The government’s ECO boiler grants
The UK government’s Energy Company Obligation Scheme (ECO) was introduced to help vulnerable homeowners across England, Scotland and Wales with the reduction of their energy bills.
The New Boiler Grant team have been focused on ECO since it started in 2013. This website offers the latest ECO4 grant funding that is set to run from 1 April 2022 until 31 March 2026.
ECO4 brings a range of changes to the Government Boiler Grant scheme that we’ve been used to over the past 4 years during ECO3. The main change is a focus on improving energy efficiency of a property rather than reduction of fuel bills. It introduces the Whole House Approach. This means that ECO qualified installers will have to complete as many measures in a property as possible to increase its energy rating to as highest possible standard.
The free boiler grants are funded by UK energy companies and don't need to be repaid. See if you qualify now.

From HHCRO to HECRO scheme
While ECO3 carried the sub obligation HHCRO (Home Heating Cost Reduction Obligation), this has changed to HECRO (Home Energy Cost Reduction Obligation) with ECO4. The approach is now more than just reducing the customers heating bills but decreasing all their energy bills together.
This change from HHCRO to HECRO means there is a far larger emphasis on renewable heat and energy sources in ECO4. Despite this, there is no funding for mains gas properties to be converted to be heated by Air Source Heat Pumps yet. At the same time the government want qualifying gas properties to be “heat pump ready” for forthcoming improvements.

Qualifying consumers are allowed to combine various funding routes as long as the measures covered by them are different. For example, a customer can claim the £5,000 voucher from the Boiler Upgrade Scheme to change their mains gas boiler to ASHP, and have their home insulation done with ECO4.
All homes with EPC rating of D and receiving Gas Boiler Grant or Air Source Heat Pump must first have at least one primary insulation measure installed (flat roof, loft, room-in-roof, cavity wall, solid wall or floor insulation). This rule is not related to the homes receiving First Time Central Heating (FTCH) Grant.
However, all homes with EPC rating of E, F, G and receiving Gas Boiler Grant or Air Source Heat Pump, plus homes with EPC rating of D receiving FTCH Grant must first have all cavity walls and loft or roof insulation done to the latest standards. This effectively means that if there is Cavity Wall Insulation or Loft/Roof Insulation to install then it MUST be done - all completely FREE to you.
Eligible Benefits
With ECO4, there are now 8 core benefits that you can use to claim your FREE Boiler Grant:
How much can I save?
A new A-rated and installed boiler can cost c.£1.5 - 4.5k. But with the ECO grant you can receive one for free, or with a contribution. Click below to find out more.

After you Qualify?
After you qualify, you will be referred to one of our authorised local installers. The installer will arrange a suitable date and time to proceed with your boiler replacement.
How "Free Boiler Grant" works ?

Renewable Energy Grants
Oil and LPG, condensing or non-condensing boilers, can be replaced with an Air Source Heat Pump, regardless of the boilers age.
For mains Gas First Time Central Heating, the property must have been connecting to gas grid with a gas meter as on or before 31/03/2022. This must be evidenced via receipt of installation, a letter confirming the installation of the meter or a gas bill prior to 31/03/2022.
If there is no evidence of gas in the property prior to 31/03, ASHP is the only option for installation.
Electric Storage Heaters (ESH) can only be installed to off-gas properties that cannot have ASHP or Biomass installed.
Private Rented Properties
Private Rented Sector properties are qualifying again for certain grants under ECO4, but only if their EPC rating is E, F, or G. Such properties must always receive one of the following mandatory installations:
- Internal Wall Insulation
- First Time Central Heating
- Renewable Heating Like-for-like Gas boiler replacement is still not available for Private Rented Sector, the same as it was under ECO3 funding
