Choosing a domain name is one of the first decisions you make when taking your business online, and it is worth getting right. A good domain name is easy to remember, easy to spell, and tells people something about what you do or where you are based. A bad one creates confusion, costs you customers, and can be surprisingly difficult to change once you have built a brand around it.
The good news is that picking the right domain name is not complicated. You just need to know what to look for — and what to avoid.
Keep It Short and Easy to Spell
Your domain name will appear on your business cards, your email signature, your van, your social media profiles, and anywhere else you promote your business. If it is long, awkward, or easy to misspell, people will get it wrong — and when they get it wrong, they end up on a competitor's site or a blank page.
Aim for something between one and three words. Shorter is almost always better. If you can say it out loud and a stranger can type it correctly first time, that is a good sign.
Avoid hyphens, numbers, and unusual spellings. Hyphens in particular cause problems: if you tell someone your website is "blue-sky-cleaning.co.uk," half of them will try "blueskycleaning.co.uk" and wonder why it does not work. Numbers are similarly confusing — does "4" mean the digit or "for"?
Use a .co.uk Extension If You Serve UK Customers
For most UK small businesses, a .co.uk domain is the right choice. It signals to both customers and Google that you are a UK-based business serving UK customers. If someone searches for a local service and sees a .co.uk result alongside a .com result, the .co.uk often feels more relevant and trustworthy.
That said, there are situations where .com makes sense — if you serve international customers, if the .co.uk version of your preferred name is already taken, or if you are building a brand that you want to feel global. In those cases, .com is still the most recognised and trusted extension worldwide.
Avoid less common extensions like .biz, .info, or .online unless you have a specific reason. They tend to look less professional and can make customers question whether the business is legitimate.
If your preferred .co.uk is taken, check whether the .com is available — or consider a slight variation. Just do not stretch too far. A domain that only sort of sounds like your business name is worse than no website at all.
Include Your Business Name, or What You Do, or Both
Most domain names follow one of three patterns:
Your business name: if your company is called Henderson Electrical, then "hendersonelectrical.co.uk" is the obvious choice. It reinforces your brand and makes you easy to find by anyone who already knows your name.
What you do: if your business name is not particularly memorable or does not describe what you offer, a descriptive domain can work well. "plumbingservicesleeds.co.uk" or "weddingphotographybristol.co.uk" tells Google and your customers exactly what you do and where.
A combination: if your name and your trade are both short, combining them can work — "smithsplumbing.co.uk" is better than either alone because it is both branded and descriptive.
Which approach is right for you depends on how well known your business name is, and how important it is to rank for search terms that include your location or trade. If you are just starting out and nobody knows your name yet, a descriptive domain often has a slight SEO advantage. If you have an established brand, stick with your name.
Check for Conflicts and Trade Mark Issues
Before you register a domain, search for it online. If another business — particularly in the same industry — is already operating under a very similar name, that is a problem. You do not want to be confused with a competitor, and in some cases using a name that is too similar to an existing trade mark can create legal issues.
Also check the major social media platforms. Even if you are not planning to use every platform, securing your business name on Instagram, Facebook, and X costs nothing and prevents someone else from taking it later. Ideally, your domain name and your social handles should match, or be close enough that customers can find you on any platform.
Register It as Soon as You Have Decided
Domain names are cheap — typically between £10 and £20 a year for a .co.uk — and they can be snapped up at any time. If you have settled on a name you like, register it now rather than waiting until your website is ready. You do not need a website to own a domain; you can park it and point it at your site when the time comes.
Use a reputable UK registrar such as 123 Reg, Fasthosts, or Namecheap. Avoid registrars you have not heard of, especially those offering suspiciously cheap first-year pricing with steep renewal costs hidden in the small print. Always check what the renewal price will be, not just the initial offer.
Make sure the domain is registered in your name (or your company's name), not your web designer's. Some agencies register domains on behalf of clients but hold them in their own account — which means if you ever move to a different designer, extracting your domain can become complicated. Your domain is a business asset; make sure you own it.
What If Your Preferred Name Is Already Taken?
It happens to almost everyone. If "smithsplumbing.co.uk" is gone, here are a few things to try:
- Check whether "smithsplumbing.com" is available
- Try adding your location: "smithsplumbingleeds.co.uk"
- Add a descriptor: "smithsplumbingservices.co.uk"
- Use an alternative but still descriptive name that is available
If the domain you want is taken but not actively in use, you can sometimes contact the owner and buy it directly. Domain marketplaces like Sedo also list domains for sale. Prices vary enormously — anywhere from £50 to thousands of pounds — so it is only worth pursuing if the name is genuinely important to your brand.
What you should not do is choose a name that is so different from your business that it creates confusion. If none of the variations feel right, it may be worth reconsidering your business name before you build your brand around a domain that does not quite fit.
Get the Basics Right Before You Build
Your domain name is the foundation everything else sits on. Getting it right at the start saves you from expensive and disruptive rebrands later. Take the time to think it through, check availability across domains and social media, register it in your own name, and go with something simple, memorable, and accurate.
Once you have your domain sorted, the next step is building a website that does it justice. If you are ready to get online or want advice on where to start, get in touch — we help UK small businesses get online with websites that are fast, professional, and built to bring in customers.
