The Energy Performance Certificate (EPC) is a mandatory document that indicates how much energy your home consumes. The result is a label from A+ (very efficient) to F (very poor) and a score in kWh per square meter per year. The EPC is required when selling or renting.
The score is not measured based on your actual consumption, but calculated based on building characteristics: insulation quality, heating system type, glazing, ventilation and any renewable energy sources.
Uw dak- en muurisolatie en schrijnwerk bepalen samen meer dan 75% van uw EPC-score.
Up to 30% of heat escapes through a poorly insulated roof. Roof insulation is often the most cost-effective first step.
Uninsulated exterior walls cause major heat losses and thermal bridges that create moisture problems.
Single glazing or outdated profiles let a lot of heat escape. Triple glazing can reduce loss by 80%.
An outdated boiler uses up to 40% more energy than a modern heat pump or condensing boiler.
Controlled ventilation with heat recovery (system D) saves energy and improves air quality.
The EPC label indicates how much energy your home uses per square meter per year. The lower the number, the more efficient and comfortable your home.
Average. Room for improvement, especially in roof and walls.
Since January 1, 2023, when purchasing a home with label E or F, you are obligated to renovate to at least label D within 6 years. Those who do not comply in time risk a fine of 500 to 5,000 euros.
Fine for non-compliance: 500 to 5,000 euros
The fine does not cancel the obligation. After payment you receive a new deadline.
Renovation obligation applies to homes purchased with label E or F. Deadline: label D within 6 years of purchase.
From 2030, rental properties must meet a minimum EPC label. Non-compliant homes may no longer be rented.
Flanders aims for all homes to reach label A. Renovating becomes increasingly urgent as the deadline approaches.
Not every measure has the same impact. Below you can see per measure how many kWh per square meter your score drops, what it costs and what you save annually.
Roof insulation
-75 kWh/m²The number 1 measure. Up to 30% of all heat disappears through the roof. Can be insulated from both inside and outside.
Exterior wall insulation
-60 kWh/m²Eliminates thermal bridges and drastically improves comfort. With a full facade renovation you combine this with new joinery. Schrijnwerk bekijken
Heat pump
-100 kWh/m²Replaces your old boiler. A heat pump extracts 3 to 4 times more heat from the same amount of energy.
High-performance glass
-35 kWh/m²Modern windows with triple glazing reduce heat loss by up to 80% compared to single glazing.
Ventilation system D
-20 kWh/m²Mechanical ventilation with heat recovery. Recovers up to 95% of heat from extracted air. Meer over ventilatie
Solar panels
-55 kWh/m²Generating your own green electricity lowers your primary energy consumption and improves your EPC score.
Stack multiple measures for the best result. A combined approach lowers your score faster than individual measures.
The Flemish government encourages energy renovation with premiums, favorable loans and fiscal benefits. We guide you through every application.
Additional benefits: 6% VAT (instead of 21%) for homes older than 10 years. Mijn VerbouwLening: interest-free up to 15,000 euros via Fluvius.
Energy costs rise an average of 3% per year. The longer you wait, the more you pay. Below we compare the cumulative energy cost of a home with label F versus the same home after renovation to label B.
After 20 years you save almost 78,000 euros in energy costs. The investment has more than paid for itself.
We guide the entire process: from a thorough home analysis to the execution of all works and the application for your premiums.
Home analysis
An energy expert analyzes your home: insulation, heating, ventilation, glazing. You receive a clear report with priorities.
Renovation plan
Based on the analysis we create a plan with the most effective measures, including cost estimate and premium calculation.
Execution
Our teams carry out the works: insulation, joinery, heating, ventilation. Everything is coordinated so you experience minimal disruption.
New EPC
After completion we have a new EPC drawn up. This confirms your improved label and serves as proof for the renovation obligation.
Premium application
