Join the 1KOMMA5° movement

Take the lead in climate protection - hear from our customers on how they are making a difference.

With 1KOMMA5° I found the whole process from start to the finish a very easy experience. From sales to the tradies leaving the home after completion. The office staff always attentive, listening and very helpful. Product is superior.
Chris T.
Coordination between the trades was fautless. The installation went very smoothly, the team were friendly and even placed a pre-existing broken roof tile for me. No tiles were broken by the installation despite the age of the roof.
Sue D.
Used them twice (on different homes). Very happy with their service. They don't deal with cheap string systems so don't even bother if all you're after is a cheap price. If you compare their offering to other vendors in the market, they are quite reasonable.
