When Can a New UK Company Start Trading?
A new UK limited company can normally start trading as soon as Companies House has incorporated it and issued its certificate of incorporation. The company does not usually have to wait for its Corporation Tax Unique Taxpayer Reference, business bank account or first confirmation statement.
However, incorporation alone may not be enough for every business. Before carrying out certain activities, the company may need an industry-specific licence, regulatory approval, insurance, VAT registration or an employer PAYE scheme.
The key distinction is between the date the company legally exists and the date it is properly prepared to conduct its particular type of business.
A UK company comes into existence on the incorporation date shown on its certificate of incorporation.
Companies House issues this certificate when it accepts the incorporation application. The certificate confirms important information, including:
Before this date, the company is not a separate legal person. It cannot own property, incur liabilities or enter contracts in its own right.
Once incorporated, the company can generally:
A company should therefore be incorporated before it starts trading in its own name.
In most cases, yes. A private limited company can normally begin trading immediately after its incorporation has been confirmed.
There is no general statutory waiting period after registration. A company does not normally need permission from Companies House to begin ordinary commercial activity.
For example, a newly incorporated consulting company may be able to sign a client contract and begin providing services on the same day it is incorporated.
The company must nevertheless be operationally and legally ready. Depending on its activities, this may mean putting the following arrangements in place before accepting business:
Incorporation creates the company, but it does not automatically grant permission to conduct every regulated activity.
A company does not normally have to wait for its Corporation Tax Unique Taxpayer Reference, or UTR, before it starts trading.
HMRC usually posts the company’s UTR to its registered office after receiving information about the incorporation from Companies House. Delivery times can vary, particularly if the registered office mail must be forwarded to an overseas owner.
The UTR is needed for Corporation Tax administration, but it is not a trading licence. A company can usually begin legitimate, unregulated business activity while waiting for it.
The company should keep complete records from its first transaction so that its accounts and Corporation Tax obligations can be dealt with correctly once its HMRC services are established.
A company generally needs to tell HMRC when it becomes active for Corporation Tax.
HMRC states that a company should provide the relevant information within three months of the start of its first Corporation Tax accounting period. In practical terms, this means the company should deal with its Corporation Tax registration promptly after it starts doing business.
Information that may be required includes:
The director should not confuse this three-month notification period with the Corporation Tax payment or return deadlines. Those deadlines normally occur later, but the company must maintain adequate records from the beginning.
The phrase “starting to trade” is sometimes used loosely. A business owner may think trading begins when the company receives its first customer payment, but HMRC may consider the company active earlier.
Activities that may indicate that a company has become active include:
The precise position depends on the company’s circumstances.
Some preliminary activities may not amount to the beginning of a trade for every tax purpose. For example, developing an initial business plan or conducting early market research may be preparatory rather than active trading. However, once the company begins carrying out meaningful commercial transactions, it should consider whether it is active for Corporation Tax.
Directors should record the company’s intended and actual start dates and retain evidence of its first commercial activities.
A limited company does not necessarily need to have a business bank account before it signs its first contract or incurs its first expense. However, opening a separate account as early as possible is strongly recommended.
A limited company is legally separate from its directors and shareholders. Its money should therefore be kept separate from their personal funds.
Using a dedicated company account helps the business:
If a director pays a company expense personally before the bank account is available, the transaction should be recorded properly—usually through the director’s loan account or as an expense owed to the director.
Customer payments should not routinely be directed into a director’s personal account. This can cause accounting, contractual, compliance and credibility problems.
The company can generally issue an invoice after incorporation even if its business bank account is still being opened.
The invoice should contain the required company and transaction information. Depending on the circumstances, this can include:
The payment terms may allow the customer to pay after the business account becomes available. It is sensible to ensure that the account will be operational before payment is due.
Not every new company needs to register for VAT.
Compulsory registration generally depends on the value of the company’s taxable turnover. A company must normally register if its taxable turnover exceeds the current VAT registration threshold over a rolling 12-month period or if it expects to exceed the threshold within the relevant forward-looking period.
At the time of publication, the UK VAT registration threshold is £90,000, but businesses should check the current figure on GOV.UK because tax thresholds can change.
A company may also need to consider VAT registration where:
Voluntary VAT registration may be available below the threshold. This can allow the company to recover qualifying input VAT, but it also creates administrative and pricing responsibilities.
A company that must be VAT registered should not delay registration simply because it is newly incorporated.
A new company should register as an employer with HMRC before its first payday if PAYE registration is required.
This can apply even where the only employee is a director. Whether PAYE is needed depends on matters such as the director’s salary, benefits, other employment and applicable payroll rules.
Employer registration generally cannot be completed more than two months before the company expects to start paying employees.
The company must also consider:
The company may begin other business activities before hiring, but it should not make its first payroll payment without establishing the required employment and tax arrangements.
Some businesses must obtain a licence, registration or regulatory authorisation before providing particular products or services.
Examples can include companies operating in:
The relevant permission may come from a local authority, a government department or an industry regulator.
A company should not assume that incorporation at Companies House gives it authority to conduct a regulated business. Trading without required approval can lead to penalties, contractual problems, closure or personal consequences for those involved.
Directors should investigate the rules for their specific industry and location before launching.
There is no single insurance policy that every limited company must purchase before it starts trading. The required cover depends on the company’s activities.
Employers’ liability insurance is generally compulsory when the company becomes an employer, subject to limited exceptions. Other forms of insurance may be required by a regulator, professional body, landlord, customer or commercial contract.
Common policies include:
Even where insurance is not legally compulsory, starting work without appropriate cover can expose the company to claims it cannot afford.
The policy should normally be in force before the relevant risk begins—not after the company receives its first claim.
Caution is needed with contracts made before incorporation.
Because the company does not legally exist before its incorporation date, it cannot ordinarily be bound as a party at that time. Under UK company law, a person purporting to contract on behalf of a company that has not yet been formed may become personally liable, unless the agreement provides otherwise.
This can affect:
After incorporation, the company may need to enter into a replacement agreement, or the parties may need to novate the original contract. Incorporation does not automatically transfer every pre-incorporation contract to the new company.
Business owners entering significant contracts before formation should obtain legal advice.
A limited company can often trade under a business name that differs from its registered company name.
For example, a company registered as “Example Ventures Ltd” might use “Example Studio” as its trading name.
However:
Contracts and invoices should make the relationship clear—for example, “Example Studio is a trading name of Example Ventures Ltd.”
The availability of a company name at Companies House does not necessarily mean that the same name is safe to use as a brand or trade mark.
An online business can generally start selling once the company has been incorporated, provided it has completed any applicable legal and operational requirements.
Before accepting orders, an e-commerce company should consider:
The website should clearly identify the limited company behind the business. Hiding the registered company’s identity behind a brand name can create compliance and consumer-trust issues.
A company incorporated in the UK can generally begin trading once incorporated, even if its director or shareholder lives overseas.
However, UK incorporation does not automatically give the owner:
An overseas-managed company may also create tax, registration or permanent-establishment obligations in the country from which it is managed or where it conducts business.
Non-resident owners should consider both UK obligations and the rules of each country in which the company has customers, staff, offices or management.
Yes. A company does not have to start trading immediately.
It can remain dormant until its owners are ready to launch. This may be useful where a company is incorporated to:
A dormant company still has Companies House responsibilities. It will normally need to file:
The company must also maintain required records and keep its registered office details up to date.
Once significant business activity begins, its dormant status may end. Directors should not continue filing dormant accounts after the company has started conducting reportable transactions.
A practical pre-trading checklist includes the following:
Not every item will apply to every company, but addressing them before launch reduces the risk of missed obligations.
Yes. A private limited company can generally start trading on its incorporation date once Companies House has confirmed that it legally exists. Required licences, insurance or regulatory permissions must already be in place.
Yes. The Companies House authentication code is used for online filings. It is not permission to trade.
The code should still be kept secure and obtained promptly so the company can manage its filings.
Usually, yes. The UTR is required for tax administration, but a company does not generally have to wait for it before beginning legitimate business activity.
The company can become entitled to payment, but customer and company money should not routinely pass through a director’s personal account. A dedicated account or other properly established company payment facility should be arranged as soon as possible.
No. Incorporation creates the company, but the business may begin trading days, months or years later.
The actual start date depends on when the company begins meaningful commercial activity.
Possibly, but not always. Purchasing equipment may be preparatory activity, while buying stock for resale or entering commercial contracts may more clearly indicate that the company is active. The tax treatment depends on the facts.
Advertising may indicate that a company has become active, particularly where it forms part of an organised commercial launch. Directors should assess the nature of the activity and obtain accounting advice if the company’s status is uncertain.
Companies House does not normally require a separate filing merely to report that an ordinary private company has started trading. HMRC must be informed when the company becomes active for Corporation Tax, and the company’s accounts must reflect its activities.
The company and those responsible may face penalties, enforcement action, loss of income, contractual disputes or prosecution, depending on the activity. Required authorisation should be obtained before the regulated activity begins.
A new UK limited company can usually start trading as soon as Companies House issues its certificate of incorporation. It does not generally have to wait for its UTR, business bank account or first Companies House filing deadline.
However, the company must obtain any required licences, regulatory approvals, insurance, VAT registration or employer registration before carrying out the activities to which those requirements apply.
Directors should record when the company actually becomes active, keep accounting records from its first transaction and notify HMRC within the applicable Corporation Tax timeframe. Where contracts were made before incorporation, or the company operates in a regulated or overseas market, professional advice may be appropriate.
