How to choose a good domain name for a UK website or business: .uk vs .co.uk vs .com, keeping it short and clear, trade mark checks, registering in your own name, renewal costs, privacy, and avoiding common traps.
Your domain name is your address online. It appears on cards, emails and adverts, and changing it later is painful. A little thought up front avoids an awkward name, a renewal shock, or a dispute with someone else's trade mark.
Choose the right ending
- .co.uk is the long-established UK choice and is widely recognised and trusted by UK customers.
- .uk is shorter and also managed by Nominet, the UK registry.
- .com is the global default and suits businesses selling internationally, but good names are often taken.
- .org.uk is commonly used by charities and non-profits.
- New endings such as .shop, .tech or .london can work, but are less familiar and often cost more to renew.
If budget allows, register both the .co.uk and .uk (or .com) and redirect one to the other, to protect your name.
Make it easy to say and type
- Keep it short, ideally under about 15 characters.
- Avoid hyphens and numbers, which are easy to get wrong when spoken.
- Avoid awkward letter combinations that create unintended words when run together.
- Say it out loud: if you have to spell it every time, think again.
- Choose something that won't date or box you in if your business grows.
Check you're allowed to use it
Search the UK Intellectual Property Office's trade mark database and Companies House for similar names. Using a domain that matches someone else's trade mark can lead to a dispute. Nominet runs a dispute resolution service for .uk domains, and ICANN's UDRP covers .com and other generic endings. Also check social media handles are available.
Register it properly
- Register it in your business's or your own name, not your web designer's or an employee's.
- Use an email address you control long term.
- Turn on auto-renew and two-factor login.
- Keep contact details up to date. For .uk domains, inaccurate details can lead to suspension.
Watch the costs
Many registrars offer cheap first-year prices and higher renewals. Check:
- the renewal price, not just the first-year price;
- whether privacy or DNS management cost extra;
- transfer-out fees and restrictions;
- whether email or hosting is bundled, and what happens if you cancel it.
Premium domains, names the registry or a reseller has priced higher, can cost hundreds or thousands of pounds, sometimes with higher renewals too.
Privacy
Public WHOIS details for many domains are now redacted for individuals following data protection rules. For .uk domains, Nominet doesn't publish individuals' addresses by default. Check your registrar's settings.
Transferring later
You can usually move a domain to another registrar. For .uk domains, you change the domain's IPS tag to the new registrar's. For .com and other generic domains, you need an authorisation code, and transfers may be blocked for 60 days after registration or certain changes. Unlock the domain and keep email access during the move.
Avoid these traps
- letting a domain expire: it may be grabbed by someone else and resold;
- scam "renewal" letters or emails from companies that aren't your registrar;
- registering a name similar to a well-known brand, which can lead to disputes;
- choosing a domain only for keywords: brandable names usually work better long term.
Frequently asked questions
Does the domain name affect search rankings?
Only a little. Content quality matters far more than keywords in the domain.
Can I buy a domain someone else owns?
You can make an offer, often through a broker, but be cautious and use an escrow service.
