PEOPLE who use pre-paid gas and electricity meter cards should stock up for Christmas.
British Gas is issuing the advice to help customers avoid being caught out when the card outlets close for the festive period.
A spokesman said: "Customers who use a Key or Smart card or tokens should buy sufficient credit to see them through the festive season.
"Customers should check Christmas and new year hours of the outlets they use, particularly as post offices will be closed for four days at Christmas and three days at new year."
British Gas's 24-hour emergency hotlines will be open throughout Christmas and the new year.
The number for gas escapes is 0800 111 999 and for meters 0845 6066 766. Customers experiencing electricity power cuts should phone British Gas on 0845 7660 111.
