Office 365 Lifetime (5 Devices) vs 5 Separate Office 2024 Licences — Which Saves UK Buyers More in 2025?

📅 2026-03-28  ·  ✍️ Softkeys Tech Team  ·  🏷️ Office

You have got a household with multiple computers. Or a small team. Or you are just someone who works across a desktop and a laptop and maybe a tablet. Either way, you need Microsoft Office on more than one device — and you are staring at two very different options.

Option A: One Office 365 Pro Plus lifetime licence that covers 5 devices for £19.99. Option B: Buying 5 separate Office 2024 Pro Plus licences at £29.99 each. The price gap is enormous — but is the cheaper option actually better? Let us break this down properly.

The Price Showdown — Raw Numbers

Before we get into features, let us just look at what each approach costs for covering 5 devices:

Approach Unit Cost Total for 5 Devices Cost Per Device
Office 365 Lifetime (5 Devices) £19.99 £19.99 £4.00
5× Office 2024 Pro Plus £29.99 each £149.95 £29.99
Microsoft 365 Family (official) £79.99/year £399.95 (5 years) £80/year

The numbers speak loudly. The Office 365 lifetime licence is 7.5 times cheaper than buying individual Office 2024 licences, and roughly 20 times cheaper over five years than Microsoft's own subscription. But cost alone does not tell the whole story.

What You Get With Each Option — Feature Comparison

Both options give you the core Microsoft Office desktop applications. But there are meaningful differences in how they work:

Feature Office 365 Lifetime (5 Devices) Office 2024 Pro Plus (Per Device)
Word, Excel, PowerPoint
Outlook
OneNote
Access (Windows only)
Publisher (Windows only)
Devices covered Up to 5 1 per licence
PC and Mac support ✅ Both ✅ Both
Licence type Account-based Device-based
Transferable to new device ✅ (deactivate old, activate new) ⚠️ Limited (tied to device)
Recurring payments ❌ None ❌ None
OneDrive cloud storage Varies ❌ Not included
Automatic updates ✅ Ongoing ⚠️ Security only (no feature updates)

Scenario 1 — UK Family With Multiple Computers

This is the most common situation. You have a family of two adults and perhaps a teenager or university student. There are three to five devices in the house — a mix of laptops and maybe a desktop. Everyone needs Word, Excel, and PowerPoint.

Winner: Office 365 Lifetime (5 Devices)

At £19.99 total, this is the single best value proposition in UK software right now. One purchase, five installations, done. Each family member gets the full Office suite on their machine. If someone gets a new laptop for Christmas, you deactivate the old device and install on the new one.

The only scenario where individual Office 2024 licences make sense for a family is if you specifically need each device to have its own independent licence that is not linked to a shared account. For most families, this is unnecessary.

Scenario 2 — UK Small Business With 5 Employees

This is where it gets more nuanced. A small business with 5 employees might seem like the perfect use case for the 5-device licence — but there is an important consideration.

The Office 365 lifetime licence is tied to one Microsoft account. In a business context, this means all five devices share a single account. For some small businesses (a family business, a husband-and-wife consultancy, a sole trader with multiple machines), this is perfectly fine.

But if you need each employee to have their own Microsoft account with their own OneDrive, their own Outlook mailbox, and their own login credentials, individual licences or a Microsoft 365 Business plan is more appropriate.

The practical middle ground: Many UK small businesses use individual Office 2024 licences for the desktop apps and separate email hosting (Google Workspace or Microsoft 365 Exchange Online at £3.30/month per user) for email. This hybrid approach gives independence per employee while avoiding the £99.99/year per-user cost of full Microsoft 365 Business.

Scenario 3 — Freelancer or Remote Worker With Multiple Devices

You work on a desktop at home and a laptop on the go. Maybe you also have a tablet for reading documents. You are one person, but you need Office on multiple devices.

Winner: Office 365 Lifetime (5 Devices), overwhelmingly

For a single user with multiple devices, there is absolutely no reason to buy separate licences. The 365 lifetime licence covers all your machines under one account for £19.99. Buying even two Office 2024 licences would cost £59.98 — three times more.

Scenario 4 — IT Manager Deploying Across Company Machines

If you manage IT for a UK company with more than 5 users, neither of these options is your primary solution. You would typically use volume licensing or Microsoft 365 Business plans. However, for small offices or departments with exactly 5 machines, the Office 365 lifetime licence can serve as a remarkably cost-effective stopgap.

The Update Question — Does It Actually Matter?

One of the most frequently asked questions from UK buyers is about updates. Office 2024 Pro Plus receives security updates but not feature updates — its feature set is frozen at the 2024 release. Office 365 (including the lifetime variant) receives ongoing feature updates as Microsoft releases them.

In practice, how much does this matter? For most users, honestly, very little. The core functionality of Word, Excel, and PowerPoint has been largely stable for years. The new features Microsoft adds are typically AI-related (Copilot integrations) or minor UI tweaks. If you are writing documents, building spreadsheets, and creating presentations, both versions do the job identically.

Where updates matter more is in security. Both options receive security patches, so you are covered either way. The difference is purely in new features — and for most UK remote workers and small businesses, the features in Office 2024 are more than sufficient for years to come.

Transferability — The Hidden Advantage of 365

Here is something many UK buyers overlook: what happens when you replace a computer?

With Office 2024 Pro Plus (device-based licence), transferring to a new machine can be complicated. The licence is tied to the hardware it was originally installed on. While Microsoft's terms do allow transfer in some cases, it is not always straightforward.

With Office 365 lifetime (account-based licence), you simply sign into your Microsoft account on the new device, and Office installs. You can deactivate old devices and activate new ones freely, up to 5 active at any time. Over a 5-10 year period, this flexibility is significant — most people replace at least one computer in that time.

What About Mac Users?

Both options fully support macOS. If you have a mixed household with Windows PCs and Macs, the Office 365 lifetime licence is particularly attractive because it covers all platforms under one licence. With Office 2024, you would need to buy the correct version for each platform — and confirm the key works for Mac before purchase.

Our Verdict — Which Should UK Buyers Choose?

Let us make this simple:

If You Are... Choose This Why
One person, one device Office 2024 Pro Plus (£29.99) Full suite, one-time payment, latest version
One person, 2-5 devices Office 365 Lifetime (£19.99) Covers all devices for less than one Office 2024 licence
Family with multiple PCs/Macs Office 365 Lifetime (£19.99) Unbeatable value at £4 per device
Small team, shared account OK Office 365 Lifetime (£19.99) Cheapest way to equip 5 machines
Business needing separate accounts 5× Office 2024 Pro Plus (£149.95) Independent licences per employee

For the vast majority of UK buyers, the Office 365 lifetime licence at £19.99 for 5 devices is the clear winner. It is cheaper, more flexible, and covers more devices than any other option on the market.

The maths do not lie: £19.99 for 5 devices versus £149.95 for 5 individual licences. Unless you specifically need independent accounts per user, the choice is obvious.

Frequently Asked Questions

Can I mix PC and Mac devices on one Office 365 lifetime licence?
Yes. The Office 365 Pro Plus lifetime licence from Softkeys.uk covers up to 5 devices across both PC and Mac. You can install it on any combination — three Windows PCs and two Macs, or five Macs, or any other mix. There is no platform restriction.
What happens if I replace one of my 5 devices — can I transfer the licence?
Yes. With the Office 365 lifetime licence, you can deactivate one device and activate a new one through your Microsoft account. This flexibility is one of the key advantages over Office 2024 individual licences, which are typically tied to a single machine.
Do both options include Outlook for email?
Yes. Both Office 2024 Pro Plus and Office 365 Pro Plus lifetime include Outlook, Word, Excel, PowerPoint, and the full desktop suite. The functionality is virtually identical — the difference is in how many devices you can install on and how you pay.
Is the Office 365 lifetime licence really lifetime, or does it expire?
The lifetime licence from Softkeys.uk is a one-time payment with no expiry date and no recurring charges. It is not a subscription. Softkeys.uk backs this with a lifetime warranty — if anything goes wrong, they replace your key at no extra cost.
Which option is better for a UK small business with 5 employees?
For 5 employees who each need Office on one device, buying 5 individual Office 2024 licences (5 × £29.99 = £149.95) works but costs more. The Office 365 lifetime licence at £19.99 for 5 devices is dramatically cheaper — but each device would share the same account. For businesses needing separate accounts per employee, individual licences or Microsoft 365 Business plans are more appropriate.
Are these licences legal to buy in the UK?
Yes. Software licence resale is legal in the UK under principles established by the UsedSoft v Oracle ruling. The Consumer Rights Act 2015 also protects UK buyers of digital products. Softkeys.uk is a UK-registered business with over 8,174 verified reviews and a 4.28-star rating.
