The following letter was sent to the residents of the Curnock Estate on the 20th August 2013. The same date that the works were carried out.
The same problem was also present with the old boilers and it is interesting to find out the reasons for that. Especially after the £500,000 investment in the new equipment. The original document can be found on this link.
On 18th August 2013 there was a power cut that might has affected the boilers. A few hours later there was no hot water on the whole estate.
The repairs team was informed on the same day. Unfortunately "the number of contractors present on that day were not enough to fix the major failure" according to the repairs team.
