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 postcode is in one.
• Listed buildings within 100 m of this postcode: 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 within 100 m of this postcode. Planning applications are not here: there is no national open record of them.

Flood risk

Rivers, the sea or surface water: of the 37 address points in this postcode, 1 at high risk, 2 at medium risk and 4 at low risk. Each counts once, at the higher of its rivers-and-sea and surface-water risk.

Rivers and the sea alone: 1 at high risk, 2 at medium risk and 4 at low risk. Surface water and small watercourses alone: none is in an area at 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: the postcode centre is in flood zone 2. Zone 2 is between 0.1% and 1% a year from rivers (0.1% and 0.5% from the sea), ignoring defences. Welsh zones include an allowance for climate change.

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.
