Energy regulator Ofgem is investigating gas firm Cadent over its record keeping, after some 1,000 buildings were found to be missing from its gas pipe records.
Ofgem is investigating whether Cadent, formally National Gas Grid Distribution, failed to keep accurate records of its risers (gas pipes in high-rise buildings) and whether it has an appropriate recording system in place now.
The missing records were discovered after a council requested the information following the Grenfell Tower fire last year, the BBC reported. Cadent confirmed it had recorded information about gas pipes in Grenfell Tower in 2016.
Cadent said it alerted Ofgem after it discovered maintenance information on some gas pipes was missing from its digital records. As a result, around 1,000 buildings may have gone unrecorded in its 10-year survey.
The gas company is responsible for pipes in four of the UK’s eight regional distribution networks. It works in the West Midlands, North West, East of England and North London.
A spokesperson for Cadent said: “Between January and February 2018 Cadent identified that just some of our records regarding high-rise buildings - building of six storeys and above - were not contained on our digitised records and were therefore not part of our regular 10 yearly rolling survey programme.
“As a consequence we informed Ofgem at the earliest opportunity in early February and have continued regular progress briefings to date.
“Alongside this we immediately implemented a survey recovery programme to resolve the issue as quickly and effectively as possible. This programme of work will be substantially completed in July 2018.
“Cadent will fully co-operate with Ofgem’s investigation, but at this stage it is not appropriate to comment further.”
