If you are sitting on lots of credit with your energy supplier due to months of (over)estimated usage, does anyone know if there is a standardised process to follow to have it refunded - is it as simple as giving the energy company a meter reading, then requesting a refund via customer services?
Also does anyone know if there is a penalty free option to pay for exactly what you use on a monthly basis, rather than an averaged/estimated direct debit? I've seen it discussed (I can't recall the exact term) but also hinted at it actually costing more per unit to pay for exactly what you use.
