Free Solar Panels in Northern Ireland: What the Offer Really Is

The short version, checked on 6 September 2026

I run this site, and “free solar panels” is one of the most common things people arrive here looking for. There is no such thing in Northern Ireland. There never has been. Everything below was checked against the primary source on 6 September 2026.

What the advert says	What it is
”Government funded free panels”	No NI grant funds domestic solar PV. None ever has.
”Free panels under the Warm Homes Plan”	The Warm Homes Plan is a Great Britain programme. Energy efficiency policy is devolved.
”ECO4 will cover it”	ECO4 is an obligation on Great Britain suppliers. It does not run here.
”Rent your roof, we fit them free”	Rent-a-roof ran on the Feed-in Tariff. The FiT was Great Britain only and closed on 1 April 2019.
”Free with 0% finance”	A loan. You pay the full price, in instalments.
”Check if you qualify”	Usually a form. There is no eligibility rule to check against.
The one real universal support	0% VAT, until 31 March 2027.
The one real grant, not for solar	Affordable Warmth, up to £7,500, insulation and heating only.

Why Northern Ireland has no free-panel route at all

This is the part most UK-wide articles get wrong, because they write for England and add a Northern Ireland sentence at the end.

Four separate mechanisms pay for other people’s panels elsewhere. Not one of them reaches a house here.

The Feed-in Tariff. Ofgem’s scheme paid a fixed rate for every unit a small system generated, for 20 years. It applied in Great Britain, and its costs were levelised across licensed suppliers in Great Britain. It closed to new applicants on 1 April 2019.

Rent-a-roof. This is the mechanism that made “free solar panels” a real offer in the first place. A company fitted panels at no upfront cost, leased your roof for 20 to 25 years, and kept the Feed-in Tariff payments. Which? describes the model plainly: the companies “were keen to cash in on the feed-in tariff”. Take the FiT away and the sums stop working, which is why the model collapsed in GB after 2019. In NI it never started.

The Smart Export Guarantee. The FiT’s replacement is also Great Britain only. Ofgem’s eligibility wording is that installations “must be located in Great Britain”. NI suppliers pay for exported electricity voluntarily instead, typically 5 to 8p per kWh, which is a commercial offer rather than an entitlement. Our guide to solar export payments in NI covers who pays what.

The Boiler Upgrade Scheme and ECO4. The BUS is “open to people in England and Wales”. ECO4 is described by Ofgem as “a government energy efficiency scheme in Great Britain” and runs to 31 December 2026. Neither one touches an NI address, and neither funds solar PV anyway.

That leaves the domestic support that does exist here, which is 0% VAT and nothing else. The full picture is on our solar panel grants in NI page.

The three things a “free solar” advert turns out to be

1. Finance dressed as free

The most common version. Nothing to pay today, a monthly figure smaller than your current electricity bill, and the word “free” doing work it has not earned. You own the panels and you owe the money. That is a reasonable way to buy solar, and I would rather people did it with their eyes open than not at all.

The thing to check is whether the 0% is real. A genuine 0% APR deal costs you exactly the cash price, spread out. On a £7,000 system at 0% over five years that is £116.67 a month. A fake one has the cost of credit baked into a higher installation price: if the 0% installer wants £8,500 for a system others price at £7,000, that £1,500 is interest with a different name on it. Our solar panel finance options guide compares the real rates from NI banks and credit unions, usually 3% to 6.5% APR.

2. A grant that does not exist

The second version cites a scheme. Sometimes it is ECO4, sometimes the Warm Homes Plan, occasionally something invented outright. The tell is that no NI scheme is named, because there is no NI scheme to name. The Housing Executive is explicit that Affordable Warmth funds insulation, ventilation, draught-proofing, heating, windows and solid wall measures. Solar PV has never been on that list.

If a salesperson tells you they can arrange grant-funded panels for a Northern Ireland home, they are either misinformed or lying. There is no third reading.

3. A form that sells your number

The third version is not selling panels at all. “Check if you qualify for free solar panels” is a lead form. Your name, postcode and mobile number go to installers, or to a broker who resells the record to several of them, and then the phone starts.

I should be straight here, because this site passes details to installers too. That is how a comparison site works. The difference I would ask you to look for is whether the site tells you what it does with your details before you type them in, names who will contact you, and stops when you say stop. Under regulation 21 of the Privacy and Electronic Communications Regulations 2003, a live marketing call to a number registered with the Telephone Preference Service is unlawful unless you told that specific company you were happy to hear from them. A “free panels” quiz that ends in six cold calls has usually not cleared that bar.

The broader tactics are set out in our guide to solar panel scams in NI.

What 0% VAT is actually worth

Since 1 May 2023, domestic solar installations in Northern Ireland are zero-rated for VAT under HMRC Notice 708/6. NI is worth stating separately: Great Britain got the zero rate in April 2022, while NI stayed on the 5% reduced rate until 30 April 2023. The zero rate ends on 31 March 2027, after which 5% applies again.

In money: a £7,000 installation with 20% VAT added would be £8,400, so the zero rate is worth £1,400 on that job. It covers panels, inverter, battery and labour, every household qualifies with no means test, and no salesperson arranges it for you. Any domestic quote from an MCS-certified installer should already be zero-rated. See our 0% VAT on solar panels guide for the detail.

What to ask when someone rings or knocks

Six questions. They take two minutes and they end most of these conversations.

1. What is your MCS registration number? Write it down and check it on the MCS register yourself.
2. Which grant, by name, and which department or body administers it in Northern Ireland?
3. Do I own the panels at the end, or does anyone else have an interest in my roof?
4. Is this finance? If so, who is the lender, what is the APR, what is the total amount payable, and are they on the FCA’s Financial Services Register?
5. Who else will receive my details from this call, and when will contact stop if I ask?
6. Send me the quote in writing, itemised, and I will come back to you after I have two others.

If a contract is signed at your door you have 14 days to cancel it under regulation 30 of the Consumer Contracts Regulations 2013. Nobody who intends to honour that will mind you saying so out loud.

Who genuinely can get help

If your total gross household income is under £23,000 and you own and live in the property or rent privately, the Affordable Warmth Scheme is real money: up to £7,500, or £10,000 where solid wall insulation is needed, with no contribution from you. It has business case approval to March 2028. Ring NI Energy Advice on 0800 111 4455.

It will not put panels on your roof. For a cold house with an old boiler it is worth considerably more than solar would be, and I would rather send you there than sell you something.

What a real quote looks like

There is no free system, so the money you save comes from buying well. On this site’s solar tracker, a 4kW system in Belfast produced 2,227 kWh across the 225 measured days from 24 January to 5 September 2026, worth £746 at the 33.5p per kWh the tracker assumes. Newry did best at 2,265 kWh. Power NI’s published standard domestic unit rate from 1 July 2026 is 34.15p including VAT, so the tracker’s assumption is slightly conservative.

Against that, a 4kW installation costs £6,000 to £8,000, set out by size in our solar panel costs guide. Of the 368 quote requests this site has taken since March, 246 came from households with a monthly bill between £100 and £250, and 99 said they were only after a rough price. That is a sensible place to start. The spread between the cheapest and dearest quote for the same specification is routinely over £1,000, a bigger lever than any offer with the word free in it.
