Non-Domestic Water and Sewerage Charges
Frequently Asked Questions (FAQs)
These FAQs provide answers to your queries in relation to billing.
What sort of repayment options are available?
NI Water will assess payment difficulties on a case-by-case basis. We urge you to contact us on our Billing Line on 0345 877 0030 and we can discuss your circumstances and explore options available to you and come to a suitable, sustainable payment arrangement.
Are any discounts available?
NI Water is unable to offer customers any discounts on our bills.
What NAV is my bill based on?
Unmeasured bills are based on the latest Land & Property Services valuation list, which came into effect on 1 April 2023.
I would prefer to be billed based on metered charges.
Contact us at customer[DOT]billing[AT]niwater[DOT]com and we will investigate if it is possible for a meter to be installed on your supply. If it is possible, you will remain liable for unmeasured charges up until the date the meter is physically installed.
I’m not paying NIW for the full 12 months, I’ll only pay for the months that my business/organisation is open.
Unmeasured annual bills include charges for the full 12 month charging period (1 Apr 2023 – 31 March 2024).
For a property that is not served by a metered connection to the water mains supply, the charging mechanism for services provided to the property are unmeasured water and sewerage charges which consist of a standing charge and a variable charge:
- the standing charge is a ‘fixed charge’ applied to all unmeasured properties; and
- the variable charge is based on the property’s Net Annual Valuation (NAV) as set by Land and Property Services (LPS) and used by NI Water as the basis for your annual bill for water and sewerage services provided to the property.
The standing ‘fixed’ charge component of unmeasured charges covers the fixed costs of maintaining the NI Water supply infrastructure to the property.
Unmeasured charges by their nature can only reflect estimated consumption. Use of a water meter to ensure charges reflect actual consumption remains NI Water’s preferred method of billing non-domestic customers.
The NI Water charging policy for unoccupied unmeasured non-domestic properties (as referenced in the current Scheme of Charges and approved by the Utility Regulator and the Consumer Council NI) is:
10.4 Where a customer is liable to pay unmeasured water and sewerage charges, the charges are payable where a furnished property is connected to water and sewerage services regardless of whether or not services are actually used
I’m unable to pay my latest bill. Will my premises be disconnected?
We urge you to contact us on our Billing Line on 0345 877 0030 and we can discuss your circumstances and explore suitable and sustainable payment options available to you.

There are no discounts available for metered customers, other than the normal domestic allowance and non-return to sewer allowance.

Questions Common to both Unmeasured / Metered Customers
Why is NI Water introducing new tariffs at this time?
We are aware how challenging the environment can be for local businesses within the economy right now. In previous years, we have been able to limit the non-domestic price increase to strike a balance between generating sufficient income and minimising the impact on business customers. Whilst NI Water has again absorbed as much cost as possible, the company is facing significant financial pressures from rising energy prices and other cost increases.
Measured customer bills will rise by 12.7%, while unmeasured and trade effluent bills will rise by 13.7% and 15.5% respectively. This compares favourably with other utilities across Gas and Electricity sectors.
NI Water is mindful of the impact of price rises, it is therefore important that customers who may need extra help with their bill communicate with us as soon as possible. Our billing team will be on hand to offer guidance, including payment breaks or longer repayment plans
We have enhanced our online self-service portal with a smarter navigation to help provide a better experience when paying a bill, managing account(s), or viewing water consumption details
I am no longer responsible for the property. What do I do?
If you have recently vacated the property, please contact us providing evidence such as a proof of sale, or your tenancy agreement. You will remain liable for charges up until the date you vacated the property.
