WWS points per energy label: what does each label yield?

The system since the Affordable Rent Act

Before the revision of the housing valuation system, a poor energy label mainly yielded few or no points, but did not actively lower the point count. Since the tightening, this works the other way around: poor labels receive a negative valuation, while good labels yield considerably more points than before.

This particularly affects homes with label E, F or G hard: besides the missed potential of a better label, they also lose points relative to a neutral valuation, which considerably widens the gap with well-insulated homes.

The figures according to current implementation practice

According to the Rent Tribunal's application in early 2026, label E carries a deduction of -4 points. Note: in one place in the text of the underlying regulation, -5 points is mistakenly stated for label E, while the Rent Tribunal in its implementation practice uses -4 points; if in doubt, consult the Rent Tribunal's current policy manuals.

Label D yields +14 points for a single-family home and +11 points for a multi-family home. The difference between label E and label D therefore comes to +18 points for single-family homes and +15 points for multi-family homes. For labels F and G, an even greater deduction applies than for label E, and for labels above D (C, B, A and higher), the points increase further.

• Label E: -4 points (with a differing mention of -5 in the underlying regulation).
• Label D single-family home: +14 points; label D multi-family home: +11 points.
• Jump from E to D: +18 points single-family, +15 points multi-family.
• For exact points for F, G and labels above D: consult the Rent Tribunal's current policy manuals.
