As of 1 January 2026, Dutch offices of 100 m² or more need at least energy label C. Annual service-charge settlements are due within six months of year end. Tenants can reclaim overpayments with statutory interest when evidence is missing. Keep EPA reports, retrofit invoices, CBS figures, HVAC logs, and smart-meter privacy notices ready for inspection.
As of 1 January 2026 any Dutch office ≥100 m² must have at least energy label C. Municipal inspectors increasingly ask for retrofit plans, HVAC logs, and the service-charge breakdown in one sitting. Use this guide to keep your dossier airtight.
At a glance
- Label C+ mandatory for offices ≥100 m² (Environment & Planning Act)
- Service-charge settlements due within six months of year end
- Retrofit invoices + CBS index figures must be available digitally
- Tenants may reclaim overpayments with statutory interest
- HVAC maintenance logs + calibration certificates requested most
- Municipal spot checks now include GDPR questions about smart meters
1. Audit your current label status
Collect EPA-U/EPA-W reports, commissioning certificates, and high-resolution photos of insulation, glazing, and HVAC upgrades. Flag assets below label C and rank them by lease expiry so you can plan works before renewals.
Keep both the PDF label report and the XML data in your document management system. Inspectors increasingly ask for the raw XML file to verify authenticity.
- Create a spreadsheet linking each building to its label expiry date.
- Add columns for square meters, tenants, major systems, and planned retrofit budget.
- Share the spreadsheet with property management, finance, and legal so everyone works off the same numbers.
2. Build a retrofit and financing roadmap
Decide which measures you will implement (LED, insulation, solar, HVAC balancing) and how they will be financed. For regulated units, only pass on costs that demonstrably benefit the tenant.
Document the split between capital expenditure (for amortization) and operating expenditure (for direct settlement). When you explain this split inside the yearly service-charge letter, tenants are far less likely to escalate.
3. Service-charge settlement anatomy
Every settlement letter should show: previous advances, actual spend, difference, and whether you are issuing a refund or collecting arrears. Attach a schedule of invoices for energy, cleaning, security, sustainability projects, and explain any CBS indexation.
| Line item | Evidence | Notes |
|---|---|---|
| Energy | Utility invoices + smart-meter exports | Show kWh trend vs previous year |
| Retrofit surcharge | Invoices + calculation of tenant share | Only for measures that benefit tenant |
| Management fee | Lease clause | Cap at agreed percentage |
4. Handling tenant objections
When tenants challenge a charge, reply within 10 business days and attach the invoice, CBS index figure, and relevant lease clause. Offer to walk them through the numbers on a call; many disputes stem from misunderstanding the methodology.
For social-housing tenants, remind them that the Huurcommissie will request the exact same documents, so you are simply accelerating the process.
5. Inspection-ready documentation
Store maintenance logs, meter-calibration proofs, privacy notices for smart meters, and your remediation roadmap in one folder. Municipal inspectors increasingly ask how you safeguard tenant data collected by sensors.
Create a one-page cheat sheet listing where each document lives (SharePoint path, document owner, last update). Train reception and security teams to direct inspectors to the right contact immediately.
6. When to involve a tenancy lawyer
Energy-label duties and service-charge disputes often overlap with Dutch tenancy law, especially when tenants challenge what can be passed through the settlement or when lease clauses are unclear. If you need help assessing your position or matching with a Dutch tenancy lawyer, use the contact options beside this guide.
Frequently asked questions
Can I pass retrofit costs to tenants?
Yes, when leases allow it and the tenant benefits. Break out the cost, expected savings, and the amortization period inside the letter.
What if my label expires mid-lease?
Schedule a fresh audit at least six months prior and notify tenants about any site access required. Keep temporary mitigation steps (for example portable HVAC) documented.
Do smart meters need tenant consent?
Provide a GDPR notice that explains what data is captured, retention period, and who can access it. Consent is not required for billing data but transparency is.
How detailed should the settlement letter be?
Include totals per line item, the method of allocation (per m², per tenant), and whether you applied indexation. Attach supporting invoices for any unusual amounts.
Which documents do inspectors request most?
EPA report, HVAC maintenance logs, Legionella certificates, privacy notices for sensors, and the service-charge calculation workbook.
