GDPR and offshore outsourcing: what UK firms must do

Key takeaways

GDPR offshore outsourcing is lawful and common, but it needs the right paperwork. When a team outside the UK can access personal data you control, UK GDPR treats it as a restricted transfer. For countries without UK adequacy regulations, you need an appropriate safeguard, a transfer risk assessment and a controller-processor contract.

• Remote access by a team abroad counts as a restricted transfer, even if data stays on UK servers.
• Sri Lanka, India and the Philippines have no UK adequacy regulations.
• Use the ICO's International Data Transfer Agreement (IDTA) or the UK Addendum.
• Complete a transfer risk assessment, now called a data protection test in UK law.
• Sign a processor contract with the terms the ICO lists, and update your privacy notice.

Does UK GDPR allow offshore outsourcing?

Yes. UK GDPR does not ban sending personal data abroad or giving overseas teams access to it. It requires that the protection travels with the data. Offshore business process outsourcing (BPO) is lawful when the transfer rules are followed and the provider is bound by a proper processor contract.

This article explains the main steps in plain English. It is not legal advice; for complex or high-risk processing, take specialist advice.

What is a restricted transfer?

A restricted transfer is when personal data subject to UK GDPR is sent to, or made accessible to, a receiver in a country outside the UK. The ICO is clear that making data accessible counts: an offshore team logging into your UK-hosted helpdesk or CRM is receiving a restricted transfer.

Restricted transfers are allowed if the destination has UK adequacy regulations, if an appropriate safeguard is in place, or, in limited cases, if an exception applies. Exceptions are narrow and not suitable for routine outsourcing.

Which countries have UK adequacy?

UK adequacy regulations cover the EU and EEA and a list of other countries and territories the UK has assessed. Common offshore outsourcing destinations such as Sri Lanka, India and the Philippines are not on that list, so transfers to teams there need an appropriate safeguard.

Check the ICO's current list before relying on adequacy, as it can change.

What are the IDTA and the UK Addendum?

The International Data Transfer Agreement (IDTA) is a standard contract issued by the ICO that a UK exporter and an overseas importer sign to protect a restricted transfer. The UK Addendum is an alternative that adds UK terms to the EU standard contractual clauses, useful when a provider already uses the EU clauses.

Either works as an appropriate safeguard. The provider should be familiar with them and ready to sign. If it is not, that tells you something about its maturity.

What is a transfer risk assessment?

A transfer risk assessment (TRA) checks whether the protection in the IDTA or Addendum will work in practice in the destination country, considering local laws and the safeguards around the data. The ICO notes that UK legislation now refers to this as a "data protection test", following the Data (Use and Access) Act 2025.

For routine support and admin work where the team works inside your UK systems under strong access controls, the assessment is often straightforward. Record it, and review it if the processing changes.

What must the processor contract include?

Separately from the transfer safeguard, UK GDPR requires a written contract between you (the controller) and the provider (the processor). The ICO lists the minimum terms.

• Process data only on your documented instructions.
• Confidentiality duties for everyone handling the data.
• Appropriate security measures.
• Rules for using sub-processors.
• Help with individuals' rights requests and with breaches.
• Deletion or return of data at the end of the contract.
• Audit and inspection rights.

• BPO contract terms to check before signing

How do practical controls reduce the risk?

Paperwork is necessary but not sufficient. Keep the team working inside your systems rather than on exported copies, give each person an individual login with multi-factor authentication and least-privilege permissions, restrict downloads and exports, and keep activity logs. These controls make the transfer risk assessment easier and actual breaches less likely.

Security matters: the DSIT Cyber Security Breaches Survey 2025/2026 found 43% of UK businesses reported a breach or attack in the previous year.

• Data security with an outsourced team

Are there special rules for sensitive data?

Yes. Special category data, such as health information, needs an additional condition for processing and deserves stronger controls. Healthcare providers with access to NHS patient data must also meet the NHS Data Security and Protection Toolkit standards. Financial services firms have FCA outsourcing expectations to consider. For these, take specialist advice before offshoring.

What does this look like in practice?

At Global Bridge Labs (GBL), access is role-based and logged, work runs inside the client's systems rather than copies of their data, and every process is written down. We work to UK GDPR requirements and sign a data processing agreement, with the transfer safeguard needed for delivery from Sri Lanka.
