Please can you forward my thanks to your engineers that stayed on last night to fix our fibre break at Coryton. Thanks to your engineers we were all back up and running after a major outage causing significant loss of equipment on the M4.


Overall, the ERH experience has been first rate. Engineers have a first-class knowledge of the system and its components. Reaction to faults has generally been above what would have been expected.
