Energy renovation: comfort, savings and grants in 2026

An energy renovation gives you two things at once: a lower energy bill and a home that feels comfortable all year round. But the order in which you tackle the work makes a world of difference.

We are happy to share the approach that delivers the most in practice.

Start with the envelope, not the technology

The biggest mistake is investing in an expensive heating system while the heat escapes through the roof and the walls. So tackle the envelope of the home first. A well-insulated home then needs a much smaller, more efficient heating system.

The right order of an energy renovation

In practice, we follow this logic:

• Insulate the roof and attic floor: often the fastest gain.
• Insulate the walls and floor: comfort you feel right away.
• Replace the glazing: high-performance glass keeps the heat inside.
• Airtightness and ventilation: prevent heat loss and moisture problems.
• Renew the heating: an efficient system such as a heat pump.
• Solar panels: generate yourself what you consume.

Do not forget ventilation

The more airtight a home, the more important good ventilation becomes. Otherwise damp, used air lingers, leading to condensation and an unhealthy indoor climate. So insulation and ventilation always go together.

Our tip: do not see ventilation as an extra, but as a fixed part of every energy renovation.

Comfort you feel right away

An energy renovation is not only about the numbers on a bill. No more cold walls, no more draughts, an even temperature in every room: that comfort you notice every single day.

And the grants?

Many energy measures are supported by grants via Mijn VerbouwPremie. The amounts and conditions did change in 2026, however, and depend on your income category.

Note: always check your situation on the official Mijn VerbouwPremie website or via Premiezoeker.be, as the rules are adjusted regularly.

Does an energy renovation pay for itself?

In the long run, usually yes. You save on your bill every month, your EPC label improves and the value of your home rises. And that is without even counting the comfort you gain every day.

Frequently asked questions about energy renovation

In what order should I best tackle an energy renovation?

Start with the envelope of the home: insulate first (roof, walls, floor), then the glazing and ventilation, and only after that the heating and possibly solar panels.

Do I need ventilation after insulating?

Yes. The more airtight the home, the more important good ventilation is to avoid moisture and an unhealthy indoor climate.

Does an energy renovation pay for itself?

In the long run, usually yes, through a lower bill, a better EPC label and a higher property value, on top of the daily comfort.
