CGT on Foreign Residential property sale

Hi HMRC, I have just (this week) sold a property in Ireland and have made a capital gain.
The long and short of this is I have paid circa €50,000 CGT in Ireland and I have a CGT Liability in the UK of circa £40,000.
I understand i can claim the forign CGT paid to offset my CGT liability in the UK and I will seek professional tax advice on this.
My question is as follows.
When do i need to declare the sale to HMRC?
i understand if i sold a UK property i would need to declare and pay within 60days.
However if it's an Irish property do i need to do this or do i just fill in a self assessement for the 24/25 tax year.
Thanks
