Thinking about improving your Dutch energy label before selling or renting? Start by getting a current, registered energy label. It shows exactly where your home stands today and which improvements will have the biggest impact on your rating. That way, you invest in upgrades that really make a difference.
Before you spend a euro: get a current label first. It tells you exactly where you stand and which improvements will actually raise your score — so you invest in the changes that pay off, not the ones that just feel productive.
1. Insulation — the big one
Roof, floor, walls, in that order of impact for most Dutch homes. A house that leaks heat will always score poorly no matter what else you do. Roof and floor insulation are often the most cost-effective first moves, especially in older Randstad houses. This is where the rating moves most.
2. Glazing — from single to HR++
If you still have single glazing or older double glazing, upgrading to HR++ (high-efficiency) glass makes a real difference to both comfort and the label. In many 1930s Hilversum and Amsterdam homes, the windows are the obvious weak point.
3. A more efficient heating system
How you heat your home is a major factor. Moving from an older boiler to a modern high-efficiency (HR) boiler helps; moving to a heat pump — full or hybrid — helps considerably more, because the calculation rewards low-carbon, efficient heating. This is a bigger project, but it's often what pushes a home into the A/B range.
4. Solar panels
Panels generate energy on-site, and the label rewards that directly. For many homes, adding solar is one of the more straightforward ways to lift the rating a level or two, and it pairs naturally with a heat pump.
5. Ventilation and the smaller wins
Efficient (ideally heat-recovery) ventilation, LED lighting throughout, and good hot-water efficiency each nudge the score. Individually small, together meaningful — and usually the cheapest items on the list.
What doesn't improve your Dutch energy label
A fresh coat of paint, new flooring, a smart thermostat on its own, or a beautiful kitchen — lovely for living, largely invisible to the energy calculation. The label measures the building's energy performance, not its style. Spend your improvement budget where the assessment actually looks.
Why a better label is worth the effort
Beyond lower energy bills and a warmer home, a stronger label has real financial upside. An A or B label can qualify you for a mortgage interest discount of around 0.2% with several Dutch banks — roughly €700 a year on a €350,000 mortgage. And when you sell, a better-rated home tends to fetch more and sell faster. The efficiency upgrade often pays you back twice.
The honest bit
Sometimes the jump you're hoping for isn't realistic without a big renovation, and I'll tell you that plainly rather than sell you a dream. After your inspection we'll show you which specific improvements would lift your score and which aren't worth it for your home — so you can decide with clear eyes.
