Are you struggling with high energy bills? Worried your old boiler might pack up any day? You’re not alone. Thousands of UK households are getting help right now through the ECO4 scheme including free boiler replacement for pensioners who meet the criteria. But what exactly is it, and could you qualify?
Let’s break it down in simple terms. By the end of this guide, you’ll know exactly how to get your free boiler upgrade.
What Is ECO4 and Why Should You Care?
Think of ECO4 as the government’s way of saying “we’ve got your back” on energy costs. It’s a massive £4 billion programme that helps households get free energy improvements. That includes new boilers, insulation, and even heat pumps.
Here’s the thing: ECO4 isn’t just about individual fixes anymore. It takes a whole-house approach. This means you might get a new boiler AND loft insulation AND better heating controls all at once. Pretty good deal, right?
The scheme runs until March 2026. But here’s the catch – it could end earlier if all the money gets used up. And with 96% of the funding already allocated as of June 2025, time is running out fast.
Who Can Get Help? The Simple Eligibility Test
Wondering if you qualify? The good news is that millions of households are eligible. Let’s look at the two main ways to qualify.
Do You Get Any of These Benefits?
If you receive any of these, you’re likely eligible:
- Universal Credit
- Pension Credit
- Child Tax Credit or Working Tax Credit
- Jobseeker’s Allowance (income-based)
- Employment Support Allowance (income-related)
- Income Support
- Housing Benefit
- Child Benefit (with income limits)
For Child Benefit recipients, your household income matters. A single person can earn up to £14,700. A couple with a school-age child can earn up to £29,300.
What About Your Home?
Your property also needs to meet certain rules:
- It must have an Energy Performance Certificate (EPC) rating of D, E, F, or G
- Your home must be a house, bungalow, or flat
- The improvements must bring your EPC rating up by at least one band (you can check with an EPC points calculator to estimate your upgrade potential)
Got a rating of C or above? Unfortunately, you won’t qualify for ECO4.
The ECO4 Flex Option: A Second Chance
Don’t get the right benefits? There’s still hope. Local councils can help households through ECO4 Flex if:
- Your household income is below £31,000 per year
- Someone in your home is elderly, disabled, or has health problems
- You have young children or newborns
- Anyone has breathing or heart conditions
Your local council decides who gets help through this route. It’s worth asking them directly.
What Can You Actually Get? The Full List of Freebies
ECO4 covers way more than just boilers. Let’s look at what’s on offer and how it could transform your home.
Heating Upgrades That Make a Real Difference
The heating improvements are the real stars of the show:
- New boiler installation – Perfect if your old one is on its last legs
- Air source heat pumps – The future of home heating
- First-time central heating – For homes that never had it
- Smart heating controls – Help you use less energy automatically
- District heating connections – In some areas
Insulation: The Unsung Hero of Energy Saving
Why do we mention insulation? Because it works hand-in-hand with your new boiler:
- Loft insulation (270mm thick – that’s proper insulation!)
- Cavity wall insulation
- Solid wall insulation
- Underfloor insulation
- Room-in-roof insulation
The Extras That Add Up
You might also get:
- Solar panels (in some cases)
- Energy-efficient windows
- Draught proofing
- High-performance doors
Here’s an interesting fact: nearly half of all ECO4 installations are heating controls. They’re popular because they’re quick to install and save money immediately.
How to Apply: Your Step-by-Step Action Plan
Ready to get started? The application process is simpler than you might think. Here’s exactly what to do.
Step 1: Check If You Qualify
Start with an online eligibility checker. Many approved installers have these on their websites. You can also contact Citizens Advice for free help.
Step 2: Find a Trusted Installer
This bit is crucial. Only work with ECO4-approved providers. They’re registered with Ofgem, the energy regulator. Always check their credentials and read customer reviews.
Step 3: Get Your Home Assessed
A certified assessor will visit your home. They’ll:
- Check your current energy performance
- Identify what improvements you need
- Make sure everything meets the required standards
- Calculate how much you’ll save on bills
Step 4: Review Your Improvement Plan
You’ll get a detailed report showing:
- Exactly what work will be done
- How much you’ll save each year
- When will the work happen
- What you need to do to prepare
Step 5: Sit Back and Let the Experts Work
The installation happens at no cost to you. Professional installers do all the work. They’ll test everything to ensure it works properly and give you warranties.
What’s the Real Impact? The Numbers That Matter

Important Things to Know Before You Apply
Time Is Running Out
ECO4 ends in March 2026, but it could finish earlier. With 96% of funding already allocated, don’t delay your application.
Special Rules for Renters
If you’re a private tenant, you’ll need your landlord’s written permission before any work starts. The good news? Landlords can’t charge you for these improvements.
Supply Chain Challenges
The retrofit industry has capacity limits. There are fewer skilled installers than in previous years. This means longer waiting times, so apply early.
Final Thoughts
ECO4 has already helped over 226,700 households save millions on energy bills. With limited time and funding left, eligible households need to act fast.
Start by checking your eligibility online today. If you qualify, contact an approved installer immediately. The sooner you apply, the sooner you could be enjoying a warm, efficient home with much lower energy bills.
Remember: this is completely free money from the government. Your only job is to check if you qualify and apply. Everything else is taken care of for you. The question isn’t whether you can afford to get ECO4 improvements. It’s whether you can afford not to.
