Planning and heritage
Conservation area: no postcode centre in this street's postcodes is in one.
Listed buildings on or by this street: 1.
Article 4 direction (removing permitted development rights): Small HMO Northern Extension, Small Houses in Multiple Occupation Article 4, Perry Hill Parade.
Tree preservation orders: none recorded, though not every council has published theirs.
Source: planning.data.gov.uk (Ministry of Housing, Communities and Local Government), compiled from councils and, for listed buildings, Historic England's National Heritage List. Conservation areas, Article 4 directions, tree preservation areas and the green belt are checked at each postcode's centre. Listed buildings and protected trees are counted on or by this street. Councils publish Article 4 directions, tree preservation orders and brownfield registers to different standards, and some not yet. Planning applications are not here: there is no national open record of them yet.

Flood risk
Rivers, the sea or surface water: in this street's postcodes, 36 addresses are in areas at high risk, 35 at medium risk and 60 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.

The street's 448 addresses are between 16 m and 23 m above sea level (20 m on average); the ground rises about 6 m from the lowest to the highest.
Source: Ordnance Survey, OS Terrain 50, July 2026: the height of the ground on a 50 m grid, read at each address, in metres above Ordnance Datum (mean sea level at Newlyn). It is the lie of the land, not floor or threshold levels, and is accurate to a few metres. Being low-lying is not in itself a flood risk; the flood section above says what the flood maps show.

Distances are straight lines from the middle of the street, not routes, and say nothing about how often anything runs. Stations opened since the end of ORR's year appear when ORR publishes the next one, each December; heritage railways are left out.

Air quality
Source: Defra, modelled background air pollution, annual means for 2024, for the 1 km square that holds the middle of the street. These are background levels, away from the kerb: beside a busy road nitrogen dioxide in particular can be several times higher. UK limits are the legal annual limits for England and Wales; the World Health Organization's 2021 guidelines are much stricter, and most towns and cities are above them.

These are models of traffic, not measurements; they leave out smaller airports and airfields, industry and neighbours, and a room at the back of a house is often much quieter than the front. The World Health Organization's guidelines are 53 dB for road traffic, 54 dB for railways and 45 dB for aircraft (below the lowest level shown here).

People and work
Source: ONS Census 2021, taken on 21 March 2021, for the 8 Output Areas (small census areas of about 125 households each) that this street's postcodes are in: 2,586 residents in 1,094 households. The census was taken during a lockdown, so working from home is high and travel to work low compared with now. ONS swaps a few records between neighbouring areas and adds small amounts of noise to counts to protect privacy, so small differences mean little. Industry is not published for areas this small.

Deprivation
The 6 neighbourhoods around this street are in deciles 1 to 5 of 10 on the English Indices of Deprivation 2025, where 1 is the most deprived tenth of England's 33,755 neighbourhoods and 10 the least.
Source: English Indices of Deprivation 2025 (Ministry of Housing, Communities and Local Government), by LSOA (about 1,500 people), through the ONS Postcode Directory. The index combines income, employment, health, education, crime, housing and living environment; it ranks areas against each other and does not describe any one household. Ranks in England and Wales are worked out separately and cannot be compared.

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.
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.
