Energy performance certificates

Source: Energy Performance of Buildings Register (MHCLG), register as at 1 November 2026.

22 homes with a current certificate; median floor area 85 m². Most common: House, mid-terrace (11); House, semi-detached (6); House, end-terrace (4). Built: 1900-1929 (14); 1930-1949 (5); before 1900 (2). Tenure at assessment: owner-occupied (14); rented (private) (6); rented (social) (1).

Bands are charged as fixed shares of Band D; the actual bill depends on the parish and on discounts such as the single-person discount.

Listed buildings

Brownfield land registered for housing within 1 km (0.6 miles)

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.

Roadworks

No street works under way, planned or finished in the last three months on this street, in permits up to 30 September 2026.

Source: Department for Transport, Street Manager open data, permits and works up to 30 September 2026. It is published once a month, so works arranged or started since then are not shown, and dates are the ones planned unless the works have started or finished. Emergency works are often permitted after they begin.

Flood risk

Rivers, the sea or surface water: in this street's postcodes, 0 addresses are in areas at high risk, 0 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: 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 is in flood zone 2 or 3.

Sources: Environment Agency Flood risk: postcode search tool data (loaded 29 October 2026), Risk of Flooding from Rivers and Sea: postcodes in areas at risk (loaded 29 October 2026) and Flood Map for Planning (loaded 28 October 2026). Flood zones are checked at each postcode's centre point. These are models of areas, which their publishers say are not suitable for showing whether an individual property is at risk, and they do not cover flooding from sewers or drains. Check an address on the official long-term flood risk service.

Height above sea level

The street's 36 addresses are between 35 m and 37 m above sea level (36 m on average).

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.

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.

Annual means in µg/m³ (micrograms per cubic metre of air)
PollutantHereUK limitWHO guideline
Nitrogen dioxide (NO2)8.74010
Fine particles (PM2.5)7.1205
Particles (PM10)10.94015

All three are within the UK legal limits; PM2.5 is above the WHO guideline, as in most towns and cities.

Road and rail noise

Source: Defra, strategic noise mapping Round 4 (England), modelled for 2021 and published in December 2023, and its airport maps of the same round for the fifteen largest English airports, published in April 2026: Lden, the average sound level over a whole day with extra weight for the evening and night, on a 10 m grid, read at each address. 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).

Crime within 250 m

Source: data.police.uk street-level crime, September 2025 to August 2026. Police forces move every crime to the nearest of about 760,000 anonymised map points before publishing, so these are crimes near this street, not on it, and a busy point can collect crimes from a wider area. Counts are of records, not convictions.

People and work

Source: ONS Census 2021, taken on 21 March 2021, for the Output Area (a small census area of about 125 households) that this street's postcodes are in: 298 residents in 159 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 neighbourhood around this street is in decile 7 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.

Ranks in England and Wales are worked out separately and cannot be compared.

What has changed

Nothing new since the change feed started on 30 October 2026. New sales and energy certificates, and hygiene ratings, school inspections and flood figures nearby, will be listed here as the sources update.

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.
  • 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.
