The British Red Cross is "exploring the market" for a framework IT hardware and peripherals agreement.
The charity has issued a prior information notice to inform the market of "an upcoming tender opportunity".
Under the agreement the British Red Cross says it wants PCs, laptops, thin client devices, tablets and peripherals supplied on a UK-wide basis.
The agreement will cover a two-year period. Interested parties have until 1 April 2014 to get in touch with the charity.
The potential value of the deal has not been disclosed. The British Red Cross says multiple contractors are being sought, but that the framework agreement is "not suitable for smaller suppliers".
