A trademark isn't a one-off purchase. Register a trademark in UK and you get ten years of protection, not protection forever, and plenty of businesses lose their mark simply because nobody diarised the renewal date. Maintaining a trademark properly takes almost no effort compared to getting it registered in the first place, but skip the basics and you can lose rights you spent real money securing.
When Renewal Falls Due
UK trademarks last ten years from the filing date, then need renewing indefinitely in further ten-year blocks. There's no cap on how many times you can renew, so a mark registered in 1995 can still be protected today, provided every renewal was filed on time.
The UK Intellectual Property Office sends a reminder around six months before expiry, but don't rely on that email arriving or landing in the right inbox. Businesses change registered addresses, staff leave, email accounts get closed. Put the renewal date in your own calendar the day your trademark gets registered, not when you eventually remember it exists.
You can renew up to six months before the expiry date, and there's a grace period of six months after expiry where you can still renew, though you'll pay a late fee on top of the standard cost. Miss that grace period entirely and the mark is removed from the register. At that point, someone else can register the same name for the same goods and services, and you'll have no grounds to stop them beyond an expensive passing off claim.
What Renewal Actually Costs
Renewing a single class costs £200 through gov.uk, with £50 for each additional class. That's more than the original registration fee, which surprises people who assume renewal should be cheaper than the initial filing. It isn't, and budgeting for it as a recurring cost, the same way you'd budget for your annual Companies House confirmation statement, avoids the shock.
If you registered several classes originally but no longer sell products in one of them, renewal is the moment to drop it. There's no obligation to renew every class you originally filed. Cutting classes you don't use any more saves money and, more importantly, clears the way for someone else's legitimate use of that name in a market you've abandoned, rather than sitting on rights you're not using.
Proving You're Using the Mark
Registration alone doesn't guarantee permanent protection. If you don't use your trademark for five consecutive years, it becomes vulnerable to a "non-use" revocation application from a competitor. This trips up businesses that registered a name defensively, perhaps during UK company incorporation, then never actually launched the product or shelved the brand after a rebrand.
Keep basic evidence of use as you go: dated invoices, packaging, website screenshots with timestamps, marketing material. You don't need a filing cabinet of proof, just enough that if someone challenges the mark, you can show genuine commercial use within the relevant five-year window. Businesses that skip this and get challenged years later often struggle to produce anything convincing, because nobody thought to keep records at the time.
Keeping Your Details Current
The IPO needs your correct address to send renewal reminders and any legal notices about your mark. If your business has moved, changed its registered office, or switched company structure since incorporation, update your details with the IPO separately. Companies House and the IPO are different registers, and updating one doesn't automatically update the other.
This matters more than it sounds. A missed renewal notice because it went to an old office address is still a missed renewal. The consequence is the same as if you'd simply forgotten.
Watching for Infringement
Maintaining a trademark isn't only about paperwork. It means keeping an eye on whether anyone else is using something too close to your mark. The IPO doesn't police this for you, it registers your rights but leaves enforcement to you as the owner.
Set up a periodic check of new trademark applications in your sector, either by reviewing the Trade Marks Journal yourself or by paying a watching service to flag anything similar. Catching a conflicting application during its two-month opposition window is far cheaper and simpler than trying to challenge a mark after it's already registered and in use.
Expanding Protection as You Grow
If your business starts selling into new categories, your original trademark classes might not cover them. A company that registered a food brand under class 29 and later launches a range of kitchenware needs a fresh filing under class 21, not an amendment to the old one. You can't add classes to an existing registration after the fact, you file a new application.
The same goes for international growth. A UK trademark only protects you in the UK. If you start trading into the EU or the US, you'll need separate applications or an international filing through the Madrid Protocol, which lets you extend protection to multiple countries from a single base application.
Treat your trademark the way you treat your annual accounts or your confirmation statement: a routine task with a fixed deadline, not something to think about only when a problem forces your hand.
