Why Is My Water Bill So High? How to Check for a Hidden Plumbing Leak

If your latest water bill is much higher than expected, it could be more than just increased household water use. In many cases, a sudden spike in your water bill is caused by a hidden plumbing leak.

While some leaks are easy to spot, others can remain unnoticed for weeks or even months, wasting thousands of litres of water and increasing your utility costs. Identifying the problem early can help prevent unnecessary expenses and avoid more extensive plumbing repairs.

What Causes a High Water Bill?

A higher-than-normal water bill doesn’t always mean your household is using more water.

Some of the most common plumbing-related causes include:

  • Leaking taps
  • Running toilets
  • Underground water leaks
  • Hidden pipe leaks inside walls
  • Faulty hot water systems
  • Outdoor irrigation leaks

Even a small leak can waste a surprising amount of water over time, making early detection important.

How Can You Tell If You Have a Hidden Leak?

Hidden leaks aren’t always obvious, but there are several warning signs to watch for.

These include:

  • An unexplained increase in your water bill
  • Damp patches on walls or ceilings
  • Mould or mildew growth
  • Water stains
  • Reduced water pressure
  • The sound of running water when no taps are in use

If you’ve noticed one or more of these signs, it’s worth arranging a professional inspection before the problem becomes more serious.

What Can You Check Yourself?

Before calling a plumber, there are a few simple checks you can carry out.

Look around your home for dripping taps, leaking toilets or outdoor taps that may not be shutting off properly.

You can also check your water meter. Turn off every tap and water-using appliance in your home, then monitor the meter. If it continues to move, there’s a good chance water is escaping somewhere within your plumbing system.

While these checks can help identify whether a leak exists, they won’t usually reveal exactly where it’s located.
