Climate Risk
The PropEco Climate Risk API can be used to retrieve a variety of information relating to the current and future environmental risks of a specific property or geographical location in Great Britain.
You can access, test and subscribe to the API at www.propeco.io/api.
GET /climate-risk
📄❓ See Code Samples (page bottom) for an example request.
Retrieves climate risk information about a specific property or location in Great Britain, identified by a UPRN, latitude & longitude, or X & Y grid position.
Query Parameters
uprn string Optional*
The UPRN (Unique Property Reference Number) of the property.
x_coord float Optional*
The X coordinate of the property or location in the BNG / EPSG:27700 coordinate system.
y_coord float Optional*
The Y coordinate of the property or location in the BNG / EPSG:27700 coordinate system.
latitude float Optional*
The latitude of the property or location in the WGS84 / EPSG:4326 coordinate system.
longitude float Optional*
The longitude of the property or location in the WGS84 / EPSG:4326 coordinate system.
*One of the following must be provided:
- An
x_coord&y_coordpair. - A

Response
The response combines assessments from multiple environmental and climate datasets. Results are grouped by risk category, with flood risk and coastal erosion assessments further organised by country.
The examples below illustrate individual sections of the response. Some fields or assessments may return null where data is unavailable or an assessment cannot be completed. A null value should not be interpreted as an absence of risk.
Distances are expressed in metres unless otherwise stated.

Rivers and seas: This assesses the current chance of flooding from rivers and the sea, taking account of flood defences and the condition they are in.
Rivers and seas with climate change: This outlines the estimated risk of future flooding from rivers and the sea, given projected climate change.
Surface water: This outlines the current chance of flooding from surface water.
Surface water with climate change: This outlines the estimated risk of future flooding from surface water, given projected climate change.
Assessments utilise the Environment Agency's latest National Flood Risk Assessment (NaFRA), which combines flood modelling and local expertise to assess flood risk at a resolution of 2m × 2m.
Flood risk is classified according to the following likelihood categories:
- High: each year, there is a chance of flooding of greater than 1 in 30 (3.3%).
- Medium: each year, there is a chance of flooding of between 1 in 30 (3.3%) and 1 in 100 (1%).
- Low: each year, there is a chance of flooding of between 1 in 100 (1%) and 1 in 1000 (0.1%).
- Very Low: each year, there is a chance of flooding of less than 1 in 1000 (0.1%).
For flooding from rivers and the sea, all four likelihood categories are represented.
For surface water flooding, only High, Medium and Low risk areas are explicitly mapped. Locations outside these mapped risk areas return null in the API response. However, given that surface water flooding can occur almost anywhere, these locations may be more appropriately interpreted as having Very Low risk, rather than no flood risk.
Note that climate change risk assessments are not available for all locations.

The API utilises the latest flood risk assessments provided by the Scottish Environment Protection Agency (SEPA). These identify locations at risk from coastal, river and / or surface water flooding and categorise at-risk locations according to their likelihood of flooding:
- High: Each year this area has a 10% chance of flooding.
- Medium: Each year this area has a 0.5% chance of flooding.
- Low: Each year this area has a 0.1% chance of flooding.
Both present day and future (given climate change) assessments are provided for each source of flooding.
Note that SEPA's Future Flood Maps model the Medium likelihood (0.5% annual probability / 1-in-200-year) flood event under a specified future climate scenario. It should not be interpreted as a complete estimate of the property's future annual flood probability.

The API utilises the latest flood risk assessments provided by Natural Resources Wales (NRW). These identify locations at risk from coastal, river and surface water flooding. At-risk areas are categorised according to their likelihood of flooding:
For rivers, surface water and small watercourses:
- High: each year, an area has a chance of flooding of greater than 1 in 30 (3.3%).
- Medium: each year, an area has a chance of flooding of between 1 in 100 (1%) and 1 in 30 (3.3%).
- Low: each year, an area has a chance of flooding of between 1 in 1000 (0.1%) and 1 in 100 (1%).
For the sea:
- High: each year, an area has a chance of flooding of greater than 1 in 30 (3.3%).
- Medium: each year, an area has a chance of flooding of between 1 in 200 (0.5%) and 1 in 30 (3.3%).
- Low: each year, an area has a chance of flooding of between 1 in 1000 (0.1%) and 1 in 200 (0.5%).
You can find out more about the underlying data here.
General Features
For each type of flooding, the API provides details of the nearest flood risk zone. Where the location being searched is within a flood risk zone, the distance is returned as 0. Otherwise, the nearest flood risk zone is returned where one is found within the relevant search radius (1km for rivers and seas, and 100m for surface water). If none is found within this radius, nearest_flood_risk_zone is returned as null.
annual_flood_risk is provided as a representative annual flood probability associated with the applicable risk category. This value represents a category threshold rather than a precise property-level probability; depending on the category, the actual probability may be above or below the value shown.
In addition, the API provides details of the highest risk flood zone within a 50m radius of the point being searched for. If none are found, this will be returned as null.
Note that the approach to assigning risk descriptions (such as 'High' or 'Low') differs between the flood risk datasets covering England, Wales and Scotland. The API presents these as they are used in the underlying datasets.
Note also that flood modelling is inherently uncertain and so the assessments provided should be treated as indicative.
Additional flood risk data
Additional flood risk datasets and assessments, including flood depth information, are available on request. Please contact us to discuss your requirements.

All responses contain the following summary fields:
-
has_nearby_erosion_zones: Whether any projected erosion zones were identified within the search radius.
-
nearest_zone_distance: Distance in metres to the nearest identified erosion zone, across both projection periods, management scenarios and climate allowances.
-
intersects_erosion_zone: Whether the assessment location intersects any identified erosion zone.
For polygon assessments, an additional coverage object reports the percentage of the assessed area intersecting projected erosion zones for each period, management scenario and climate scenario, on a scale of 0–100%.
Detailed results vary according to location (reflecting the nature of the underlying datasets), as set-out below.

The English coastal erosion assessment uses the National Coastal Erosion Risk Mapping (NCERM) dataset to identify areas potentially affected by coastal erosion and assess their proximity to a specified property or location.
The assessment covers two future time horizons:
-
Medium term (2055): Projected coastal erosion exposure by 2055.
-
Long term (2105): Projected coastal erosion exposure by 2105.
For each period, the projections object contains an array of nearby coastal erosion features, with the following information:
-
frontage_id: Unique identifier for the coastal frontage.
-
smp_no: Number of the relevant Shoreline Management Plan (SMP).
-
smp_name: Name of the relevant Shoreline Management Plan.
-
smp_policy_unit: Identifier of the relevant shoreline management policy unit.
-
defence_type: Type of coastal defence associated with the frontage, where available.
-
NFI: Projected erosion assuming no future intervention to manage coastal erosion.
-
SMP: Projected erosion assuming implementation of the relevant Shoreline Management Plan policies.
Each scenario includes the applicable policy and intervention information, where available, together with three climate scenarios:
-
climate_allowance_0 — Present Day: Baseline erosion projection using present-day climate conditions (2020), without additional future climate-change allowances.
-
climate_allowance_70 — Higher Central: Erosion projection incorporating the 70th-percentile sea-level-rise scenario.
-
climate_allowance_95 — Upper End: Erosion projection incorporating the 95th-percentile sea-level-rise scenario.
The future climate scenarios are based on UK Climate Projections 2018 (UKCP18), using the high-emissions RCP8.5 pathway. The 70th and 95th percentiles represent different levels of projected sea-level rise, rather than percentage increases in erosion or probabilities of erosion occurring.
Each climate scenario includes:
-
erosion_distance: Projected erosion distance in metres for the relevant frontage, scenario and period.
-
max_overlap: Maximum erosion overlap distance in metres recorded for the relevant projection.
-
assessment: Spatial assessment of the projected erosion zone relative to the specified location or geometry.
The spatial assessment contains:
-
intersects: Whether the assessment location or geometry intersects the projected erosion zone.
-
distance: Distance in metres to the erosion zone (zero when intersecting).
-
nearest_point: Coordinates of the nearest point on the erosion zone, including latitude, longitude, British National Grid coordinates and azimuth (bearing). This is null when the zone intersects the assessment location.
Important considerations
The two management scenarios represent different assumptions about future coastal intervention. The NFI scenario assumes no future intervention, while the SMP scenario reflects the relevant shoreline management policies, which may include maintaining existing defences or allowing managed coastal change.
The climate scenarios represent different assumptions about future sea-level rise and its potential impact on coastal erosion. They should not be interpreted as probabilities of erosion occurring at a particular property.
The projected erosion zones are effectively cumulative: the long-term (2105) zones incorporate virtually all areas identified in the medium-term (2055) projections. Consequently, polygon coverage represents the proportion of the assessed area potentially affected by each projection horizon.
The erosion_distance and assessment.distance fields measure different things. The former describes projected coastal erosion, while the latter measures the distance between the assessed location and the projected erosion zone.
A null scenario or climate allowance indicates that the corresponding assessment is unavailable. An empty projection array indicates that no relevant erosion features were identified for that period within the search radius.

The Scottish coastal erosion assessment identifies areas potentially affected by coastal erosion and provides information about their proximity to a specified property or location.
The assessment covers two future time horizons:
-
Medium term (2050): Projected coastal erosion exposure by 2050.
-
Long term (2100): Projected coastal erosion exposure by 2100.
For each period, the projections object contains an array of nearby erosion features, identified by erodeid. Each feature may include one or more of the following classifications:
-
eroded_area: Land projected to be lost to coastal erosion.
-
influence: Areas potentially affected by the impacts of coastal erosion.
-
vicinity: Areas near projected coastal erosion that may be exposed to associated risks.
Each classification includes:
-
intersects: Whether the assessment location or geometry intersects the zone.
-
distance: Distance in metres to the zone (zero when intersecting).
-
nearest_point: Coordinates of the nearest point on the zone, including latitude, longitude, British National Grid coordinates and azimuth (bearing). This is null when the zone intersects the assessment location.
Important considerations
-
The Scottish projections are based on a high-emissions climate scenario (RCP8.5, 95th percentile), assuming no coastal management intervention.
-
Erosion classifications can change between periods as coastal erosion progresses. Consequently, the coverage of an individual classification should not necessarily be expected to increase between 2050 and 2100.
-
A null classification indicates that no assessment is available for that classification within the particular feature. An empty projection array indicates that no relevant features were identified for that period within the search radius.

The Welsh coastal erosion assessment identifies areas potentially affected by coastal erosion and provides information about their proximity to a specified property or location.
The assessment covers three time horizons, compared with two for England and Scotland:
-
Short term (2005–2025): Coastal erosion projections for the initial assessment period.
-
Medium term (2025–2055): Projected coastal erosion over the following 30 years.
-
Long term (2055–2105): Projected coastal erosion over the subsequent 50 years.
For each period, the projections object contains an array of nearby erosion features, with the following information:
-
location_reference: Unique reference identifying the coastal location or frontage.
-
shoreline_management_plan_name: Name of the relevant Shoreline Management Plan (SMP).
-
local_authority_name: Local authority responsible for the area.
-
period: Start and end years of the projection period.
-
no_active_intervention: Projected erosion assuming no active coastal management intervention.
-
shoreline_management_plan: Projected erosion under the relevant Shoreline Management Plan policies.
Each available scenario includes:
-
erosion: Projected erosion distance in metres. The classification identifies how the estimate is expressed, while min and max specify the lower and upper bounds of a projected range. These values represent erosion distances, not probabilities or percentages.
-
intersects: Whether the assessment location or geometry intersects the projected erosion zone.
-
distance: Distance in metres to the erosion zone (zero when intersecting).
-
nearest_point: Coordinates of the nearest point on the erosion zone, including latitude, longitude, British National Grid coordinates and azimuth (bearing). This is null when the zone intersects the assessment location.
Important considerations
-
The two management scenarios represent different assumptions about future coastal intervention. A null scenario indicates that no corresponding erosion assessment is available for that feature and period.
-
Although individual projection periods have distinct start and end years, polygon coverage is calculated cumulatively, accounting for erosion zones identified in earlier periods.
-
An empty projection array indicates that no relevant erosion features were identified for that period within the search radius.

The API provides information on areas affected by historical wildfires, using mapped burned-area data to identify previous wildfire activity at a property or location.
The assessment identifies whether the location intersects a recorded burned area and returns details of all burned areas within the specified search radius, including their recorded burn dates, distances and nearest points.
Results provide an indication of historical wildfire activity but should not be interpreted as an assessment of current or future wildfire risk.
Burned areas are identified using NASA Earth observation data. As satellite-based detection has limitations, the dataset may not capture all wildfire events, particularly smaller fires or those that are difficult to detect. The absence of a recorded burned area should therefore not be interpreted as confirmation that no wildfire has occurred at a location.

The API provides water resource planning information for the Water Resource Zone (WRZ) containing the specified location. Forecasts are based on Water Resources Management Plan 2024 (WRMP24) supply-demand data.
All water volume measurements are expressed in megalitres per day (Ml/d), equivalent to millions of litres per day, unless otherwise stated.
Forecast Scenarios
Forecasts are provided for selected planning periods between 2026 and 2090, where available. The periods covered and completeness of the data vary between Water Resource Zones, depending on the information published by individual water companies. Where forecast values are unavailable, they are returned as null. Some Water Resource Zones may have no associated forecast data.
Each forecast contains two scenarios:
-
Baseline (baseline): The projected water supply-demand position before the preferred interventions in the water company's management plan.
-
Final plan (final_plan): The projected position after the preferred interventions are implemented.
Both scenarios include the following measures:
-
deployable_output: Quantity of water that can reliably be supplied under specified planning conditions.
-
water_available: Total water available for use, accounting for relevant supply adjustments.
-
distribution_input: Forecast water required by the distribution network.
-
target_headroom: Allowance for uncertainty in future supply and demand, including climate-related uncertainty.
-
available_headroom: Difference between water available and distribution input.
-
supply_demand_balance: Available headroom minus target headroom. Negative values indicate a projected deficit; positive values indicate a surplus.
-
supply_demand_balance_pct: Supply-demand balance expressed as a percentage of distribution input.
Climate Change Impacts
The climate_change object provides two additional measures:
-
deployable_output_change: Projected change in deployable output attributable to climate change, in Ml/d. Negative values indicate a reduction in reliable supply.
-
consumption: Volume of water consumption attributed to climate change, in Ml/d.
These measures describe climate-related pressures within the water resource planning forecasts and should not be added separately to the reported supply-demand balances.
Interpreting the Results
Forecasts represent planning scenarios rather than predictions of actual water shortages. They describe conditions across an entire Water Resource Zone, rather than water availability at individual properties.
Assessments are currently only available for locations in England.

The API integrates the MetOffice's UK Climate Projections (UKCP18) to provide the following projections:
Annual hot days. The number of days in which the maximum temperature exceeds 30°C that could occur each year. At such temperatures heat related illness, power cuts and transport disruption (due to overheating of infrastructure) become more likely.
Maximum temperature. Maximum daily air temperature (°C).
Winter precipitation. Average precipitation rates (mm/day) during December, January and February.
Summer precipitation. Average precipitation rates (mm/day) during June, July and August.
Projections are based on a high emissions scenario (RCP 8.5) and consider a range of plausible conditions which could occur in the future, namely global warming levels of 1.5°C, 2.0°C, 2.5°C, 3.0°C, 4.0°C above the pre-industrial (1850-1900) period. The range of possible outcomes reflects the uncertainty that is inherent in predicting climatic changes. The larger the difference between the lower and upper projections, the greater the level of uncertainty.
For each measure, the API provides:
-
Values for the 1981-2000 baseline (corresponding to 0.51°C warming).
-
Estimated upper and lower values for the range of plausible future warming levels (1.5°C - 4.0°C), as well as the absolute and percentage change (relative to the baseline) that these represent.
-
Estimated upper and lower values for the recent past (2001-2020), which corresponds to 0.87°C warming.
Note that the world warmed by around 1.1°C between 1850–1900 and 2011–2020.

The API response includes a generalised overview of susceptibility to the following six naturally occurring geohazards:
- Collapsible deposits
- Compressible ground
- Landslides
- Running sand
- Shrink–swell
- Soluble rocks
The assessments, which are provided by the British Geological Survey, place risks into one of three classes: Low, Moderate and Significant.
In addition, the API response provides an indicative assessment of potential change in subsidence risk due to climate change. Assessments are provided for two time periods (2030s and 2070s) under a high emissions scenario and three (2030s, 2050s and 2080s) under a medium emissions scenario. Assessments can be one of: Improbable, Possible, Probable or Unavailable.
