Voluntary organisations could see their gas and electricity bills fall because of a deal between NCVO and energy company LSI Utility.
Under the contract, the company uses bulk buying power to obtain low rates from national energy suppliers, which will be passed on to NCVO members.
LSI already supplies a number of charities, including Sue Ryder Care, Help the Aged and Shelter.
Chris Taylor, business development manager at NCVO said: "NCVO are delighted that LSI Utility have now made their services available to all voluntary organisations. We are always striving to offer the best deals to our members, as well as the sector as a whole, and this will undoubtedly ensure that organisations can now consider new ways to cut their energy bills."
The deal with LSI Utility is one of a number of shared purchasing deals for products and services negotiated by NCVO's business development team.
