Will CGT be owed

We are selling our old house a year after buying our new one, the house has been empty since we bought the new property as it's taken a while to sell. Would we be liable for Capital Gains tax as it was the family home and has been empty whilst trying to sell. Thanks

Hi
There may be some to pay if it has taken more than 9 months for the property to sell:
Private Residence Relief (Self Assessment helpsheet HS283)
Thankyou.
