Giffara

Can anyone help me please, I have just bought a house in which I reside in it and it is the only one property I own. I have only been living in it for 6 months and wish to sell it. I am a uk resident, the house and garden is less than half an acre, it is not used as a business, or rented out, I have not lived aboard or have at any time. Would I have to pay capital gains tax if i make any profit on it. I would be grateful for any information or advice thanks.
