Most decisions about a new website can be changed later without too much pain — colours, wording, even the platform it's built on. Your domain name is the one exception. Change it years down the line and you lose search rankings, break bookmarks and email links, and confuse existing customers. Here's how to get it right the first time.
.co.uk vs .com vs the newer alternatives
.com is worth buying alongside your .co.uk if it's available and reasonably priced, even if you only redirect it to your main domain — it protects you from a competitor or unrelated business picking it up later and catching people who guess the wrong ending.
Newer extensions like .biz, .online or .services can look distinctive, but they still read as slightly unusual to a lot of UK customers and are worth avoiding as your primary domain unless the .co.uk and .com you actually want are both taken and unaffordable to buy from whoever holds them.
Brand name vs keyword domain
Worse, keyword domains often look less trustworthy to customers than a proper brand name, and they box you in if you ever expand your services or move location. A domain built around your actual business name is nearly always the better long-term choice, and it's what people will remember, search for directly and put on a van sign or invoice without confusion.
Length, spelling and the say-it-out-loud test
Before settling on anything, say it out loud to someone else and ask them to spell it back to you without seeing it written down. If they get it wrong, or ask "with a K or a C?", that's a real problem — it means every phone conversation and radio mention will lose some proportion of people who never find the site. This matters more than most people expect, particularly for businesses that rely on word of mouth or local advertising.
Mistakes worth avoiding
- Hyphens — hard to say aloud, easy to mistype, and they can read as slightly spammy to customers who've learned to associate hyphenated domains with lower-quality sites
- Numbers — ambiguous when spoken ("four" or "4"?) and best avoided unless the number is genuinely part of your established brand name
- Trademark clashes — always check the domain doesn't infringe an existing registered trademark before committing to branding, signage and marketing around it
- Overly clever wordplay — a pun that isn't instantly obvious in writing usually just confuses people typing it from memory
What's worth buying defensively
It's not usually worth going further than that. Buying dozens of speculative variations rarely pays for itself and just becomes an annual renewal bill for domains that sit unused.
What it actually costs
On our managed hosting plans, the domain itself, its renewals and its DNS configuration are all included as part of the monthly fee, so it's one less thing for a business owner to track and remember to renew each year — a surprising number of businesses have lost their domain simply because a renewal email went to an old inbox nobody checked.
Who should actually own the registration
If you're not sure whose name your current domain is registered under, a WHOIS lookup or your registrar's account settings will usually confirm it, and it's worth checking sooner rather than later. We go into the wider setup around domains, DNS and hosting in our jargon-free guide to domains, DNS and hosting, and it's something we set up correctly, in the client's own name, on every website we build.
Common questions
Should a UK business use .co.uk or .com?
If you serve UK customers, .co.uk is the natural choice and carries no ranking disadvantage domestically. Buy the .com too if it's available and affordable, and redirect it to your main domain.
Do keyword domains still help SEO?
Barely. An exact-match domain like cheapplumbercambridge.co.uk gave a real advantage a decade ago. Today it's close to worthless as a ranking factor and often looks less trustworthy than a proper brand name.
Should hyphens or numbers go in a domain?
Avoid both where you can. They're hard to say out loud, easy to mistype and often read as spammy. If the clean version is taken, a slightly different brand word usually beats a hyphenated compromise.
What does a domain cost in the UK?
A .co.uk is typically £8-£15 a year and a .com £10-£20. On our managed plans the domain, renewals and DNS are handled as part of the monthly fee.
