West Sussex Trading Standards is offering to install call blocking devices free of charge to help stop nuisance calls.
It is hoped that the service will help stop elderly and vulnerable residents being targeted by fraudsters.
Residents need to match certain criteria to qualify for the devices, which are proven to block up to 98% of nuisance calls.
To apply for a call blocker, contact Trading Standards online at: www.westsussex.gov.uk/callblocker or call 01243 642124 (Option 2).
