Invoicing is mainly handled by the contract partner of HSY.
This also applies to situations, where the person paying the invoice is a tenant, if a written user agreement has not been compiled with the tenant with a written agreement from the lessor.
We send 4 to 6 invoices annually for the household water.
We send the invoices and the annual reading requests for water meter to the address you have reported us. If the recipient (such as a property manager or an accounting firm) of the invoice or meter reading card changes, please notify our customer services of the matter. Remember to also report your meter reading when you report changes.
Before you report the meter reading to us, you will only receive estimated invoices, which are based on the previously reported meter reading. Read more about reporting the water meter reading here.
Estimated average water consumption is around 50 cubic metres per person annually.
As a new customer, we will invoice you based on this estimate until your report your meter reading to us. Based on the meter reading, we will change the estimate of annual consumption as necessary.
Balancing and estimation invoice
When you have reported your meter reading to us, we will send you a balancing and estimation invoice. The balancing and estimation invoices show the previous and current meter readings you have reported.
Through the balancing and estimation invoice, we charge you for your actual water consumption. Based on this, the payments made through the estimated invoices will be deducted from the charged sum.
In addition to this, we also charge the first annual part based on this new meter reading on this same invoice.
The possible difference is either charged though a balancing and estimation invoice or reimbursed back to you.
The balancing and estimation invoice is based on the assumption that previously due invoices have been paid. If previously due invoices have been left unpaid, they need to be paid in addition to the balancing and estimation invoice.
