NP4 9SF — Torfaen
Located as: postcode centre of NP4 9SF
Every section below is checked live against official public sources for this exact location — the coalfield map, flood assessments, geology, crime, planning portals, schools, energy certificates and the sales register. Generated 2026-09-23. Context before you commit — not a survey.
Plain-English summary
NP4 9SF is inside the coalfield but in a Development Low Risk Area — no high-risk legacy features are recorded at this point, though a CON29M search remains standard practice in conveyancing here. It is in a statutory coalfield consultation area, so planning applications are referred to the Authority. No recorded mine shaft or adit was detected within ~100 m of the postcode point. Flood: Outside NRW Flood Zones 2/3 (rivers & sea) — lowest mapped risk. BGS records significant landslide/slope instability potential in this area — geology context worth raising with a surveyor. Radon potential is lowest band — under 1% of homes above the action level; a home test costs about £50 if you want certainty. The postcode has 16 recorded sales since 1995, most recently £170,000 in 2025-07. 7 planning applications were made within 500 m in the last five years, 1 still open — worth reviewing on the council portal before you commit. This is a screening assembled from public data — not a survey, valuation, or substitute for professional advice.

Compiled from council planning portals via PlanIt. About a quarter of records are located only by postcode, so distances are indicative. An open application near a home you're buying is worth reading in full — the portal link shows plans, objections, and deadlines for comments.
Market
Sales history (HM Land Registry): 16 recorded sales in this postcode since 1995 — latest £170,000 (terraced, freehold) in 2025-07; median of the last decade's 2 sales £215,000.
Every recorded sale in this postcode (HM Land Registry, since 1995). For scale, the average England home is roughly £290,000 on the UK House Price Index. Hover a dot for price, type, and date.
Property, energy & broadband
9 dwellings have a current energy certificate in this postcode. Add a house number to the search to pinpoint one.
Current EPC bands across the postcode (latest certificate per dwelling; MHCLG register, England & Wales). A is best. New builds must reach B; the average UK home is D.
Broadband availability (Ofcom): gigabit-capable full fibre reaches 100% of premises here.
Share of premises in this postcode that can order each speed tier (Ofcom Connected Nations, availability not take-up). Gigabit is usually full-fibre (FTTP). Actual speed depends on the line and package you choose.
Flood & water
Planning designation (rivers & sea, defences ignored): Outside NRW Flood Zones 2/3 (rivers & sea) — lowest mapped risk.
Why these can differ: flood zones are the planning designation for rivers and sea only, ignoring defences; the likelihood bands include flood defences and add surface-water (rainfall) flooding, which zones never show. All measured at the postcode centre point — the official flood map draws the exact boundary.
Environment & nuisance
Air quality (Defra 2024 modelled background): PM2.5 annual mean 5 µg/m³, NO₂ 3.7 µg/m³. For scale: the WHO guideline is 5 (PM2.5) and 10 (NO₂); UK legal limits are 20 and 40.
Annual-mean concentrations (µg/m³) modelled on Defra's 1 km background grid — roadside spots run higher. Most of the UK sits above the strict 2021 WHO guidelines; the UK legal limits are the compliance test. Dot colour: green = within WHO guideline, amber = above WHO, red = above the UK legal limit.
Ground & geology
Measured ground motion (satellite radar, EGMS 2020–2024): the nearest measured 100 m cell (32 m from this point) moved at -0.4 mm/yr vertically — stable (average across 12 cells within 300 m: -0.7 mm/yr). This is actual measured movement of the ground surface, not modelled susceptibility — slow, broad motion of the block, not a verdict on any one building. National context: Sinking Britain, our nationwide analysis.
Natural ground stability (BGS GeoSure): landslide/slope instability — significant. Area-level geology context, not a property assessment.
BGS GeoSure rates six natural ground-hazard themes per area on a Low → Moderate → Significant scale; themes not shown are below Moderate here. Shrink–swell clay is behind roughly three-quarters of UK subsidence claims.
Clay-shrinkage outlook (summer 2026): no moderate or significant shrink–swell clay is mapped for this area, so this summer’s soil-moisture deficit is not a subsidence driver for this ground. National picture: our subsidence-claims forecast.
Radon potential: lowest band — under 1% of homes above the action level (UKHSA/BGS indicative atlas, 1 km grid).
Mining & coalfield
🏛️ Statutory coalfield consultation area — planning applications here are referred to the Mining Remediation Authority.
Recorded mine entries: no recorded shaft or adit detected within ~100 m of the postcode point. Entries may still exist in the wider area — see the map.
