Every year in the UK, hundreds of thousands of company names quietly drop off the register. Some belonged to failed start-ups. Others to profitable businesses that simply restructured or closed. In the 2023–24 financial year alone, over 500,000 companies were dissolved or struck off the Companies House register, according to the UK government’s official statistics.
That number matters because every one of those dissolutions leaves behind a name. Sometimes it is a name with search traffic, backlinks, reputation, or brand recognition. Sometimes it is just a name that fits perfectly with a new business idea. Founders, agencies, and investors regularly want to use a dissolved company name when they spot one of these opportunities, but very few understand what the law actually allows.
The problem is that a dissolved company name does not simply vanish when the business is struck off. UK company law treats registered names, trademarks, and restoration rights as separate things. You might be able to use a dissolved company name on Companies House, yet still be blocked by trademark law or by a former owner restoring the company months later.
This guide cuts through that confusion so you know exactly where you stand before you commit to a name.
What Does “Dissolved” Actually Mean?
When a UK company is dissolved, it is removed from the Companies House register and legally stops existing. It can no longer trade, hold assets or have directors. This usually happens after a voluntary strike-off or when Companies House closes a business for failing to file its paperwork.
What often gets missed is that the company’s record does not disappear. Its name, filings and director history stay visible on Companies House for years. More importantly, some rights can survive dissolution. Trademarks may still be active, and former owners or creditors can apply to restore the company. That means a dissolved company is gone, but its name is not always as free to use as it looks.
Is a Dissolved Company Name Available for Reuse?
In the UK, Companies House will usually release a company name once a business has been formally dissolved. That is why, in many cases, you can apply to register the same name again just weeks after the old company is struck off. On the surface, this makes it look like you are free to use a dissolved company name without any restrictions.
The risk sits outside Companies House. Even if the name is technically available on the register, it may still be protected by a live trademark, owned by the former company or by someone who bought the brand. If you go ahead and use a dissolved company name that is still covered by trademark rights, the new company can be forced to change its name, hand over domains, or stop trading under that brand. That is why checking Companies House alone is never enough when you are reusing a dissolved name.
When You Cannot Reuse a Dissolved Name
Even if Companies House shows a dissolved name as available, that does not mean it is safe to take. Several legal and regulatory blocks can still apply.
Names Protected by Trademarks
A dissolved company’s trademark does not die with the business. If the brand was registered with the UK Intellectual Property Office, those rights can stay active for years. Using the same name for similar products or services can trigger infringement, even if the company no longer exists on the register.
Sensitive and Regulated Words
Some words are restricted by law, including terms like “bank”, “royal”, “insurance” and “charity”. If a dissolved company had permission to use one of these, that approval does not automatically transfer to a new company. Your application can be rejected even if the name looks free.
Names Linked to Fraud or Harm
Companies House can block or remove names connected to scams, misleading trading or serious misconduct. If a dissolved business caused public harm, the registrar can prevent anyone else from using that name again.
What Happens If the Old Company Is Restored?
If a dissolved company is restored, it legally regains its original name. Any new business that chose to use a dissolved company name during that gap can be forced by Companies House to change it and rebrand.
Restoration Brings the Name Back
If a former director, shareholder or creditor restores the dissolved company through court or administrative restoration, it is treated as if it never left the register. The company gets its original name back.
The New Company Must Change
If you formed a new company using that same name in the meantime, Companies House can force you to change it. You might also have to rebrand your website, contracts and marketing, which is expensive and disruptive.
How to Check If a Dissolved Name Is Really Available
Before you commit to any name that belonged to a dissolved company, you need to run more than one check. Skipping this step is how most rebranding disasters happen.
Check Companies House
Search the full name on Companies House and look at its status. Make sure the company is genuinely marked as dissolved and not just dormant or in liquidation. Also check how recently it was struck off, because very recent dissolutions carry a higher restoration risk.
Search the UK trademark register
Use the UK Intellectual Property Office database to see if the name is registered as a trademark in the classes you plan to trade in. If there is an active or pending mark that covers your products or services, the name is not safe to use, even if the company itself no longer exists.
Look beyond the registers
Check who owns the domain name, whether the brand still appears on marketplaces, and whether customers still associate the name with the old business. A name can be legally available and still be a reputational problem if people link it to poor service or past disputes.
Should You Reuse a Dissolved Company Name?
Reusing a brand that already exists on the internet can be tempting, especially when you want quicker visibility. For some founders, the chance to use a dissolved company name with existing search presence, backlinks or industry recognition feels like a shortcut to growth.
When it can work in your favour
If the old business built a good reputation and still attracts organic traffic, being able to use a dissolved company name can give you an immediate head start. This is common in sectors like digital services, ecommerce and local trades, where people often search by brand rather than by company number.
When it becomes a liability
If the previous company closed after poor service, disputes or bad reviews, that history will still be attached to the name online. You might inherit negative press, complaints and low trust before you have even made your first sale.
Making the right call
The legal side matters, but so does perception. A name that looks attractive on Companies House can be far harder to rebuild in the real world if it already carries the weight of a failed business.
How to Safely Register a Reused Company Name
If you are planning to use a dissolved company name, the steps you take before and after registration are critical.
Run all checks first
Confirm the company is marked as dissolved on Companies House, then search the UK Intellectual Property Office for active or pending trademarks. Also review domain ownership and any signs that the brand is still being used. Even when you want to use a dissolved company name, a live trademark or active trading presence can block you.
Register the company quickly
Once the name shows as available, file your incorporation without delay. Released names are often picked up fast, especially those with SEO or brand value.
Protect the brand properly
After incorporation, apply for your own trademark. This is what turns a registered name into a legally protected brand.
Plan for restoration risk
Recently dissolved companies can still be restored. Many founders tweak the name slightly to reduce the chance of being forced to change it later.
Conclusion
In the UK, it is often possible to use a dissolved company name, but that does not mean it is risk free. Companies House may release the name, yet trademark rights, restoration claims and online reputation can all sit quietly in the background waiting to cause problems. A name that looks available on a register can still belong to someone in practice.
If you do the right checks, understand the legal landscape and protect the brand properly, reusing a dissolved name can work. If you skip those steps, it can lead to forced rebrands, lost domains and costly disputes. A few hours of due diligence before you file can save months of trouble after you launch.
FAQs
1. Can I legally use a dissolved company name in the UK?
Yes, in many cases you can, as long as Companies House shows the name as available. However, you must also check for active trademarks and restoration risks before you use it.
2. How long after dissolution does a name become available?
Companies House often releases a name within days of dissolution being published in the Gazette. There is no fixed waiting period, but the old company can still be restored for several years.
3. What happens if the dissolved company is restored after I register the name?
If the original company is restored, it regains its legal name. Your company may be forced to change its registered name, even if you have already been trading under it.
4. Do I need to check trademarks if the company no longer exists?
Yes. Trademarks can survive dissolution and can also be sold to third parties. A live trademark can stop you using the name, even if the company is gone.
5. Is it safer to slightly change a dissolved company name instead of using it exactly?
Often, yes. Adding a distinctive word or variation can reduce the risk of restoration conflicts and trademark disputes while still allowing you to benefit from any brand recognition.
