Market Value vs Declared Value for Insurance Purposes

Market value seeks to answer, “What price would an asset or property interest exchange for in the market at the valuation date?”. Under the current International Valuation Standards, Market Value assumes a properly marketed, arm’s-length transaction between willing, knowledgeable and prudent parties, acting without compulsion. It reflects the asset’s market, legal interest, actual characteristics and highest and best use.

Declared value for insurance purposes answers a different question – “What would it cost, at the start of the policy period, to reinstate or replace the insured property following a major or total loss, on the basis required by the policy?”. On a conventional UK Day One reinstatement basis, it is the inception-date reinstatement cost before future inflation, including the rebuilding/replacement cost and the policy-relevant associated costs such as demolition, debris removal and professional/statutory fees. It is an insurance cost assessment, not a sale valuation.

The word “value” is potentially misleading: market value is an exchange-price concept; declared value is ordinarily a cost-to-reinstate or replace concept used to establish insurance cover. There is no reliable percentage relationship between them and either can exceed the other.

Market value: Hypothetical transaction price at the valuation date.
Declared value: Day One reinstatement or replacement cost at policy inception, before future inflation.
Policy sum insured: Usually the declared value plus the policy’s inflation provision, subject to the actual wording.

Market value vs declared value: direct comparison

Issue	Market value	Declared value for insurance
Primary purpose	Sale, acquisition, secured lending, financial reporting or another transaction/value purpose.	Establishing the amount declared to insurers for property-damage cover and testing adequacy under the policy.
Core premise	Hypothetical exchange between market participants after proper marketing.	Reinstatement or replacement following damage, usually on a total-loss and “new-for-old” or replacement-as-new basis.
Date perspective	Market conditions and asset circumstances at the valuation date.	Costs applying at the start of the insurance period; future inflation is normally dealt with separately.
Land	A property market valuation normally reflects the legal interest in the land and buildings, including location, development potential and market demand.	Land is usually excluded from insurance. The assessment instead covers the insured buildings and relevant site improvements, foundations, services, externals and other items falling within the policy definition.
Age, condition and obsolescence	Affect market participants’ bids and therefore market value.	Normally no depreciation merely because an insured building or machine is old where cover is replacement-as-new. Depreciation may apply under an indemnity, actual-cash-value or “reinstatement less wear and tear” wording.
Demolition/debris	Not added as a standard component of market value, although anticipated clearance liabilities may influence what a purchaser will pay.	Normally included where required by the policy, including demolition, debris removal and potentially shoring/making safe.
Professional/statutory fees	Buyer’s and seller’s transaction costs are not added to the reported market value.	Fees necessarily incurred in reinstatement, such as architects, engineers, surveyors, planning and Building Regulations costs, are normally included where insured.
VAT/taxes	Market value is the exchange price before direct buyer/seller transaction costs and taxes.	VAT treatment depends on recoverability, the insured’s tax status and the policy. The assessment should state whether VAT is included or excluded.
Inflation	No separate future inflation provision: it is a valuation as at a stated date.	Day One declared value excludes later inflation; the insurer normally applies a separate uplift to establish the policy sum insured or limit.
Typical output	An opinion of value on a stated basis, date and transaction premise.	Declared value plus, where relevant, reinstatement period and information enabling the inflation provision and sum insured to be set.

The RICS building standard expressly states that a declared value has no direct relationship with a property’s market value. It also requires the assessor to clarify whether the instruction is a building RCA rather than a Red Book market valuation, and to identify what the policy treats as “buildings”, including tenant improvements, fixtures, services and external works.

1. Market value: the transaction concept

RICS defines market value as:

“The estimated amount for which an asset or liability should exchange on the valuation date between a willing buyer and a willing seller in an arm’s-length transaction, after proper marketing and where the parties had each acted knowledgeably, prudently and without compulsion.”

The premise is a market exchange, not recovery following an insured loss. The amount reflects factors that market participants would recognise, including tenure, location, demand, alternative-use potential, income generation, condition and obsolescence. It excludes special value available only to a particular purchaser and represents the asset’s highest and best use where legally permissible, physically possible and financially feasible.

For plant and machinery, the transaction premise must be particularly clear. The market result can differ materially depending on whether the subject is an individual machine, an integrated operational facility, an in-situ asset, or equipment assumed to be disconnected and removed. Asset grouping, availability of associated assets and assumptions therefore need to be explicitly stated rather than silently transferred from an insurance assessment.

2. Declared value: the insurance cost concept

For buildings, the current RICS professional standard defines the usual requirement as a Day One reinstatement figure known as the declared value. It should represent a fixed-price, lump-sum competitive tender for work commencing on the first day of the policy, together with appropriate demolition, associated-cost, professional and statutory-fee allowances.

A building assessment will normally consider:

rebuilding the existing building, including basements, foundations and retaining walls
landlord’s alterations, fixtures and fittings
necessary modifications to comply with current statutory requirements
relevant drainage, utilities, boundary structures, outbuildings and external works
demolition, site clearance, debris removal and abnormal access or hazardous-material implications
professional, planning, Building Regulations and other statutory fees, and
VAT where it is non-recoverable or otherwise required by the policy.

Declared value is not always identical to “replacement cost” as a bare construction figure. Replacement or rebuilding cost is usually the core cost; the declared value is the policy-facing figure after adding the associated components required by the wording.

Conversely, some costs—land acquisition, financing, loss of rent, business interruption, contamination remediation, claim-preparation fees or separately insured assets—may be outside the property declared value unless expressly included.

3. Day One structure

Under the usual Day One mechanism:

Declared value = reinstatement cost at policy inception, with no future inflation allowance.

Inflation provision = percentage uplift intended to cover cost escalation during:

the remaining policy year; and
the redesign, consent, procurement and reconstruction period.

Policy sum insured or limit = declared value plus that inflation provision, subject to the precise wording and schedule.

Importantly, some policies index the declared value, some index the sum insured, some apply indexation only after loss, and some use a single inflation-inclusive sum insured rather than a conventional Day One structure. The schedule and wording must therefore be checked rather than assuming that all policies operate identically.

A common Day One average condition compares the declared value with the correct inception-date reinstatement cost, rather than comparing the inflation-uplifted sum insured with the Day One cost. The insurer’s maximum overall liability normally remains the stated sum insured. This is typical, but the actual test and any tolerance must be taken from the individual wording.

4. Consequences of using market value

Using market value as the declared value can cause either:

underinsurance, where rebuilding or replacement cost exceeds market value; or
overinsurance and unnecessary premium, where a high land/location-driven market value exceeds the insurable reinstatement exposure.

Zurich expressly advises that market value should not be used for building insurance because it may produce either outcome. AXA similarly warns against using purchase price or perceived market value and states that the sum insured should instead reflect rebuilding or replacement cost.

Where a policy contains an average condition, a partial claim may be reduced in the same proportion as the underinsurance. AXA illustrates the typical calculation: if property is insured for 50% of its correct rebuilding value, a £10,000 repair claim may be reduced to £5,000. For a total loss, settlement may also be capped at the sum insured.

However, average is wording-dependent, not a universal unqualified rule. Some policies apply Day One average by reference to the declared value; others use an 85% or other condition, index-linking arrangement, waiver, margin or alternative remedy. The Financial Ombudsman also considers what information was requested, how clearly the implications were explained and how the insurer or broker treated the customer, particularly in consumer and small-business disputes.

5. Buildings versus plant, machinery and contents

Buildings

The building figure is generally based on reconstruction of the physical property rather than acquisition of another existing property.

Current statutory compliance, foundations, building services, external works, complex demolition, adjacent-property constraints and listed/conservation requirements can make reinstatement cost very different from both historic construction cost and market value.

Plant and machinery

For replacement-as-new cover, the appropriate starting point is normally the cost of obtaining a new identical or suitable modern equivalent, plus relevant:

freight, duties and exchange-rate exposure;
installation, foundations and dedicated civil works;
connections to power, gas, water, drainage or process services;
commissioning and testing;
consultants’ fees; and
dismantling or debris-removal costs where insured.

Age-based depreciation should not automatically be imported from accounts or a market valuation. AXA’s example is a second-hand machine bought for £3,000 but costing £25,000 new: under replacement-cost cover, the relevant insurance amount is £25,000. Different reasoning applies if the policy expressly settles on indemnity, second-hand value or actual cash value.

The completeness of the population is often as important as unit cost. Contents may extend from major equipment to furniture, IT hardware, tools and low-value items in aggregate, but definitions, sub-limits and exclusions vary.

Stock, vehicles, money, software/data, tenants’ property and third-party assets may be treated separately, so report categories should reconcile directly with the policy definitions and schedule.

6. Concise illustrative example

Assumptions only — not a universal rate or valuation:

An owner-occupied industrial property has an assessed market value of £2.4m, reflecting its land, location, existing building, demand and transaction circumstances.

Its insurance assessment is:

Declared-value component	Illustrative amount
Building reconstruction	£3,250,000
Insured external works/services	£300,000
Demolition and debris removal	£325,000
Professional and statutory fees	£581,250
Day One declared value	£4,456,250

Assume VAT is fully recoverable and therefore excluded, and the policy applies a 20% inflation provision. The illustrative policy sum insured would be:

£4,456,250 × 1.20 = £5,347,500.

If the insured incorrectly declared the £2.4m market value, it would represent only about 53.9% of the correct Day One declared value. Under a straightforward proportional-average clause, a valid £600,000 partial-damage claim could consequently be reduced to approximately £323,000, leaving a shortfall of approximately £277,000, before considering the deductible or other policy limitations.

The reverse can also occur: a modest building on a highly valuable redevelopment site may have a market value well above its rebuilding cost because market value captures land and alternative-use potential, whereas the buildings declared value is concerned with reinstating the insured physical assets.

Practical takeaways

Check the purpose of any report.

A building RCA or declared value is not the same as market value.

Check the exact policy basis.

Confirm Day One, replacement-as-new, indemnity, ACV or another settlement basis.

Confirm the scope and inclusions.

Verify buildings, landlord/tenant fixtures, plant, contents, externals, third-party assets and exclusions.

Are associated costs shown separately?

Rebuild/replacement, demolition/debris, fees, statutory compliance and VAT treatment should be transparent.

Separate declared value from sum insured.

Confirm whether inflation is excluded from the reported figure and who determines the uplift.

Does the report include the reinstatement period?

This can materially inform the inflation provision and also be useful when determining appropriate coverage for business interruption.

Avoid accounting shortcuts.

Historic cost, book value, purchase price and market value are not substitutes for a policy-aligned insurance assessment.

Check that insurance policy definitions, average conditions, VAT and inflation treatment align with the report.
