Nothing wrong with the outcome or the equipment... which we are very happy with. I found the business process that administers the installation very frustrating and inefficient; BP Chargemaster insist on progressing all the pre-installation work/discussions remotely via their call centre (sending pictures, technical discussions on the pros and cons of different wiring configurations etc.) rather than allow their installation man (who was excellent) to visit the property and agree the scope/nature of the installation face to face. A 15 minute visit in advance of the actual installation would have saved me a lot of time and stress. To be clear this feedback is for the people responsible for the business process to encourage them to introduce some flexibility! All the people who I interacted with were curious and helpful; and the installation man was excellent.
