Twelve years ago (Icons passim) I worked with DEC on their Haiti Appeal. I thoroughly recommend them if you have got a couple of quid spare to throw the way of Ukrainian refugees.
The DEC brings together 15 leading aid charities to raise funds quickly and efficiently at times of crisis overseas. In these times of crisis, people in life-and-death situations need our help and our mission is to save, protect and rebuild lives through effective humanitarian response.
ActionAid, Action Against Hunger, British Red Cross, CAFOD, CARE International, Christian Aid, Concern, Age UK, International Rescue Committee, Islamic Relief, Oxfam, Plan UK, Save the Children, Tearfund, World Vision.
What particularly impressed me in practice was its distributed, collegiate structure which enabled resources to be directed to sectors that might be overlooked by an overreaching, overweening, blunderbuss, top-down approach. I distinctly remember Save the Children focussing on, ahem, Haitian children, Age UK concentrating on Haitian pensioners etc. and already having contacts, on the ground, with equivalent local organizations.
