Last year Lambeth Council invited residents to become snow wardens to help keep pavements and side streets clear in the event of snowfall but Waterloo and Kennington residents have failed to respond to the call.
Snow wardens are given basic training and provided with a grit bin and supply of salt, shovels, hi-visibility vests and gloves.
Whilst council contractors concentrate on gritting main roads and pedestrian routes, volunteers are invited to help keep residential areas clear during and after snowfall.
The council launched the call for volunteers in September and claims to have "groups of snow wardens throughout the borough" but a map published on the Lambeth website shows that by mid-December no snow wardens had been recruited in the northernmost two wards of the borough: Bishop's (Waterloo) and Princes (Kennington).
Elsewhere in Lambeth more than 200 snow wardens have been appointed compared to an expected take-up of 300.
