Energy Renovation Done Right, First Time
Energy renovation is the highest-impact renovation a homeowner can do in 2026. Energy costs are higher than they were in the early 2020s, and energy-label requirements for rental and resale are tightening. Our energy renovation service handles cavity wall and roof insulation, floor insulation, triple-glazed window replacement, mechanical ventilation with heat recovery, heat pump install and solar-ready electrical preparation. We typically lift an energy label from G or F up to B or A and cut heating bills by 40 to 70 percent. Most energy renovations finish in three to six weeks and qualify for subsidies in NL (ISDE), BE (Mijn Verbouwpremie) and DE (KfW Foerderung).

Frequently Asked Energy Renovation Questions
How long does an energy renovation take?
Most energy renovations run three to six weeks depending on scope. Insulation only can be one to two weeks. Full label upgrade with heat pump and ventilation is closer to five weeks.
How much does an energy renovation cost?
Energy renovations typically start at around 12,000 euro for cavity wall and roof insulation. Full label upgrade with heat pump and ventilation can reach 40,000 to 60,000 euro. Subsidies typically cover 20 to 40 percent.
Which subsidies apply?
In the Netherlands the ISDE subsidie covers heat pumps and insulation. In Belgium Mijn Verbouwpremie covers insulation, ventilation and heat pumps. In Germany KfW Foerderung covers single measures and full retrofits. We map every applicable subsidy in your quotation.
Will I really lift my energy label?
Yes. A typical 1970s detached home at energy label G can reach label B with roof + wall + floor insulation, triple glazing and a heat pump. We model the expected label outcome before any work begins.
Will a heat pump work in my older home?
Yes, with proper insulation. Heat pumps deliver lower water temperatures than gas boilers so insulation has to come first. We design the package as one system.
Can I do this in phases over multiple years?
Yes. Many homeowners do roof and wall insulation first, then heat pump and ventilation 12 months later. We design the phasing so each step works on its own and prepares for the next.
