Terms & Conditions

Certificate of Sponsorship Document Integrity & Tamper Analysis

Effective Date: 25 October 2026

These Terms and Conditions (“Terms”) govern the independent document integrity and tamper-analysis service (“Service”) provided by Check Your Sponsor, operating through checkyoursponsor.co.uk (“we”, “us”, or “our”).

Please read these Terms carefully before purchasing the Service.

By placing an order and expressly accepting these Terms, you agree to be bound by them.

Nothing in these Terms excludes or limits any consumer rights that cannot lawfully be excluded under applicable law.

1. Nature of Our Service

1.1. We provide a one-time technical analysis of customer-submitted Certificate of Sponsorship (“CoS”) documents, PDFs and related files.

1.2. The Service examines observable technical, structural and visual characteristics of the submitted document to identify potential indicators of editing, alteration, fabrication, manipulation or inconsistency.

1.3. The Service is provided on a per-document basis. Unless expressly stated otherwise, it is not a subscription, ongoing monitoring service or continuous verification arrangement.

1.4. Our analysis is limited to the file submitted and the techniques reasonably available to us.

1.5. The Service is not an official immigration verification, legal assessment or government certification.

1.6. We will perform the Service with reasonable care and skill in accordance with applicable consumer law.

2. No Guarantee of Document Authenticity

2.1. Our Service cannot conclusively establish whether a document is genuine, legally valid or officially recognised by UK Visas and Immigration (“UKVI”) or the UK Home Office.

2.2. A finding that no apparent evidence of manipulation was detected does not guarantee authenticity.

2.3. A document may appear technically consistent while containing inaccurate information or relating to an invalid, cancelled, withdrawn or non-existent sponsorship record.

2.4. Similarly, detected irregularities do not automatically establish that a document is fraudulent.

2.5. Legitimate documents may contain unusual formatting, metadata or technical characteristics.

2.6. No technical document-analysis method can guarantee detection of every possible alteration, fabrication or misrepresentation.

3. Official Certificate of Sponsorship Verification

3.1. A Certificate of Sponsorship is fundamentally an electronic record created and assigned through the relevant UK sponsorship system.

3.2. A PDF, printout, screenshot or other representation of a CoS does not, by itself, establish the existence or validity of its underlying official record.

3.3. We do not claim access to restricted Home Office or UKVI sponsorship databases.

3.4. We cannot confirm whether the underlying official record exists, remains assigned, has been cancelled or is currently valid.

3.5. Official confirmation must be obtained through appropriate authorised channels, including the relevant sponsoring organisation and competent UK authorities where applicable.

3.6. Our technical analysis must not be presented as official CoS verification.

4. Scope of Technical Analysis

4.1. Depending on the submitted file and its technical characteristics, the Service may examine:

• Document metadata;
• PDF structure and editing indicators;
• Font and formatting inconsistencies;
• Text alterations;
• Image manipulation indicators;
• Suspicious structural changes;
• Inconsistent dates and information;
• Apparent additions or deletions;
• Copy-and-paste artefacts;
• Unusual file characteristics; and
• Other observable indicators of possible document modification.

4.2. Not every technique will necessarily be applied to every file.

4.3. Certain types of manipulation may not leave detectable evidence.

4.4. Our Service does not include unrestricted forensic investigations or official database access. Where the selected package expressly includes contacting a named employer, this is an additional attempt to obtain clarification, not official verification of a CoS. We cannot guarantee an employer response, and a lack of response is not proof of fraud.

4.5. Any assessment is limited to the material supplied and the evidence reasonably available.

5. Interpretation of Assessment Results

5.1. Reports describe observed technical findings and potential document-integrity concerns.

5.2. We do not issue legally binding declarations that a document is genuine, fraudulent or officially valid.

5.3. Expressions such as “No obvious indicators detected”, “Potential manipulation detected” or “Further verification recommended” describe technical observations only.

5.4. These expressions must not be interpreted as official confirmation of authenticity, fraud or visa eligibility.

5.5. Customers acknowledge that both false-positive and false-negative findings are possible.

5.6. Our findings are subject to the limitations stated in the report and these Terms.

6. Customer Responsibilities

6.1. Customers must have the lawful right or appropriate authority to submit the relevant document and any personal information it contains.

6.2. Customers must not knowingly submit documents obtained unlawfully or without appropriate permission.

6.3. You may submit a document you suspect has been edited or fabricated for genuine analysis. Customers must not use the Service to assist fraud or knowingly misrepresent their authority to submit a document.

6.4. Customers are responsible for ensuring that their submissions comply with applicable law and do not infringe third-party rights.

6.5. We may refuse or suspend a request where we have reasonable grounds to suspect fraud, unlawful activity or misuse.

6.6. Any refusal or suspension will be handled fairly and subject to applicable consumer rights.

6.7. Nothing in this Section removes our responsibility to exercise reasonable care and skill.

7. No Immigration or Legal Advice

7.1. Our Service is restricted to independent technical document analysis.

7.2. We do not provide regulated immigration advice, legal representation or visa application services.

7.3. We do not determine whether an individual satisfies UK immigration requirements.

7.4. We do not advise customers whether to submit, withdraw or amend a particular immigration application.

7.5. Our reports must not be interpreted as individual immigration advice.

7.6. Customers requiring immigration or legal advice should consult an appropriately authorised professional.

7.7. We will not undertake activities requiring regulatory authorisation unless the necessary authorisation is held.

8. No Guarantee of Visa or Employment Outcomes

8.1. Our Service does not guarantee:

• UK visa approval;
• Acceptance of a CoS by UKVI;
• Validity of a sponsor licence;
• Legitimacy of an employer;
• Accuracy of official sponsorship records;
• An employment offer;
• Permission to enter or remain in the UK; or
• Any immigration or financial outcome.

8.2. A document may pass technical analysis while remaining legally invalid or unsuitable for an immigration application.

8.3. Decisions by UKVI, the Home Office, employers and other independent parties are outside our control.

9. Submitted Documents and File Quality

9.1. We analyse the file actually submitted by the customer.

9.2. Poor-quality scans, screenshots, corrupted files, incomplete documents, compression and missing information may restrict the analysis.

9.3. We may request a clearer or replacement file where reasonably necessary.

9.4. Customers should avoid submitting unrelated or unnecessary personal information.

9.5. If a file is technically inaccessible or cannot reasonably be analysed, we may decline to proceed and provide an appropriate remedy in accordance with applicable law.

9.6. We preserve the original uploaded PDF without compression, conversion or re-saving. A checksum is recorded for file integrity. This does not establish authenticity. Keep your private tracking link confidential. For access, retention or deletion questions, contact admin@checkyoursponsor.co.uk. Section 13 explains our data-protection commitments.

10. Reports and Results

10.1. Following completion of the assessment, we will provide a report summarising the technical findings.

10.2. Reports may identify potential irregularities, detected inconsistencies, limitations or the absence of obvious indicators.

10.3. An inconclusive result is a possible outcome of a properly performed technical assessment.

10.4. We do not guarantee that every assessment will produce a definitive finding.

10.5. A report represents the technical findings based on the material reasonably available at the time of analysis.

10.6. Reports do not constitute official verification or certification.

10.7. Our responsibility to exercise reasonable care and skill remains unaffected by these limitations.

11. Use of Reports

11.1. Reports are provided for personal informational and document-review purposes.

11.2. Customers may share unaltered reports with appropriate professionals, sponsoring organisations or relevant authorities where lawful.

11.3. Customers must not modify or misrepresent a report to create a misleading impression.

11.4. Reports must not be presented as official government certifications.

11.5. Reports must not be used to make knowingly false allegations of fraud against another person or organisation.

11.6. We grant customers permission to use their reports for the purposes described above.

11.7. Ownership of the submitted document remains with its lawful owner.

12. Independent Service and Government Affiliation

12.1. We operate as an independent service provider.

12.2. We are not affiliated with, endorsed by or authorised to act on behalf of the UK Home Office, UKVI or another UK Government department.

12.3. We do not issue, assign, amend, approve or cancel Certificates of Sponsorship.

12.4. We cannot determine a person's immigration status or visa eligibility.

12.5. References to government organisations are made for identification and explanatory purposes only.

13. Data Protection and Confidentiality

13.1. Submitted documents may contain personal information, including names, dates of birth, nationality, passport details and employment information.

13.2. We will process personal information in accordance with applicable data-protection law, including the UK GDPR and Data Protection Act 2018 where applicable.

13.3. We use the contact details, documents, employer information, order and payment records, correspondence and assessment results you provide to fulfil your order, provide tracking and reports, answer enquiries and handle complaints. We rely on performance of our contract for the requested Service, legal obligations where applicable, and legitimate interests in securing the Service and preventing misuse where those interests do not override your rights.

13.4. Access to customer information will be limited to authorised persons and systems where reasonably necessary for legitimate purposes.

13.5. We will not publicly disclose customer documents or sell their contents as a commercial data product.

13.6. Authorised service providers support database and file storage (Supabase), email (Hostinger), hosting and the payment provider you select at checkout. Payment details are handled by the payment provider; our application receives transaction references and payment status rather than your card details. Where a package includes employer contact, we share only the information reasonably necessary for that enquiry. Any international transfers or third-party processing will be subject to applicable legal requirements.

13.7. We keep personal information only for as long as reasonably necessary for the Service, handling enquiries or disputes and meeting applicable legal obligations. You may contact admin@checkyoursponsor.co.uk to ask about retention or exercise applicable rights of access, correction, erasure, restriction, objection and data portability. These rights may be subject to lawful exceptions. You may also complain to the Information Commissioner’s Office at https://ico.org.uk/make-a-complaint/ where UK data-protection law applies.

13.8. This Section provides the data-protection information for this Service. Contact admin@checkyoursponsor.co.uk with privacy questions before submitting unnecessary personal information.

14. Security of Submitted Files

14.1. We will implement appropriate technical and organisational security measures for the information we process.

14.2. Such measures are intended to protect submitted materials against unauthorised access, disclosure, alteration and accidental loss.

14.3. No electronic system can be guaranteed to be completely free from security risks.

14.4. This acknowledgement does not exclude our obligations under applicable data-protection or consumer law.

14.5. We will assess and respond to security incidents in accordance with applicable legal requirements.

15. Accuracy and Technical Limitations

15.1. Technical analysis is inherently subject to limitations.

15.2. Factors affecting the analysis may include:

• Document resolution;
• Scanning;
• Compression;
• Missing pages;
• File conversion;
• Previous alterations;
• Incomplete metadata;
• Legitimate differences in document structure; and
• Limitations of available analysis methods.

15.3. Sophisticated alterations may not be detectable using the available methods.

15.4. Legitimate documents may exhibit characteristics commonly associated with editing.

15.5. Consequently, the Service cannot guarantee error-free conclusions.

15.6. These limitations do not remove our responsibility to perform the agreed Service with reasonable care and skill.

16. Customer Decisions and Independent Verification

16.1. Customers should not rely exclusively on our report when making immigration, employment or financial decisions.

16.2. Customers remain responsible for deciding whether to:

• Submit a visa application;
• Pay an employer, recruiter or intermediary;
• Accept employment;
• Travel to the UK; or
• Disclose additional personal information.

16.3. Independent verification through appropriate official channels is strongly recommended where necessary.

16.4. We are not responsible for losses caused solely by independent third-party decisions or circumstances for which we are not legally responsible.

16.5. Nothing in this Section excludes liability for our own breach of contract, negligence or another legally actionable failure.

17. Fees, Immediate Service Delivery and Refunds

17.1. One-Time Service

The Service is purchased on a one-time, per-document basis.

The fee covers the technical assessment of the submitted file and preparation or delivery of the corresponding report.

Unless expressly stated otherwise, no recurring subscription or continuing monitoring is included.

17.2. Payment

The total payable price, including applicable taxes and compulsory charges, will be shown before payment.

Customers must expressly acknowledge their obligation to pay before placing an order.

17.3. Immediate Commencement

The Service begins after successful payment and receipt of a suitable document. The selected package description shows the estimated review time. Estimates are not guaranteed deadlines; requests for clarification or an employer response can take longer.

Where a statutory cancellation period applies, we will obtain the customer's express request to begin performance during that period.

We will also obtain the required acknowledgement that the statutory cancellation right will be lost once the Service has been fully performed, where the legal requirements for that consequence are satisfied.

17.4. Completion of the Service

The Service is ordinarily completed when the agreed technical assessment has been performed and the corresponding report has been made available or delivered to the customer.

If the report has not been supplied as agreed, the Service will not be treated as fully performed merely because an internal scan has started or finished.

17.5. No Voluntary Refunds After Completion

Because the Service consists of a one-time technical assessment and report, we do not offer voluntary change-of-mind refunds after the Service has been fully performed.

A customer is not entitled to a discretionary refund solely because:

• The report identifies no obvious irregularities;
• The report identifies possible manipulation;
• The findings are inconclusive despite a properly performed assessment;
• The report does not support the customer's expectations; or
• The customer subsequently decides that the report is no longer needed.

This policy applies only to the extent permitted by applicable law.

17.6. Statutory Cancellation Rights

Where the UK statutory cancellation right applies to this service contract, you can normally cancel within 14 days after the day the contract is entered into, without giving a reason. Email admin@checkyoursponsor.co.uk with a clear cancellation request and your order reference. You may use the model notice below, but you do not have to. This right remains effective unless and until the applicable legal conditions for its expiry have been satisfied.

For qualifying service contracts, the statutory cancellation right may be lost once the Service has been fully performed following the customer's valid express request and acknowledgement.

If a customer cancels before full performance while a statutory cancellation right remains available, any charge for work already supplied will be determined in accordance with applicable law.

Where a component of the transaction is legally classified as digital content rather than a service, the applicable rules governing digital-content supply and cancellation will apply.

17.7. Service Failures and Statutory Remedies

Nothing in this policy removes a customer's legal rights where:

• The purchased Service is not provided;
• The Service is materially different from its agreed description;
• The Service is not performed with reasonable care and skill; or
• Another statutory remedy is required by law.

Where applicable, we may provide repeat performance or an appropriate price reduction, including a refund where legally required.

17.8. Unusable Documents

If a submitted file is corrupted, unsupported or unsuitable for meaningful analysis, we may request a replacement file.

Where the agreed Service cannot be provided, we will offer an appropriate remedy in accordance with applicable law.

17.9. Refund Processing

Where a refund is legally due, it will be processed within the applicable statutory timeframe using the original payment method unless another lawful arrangement is expressly agreed.

17.10. Contact

Cancellation requests, service complaints and statutory remedy requests may be submitted to:

admin@checkyoursponsor.co.uk

Nothing in this Section excludes or restricts any mandatory consumer right.

18. Limitation of Liability

18.1. We will perform the Service with reasonable care and skill.

18.2. We do not guarantee that a document is genuine, officially valid or acceptable for immigration purposes.

18.3. We are not responsible for losses that are not caused by our breach of contract, negligence or another legally actionable failure.

18.4. We are not responsible for independent decisions made by government authorities, employers, recruiters or other third parties, except to the extent that applicable law makes us responsible.

18.5. We remain responsible for losses resulting from our breach of contract where recoverable under applicable law.

18.6. Nothing in these Terms excludes or restricts liability for:

• Death or personal injury caused by negligence;
• Fraud or fraudulent misrepresentation;
• Statutory consumer rights that cannot lawfully be excluded;
• Failure to exercise reasonable care and skill where exclusion is prohibited; or
• Any other liability that cannot legally be excluded.

18.7. All liability provisions will be interpreted only to the extent permitted by applicable law.

19. Third-Party Information

19.1. Our analysis may involve information obtained from customers, public resources or independent third parties.

19.2. We do not control changes to external websites, government publications or third-party records.

19.3. We will exercise reasonable care when using third-party information relevant to the assessment.

19.4. We do not guarantee the accuracy or continued availability of information controlled by independent third parties.

19.5. External service disruptions or events outside our reasonable control may affect processing times.

19.6. Such circumstances do not automatically exclude statutory remedies.

20. Changes to These Terms

20.1. We may update these Terms to reflect legal, operational or service-related changes.

20.2. Updated Terms will be published with an effective date.

20.3. Changes will not retrospectively remove contractual or statutory rights already acquired by customers.

20.4. The Terms applicable to a purchase will normally be the version presented and accepted when the contract was formed.

20.5. Material changes to existing contractual obligations will be handled in accordance with applicable law.

21. Acceptance and Contract Formation

21.1. Customers must have an opportunity to review the Service description, total price, these Terms and relevant cancellation information before purchasing.

21.2. By accepting these Terms, customers acknowledge that:

• The Service is an independent technical assessment;
• It is not an official CoS verification service;
• The result does not guarantee authenticity or validity;
• The Service does not provide immigration advice;
• No visa or employment outcome is guaranteed;

21.3. The contract is formed when we accept the customer's order.

21.4. We will provide an appropriate confirmation through a durable medium, such as email, in accordance with applicable law.

21.5. Where necessary, separate express consent and acknowledgement will be obtained for immediate service performance and any applicable digital-content supply.

21.6. General acceptance of these Terms does not replace any separate consent required by law.

22. Governing Law and Disputes

22.1. These Terms are governed by the laws of England and Wales, except where mandatory law requires otherwise.

22.2. Consumers retain any mandatory rights available under applicable law.

22.3. Disputes are subject to the jurisdiction of the courts of England and Wales, subject to mandatory rules protecting consumers' rights to bring or defend proceedings elsewhere.

22.4. Customers are encouraged to contact us first so that we can investigate and attempt to resolve any complaint fairly.

22.5. Nothing in these Terms prevents customers from pursuing legal remedies through a competent court or another legally available process.
