LA Flex Rejection Reasons Explained

If you have any concerns about your application, knowing and solving the possible rejection reasons can help you move forward with confidence.
The most common LA Flex rejection reasons and solutions:
- Incorrect or incomplete application forms: When forms are filled out accurately and signed properly, the application process can progress smoothly.
- Sufficient proof of income: Submitting accurate payslips or bank statements in line with council requirements supports a successful review.
- Suitable Energy Efficiency Rating: Homes with EPC ratings of D, E, F, or G are well-positioned for LA Flex support, as the scheme is designed to prioritise properties that can benefit most from energy efficiency grants.
- Council Income Guidelines: Each local authority sets an income threshold (typically around £31,000), and applications that fall within this range are well aligned with LA Flex funding criteria.
