Open Namecheap and search
Open the Namecheap domain search page, type your preferred domain into the search box, and click Search. A short business name is usually easier for customers to remember and type.

Namecheap guide
Buy the domain you want to use for your business website. This guide keeps the process focused on the domain itself.
Your domain is the web address customers type to find your business, such as carwashexample.co.uk. It looks more professional than a generic link, is easier to share on Google, social media, business cards, and invoices, and it stays yours as your business grows.
Open the Namecheap domain search page, type your preferred domain into the search box, and click Search. A short business name is usually easier for customers to remember and type.
If the domain is available, click Add to cart on that exact domain. Namecheap may also show similar names such as .com, .net, or .org options. Only choose those if you specifically want them.
Namecheap may suggest hosting, WordPress hosting, SSL, email, logos, or other extras. For this setup, keep it simple and continue with the domain only.
Keep the registration term simple, such as one year, unless you already know you want a longer term. If domain privacy is included, leave it enabled because it helps keep personal contact details away from public WHOIS lookup results.
If Namecheap asks you to log in, sign in with your Namecheap account. If this is your first Namecheap purchase, choose Sign up and create an account using an email address where Namecheap can send account and purchase emails.
Enter the required contact and payment details, then complete the purchase. You do not need to buy hosting, website builder, business email, PremiumDNS, or other add-ons just to register the domain.
After checkout, open Domain List in your Namecheap account. This is where the new domain appears and where you can manage it later.
Once the domain is registered, the next step is connecting it to your business website. Open the domain setup screen in your admin workspace when you are ready to point the domain to the website.
