Frequently Asked Questions
Do your Office keys work in my country?
Yes. Our Office licences are global, multi-language keys — you select your preferred language during installation and the key activates through Microsoft from anywhere in the world.
Is Microsoft Office a one-time purchase here?
Yes — all Office licenses sold by LicenceHouse (except Office 365 accounts) are perpetual. You pay once and use the software indefinitely. There are no renewal fees or subscriptions.
Can I use my Office key on a new PC if I replace my old one?
Retail licenses are transferable — deactivate from the old machine and activate on a new one. OEM/LTSC licenses are tied to the first device. Check each product listing for the license type.
What is the difference between Office 2021 and Office 365?
Office 2021 is a one-time purchase with the feature set fixed at release — no future feature updates. Office 365 (Microsoft 365) is subscription-based, always running the latest version. Our Office 365 accounts provide lifetime access at a one-off cost.
