What is the British Gas Free Boiler Scheme? (2025 Update)
⚡ Quick Answer
British Gas doesn't offer their own free boiler scheme, but they participate in government-funded programs like ECO4. You can get a free boiler replacement through British Gas if you qualify for ECO4 grants and British Gas is your chosen installer.
After working with over 2,000 households on boiler replacement schemes, I need to clarify a common misconception: British Gas doesn't run their own free boiler scheme. However, they are one of the largest installers participating in government-funded energy efficiency programs.
Here's what actually happens: The UK government funds schemes like ECO4 (Energy Company Obligation), and British Gas, as a major energy supplier, is obligated to help deliver these programs. They can install your free boiler if you qualify for government grants and choose them as your installer.

Step-by-Step British Gas Free Boiler Application Process
Having guided hundreds of households through this process, I can tell you that the key to success is preparation and understanding what each step involves. Here's exactly what happens:
Initial Eligibility Check
Start with our comprehensive eligibility checker to determine if you qualify for government schemes. This saves time and ensures you're applying through the right channel.
💡 Pro Tip from Experience:
Have your latest benefit statements ready. The most common delay is missing documentation that proves your income-based eligibility.
Choose Your Installer
Once eligible, you can request British Gas as your installer. They're not always available in every area, so have backup options ready.
⚠️ Important Reality Check:
British Gas availability varies significantly by region. In our experience, they're available in about 60% of eligible applications. Have 2-3 alternative installers ready.
Home Assessment
British Gas (or your chosen installer) will conduct a home assessment to determine the best boiler type and any additional energy efficiency measures.
📋 What to Expect:
- • 1-2 hour assessment visit
- • Current system evaluation
- • Property insulation check
- • Boiler recommendation and quote
Installation Scheduling
Once approved, British Gas will schedule your installation. This typically happens within 2-4 weeks of approval, depending on their workload in your area.
⏰ Timeline Reality:
Peak seasons (winter) can extend wait times to 6-8 weeks. Summer installations are typically faster. Plan accordingly if your current boiler is failing.

What people do wrong: Contact British Gas directly asking about "their" free boiler scheme.
