We aim to answer your enquiry within ten working days. However, the more specific and precise your enquiry - the quicker we hope to be able to answer it.

By Email

All emails must include a contact telephone number and also a return postal address or fax number. This is because some data may not be in a format that can be easily emailed. Supplying a telephone number will also ensure that we can contact you quickly, should we need to clarify any aspect of your enquiry.

If your enquiry is about National Statistics please email info@statistics.gov.uk.

If your enquiry is about the registration of births, marriages or deaths or other certificate services please visit the General Register Office.

If your enquiry is about Census 2001 please visit Census advice and services.
