Five steps to a more sustainable home
Personal advice
Everything starts with a good conversation. We visit you and take the time to understand your situation, wishes and future plans. This forms the basis for advice that is truly right for you.
Customized sustainability plan
After the consultation, we work out a complete quotation: you will receive a customized sustainability plan including savings, costs and expansion possibilities.
Expert installation
A worry-free installation is paramount. Our technicians work neatly and safely and explain how the system works. We keep appointments and ensure proper completion.
Live insight through the app
In our user-friendly app, you can see exactly how much energy you are generating and consuming. This allows you to keep a grip on your investment and discover where there are still gains to be made.
Aftercare & support
Even after completion, we remain involved. Our team is ready to answer all your questions. And with a customized service contract, your installation is always in good shape!
Frequently Asked Questions
1. How long will the process take?
From advice to completion, this usually varies between 4 and 8 weeks. This depends on your wishes, the delivery time of products and the planning of our fitters. We always keep you well informed.

The only thing we ask is that the work site is easily accessible. If anything is needed, we will let you know well in advance.
3. Is someone coming by for recording?
Yes. One of our staff will visit you to take stock of the situation. That way, we can be sure that the system is a perfect fit for your home and needs.

Our team of certified technicians will come by on the appointed day. We work quickly, neatly and safely. Usually your system is functioning within one day. Then we calmly explain how everything works.
