Hi, just seen that you can load £249 on a gas card and £250 on a key, but what is the max you can have on the meter on each? Say I want to have £500 gas credit built up for winter can we do this..... Ie load £249 and put on meter, then back to shop and put on another £249 and then put the card back in the meter to have a balance of £498 plus anything that was left on the meter to start with?
Thanks
