The suggested 'loan service' was included in a report the LMC sent to Bromley PCT after February's severe weather.
Jackie Peake, committee liaison executive at Bromley LMC, said doctors suggested how services could respond better to similar weather in the future.
'Instead of struggling in and doing the normal commute, you report for duty at the closest practice,' she said.
This would require coordination at a central level, said Ms Peake, so that clinicians knew where to go if they were unable to get to their usual practice.
A spokeswoman for Bromley PCT said the LMC report would be incorporated into the flu pandemic and emergency planning arrangements.
