The dad-of-two was taken by ambulance to the family home on Wednesday April 7.
It is believed Derek, 53, was taken off machines but will need round-the-clock care now that he’s home.
But medics warned Good Morning Britain presenter Kate that her husband still has a long way to go in his recovery.
The TV star is reportedly thrilled to have Derek home with their two children, Darcey, 15, and 11-year-old Billy, according to the Mirror.
A friend told The Sun: “Kate’s dreamt of this day for so long, and can’t thank wonderful NHS staff enough.”
They added: “The children, who have been so remarkably resilient, have been so, so happy to have their dad home.
“There have been a lot of happy tears from everyone.”
He was later put into an induced coma that lasted 13 weeks – which he woke up from in July.
Kate has been open with fans that Derek’s recovery will be a slow process as the virus “attacked everything”, leaving him with clots in his lungs, holes in his heart and made him diabetic, and doctors have warned Kate that Derek might never fully recover from the damage done to his body.
The devastating news of Derek’s condition saw Kate take an extended leave from GMB to be with her family, before defiantly returning to the show in July with her head held high.
At Easter, Kate spoke about how difficult it was to go through her second Easter without husband Derek.
“Happy Easter everyone,” she started off the heartfelt post.
“It’s so hard that it’s the second we’ve lived through in Lockdown/restrictions and of course, our second without Derek home with us.
“But he is still here so we have so much to give thanks for and there are lots to hope for isn’t there.”
Kate’s recently made an ITV documentary, named Finding Derek, in which focused on her husband’s battle with coronavirus.
She is also releasing a book on April 29 called The Power Of Hope: The moving memoir from TV’s Kate Garraway.
The memoir is her personal diary from the tough period of her life and she hopes her honest words will be helpful to other families who are facing the struggles she and her family have in the last year.
