I just had 5 units installed at my house by airway group. The complete service was brilliant from start to finish. Julian for the initial design, planning followed by installation exactly as per schedule by the best team in the world. The team was led by Jacob with Mark working alongside throughout the entire installation with great support from Paul (electrics) and also Toby on day 1 installation. The work on the roof was exceptional by Jacob with help from Mark. The team was very polite, kept well to the timings, kept me informed at all times and went the extra mile to make sure the place was kept tidy and even touched up any decorating required. Great installation and Highly Highly recommended in what was a complex job.
