With an energy label of A, B, or C, your home is already energy efficient – especially if you have the A rating.
Therefore, this guide is about identifying the final improvement opportunities, turning your home into a showcase of low heating costs and minimal climate footprint.
Let’s get started!
What do you want to renovate?
When planning energy renovations in your home, it’s important to first identify where the greatest potential for improvement lies. In other words, where you can save the most money and reduce the most CO₂. Fortunately, this often go hand in hand!
Here are two ways to identify the biggest improvement opportunities in your home.
Choose the one that makes the most sense for you:
Use your energy label
Since you already have a good energy label, you can follow the recommendations from its report. An energy label is valid for 10 years.
In the report, you’ll find:
– Recommendations for energy improvements
– Estimates of investment costs
– Annual savings in DKK and reduced CO₂ emissions
You can find your energy label here.
Once you’ve decided which renovations to carry out, you can contact a local contractor for an estimate on the job.
New energy label
If your current energy label is close to expiring, you can choose to get a new one. It typically costs between DKK 4,000 and 10,000. The energy label must be issued by a certified energy company, which you can find using SparEnergi’s search tool.
Do your own energy check
You can also choose to carry out your own inspection of your home to identify where it might be smart to make energy renovations.
Morten shares tips on how to do just that in the ProjectZero House.
Once you’ve decided what energy renovations you’d like to carry out, simply contact your local contractor to get a quote for the work.
Tip:
All banks offer green loans for sustainable investments. So if you need help financing the renovations, it’s a good idea to ask your bank about this option.
Use the Craftsman Deduction
Once your energy renovations are completed, you can take advantage of the new craftsman deduction (Håndværkerfradrag), which came into effect on January 1, 2025.
You can get a deduction of DKK 8,600 per person in the household. If two people live together, you can deduct up to DKK 17,200.
See how to apply the deduction below:
What expenses qualify for a craftsman deduction?
The new craftsman deduction focus on climate and environmental improvements.
This means you can get a deduction for things like window replacement, insulation, climate-proofing, and installation of solar panels.
You can only get a deduction for the labor costs – not for materials.
Be aware of...
The work must be paid for digitally – via MobilePay, debit card, or online banking. Cash payments are not eligible for deductions.
Remember to keep the invoices as documentation, and ask the contractor to separate the invoice into materials and labor (excluding VAT).
The work must be carried out by a VAT-registered company in Denmark.
How to apply for the deduction
To get the craftsman deduction, you need to log into Skat TastSelv, click on your preliminary tax assessment (Forskudsopgørelse), and find the craftsman deduction section.

Switch to a more climate-friendly heating source
If your home is heated with oil or gas, there are energy optimizations and CO₂ savings to be made by switching to a greener heating source.
If you have access to district heating in your area, we recommend this solution. If you live outside a district heating area, you can apply for support for an individual heat pump through the heat pump pool.

Repair your household appliances
As a new feature, the service deduction now also covers repairs to large household appliances.
This means you can get a deduction of up to DKK 17,500 for the repair of appliances such as dishwashers and washing machines.
It’s a great opportunity to extend the lifespan of your appliances and promote circularity.
What services qualify for the service deduction?
You can get a deduction for labor costs for services such as cleaning, childcare, and gardening – and now also for the repair of large household appliances.
