According to NATS' careers site at
http://www.natscareers.co.uk if you click "careers" - "Job Descriptions", click "Controllers", click "Careers FAQs", click "Terms and conditions" and finally click "What are the salary and salary prospects?"
From there I gather that you will not recieve shift pay while validating.
You can download a PDF with this info too located at
