The cold snap has led to a 20% increase in queries about unified communications from small and medium companies, says hosting firm Outsourcery.
With many people struggling to get to work, UK SMEs could lose up to £230m, said the Forum of Private Business. This was increasing interest in remote working via online technologies, said Outsourcery joint CEO Piers Linney.
Linney said Outsourcery itself had to shut down all its offices in Bury, Leicester, and London due to the bad weather, but its operations were unaffected as staff worked from home.
More firms were seeing the value of real-time communication tools such as instant messaging, presence information, voice and video conferencing, Live Meeting for group discussions and document sharing, he said.
The tools allowed bosses to see where staff were and what they were doing, and to contact them in the most appropriate and time-efficient way, he said.
"The current cold snap will only underline how being able to connect with your colleagues whenever and wherever they are means an increase in productivity company-wide," he said.
