Stone King has donated £10,000 to the Disasters Emergency Committee (DEC) appeal in aid of Ukraine.
Managing Partner Steven Greenwood said: “We feel that this is a really effective way of giving to large organisations that already have a presence on the ground and who can support those fleeing Ukraine.
“We have all been moved by the terrible events taking place and want to support this worthwhile appeal in an effective way as possible.
“We urge fellow businesses to do the same and note that our Government has matched donations up to £25m.”
Stone King is at Bateman House, Hills Road in Cambridge with its other offices in Bath, Birmingham, Bristol, Leeds and London.
