If it's just for a visit they will need a standard visitor visa, which i'm guessing as you are on a travel site. The link below has information for a child travelling along
You can travel to the UK without an adult (someone over the age of 18).
Your parent or guardian will need to provide their:
written consent for you to travel to the UK
full contact details
They’ll also need to provide proof that you have somewhere suitable to live during your stay in the UK, including:
- the name and date of birth of the person that you will be staying with an address where you will be living
- details of your relationship to the person who’ll be looking after you
- consent in writing so they can look after you during your stay in the UK
