Energy bills: Man shares cutbacks that save him up to £550 a year – ‘It pays the bills’

Therefore, a property owner can realistically expect to make a saving of around 45 percent on their water bills.

The average UK roof collects enough rainwater to fill an average of 450 water butts per year.

If people then use this collected water throughout the year for their domestic garden appliances, and to flush the toilet, they’re still going to be making savings.

For example, using a hosepipe in the garden costs on average, £1.50 an hour- by using the water for this alone individuals could potentially be saving hundreds of pounds per year, depending on their usage.
