How it works — from request to certificate

It all starts with your request. You can reach us via the online quote form, by email at [email protected] or by phone at 0475 65 10 05. We respond on average within 4 hours — often even faster. During this initial contact, we discuss the property type (apartment, house, commercial property), the estimated surface area and the reason for the inspection (sale, rental or renovation). Based on this, we immediately provide you with a clear price indication. In our experience, clients appreciate this transparency: you know in advance exactly what it costs, with no hidden fees. We then schedule an appointment at a time that suits you — during the day, in the evening or at the weekend. On average, we can visit within 3 to 5 working days.

On the agreed day, our VEKA-certified energy expert (type A) visits your property. During our inspections, we work according to the official inspection protocol IP2025, which has been in effect since July 2025. Specifically, we measure and check:

• All rooms and their dimensions — floor area, ceiling heights, window and door openings
• Walls, roof and floor — thickness, material and insulation value (U-value)
• Windows and glazing — glass type (single, double, HR++, triple), frame material, airtightness
• Heating system — boiler type, brand, year of manufacture, efficiency, controls (thermostat, thermostatic valves)
• Hot water — production method, storage volume, distribution losses
• Ventilation — ventilation system type (A, B, C or D), grilles and ducts
• Renewable energy — solar panels (Wp), solar boiler, heat pump
• Photo documentation — since IP2025, photographic evidence is mandatory for all insulation and installation measures

In our experience, an inspection takes 1 to 2 hours for an average apartment or terraced house, and 2 to 3 hours for larger homes or villas. Tip: prepare well for your inspection. The more supporting documents you can show (invoices, technical data sheets, plans), the more accurate your EPC score will be. Check our preparation tips for a complete checklist.

After the inspection, we process all data in the official VEKA certification software. This is the only software with which legally valid EPC certificates can be issued in Flanders. Our energy expert accurately enters all measurements, material types and installation characteristics. The software then calculates the primary energy consumption per square metre per year (kWh/m2/year) and assigns an energy label from A+ (very energy efficient) to F (energy guzzler). During our inspections, we double-check every data point to prevent errors. Accurate input is crucial: an error in the insulation value or boiler type can make the difference between label C and label D. We therefore take extra care with this step. Additionally, the software generates personalised recommendations with indicative cost estimates for energy-saving measures, so you know exactly which renovations offer the best return on investment.

Once the calculation is complete, the EPC certificate is submitted to the Energy Performance Database of the Flemish government. You receive the official certificate typically within 24 to 48 hours after the inspection — by email in PDF format. The certificate contains:

• Your energy label (A+ to F) and the characteristic score in kWh/m2/year
• A comparison with similar properties in Flanders
• Personalised recommendations with cost estimates per measure
• Your position relative to the 2050 renovation obligation

Your certificate is valid for 10 years and is automatically linked to your building passport on woningpas.vlaanderen.be. You can use it immediately for the sale or rental of your property.
