Receiving direct mail (often called junk mail) in the deceased's name can be distressing.
There are free services which can dramatically reduce the amount of direct mail will be delivered. It is a good idea to do this because it helps reduce the risk of identity fraud using the identity of the person who died as well as reducing the number of companies you will have to contact individually.
The services are funded by responsible companies who use direct mailing as they would prefer not to cause unnecessary distress to bereaved people.
Bereavement Advice Centre offers a free junk mail suppression service.
You should be aware that it can take a few weeks for the services to become fully effective as companies prepare mailings a month or more in advance.
These services should not stop correspondence from companies/services with whom the person who died had a relationship e.g. their bank or telephone provider. The aim is to stop post that is mostly advertising for products and services.
