Reinstatement Cost Assessments

One of the biggest risks to your premises, or your entire property portfolio? Being underinsured, most owners don’t even realise it. The cost to rebuild is almost never the same as your property’s market value. Without an up-to-date Reinstatement Cost Assessment (RCA), a claim could leave you with a massive shortfall to cover yourself, multiplied across multiple properties; the impact can be devastating.

An RCA tells you the real cost to rebuild from the ground up, demolition, debris removal, architect fees, structural work, legal costs, everything. It’s the only way to make sure your cover matches reality and your portfolio stays protected.

What is a Reinstatement Cost Assessment?

A Reinstatement Cost Assessment determines the estimated cost of reconstructing your building as if it were destroyed. It considers factors such as demolition costs, site clearance, building materials, labour, compliance with modern building regulations, and all associated professional fees.

Importantly, it excludes the market value or land cost and instead focuses solely on the cost of reinstatement, a figure used for insurance purposes to ensure the sum insured is accurate and reflective of the real risk.

An astonishing 76 per cent of British homes are underinsured. This will leave the policy short of rebuild value in the event of loss or damage. The homeowner will therefore need to fund the shortfall, potentially costing hundreds of thousands of pounds.
At worst, the expense can even bring into question the profitability of the scheme or business. This is where a professional valuation becomes essential to avoid relying on outdated or inaccurate figures.
Overvaluing the reinstatement value is also something that is objectionable. It is overbuying more than you need to cover what you do not need. An RCA prevents overvaluing the reinstatement value and ensures fair valuation for you, your premiums are sensible, and your cover is exactly right for you.
Most policies will have a current reinstatement cost assessment (RCA) as one of the conditions of your policy, particularly for commercial properties. Without one, your policy may be null and void or otherwise put into jeopardy of being less-than-covering.
Occasionally, RCAs will see that you are fulfilling these obligations and thus evading arguments when you need it most. The average clause often applied by insurers can drastically reduce your claim settlement if you're found underinsured, making up-to-date RCAs crucial.

Why Are RCAs Essential?

Failing to undertake a RCA can lead to being under- or overinsured, both of which come with serious financial implications.

Who Should Get an RCA?

RCAs are relevant to a wide range of property stakeholders. If you own, lease, or manage any form of real estate, obtaining an RCA is an essential part of your risk management strategy. It is especially critical for:

Commercial landlords
Property management companies
Housing associations
Local authorities
Owners of listed or heritage buildings
Businesses with multiple sites
Charities and institutions managing property portfolios
Resident management companies

Whether your property is an office block, retail unit, warehouse, apartment complex or care home, an RCA ensures that you are not left financially vulnerable.

How Often Should an RCA Be Carried Out?

Industry standard is that RCAs should be revised every three years. Updating will be obligatory every year where there have been significant changes, extensions or redevelopment of the property.

Updating yearly will be prudent in times of inflation or uncertain construction costs for the purpose of having the reinstatement value up-to-date. Keeping the declared value accurate is vital to ensure policy effectiveness and to avoid claim reductions.

Reinstatement Cost Assessment FAQS

An RCA includes the cost of demolishing the existing structure, clearing the site, rebuilding to modern regulations and standards, and paying professional fees such as architects, surveyors and engineers. It excludes land value and any market-driven elements. It also accounts for costs related to debris removal and other preparatory work before rebuilding.
While not a legal requirement in itself, many insurance policies require an up-to-date reinstatement cost to remain valid. Failing to carry out an RCA could result in a breach of policy conditions.
This depends on the complexity and size of the building. Most standard assessments can be completed within a few days of inspection, with a final report issued shortly afterwards. In some cases, an on-site assessment is required for full accuracy.
