# ECO4 Flex Route 4: Bespoke Targeting

ECO4 Flex Route 4 gives the local authorities the opportunity to propose new methods for identifying low-income and vulnerable consumers.

**This route is only available with ECO4 Flex**.

An application should be submitted to the Department of Energy Security and Net Zero (**DESNZ**) and is required to show that:

1. The proposed methodology is more effective at identifying fuel-poor consumers than the criterion offered in both Routes 1 and 2.
2. More than 50% of the premises that meet the criteria are not receiving any of the following benefits:

- Income Based Jobseekers Allowance (JSA)
- Income-related Employment and Support Allowance (ESA)
- Income Support (IS)
- Pension Credit Guarantee Credit (PCGC)
- Working Tax Credit (WTC)
- Child Tax Credit (CTC)
- Universal Credit (UC)
- Housing Benefit
- Pension Credit Savings Credit (PCSC)
- Child Benefit

And at least either:

1. 75% of the premises that meet the criteria are owner-occupied premises occupied by at least one living person in fuel poverty; or
2. 90% of the premises that meet the criteria are privately rented and are occupied by at least one person living in fuel poverty.

### Submitting Applications

To submit an application, Local Authorities should share an application form with **ecoteam@energysecurity.gov.uk**for assessment and approval.

Once the Department of Energy Security and Net Zero approve an application, they will provide a reference number. This should be used to notify Ofgem of all relevant projects under ECO4 Flex Route 4.
