This amazing offer isn't for one day only, does not require a code, and customers don't need to be the first in the virtual queue to bag this life-changing opportunity.
Customers of the water company just simply have to follow a few easy steps to save those precious pounds.
By taking a four-minute shower, rather than a bath, customers could save around 40L of water each time, knocking around £12.87 off an average annual bill per person.
Or, by turning off the tap instead of leaving it to run whilst brushing their teeth, customers could save nine litres of water a year - saving a family of four £57.80 per year.
Over 200L of water is wasted per day by leaky loos, but if customers opt to have this repaired for free with Northumbrian Water as part of the Leaky Loo initiative, they could save up to £200 on their bill.
Alternatively, customers have the option to request for a water meter to be installed, which can also save money depending on how much water is used.
Tim Wagstaff, Lead Water Efficiency Manager at Northumbrian Water, said: "By making these tiny changes to their daily routine, our customers could save a lot of money on their bill.
"Not only would these things save on costs, but also save energy - which is also incredibly important for our environment."
Another way that customers could save money, is by making the switch from bottled water to tap water - and the water company work hard to ensure that customers receive clean, clear and great tasting water straight into their homes.
To demonstrate the difference in value:
If residents used shop-bought bottled water to fill an average-sized bath, it could cost roughly £52 - as opposed to just 17p in tap water.
Similarly, if bottled water was used to wash clothes, it could cost on average around £39 per cycle.
Tim added: "Realistically the general public would not use bottled water for these types of every-day uses - so why drink it instead of tap water.
"We treat our tap water so that it tastes fantastic, and there are a number of health benefits associated with drinking tap over bottled.
"Also, when our customers drink straight from the tap, they know that they are contributing to the fight against single-use plastics."
