What is the ECO4 Scheme?
The Energy Company Obligation 4 (ECO4) is a government-backed scheme that requires major energy suppliers to fund energy-saving home upgrades for eligible households across Great Britain. Launched in April 2022, ECO4 replaces the previous ECO3 scheme and continues until March 2026, offering free or heavily subsidised improvements to help reduce your energy bills and carbon footprint.
Unlike traditional grants where you apply directly to the government, ECO4 works differently. Energy suppliers are legally obligated by Ofgem to contribute funding, and you access these grants through approved installer networks. The beauty of ECO4 is that many eligible households can receive upgrades completely free of charge, with no upfront costs.
Who is Eligible for ECO4?
Understanding your eligibility is the first step towards claiming free upgrades. ECO4 has two main eligibility routes: the Low-Income Households route and the Energy Performance Certificate (EPC) route.
For the Low-Income Households route, you must be receiving certain benefits including Universal Credit, Pension Credit, Housing Benefit, or Income-based Jobseeker’s Allowance. Your household income must fall below specific thresholds, which vary slightly depending on your circumstances and location.
The EPC route requires your home to have an Energy Performance Certificate rating of D, E, F, or G. This route doesn’t have strict income requirements, though priority is typically given to lower-income households. You can check your current EPC rating online using Ofgem’s official database.
Additional factors can boost your eligibility. Households with members aged over 70, children under five, or individuals with disabilities often receive priority. Properties in rural areas or off the gas grid may also qualify for enhanced support.
What Upgrades Can You Get for Free?
ECO4 covers a range of energy-saving improvements designed to reduce your heating and cooling costs. Common upgrades include cavity wall insulation, solid wall insulation, loft insulation, and heat pump installation. Some properties may also qualify for boiler replacements with efficient models, draught-proofing, and thermal storage heaters.
The specific upgrades you receive depend on your property type, current energy performance, and identified energy inefficiencies. A professional surveyor will assess your home and recommend the most cost-effective improvements to reduce your energy bills. Most households can expect to save between £200 and £500 annually on energy costs, though savings vary considerably depending on the work undertaken.
How to Check Your EPC Rating
If you’re pursuing the EPC route, you’ll need to find your property’s current rating. Visit the EPC Register on the government website and search using your postcode and address. You’ll instantly see your rating from D to G (if your property qualifies).
If your property doesn’t have a recent EPC, you’ll need to arrange one. An EPC survey typically costs £60 to £120 and takes about an hour. Many surveyors can complete this quickly, and it’s valid for ten years.
Step-by-Step Application Process
The application process is straightforward. First, contact an Ofgem-approved ECO4 installer. You can find approved installers through the official ECO4 website or by searching online for providers in your postcode. Many major home improvement companies and local installers are registered participants.
When you contact an installer, they’ll ask about your property type, current energy performance, and household circumstances. If you haven’t got an EPC, they may arrange this survey. They’ll then conduct a thorough assessment of your home to identify suitable improvements.
Next, the installer will prepare a quotation outlining proposed works. Crucially, if you qualify through the Low-Income route, this should be completely free. Through the EPC route, you may still receive significant subsidies covering most costs, though some households might contribute towards installation.
Once you’ve agreed to proceed, the installer handles all the paperwork and claims the ECO4 funding from energy suppliers on your behalf. You won’t need to interact with your energy supplier directly or deal with complex application forms. The installer manages the entire process.
Finally, the work is scheduled and completed. Approved installers must carry out work to high standards, and you should receive certification confirming the upgrades have been properly installed.
Top Tips for a Successful Claim
Gather your documentation early. Have your benefit statements or proof of income ready if pursuing the Low-Income route. This speeds up verification and gets works scheduled faster.
Compare multiple installers. Whilst the grants are funded centrally, different installers may propose different upgrade combinations. Get several assessments to understand what improvements are recommended for your specific property.
Check the installer’s credentials carefully. Ensure they’re Ofgem-approved and hold relevant qualifications like Gas Safe or NICEIC certification for electrical work. Don’t proceed with installers who aren’t officially registered.
Read terms carefully before signing. Understand what’s included, the timeline for completion, and any guarantees provided. Reputable installers should provide clear written terms.
Common Questions Answered
Will ECO4 affect my energy supplier? Claiming ECO4 grants doesn’t obligate you to stay with your current supplier. Once the work is completed, you remain free to switch suppliers whenever you wish. This is particularly important given current energy market volatility and the importance of finding competitive Ofgem price caps.
Can I claim multiple times? Generally, you can’t claim twice for the same property within a specified period. However, if your property requires multiple different improvements, these can often be bundled into a single claim.
What if my application is rejected? If you’re rejected, request feedback from the installer. You may be eligible through a different route or after circumstances change. Some installers have specialist teams who appeal decisions.
Maximising Your Energy Savings
Once your upgrades are complete, maximise savings by using your heating efficiently. Install a smart thermostat to monitor usage, seal any remaining draughts, and keep radiators unobstructed. These simple steps complement your ECO4 improvements.
