About Free Boilers

Free Boilers is intended as a guide to applying for grant funding for free gas boiler replacements via the UK Government backed Energy Companies Obligation (ECO) grant scheme. ECO boiler grants are funded by the major UK energy suppliers. This service is completely free to use.

You can use Free Boilers to find out if you qualify and apply for a replacement boiler, home insulation or a pay monthly boiler finance plan. If you qualify for any of these carbon saving services your application will then be passed on to a Government approved and certified installer.

During your application you may be asked for data relating to your personal circumstances including your property status and any benefits you claim. This data will not be shared with any parties other than those involved in the application, survey and installation of any measures or products for each individual application.
