Most business owners who need to contact Companies House by phone do so because something has gone wrong — a filing is overdue, a company name dispute has arisen, or correspondence from Cardiff has gone unanswered. The good news is that there is a direct route. The less good news is that the process is more limited than most people expect.
This article covers exactly how to contact Companies House by phone, what their contact centre can and cannot help with, and what to do when a phone call is not enough.
How to Contact Companies House by Phone
The main Companies House contact number is 0303 1234 500. This line is open Monday to Friday, 8:30am to 6:00pm, and handles general enquiries about company registrations, filing deadlines, and correspondence. If you are calling from outside the UK, the number is +44 1633 551081.
For Welsh-language enquiries, there is a dedicated line: 029 2038 0065. Companies House also operates a separate service for same-day incorporation and urgent filings, which typically requires you to attend or contact one of their offices directly rather than using the general enquiry line.
It is worth being prepared before you call. Have your company registration number to hand, along with the name of the company and the nature of your query. The contact centre agents can look up filing histories, confirm receipt of documents, and escalate complaints, but they cannot make filing decisions or reverse penalties on the spot.
For context, the average wait time on the general line can vary considerably depending on filing deadlines — January and March tend to be busier periods. If your matter is not urgent, the Companies House webchat and email routes often produce faster written responses that you can reference later.
What You Can and Cannot Resolve by Phone
Understanding the limits of the phone line saves time. From our nine years running a marketing agency — where we helped SMEs manage everything from their company formations to their advertising — we saw a pattern: business owners often called Companies House expecting the phone line to resolve issues it was never designed to handle.
What the phone line can help with includes confirming whether a document has been received, clarifying what a specific notice means, checking the status of a pending incorporation, and directing you to the correct department for a formal objection or complaint. These are genuinely useful functions.
What the phone line cannot do is process a filing on your behalf, waive a late filing penalty, remove information from the public register, or make any binding decision about your company's record. Those outcomes require written submissions — either through the Companies House online portal, by post to their Cardiff or London offices, or via their formal appeals process.
The distinction matters practically. If you contact Companies House by phone to query a late filing penalty, the agent can explain the penalty notice and confirm the amount, but to dispute it you will need to submit a written appeal with supporting documentation. Knowing this before you call means you can prepare both your call and your follow-up in advance.
| Contact Method | Best For | Response Speed | Limitations |
|---|---|---|---|
| Phone (0303 1234 500) | General queries, status checks | Immediate | Cannot process filings or waive penalties |
| Webchat | Quick questions, links to guidance | Same day | Limited to standard queries |
| Email (enquiries@companieshouse.gov.uk) | Detailed questions needing a written record | 5–10 working days | No urgent actions |
| Post (Cardiff or London offices) | Formal appeals, document submissions | Varies | Slowest route |
| Companies House WebFiling portal | Submitting accounts, confirmation statements | Immediate processing | Requires registered email and authentication |
Companies House Phone Number for Specific Queries
Not every query routes through the main line. Companies House operates different contact routes depending on the nature of the enquiry, and knowing which number to use reduces the time you spend being transferred.
For formal complaints about the register or about a specific company's filings, you will typically be directed to the Intelligence and Enforcement team, which does not take direct public calls but accepts referrals through the main contact centre. For disqualified director queries, the Disqualified Directors Register is managed separately and enquiries are best made via the Companies House search service before calling.
If your query relates to company dissolution or striking off — either your own company or a company you have a concern about — the main phone line can direct you, but the substantive process happens through written correspondence. The same applies if you are trying to restore a company to the register, which requires a court order in most cases.
For those dealing with registered office issues or trying to confirm a company's address, the public register search will often answer your question faster than a call. That said, there are situations where a human conversation helps — particularly when the register contains an error and you need to understand the correction process.
If your business needs to contact Companies House by phone about an urgent filing matter, it is also worth checking whether your accountant or company secretary has a faster route. Registered agents and formation agents sometimes have access to priority contact channels that are not publicly listed.
What SMEs Often Get Wrong When Calling Companies House
One observation from working with SMEs over the years: many business owners call Companies House expecting the kind of proactive guidance they would get from an accountant. The contact centre is helpful but it is a public service operating at scale — agents follow scripts, escalate where necessary, and cannot give tailored advice.
The most common mistake is calling without a company registration number. Without it, agents cannot pull up your record and the conversation goes in circles. The second most common mistake is calling about a matter that requires a written decision and expecting a verbal commitment. You will not get one, and any verbal assurance you receive is not binding.
For genuinely complex situations — disputes about company names, objections to a company's registered address being used without consent, or concerns about fraudulent filings — the phone call is the start of a process, not the resolution. Companies House has formal procedures for each of these, and understanding that before you call means you can use the call efficiently to get directed to the right next step.
This matters to SMEs in particular because time spent chasing administrative threads is time not spent on running the business. Companies House is one of several regulatory touchpoints that can absorb attention. Google Ads is another — and unlike Companies House admin, ad spend is something that can be delegated to an AI agent.

Alternatives to Contacting Companies House by Phone in 2026
The phone line remains the fastest route for status queries, but Companies House has expanded its digital services significantly. In 2026, the majority of routine filings and queries can be handled without a phone call at all.
The Companies House WebFiling service handles confirmation statements, annual accounts, and director appointments online. The Find and Update Company Information portal is publicly accessible and provides the same register data that the contact centre uses. For queries about specific documents, the document request service allows you to order copies of filed documents directly.
For SMEs dealing with company secretarial tasks alongside running paid advertising, understanding what Google Ads actually costs is often a more pressing concern than navigating Companies House admin. Both require attention to detail and an understanding of what the system can and cannot do.
If you do need to contact Companies House by phone, the direct route remains 0303 1234 500, Monday to Friday, 8:30am to 6:00pm. For anything that requires a formal written outcome, prepare your submission before you call so you can use the conversation to clarify exactly what to submit and where.
For SMEs managing both administrative compliance and growth, the goal is to spend time where it produces results. Companies House administration has defined processes that, once understood, run efficiently. Advertising management is the area where many SMEs lose time and money to incremental decisions that an AI agent can handle instead. See how Overtime approaches Google Ads management for SMEs who want their ad spend actively managed without the cost of an agency.
If you need to contact Companies House by phone today, call 0303 1234 500 with your company registration number ready. For everything else your business is managing alongside that call — including paid search — the right structure makes the difference between administration consuming your day and processes that run without you.

What can you resolve when you contact Companies House by phone?
You can confirm filing receipt, check company status, query correspondence, and get directed to the correct team for formal matters. You cannot process filings, dispute penalties, or obtain any binding decision over the phone — those require written submissions.
Should I email or call Companies House for a faster response?
For urgent queries where you need an immediate answer, calling is faster. For anything requiring a documented response or where you need a written record, email is preferable. Bear in mind that email responses can take five to ten working days.
Can I contact Companies House by phone about a late filing penalty?
