> Energy declarations in Mölndal are a legal requirement for all residential properties. Learn what you need to know as a tenant or landlord about requirements, costs, and how it affects your housing search in 2026.

## What is an energy declaration in Mölndal?

An energy declaration in Mölndal is an official document that classifies a property's energy efficiency. Every apartment, villa, and rental property in Mölndal must have a current energy declaration to be rented out or sold. The document shows how much energy the building consumes and assigns it an energy rating from A (very efficient) to G (low efficiency).

The energy declaration is not just a recommendation — it is a legal requirement under EU directives and Swedish environmental legislation. Both landlords and property owners must ensure this documentation is current and available to potential tenants and buyers.

## Legal requirements for energy declarations 2026

From 2026 onwards, stricter rules apply to energy declarations in Sweden. All rental properties and privately owned homes must have a valid energy declaration. For landlords, this means the documentation must be presented before a lease is signed.

Boverket is the authority that oversees compliance with energy declaration requirements. According to Boverket, energy declarations must be updated regularly, especially if major renovations have been carried out. Tenants have the right to request to see the energy declaration before signing a lease.

Penalties for not having a valid energy declaration can be significant. Landlords who violate the requirements risk fines and may have their lease contracts questioned. It is therefore important to take this seriously.

## Energy declaration for apartments — what is included?

An energy declaration for an apartment in Mölndal contains several important components:

- **Energy rating**: A value from A to G showing energy efficiency
- **Annual energy consumption**: Estimated annual energy cost
- **Building properties**: Insulation, heating system, ventilation, and windows
- **Recommendations for improvements**: Concrete measures to reduce energy consumption
- **Certification date**: When the declaration was issued and when it expires

For an apartment, the heating system, insulation, and ventilation typically have the greatest impact on the energy rating. Modern apartments with heat pumps and good insulation often receive ratings A or B, while older apartments may fall into the D–F range.

## Energy declaration for villas in Mölndal — special aspects

Energy declarations for villas in Mölndal differ somewhat from apartments because villas often have greater control over their heating systems. A villa can often achieve better energy ratings through installation of solar panels, heat pumps, or pellet stoves.

Villas in Mölndal built before 1980 often have poorer energy ratings due to older insulation and heating systems. Many villa owners invest in energy efficiency measures to improve their rating and reduce long-term energy costs.

A villa with an energy rating of A or B is often more attractive on the rental and sales market, which can positively affect both rental price and resale value.

## Energy declaration costs in Mölndal — what does it cost?

Energy declaration costs in Mölndal vary depending on who performs the declaration and the type of property. Typical costs are:

- **Apartment**: 1,500–2,500 SEK
- **Villa**: 2,000–3,500 SEK
- **Larger multi-family buildings**: 3,000–5,000 SEK

The cost typically covers an energy consultant who visits the property, measures insulation, inspects the heating system, and performs calculations. The price may vary between different certified energy consultants in Mölndal.

As a tenant, it is usually the landlord who pays for the energy declaration. As a villa owner, you can either do this yourself or delegate it to a property consultant.

## How to interpret the energy rating

The energy rating from A to G is simple to understand:

- **A–B**: Very energy efficient — low operating costs
- **C–D**: Average energy efficiency — normal operating costs
- **E–F**: Low energy efficiency — high operating costs
- **G**: Very low energy efficiency — very high operating costs

An apartment or villa with a rating of A can save 30–50% in energy costs compared to a property with a rating of G. This is an important factor to consider when searching for housing in Mölndal, especially given rising energy prices.

## Recommendations for energy improvements

The energy declaration always includes recommendations for how the property can become more energy efficient. Common measures include:

- Switch to a heat pump
- Improve insulation in walls and roof
- Install new energy-efficient windows
- Switch to LED lighting
- Install solar panels (especially for villas)
- Improve the ventilation system

Many of these measures can provide long-term savings on energy costs and increase the property's value.

## Common questions about energy declarations in Mölndal

### How long is an energy declaration valid?

An energy declaration is valid for 10 years from the date of issue. After that, a new declaration must be made. If major renovations have been carried out, it may be appropriate to update the declaration earlier.

### Can I influence my energy rating as a tenant?

As a tenant, you can influence energy consumption by using heat and electricity sparingly, but the energy rating itself is determined by the building's physical properties. However, you can discuss energy improvements with your landlord.

### Is an energy declaration mandatory to rent out an apartment?

Yes, according to law, every rental property in Mölndal must have a valid energy declaration. The landlord must present this before the tenant signs the contract.

### Which energy consultant should I choose in Mölndal?

Choose a certified energy consultant registered with the appropriate authority. Compare prices and read reviews before making your choice.

### Does the energy rating affect the rental price?

Yes, properties with high energy ratings (A–C) can often command higher rental prices, but this is not always the case. The rental price is determined by many factors, but low energy costs are an advantage for the tenant.
