Subsidence Survey for Subsidence Cracks

Caragh Bailey
3 min read
A subsidence survey, or report, also known as a Homecheck Mining and Subsidence Report, informs you if your property is in an area affected by subsidence due to soil shrinkage.

Subsidence is one of the greatest risks to properties and is the fear of many a home owner as the costs to repair can be in the tens of thousands.

Our structural engineers can carry out a specialist subsidence survey to determine whether the property is affected.

You can read more about subsidence and signs of subsidence here - What is subsidence?

A subsidence survey is often flagged by solicitors as a requirement during the conveyancing process because it has been highlighted within the Environmental Report in the Ground Stability Section.

This is not full confirmation that you have subsidence, only that there are man-made factors or natural factors which might affect the property in terms of its stability. 

Factors are considered within 25 metres and within 25-250 metres of the property. 

Risks are flagged up as before at the start of the report as ‘Identified’. Mortgage Lenders take subsidence very seriously and if they suspect that your property has any signs of subsidence then they may not lend you the money until the issue is addressed.

What is in a Subsidence Report?

  • Overall risk assessment
At the top of the report, in very large font size, is an overall opinion of your property's level of subsidence risk, from low to very high risk

  • Professional opinion
This next section explains in greater detail why your property has been given its risk rating. It further explains subsidence itself and then suggests ways in which you take actions to lessen your personal risk.

  • Detailed Subsidence Information
This section gives you an in-depth definition of subsidence and lists not just the main causes but many other indirect factors which may encourage the problem. The details provided can give you a greater number of points to consider when viewing any property you are considering buying.

  • Information about remedial work
This section explains what you should do if you have concerns about subsidence and, if it is found that a property has it, what certification any remedial work has to have to be regarded as legally acceptable.

  • Guide to high/very high risk ratings
This section makes clear that the report and its subsidence risk rating is essentially based on postcodes; an estimated 30% of postcodes in England and Wales have a high or very high risk. It explains what further checks you should carry out on the property to greater assess its risk, even if its postcode rating is high/very high.
