Since 1970, GAD has been responsible
for providing an independent check on the randomness of the
monthly premium bond prize draw (ERNIE) output.
Statistical
tests are carried out to check that the generation of bond
numbers is free from bias and that each eligible bond has an
equal chance of winning a prize.
We are not involved in Premium
Bond administration and any queries relating to administration
issues should be referred to the National Savings & Investments
Helpline on 0845 964 5000.
National Savings & Investments provide a free tracing
service to enable customers to be reunited with lost
or forgotten savings and investments, including premium
bonds. For more information see the Tracing
Service page of the National
Savings & Investments website.
We can also provide statistical analysis services to other public sector organisations.
