Microsoft Office product keys from £9.99 – compare Microsoft Office keys for Windows PCs across Office 2024, Office 2021 and Office 2019, with one-time purchase licences, fast digital delivery and UK-based support.
Shop Microsoft Office by version:
Office 2024, Office 2021 and Office 2019 are all available for compatible Windows PCs, but they are at very different stages of Microsoft's support lifecycle. For most new purchases, Office 2024 should normally be considered first unless you have a specific reason to use an older version.
Office 2024 is the current perpetual Office generation and has the longest remaining Microsoft support period of the versions listed here, extending into October 2029. It is normally the best starting point for a new purchase where compatibility with an older Office generation is not required. Compare Microsoft Office 2024 editions .
Office 2021 may still suit customers who have a specific compatibility requirement or need to remain with the 2021 generation for an existing setup. However, Microsoft support for Office 2021 ends in October 2026, after which normal security updates, bug fixes and technical support will no longer be provided.
Office 2019 is an older Office generation that reached the end of Microsoft's support lifecycle in October 2025. It remains available for customers with a particular Office 2019 requirement, but it should not normally be the first choice for a new long-term installation.
Buying Microsoft Office in 2026? For most customers choosing between these generations today, Office 2024 provides the longest remaining period of Microsoft support. Choose Office 2021 or Office 2019 where an older version is specifically required for compatibility or an existing setup.
The Microsoft Office products listed on this page are one-time purchase licences for the version and number of PCs or users stated on the individual product page. They do not require an ongoing Microsoft 365 subscription.
Microsoft 365 is a subscription service and can include benefits such as cloud storage, use across multiple devices, ongoing feature updates and other connected services depending on the plan. A one-time Office licence can be a better fit if you mainly want installed desktop Office applications on a compatible Windows PC without a recurring subscription. Always check the individual product description for the included applications, permitted devices and activation requirements.
These guides answer some of the most common questions customers have before choosing a Microsoft Office licence.
