Are you a homeowner or private tenant in Northern Ireland struggling with high energy bills and a cold home? The Northern Ireland Sustainable Energy Programme, often called the Warm Homes Scheme, may be able to help with significant financial support for energy improvements.
The NI Sustainable Energy Programme offers up to £7,500 in grants for insulation and heat pumps. This is one of the most generous UK-wide schemes per household, but eligibility is strictly means-tested and only for homeowners or private tenants in fuel poverty.

The NI Sustainable Energy Programme offers eligible households up to £7,500 in grants for measures like insulation and heat pumps (NIHE, 2026). This makes it one of the most generous UK-wide schemes per household, compared to an average of around £5,000 for similar means-tested grants across Great Britain.
The NI Sustainable Energy Programme offers up to £7,500 in grants, making it one of the most generous UK-wide schemes per household
The average UK government energy grant across similar schemes is approximately £5,000 in 2026, meaning the NI programme’s maximum of £7,500 represents a significant premium for qualifying households. This programme is administered by the Northern Ireland Housing Executive (NIHE) and funded by the Department for the Economy (DfE) (DfE, 2026).
Grants cover a wide range of measures, from cavity wall and loft insulation to air source heat pumps and boiler replacements. However, eligibility is strictly means-tested, and the scheme is designed specifically to address fuel poverty in the region.
The NI Sustainable Energy Programme is for low-income homeowners and private tenants in fuel poverty
This is the direct answer to the query “who qualifies for the ni sustainable energy programme”. Eligibility is based on household income, receipt of specific benefits, and the property’s Energy Performance Certificate (EPC) rating (NIHE eligibility criteria, 2026).
Homeowners and private tenants (with written landlord permission) are eligible. Social housing tenants are not, as their landlords are responsible for energy upgrades. The property must typically be in a state of disrepair or have a low EPC rating, usually bands E, F, or G.
Qualifying benefits include Pension Credit, Income Support, income-based Jobseeker’s Allowance, income-related Employment and Support Allowance, Universal Credit, and certain other means-tested benefits. If your gross annual household income is under £20,000, you may also qualify even without receiving these benefits.
Quick numbers grant amounts, income thresholds, and EPC requirements
| Measure | Typical Grant Amount (2026) | Income Threshold (Gross Annual Household) | EPC Requirement |
|---|---|---|---|
| Cavity wall insulation | £400 – £800 | Under £20,000 (or on qualifying benefits) | E, F, or G |
| Loft insulation (top-up) | £200 – £500 | Under £20,000 (or on qualifying benefits) | E, F, or G |
| Air source heat pump | £6,500 – £7,500 | Under £20,000 (or on qualifying benefits) | E, F, or G (post-installation target: C) |
| Boiler replacement (gas/oil) | £1,000 – £2,500 | Under £20,000 (or on qualifying benefits) | E, F, or G |

Who is not eligible for the NI Sustainable Energy Programme
Households with a gross annual income over £20,000 (or equivalent benefits status) are excluded from the programme. Social housing tenants living in housing association or NIHE-owned properties are not eligible, as their landlords are responsible for energy upgrades (NIHE eligibility policy, 2026).
Properties with an EPC rating of D or above (A, B, C, or D) are generally ineligible for the main grant, though top-up insulation may be considered in some cases. Homeowners who have already received a grant from the scheme within the last 10 years for the same measure are also excluded.
Private tenants must have their landlord’s written permission before applying. If the landlord refuses, the tenant cannot proceed with the application.
How to verify a certified installer for the NI Sustainable Energy Programme
All work must be completed by an installer registered with the NI Sustainable Energy Programme’s approved contractor list. Installers must hold relevant certifications: Microgeneration Certification Scheme (MCS) for heat pumps and solar thermal, Gas Safe Register for gas boilers, and OFTEC for oil boilers (Gas Safe Register, 2026).
Homeowners can verify an installer’s status by checking the NIHE “Approved Contractors” database online or by calling the NIHE Warm Homes helpline. For insulation, installers must be registered with the National Insulation Association (NIA) or an equivalent NI-approved body (MCS, 2026).
Never pay an installer directly for work under this scheme. The grant is paid directly to the approved installer after the NIHE inspects and signs off the completed work.

The application process a step-by-step outline
Step 1: Check eligibility using the NIHE online eligibility checker or by calling the Warm Homes helpline. This is a quick way to see if you meet the basic income and property criteria.
Step 2: Submit a formal application via the NIHE website or a paper form. You will need to provide proof of income, benefits, and property ownership or tenancy agreement (NIHE “How to Apply”, 2026).
Step 3: The NIHE will arrange a free home energy survey to assess your property and recommend the most suitable energy-saving measures.
Step 4: Once approved, you select an approved installer from the NIHE list. The installer carries out the work to the agreed specification.
Step 5: The grant is paid directly to the installer after the work is completed and inspected by the NIHE. You do not handle the grant money yourself.
Comparing the NI Sustainable Energy Programme to other UK schemes
The NI programme is distinct from the Great Britain-wide ECO4 scheme, which is delivered by energy suppliers and has different income thresholds and eligibility rules. ECO4 is not available in Northern Ireland.
Unlike the Boiler Upgrade Scheme (BUS) in England and Wales, the NI programme is means-tested and not a flat-rate grant for all homeowners. The BUS offers £7,500 for heat pumps without income testing, but is not available in Northern Ireland (GOV.UK, 2026).
The NI programme offers higher maximum grants for heat pumps (£7,500) compared to the BUS’s £7,500, but the NI grant is only available to low-income households. This means the NI scheme targets support at those who need it most, rather than offering universal subsidies.
