Your bill and our charges

In this section you can find out more about how to pay your bill, our scheme of charges, reading your meter and leakage allowances.

Non-Domestic Water and Sewerage Charges

NI Water is keeping non-domestic water and sewerage charges at the rate of inflation for 2021/22. The new tariffs are effective from 1 April 2021.

Frequently Asked Questions (FAQs)

These FAQs provide answers to your queries in relation to billing.

Unmeasured Customers

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 2021. Last year, to provide some relief to our business community during the challenging pandemic period, whilst also balancing the needs of NI Water to remain operational, NI Water deferred a planned increase to 2020/21 non-domestic charges until 1 October 2020. The balance (i.e. the charge increase for 1 October 2020 – 31 March 2021) has been carried forward onto your unmeasured bill for 2021/22.

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 2021 – 31 March 2022).

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. 

Metered Customers

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.

Are any discounts available?

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

The hospitality and non-essential retail/services sectors will have experienced a significant reduction in their demand for the water and wastewater services provided by NI Water. As a consequence, billed water and wastewater volumetric charges will be substantially less than under normal trading circumstances resulting in lower value bills.

I’ve had to permanently close my business. Can you arrange a temporary/permanent disconnection of the meter?

I have a leak on my supply which took/is taking longer than normal to get repaired due to the current situation. What will happen to my bill?

NI Water will assess these queries on a case-by-case basis.

Questions Common to both Unmeasured / Metered Customers

Why is NI Water introducing new tariffs at this time?

NI Water is keeping non-domestic water and sewerage charges at the rate of inflation for 2021/22. This means our non-domestic customers will see their bill remain the same as last year in real terms. From 1 April 2021, tariffs for 2021/22 will rise by 0.9% in line with inflation.

NI Water believes it has taken every action possible to alleviate pressure on its business customers while also balancing the needs of the company to remain operational in the current climate. This enables us to strike a balance between minimising the impact of a price increase on customers and ensuring sufficient revenues are generated for NI Water to continue to deliver its essential services.

We know this is a challenging time for everyone and we do not want any business or organisation to feel extra pressure due to their NI Water bill. The decision was taken therefore, with the support of the Minister and Department of Infrastructure and the Utility Regulator, to hold the increase to the rate of inflation.

NI Water understands that any billed amount may prove to be a challenge for some of our non-domestic customers.  We will fully support our customers and continue to work with any customer who finds themselves in financial difficulties.  For any customer impacted by Covid-19, it is important that you contact NI Water as soon as possible by calling our Billing Helpline on 0345 877 0030. We can discuss your circumstances and explore options available to you and come to a suitable and sustainable payment arrangement.

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.

Understanding your bill

Both metered and unmeasured (unmetered) customer bills have a standing charge element. This standing charge is a fixed charge which includes the cost of providing a water supply.

Read your meter

We aim to read your meter at least twice a year. If we haven’t been able to read it when it is time for your bill, we will use an estimate based on your past water use. At least one bill in any 12 month period will be based on an actual read.
