You apply to Warmtefonds yourself; Soleca neither handles financial details nor intermediates.

Stap voor stap
From a Soleca quotation to your own application
The responsibilities remain deliberately separate, so you know whom to contact at every stage.
Have your project assessed
Soleca measures your property and prepares an itemised quotation for the selected frames, doors and glazing.
Check the measure
Before applying, check that the specification and product values match Warmtefonds' current list of eligible measures.
Apply online yourself
You personally start an application with Nationaal Warmtefonds. Warmtefonds states that an application remains valid for three months.
Provide your documents
You upload your quotation and, if requested, the contractor declaration in Mijn Warmtefonds.
Warmtefonds assesses
Warmtefonds checks your finances and BKR record and may make an offer. You are not obliged to accept it.
Installation and payment
After signing, Warmtefonds opens the building deposit. You submit our invoices yourself; Warmtefonds normally pays them directly.

We had window frames installed by Soleca. We had pleasant contact with Mathis and then had the pleasure of welcoming Willem and Willem to our home for the installation. I would definitely recommend the guys!
Milan Breedveld
After searching for weeks for a company willing to install our window frames at a reasonable price, we finally ended up at Soleca. It was well worth the wait! I was skeptical due to previous experiences with contractors, but that proved unfounded. The window frames were installed very neatly and quickly. I recommend this company to everyone!
Roan Dronrijp
We had window frames and sliding doors installed for our new home in Hellevoetsluis and are extremely satisfied! Everything fits perfectly and is beautifully finished inside. Ultimately, we're very happy we chose Camille and Soleca!

From a quick appointment with good and clear advice to the installation of the window frames. Everything went flawlessly and what craftsmanship! Top service!
Mohammed el Fizazi
We had all the window frames and the front door in our home replaced with uPVC. Everything is beautifully finished, and the installers even hung the curtain rails for us. Very happy, definitely recommended!
Beyza Ustübi
They come by to inspect everything thoroughly, ensuring the quote is accurate from the start and preventing any problems later. Delivery and installation went smoothly and as agreed. The installers were knowledgeable and friendly. All for a reasonable price. Highly recommended.

I received good help from Soleca; there were a few points for improvement, but they resolved these issues skillfully and quickly. All in all, very satisfied.

Can I finance new uPVC frames through Warmtefonds?
Insulating uPVC frames, doors and high-performance glazing are listed as potential measures by Nationaal Warmtefonds. Your project and products must meet its current conditions, and Warmtefonds assesses your application.
Will I automatically receive 0% interest below €60,000?
No. You apply for the standard Energy Saving Loan. Nationaal Warmtefonds then assesses whether your combined taxable income and financial circumstances meet its 0% interest conditions.
Will Soleca apply for the loan for me?
No. You always apply independently and directly to Nationaal Warmtefonds. Soleca supplies only the quotation, product specifications and a contractor declaration if required.
Do I need a quotation first?
Warmtefonds advises obtaining quotations first. You need your quotation when supplying the required documents, and the loan amount cannot exceed the total for approved measures.
Does 0% interest mean the loan is free?
No. If Warmtefonds accepts you for 0% interest, you pay no interest but still repay the full amount monthly. A loan always creates a payment obligation.
