Invoices and payment

We recommend that our customers enable e-invoices or make a direct payment agreement with their bank. If you are a personal customer, you can also select an email invoice. Otherwise, we will issue water and waste bills as paper invoices.

We have renewed our invoicing system, which means that the agreement numbers and reference numbers have changed. Please pay attention to the changes when ordering an e-invoice from your online bank or changing the information on the current e-invoice.

• The new agreement number, i.e. the reference number, of the water bill starts with 33.
• The new agreement number, i.e. the reference number, of the waste management invoice starts with 34.

E-invoice for consumers

You will receive e-invoices directly to your online bank. The payment details are ready on the e-invoice, so you do not have to enter them yourself in the online bank. To receive e-invoices, sign an agreement with your bank. To log in to online banking, you need the personal online banking credentials issued by your bank.

Select a biller based on the contents of the invoice

• Waste bills: Helsinki Region Environmental Services Authority
• Water bills: Helsinki Region Environmental Services Authority HSY (WATER SERVICES)

To order an e-invoice, you need the reference number that is in the bank transfer section of your invoice. Place an e-invoice order in your online bank for all the water contracts and waste services that you would like. Your order is contract and waste service specific.

Electronic invoice for companies, communities or housing companies

Companies can pay their invoices by electronic invoice if they use a system that accepts electronic invoices.

Invoicing rhythm of waste and water invoicing

You will receive an invoice once every three months if you are a personal customer. Housing companies, communities and companies receive an invoice every month.

We will send an invoice when the amount of the invoice exceeds 50 euros, however, at least once a year. Exceptions to this are final invoices, separately billable services and water services meter reading invoices.

Invoicing based on water consumption

If you only want water supply invoices based on meter reading, please report your property’s water meter reading to us once a month. This way your water consumption becomes a balancing invoice without an estimate. You can report the water meter reading on an electronic form.

Please note that it is not necessary for you to provide a water meter reading every month. You can wait for a reading request from us.

Waste and water invoice reference number

In future, the reference number of the invoices sent by HSY will be the same for all invoices for the same waste service order and water contract. Y

our payments will be directed primarily to the oldest open invoice for the waste service or water contract. This way you will avoid additional payment reminder and interest costs.

An example of how invoice payment is targeted

In the example below, you have three unpaid invoices because of an unreported change of address. All of the invoices are related to one waste management service or water contract.

The outstanding balance of the unpaid invoices is EUR 140. The amount of the refund invoice that applies to the oldest unpaid invoice of EUR 40 is EUR -10.

Refunds

As a general rule, we take into account any refunds for a water or waste bill on the customer’s next invoice. In some cases, we may pay the refund in cash. Such situations include, for example, the termination of a waste or water contract, duplicate payment or some other significant overpayment.

We do not apply refunds of waste charges to water rates or refunds of water rates to waste charges. Please note that the waste or water bill refund is specific to the waste service and contract. 

You can provide your account number for refunds using the online form. To submit the form, you will need the credit note number, invoice number, and the water contract number or your waste management customer number. Both numbers are entered in the contract number field on the form.
