Energy Company Obligation (ECO) 4 Flex

 Overview

The Energy Company Obligation (ECO) is a UK Government scheme that funds home energy efficiency improvements to reduce carbon emissions and help fuel-poor households. Funding is provided by energy suppliers.

West Lothian Council participates in ECO4 Flex, identifying eligible households and issuing referrals for funding. However, the council does not provide funding or carry out installations.

Who is Eligible?

You may qualify for ECO4 Flex if you:

• Live in private housing (owner-occupied or privately rented, with landlord permission)
• Are in a fuel-poor household or on a low income
• Have an energy-inefficient home that could benefit from insulation or heating improvements

This scheme does not apply to council or registered social landlord properties.

Statement of Intent (SOI)

How to Apply?

1. Check eligibility in the Statement of Intent
2. Contact an ECO-accredited energy supplier or TrustMark-registered installer for an assessment
3. If eligible, the installer submits your details for approval and carries out improvements at little or no cost

Verify installer details at the TrustMark website (opens new window).

Important Information:

• ECO4 cannot be combined with other government energy schemes such as the Warm Home Discount or Boiler Upgrade Scheme
• Funding is provided by energy suppliers, not the council

What Happens Next?

• An installer surveys your home and submits an application
• If approved, the supplier funds and schedules the installation
• West Lothian Council only assesses eligibility and issues declarations—it does not oversee installations or provide funding
