Warm Homes Plan Northern Ireland: Free Solar Panels for Eligible Households

What Is the Warm Homes Plan?

The Warm Homes Plan is the Northern Ireland Executive’s flagship energy efficiency programme, designed to tackle fuel poverty across the region. You may also see it referred to as the warm homes scheme or warmer homes scheme, though its official name is the Warm Homes Plan. It provides free energy efficiency improvements to eligible households, including solar panels, insulation, heating system upgrades, and draught-proofing.

Northern Ireland has some of the highest rates of fuel poverty in the United Kingdom. According to government figures, around 24% of households here struggle to heat their homes adequately. The Warm Homes Plan exists to address this by making homes warmer, cheaper to run, and less dependent on fossil fuels.

For eligible homeowners, the scheme covers up to 100% of installation costs, making it one of the most generous energy efficiency programmes available anywhere in the UK.

History: From Warm Home Scheme to Warm Homes Plan

If you have searched for “warm home scheme NI” or “warm homes scheme Northern Ireland”, you have found the right place. The Warm Homes Plan replaced two earlier programmes that had been running for over a decade:

• The Warm Home Scheme, which was managed by the Northern Ireland Housing Executive (NIHE) and primarily targeted homeowners on qualifying benefits. Many people still search for the warm home scheme by its original name.
• The Affordable Warmth Scheme, which was delivered through local councils and focused on low-income households in the worst-performing properties.

Both schemes achieved significant results. Over their lifetime, they improved tens of thousands of homes and helped reduce energy costs for families across every council area. However, the two-scheme approach created confusion. Many people were unsure which programme to apply for, and the eligibility criteria overlapped in ways that made the system harder to navigate than it needed to be.

The Warm Homes Plan consolidated the former warm home scheme and Affordable Warmth Scheme into a single, streamlined programme. The goal was simple: one application route, clearer eligibility rules, and a broader range of measures (including solar panels, which were not widely available under the earlier schemes). Whether you knew it as the warmer homes scheme, warm homes scheme, or warm home scheme, it is now all under one roof.

Full Eligibility Criteria

Eligibility for the Warm Homes Plan is based on three factors: your housing status, your financial circumstances, and the current condition of your property.

Housing status

You must be one of the following:

• A homeowner occupying the property as your main residence
• A private tenant with written consent from your landlord

Housing Association tenants and Northern Ireland Housing Executive tenants are not eligible, as those properties are covered by separate social housing improvement programmes.

Qualifying benefits

You must be in receipt of at least one of the following means-tested benefits:

• Universal Credit (with a household income below the relevant threshold)
• Pension Credit (Guarantee Credit or Savings Credit)
• Income Support
• Income-based Jobseeker’s Allowance (JSA)
• Income-related Employment and Support Allowance (ESA)
• Child Tax Credit (with an annual household income below £16,190)
• Working Tax Credit (with an annual household income below £16,190)
• Disability Living Allowance (when combined with a low household income)
• Personal Independence Payment (PIP) (when combined with a low household income)
• Attendance Allowance (when combined with a low household income)
• Carer’s Allowance (when combined with a low household income)

If you are not on any of the benefits listed above but your total household income is below approximately £23,000 per year, you may still qualify through the low-income pathway. This replaced the former Affordable Warmth route and is assessed through your local council.

Property requirements

Your property must meet all of the following conditions:

• Located in Northern Ireland
• Your permanent, primary residence (not a holiday home or second property)
• Has an Energy Performance Certificate (EPC) rating below Band C (i.e. rated D, E, F, or G)
• Has not already received the maximum measures available under the Warm Homes Plan or its predecessor schemes

Properties of any age and construction type can qualify, including detached houses, semi-detached homes, terraced houses, bungalows, and flats. However, listed buildings or properties with unusual construction may have restrictions on which measures can be installed.

What Measures Are Available?

The Warm Homes Plan funds a range of energy efficiency improvements. The specific measures offered to you will depend on the results of a professional home energy assessment. Here is a detailed look at each.

Solar panels (photovoltaic systems)

Solar PV panels convert sunlight into electricity that you can use in your home. A typical domestic installation under the Warm Homes Plan is a 3kW to 4kW system, consisting of 8 to 12 panels on a suitable roof. To understand the full costs of solar panels in Northern Ireland, including what you would pay outside the scheme, see our detailed guide.

Solar panels are generally recommended for properties that already have adequate insulation. If your home needs insulation work first, the scheme will typically arrange that before installing panels. This “fabric first” approach ensures your home retains the energy it generates.

Key details:

• Systems typically generate 2,500 to 3,400 kWh of electricity per year
• Panels come with a manufacturer warranty of 25 years
• No planning permission is usually required (most domestic installations fall under permitted development)
• The installation takes one to two days for a standard system

Cavity wall insulation

If your home has unfilled cavity walls, this is one of the most cost-effective improvements available. Insulation material is injected into the gap between your inner and outer walls, reducing heat loss significantly.

• Typical installation time: half a day to one day
• Minimal disruption; small holes are drilled in the external mortar joints and filled after injection
• Can reduce heat loss through walls by up to 35%

Loft insulation

Heat rises, and an uninsulated or under-insulated loft is one of the biggest sources of energy waste in any home. The scheme funds loft insulation to the recommended depth of 270mm.

• Suitable for most homes with accessible loft spaces
• Installation takes a few hours for a standard loft
• Can reduce heating bills by up to £250 per year

Draught-proofing

Draughts around doors, windows, letterboxes, and other openings waste significant amounts of heat. Draught-proofing involves fitting seals, strips, and covers to reduce uncontrolled air leakage.

• Quick to install, usually completed within a few hours
• One of the cheapest measures but delivers noticeable comfort improvements
• Particularly effective in older properties with original timber windows and doors

Heating system replacements

If your current boiler or heating system is old, inefficient, or broken, the Warm Homes Plan can fund a replacement. This typically includes:

• A new A-rated condensing gas or oil boiler
• Upgraded heating controls (programmable thermostat and thermostatic radiator valves)
• In some cases, a first-time central heating system for homes that previously had no central heating

A modern condensing boiler operates at around 90% efficiency, compared to 60% or less for older models. This alone can save hundreds of pounds per year.

Hot water cylinder jackets

A simple but effective measure. An insulating jacket fitted around your hot water cylinder reduces heat loss and keeps water hotter for longer, cutting your energy use.

Step-by-Step Application Process

Applying for the Warm Homes Plan is straightforward. Here is exactly what to expect at each stage.

Step 1: Make initial contact

Contact the Northern Ireland Housing Executive on 03448 920 900. Alternatively, you can apply through your local council’s environmental health or energy efficiency team. Many councils accept referrals online or by phone.

You can also ask a trusted third party (such as a community advice worker, Citizens Advice, or an energy advice service) to make a referral on your behalf.

Step 2: Eligibility screening

During your initial contact, a member of staff will ask some basic questions to confirm you are likely to qualify. They will ask about:

• Your address and property type
• Which benefits you receive (or your household income)
• Whether you own or rent the property
• Any previous energy efficiency improvements you have received

If you appear to meet the criteria, they will book a home assessment.

Step 3: Home energy assessment

A qualified energy assessor will visit your property. This visit typically lasts 45 minutes to one hour. The assessor will:

• Inspect your walls, loft, windows, and doors
• Check your current heating system and controls
• Examine your hot water system
• Assess roof orientation and suitability for solar panels
• Carry out or review an Energy Performance Certificate (EPC)

You do not need to prepare anything special for this visit, though it helps to have your loft hatch accessible and any benefit letters or proof of income to hand.

Step 4: Receive your recommendations

After the assessment, you will receive a report detailing which measures your home qualifies for. This may include one measure or several. For example, a property might be recommended for loft insulation, cavity wall insulation, and solar panels.

You are under no obligation to accept. However, be aware that solar panels are typically only offered if your home already has adequate insulation (or if you agree to have insulation installed at the same time).

Step 5: Installation

Once you agree to proceed, the scheme will appoint approved contractors to carry out the work. You will be given a date for the installation.

Key points about the installation process:

• All contractors are vetted and approved by the scheme. You do not need to find your own installer.
• Insulation work is usually done first, followed by heating upgrades, and finally solar panels.
• Most insulation jobs take one day or less. Solar panel installations take one to two days.
• Contractors will need access to your loft, walls, and roof. For solar panels, they will also need to work in the area where your consumer unit (fuse board) is located.
• All work is inspected after completion to ensure it meets quality standards.
• You will not pay anything. The full cost is covered by the scheme.

Step 6: Post-installation

After the work is completed, you will receive documentation including:

• MCS certification for solar panel installations
• Warranty information for all materials and workmanship
• Guidance on how to use any new systems (such as solar monitoring or heating controls)
• An updated EPC for your property

The entire process, from first contact to completed installation, typically takes 4 to 12 weeks, depending on demand and the complexity of the work required.

How Much Can You Save?

The financial benefits of the Warm Homes Plan are substantial. Here is a breakdown of typical savings for each measure.

Solar panel savings

Benefit	Estimated Value
Installation cost saved	£5,000 to £8,000
Annual electricity bill reduction	£300 to £600
Annual export payments (SEG)	£50 to £100
25-year total benefit	£13,000 to £25,000

Solar panels generate the most electricity between March and September, but they do produce power year-round, even on cloudy days. Northern Ireland receives enough sunlight to make solar panels a worthwhile investment. For a full analysis, see our guide to solar panel costs in Northern Ireland.

Insulation savings

Measure	Typical Annual Saving
Cavity wall insulation	£150 to £300
Loft insulation (0mm to 270mm)	£200 to £250
Loft top-up (100mm to 270mm)	£50 to £100
Draught-proofing	£30 to £60

Heating system savings

Measure	Typical Annual Saving
Old boiler replaced with A-rated condensing boiler	£200 to £400
Heating controls upgrade	£75 to £150
Hot water cylinder jacket	£35 to £45

Combined savings example

A household that receives cavity wall insulation, loft insulation, a new boiler, and solar panels through the scheme could save £750 to £1,300 per year on energy bills. Over 10 years, that amounts to £7,500 to £13,000 in savings, all from improvements that cost the homeowner nothing.

Homeowners vs Tenants: What You Need to Know

If you are a homeowner

The process is straightforward. You apply directly, and if eligible, the work is carried out on your property at no cost. The improvements become a permanent part of your home and can increase its value and EPC rating, both of which are beneficial if you ever decide to sell.

If you are a private tenant

You can benefit from the scheme, but there are additional steps:

• Your landlord must provide written consent for the work to go ahead. The scheme administrators can provide a standard consent form.
• The landlord does not need to contribute financially. The scheme covers the full cost.
• The improvements stay with the property, not the tenant. If you move, the next occupant benefits from them.
• Your landlord cannot increase your rent solely because energy efficiency improvements have been made through a government scheme.

If your landlord is reluctant to give consent, it may help to explain that the improvements are fully funded, increase property value, and improve the EPC rating (which landlords are increasingly required to maintain at certain levels).

If you are a Housing Association or NIHE tenant

You are not eligible for the Warm Homes Plan, as your housing provider has separate obligations and programmes to improve energy efficiency in their stock. Contact your Housing Association or the NIHE directly to ask about planned improvements to your home.

What If You Do Not Qualify?

If you do not meet the eligibility criteria for the Warm Homes Plan, you still have several options for reducing your energy costs with solar panels.

Compare quotes from MCS-certified installers

The single most effective way to get a good price on solar panels is to compare quotes from multiple installers. Homeowners who compare at least three quotes typically save over £800 compared to accepting the first quote they receive. Our free comparison service connects you with MCS-certified installers across Northern Ireland.

Other grant schemes

Several other programmes can help with the cost of solar panels and energy efficiency improvements:

• Solar panel grants in Northern Ireland: A complete overview of every grant and incentive currently available to NI homeowners.
• Commercial solar grants: If you run a business, farm, or community organisation, separate funding streams are available.
• NISEP (Northern Ireland Sustainable Energy Programme): Funded by energy suppliers rather than government, NISEP offers energy efficiency measures through a different set of eligibility criteria. See below for more on how NISEP and the Warm Homes Plan relate to each other.

Finance options

If you do not qualify for any grant but still want solar panels, solar panel finance options allow you to spread the cost over monthly payments. Many installers offer 0% finance deals, and even with interest-bearing finance, the monthly repayments are often lower than the energy savings you gain.

VAT exemption

All domestic solar panel installations in Northern Ireland are exempt from VAT. This saves you 20% compared to the standard rate and applies whether or not you receive a grant.

The Relationship Between the Warm Homes Plan and NISEP

People often confuse these two programmes, so it is worth clarifying how they differ.

	Warm Homes Plan	NISEP
Funded by	NI Executive (government)	Energy suppliers (SSE Airtricity, Power NI, etc.)
Administered by	NIHE and local councils	Energy suppliers and approved scheme managers
Target group	Fuel-poor households on qualifying benefits or low income	Broader eligibility, including some households not on benefits
Measures available	Solar panels, insulation, heating, draught-proofing	Insulation, heating, some renewable measures
Cost to householder	Free (100% funded)	Free or heavily subsidised

In some cases, households can benefit from both programmes. For example, you might receive insulation through NISEP and later qualify for solar panels through the Warm Homes Plan. The two schemes are designed to complement rather than duplicate each other.

Common Misconceptions

“Solar panels don’t work in Northern Ireland because it rains too much.” This is incorrect. Solar panels work with daylight, not direct sunshine. Northern Ireland receives enough solar irradiance to make PV systems effective. A typical 4kW system here generates around 3,400 kWh per year, which is enough to cover a significant portion of an average household’s electricity use.

“The scheme has a long waiting list and takes years.” Processing times vary by area and demand, but most applications are completed within 4 to 12 weeks. Some areas may experience longer waits during peak periods, but the scheme is actively managed to keep timescales reasonable.

“If I get free solar panels, I will have to pay the government back eventually.” No. The Warm Homes Plan is a grant, not a loan. There is no repayment obligation, no charge on your property, and no ongoing fees.

“My home is too old for solar panels.” Age alone does not disqualify a property. The key factors are roof condition, orientation, and structural suitability. The home assessment will determine whether your roof can support panels. Many older properties in Northern Ireland have had solar panels successfully installed.

“I already had loft insulation done years ago, so I will not qualify.” Having some previous work done does not automatically disqualify you. If your existing insulation is below the current recommended depth, or if other measures (such as solar panels or a boiler upgrade) are still needed, you may still qualify for those.

Take the Next Step

If you think you might be eligible for the Warm Homes Plan, contact the Northern Ireland Housing Executive on 03448 920 900 to start your application. There is no cost to apply, and the home assessment is free.
