Insurance for a property with subsidence history

Whilst subsidence is a standard peril that is covered by most home insurance policies, once a property has suffered from subsidence insurers can be reluctant to offer this cover. This is when it necessary to look into the option of specialist subsidence insurers. At CoverBuilder we are subsidence insurance specialists who work with top UK insurers to ensure that any previously underpinned property is able to obtain the most comprehensive coverage possible, in order to protect against repeat subsidence.

You can find out more information about insurance after a subsidence claim through the ABI here


Insuring a property that has experienced heave

Similar to subsidence, heave also causes extensive damage to properties. This is the upward movement of the ground, often as a result of an excess of water causing the earth in the ground to expand. Again, the symptoms and effects of heave are similar to that of subsidence. The upward movement of a property causes serious cracking to walls, especially around windows and doors.

Discovering subsidence after changing insurance provider

The Association of British Insurers (ABI) has an agreement with its members which stipulates, should subsidence be identified within eight weeks of switching insurance provider, your previous insurer has the responsibility for handling the claim.


What is a Certificate of Structural Adequacy?

If your property has previously suffered subsidence then as part of our requirements to be able to offer you the best premium we can, there will need to be a Certificate of Structural Adequacy for the underpinning work previously done. When the repair has been organised as a result of an insurance claim, the insurer appointed Building Surveyor would have provided a Certificate of Structural Adequacy.  This is issued under the guidance of the Institution of Structural Engineers (1994) although there is no actual contractual or legal requirement for one to be provided, nor is this a form of guarantee.




5 ways to reduce the risk of subsidence impacting you



1. Plan where you plant trees and shrubbery

Avoid planting trees or large shrubs close to your home, garage, or outbuilding. Trees and shrubs can absorb a considerable amount of water from the surrounding soil resulting in shrinkage and destabilising of the foundations.

2. Take care of your gutters, downpipes and drains

Ensure that your drain system is tested regularly for any infestation or water leaks. Contact your local buildings maintenance firm to arrange the necessary checks.

3. Investigate any cracks in your walls

Whilst not all wall cracks are caused by subsidence, they can be an excellent early warning of a more serious problem. Often subsidence cracks are centered around doors and windows. You may also experience difficulty in opening/closing doors and windows due to the frameshifting.

4. Carry out the relevant research before buying a house with subsidence

Conducting the necessary checks for subsidence is recommended before committing to purchasing a property. Access to a surveyor’s report will enable you to discover whether the property has been previously affected by subsidence.

5. Deal with early warning signs quickly

If you notice any signs of subsidence from cracking or movement you should act fast to prevent as much future damage as possible. It’s highly advisable to contact your insurer as soon as possible.

What can cause subsidence?

Trees and shrubs can absorb a considerable amount of water from the surrounding soil resulting in shrinkage and destabilising of the foundations.


Subsidence from coal mining

When the land was still being intensively mined, it was a commonly used technique to dig the ground out in a grid pattern, leaving a series of rooms supported by pillars of un-mined coal which supported the mine roof and the surface. Over time, the ground surface can sink, shift or even collapse into the underground mine, causing movement of the ground above.

Subsidence from broker pipes

Leaking drains and pipes are the second highest cause of house subsidence and account for around 20% of all subsidence incidents. These can cause subsidence in 2 ways. Firstly this can soften the ground extensively, reducing its load-bearing capacity which can ultimately result in the downward movement of foundations. It can also wash away fine particles in a non-cohesive soil, reducing the volume of the soil, again causing foundations to sink or warp.


Subsidence damage to a property from tree roots

Tree roots can be known to grow directly under buildings, causing direct damage to the foundations and subsequent subsidence. However, the foundations of most buildings are strong enough to withstand this. A more common cause of subsidence as a result of trees is the way that their roots absorb moisture from the soil, particularly in clay areas where this can reuslt in dry cracked ground and movement of foundations.

What is the definition of subsidence?

This is the downward moment of earth beneath a property, moving with it the foundations on which the property was built. Subsidence can make it very difficult and costly for you to source the appropriate home insurance policy, thousands of properties are affected by subsidence each year.

Before assuming that your property is suffering from subsidence, it is important to examine the signs in great detail. Subsidence cracks are most likely to;

  • Exceed 3mm in width
  • Be visible on both the interior and exterior of the property
  • Form in weaker spots of the home (surrounding windows and doors)
  • Be wider at the top than at the bottom


Other indicators that may suggest your home is suffering from subsidence include;

  • Movement of the walls causing windows, doors and other openings to stick and become difficult to open.
  • Cracks appearing in the plasterwork inside your home
  • Cracks appearing in external brickwork
  • Cracks where an extension joins the main building


Is my property at risk of subsidence?

When buying a house there are lender requirements, specified in the Council for Mortgage Lender (CML) Guidelines, that you should be aware of:

  1. The Conveyancer must carry out any searches that may be appropriate to the property; considering its locality and other features (including subsidence).
  2. There could be a defect that is not covered by the lender’s valuation report. It is recommended that the borrower obtain more comprehensive reports from secondary surveys and not rely on the valuation report alone. These secondary reports should be more detailed reports on the condition and value of the property.
  3. The building requires a home insurance policy that covers the provision for damage resulting from an episode of ‘subsidence, heave or landslip’.


I think my property is subsiding. Who should I contact?

If you suspect your property is subsiding and you may need to make a subsidence insurance claim, contact a professional for further advice at the earliest opportunity. A builder or structural surveyor will be able to confirm if your property is affected by subsidence and provide a solution which may involve the removal of vegetation, relining of drains or the strengthening of your home’s foundations through underpinning.
