Business energy users in Yorkshire and the north-east have been making emergency calls to their energy supplier during the recent cold snap.
According to the Yorkshire Post, Northern Gas Networks has received an "unprecedented" number of calls to help cheap gas customers with their power and has had to draft in extra engineers.
Director of communications John O'Grady told the newspaper: "The recent cold weather has provoked an unprecedented number of gas emergency calls across the whole of the country, so we have to prioritise on a risk basis the calls we are receiving and naturally those calls which present the greatest risk have to be dealt with first."
He said the energy supplier apologises to users who are currently unable to use its services "but hope people will bear with us while we deal with the backlog".
Meanwhile, the Met Office has warned cheap energy customers and other people in Scotland and Northern Ireland that more snow is expected this week.
