AI data annotation and data labelling in the UK and Europe
A buyer's guide to GDPR-compliant AI data annotation and data labelling in the UK and Europe, covering modalities, quality, model evaluation, RLHF and cost.
Corpshore UK · 3 July 2026
If you are training or evaluating a model and need labelled data handled under UK and EU rules, you need an annotation partner that combines trained annotators, quality controls and GDPR-compliant data handling. Corpshore provides data annotation, model evaluation and RLHF across image, video, text, audio and sensor data, with UK GDPR-compliant handling of sensitive training data throughout.
What is data annotation, and what can be labelled?
Data annotation is the labelling of raw data so a model can learn from it. That covers image and video (bounding boxes, segmentation, keypoints), text (entities, intent, sentiment, classification), audio and speech (transcription, diarisation), and sensor data for robotics and autonomous systems.
Why does GDPR matter for data labelling?
Training data is often personal or sensitive. Under UK GDPR you need controls suited to the sensitivity of the data, clear records of processing, and, where required, the ability to work inside your own environment. A provider that treats data protection as an afterthought is a liability, not a partner.
What about model evaluation and RLHF?
Good models need more than labels. Corpshore provides model evaluation, red-teaming and reinforcement learning from human feedback, so you can measure quality against a baseline and improve it rather than shipping on a single launch.
How much does data annotation cost?
Cost depends on the modality, the complexity of each label, the quality bar and the volume. Simple text classification is inexpensive per item; detailed video segmentation or expert review costs more. The useful comparison is delivered cost per accepted label at your required quality, not a headline per-hour rate. We confirm an indicative figure for your project and the exact number in a quote.
What to look for in an annotation partner
- UK and EU data residency options and UK GDPR-compliant handling
- Coverage across the modalities you actually use
- A measurable quality process, not just throughput
- Model evaluation and RLHF alongside labelling
- The ability to scale a team up and back down as your project changes
Tell us the modality, volume and quality bar, and we will send an indicative plan within six hours.
