FAQ

Energy assessment and renovation planning

Is this an accredited energy audit?

This page describes support for planning renovation work. For a regulated audit or PEB/EPC certificate, verify the professional’s accreditation and your region’s requirements before commissioning it.

What does an assessment cost?

The price depends on the building, available information, visits and requested deliverables. Scope and fees should be confirmed in writing.

Which work should come first?

The order depends on defects, moisture, ventilation and the junctions between different works. It must suit the building; there is no universal ranking.

What savings or grants can I expect?

Savings depend on the building, use, climate and execution. Support depends on current regional rules. Scenarios are neither a savings guarantee nor confirmation of eligibility.
