"The site contact who oversaw the work last night said that the Carter Sullivan engineers were “the best he’s ever seen”. They removed all of the old UPS equipment and batteries and took back all of the packaging materials leaving both comms rooms in a 'very tidy state'."
- DWP Lincoln
"Site called and asked if you could pass on his comments to the engineers – efficient, extremely polite, clean and tidy, appreciated them wearing masks at all times, he really was genuinely pleased with the way they worked."
