Most small business owners discover there are two very different reasons to find and update company information: one is administrative, the other is commercial. Mixing them up costs time and, in the case of paid advertising, money.
This article explains what "find and update company" means across different business contexts — from Companies House filings to Google Ads account settings — and where each type of update has the most direct impact on your bottom line.
How to Find and Update Company Information
When someone searches "find and update company," they are almost always trying to do one of three things: update their own registered company details, find and correct information held about them on a public register, or update company-level settings inside a business account — such as a Google Ads or CRM profile.
To find and update company details on Companies House, you log in at Companies House WebFiling, search for your company by name or number, and submit the relevant form. The most common updates are registered address changes, director appointments, confirmation statements, and annual accounts. These are legal obligations, not optional housekeeping.
The process itself is not technically difficult. The confusion arises because the phrase "find and update company" also appears in business software contexts, where it describes actions inside CRM systems, accounting packages, and advertising accounts. Depending on which system you are dealing with, the stakes — and the consequences of getting it wrong — vary considerably.
Why Company Data Accuracy Affects More Than Just Compliance
Registered company information feeds into a surprising number of downstream systems. Credit reference agencies pull from Companies House. Suppliers and prospective clients look there before signing contracts. If your trading address differs from your registered address, that alone can create friction during due diligence. After nine years running a marketing agency, we saw this cause problems more often than clients expected, particularly during onboarding with media buying accounts that required business verification.
Google Ads, for instance, requires accurate business information to verify your advertiser identity. Discrepancies between what Google holds and what appears on Companies House can trigger verification holds, pausing campaigns at the worst possible moment. The fix is straightforward — you need to find and update company details in both places — but most SMEs only realise this when ads stop serving.
Accuracy in business registers also affects local search visibility. Google's Business Profile pulls signals from multiple sources, and inconsistent information across directories and Companies House creates conflicting signals that suppress rankings. Keeping your registered and trading information aligned is not just an administrative task; it is part of your commercial infrastructure.

Companies House: The Authoritative Starting Point
What the Public Register Actually Contains
Companies House holds incorporation documents, confirmation statements, accounts, officer information, and significant persons of control (PSC) data. All of this is publicly accessible. When you need to find and update company details for a UK limited company, Companies House is the definitive source — not HMRC, not credit agencies, not your own website.
For reference, here is what each major record type requires and how often it needs updating:
| Record Type | Trigger for Update | Deadline | Method |
|---|---|---|---|
| Registered Address | Whenever you move | Within 14 days | WebFiling or paper |
| Director Details | Appointment or resignation | Within 14 days | WebFiling or paper |
| Confirmation Statement | Annually | Within 14 days of review date | WebFiling |
| Annual Accounts | Each financial year | 9 months after year end | WebFiling or accountant |
| PSC Information | Change in control | Within 14 days | WebFiling |
What Happens If You Don't Update
Failure to file on time results in automatic financial penalties starting at £150 for accounts and rising steeply. Directors can be struck off. The company can be dissolved. None of this is obscure — it is covered in your statutory obligations — but the volume of dissolved companies on the register suggests these deadlines are frequently missed by small businesses without a finance function keeping track.

Find and Update Company Settings Inside Google Ads
There is a separate but equally important version of "find and update company" that lives entirely inside your Google Ads account. Your business name, billing address, time zone, and currency are all set at account level, and errors here create cascading problems across campaign reporting, invoice reconciliation, and advertiser verification.
To access these settings, log into your Google Ads account, navigate to Admin, then Business Details. This is where Google holds the name and address associated with your advertiser account. If this does not match your Companies House record, you may fail Google's advertiser verification process — introduced with increasing strictness over recent years — and your ads may be paused pending identity confirmation.
The practical implication is that to find and update company settings inside Google Ads, you need your Companies House registration number, your registered business name exactly as it appears on the register, and a matching billing address. Google cross-references these during verification. Using a trading name that differs from your registered name without providing proper documentation is a common reason verification fails.

Where Manual Updates Become a Problem for SME Advertisers
The Hidden Cost of Infrequent Account Reviews
For most SMEs running Google Ads, the administrative task of keeping company details current is not the primary problem. The bigger issue is that account-level settings — budgets, bid strategies, keyword lists, and audience exclusions — also require regular updating, and very few small businesses have the time or expertise to do this consistently.
In our agency experience, accounts left without active management for more than two or three weeks would typically drift: spend would concentrate on the worst-performing ad groups, daily budgets would be exhausted before peak hours, and broad match keywords would consume budget on irrelevant queries. None of this is inevitable, but it requires someone to be watching, analysing, and acting regularly.
This is a different kind of "find and update company" problem — finding where your account is underperforming and updating the settings that govern it. The information is available in Google Ads reporting; acting on it consistently is the challenge.
What Oversight Actually Requires
Proper Google Ads oversight in 2026 means checking search term reports at least weekly, adjusting bids in response to conversion data, pausing ads with deteriorating quality scores, and reallocating budget from underperforming campaigns to those showing return. For a business owner managing operations, sales, and everything else, this either does not happen or happens infrequently enough to make campaigns inefficient.
For more on what effective Google Ads management involves at a granular level, the PPC Ad Management Services guide outlines what consistent oversight actually looks like in practice.
Using an AI Agent to Keep Google Ads Updated
Overtime is an AI agent built specifically for SMEs that handles the ongoing task of monitoring and updating Google Ads accounts. It logs into your account directly, reviews performance data, adjusts bids, pauses underperforming keywords and ads, reallocates budget based on what is working, and sends you a plain-English summary of what it did and why.
This matters in the context of this article because the goal of "find and update company" settings — whether in Companies House or in Google Ads — is ultimately the same: making sure the information that governs your business operations is accurate and current. For registered company details, that is a legal requirement you handle once per year. For advertising account settings, it is a commercial requirement that ideally happens every day.
The distinction is worth holding onto: keeping your Companies House record accurate is about compliance. Keeping your Google Ads account accurate is about not wasting money.

Frequently Asked Questions
How do I find and update company information on Companies House?
Visit the Companies House WebFiling service, search for your company by name or registration number, and log in to submit the relevant form. Updates to registered address, director details, and confirmation statements are the most common filings and must typically be made within 14 days of any change.
What happens if my Google Ads business details don't match Companies House?
Google may flag your account during advertiser verification and pause your campaigns until you provide matching documentation. The verification process cross-references your business name and address, so discrepancies — even minor ones like using a trading name instead of your registered name — can cause holds.
How often should I update company settings in Google Ads?
Business details such as name and address should reflect your current registered information at all times. Campaign settings — bids, budgets, keywords, and audience exclusions — should ideally be reviewed and updated weekly based on performance data, though most SMEs without dedicated resource manage this far less frequently.
Why does keeping company information accurate matter for advertising?
Inconsistent business information across registers, directories, and advertising accounts creates conflicting signals that affect both advertiser verification and local search visibility. Accurate, aligned information across Companies House, Google Business Profile, and your ad accounts removes unnecessary friction from both compliance and commercial activity.
Should I use an AI agent to manage my Google Ads account updates?
For SMEs without a dedicated PPC resource, an AI agent that monitors and updates account settings daily is a practical alternative to either doing it manually or paying agency management fees. It is most effective when business details are already accurate at account level, giving the agent a clean foundation to optimise performance from.
