Open data

Published: 27 November 2023
Last updated: 9 October 2024

Ofcom follows open data principles, making the data we collect and create available to the public wherever possible.

Open data is data that anyone can access, use or share.

Ofcom’s open data is a mix of data from or about the companies we regulate in the communications sector, and the citizens and consumers who use them. We also use and release other data which is not open.

All of the data available on our website and on other portals is subject to a licence.

Where we can make the data available on an open basis, we use the Open Government Licence, which gives users various freedoms about how they choose to use the data, subject to conditions.

In some cases we have made data available but have with limitations on how it can be used; for example, where some or all of that data is owned by a third party. In these cases we set out in the licence on exactly what basis you can use the data.

This page includes links to most of our datasets which are available with an Open Data licence.

You can see this year's data publications on the statistical release calendar.

Some of these data sets are also available on the main pages for their parent publication, such as Connected Nations 2021 and our telecoms and pay-TV complaints reports.

You can also find them on the data.gov.uk portal, alongside data sets from all central government departments and many other public sector bodies and local authorities.

We are still developing and building our approach to releasing open data. If you have any comments about this page or our approach in general, please email open.data@ofcom.org.uk.

If you have comments or queries about a specific dataset available on this page, or would be willing to share the ways in which you have used the data, please email open.data@ofcom.org.uk. Please set out the dataset you are referring to and include links where relevant.

Broadcast radio transmitters: technical parameters

The following information comprises details of the technical parameters of all analogue VHF, MF, and DAB transmitters (including services on multiplexes) currently on-air. In-use parameters are included mainly for listeners and aerial installers who may wish to know more about the nature of the signals they are receiving and possibly optimise their aerial accordingly. The maximum allowed parameters (within the terms of each licence) for analogue services are also included for the benefit of those, principally in the industry, who wish to make calculations, particularly about interference, for coverage-planning purposes. The format is intended more for ease of download and transfer into specialist databases, than for presentation.

The TxParams data will be refreshed regularly as new transmitters are added, modified, or suppressed.

Telecoms and pay-TV complaints

Complaints recorded by Ofcom against the largest telecoms and pay-TV providers. Since May 2015 we have released these quarterly datasets in csv format.

This information is intended to help consumers make better-informed decisions. We believe that the publication of such information is useful for consumers, especially those who are thinking about changing provider or purchasing a new service. We also believe that publication of provider-specific complaint volumes incentivises providers to improve their performance.

Technology tracker

The technology tracker measures awareness, access, use of and attitudes towards fixed and mobile telecoms, internet, multi-channel TV, and radio, among UK adults (aged 16+). Across the UK overall, and within each UK nation, the tracker provides detailed analysis by key population demographics, sub-region, and by urban vs. rural. It collects data that enable comparisons to be made with older data collected by Ofcom, informing Ofcom analysis, reports and decisions.

Up to and including 2014, there were three waves of research per year: from 2015 to 2017, there were two waves per year, in April and October. From 2018 there will be one wave of research per year.

The data have been published in csv format since 2011. The datasets from 2011 to 2015 inclusive contain the chart data only: from 2016 onwards they will contain all the data from the .spss files.

Children's media literacy

Annual report on children's media literacy in the UK. This report provides detailed evidence on media use, attitudes and understanding among children and young people aged 5-15, as well as detailed information about the media access and use of young children aged 3-4.

The report also includes findings relating to parents' views about their children's media use, and the ways that parents seek - or decide not - to monitor or limit use of different types of media. It is a reference tool for industry, stakeholders and consumers. It also provides context to the work Ofcom undertakes in furthering the interests of consumers and citizens in the markets we regulate.

UK radiowave propagation measurement data for frequencies below 6 GHz

This radiowave propagation measurement data was collected by Ofcom in seven areas of the UK between 2015 and 2018. It is representative of the UK’s diverse topography. Measurements were made at six frequencies between 400 MHz and 6 GHz. All equipment was carefully calibrated allowing the basic transmission loss to be calculated. Ofcom is using the data to assess and improve UK specific performance and applicable frequency ranges of propagation prediction methods, including ITU-R P-series Recommendations.

We are making this data available so that academia and industry can benefit from the data in analysis of their own propagation models. A document, UK radiowave propagation measurement data for frequencies below 6 GHz (PDF, 4.1 MB), provides information on the technical parameters and describes the format of the measurement data files.

Wireless Telegraphy Register

The Wireless Telegraphy Register (WTR) provides information about who is licensed to operate services in specific frequencies, or geographical areas, and the technical parameters associated with those rights of use. Ofcom provides this information under Section 31 of the Wireless Telegraphy Act 2006. The register also fulfils Ofcom's obligations under the Environmental Information Regulations 2004 regarding making information progressively available. Ofcom aims to update this information on a quarterly basis.

Update – 4 April 2024

A new field has been added to the Transmitters/Receivers section, Antenna ERP Type, which sits next to Antenna ERP Unit. The new field will show either ERP or EIRP reflecting what is stored on our licensing database.
