NI Energy Advice: The Northern Ireland Advice Line

NI Energy Advice is Northern Ireland's named household energy advice service. It offers independent and impartial energy advice to domestic householders in Northern Ireland, plus referrals to energy grants and other sources of help¹. It is funded by the Department for Communities and delivered by the Housing Executive, which is also Northern Ireland's Strategic Housing Authority and Home Energy Conservation Authority².

The service is free to the householder and open to all households across Northern Ireland. The Housing Executive states directly that you do not need to be a Housing Executive tenant to use it². That matters, because several of the grant schemes the service refers people to do exclude social housing tenants, so the advice line and the schemes it points to have different eligibility rules.

Contact is by freephone on 0800 111 4455, open 9am to 5pm Monday to Friday, or by email at nienergyadvice@nihe.gov.uk³. The same number and address appear across the Housing Executive's own pages, the Affordable Warmth Scheme contact details and the scheme listings published by the Utility Regulator, so a single call or message reaches both the advice function and the grant enquiry route.

What NI Energy Advice is and who it is for

The service describes itself in a single sentence that appears, near identically, across the nidirect guidance pages on heating technologies, biomass, energy saving grants, insulation and hydropower: it offers independent and impartial energy advice to domestic householders in Northern Ireland, plus referrals to energy grants and other sources of help¹. The repetition is not accidental. Those pages are the ones a householder lands on when searching for a specific technology, and each one routes the reader back to the same advice line rather than to a supplier.

The audience is defined by tenure and geography rather than by income or by housing type. The Housing Executive states that NI Energy Advice is for all households across Northern Ireland², and the same service is described elsewhere as giving free, independent and impartial energy advice to all domestic householders in Northern Ireland⁹. Owner-occupiers, private tenants and housing association tenants all fall inside that description.

The distinction that catches people out is between the advice service and the schemes it refers to. The advice line is universal. The grant schemes are not. The Affordable Warmth Scheme, for example, is not available for tenants living in social housing, and a Housing Executive or housing association tenant is not eligible for it⁴. The Efficiency Plus fully funded insulation scheme carries the same exclusion, stating that Housing Executive tenants are not eligible³. A householder can therefore get advice from the service while being ineligible for the specific grant discussed, and an adviser is the right person to say which route fits.

Free and impartial: what those two words commit the service to

The Housing Executive's own wording is short: "Our advice is free and impartial"². Free means there is no charge to the householder for the advice, and the funding comes from the Department for Communities rather than from a fee or a commission². Impartial means the adviser is not selling a boiler, an insulation contract or an energy tariff, and has no commercial interest in which measure a household chooses.

That is a meaningful distinction in a market where advice often arrives attached to a quote. It is also a limited one. Impartial advice is not the same as a survey, a specification or a warranty, and it does not bind any grant scheme's decision. The service advises on eligibility and routes; the scheme administrator decides the award.

The same free and impartial framing is used by comparable services elsewhere, which helps show what the standard means in practice. The Welsh Government's Nest Warm Homes Programme describes advisers offering free impartial advice to help lower energy bills and improve health and wellbeing¹⁰. National Energy Action, which works across England, Wales and Northern Ireland, provides free advice about energy bills and keeping warm and safe at home, plus benefits advice and income maximisation¹¹. The Energy Saving Trust points households towards free energy advice and support¹².

For a household, the practical test is what the adviser can and cannot do. They can explain a scheme's rules, check a household against them, and refer on. They cannot install, certify or guarantee. Where a household wants a specification for a heat pump or solar array, that is a separate professional step, and official guidance is explicit that homeowners should seek independent advice on solar panels, heat pumps and other energy efficiency measures¹³.

What the service covers: grants, heating, bills and damp

The published topic list is broader than the name suggests. It runs to energy grants and support; heating and energy use; energy bills and fuel poverty support; damp, condensation and ventilation; insulation and home improvements; renewable energy; changing electricity or gas supplier; and heating-oil savings². Each of those is a distinct conversation, and several of them matter more in Northern Ireland than in the rest of the UK because of the housing stock and the fuel mix.

• Energy grants and support
• Heating and energy use
• Energy bills and fuel poverty support
• Damp, condensation and ventilation
• Insulation and home improvements
• Renewable energy
• Changing electricity or gas supplier
• Heating-oil savings

Heating oil is the clearest example of why the local list differs. The Home Heating Oil Support Scheme is open to households who use oil as their primary source of heating, are resident in Northern Ireland, and, in either of the qualifying months, are in receipt of a qualifying benefit, or are a single person or couple, including pensioners, with an annual income of less than £30,000 net of allowable deductions¹⁴. A household on oil with a low income has a route that does not exist in most of Great Britain, and the advice line is the entry point to it.

Damp and condensation is treated as an energy topic rather than a repairs topic, which is the correct framing. Moisture condenses on cold surfaces, so insulation, heating and ventilation are the levers. The service lists damp, condensation and ventilation together², and nidirect publishes separate guidance on ventilation systems for households working through the same problem¹⁵.

On bills, the service covers fuel poverty support and switching supplier². The Consumer Council offers an energy price comparison tool to compare electricity and gas tariffs for all suppliers in Northern Ireland¹⁶, and energy suppliers themselves refer customers who are struggling to pay bills to organisations like Advice NI, which offers free, independent debt advice¹⁶. The advice line sits alongside those routes rather than replacing them.

Referrals to energy grants and other sources of help

The referral function is written into the service's own description on every nidirect page that mentions it¹. In practice that means an adviser can point a household to a named scheme and explain what it requires, rather than leaving the household to work through the scheme rules alone.

The schemes in scope are substantial. The Northern Ireland Sustainable Energy Programme is the main funding mechanism, and the Energy Saving Trust administers it, with a published contact address for the programme¹⁷. The 2026-27 list of schemes names the individual measures and the organisations that deliver them³:

The 2024-25 republication of the same list gives the same contact pattern and the same freephone number for the advice service¹⁸.

The advice line also signposts the Northern Ireland Renewable Heat Incentive, whose guidance documents run to two volumes²⁰, and the support available for generating your own electricity¹³. For households considering low carbon heating, nidirect publishes a separate guidance page on the options⁹.

Two limits are worth stating. First, the service refers; it does not award. Second, eligibility varies sharply between schemes. The Better Energy Homes Plus scheme requires an owner occupier, is available throughout Northern Ireland, and sets income thresholds of less than £28,000 gross for a single person household and less than £35,000 gross for a couple or a joint or single parent family³. The Priority PV Scheme is narrower still: Northern Ireland Housing Executive tenants only, outside a natural gas area, in a single storey Housing Executive property with oil or electric heating, and with income or pension below £35,000 gross for a couple or single parent family³. A household that does not match those conditions is not out of options, but the route changes.

Who is eligible: householders across Northern Ireland, not just Housing Executive tenants

The single most common misunderstanding about the service is that it belongs to the Housing Executive's tenants. It does not. The Housing Executive states that you do not need to be a Housing Executive tenant², and that the service is for all households across Northern Ireland². The delivery body and the eligible audience are different things.

That matters because the tenure rules of the grant schemes are genuinely restrictive, and a householder who assumes the advice line shares those rules may never call. The Affordable Warmth Scheme excludes tenants living in social housing⁴. The Efficiency Plus fully funded insulation scheme states that Housing Executive tenants are not eligible³. Meanwhile the insulation schemes funded by NISEP list owner occupier as the tenure for at least one measure¹⁸, and the Better Energy Homes Plus scheme requires an owner occupier³.

Private tenants have their own conditions. Under the Energy Company Obligation, a privately rented house must have an energy efficiency rating of E, F or G to be eligible, and the owner's permission is required²¹. That is a different test from the owner-occupier income thresholds, and it is the kind of detail an adviser can check quickly.

The service also sits within a wider advice landscape that is not confined to Northern Ireland. National Energy Action offers advice and support to help people across England, Wales and Northern Ireland stay warm and manage energy costs²², and its Warm and Safe Homes advice service provides advice on energy bills, keeping warm and safe, benefits and income maximisation²³. Comparable local authority services in Great Britain, such as Winter Wellbeing in Cornwall and the East Herts Home Energy Support Service, cover grants, eligibility checking, benefits support, supplier switching, energy saving advice, debt advice and referral to other organisations or contractors²⁴. The Northern Ireland service is narrower in geography and broader in scheme knowledge.

How the service is funded and run

The funding and delivery split is stated in one line: the NI Energy Advice Service is funded by the Department for Communities and delivered by the Housing Executive². The Housing Executive's role is not incidental. It is Northern Ireland's Strategic Housing Authority and Home Energy Conservation Authority², which is why the advice line sits inside it rather than inside a consumer body or a charity.

The service has been described in the same terms since at least 2023. A Department for Communities news item from September 2023 describes the NI Energy Advice Line Service as providing free, comprehensive advice and support on how to save energy in the home and eligibility for help to improve energy efficiency²⁶, and a June 2023 item uses near identical wording¹⁷. The continuity is useful: the service has not changed hands or changed purpose across that period.

The Housing Executive also manages the Energy Advice Line and provides advice on all energy efficiency schemes¹⁷. That is a wider remit than the household advice function alone, and it explains why the same freephone number appears in scheme listings published by the Utility Regulator as well as on the Housing Executive's own pages³.

For a household thinking about energy independence, the funding model is the relevant fact. The advice is paid for by a government department, not by a supplier, an installer or a manufacturer, so there is no commercial route by which the advice could tilt towards a particular product. The dependence that remains is a dependence on a public service continuing to be funded, and on the schemes it refers to continuing to exist. Both are outside the householder's control.

How to get in touch: phone and email

The freephone number is 0800 111 4455, open 9am to 5pm Monday to Friday³. The same number appears as 0800 111 44 55 on the Affordable Warmth Scheme page⁴ and as 0800 111 4455 freephone on the Housing Executive's energy pages². The 2024-25 NISEP scheme list gives the same number¹⁸, and the Utility Regulator's news item on that list repeats it¹⁹. The formatting varies; the number does not.

1. Call freephone 0800 111 4455, 9am to 5pm Monday to Friday³.
2. Or email nienergyadvice@nihe.gov.uk².
3. Include the property's address, its heating fuel and the household's circumstances to shorten the exchange.

The email address is used for general energy advice and for Affordable Warmth Scheme enquiries alike, so a single message can cover both.

Two other routes are worth knowing. The Energy Saving Trust administers the Northern Ireland Sustainable Energy Programme and can be contacted about it directly¹⁷. The NI Housing Executive's Home Energy Saving Tool notes that there may be energy grant help to allow a household to make changes²⁷, which is a way to check a property before calling.

For households whose problem is a billing dispute rather than a grant question, the Energy Ombudsman publishes advice for consumers worried about their energy bills²⁸ and guidance on billing explanations²⁹. Those sit outside the advice line's remit, and an adviser will say so.

Where the service stops

The advice line is a signposting and eligibility service, and its limits follow from that. It does not survey a property, specify a system, install anything or certify work. It does not decide grant awards. It does not resolve a dispute with a supplier, which is the Ombudsman's role²⁸. And it cannot change the underlying position of a household that is off the gas network, on oil, and dependent on a delivered fuel whose price moves with the international market.

What it does is remove the information barrier. A householder in Northern Ireland trying to work out whether they qualify for insulation funding, how to reduce a bill, or what to do about condensation has one freephone number and one email address that reach a funded, non-commercial adviser with knowledge of the specific schemes that operate in Northern Ireland. That is a smaller thing than energy independence, but it is the step before it, and it costs nothing to take.

For the wider picture of where advice fits into a plan, free home energy advice in Northern Ireland covers the other services operating in the same space, and checking what grant help you can get before you start work sets out how to sequence a grant application against the work itself. The getting started guide places both in the order a household would normally tackle them.
