Business Email Hosting vs Google Workspace vs Microsoft 365: Which Is Right for Your UK Business?

When it comes to setting up professional email for a UK small business, three main options tend to come up: a straightforward business email package through your hosting provider, Google Workspace, or Microsoft 365. Each has a genuinely different approach, and the right choice depends more on what you actually need than on which is simply “the best”.

This guide compares all three honestly, covering cost, features, and who each option tends to suit best, so you can make a decision based on your business’s actual requirements rather than marketing claims.
Email rarely sits on its own. If you are reviewing your setup as a whole, our guide to business website hosting covers how email and web hosting are best bundled. If your website already lives on Wix, Squarespace or Lovable and you just want cheaper email, see our guide to using Switchweb for email only.

What Each Option Actually Is

Business email hosting

This is a straightforward email service tied to your domain, typically provided alongside web hosting or as a standalone email package. It gives you a professional email address (such as hello@yourbusiness.co.uk), accessible via webmail or any standard email app, with no additional productivity tools bundled in.

Google Workspace

Google Workspace (formerly G Suite) provides Gmail-based email on your own domain, alongside Google’s wider productivity suite: Google Docs, Sheets, Slides, Drive storage, Meet for video calls, and shared calendars, all integrated together.

Microsoft 365

Microsoft 365 provides Outlook-based email on your own domain, alongside Microsoft’s productivity suite: Word, Excel, PowerPoint, OneDrive storage, Teams for video calls and chat, and shared calendars.

Cost Comparison

This is often where the decision starts, and the gap can be significant depending on what you actually need.

Business email hosting

Typically the most affordable option, often priced per mailbox per month, sometimes included at no extra cost as part of a web hosting plan. For a small number of mailboxes, this can cost a fraction of what Google Workspace or Microsoft 365 would charge for the equivalent number of users.

Google Workspace and Microsoft 365

Both are typically priced per user per month, with several tiers offering different storage allowances and additional features. Even at the entry-level tier, the per-user cost is usually noticeably higher than basic business email hosting, reflecting the much wider set of tools included.

What this means in practice

For a business of, say, five people, the total monthly cost of Google Workspace or Microsoft 365 can be several times higher than basic business email hosting for the same number of mailboxes. Whether that difference is worth it depends entirely on whether you actually need and use the additional productivity tools.

Feature Comparison

Storage

Business email hosting plans typically include a set amount of mailbox storage, often generous enough for years of typical business email use, though usually less than the larger allowances bundled with Google Workspace or Microsoft 365, which also include separate cloud storage (Drive or OneDrive) for documents.

Collaboration tools

This is the clearest differentiator. Google Workspace and Microsoft 365 both include real-time document collaboration, shared drives, video conferencing, and team chat tools, none of which are part of standard business email hosting. If your team regularly collaborates on documents, holds video calls, or needs shared file storage, this is a significant practical advantage.

Familiarity

Many people are already familiar with Gmail or Outlook interfaces from personal use, which can shorten the learning curve for teams adopting Google Workspace or Microsoft 365, compared to a webmail interface they may not have used before.

Mobile apps and integration

Both Google Workspace and Microsoft 365 offer polished, well-maintained mobile apps with deep integration across email, calendar, and documents. Business email hosting can still be accessed via any standard email app on mobile, but without the same level of integrated calendar and document features.

Who Each Option Tends to Suit Best

Business email hosting suits you if:

• You primarily need professional email addresses, without requiring built-in document collaboration or video conferencing tools
• You already use other tools for documents (such as desktop Office software) and file storage (such as a separate cloud storage service)
• You are a sole trader or very small team where shared collaboration tools are not a priority
• Keeping monthly costs as low as possible is a priority, particularly for an early-stage or budget-conscious business

Google Workspace suits you if:

• Your team already uses Gmail and Google tools personally, making the transition more familiar
• You collaborate heavily on documents in real time, with multiple people frequently editing the same file
• You want straightforward video conferencing built directly into your email and calendar workflow

Microsoft 365 suits you if:

• Your team already relies on Word, Excel, and PowerPoint, and you want these properly licensed and integrated with email
• You need Teams for video calls and internal chat, particularly if working with other organisations that also use Microsoft tools
• Your business has more complex IT requirements that benefit from Microsoft’s wider ecosystem of business tools

A Hybrid Approach

It is worth noting that these options are not always mutually exclusive. Some businesses use straightforward business email hosting for cost-effective email addresses, while separately subscribing to standalone versions of document or video conferencing tools only for the team members who genuinely need them, rather than paying for the full bundled cost across an entire team.

This can make sense if only part of your team needs heavy collaboration features, while others (such as those mainly sending and receiving email) do not need the full productivity suite. It is also a common approach for businesses whose website sits on Wix, Squarespace or Lovable: the website stays where it is, and email moves to a dedicated, lower-cost host. Our guide to using Switchweb for email only alongside Wix, Squarespace or Lovable walks through exactly how that works.

How to Evaluate Any Provider

Whichever of the three routes you lean towards, the same checklist separates a good provider from a poor one. Work through these before committing:

• Mailbox storage. Check the actual per-mailbox allowance rather than assuming “unlimited” means infinite. Most providers cap storage per mailbox even on plans marketed as unlimited mailboxes.
• How you are charged. Per mailbox, per user, or per domain. This is the single biggest driver of cost as a team grows, and it is where the three options diverge most sharply.
• Authentication support. SPF, DKIM and DMARC are what stop your legitimate email being filtered and stop others spoofing your domain. Any serious provider supports all three.
• Client and device support. Confirm IMAP, so mail syncs properly across devices rather than living in one inbox, and check that webmail, mobile and desktop clients such as Outlook all work.
• Data location. Where the mail servers physically sit. UK or EU-based servers simplify GDPR considerations, though your own data handling practices matter more broadly.
• Migration assistance. Moving mail and contacts without losing anything is fiddlier than it sounds. Ask whether it is included or chargeable.
• Retention and export. How easily you can get your mail out again if you leave. This is rarely advertised and worth asking about before you are locked in.

What About Email Deliverability and Reliability?

All three options, when set up correctly with proper authentication (SPF, DKIM, and DMARC, covered in our guide to email deliverability), can achieve strong inbox placement and reliability. The choice between them is generally not a question of which is more reliable, but which feature set and price point genuinely matches your business’s needs.

Frequently Asked Questions

Is Google Workspace or Microsoft 365 better for a small UK business?

Neither is universally better; the right choice depends on which ecosystem your team is more familiar with, and which set of document and collaboration tools you are more likely to use day to day. Both offer broadly comparable core email functionality.

Can I switch from Google Workspace or Microsoft 365 to business email hosting later?

Yes, though this involves migrating existing emails and updating DNS records (specifically MX records) to point to the new email service, alongside informing your team of any changes to how they access email. A managed migration can help make this process smoother. If your website is on Wix, Squarespace or Lovable, you don’t need to move it to make this switch; see our guide to keeping your website builder and moving only your email.

Do I need Google Workspace or Microsoft 365 just to use my own domain for email?

No. Business email hosting also allows you to use a professional email address on your own domain, without needing either of these larger platforms. The domain-based email address itself is independent of which underlying service you choose.

Is business email hosting less secure than Google Workspace or Microsoft 365?

Not inherently. Security depends on the specific provider’s infrastructure and your own configuration (strong passwords, two-factor authentication where available, and correct email authentication setup), rather than which broad category of service you choose.

What is the difference between free email and professional email?

Free services such as Gmail or Outlook.com use their own domain in your address rather than yours, which reads as less established to customers. Paid options, whichever of the three you choose, also give you better support, more storage, and control over authentication records that consumer accounts do not offer.

How much mailbox storage do I actually need?

It depends almost entirely on attachments. A few gigabytes covers most light users. Anyone regularly sending or receiving large files, or who never deletes anything, will want a considerably more generous allowance. Check the per-mailbox figure rather than the headline.

Can I move my existing emails to a new provider?

In most cases, yes. The process involves copying existing mail across, usually over IMAP, and importing it into the new mailboxes. Many providers offer assisted migration, which is worth using if you have a meaningful volume of historic email to keep.
