About us

U.DAB Ltd is made up of a consortium of organisations and individuals that have been involved in London radio for over 40 years.

Our founders operated Trial London – a trial of the then new small scale multiplex concept – from October 2015. What was supposed to be nine months, ended up being 10 years.

U.DAB applied for the full-time ‘North London’ licence in July 2023 and was awarded the licence in August 2024. The trial relaunched as the full-time North London multiplex in December 2025, expanding to six transmitters sites from the original three.

U.DAB’s genesis has always been about giving opportunities to smaller broadcasters and our pricing reflects that. C-DSP stations (those that Ofcom has given community status) receive significant discounts. We also provide discounts for smaller stations based locally. The scale of the multiplex – the largest of its kind in the country – means we also host commercial broadcasters keen to reach large numbers of listeners.
