It’s shaping up to be a cold winter so gritting of roads and pavements may be necessary.
The council’s webpages on gritting are here: https://www.wandsworth.gov.uk/roads-and-transport/streets/road-gritting/road-gritting-how-we-prepare-for-winter/
You can request for your street to be gritted, or if your street should have been gritted and it has not been, by emailing email@example.com
There is also a map of grit bins in the borough here: https://maps.wandsworth.gov.uk/map/Aurora.svc/run?embedded=true&nocache=0.3080626783303324&script=%5cAurora%5cpublic.AuroraScript%24&=undefined&hide_layers=Housing,School,GP,TPO,Local_Plan,Plan_Live,Plan_Decided&x=528981.127&y=172342.144&scale=8192
There are two grit bins on Bedford Hill, at the junctions with Ritherdon Road and Culverden Road. As far as I can tell from this webpage: https://www.wandsworth.gov.uk/roads-and-transport/streets/road-gritting/grit-bins/ – this grit is for residents to use on their residential roads – so you are free to use it if you wish. I appreciate that lugging grit back to your front door is not ideal but could be an option if a quick fix is needed.
