On 31 May 2007, the UK Department for Transport (DfT), via the [[general lighthouse authority|general lighthouse authorities]], awarded a 15-year contract to provide a state-of-the-art Enhanced LORAN service to improve the safety of mariners in the UK and Western Europe. The service contract was to operate in two phases, with development work and further focus for European agreement on eLoran service provision from 2007 through 2010, and full operation of the eLoran service from 2010 through 2022. The first eLoran transmitter was situated at [[Anthorn Radio Station]] Cumbria, UK, and was operated by [[Babcock International]] (previously Babcock Communications).<ref>{{Cite web | title=The GLAs award a 15-year eLoran contract to Babcock Communications  | publisher=[[Trinity House]]  | date=31 May 2007  | url=http://www.trinityhouse.co.uk/media_centre/press_releases/2007/enhancing_safety_protection_marine_environment_glas_award_15-year_eloran_contract_vt_communications.html  | access-date=27 May 2010  | url-status=dead  | archive-url=https://web.archive.org/web/20110319051314/http://www.trinityhouse.co.uk/media_centre/press_releases/2007/enhancing_safety_protection_marine_environment_glas_award_15-year_eloran_contract_vt_communications.html  | archive-date=19 March 2011  | df=dmy}}

The UK government granted approval for seven differential eLoran ship-positioning technology stations to be built along the south and east coasts of the UK to help counter the threat of jamming of global positioning systems. They were set to reach initial operational capability by summer 2014.<ref>Nautilus International Newspaper August 2013</ref> The general lighthouse authorities of the UK and Ireland announced 31 October 2014 the initial operational capability of UK maritime eLoran. Seven differential reference stations provided additional position, navigation, and timing (PNT) information via low-frequency pulses to ships fitted with eLoran receivers. The service was to help ensure they could navigate safely in the event of GPS failure in one of the busiest shipping regions in the world, with expected annual traffic of 200,000 vessels by 2020.<ref>GPS World.

Despite these plans, in light of the decision by France and Norway to cease Loran transmissions on 31 December 2015, the UK announced at the start of that month that its eLoran service would be discontinued on the same day.<ref>{{Cite web | title=Notice To Mariners  | publisher=[[Trinity House]]  | date=1 December 2015  | url=http://www.trinityhouse.co.uk/mariner_info/notice_to_mariners/e/01122015.html  | access-date=30 December 2015  | url-status=dead  | archive-url=https://web.archive.org/web/20160304112222/https://www.trinityhouse.co.uk/mariner_info/notice_to_mariners/e/01122015.html  | archive-date=4 March 2016  | df=dmy}}</ref> However to allow for further research and PNT development, the eLoran timing signal is still active from the government facility in [[Anthorn Radio Station|Anthorn]].<ref name="GPSWorld">{{cite web|url=https://www.gpsworld.com/with-new-space-program-uk-continues-march-to-more-holistic-pnt/| title=With new space program, UK continues march to more holistic PNT | date=25 September 2020 |publisher=GPS World |access-date=17 November 2021}}</ref>
