Reviewed

Local guide for Derry / Londonderry homeowners · Kinecx Energy (formerly firmus energy) network
ECO4 does not operate in Northern Ireland. If you live in Derry / Londonderry (BT47–BT48), help with heating and insulation for lower-income private households comes through the Affordable Warmth Scheme NI, delivered by the Northern Ireland Housing Executive (NIHE) for the Department for Communities (DfC). The published rule is a gross household income under £23,000, and you must own and live in your home or rent from a private landlord. Apply through the NI Energy Advice Service on 0800 111 4455; Derry City and Strabane District Council (028 7125 3253) can point you to local fuel-poverty help. The separate Boiler Replacement Scheme is closed. Affordable Warmth has approval through March 2028, and the Warm Healthy Homes Fund is planned from April 2027.
Across Northern Ireland: how Affordable Warmth, NIEAS and devolved funding compare to Great Britain is explained in our Northern Ireland boiler grants hub.

Who qualifies for Affordable Warmth in Derry / Londonderry in 2026?
Affordable Warmth in Derry / Londonderry is for private homes with gross household income under £23,000. Apply through the NI Energy Advice Service (NIHE); your council can help with local fuel-poverty support.
DfC household-income route
Per nidirect's support to stay in your own home page, the Department for Communities sets a gross household income ceiling:
- Gross household income under £23,000
- Owner-occupier or private tenant (with landlord consent)
- Apply via NIEAS 0800 111 4455 (NIHE)
- Social housing (NIHE / housing association) tenants are not covered
Boiler replacement criteria (DfC)
Boiler replacement under Affordable Warmth has additional priority rules on top of the income and tenure tests:
- Boiler replacement under Affordable Warmth is prioritised (per DfC) for households with children under 16, or receiving DLA or PIP, or aged over 65 with a boiler at least 15 years old. These criteria apply on top of the £23,000 income and tenure tests and do not replace them.
Bottom line —If your address is in BT47–BT48, you own or privately rent your home, and your gross household income is under £23,000, call the NI Energy Advice Service on 0800 111 4455 to check Affordable Warmth. Derry City and Strabane District Council (028 7125 3253) can signpost local fuel-poverty help.
Why Derry / Londonderry's stock makes this a high-impact Affordable Warmth city
Derry / Londonderry’s homes fall into a few broad groups. The Cityside (BT48) has older terraces and townhouses in and around the walled city, including Rosemount and the Bogside. These are often solid-walled homes that lose heat quickly, which is why the Department for Communities sets a higher Affordable Warmth limit for solid wall insulation. Creggan, Shantallow, Galliagh, Ballyarnett and Pennyburn are large post-war and later estates built by NIHE. Many homes there are still NIHE-owned, and those tenants are not covered by Affordable Warmth, but homes bought from NIHE and now owner-occupied can be if the household meets the income and tenure tests. The Waterside (BT47) mixes older terraces near the river with newer estates in areas such as Drumahoe, Prehen and New Buildings, while edge-of-city areas such as Culmore, Strathfoyle and Eglinton have more homes off the gas network. Across the city, many lower-income private households still rely on oil or electric storage heating, or on older boilers with poor controls. NIHE decides which measures suit each home.

Bottom line —Derry / Londonderry's stock mix sits squarely inside NIHE's Affordable Warmth catchment — your Technical Officer survey will confirm the right boiler-and-insulation package for your specific property.
Kinecx Energy (formerly firmus energy) covers Derry / Londonderry
Kinecx Energy (formerly firmus energy) is the Gas Distribution Network operator for the Ten Towns natural gas network in Northern Ireland, including Derry / Londonderry, Drumahoe, Eglinton, New Buildings, Prehen and Strathfoyle — that includes every BT47–BT48 postcode.

Oil-fired heating with a boiler more than 15 years old and basic controls; one resident over 65; gross household income under £23,000
Measure installed
Called the NI Energy Advice Service (0800 111 4455), then NIHE assessed the home.

Outcome

Step 2
NIHE assessment
If you appear eligible, NIHE arranges a property check and decides which measures it can fund. Do not start or book any work until NIHE confirms grant aid in writing.

Bottom line —Timelines vary with demand, measures needed and funding — ask NIEAS on 0800 111 4455 when you apply. Derry City and Strabane District Council (028 7125 3253) can help with local fuel-poverty support but does not replace the NIHE application route.
Questions Derry / Londonderry households ask
Does ECO4 apply in Derry / Londonderry?
No. ECO4 is the Energy Company Obligation, a Great Britain scheme covering England, Scotland and Wales. It does not fund work in Northern Ireland. In Derry / Londonderry (BT47–BT48) the route is the Affordable Warmth Scheme, funded by the Department for Communities and delivered by the Northern Ireland Housing Executive. If anyone offers you a “free ECO4 boiler” at a Derry address, check with the NI Energy Advice Service on 0800 111 4455 first.
What is the Affordable Warmth Scheme NI and who qualifies?
It is the Department for Communities’ fuel-poverty scheme for private homes, delivered by NIHE. You may qualify if you own and live in your home, or rent from a private landlord, and your total gross household income is under £23,000. Social housing tenants are not covered. Boiler replacement under the scheme is prioritised for households with children under 16, or who get DLA or PIP, or who are over 65 with a boiler at least 15 years old.
How do I apply for Affordable Warmth in BT47–BT48?
Call the NI Energy Advice Service on 0800 111 4455 or email nienergyadvice@nihe.gov.uk. Since September 2023 applications go to NIHE through this service rather than through council referrals. If you appear eligible, NIHE assesses your home and decides what it can fund. Do not start any work until NIHE confirms approval in writing. Timelines vary, so ask NIEAS about current waiting times.
Is the NIHE Boiler Replacement Scheme still open?
No. The Department for Communities closed the Boiler Replacement Scheme on 21 September 2023, and applications are no longer accepted. Boiler help for lower-income private households now comes through the Affordable Warmth Scheme, if you meet its income, tenure and boiler criteria.
How much is the Affordable Warmth grant?
The Department for Communities says the scheme offers a grant of up to £7,500, or up to £10,000 where solid wall insulation is needed. These are maximums, not a guaranteed amount. NIHE decides which measures to fund after assessing your home.
What is the Warm Healthy Homes Fund, and what happens after 2027?
The Warm Healthy Homes Fund is the Department for Communities’ planned replacement for Affordable Warmth. It is expected to start in April 2027, and the current Affordable Warmth Scheme has approval until March 2028. If you qualify now, you can apply for Affordable Warmth without waiting. This is separate from Great Britain’s Warm Homes Plan.
I heat my home with oil. Can Affordable Warmth help?
Possibly. Affordable Warmth can fund installing or upgrading heating systems as well as insulation, and boiler replacement for eligible households, whatever fuel you use now. NIHE decides what suits your home. If you are thinking about switching to gas, check whether gas is available at your address first. NIEAS (0800 111 4455) can also tell you about oil buying clubs.
Can Free Boiler Upgrade UK approve my Northern Ireland grant?
No. We are an independent information site. We are not NIHE, the Department for Communities, Derry City and Strabane District Council, or an installer, and we do not process Affordable Warmth applications. To apply, contact the NI Energy Advice Service on 0800 111 4455.
