 Trustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ Highly Recommend Encon for Solar Installation We had an 8.8kWh, 20-panel solar system installed by Encon, and the results have been fantastic. Our electricity account is now €562 in credit, and this month alone we received a €192 credit from selling excess energy back to the grid! The service and workmanship from Encon were absolutely first class from start to finish. The team was professional, knowledgeable, and made the whole process easy and stress-free. If you’re considering solar, I can’t recommend Encon highly enough — it’s been one of the best decisions we’ve made!

 Trustindex verifies that the original source of the review is Google. I needed internal roof insulation on an exposed roof/ceiling between the exposed wooden beams. Encon did a marvelous job. They were professional, arrived on the given date and completed on the suggested date. I am very pleased with the work and the house feels so much warmer.
