OptamaEco is a government-accredited installer authorised to implement a range of upgrades under the ECO4 scheme, including internal and cavity wall insulation, loft and room in roof insulation, gas boilers, air source heat pumps, high heat retention storage heaters, and solar installations. Our expertise ensures homeowners and tenants can access these energy-saving measures, significantly enhancing home efficiency and comfort through the government-backed Energy Company Obligation scheme (ECO4).

Internal insulation improves energy efficiency by reducing heat loss through walls, leading to lower energy consumption and savings on heating bills.

Cavity wall insulation now incorporates water-resistant materials, significantly reducing heat loss without the risk of damp associated with older types of insulation, leading to energy savings.

Loft insulation acts as a thermal barrier, significantly reducing heat loss through the roof, which lowers the energy needed for heating and results in cost savings on energy bills.

Room-in-roof insulation enhances the energy efficiency of spaces under sloped roofs by reducing heat loss, ensuring these areas stay warmer in winter and cooler in summer, which translates to substantial energy bill savings.

Energy-efficient gas boilers utilise advanced technology to maximise heat production from gas, reducing wasted energy and leading to lower heating costs for homeowners.

Air source heat pumps absorb heat from the outside air to efficiently heat your home and water, significantly reducing the need for conventional heating sources and cutting energy bills.

High heat retention storage heaters are an advancement over old models, efficiently storing energy during cheaper, off-peak hours and releasing it as needed, with improved insulation to reduce heat loss. This results in lower electricity costs and a more consistent temperature, making them a superior choice for energy efficiency and comfort.

Solar panel installations convert sunlight into electricity, allowing homes to generate their own clean energy. This reduces reliance on the grid, lowers electricity bills, and contributes to a sustainable environment by harnessing renewable energy sources.
Free energy-saving upgrades through the ECO4 scheme offer substantial benefits, covering internal and cavity wall insulation, loft and room in roof insulation, solar panels, air source heat pumps, high heat retention storage heaters, and gas boilers. These upgrades significantly enhance energy efficiency in homes, leading to reduced energy bills, increased property value, and improved indoor comfort. Additionally, they contribute to environmental protection by reducing carbon emissions, supporting the UK’s goal for a greener, more sustainable future.

Someone in the home needs to meet eligibility requirements to qualify for ECO4 and free energy-saving upgrades.
You qualify if someone in the home receives one or more of the below benefits:
1) Income based Jobseekers Allowance (JSA)
2) Income related Employment and Support Allowance (ESA)
3) Income Support (IS)
4) Pension Credit Guarantee Credit (PCGC)
5) Working Tax Credit (WTC)
6) Child Tax Credit (CTC)
7) Universal Credit (UC)
8) Housing Benefit
9) Pension Credit Savings Credit (PCSC)
10) Child Benefit (must fall within certain income brackets found here)
You qualify if your household annual income is £31,000 or less.
You qualify if someone in the home has an illness that is made worse by the cold. For example, Asthma, Diabetes and Arthritis. But contact us about any illness that is made worse by the cold to see if we can qualify you.
ECO4 is a government-backed scheme under the UK’s Energy Company Obligation, closely regulated to ensure energy companies meet their obligations to fund energy efficiency improvements in homes, particularly those in lower-income brackets. This initiative represents a strategic government effort to enhance energy efficiency and reduce fuel poverty, with the execution and funding responsibility placed on major energy companies.
The Energy Company Obligation (ECO4) is a government scheme in the UK designed to improve energy efficiency in homes, particularly for those considered in fuel poverty. It’s the fourth iteration of the ECO scheme and runs until March 2026. ECO4 places an obligation on medium and large energy suppliers to promote measures that reduce energy usage, like installing insulation or upgrading heating systems.
The scheme is funded by energy suppliers. Suppliers are required to support low-income, fuel-poor, and vulnerable households in heating their homes more efficiently, which includes providing free upgrades like solar, heating systems and insulation.
There are two parts to eligibility for ECO4.
Firstly, households (homeowners and private tenants) must have someone living in the property receiving certain benefits, living with an illness made worse by the cold, or you can still qualify if your household income is £31,000 or less a year.
Secondly, along with the above, the property also needs to have an EPC of an “E” or below to qualify for ECO4 and free upgrades.
Yes, both private tenants and homeowners can access free upgrades through the ECO4 scheme. This initiative is designed for all types of households, including rentals. However, you’ll need permission from your landlord for any installations.
The scheme is open to social housing and council tenants but you will need to enquire with your property’s manager about this.
Yes, as a homeowner, you are eligible for free upgrades under the ECO4 scheme. This program is designed to help various types of households, including those owned by residents, to become more energy-efficient. If you meet the eligibility criteria, which often include factors like income and current home energy efficiency, you can benefit from energy-saving improvements at no cost. To start the process, you’ll need to check your eligibility and apply through the scheme.
Yes, the ECO4 scheme can assist landlords in upgrading their properties to meet the upcoming Minimum Energy Efficiency Standards (MEES). From April 2025, new tenancies in the UK will require rental properties to have an Energy Performance Certificate (EPC) rating of C or higher, extending to all tenancies by April 2028. The ECO4 scheme provides funding for energy-efficient upgrades, such as insulation or heating system improvements, which can help in raising your property’s EPC rating. While this scheme is a helpful resource, landlords may need to invest further to meet the new EPC requirements.
Yes, as a social housing or council tenant, you can still qualify for free upgrades under the ECO4 scheme. However, it’s important for you to contact your property manager or the housing association that manages your property. They will guide you on how to apply for the scheme and what upgrades are available for your home. It’s their responsibility to initiate and oversee the upgrade process in social housing properties.
