If you pay in instalments, the amount of the instalments will be increased with:

deferral interest not exceeding the reference rate set by the European Central Bank;

default interest established by the Integrated Water Service Regulations only starting from the expiry of the deadline set for payment.

The deferral interest will not be applied if the high amount of the bill is caused by prolonged periods of billing suspension and/or high adjustments deriving from readings with a lower frequency than that which is envisaged, for reasons attributable to us.

If payment by instalments is requested for a previous unpaid amount, or for several bills, you can make the request by indicating the number of proposed instalments and the effective date, bearing in mind that the default interest established by art. 38 of the Integrated Water Service Regulations will be applied to the unpaid amount, as well as the deferral interest in the amount of the legal interest in force plus 2%.
