Domain names and professional email: a plain-English guide for UK businesses

Domains and email are the plumbing of your online presence: invisible when right, costly when wrong. They're also where small businesses get quietly overcharged, locked in, or undermined — often without knowing it. Ten minutes of plain-English understanding fixes all of that.

Choosing the domain

• .co.uk vs .com: for a UK-serving business, .co.uk is the natural choice and signals exactly who you serve; .com suits international ambitions. If both are free, register both and point one at the other — it's a few pounds to stop a competitor or copycat taking it.
• Keep it sayable. The phone test: can you say it aloud once and have someone type it correctly? Hyphens, numbers and creative spellings all fail that test.
• Your name beats keywords. "smithheating.co.uk" builds a brand; "best-boiler-repair-walsall.co.uk" looks like spam and helps rankings far less than people think.

What it should cost — and the renewal trick

A .co.uk typically costs a few pounds to around £15 a year; .com slightly more. Two things to watch: first-year teaser pricing that renews at several times the intro rate, and add-ons you don't need bundled at checkout. One add-on worth having: privacy/WHOIS protection, which keeps your personal details out of the public record — many registrars now include it free.

The one rule that protects your business

Own your own domain. Registered in your name, in an account you control, with your card paying renewals. Not your web designer's account, not your nephew's, not the agency's. Businesses genuinely lose their domain — and with it their email and their Google rankings — because it was registered by someone who moved on, or held hostage in a dispute. Whoever controls the domain controls your presence; make sure it's you. It's also the first thing on our choosing a web designer checklist for a reason.

Why info@yourbusiness beats gmail

An email at your own domain does three jobs a free address can't: it looks like an established business (which matters most in quotes and B2B), it advertises your website in every message you send, and it's independent of any one provider — you can move it anywhere because you own the domain. None of this is snobbery; it's trust signals, and buyers read them whether they realise or not.

Setting up professional email

Two good routes for most UK small businesses:

• Google Workspace or Microsoft 365 (from roughly £5–6 per user/month): proper mailboxes, calendars, storage and mobile apps. The right answer for teams and anyone living in their inbox.
• Registrar or host email (often a few pounds, sometimes bundled): fine for lighter use, though deliverability and spam filtering are usually a step behind the big two.

Avoid the false economy of forwarding only — where info@yourdomain silently redirects to a gmail address and you reply from gmail. Recipients see the gmail, and replies from the wrong address confuse threads and spam filters alike.

Five-minute checklist

• Confirm the domain is registered to you and you can log in to the registrar today
• Check the renewal date and price — set it to auto-renew on your card
• Register the obvious sibling (.com or .co.uk) if it's available
• Set up at least one real mailbox at your domain and retire the free address from your van, cards and listings
