the review and updates were updates were good in the lead up to the installation. My installation was booked for between 12 and 3 and engineer called me at 1455 to tell me he was 5 minutes away. He arrived at 1510 which was outside the agreed window and of course it then took almost two hours to complete the installation. Whilst I acknowledge that timings may change on the day, it would have been good if someone let me know in advance or even on the day that the engineer was going to be a bit late. Overall, I'm happy with the installation and the knowledge of your engineer.
