Flue issue

9 years ago

So moved into a new house and decided to change the backpanel/hearth on the fireplace to tiles.. On removing the backpanel I was greeted with a huge hole that was way bigger than the closure plate.. The backpanel had been sealed and used as a seal to cover this hole.
When the flue was installed the brickwork was taken out and flue blocks were installed... They are literally mm's deep leaving no room to cover across the hole and cement it over...
Anyone have any advice on how to cover this 12" gap safely?
