Learn how an energy label and home improvements can inform a Dutch residential valuation, with current label coverage, market evidence and careful calculations. ## When this valuation matters If you are valuing a home, treat its energy label as one piece of the valuation rather than a price tag. Homeowners, buyers, sellers, lenders and advisers can understand how energy performance, running costs, condition and local market evidence come together. ## TL;DR The energy label can inform a valuation through expected energy use, comfort, condition and buyer demand. The effect depends on the property, market and evidence, so the label should be read with improvements, defects and comparable sales. Rijksoverheid says most homes need a valid label for sale, rental or delivery, and that labels are valid for ten years. RVO’s 2025 monitor recorded 5.6 million definitive labels, equal to 68% of the Dutch housing stock on 1 January 2025. Kadaster research found useful market associations, yet the study also shows why the label should be read with the rest of the property evidence.

Keep that purpose in view as the details come in; each one matters because it changes what the appraiser needs to test. An energy label is one input; for a home near Eindhoven, compare [property evidence from Nuenen](https://taxatieeindhoven.com/property-valuation-nuenen/) with the label so location, condition and comparable evidence stay in the same valuation context. ## What the label tells you The Dutch label scale runs from A++++ to G. Rijksoverheid explains that the label helps a buyer or tenant see the home’s energy performance and possible improvement direction. It also indicates whether the home is prepared for lower-gas or gas-free heating options under the label’s assumptions. The label is evidence of a recorded assessment at a point in time. It does not show every behaviour that drives a household’s bill. Occupancy, thermostat settings, weather, energy prices and installation use can change actual consumption. Kadaster’s recent research makes the same practical point: a label does not give a complete picture of energy costs. The label can also expire. Check the issue date and validity before using it in a sale or valuation file. If the home has new insulation, glazing, a heat pump or solar panels, gather certificates, invoices and specifications rather than relying on a planned-work description. ## What current data says about coverage RVO’s Monitor of the Built Environment 2025 reported 5.6 million homes with a definitive registered energy label on 1 January 2025. That represented 68% of the housing stock. The monitor extrapolated that 74% of the stock had label C or better, which is an estimate for the wider stock rather than a count of definitive labels. The figures help explain why a valuer may need to check both the label and the physical evidence. A home without a current registered label can still have insulation or energy-saving installations. A label on its own does not prove that every feature remains in the same condition. ## What Kadaster and CBS found Kadaster published a regression analysis based on home sales from 2022 through the third quarter of 2025, combined with CBS figures about annual energy use. After accounting for other characteristics, the research reported: - homes with label B had an average purchase price 2.1% below homes with label A or better; - homes with label G had an average purchase price 18.9% below homes with label A or better; - homes with solar panels had an average purchase price 4% higher; - homes with a heat pump had a purchase price almost 4% higher than homes with district heating in the analysis. These are modelled associations in a defined dataset. They are not a price list for labels. Kadaster also says location, floor area, property type and build year have the largest effects on the sale price. An A label in a less sought-after location does not receive a universal premium because of the letter alone. ### A percentage calculation with a warning label Suppose a home sells for €480,000. Applying the reported 18.9% difference as pure arithmetic gives €480,000 × 0.189 = €90,720. That calculation shows the size of a percentage on a large base. It does not predict that changing a particular home from G to A would add €90,720. The study compares groups and controls for several factors; renovation cost, local demand, layout and timing still matter. Good preparation keeps a missing document from becoming a late surprise. ## How a valuer can use the evidence Bring four kinds of evidence: 1. **Label record:** issue date, label class and registered document. 2. **Physical features:** glazing, insulation, ventilation, heating, solar panels and metering. 3. **Financial evidence:** invoices, specifications, grants, maintenance records and actual bills where relevant. 4. **Market evidence:** comparable homes with similar location, type, size, age and energy features. The valuer can then explain which feature is present, which source supports it and how it fits the comparable evidence. Property valuation documents make the supporting file complete and traceable. ## For sellers Order or locate the current label before setting the information pack. Record completed improvements with dates and invoices. Separate work that is finished from work that is planned. If a sale falls near the value date of a previous report, tell the provider what changed since that report. Avoid advertising a fixed price increase from an energy improvement unless a specific, well-supported analysis justifies it. The Kadaster numbers describe average associations across a dataset. A local valuer should assess the home and comparable evidence. ## For buyers Ask for the label, issue date and evidence behind any claimed improvement. Compare estimated energy use with the actual condition and the costs of future work. A low label can signal a larger improvement budget. A high label can still leave questions about ventilation, maintenance or future replacement. When an energy discussion is mixed with a statutory value or a mortgage valuation, keep market value and WOZ value as a separate question. ## Keep three decisions separate ### Sale or mortgage value The energy feature can be part of a market-value opinion. The report still needs a purpose, date and comparable evidence. ### Actual household cost The label gives standardised information. Household behaviour, energy prices and equipment use determine the actual bill. ### Renovation return An improvement can reduce use, improve comfort and affect buyer preference. Its sale-price effect depends on the home and market. Keep energy savings, maintenance and value analysis as separate calculations. With the label and the physical evidence together, you can give the valuer a brief that matches the decision you need to make. These are the details worth checking before you compare providers or send the file. ## Next steps Check the label date, collect physical and financial evidence, and write a short list of completed and planned work. Give the same information to the valuer and lender when a mortgage is involved. Residential property valuation places the label evidence alongside location, condition and comparable transactions. Use these questions to test whether the proposed work fits your situation. ## FAQ ### Does an A label guarantee a higher valuation? No. Kadaster research found average differences between label groups after accounting for other features. A valuer still assesses location, size, type, age, condition and comparable sales. ### How long is an energy label valid? Rijksoverheid says an energy label is valid for ten years. Check the issue date and current record before using it. ### Can energy improvements be added to the value euro for euro? There is no general euro-for-euro rule. The market response, quality of the work, remaining life, running costs, local demand and comparable evidence affect the analysis.
