Change of website domain

Request for information – FOI14533


Thank you for your email of 2 March 2015, requesting the following information in accordance with the Freedom of Information Act (FOIA) 2000:

Please inform me of the date (or the dates of the transition period) that the Ordnance Survey website domain changed from .gov.uk to .co.uk, and the reason(s) for the change in internet domain.


I can advise that Ordnance Survey does not hold this information, because Ordnance Survey does not keep information on the exact date of change to the website domain and the reasons for this.

However under our duty to provide advice and assistance as stipulated in Section 16 of the FOIA, we can provide the following explanation which may assist you in this matter.

In 1999, OS became a Trading Fund, required to cover its costs by charging for its products and remit a proportion of its profits to the Treasury. This led to a commercialisation process including the launch of OS MasterMap (launched in November 2001) and culminating in the published address of OS being www.ordnancesurvey.co.uk. I believe that this was during 2003/2004. Unfortunately, as it was over a decade ago, we haven’t been able to find the details of the exact date of the change.
