Do I Need a Professional Email Address for My Small Business UK?

If you have just registered a UK limited company or started trading as a sole trader, you are probably wondering whether your Gmail account is good enough. Since the 4th of March 2024, every UK limited company must give Companies House a registered email address by law. This article covers what is actually required, what is just recommended, and what it costs.

Do I legally need a professional email address for my UK limited company?

No, the law does not require a custom domain email. Every UK limited company must give Companies House a “registered email address” since the 4th of March 2024, but a monitored Gmail account satisfies that rule.

The requirement comes from the Economic Crime and Corporate Transparency Act 2023, which added section 88A to the Companies Act 2006. New companies must provide an email at incorporation. Existing companies must provide one at their next confirmation statement filed on or after the 5th of March 2024.

The legal test is whether the address is “appropriate”. That means Companies House emails reach a real person at the company. Gmail meets that test. A custom domain is not legally required.

The law cares about delivery. Customers, suppliers and banks care about a separate question, which is where the “professional” part comes in.

What counts as a “professional” email address?

A professional email address uses your own domain name, such as you@yourbusiness.co.uk, rather than a free service like Gmail or Outlook.

The setup is simple. You buy a domain, then connect an email service to it. Every email you send shows your domain in the address, which matches your website, invoices and branding.

There are two parts to the cost. A .co.uk domain costs roughly £6 to £22 a year from a UK registrar. The mailbox itself costs from around £5.75 per user per month with Microsoft 365 Business Basic, or £5.90 with Google Workspace Business Starter (both ex VAT, May 2026 prices).

If you already have a website, you almost certainly have a domain. Connecting an email to it is the next step.

Do customers really judge businesses by their email address?

Yes. GoDaddy reports that customers are 9x more likely to choose a business with a professional email address over one using a free service like Gmail.

UK research backs the broader point. A 2023 Statista survey found 67% of UK consumers said spelling mistakes were among the top three things that stopped them engaging with a branded email. Missing branded signatures and poor formatting were the next two.

The effect is felt most in three places. New customers comparing quotes assume mybusiness@gmail.com is a side hustle. Suppliers and trade accounts can refuse credit applications from generic domains. Bank and HMRC correspondence looks more credible from an address that matches your website.

Plenty of UK businesses trade from Gmail and do well. But if you want to be taken seriously from day one, this is one of the cheapest credibility upgrades available.

Do sole traders need a professional email address too?

Sole traders are not bound by section 88A. The rule only applies to limited companies. But the customer credibility argument applies just the same.

A sole trader using suzy@gmail.com for plumbing enquiries is harder to verify than one using suzy@suzysplumbing.co.uk. The cost is the same as for a limited company. For most sole traders, one mailbox is enough.

If you are still deciding whether you need a website at all, we have covered that in detail. Once you decide the website is worth it, the email comes with it.

One thing most builders will not flag: legal compliance. Whether you build the site yourself or have it done for you, your website needs a privacy policy, cookie notice, terms and conditions and the right business information in the footer. DIY builders rarely check whether yours are complete. Run an existing site through our free website compliance checker to see what is missing.

How much does a professional email address cost in the UK?

Roughly £80 to £110 a year for a single mailbox including the domain, paid annually.
The breakdown:

• Domain (.co.uk): £6 to £22 per year, depending on registrar.
• Mailbox: from £5.75 per user per month (Microsoft 365 Business Basic) or £5.90 (Google

Workspace Business Starter), ex VAT.
That is the standalone price. Bundled setups that include a mailbox and domain in the website price can work out cheaper for the first year, especially if you would otherwise be paying for hosting, a mailbox subscription and a domain separately.

What is the simplest way to set up a professional email for my business?

Bundle the email, the domain and the website together so the technical setup is done for you.

If you are sorting it yourself, there are three steps. Register a domain. Connect an email service like Google Workspace or Microsoft 365. Configure the DNS records so emails do not land in spam. That takes an afternoon if you have done it before, and a weekend if you have not.

If you also have a UK limited company to register, our guide to hiring someone to build your website covers the full picture. The honest answer is the same as the answer here. If you would rather spend your time on your business than on DNS records, hand it over.

Setting up the domain, email and website together also makes meeting your GDPR obligations easier. One footer, one consistent contact email, one set of records.

Set it up properly from day one

If you decide a professional email is worth it, the cleanest route is to buy the domain, the email and the website together.

Duport’s website build starts from £360. Mention this article when you get in touch and we’ll honour the £144 rate. That covers a mobile-friendly site, live in 72 hours, with about 30 minutes of your time.

For those also registering a limited company, the full bundle is £244 upfront. That covers company formation, your website, email, and seven compliance tools together. Annual renewal is £94.

You can switch later if you would rather sort it yourself for now. Section 88A only requires a working email, not a custom one.

FAQs

• Can I keep my Gmail and add a custom domain email later?

Yes, most providers let you forward your domain email to your Gmail inbox, so you read mail in one place but send from the professional address.

• Do I need a Google Workspace or Microsoft 365 subscription, or is one mailbox enough?

One mailbox is enough for most sole traders and new limited companies, costing roughly £70 a year ex VAT on either platform.

• Will customers really notice if I send invoices from Gmail?

Bigger customers, trade accounts and suppliers asking for credit terms are the ones most likely to notice; consumers asking for a quick quote often will not.

• What email goes on my Companies House confirmation statement?

The registered email address you give Companies House must be “appropriate” under section 88A, which means a real person at the company actually reads it.

• Is my Wix or Squarespace website legally compliant in the UK?

Not automatically. UK law requires your website to include a privacy policy, a cookie notice, clear terms and conditions, and specific business information (such as your registered company name and number if you’re a limited company). Most website builders include template pages for some of these, but they don’t check whether your content is accurate or complete.
