About this section

What a domain does — and does not do

A domain is an address used by websites, email and other services. It does not contain the website and it does not automatically include email. DNS records connect the name to those services. The registration must be renewed according to the registry and registrar terms.

Choose the name for real-world use

Prefer a name that can be said, heard and typed without explanation.
Check spelling, common mishearings and awkward letter combinations.
Avoid adding a town, service or keyword unless it is genuinely part of the long-term brand.
Check trade marks, company names and existing businesses before committing.
Consider both the website address and the email address that staff will say aloud.

Choose an extension deliberately

Domain-extension decisions
Situation	Likely starting point	What to check
Mainly UK customers	.co.uk or .uk	Brand recognition, matching names and international plans
International audience	.com or a suitable country strategy	Availability, regional versions and brand protection
Regulated or specialist sector	Relevant restricted extension only if eligible	Eligibility and continuing compliance
Several defensive registrations	One canonical primary domain	Renewal cost and redirect management

Keep the registration recoverable

Use accurate registrant details, a monitored recovery email and multi-factor authentication where the registrar supports it. Record the registrar, expiry date and renewal method outside the registrar account. A domain is too important to depend on a single inbox or individual.

Where to go next

Use the detailed guides in this section for extension choice, registration, transfers, privacy and recovery. Do not register multiple variants until the primary name and ownership model are settled.

Test the name before committing

Use the candidate domain in a short practical exercise. Say it over the telephone, type it on a mobile keyboard, place it after hello@, and ask someone who has not seen it to write it down. Search for visually similar names and check whether another organisation could plausibly be mistaken for the business.

Do not delay registration indefinitely while chasing a perfect name. Once legal and brand checks are complete, a clear available name with secure ownership is usually better than a clever alternative that customers cannot remember.

Final publication check

Legal and brand-confusion checks have been completed.
Registrant, renewal and recovery details are business-controlled.
The primary extension and any defensive registrations have a written purpose.
