Energy performance certificates

Source: Energy Performance of Buildings Register (MHCLG), register as at 1 November 2026 (load in progress). Latest certificate per address; certificates last ten years, so the oldest here dates from October 2008 and some homes have none. Address data © Ordnance Survey and Royal Mail, shown for understanding the energy efficiency of buildings only.

91 homes with a current certificate; median floor area 97 m². Most common: House, semi-detached (59); House, detached (27); Bungalow, detached (2). Built: 1967-1975 (67); 1950-1966 (18); 1976-1982 (4). Tenure at assessment: owner-occupied (68); rented (private) (3).

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.

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.

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, 14 addresses are in areas at high risk, 7 at medium risk and 25 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.

Height above sea level

The street's 185 addresses are between 86 m and 95 m above sea level (89 m on average); the ground rises about 10 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.

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)8.64010
Fine particles (PM2.5)5.7205
Particles (PM10)11.94015

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).

Addresses by modelled noise level (Lden, dB)

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 4 Output Areas (small census areas of about 125 households each) that this street's postcodes are in: 1,038 residents in 472 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 10 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.

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.

All the streets in DH1 and across County Durham.

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.
