The process for applying for an energy efficiency grant should be straightforward, yet householders lose their funding opportunities because of preventable ECO4 application errors.
The UK government backs the ECO4 scheme, which offers free energy efficiency home improvements to eligible households. The home improvements include insulation and modern heating systems, air source heat pumps, and solar panels.
EcoTarget identifies five main errors that applicants make at the ECO4 grant application process, according to actual application problems we encounter weekly in this guide.
The funding process becomes easier for you when you avoid these mistakes because it saves you time and stops your application from being rejected.
1. Not Checking Eligibility First
The most common ECO4 mistake is applying without confirming eligibility.
The ECO4 scheme mainly supports:
- Households receiving qualifying benefits
- Homes with low EPC ratings (D or below)
- Properties with poor energy efficiency and high heating costs
Submitting an application without meeting the criteria often leads to rejection or delays.
2. Submitting Incomplete or Inaccurate Documents
The main problems that cause ECO4 applications to fail stem from missing or incorrect documentation. The following issues are frequently encountered:
- Outdated benefit letters
- Missing proof of identity
- Incorrect EPC ratings
- Incomplete tenancy details (for renters)
- Energy suppliers require their customers to provide correct and complete documentation. Your application process will experience delays of two weeks if you make one error.
- 3. Choosing the Wrong Installer
Only TrustMark-registered installers are approved to carry out ECO4-funded installations.
The installation of an unapproved installer will lead to two outcomes:
- The funding application will be rejected
- The customer will receive substandard or dangerous installation work
- The customer will receive no protection through warranty or scheme coverage
- This particular error represents the most expensive mistake that applicants make during their ECO4 application process.
- Falling for Non-Government “Grant” Offers
The official ECO4 program does not recognise all online-advertised grants as legitimate funding opportunities.
Some companies promote:
- Finance plans disguised as grants
- Loan-based upgrades
- Paid installations labelled as “free.”
- People who think ECO4 funding only works with private finance deals will lose many thousands of dollars.
- Not Getting Landlord Permission (For Renters)
The tenants must obtain written landlord consent, which must take place before any work can start in their rented space. The application process will experience delays because of this measure, which might also lead to application rejection.
The good news is:
- Most landlords approve upgrades
- ECO4 improvements increase EPC ratings
- They also reduce long-term maintenance issues.
Common Measures Installed Under ECO4
If you qualify, your home may receive one or more of the following upgrades:
- Loft insulation
- Cavity wall insulation
- First-time central heating
- Storage heater upgrades
- Smart heating controls
- Air source heat pumps (ASHP)
- Solar PV panels
