If you buy cables from a retailer that you know and trust - a High Street name rather than buying from a third party via an online marketplace - then they will conform to British Standards and be safe.
However, if you are not sure as to what you should buy, please use a registered electrician to supply the cables and install sockets. You can find one local to you here.
