The complete guide to Northern Ireland home energy grants in 2026

Published 13 September 2026 · 5 min read · Reviewed against official sources

Most of what you will read online about UK energy grants does not apply in Northern Ireland. The £7,500 heat pump grant, the Warm Home Discount, ECO4 — all Great Britain schemes, none available to an NI address. Northern Ireland runs its own system, and it is smaller, more targeted at lower-income households, and considerably more generous to those who qualify than most people realise. This guide covers what actually exists, who it is for, and the order in which to approach it.

Start with the one thing that unlocks everything else

Before applying for any grant, get a free benefits check. The Department for Communities runs Make the Call on 0800 232 1271, and in a single year it identified more than £60 million in unclaimed entitlements for Northern Ireland households. That matters here because qualifying for a means-tested benefit — Pension Credit above all — is the key that opens several of the schemes below. It moves you into the priority group for NISEP, it switches on Cold Weather Payments automatically, and it changes the income tests elsewhere. If there is any doubt at all about your entitlement, this call comes first.

Affordable Warmth: the main grant

Run by the Housing Executive for the Department for Communities, Affordable Warmth is the scheme most NI homeowners on a lower income should be looking at. It funds heating and insulation improvements worth up to £7,500 — rising to £10,000 where solid wall insulation is needed — with nothing to repay. The work is carried out by approved contractors and paid for directly; it is not a cash grant.

The test is household income: under £23,000 gross a year for owner-occupiers, rising to £35,000 where someone in the household receives a disability benefit — and PIP, DLA, Attendance Allowance and Carer's Allowance are not counted as income when the test is applied. That disability provision is the one people most often miss, and it brings a substantial number of households into scope who assume they earn too much.

Measures covered include loft and cavity wall insulation, solid wall insulation, draught-proofing, a replacement oil or gas boiler with heating controls, and in some cases windows. It does not currently fund heat pumps or solar panels.

The route in is the NI Energy Advice Service on 0800 111 4455. They check whether you appear to qualify and send an application form for your local Housing Executive office. The scheme was due to end in March 2026 but has been extended while its replacement, the Warm Healthy Homes Fund, is finalised — so apply now rather than waiting for the new fund.

NISEP: the yearly pot

The Northern Ireland Sustainable Energy Programme is funded through a levy on energy bills and administered by the Energy Saving Trust for the Utility Regulator. Each programme year, running April to March, a set of schemes is approved and delivered by around a dozen scheme managers — energy companies, councils and charities — each running their own measures.

At least 80% of the funding is ring-fenced for priority households: anyone receiving a means-tested benefit, or with a household income under £28,000 for a single person or £35,000 for a couple or family. Non-priority schemes exist but have far less money behind them.

What is on offer changes yearly and by scheme manager, but typically covers loft and cavity insulation, heating upgrades, and whole-house packages for priority households. Some scheme managers fund air-source heat pumps for homes off the gas grid — the closest thing NI currently has to a heat pump grant. Grants are first come, first served, and popular schemes have waiting lists before the summer. Applying in April or May matters.

The current list of schemes is published by the Utility Regulator each spring. NISEP has been confirmed to continue until at least March 2029.

Winter Fuel Payment: back for most pensioners

After a single winter in which it was restricted to Pension Credit recipients, the Winter Fuel Payment has returned for everyone of State Pension age from winter 2025/26 — with a catch. It is paid to all, but anyone whose individual income exceeds £35,000 has it recovered in full through the tax system. The threshold applies per person, not per household, so a couple can each receive and keep it provided neither individually earns over £35,000.

The payment is £200 per household, or £300 where someone is 80 or over, and arrives automatically in November or December for anyone receiving the State Pension. You only need to claim if you have never received it and are not on a qualifying benefit.

Cold Weather Payment: automatic, but only if you are on the right benefit

When the average temperature at the weather station covering your postcode is recorded or forecast at 0°C or below for seven consecutive days between November and March, a £25 payment is triggered for each such period. It is paid automatically into the account your benefit goes into — but only if you receive Pension Credit, Income Support, income-based JSA, income-related ESA, or Universal Credit with certain conditions attached.

This is the clearest illustration of why the benefits check comes first. A pensioner not claiming Pension Credit gets nothing from a cold snap; the same pensioner on Pension Credit receives £25 per week of it. Weather stations vary, so neighbouring areas can see different payment counts in the same winter.

Housing Executive and housing association tenants

Social tenants cannot use Affordable Warmth or NISEP, which are aimed at owner-occupiers and private tenants. Instead, the Housing Executive runs its own programme of boiler replacement, heating conversion and insulation for its stock, delivered through planned maintenance. Housing associations run equivalent programmes. If you are a social tenant with a failing boiler or cold home, the route is your landlord, not a grant application.

The schemes that do not exist here

This deserves its own section because the confusion is expensive. The following are Great Britain schemes and are not available to any Northern Ireland address:

The Boiler Upgrade Scheme — the £7,500 heat pump grant. Its regulations cover England and Wales only. Installers advertising "the £7,500 grant" to NI customers are either mistaken or misleading.
The Warm Home Discount — £150 off electricity bills, delivered through GB energy suppliers. Northern Ireland has a separate electricity market and no equivalent.
ECO4 — the supplier-funded insulation programme. GB only.

The Department for the Economy has committed to an NI-specific heat pump grant, but it has not launched. Until it does, NISEP's off-gas-grid heat pump schemes are the only route.

Closed: the Boiler Replacement Scheme

Many websites still list the Housing Executive's Boiler Replacement Scheme — up to £1,000 towards a new boiler for households under £40,000 — as open. It is not. The Housing Executive is honouring approvals already issued but is not taking new applications. If you were counting on it, Affordable Warmth is the route if your income qualifies, and NISEP's heating schemes if it does not.

Putting it in order

Benefits check via Make the Call — it changes everything downstream.
If you own or privately rent and household income is under £23,000 (£35,000 with a disability benefit): Affordable Warmth, via 0800 111 4455.
If you are in the NISEP priority group: check the current year's scheme list and apply early to the relevant scheme manager.
If you are of State Pension age: confirm the Winter Fuel Payment is arriving, and check Pension Credit eligibility to switch on Cold Weather Payments.
If you are a social tenant: contact your landlord about heating and insulation works.

Our eligibility checker walks through exactly these questions and tells you which schemes apply to your circumstances.
