Energy performance certificates

Source: Energy Performance of Buildings Register (MHCLG), register as at 1 November 2026. Latest certificate per address; certificates last ten years, so the oldest here dates from May 2012 and some homes have none. Address data © Ordnance Survey and Royal Mail, shown for understanding the energy efficiency of buildings only.

31 homes with a current certificate; median floor area 73 m². Most common: House, semi-detached (14); House, mid-terrace (12); House, end-terrace (5). Built: 1976-1982 (15); 1967-1975 (13); 1950-1966 (2). Tenure at assessment: owner-occupied (26); 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 directions, tree preservation orders and green belt: Wales has no national record of these; the council's planning department holds them.

Source: DataMapWales (Welsh Government): conservation areas compiled from the councils, and Cadw's listed buildings. Conservation areas are checked at each postcode's centre; some councils' boundaries in this layer have not been updated for years, so the council's own map is the one to rely on. Listed buildings are counted on or by this street. Planning applications are not here: there is no national open record of them.

Roadworks

Street works permits come from the Department for Transport's Street Manager, which covers England only.

Source: Department for Transport, Street Manager open data, permits and works up to 31 October 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

None of the 48 address points in this street's postcodes is in an area at high, medium or low risk of flooding from rivers, the sea or surface water on Natural Resources Wales's map. Outside those areas the chance is under 0.1% (1 in 1,000) a year.

High: 3.3% (1 in 30) or more chance of flooding a year. Medium: 1% to 3.3%. Low: 0.1% to 1%. The map allows for flood defences. Address points are every property record (UPRN) in the postcode, each counted if it is in an area or within 5 m of one (the maps stop at building walls); a few are not homes, such as garages, business units or caravan pitches. Counts cover whole postcodes, which can include other streets.

Flood zone for planning: no postcode centre is in flood zone 2 or 3. Welsh zones include an allowance for climate change.

Sources: Natural Resources Wales Flood Risk Assessment Wales: rivers, sea and surface water (loaded 30 October 2026), and Flood Map for Planning: rivers and sea (loaded 29 October 2026); address points from OS Open UPRN and the ONS UPRN Directory. 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.

Height above sea level

The street's 46 addresses are between 126 m and 140 m above sea level (135 m on average); the ground rises about 14 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)7.74010
Fine particles (PM2.5)5.7205
Particles (PM10)8.94015

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: Welsh Government, Environmental Noise Mapping 2022 (Wales), modelled with Defra's noise model for every road and railway in Wales and published in August 2023, through DataMapWales: 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 aircraft, 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 and 54 dB for railways.

Addresses by modelled noise level (Lden, dB)

11 of the street's 46 addresses are modelled at 55 dB or more from road traffic, above the WHO guidelines.

Climate, daylight and earthquakes

Monthly temperatures and rainfall, sunrise and sunset through the year, and earthquakes recorded nearby since 1970 are much the same across the area, so they are worked out once for Caerphilly: see them on the Caerphilly page.

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: 250 residents in 125 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 6 of 10 on the Welsh Index of Multiple Deprivation 2025, where 1 is the most deprived tenth of Wales's 1,917 neighbourhoods and 10 the least.

Source: Welsh Index of Multiple Deprivation 2025 (Welsh 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.

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.
