Priority Services in Northern Ireland: The Customer Care Register

Northern Ireland does not use the Priority Services Register that covers Great Britain. Instead, Northern Ireland Electricity Networks (NIE Networks) runs its own Customer Care Register, and a separate Medical Customer Care Register for customers dependent on life supporting equipment. Both are free to join, both are held by the network operator rather than by an electricity supplier, and both work on the same principle: the operator holds your contact details and your needs, so that when the power goes off it knows who you are and what is at stake.

Registration is by phone on 03457 643 643, online, by WhatsApp or Facebook Live Chat, or by downloading a form and returning it by post¹. Registered customers get their calls given priority during a power cut, regular telephone updates while the supply is off, and at least three days' notice before a planned interruption, with the expected duration¹. The Medical Customer Care Register currently holds 27,000 properties out of the 966,000 properties connected to the NIE Networks distribution system, and crews can be asked to prioritise restoration to those addresses².

What the register does not do is supply power. NIE Networks states plainly that it will not provide a generator for a property during severe weather events², and households on the Medical Customer Care Register are not exempt from planned emergency power cuts if a national rota is ever used³. Registration buys information and priority, not independence. That distinction matters for any household whose health depends on mains electricity.

Who qualifies: medical equipment, age and vulnerability

The NIE Networks Customer Care Register is aimed at households where a power cut is more than an inconvenience. Customers who have medical equipment in their homes, such as specialised mattresses, feeding systems or lifting equipment, can register¹. The parallel Medical Customer Care Register is for customers who rely on electricity for their health needs, described elsewhere by NIE Networks as customers dependent on life supporting medical equipment⁶.

Alongside the network operator's registers sit the supplier-held Customer Care Registers. Every electricity and gas supplier in Northern Ireland must keep a Customer Care Register recording the details and special needs of customers who are of pensionable age, disabled (by virtue of being blind, partially sighted, deaf or hearing impaired) or chronically sick⁵. The Utility Regulator's code of practice for consumers in vulnerable circumstances confirms that electricity suppliers, gas suppliers and NI Water all hold Customer Care Registers, while NIE Networks holds a Medical Care Register for those who rely on electricity for healthcare needs⁸. Joining is a choice the consumer makes: each supplier register stores details of consumers who merit special treatment on account of age, disability or chronic illness, and consumers have to opt in⁹.

The equipment the registers are built around includes oxygen concentrators, patient vital signs monitoring systems and home dialysis⁵. The common thread across NIE Networks and NI Water is consumers who rely on electrical equipment or on a water supply for their day to day care⁵.

For comparison, the Great Britain Priority Services Register admits people who rely on electricity for medical reasons, use a stair lift, hoist or electric bed, have a specific communication need, or would find an unexpected power cut particularly distressing or difficult to cope with¹⁰. The Northern Ireland registers are described more narrowly around medical dependence and the statutory age, disability and chronic illness categories. Further detail on the GB scheme is set out on the Priority Services Register page.

What registered customers get during a power cut

The core benefit is communication. Registered customers can receive up to date information by phone during a power cut or a planned interruption to the supply¹. NIE Networks states that it will then contact the customer regularly during the power cut with up to date information¹¹, and the Consumer Council describes the same arrangement: adding details to the register allows NI Water and NIE Networks to prioritise your contact details if your supply goes off⁵.

Call handling is the second benefit.

In practice the caller either speaks directly to a call advisor or, if all advisors are busy, receives a call back¹¹. For the Medical Customer Care Register, NIE Networks recognises the registered phone number when the customer calls, which supports more accurate estimated restoration times as well as prioritised restoration².

None of this is a supply guarantee. The wider guaranteed standards apply to registered and unregistered customers alike: NIE Networks states it will restore electricity within 24 hours of a power cut, and its overall standards commit to restoring all customers within 24 hours where the cause is a fault on the distribution system¹². Compensation claims under those standards must be made within one month of the day of the interruption¹⁴. The detail is covered on power cut compensation in Northern Ireland.

Planned interruptions: at least three days' notice

Where NIE Networks needs to switch off supply for planned work, registered customers are contacted at least three days beforehand and told the expected duration of the interruption¹. The three day period is not a courtesy confined to the register: NIE Networks gives a minimum of three days' notice before turning off electricity for planned work to any customer¹⁵, and its guaranteed standards repeat that it will let customers know at least three days before a temporary interruption¹². Which? records the same rule from the customer's side, noting that if supply is turned off for planned reasons you must get three days' notice¹⁷.

What the register adds is the method of contact. On the Big Network Rebuild programme, vulnerable customers receive a text message three days before the interruption plus a notification card in the post, and the dedicated customer service team telephones the number held on the Customer Care Register¹⁸. Three separate channels reduce the chance that a household with a communication need or limited mobility misses the warning altogether.

Notice is the single most useful thing a register can give a medically dependent household, because it converts an emergency into a scheduled event. Three days is enough time to charge a battery back-up, arrange a stay elsewhere, or confirm with a clinical team how equipment should be managed. NIE Networks' own advice to registered customers is to make sure any battery back-up is always fully charged¹¹. Where an interruption arises from a fault rather than planned work, no notice is possible, and that is the gap a household's own backup arrangements have to fill. Options are compared on the backup power pillar page and in essential loads and backup circuits.

If compensation is in question for a planned interruption, the claim deadline is again one month from the day of the interruption¹⁴.

How to apply, and the alternative contact option

There is no single application window and no charge. NIE Networks lists the routes as signing up online, contacting the company via WhatsApp, Facebook Live Chat or the Customer Helpline, or downloading a registration form and returning it by post¹. The Medical Customer Care Register can be joined by registering online¹⁹. The helpline number is 03457 643 643²⁰.

Two details are worth noting when filling in the form. First, the same form can be used to register for the NI Water Customer Care Register, by completing the separate section provided¹. A single submission therefore covers the two utilities that matter most to a household reliant on electrically powered care equipment.

Second, an alternative contact can be named. NIE Networks allows customers to provide details of a relative, neighbour or friend as an alternative contact, to be used if the company is unable to speak with the customer directly¹. During a long outage a landline may be dead and a mobile battery flat, so a nominated third party is often the only way the operator can pass on restoration information. GB operators use the same mechanism under different names, from nominated contacts who can be communicated with on the customer's behalf to carers registering on behalf of the person they care for¹⁰.

Written correspondence, including complaints about how the register has worked, goes to the Customer Relations Manager at NIE Networks, Carn Industrial Estate, Portadown, BT63 5QJ²².

Confidentiality: who can see your information

The register holds health and vulnerability information, and NIE Networks limits access to it.

That is a narrower statement than the GB position, where the regulator has set out a minimum set of customer details that energy companies must share between suppliers and network operators: customer contact name, telephone number and email address where available, address, details of any nominated person, details of any agreed password, and details of the customer's needs²³. In Northern Ireland the NIE Networks register and the supplier-held Customer Care Registers are separate things, and registering with one does not populate the other. A household that wants both the network operator and its supplier to know its circumstances has to tell both.

The one deliberate crossover is NI Water, and that only happens if the customer completes the separate section of the form¹. NIE Networks and NI Water jointly operate registers described by the Consumer Council as a Critical Care Register for consumers who rely on electrical equipment or on a water supply for day to day care⁵.

Historically the NIE Energy customer care register offered a wider bundle of supplier-side services: doorstep services, a password scheme, a special advice scheme, large print bills, Braille bills, provision for customers who are deaf or hard of hearing, and a carers contact²⁴. Those are supplier functions rather than network functions, and they illustrate the split between billing support from a supplier and power cut support from NIE Networks.

The Medical Customer Care Register: 27,000 properties and priority restoration

The Medical Customer Care Register is the sharper of the two registers. It holds 27,000 properties, against 966,000 properties connected to the NIE Networks network². That is a small fraction of the customer base, which is what makes prioritisation workable: if a registered property loses power, NIE Networks can arrange for crews to prioritise getting power back on as quickly as possible².

During a major event the register is used as a restoration input. NIE Networks states that it checks the Medical Care Register to make sure that those who have the greatest need for electricity get it back as quickly as possible²⁵. That sits alongside the general restoration rule that hazardous situations and damage affecting large numbers of customers are given priority²⁶. The two principles can pull in different directions: a single registered farmhouse at the end of a long rural spur will not always be reached before a repair that restores a village, and NIE Networks does not promise otherwise.

The storm machinery behind those promises is substantial. NIE Networks has an Emergency Response Plan which comes into effect when weather forecasts indicate that severe weather is likely, suspending all normal activities and directing resources to Local Incident Centres in the affected areas²⁷. Each area of Northern Ireland has a local incident centre staffed by engineers and administrative staff, with a central control centre co-ordinating restoration and providing up to date information for customers²⁶. For Storm Éowyn, with the plan in effect from 23 January until power was restored to all homes and businesses, NIE Networks expanded its contact centre into a second location in Belfast to increase the number of calls it could receive from people who had lost power²⁷.

Where the register stops: no generators, no exemption from rota cuts

Two limits are stated explicitly, and both matter more than the benefits for a household planning its own resilience.

The second limit concerns planned emergency power cuts. NIE Networks states that residential customers, including those on the NIE Networks Medical Customer Care Register, and businesses without backup generation that are not listed as protected by government, would not be exempt³. Only sites on the government's protected list are excluded. If a rota is ever used, the rota for power cuts is published on the NIE Networks website when a planned emergency power cut starts²⁹. The mechanics are set out in more detail on rota power cuts.

A third limit is one of scope rather than policy. The registers are a communication and restoration priority service run by an electricity network company. They do not address clinical questions about how long a given piece of equipment can run without mains power, they do not replace an agreed plan with a healthcare provider, and they do not cover the fixed wiring inside the property. Where the fault is inside the home, NIE Networks recommends checking the property's trip switches first, and notes that lightning often affects supplies to individual properties or small numbers of properties, so if neighbours are not off the operator may need to be told³⁰.

For a household, the honest summary is that registration removes uncertainty and shortens the queue. It does not remove the dependence on the grid, on NIE Networks as the single distribution operator for Northern Ireland, or on a working telephone to receive the updates.

Preparing for a power cut if you are on the register

NIE Networks publishes a short list of preparations for customers who depend on electricity, and one of them is specific to the register: keep any battery back-up always fully charged¹¹. The rest is general readiness: keep a torch and batteries in the house, know the location of the fuse box, be able to open electric gates, keep an electric vehicle battery charged, and join the medical care register if dependent on electricity for medical equipment³¹.

Food is the other routine concern. NIE Networks' emergency power cut guidance gives between 4 and 6 hours in the fridge and 15 to 24 hours in the freezer, if the doors can be kept closed²⁸. Its general power cut advice is more cautious in tone, saying contents should be safe for many hours but that food should be disposed of if there is any doubt it appears to have defrosted³². Figures published by other operators are shorter, so the NIE Networks numbers should be read as the upper end of what a sealed appliance will hold. The subject is expanded on power cut food safety.

A short order of actions when the power goes:

1. Check the property's trip switches, and whether neighbouring properties are also off³⁰.
2. Report the cut through nienetworks.co.uk, Powercheck, WhatsApp, Facebook or the helpline on 03457 643 643⁴.
3. Keep fridge and freezer doors shut³².
4. If lines are down or causing significant risk to the public, call 999³³.
5. If power is not restored within an hour of a scheduled restoration time, check Power Check and report the cut again²⁹.

Updates during a large event are published on the NIE Networks website and social media channels as well as being telephoned to registered customers³⁴. If a generator is used, NIE Networks advises care over siting it because of the risk of carbon monoxide poisoning, and that there should be plenty of air flow³¹. That is covered further on generator safety, and the equipment options for keeping a small medical load running are compared on portable power stations.

What this means for a household's independence

The Customer Care Register and the Medical Customer Care Register make a household better informed during an outage and, in the medical case, earlier in the restoration queue. They change nothing about the underlying dependence. Every registered property still relies on a single distribution network, on NIE Networks' crews reaching a fault, and on a phone line or mobile signal to receive the updates that are the register's main product. NIE Networks transports electricity to over 910,000 customers including homes, businesses and farms²⁸, and during a widespread storm the register's 27,000 medical properties² will still be competing with repairs that restore whole communities first.

Registration is free, it is reversible, and it costs a household nothing but the time to complete a form that also covers NI Water¹. Genuine independence during a cut, whether for a feeding pump, an oxygen concentrator or simply a warm room, comes from equipment the household owns and keeps charged. The register tells you how long the wait will be; it does not shorten the wait to zero. Households comparing the arrangements across the UK will find the differences set out on power cuts in Northern Ireland and on who fixes a power cut.
