What 'ownership' means for a website like OLBG

Operator vs brand name

When a site like OLBG is described as "owned by" a company, the practical meaning is that the named company is legally responsible for operating the service and running promotions under that brand.

In the U.K., the statutory register maintained by Companies House is the authoritative place to see which legal entity is behind a traded name; on-site marketing names do not replace statutory entries.

Marketing content and a consumer-facing brand can describe a site in plain language, but the legal record is the company registration and related filings that show who is the operator or promoter for regulatory and contractual purposes.

OLBG’s site footer and competition terms name Invendium Ltd as the promoter, which is consistent with the company-level entries you will find on the Companies House pages.

How to verify OLBG ownership yourself: step-by-step

Check Companies House overview

Open Companies House and search for Invendium Ltd or paste the company number 04490764 directly into the search box to reach the official overview page.

Who owns OLBG and how can I confirm it?

OLBG is operated by Invendium Ltd according to Companies House and on-site disclosures; confirm by viewing the Companies House company overview, PSC, officers, and the OLBG prizes terms, saving access dates as you go.

Check persons with significant control and officers

From the overview, open the persons with significant control (PSC) and officers tabs to see the names and roles recorded for the company.

Look for entries that name Antony Jonathan Portno and Noreen Mary Portno in the relevant sections to confirm who is recorded on the public register.

Cross-check OLBG site and competition terms

Finally, check the OLBG site footer and the prizes terms and competition terms where the promoter or operator is named; this on-site disclosure should match the Companies House entries if the registry is current.

When you follow these three steps you verify both the statutory record and the public-facing statement from the site itself.

What OLBG’s site and competition terms say about the operator

Footer disclosures

OLBG’s publicly visible site footer includes a statement naming Invendium Ltd as the operating company, which is useful for a quick on-site confirmation when you are cross-checking the company registry.

Site footers are convenient but can be slower to update than the statutory register in some circumstances, so always view both sources.

Prizes terms and promoter statements

The OLBG prizes terms and conditions explicitly identify Invendium Ltd as the promoter for competitions, and that page is a direct place to verify who is named for prize administration and promotional responsibility.

Use the prizes terms when you need to confirm the named promoter for any competition or prize activity on the site because those terms typically state who must fulfil prize obligations.

What this ownership means for users and why it matters

Practical implications

Knowing that Invendium Ltd operates OLBG tells you which legal entity is named for contractual obligations, prize administration, and any formal consumer queries tied to the site.

This matters when you need to direct a complaint, confirm the promoter for a competition, or seek clarification about terms and conditions that govern participation.

Limits of what ownership implies

Ownership or operation by a registered company does not guarantee any particular quality of service, nor does it replace the need to read the site’s terms and conditions and prize rules carefully.

Users should not assume regulatory status or any particular consumer protections beyond what is set out in the site terms and applicable law; ownership simply identifies who is named as the operator.

Decision checklist: when to accept a site ownership claim

Red flags to watch

Be cautious if the company name on the site does not match the Companies House entry or if a promoter is unnamed; mismatches are a common red flag worth investigating further.

Also watch for recent filings in the register that show unexplained changes to officers or PSC details without corroborating on-site updates.

Minimum verification steps

At minimum, compare the Companies House overview, the PSC and officers pages, and the site’s relevant T&Cs or footer; where these three align you have reasonable confirmation of the operator.

If you find discrepancies, save screenshots, note access dates, and consider contacting the company or Companies House guidance for further clarification.

Common errors and misunderstandings when checking ownership

Outdated web pages

Cached or archived versions of pages can show out-of-date company names or promoter statements; always check the live page and note the access date when saving evidence.

Using cached search results without checking the live site is a frequent source of confusion when researching ownership.

Confusing brand and company names

Brand names and trading styles are not the same as legal company names; searching Companies House for the exact registered company name or the company number avoids false matches.

When a site trades under a brand, look for an explicit statement on the site that names the legal operator and then confirm that name on the company register.

Practical walkthrough: verifying OLBG in under 10 minutes

Search by company number

Save the overview URL and note the access date to create a time-stamped record of what the register showed at that moment.

Confirming PSC and officers

Click the PSC tab and the officers tab from the overview and look for the names recorded there; note entries that name Antony Jonathan Portno and Noreen Mary Portno if they appear on those pages.

Saving screenshots of the PSC and officers pages provides clear evidence of who was listed at the time you checked.

Cross-checking site T&Cs

Open the OLBG footer and the prizes terms and compare the named promoter with the Companies House entries to ensure the site’s stated operator aligns with the statutory record.

Keep copies of the site pages or a PDF of the prizes terms with the access date to document the on-site disclosure you used to corroborate the registry entries.

If records change: how to interpret a new filing or owner

Types of filings that indicate ownership changes

Look in the filing history for documents that indicate changes to officers, PSC updates, or formal notices of change of control; these filing types normally accompany ownership or control changes in the register.

When you see a filing that purports to change PSC or officer details, open the filed document to read the submitted evidence and the date it was filed.

Verifying authenticity of filings

Always view the actual filing document in the Companies House filing history rather than relying only on a summary line; the document will show who submitted the filing and the precise changes recorded.

Save a copy of the filing document and note the filing date, because official filings are the primary evidence for changes recorded in the public register.

Sources and how to cite company records correctly

Preferred primary sources

Primary sources for verification are the Companies House company overview, the PSC page, the officers page, and the filing history, together with the OLBG site footer and the prizes terms and conditions.

When citing a source, include the page title, the URL, and the access date so others can follow the same verification steps and see whether entries have changed since you checked them.

Citation examples

For a concise citation, reference the Companies House overview by company name and number and the OLBG prizes T&Cs by page title and access date to provide a complete traceable record.

Keeping the Companies House overview URL and the prizes terms URL with an access date is sufficient for most verification and reporting needs.

Save the URLs and access dates if you need to document your verification or follow up with formal enquiries.

How can I confirm who legally owns OLBG?

Check Companies House for Invendium Ltd using company number 04490764, view the PSC and officers pages, and compare with the OLBG site footer and prizes T&Cs.

Does ownership mean OLBG is regulated in a specific way?

What should I do if the Companies House record and the site disagree?

Save screenshots, note access dates, and contact the listed company or Companies House for clarification if records differ.

If you need formal confirmation for legal or reporting purposes, use the Companies House filings as your primary evidence and retain access dates and screenshots.

Records can change, so treat any verification as a snapshot and note the date you accessed each page.
