Changing the amount of emergancy credit on has card

Hi how do i change the amount of emergancy on my gas card from £10 to £5

You can’t. Emergency credit is a fixed amount unusual to see someone bucking the trend most people want more

It was on the leaflet that got sent to me when i changed companies you can change it somehow

Yes because different companies all offer a different amount of emergency credit the only way to change it would be to change supplier or have someone come out and reprogram the meter

The only conceivable way would be to phone bulb and ask them if they could make you a special one off card that was programmed to only allow you £5 emergency credit
