Sustainability Advice (label optimization)
Improvement advice examines measures that could achieve a better energy label and more WWS points for your rental dwelling. You receive an official energy label, BBMI measurement report and Label A advice report from €600 excl. VAT; advice does not guarantee a label improvement.

What is included?
- Official energy label
- BBMI measurement report
- Label A advisory report
Why this service?
- Insight into measures and their effect on the label
- Link between sustainability and rental potential
- Official energy label and measurement report included
Process and delivery
- Request: confirm property type, service and available documents.
- On-site survey: a certified expert records measurements and relevant facilities.
- Assessment: check the energy records, areas and applicable points rules for the assignment.
- Delivery: report within 5 working days after the survey; discuss the findings and next steps.
For private investors, portfolios and managers
Private investors can substantiate one or several dwellings before letting. Professional investors can compare property-level data across a portfolio. Owners’ associations and managers can coordinate surveys and documentation; the assessment remains specific to each dwelling.
Combining energy label, measurement and points
Energy Label + Points Assessment combines all three in one survey from €300 excl. VAT, including NEN 2580/BBMI. WWS Advice also includes advice. A standalone points assessment from €220 excl. VAT includes BBMI reporting without a new label. Use the package matching the evidence and advice you need; no fixed saving is promised.

Worked example — fictional dwelling
A fictional detached 220 m² dwelling costs €600 + €50 detached surcharge + 2 × €25 area surcharge = €700 excl. VAT. For a single-family dwelling, F to C adds 22 − (−9) = 31 energy points, provided the new label is actually achieved.
What can improvements deliver?
For a single-family dwelling, F to C adds 31 energy points. A fictional total moving from 120 to 151 has ceilings of €774.94 and €987.78. This scenario guarantees neither the label nor an increase in existing rent.
