Change in household size

How many people live in your home? Where water is shared out per person, that number decides your share: when it changes, tell us with a form.

Why it matters

Your share depends on who lives in your home

With per-person charging the cost of water is split according to how many people live in each home, and not by usage alone. Your allowance — the amount of water at the base rate that you are entitled to — changes with the number of people in the household.

When to tell us

A birth, a child moving out, someone new moving in: every time the number of people in the home changes, up or down.

What changes on your bill

The usage bands are updated to the new number of people: with the right details you pay the right rate, no more and no less.

Only residents count

As things stand, only people who are officially resident in the home count towards the size of the household.

How to do it

One form, two minutes

  • Fill in the Change in household size form — in Italian it is called Comunicazione componenti residenti e/o non residenti. You will find it on the forms page.
  • Send it by email to variazionecomponenti@lirabo.com.
  • The change applies from your next bill after you tell us: the sooner you let us know, the sooner you see it.

The form is a PDF, and it is in Italian only. Write to us at variazionecomponenti@lirabo.com and we will help you fill it in.

Tell us as soon as it happens. The number of people officially resident is also used for the yearly recalculation of the usage bands that the rules on rates require.
