Office 2024 Pro Plus vs Office 2021 Pro Plus: Is the Upgrade Actually Worth It for UK Users in 2025?
Microsoft released Office 2024 in late 2024, and UK users have been asking the same question ever since: is it worth upgrading from Office 2021, or is Microsoft just reshuffling the same deck chairs?
Having tested both versions extensively, the answer is more nuanced than Microsoft's marketing would suggest. Here's an honest, feature-by-feature breakdown designed specifically for UK users deciding where to spend their money in 2025.

The Headline Differences Between Office 2024 and Office 2021
Let's start with what actually changed. Office 2024 Pro Plus isn't a revolutionary overhaul — it's an iterative improvement. But several of those improvements matter significantly depending on how you use Office.
| Feature | Office 2021 Pro Plus | Office 2024 Pro Plus |
|---|---|---|
| Dynamic Arrays in Excel | Limited support | Full native support |
| XLOOKUP Function | Available | Enhanced with new parameters |
| User Interface | Classic ribbon | Refreshed visual design, rounded corners |
| Accessibility | Basic tools | Enhanced checker, improved screen reader support |
| PowerPoint Recording | Basic recording | Cameo + improved recording studio |
| Outlook | Classic Outlook | Option for New Outlook UI |
| Support Lifecycle | Ends October 2026 | Ends October 2029 |
| Minimum OS | Windows 10 | Windows 10 |
| Price at Softkeys.uk | Discontinued | £29.99 |
Excel: Where the Real Differences Live
If you use Excel for anything beyond basic spreadsheets, Office 2024 is a meaningful upgrade. The full native support for dynamic arrays changes how formulas work — functions like SORT, FILTER, UNIQUE, and SEQUENCE now spill results automatically across multiple cells without requiring Ctrl+Shift+Enter.
For UK accountants, analysts, and finance professionals, this alone justifies the upgrade. Dynamic arrays make complex data manipulation dramatically faster. What previously required helper columns and nested formulas can now be accomplished with single, elegant expressions.
Office 2021 introduced some of these features, but Office 2024 makes them first-class citizens of the Excel experience. The formula bar is more intelligent, autocomplete suggestions are more accurate, and the performance handling large datasets has improved noticeably.
New Excel functions in Office 2024 include IMAGE (embed images in cells), TEXTSPLIT (parse text into rows and columns), and GROUPBY/PIVOTBY for creating dynamic summary tables without traditional pivot tables. If you work with data regularly, these aren't gimmicks — they're genuine productivity gains.
Word: Polished but Not Transformed
Word in Office 2024 is a refinement rather than a reinvention. The visual design is cleaner, with subtle updates to spacing, typography, and the ribbon interface. Co-authoring improvements make real-time collaboration smoother, though this matters more for Microsoft 365 users with cloud-connected documents.
The accessibility checker has been significantly improved — relevant for UK businesses required to produce accessible documents under the Equality Act 2010. The improved screen reader support and automatic alt-text suggestions for images make compliance easier.
For most UK home users, Word in Office 2024 will feel familiar. The improvements are real but incremental. If Word in Office 2021 does everything you need, you won't find a compelling reason to upgrade based on Word alone.
PowerPoint: The Biggest Visual Leap
PowerPoint received perhaps the most noticeable improvements. The Cameo feature lets you embed a live camera feed directly into your slides — useful for UK professionals delivering hybrid presentations where remote and in-person audiences need to see the speaker.
The recording studio has been overhauled, making it significantly easier to record narrated presentations for training materials, client proposals, or educational content. Given the UK's continued embrace of remote and hybrid working, this is genuinely practical.
Design suggestions have improved, offering more professional templates and layout options. The morph transition has been refined for smoother animations between slides. For anyone regularly creating presentations — sales teams, educators, consultants — Office 2024's PowerPoint is a clear step forward.
Outlook: The Controversial Update
Outlook in Office 2024 offers the option to switch to the 'New Outlook' interface — a web-based design that Microsoft is pushing as the future of the email client. Opinions are sharply divided.
The new interface is cleaner and more modern, but it removes some features that power users rely on. Custom form support, certain add-in compatibilities, and offline data file management work differently (or not at all) in the new version.
The good news: Office 2024 still includes classic Outlook. You can try the new interface and switch back if it doesn't suit you. For UK businesses with established Outlook workflows, sticking with the classic version while it remains available is the pragmatic choice.
Access and Publisher: Still Included, Still Niche
Both Access (database management) and Publisher (desktop publishing) remain part of the Pro Plus package. Neither received dramatic updates, but both continue to serve their core user bases effectively.
For UK small businesses using Access databases for customer records, inventory, or invoicing, Office 2024 maintains full backward compatibility with existing databases. Publisher continues to handle newsletters, marketing materials, and business cards competently.
These applications are why the Pro Plus edition exists. If you need Access or Publisher, you need Pro Plus — and at £29.99 from Softkeys.uk, it's extraordinary value compared to any alternative that includes database and desktop publishing capabilities.
Performance and System Requirements
Office 2024 is noticeably faster on modern hardware. Application launch times are shorter, large files open more quickly, and memory management has improved. The improvements are most apparent on systems with SSDs and 8GB+ RAM.
System requirements remain reasonable. Both Office 2021 and Office 2024 require Windows 10 or later, so there's no compatibility barrier for most UK users. The installer size is marginally larger for Office 2024, but the difference is negligible on modern broadband connections.
Support Lifecycle: The Hidden Factor
This is where the upgrade argument becomes strongest. Office 2021's mainstream support ends in October 2026 — just over a year from now. Extended support provides security updates for a few more years after that, but no new features or non-security fixes.
Office 2024's support runs until October 2029. That's four additional years of security patches and support. For UK businesses that need to demonstrate compliance with data protection regulations (including UK GDPR), running supported software isn't optional — it's a requirement.
Even for home users, running unsupported Office software means vulnerability to exploits that Microsoft won't patch. At £29.99 for four extra years of support, the cost-per-year calculation makes Office 2024 the obvious choice.
The Cost Calculation for UK Buyers
Here's where the decision becomes simple. At Softkeys.uk, Office 2024 Pro Plus costs £29.99. That's a one-time purchase with a lifetime warranty and instant delivery.
Compare this to Microsoft's direct pricing of £349.99 for Office 2024 Home & Business (which doesn't even include Access or Publisher). Or compare it to a Microsoft 365 subscription at £59.99 per year.
Over a five-year period:
- Microsoft 365 subscription: £299.95
- Microsoft direct purchase: £349.99
- Office 2024 Pro Plus from Softkeys.uk: £29.99
The savings are not marginal — they're transformative. A UK family buying licences for two computers saves over £600 compared to Microsoft's subscription model.

The Verdict: Should You Upgrade?
Upgrade if: You use Excel extensively, need longer support lifecycle, want improved PowerPoint features, or are buying fresh for a new computer. At £29.99, the cost barrier is essentially zero.
Wait if: Office 2021 does everything you need, you don't use Excel's advanced features, and you're comfortable running software approaching end-of-support. But plan your upgrade before October 2026.
Best value play: If you're buying any Office product today, there's no reason to choose 2021 over 2024. The price difference at reseller level is minimal, and you get four extra years of support plus meaningful feature improvements.
For UK buyers, Softkeys.uk offers Office 2024 Pro Plus at £29.99 with instant delivery, lifetime warranty, and the backing of 8,174 verified customer reviews. That's not just a good deal — it's the smartest way to buy Microsoft Office in 2025.
