Historic England ↗

Flood zone 3, rivers and sea

High chance: a 1 in 100 or greater annual chance from rivers, or 1 in 200 from the sea. Any development here needs a flood risk assessment. Defences are not counted.

The Environment Agency flood map for planning. Homes in zone 3 must also pass the sequential test. Surface water flooding is a separate map.

Nutrient neutrality catchment: River Usk

New homes and overnight accommodation must show nutrient neutrality before approval.

Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.

Brecon Beacons National Park

The park authority decides applications here. Great weight to conserving the landscape; major development restricted.

Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.

Special area of conservation about 17 m away: River Usk / Afon Wysg

Work nearby can need a habitats assessment.

Harm to a protected site is only accepted where there is no alternative and an overriding public interest.

SSSI about 17 m away: River Usk (Upper Usk) / Afon Wysg (Wysg Uchaf)

Natural England may need consulting, depending on what is proposed.

Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.

Radon affected area, class 5

An estimated 10 to 30% of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.

From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.

Scheduled monument about 133 m away: Castell-Du, Sennybridge

Its setting is a consideration for work nearby.

Nationally important archaeology protected by the Secretary of State. Work that affects the monument or its setting is rarely permitted.

Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area. Historic England, the Environment Agency, Natural England, the British Geological Survey and UK Health Security Agency (radon, contains BGS materials © UKRI) and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
