The assignment should explain the purpose, valuation date and recipient, then connect evidence about permitted use, lease and income, floor area, condition, energy performance, legal rights and market comparables. If this is your situation, use the steps below to decide which facts and questions matter for you. If you are valuing business premises, keep local market evidence such as [property valuation in Beste Taxateur Inoost, Amsterdam](https://taxateuramsterdam.com/nl/kennisbank/beste-taxateur-in-amsterdam-oost) separate from the building's commercial use, lease and income. When the report arrives, compare its purpose, date and evidence with [reading a valuation report](/en/guides/how-to-read-a-valuation-report/). The [NRVT's commercial valuation standards](https://www.nrvt.nl/voor-register-taxateurs/regelgeving/praktijkhandreiking-bedrijfsmatig-vastgoed/18) treats assignment, data, methods, reporting and uncertainty as connected parts of professional work. The report should make its assumptions reviewable. Energy performance is one relevant input. The [RVO guidance on energy label C for offices](https://www.rvo.nl/onderwerpen/wetten-en-regels-gebouwen/energielabel-c-kantoren) says an office generally needs at least label C, subject to exceptions. RVO's 1 July 2026 snapshot reported 84% of registered office floor area at C or better, 4% at D to G and 12% without a label in the cited register view. That is a dated register snapshot, not a national price premium or a prediction of an individual office's value. Prepare the report in this order: 1. Define purpose, value basis, date and recipient. 2. Confirm legal use, floor areas and planning constraints. 3. Assemble lease, rent, occupancy, condition and energy evidence. 4. Compare relevant office rents, sales and investment evidence. 5. Review method choice, assumptions, sensitivity and uncertainty. ## Does this situation match your question? If you are an owner, buyer, lender, landlord, tenant, investor or adviser dealing with an office building or office component in the Netherlands. It is useful for a sale, purchase, financing, refinancing, accounting, lease decision or feasibility review. If you are valuing an industrial building, define [industrial property valuation](/en/guides/industrial-property-valuation/) around its use, condition and market evidence. It does not value a specific property. A commercial valuer must define the assignment and assess the evidence. Energy, planning, tax and legal questions may need input from other specialists. If you are valuing a commercial property, define [commercial property valuation](/en/guides/commercial-property-valuation/) around its use, income and physical evidence. ## Context: an office is a use, income and building question Two offices with the same area can have different value because their locations, leases, tenants, vacancy, fit-out, floor efficiency, planning permissions, energy condition and capital needs differ. A rent per square metre is evidence, not a complete value formula. If you are valuing an industrial building, define [industrial property valuation](/en/guides/industrial-property-valuation/) around its use, condition and market evidence. Energy information can affect compliance, operating costs, tenant demand and future investment. The [Rijksoverheid utility-building guidance](https://www.rijksoverheid.nl/themas/klimaat-milieu-en-natuur/energielabel-woningen-en-gebouwen/energielabel-utiliteitsbouw) describes general label obligations at sale, rent and completion, alongside exceptions. A label must be checked against the actual building and current rules. The body visual shows an office evidence stack. It helps the reader see why energy evidence should be reviewed with lease, use, floor plan and market information rather than treated as a standalone price adjustment. As you prepare for a valuation, gather [documents needed for a property valuation](/en/guides/documents-needed-for-property-valuation/) before the inspection takes place. ![Office valuation evidence stack connecting use, lease, floor area, energy and market context](/images/articles/office-property-valuation/body-visual.webp) ## Office valuation evidence to assemble
Assignment
Record purpose, value basis, valuation date, report recipient, assumptions and required format.
Use and planning
Provide permitted use, current use, floor plans, areas, permits, split functions and any planning restriction.
Lease and income
Share leases, rent roll, indexation, incentives, service charges, break rights, vacancies, arrears and tenant information where relevant.
Building condition
Collect maintenance records, installations, fit-out, defects, planned capital works, asbestos information and accessibility details.
Energy
Provide the current label, underlying certificate, energy systems, improvement plans and evidence of any exception that is being relied on.
Market evidence
Ask which comparable rents, sales, yields or other references are relevant and why their date and quality fit the assignment.
## Constraints that can change office value ### Permitted use is not the same as actual use An office may be occupied in a way that differs from its legal permission. Confirm the planning position and identify the consequences for income, adaptation or future use. ### The lease can move the result Term, indexation, incentives, break options, service charges and tenant strength affect income evidence. A passing rent may differ from a market rent, and a vacant building does not have the same risk profile as a stable lease. ### Energy label is an input, not a score The RVO rule and exceptions matter for compliance. The label can also inform operating cost and investment questions. It does not create an automatic value uplift or replace building inspection, lease evidence and comparable data. ### Floor area needs a definition Net, gross, lettable and ancillary areas can be measured differently. Use a consistent measurement basis and explain what is included, especially in multi-tenant or mixed-use buildings. ## The office valuation process in six steps ### 1. Define the decision State whether the report supports a sale, purchase, loan, accounting, lease or feasibility question. Name the recipient and required date. ### 2. Verify use and rights Check ownership, planning, permitted office use, floor areas, easements, leasehold and restrictions. Flag a mismatch between actual occupation and legal permission. ### 3. Build the income file Prepare leases, rent roll, indexation, incentives, vacancies, service charges, arrears and operating costs. Mark estimates and missing documents clearly. ### 4. Inspect condition and energy Provide the label and certificate, then connect them to installations, maintenance, fit-out, defects and planned works. A certificate is evidence; it is not a substitute for inspecting the building's condition. ### 5. Compare market evidence and methods Ask how comparable rents, sales and income assumptions are selected. The report should explain method fit, reference dates, adjustments and uncertainty. ### 6. Review the report against the brief Check areas, use, lease figures, label, assumptions, value basis, date and recipient. ## Four office-property situations ### Fully leased investment office Income and lease terms may dominate the evidence. Test passing rent, market rent, breaks, incentives and tenant risk rather than using one headline rent. ### Vacant or partly vacant office The plan must address marketing time, fit-out, incentives, vacancy costs and the evidence for achievable rent. A vacant building can have higher uncertainty than a stable lease. ### Office with a label or compliance issue Confirm the label, exceptions and improvement obligations. Separate compliance cost from the market effect of better operating performance. ### Office combined with another use Split the areas, rights, income and planning evidence. ## Mistakes that weaken an office valuation ### Using one rent per square metre **Why it happens:** it is an easy comparison. **Fix:** explain area basis, lease terms, incentives, condition and location before comparing. ### Treating label C as a value guarantee **Why it happens:** a compliance threshold looks like a quality score. **Fix:** use energy as one input alongside operating cost, investment needs, demand and building condition. ### Ignoring the actual use **Why it happens:** the word “office” appears in the documents. **Fix:** check permitted and current use, ancillary spaces and any mixed-use rights. ### Hiding capital expenditure **Why it happens:** maintenance plans are kept separate from the valuation brief. **Fix:** give the valuer known works, budgets, condition reports and installation records. ## Aftercare: check changes after the report Keep the final report with the leases, energy certificate, plans and maintenance file used in the assignment. Revisit it when a tenant leaves, a lease is renegotiated, a label changes, a major installation fails or planning permission changes. If a future decision has a different purpose or value date, ask whether a new assignment is required. An old office valuation should not be reused automatically after material income, use or condition changes. ## Frequently asked questions ### Does every office need an energy label C? RVO guidance says offices generally need at least label C, subject to exceptions. Check the current official rule against the building's function, size, status and any exception rather than assuming the result. ### Does an energy label determine office value? No. It is relevant evidence about compliance, operating performance and future work. Lease, location, use, condition, income and market data can have a larger effect. ### What documents does an office valuer need? Usually the brief, ownership and planning information, floor plans, leases, rent roll, service charges, condition and maintenance records, energy evidence, permits and relevant market information. The exact file depends on purpose. ### Is a rental indication enough for an office valuation? It can support an early conversation, but it is not automatically a complete report for a lender, buyer or accounting purpose. Confirm the scope and recipient. ### Can a vacant office be valued like a leased office? The physical building may be the same, while income, vacancy, incentives and marketing risk differ. The assignment must reflect the actual occupancy situation. ## Office valuation checklist - [ ] Purpose, value basis, date and recipient are written down. - [ ] Permitted and current use, floor areas and planning constraints are checked. - [ ] Leases, rent roll, indexation, incentives, vacancies and service charges are provided. - [ ] Condition, maintenance, fit-out, installations and planned works are documented. - [ ] Energy label, certificate and any claimed exception are checked. - [ ] Relevant rent, sale and income evidence is identified with dates. - [ ] Method choice, assumptions and uncertainty are reviewable in the report.
