The Severn Trent Trust Fund is planning to share its experience of awarding small grants to help poor people pay their fuel bills by inviting other utility companies to do the same.
The trust fund has awarded £12m to more than 40,000 disadvantaged families living in the Midlands area since the fund was established in 1997.
The organisation has also awarded almost £2m to organisations that provide advice on debt management.
Stuart Brayley, chief executive of the trust, said: "We will promote and use our expertise to assist other utility companies in creating similar charitable giving in the face of rising fuel and water bills."
Further details of the scheme will be announced next month.
