Free Non-Condensing Boiler Replacement Grants UK – Upgrade to Energy Efficiency in 2025

Free Non-Condensing Boiler Replacement Grants UK – Upgrade to Energy Efficiency in 2025

Are you still relying on an outdated, non-condensing boiler to heat your home? If so, you may be missing out on significant energy savings, improved comfort, and—most importantly—a government-backed grant to replace it for free. At Reliant Energy Solutions, we’re helping UK households take advantage of Free Non-Condensing Boiler Replacement Grants through the latest ECO4 Scheme.

What Is a Non-Condensing Boiler?

A non-condensing boiler is typically an older model that vents out hot gases instead of recycling them to preheat cold water. This means higher fuel usage and lower energy efficiency—sometimes below 70%. These systems are costly, environmentally unfriendly, and increasingly obsolete under today’s energy standards.

Why Replace Your Non-Condensing Boiler?

The UK government has prioritised energy efficiency and carbon reduction. As part of this initiative, homeowners and eligible tenants can now replace their non-condensing boilers for free. Here’s why switching matters:

  • Save Up to £300+ Per Year on energy bills 
  • Improve EPC Ratings of your home 
  • Lower your carbon footprint 
  • Access modern condensing boilers with 90%+ efficiency 

Upgrading isn’t just about comfort—it’s about contributing to a cleaner, greener UK.

What Are the Free Non-Condensing Boiler Replacement Grants?

These grants fall under the Energy Company Obligation (ECO4) scheme. The government mandates large energy suppliers to fund heating and insulation upgrades for low-income and vulnerable households.

Through this, Reliant Energy Solutions helps eligible households claim a free boiler replacement without paying a penny.

Who Is Eligible for Boiler Replacement Grant?

You may qualify if:

  • Your current boiler is non-condensing and over 15 years old 
  • You or someone in your household receives qualifying government benefits (e.g., Pension Credit, Universal Credit, Child Tax Credit) 
  • Your property is poorly insulated or has a low EPC rating (E, F, or G) 
  • You are a homeowner or private tenant with landlord permission

Government Schemes Supporting Boiler Replacements in 2025

  1. ECO4 Scheme: Available until 2026, it focuses on whole-home upgrades for low-income households. 
  2. Boiler Upgrade Scheme (BUS): Promotes low-carbon alternatives like heat pumps (not boiler-specific, but helpful if considering futureproofing). 

Reliant Energy Solutions stays up-to-date on these evolving schemes to ensure you get the maximum grant you’re entitled to.

What’s Included in the Free Boiler Grant?

When you qualify, here’s what you can expect:

  • Survey & EPC Assessment 
  • Supply and installation of an A-rated condensing boiler 
  • Removal of the old non-condensing unit 
  • Smart thermostat installation (in many cases) 
  • Pipework adjustments and safety checks 

There are no hidden costs—our service is fully funded by the ECO4 program.
