The first ECO Scheme began in April 2013. The current free boiler scheme, ECO3, includes the Affordable Warmth Obligation scheme, but ECO3 is different from previous ECO schemes as it cutbacks on the promises offered beforehand and is limited to gas boilers only. This latest phase will run until March 2022 and gives households that missed out on the initial two ECO programs an opportunity to benefit from warm housing polices.
The main purpose of The Affordable Warmth Obligation is to aid more than one million homeowners in overcoming fuel poverty and to lower their gas bills.
If you qualify for an Eco free boiler grant, apply for one today so you don’t miss out on the government’s generous offer; old boilers significantly contribute to household expenses, but by installing an energy-efficient gas boiler your gas bills can be reduced by £100-£300 a year.
In an attempt to reduce the number of carbon emissions produced by energy companies, the UK Government has set targets for energy companies to meet. Therefore, under the Energy Companies Obligations (ECO) agreement, energy companies are obliged to provide UK homeowners with ‘primary measures’ to use less energy.
1. HOME HEATING COST REDUCTION (HHCRO): This scheme is designed to help households to heat their homes for less. Solutions include installing energy-efficient replacement boilers.
2. CARBON EMISSIONS REDUCTION OBLIGATION (CERO): This scheme includes improving heat retention measures in homes such as roof insulation and connections to heating systems.

  • In order to reach its targets, energy suppliers in the UK have been asked to help lower fuel consumption and reduce household energy bills by paying for A-rated boilers to be installed in qualifying households.
  •  The leading boiler manufacturers including Worcester Bosch, Vaillant, Baxi, and Gloworm have been working on innovative designs to produce energy-efficient boilers.
  •  UK homeowners are encouraged to install energy-efficient gas boilers.
  •  Under the Affordable Warmth Obligation, energy suppliers have agreed to install replacement boilers for free in households that cannot afford to purchase a new gas boiler.
  •  It is anticipated that around 230,000 households in the UK will qualify for a free boiler grant. However, the government aims to support over 1 million homeowners in total. Thousands of households that are classed as ‘vulnerable’ may also be entitled to heavy subsidies.
  •  Any contributions you may have to pay will be small. Householders that are eligible for free boiler grants have no obligation to pay back instalments. Furthermore, there are no complicated terms and conditions to be met other than the basic qualifying criteria.
  • Households that qualify for a free boiler grant will be entitled to install a new gas boiler together with heating controls where necessary. An energy assessment will also be carried out free of charge.
  • The amount of funding you will be entitled to will depend on your income, the energy efficiency of your home and the age of your existing boiler.
