The charity Action on Empty Homes runs its prime publicity event between 15th and 21st October this year. It's website states:
National Empty Homes Week 2018 is scheduled to run from the 15th to 21st October. Every year local authorities, housing providers, community-led organisations and others see Empty Homes Week as an opportunity to organise events and put out information so that people know about their work to tackle empty homes. Empty Homes Week is also the chance to celebrate successes and reflect on what more needs to be done to bring empty properties back into use to help meet housing needs.
If you want to sponsor the event, or you simply want to find out more details, please email firstname.lastname@example.org
