UK experiencing a surge in subsidence


The prolonged spell of hot and dry weather across the country could see the UK experience a surge in subsidence, according to new data from Sedgwick.

In a statement based on its weekly update on subsidence volumes, the company said: “There has been a rise of more than 350% over the past six weeks, and it is likely to rise further as the heat and abnormally dry weather continue to affect already dangerously dry soil conditions”. 

Referring to stats from the UK’s Meteorological Office Rainfall and Evaporation Calculation System (MORECS), the country is seeing the biggest changes for several years, as the effect of the prolonged sunny, dry weather has started to show in monitoring readings. 

Looking at the previous surge years of 2003 and 2006, the current position shows that the soil is drier than it was in 2003, but not quite as high as the surge of 2006.

A surge event will be dependent on how long the MORECS remains at this maximum level: in 2003 there were maximum readings for seven consecutive weeks and 2006 for four weeks.

Whether or not 2018 becomes a subsidence surge year is dependent on the weather remaining dry and warm into September. 

The Guardian recently reported that several big-name insurers have reported that subsidence incidents are up 20% compared to this time last year. The fear is that that those returning from holidays will see fresh damage, with an influx of subsidence claims in September.
