Good to know

EPC certificate for a triplex in Brussels: what you need to know

🏛️ What is a triplex?

A triplex is a home spread over three levels connected by one or more internal staircases. This layout is often found in renovated Brussels townhouses or converted upscale buildings.

From an EPC standpoint, a triplex requires a full inspection of each level: insulation, window frames, heating, and often the roof if the top level is there.

📄 Documents to prepare

  • Floor plans for all three levels
  • Deed of sale (year of construction)
  • Insulation works invoices, roof as a priority
  • Boiler certificate
  • Window frame replacement invoices

⏱ A longer, more technical visit

With three levels to inspect, a triplex visit generally lasts 90 to 100 minutes. The auditor must measure each room, check insulation on every floor and photograph all relevant façades.

💡 How to improve your score?

For a triplex, the priority measures are:

  • Roof insulation (upper level)
  • Wall insulation on exposed levels
  • Replacing window frames on all three floors
  • Condensing boiler or heat pump

💡 Did you know? A triplex often comes from a Brussels townhouse divided across several levels. Original architectural features (ceiling height, large windows) can significantly influence the EPC calculation.

Frequently asked questions

FAQ — EPC Certificate for a Triplex in Brussels

Does a triplex cost more than a duplex to certify?
Yes, because of the extra level to inspect, the visit is longer (90-100 min vs 60-75 min) and the price slightly higher, generally starting at €295.
Is a triplex common in Brussels?
Yes, particularly in renovated and subdivided townhouses, or in some upscale buildings with units spread over several floors. It's a layout we come across regularly.
Do I need to give access to every level during the visit?
Yes, absolutely. The auditor needs access to all three levels in full to produce an accurate certificate. Any inaccessible space will be assessed using less favourable default values.
My triplex has a roof terrace, is that taken into account?
The terrace itself isn't included in the heated floor area calculation, but the insulation of the roof slab beneath the terrace is an important part of the EPC calculation.
