The ECO4 Scheme Boiler grant is significant in the UK’s obligation to enhance home energy efficiency. This government-backed initiative aims to replace outdated, inefficient heating systems with advanced, energy-saving models. It’s a dual-purpose scheme designed to reduce the country’s carbon footprint and significantly offer homeowners a chance to save on their energy bills.

Understanding the ECO4 Scheme Boiler Grant

The ECO4 Boiler Scheme stands at the forefront of the UK’s effort against climate change and promotes energy efficiency. It’s a part of the Energy Company Obligation (ECO), a government program targeting carbon emissions reduction and controlling fuel poverty. 

The ECO phase continues this commitment, focusing on providing ECO4 Scheme Boiler Grant to eligible homeowners and private tenants, thereby enabling the replacement of older, inefficient, non-condensing boilers with modern, highly efficient models.

What is the ECO Boiler Grant?

The ECO Boiler Grant is a crucial UK government initiative to help low-income households upgrade their heating systems without financial burden. ECO4 Scheme Boiler Grant is vital in enhancing home energy efficiency and reducing carbon emissions by offering free boiler replacements. For comprehensive guidance and understanding of how this initiative can benefit you, contact the Government Grants. Our experts are on hand to provide all the necessary information and support.

Features of the ECO Boiler Scheme

The ECO Boiler Scheme is defined by several key features that set it apart:

  • Installing A-rated condensing boilers through the ECO4 boiler scheme ensures top energy efficiency.
  • These boilers have intelligent timers and room thermostats for optimal heating control, maintaining a consistent temperature and offering comfort and energy savings.
  •  It places thermostatic radiator valves on all radiators (except the one in the thermostat room) for efficient heat distribution.

Benefits of Upgrading to an ECO Boiler

The advantages of upgrading to an ECO boiler are numerous:

  • Reduced Energy Bills: The efficiency of a new boiler directly translates into lower energy consumption and, consequently, lower bills.
  • Environmental Impact: By absorbing less energy, you contribute to reducing carbon emissions, aligning with broader ecological goals.
  • Enhanced Home Comfort: Modern boilers offer more effective and consistent heating, improving the overall comfort of your home.

Non – Condensing Boilers VS Condensing Boilers

Non-condensing boilers have an efficiency range of 60% – 70%. We install more efficient variants of condensing boilers with above 90% efficiency. Doing so, we help domestic boiler users move from grades E, F, and G to grades D, C, and B.

                  Features                       Condensing Boilers     Non-Condensing Boilers
Efficiency Above 90% 60%-70%
Carbon Emission As low as 33% As high as 65/75%
Annual Fuel Utilization Efficiency 90-99% Up to 85%
Heat Exchanger Single heat exchanger Two internal heat exchangers
Condensation Reuse heat from burning fossil fuel Heat is released into the atmosphere
Cost Bit Expensive Less expensive
Maintenance Difficult to maintain Easier to maintain
Life Span 15-20 years of life 10-15 years of life

Tenants and homeowners alike stand to benefit from a nationwide free boiler scheme thanks to the government’s most recent Warmth Allowance legislation. Government grants are a one-stop Green Deal installer receiving government funding to replace old, inefficient boilers with more eco-friendly models.

Energy Performance Certificate (EPC) requirements

The EPC rating of the property must show that the building requires improvement. This means properties with an EPC rating of D or higher will not be eligible for ECO4. Homes with an EPC rating of F or lower will receive the appropriate measures to improve the property to at least a D rating.

Meanwhile, homes with an EPC rating of D or E will be upgraded to at least a C rating. The government has stated that they aim to set a minimum target of band E, F and G properties to be upgraded to include the most energy-inefficient properties.

How much does a boiler grant cost?

You may be curious about the cost of getting a new boiler. While some homes can qualify for a completely free boiler replacement, others may receive a partial subsidy from the government, and there are no fees or taxes for applying.

Depending on the model and work needed, a new or replacement boiler typically costs between £2,000 to £7,000. It’s important to understand that the expense of replacing a boiler can vary based on factors like the type of boiler, your home’s size, and how complex the installation is.

The good news is there are some options to help homeowners and private tenants manage the cost of a new boiler. For instance, the government government’s ECO4 scheme provides grants for free boiler replacements to eligible households. If someone doesn’t meet the criteria for this scheme, there could be other schemes for receiving partial payments for boiler upgrades. 

Additionally, some energy suppliers have programs to assist households with the expenses of a boiler replacement.

Installing greener heating systems Via ECO 4 Boiler Scheme

The focus of ECO4 is on the replacement of outdated boilers with more environmentally friendly alternatives. In alignment with the national objective of achieving net zero carbon emissions by 2050, the ECO3 initiative already excluded coal-fuelled heating systems. ECO4 will uphold this policy while expanding the exclusion list to include oil- and LPG-fuelled heating systems.

Under the ECO4 Scheme Boiler Grant, the government encourages households to transition to greener alternatives for their heating needs, particularly emphasizing the adoption of heat pumps and biomass boilers.

Eligibility criteria for the ECO 4 Boiler Scheme

The government has issued £4 billion of funding to the ECO4 scheme, and several changes were made to the eligibility criteria. To qualify for the ECO4 Grant, you must meet the below criteria;

  • Homeowners or private tenants
  • Households with low incomes who receive certain benefits, including:
  • Income-based Jobseeker’sJobseeker’s Allowance (JSA)
