What is the difference between .co.uk and .com ?
While .co.uk is aimed at UK audiences, .com is broader and works for any business, anywhere. It’s often the go-to for international businesses or those who don’t want to appear limited to just one market.
That said, .co.uk domains are often cheaper and easier to find than .com domains. That’s why we recommend any UK business register a .co.uk.

Can I buy both a .com and .co.uk?
Absolutely! Getting both helps protect your name, keeps your branding consistent, and makes it easier for people to find you. If both are available, snap them up. Short, catchy domains go fast – but specific names like yourbusiness.co.uk are often still available.
What is the difference between .co.uk and .uk?
The .uk domain extension launched in 2014 as a shorter, simpler alternative to .co.uk. It’s modern, easy to type, and still proudly British. Because it’s newer, there’s often more availability. And like .co.uk, it’s open to everyone and widely trusted. Both options work brilliantly for British businesses.
