Drought

< Back to methodology

This dataset provides insight on the relative susceptibility to drought for your property’s location. With increasing temperatures and decreasing rainfall projected into the future, it is expected that areas of low susceptibility are expected to remain at the same level of susceptibility in the future, while areas of high susceptibility are expected to remain high in the future.

Why should I care about this?
Hotter temperatures and reduced precipitation will result in the higher likelihood of increased instances of drought. Properties that are in close proximity to higher levels of susceptibility to drought may be impacted by access to water, while drier soil conditions can impact structural foundations of properties.

How we use our data
The classification is based on the maximum aggregate risk of areas of 2k square metres of a base grid that the property intersects. If the maximum intersecting risk is "low" or "very low", the property will be labelled "suitable" and a green traffic light is assigned, if "medium" or "high" the property will be labelled "possibly_suitable" and an amber traffic light assigned, and if "very high", the property will be labelled "possibly_unsuitable" and a amber traffic light assigned.

Available Outcomes:

Suitable

The property is in an area classified with 'very low' or 'low' drought hazard meaning it will be less susceptible to drought and have suitable access to water. As a result, the risk of drought during heatwaves is likely low or very low.

Possibly Suitable

The property is in an area classified with 'medium' or 'high' drought hazard meaning it is more at risk from reduced access to water and drier soil conditions. As a result, the risk of drought during heatwaves is likely elevated.

Possibly Unsuitable

The property is in an area classified with 'very high' drought hazard meaning it is more at risk from reduced access to water and drier soil conditions. As a result, the risk of drought during heatwaves is like very high.

  • Recommend to the property owner that they may want to consider their retrofitting options. For a personalised retrofit report, please visit https://martello.greenval.co.uk/
  • We recommend that you may want to consider your retrofitting options. For a personalised retrofit report, please visit https://martello.greenval.co.uk/

  • We recommend that you may want to consider your retrofitting options. For a personalised retrofit report, please visit https://martello.greenval.co.uk/
  • Ensure the property has a reliable water source, especially if it relies on private supplies like wells or boreholes. Consider how resilient these sources are during extended dry periods, and whether additional infrastructure (e.g., deeper wells) may be required.
  • Look for homes that use drought-resistant materials and designs. Homes built with heat-reflective roofing, proper insulation, and drought tolerant landscaping can help manage heat and reduce water needs during dry periods.
  • Properties in clay-rich soils are more vulnerable to subsidence during droughts as the ground can shrink when dry. Review the property's history, and consult surveyors or specialists to assess the risk and potential need for future repairs.
  • Research local water usage regulations, especially during drought periods. Some areas may enforce strict water restrictions that could impact daily living and property maintenance, such as limits on garden watering or car washing.
  • Consider properties that already have or can be retrofitted with rainwater harvesting systems. These systems capture rainwater for non-drinking purposes like irrigation and toilet flushing, reducing reliance on external water sources during dry spells.
