Energy declaration for cabins

What is an energy declaration?

An energy declaration is a document describing a building's energy performance. It shows how much energy the house uses, the heating source and how the building compares to similar ones. The goal is to make energy use transparent to buyers and tenants.

When is a declaration required?

In Sweden an energy declaration is required for the sale or rental of most buildings. For detached homes used as permanent residences it must exist at sale. There are exemptions for cabins — see below.

Validity

An energy declaration is valid for ten years, provided no major changes affect energy performance — such as replacing the heating system, adding insulation or large renovations. If the house has been renovated for energy reasons a new declaration may be needed.

What does the declaration contain?

• Primary energy use (kWh/m² per year)
• Heating type and energy sources
• Ventilation system
• Energy class (A–G)
• Suggested energy efficiency measures
• Certification details and the certified energy expert

Who performs the declaration?

The declaration must be produced by a certified energy expert. You may not do it yourself. The expert visits the property, gathers technical data and registers the declaration in Boverket's register.

Exemptions

Some buildings do not need an energy declaration — for example buildings with very low energy use, buildings intended to be used less than four months per year, detached buildings under 50 m² of usable area and certain culturally protected buildings. Always check current rules with Boverket if unsure.

What does it cost?

The price varies by size, location and complexity. For a typical cabin the cost is usually between 2,000 and 5,000 SEK. It can pay off to request quotes from several certified energy experts.
