Postcode | Planning zone | Addresses at high / medium / low risk | Groundwater |
|---|---|---|---|
| ME20 7BW | zone 2 | 0 / 0 / 10 | unlikely |
| ME20 7BS | zone 3 | 12 / 3 / 14 | unlikely |
Recorded floods
1 recorded flood covered 1 of the centres of this street's postcodes, most recently in December 1927 (Medway, Aylesford; sea).
| When | Flood | Source and cause | Postcodes |
|---|---|---|---|
| 25 Dec 1927 | Medway, Aylesford | Sea; channel capacity exceeded (no raised defences) | ME20 7BS |
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
1 storm overflow within 1 km (0.6 miles) of the street's postcodes spilled 5 times, for 2 hours in all, in 2025. They discharge into The Medway Estuary (Tidal).
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Hall Road Aylesford Cso Southern Water | The Medway Estuary (Tidal) | 5 | 2 | 620 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
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
2 historic landfill sites are within 500 m (0.3 miles) of the street's postcodes, the nearest 110 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| Old Aylesford Pit Aylesford, Kent | Not recorded | Inert | 110 m |
| Deacon Trading Estate Aylesford, Kent | 1976 to 1977 | Inert | 300 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 13 addresses are between 5 m and 6 m above sea level (6 m on average).

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.

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.
