Applying for an energy efficiency grant should be straightforward—but every week, we see people miss out due to simple ECO4 grant application mistakes.
The ECO4 scheme is a government-backed programme offering free home energy upgrades to eligible households across the UK. These upgrades can include insulation, smart heating controls, air source heat pumps, and even solar panels.
In this guide, we’ll cover the top 5 ECO4 grant application mistakes to avoid—based on real-world experience. If you’re planning to apply, this could save you time, stress, and missed opportunities.
1. Not Checking Eligibility First
The most common mistake? Applying for ECO4 without confirming your eligibility.
The scheme focuses on households receiving certain benefits or living in low EPC-rated properties (EPC rating D and below). It also prioritises homes with low energy efficiency and high heating costs.
Checking first avoids unnecessary delays or rejection.
Use our quick tool to check your eligibility.
2. Submitting Incomplete or Inaccurate Documents
From benefit proof to utility bills, incomplete paperwork is one of the leading ECO4 grant application mistakes. Common issues include:
- Outdated benefit letters
- Missing ID
- Incorrect EPC ratings
- Incomplete tenancy details (for renters)
Funding providers require accurate documentation. A single error can cause weeks of delay.
We’ve managed hundreds of successful ECO4 applications. We’ll guide you through every document required.
3. Choosing the Wrong Installer
Only TrustMark-registered installers can deliver ECO4-funded upgrades. One of the most costly ECO4 grant application mistakes is choosing a company that’s not approved.
Why it matters:
- Your funding can be refused
- Installations may not meet safety or efficiency standards
- You won’t be covered by scheme guarantees
We're a certified ECO4 installer. All our work meets the latest standards—and there’s no cost to you if you're eligible.
4. Falling for Non-Government Offers
Be cautious: not every “grant” advertised online is part of the official ECO scheme.
Some companies offer finance deals disguised as “free upgrades.” Confusing ECO4 grants with private funding offers is one of the more subtle—but serious—ECO4 grant application mistakes.
ECO4 is 100% funded by energy suppliers, with no cost to qualifying homeowners or tenants.
5. Not Getting Landlord Permission (For Renters)
If you rent your home, you’ll need your landlord’s written consent before any work can begin. Skipping this step causes delays—and could disqualify your application.
Good news: most landlords support energy upgrades, as they improve EPC ratings and reduce maintenance issues.
We can contact your landlord directly and explain the benefits of the scheme.
