Local Authority Delivery scheme
This £300 million scheme seeks to cut down on your energy bills by offering energy-efficient solutions, such as External Wall Insulation.

Local Authority Delivery scheme

In 2020, £500 million funding was allocated to local authorities to the Local Authority Delivery (LAD) scheme to improve the energy efficiency of low income and low energy performance households, as part of the UK government’s Green Homes Grant, which closed in 2021.

Phase 2 of the LAD scheme allocated £300 million to Local Net Zero Hubs across the UK, which are currently working with local authorities to reduce fuel poverty and boost the country’s commitment to net zero by 2050. We support this scheme to help cut down on your energy bills by offering energy-efficient solutions, such as EWI.

ECO4 scheme
We back the government Energy Company Obligation (ECO4) scheme. This is designed to tackle fuel poverty, help cut carbon emissions and deliver heating and energy-efficient measures to UK households.

ECO4 scheme

We also back the Energy Company Obligation (ECO4), another UK government energy efficiency scheme which came into force in July 2022 covering a period of four years, which is designed to tackle fuel poverty, help cut carbon emissions and deliver heating and energy efficient measures to households across the country.

It works by placing a Home Heating Cost Reduction Obligation (HHCRO) on medium and large energy suppliers, who must improve measures to help low-income, fuel-poor and vulnerable households heat their homes.

We are proud to be part of TrustMark – the UK government-endorsed quality scheme covering work that consumers choose to have undertaken in or around their home.
