Update: Flood damage help
To help residents affected by the recent severe weather, Rochford District Council will collect any flood damaged items free of charge. Please call our Customer Services team on 01702 318111 or email customerservices@rochford.gov.uk with your details.
We also have special arrangements in place to deal with Council Tax queries from people who have had to move out of their home to allow flood damage repairs to be done. Residents are advised to contact our Revenues and Benefits team on 01702 318016 to discuss their individual circumstances.
