Coach HarmonyIf you have a business idea and live in the UK you don’t need to worry about domain name costs. You can get 2 free domains, no strings attached. Just two free names. You can also buy .com for £1.99. Startup for next to nothing if you can use a website builder or WordPress. Hosting is separate. You can use the hosting provided. Or if you already have a host, you can still claim a free domain!
You can also claim a free .org.uk if you’re an organisation.
