As of 13 August 2026, AI can only partly check whether a brand name's domain is available.
This still needs a person who signs their name to it.

What the alternative costsA registrar's domain search is the practical alternative, but no registrar or registration price is specified here.
If this goes wrong: you assume a domain is available when it has already been registered, then correct the shortlist before buying or publishing anything.

The route this page recommends
A person who owns the outcome does this end to end, worth it when the failure is dear.
Do it yourself
Second choiceA chat interface, no skill needed, and roughly 5 minutes until you can act on the result.
How to actually do it
- Write the exact proposed brand name, including spacing, punctuation and any intentional spelling, in a short list.
- Choose the domain extensions relevant to the UK business, such as .co.uk, .uk and .com, and add them to the list.
- Paste the prompt and the completed list into a chatbot, then provide a live registrar search page or screenshot if the chatbot cannot access current web results.
- Open the registrar's search page and search every exact domain returned by the chatbot, recording the current result for each extension.
- Remove any domain marked unavailable or unclear, and compare the remaining spellings character by character with the proposed brand name.
- Before registering a domain, search the UK government's company information and trade mark resources separately because an available domain does not establish that the brand name is legally clear.
Prompt
I am checking domain availability for a brand name. Brand name: [EXACT BRAND NAME]. Check these extensions: [.co.uk, .uk, .com, OTHER]. Use only current live search results or a registrar page that I provide, and do not infer availability from memory. For each extension, report the exact domain, whether the live result says it is available, unavailable or unclear, and the source page or lookup result. If you cannot access a live lookup, say that plainly instead of guessing. Also flag domains that differ from the brand name because of spelling, hyphens or added words. Do not treat domain availability as proof that the name is clear for UK trade mark, company-name or social-media use.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong
- Cannot guarantee a live result when it lacks access to a registrar's current search.
- Cannot reserve the domain while you are considering it, so another person can register it first.
- Cannot establish that the name is clear for UK trade mark, company-name or social-media use.
- Cannot judge whether a small spelling change will be memorable, pronounceable or confusing for customers.

FAQ
- Can ChatGPT check if a domain name is available?
- Partly. It can help check a live registrar result or organise a list of domains, but it should not guess from its stored knowledge because availability changes. Enter each exact domain into a registrar before relying on the result.
- How do I check if a .co.uk domain is available?
- Search the exact name on a registrar that offers .co.uk domains and read the current availability result. You can ask AI to organise several names, but the registrar's live result is the one to confirm.
- Can AI tell me if a brand name is legally safe?
- No. An available domain does not show that the name is clear for UK trade mark, company-name or other commercial use. This is not professional advice, and a serious naming dispute needs a trade mark solicitor or other qualified trade mark professional.
- Should I buy the domain if AI says it is available?
- Only after you confirm the exact domain on a registrar's live search page. Check the UK trade mark and company-name position separately, then register it promptly if the result and your wider checks are satisfactory.
