I was surprised to learn that there are significant amounts of melatonin present in the gastrointestinal tract.
In 2014 the average dual fuel reached an eye watering Â£1,344. The average electricity bill was Â£592 and the average gas bill was Â£752. But averages can be confusing.

If your home is water efficient then you would be toward the lower end of this scale.
