Planning and heritage

Planning designations come from planning.data.gov.uk, which covers England only; Welsh conservation areas and listed buildings (Cadw) are not included yet.

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 within 100 m of this postcode. 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

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

For Wales only the planning flood zones are shown here; Natural Resources Wales's likelihood map (Flood Risk Assessment Wales) is not included yet.

Sources: Natural Resources Wales Flood Map for Planning: rivers and sea (loaded 29 October 2026). 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. Check an address on Natural Resources Wales's flood risk map.
