Your Malta water bill: people, units and billing days

Use cubic metres consumed in the period

One cubic metre is 1,000 litres. If your reading rises from 280 to 298, you have used 18 cubic metres, or 18,000 litres. The calculator takes cubic metres, so enter 18.

Use consumption between the same two dates as your billing period. A daily average can help compare periods of different lengths: 18 cubic metres over 60 days is 0.3 cubic metres a day.

Registered people affect the first band

The residential first band is 33 cubic metres per registered person per year at €1.3965 per cubic metre. Usage above the allowance is €5.1395 per cubic metre. The residential service charge is €59 a year.

REWS specifies proportional charges for periods shorter or longer than a year. A partial-year calculation therefore needs both the service charge and the consumption allowance adjusted, not just the final annual total divided.

A two-person annual example

For two people registered throughout a 365-day year, the first-band allowance is 66 cubic metres. If consumption reaches 80 cubic metres, only the 14 cubic metres above that allowance use the higher rate.

Before comparing the result with an account

Confirm the residential account category and registered occupants. The number of people physically staying at a property may differ from the account record. This calculator cannot verify that record or apply a change for you.

Use your exact billing period and check whether readings are estimated. Credits, previous payments, arrears or corrections can make the amount due different from the cost of consumption in that period.

For a household budget, keep water and electricity as separate estimates, then add them once. If rent already includes utilities, avoid adding the same allowance twice. Use actual bills to update your estimates as soon as you have them.
