Charities that offer innovative energy-saving solutions or energy support and advice to vulnerable customers will soon be able to apply for a share of a £2.5m funding pot.
The money is being given out by the Energy Saving Trust as part of the Energy Industry Voluntary Redress Scheme, a fund made up of voluntary payments from companies that have broken rules set by the energy regulator Ofgem.
The funding round is due to open on 15 October and will run until 16 November.
A spokesman for the EST said the trust had not set a limit on the size of individual grants.
Money can be used for capital or revenue funding and eligible projects include those that engage and offer support or training to vulnerable customers with energy issues, installation of innovative energy saving or renewable energy measures or in-home energy safety advice and measures related to energy systems.
The application guidance says other energy-related projects will be considered, but not those that duplicate existing projects or which could be funded elsewhere.
A previous tranche of funding distributed more than £280,000 to six schemes, including one that encourages good energy behaviours through cooking, a pilot to test heating controls for the visually impaired and a project to install a district heating system.
Mike Thornton, group director of operations at the Energy Saving Trust, said: "This is a significant pot of money and we’re looking forward to welcoming applications from across the country that can help deliver benefits to energy consumers.
"The overarching aim of the Energy Redress Scheme is to distribute available funds to support energy consumers in vulnerable situations and the development of products or services that will provide a benefit to certain groups of energy consumers."
Charities intending to apply for grants are required to register their interest at least two weeks before the application closing date on the fund’s dedicated website.
The successful schemes are expected to be announced in the new year.
