Roadworks
Street works permits come from the Department for Transport's Street Manager, which covers England only.
Flood risk
Rivers, the sea or surface water: of the 29 address points in this street's postcodes, 28 at high risk, 0 at medium risk and 0 at low risk. Each counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: none is in an area at risk. Surface water and small watercourses alone: 28 at high risk, 0 at medium risk and 0 at low risk.
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.
Recorded floods
No recorded flood covers the centre of this street's postcodes.
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
No storm overflow outlet is within 1 km (0.6 miles) of the street's postcodes in this record, which covers the overflows reported to the Environment Agency: most of Wales's are reported to Natural Resources Wales instead.
Coal mining
This postcode is in a coalfield, in a low risk area: coal was mined in the area, but no workings shallow enough to matter for building are recorded.
Conveyancers usually still order a coal mining search (CON29M) for a home in a coalfield.
Radon
The postcode is in a 1 km square with radon potential up to 10 to 30%: up to that share of homes there is estimated to be at or above the Action Level of 200 becquerels per cubic metre. At least part of the square is a radon Affected Area, where 1% or more of homes are.
Radon is a natural radioactive gas from the ground that can build up indoors; long exposure raises the risk of lung cancer. A three-month test with two small detectors is the only way to know a home's level, and a high level can usually be brought down with a sump or better ventilation. Homes built here in recent decades should have radon protection under the building regulations (basic protection from 3%, full protection from 10%). UKHSA sells a radon report for a single address from its detailed map at ukradon.org.
Historic landfill
No historic landfill site is within 500 m (0.3 miles) of the street's postcodes.
Height above sea level
The street's 24 addresses are between 112 m and 115 m above sea level (113 m on average).

| Ysgol Gyfun Cwm Rhondda Welsh medium | Secondary | 11–19 | 1.8 km (1.1 miles) | Estyn reports · My Local School | Not published in Wales |
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. Wales publishes no school results tables.
Nurseries and childcare
Ofsted registers childcare in England only. In Wales, nurseries, playgroups and childminders are registered and inspected by Care Inspectorate Wales, whose directory of services lists them with their reports.

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 each figure on this page is matched to the street and worked out: methodology.
