Why Cost Reinstatement Assessments Are Essential – And Why Getting Them Wrong Can Be Costly

You are here: Home / Oander News / Why Cost Reinstatement Assessments Are Essential – And Why Getting Them Wrong Can Be Costly

4 March, 2026 by Barry Mason

In today’s uncertain economic climate, ensuring your property is adequately insured has never been more important. One of the most critical – yet often misunderstood – aspects of property insurance is the Cost Reinstatement Assessment (CRA). At Oander, we regularly see the serious consequences of properties being underinsured, usually as a result of outdated or inaccurate reinstatement values.

A Cost Reinstatement Assessment determines the true cost of rebuilding a property from scratch in the event of total loss. This includes far more than just bricks and mortar – professional fees, demolition and site clearance, compliance with current building regulations, inflation, and specialist materials all need to be factored in. Without a proper assessment, property owners are effectively guessing their insurance cover.

The Importance of Accurate Reinstatement Values

Many property owners assume that market value or previous insurance figures are sufficient. Unfortunately, this is one of the most common and dangerous misconceptions. Market value reflects location and demand – not rebuild cost. Meanwhile, insurance values that haven’t been professionally reviewed for several years often fail to account for rising construction costs and regulatory changes.

An accurate Cost Reinstatement Assessment ensures:

  • Your property is fully insured for the true rebuild cost
  • You avoid the financial shortfall that comes with underinsurance
  • Insurance claims can be settled smoothly and in full
  • Lenders and insurers remain confident in your risk management

With construction costs continuing to rise, even properties assessed just a few years ago may now be significantly underinsured.

Common Pitfalls to Avoid

There are several easy mistakes that can leave property owners exposed:

Relying on outdated figures
Build costs fluctuate regularly. What was sufficient cover five years ago may now fall far short of what’s required today.

Using market value instead of rebuild cost
These figures can differ dramatically, particularly in high-demand areas.

Online calculators or rough estimates
While tempting, these tools often overlook crucial elements such as professional fees, specialist materials, access issues, or heritage features.

Failing to review after alterations
Extensions, refurbishments, and upgrades all increase reinstatement cost and must be reflected in insurance cover.

The Risks of Getting It Wrong – Or Not Doing It at All

Underinsurance can have devastating financial implications. In the event of a claim, insurers may apply the “average clause”, meaning payouts are reduced in proportion to the level of underinsurance. For example, if a property is insured for only 70% of its true reinstatement cost, any claim could be reduced by 30% – even for partial damage.

In worst-case scenarios involving total loss, the shortfall could run into hundreds of thousands of pounds, leaving owners unable to fully rebuild.

Overinsurance, while less damaging, still results in unnecessary premium costs over time.

Simply put – inaccurate reinstatement values expose you to avoidable risk.
