Is a grant for free home insulation or solar panels a scam?
Government insulation and solar grant schemes are real, but cold calls or door-knockers offering them are frequently used to set up fraud or high-pressure selling.

Explanation
Countries including the UK and US do operate legitimate energy-efficiency grant programmes (such as the UK's ECO scheme or the US Weatherization Assistance Program). However, this creates cover for fraudsters who cold-call or knock on doors claiming to access 'government grants' on your behalf. In some cases they are simply salespeople for expensive products that are not fully grant-funded. In others they charge upfront fees to apply for a grant that is actually free, or they conduct poor-quality installation work and disappear. Genuine grant applications are made through official government or energy-company portals and never require upfront cash payments. Always verify through the official government website for your country or region.
The grant framing is effective because it borrows the government's credibility while removing the government from the transaction. Everything then hinges on trusting the intermediary at your door or on the phone — and the harms range accordingly, from paying for 'free' applications, to expensive finance agreements dressed up as grant-funded installations, to substandard work that can damage the property it was meant to improve. Poorly installed insulation and rushed solar fittings create problems that cost far more to fix than the original work, and the installer is usually unreachable by then.
The safe sequence runs in one direction: start from the official scheme, confirm you qualify, and choose an installer from the scheme's own accredited list — rather than starting from whoever contacted you and trusting their account of the scheme. Get everything in writing before any work begins, including what is grant-funded and what you would owe, and be wary of anyone whose deadline pressure is doing the persuading.
Common red flags
- Unsolicited call or door visit offering a government grant for your home
- Offer requires an upfront payment or deposit
- Pressure to decide immediately before the grant 'runs out'
- Installer cannot provide verifiable trade credentials or insurance
- Company name cannot be found on official trade or government installer registers
What to do now
- Check the official government website for legitimate grant schemes in your area
- Ask for written quotes and verify the installer's accreditation independently
- Never pay cash upfront for work promised under a government scheme
- Report aggressive or fraudulent approaches to your consumer protection body
Frequently asked questions
How do I find a legitimate home-insulation grant in the UK?
In the UK, check the official GOV.UK website for the Energy Company Obligation (ECO) scheme. Installers must be MCS-certified and are listed on the official MCS register.
The caller says the grant deadline is this week — should I hurry?
No. Deadline pressure is a sales device. Genuine scheme dates are published on official government pages where you can check them calmly, and a legitimate installer's quote survives a week of thought. Anything that expires the moment you want to verify it was never real.
