Today (May 3) marks 70 years since one of the UK’s most important broadcast sites, Winter Hill transmitter in Greater Manchester, was first commissioned. Rising over 1,000 feet above the landscape, the structure has played a central role in the development of television and radio broadcasting for seven decades.
To mark the occasion, footage filmed by a broadcast engineer at more than 300 metres above ground and over 2,500 feet above sea level was released. The footage shows sweeping views across Greater Manchester, Merseyside, Lancashire and Cheshire, highlighting the transmitter’s commanding position above the region.
Winter Hill transmitter: the highest structure in the North West
Located on Winter Hill near Bolton, the mast was commissioned on 3 May 1956 and remains the highest structure in the North West and one of the tallest in the UK. Its scale and prominence have long earned the transmitter the nickname of the “Tower of Power”, reflecting both its physical presence and its broadcasting reach.
Over the years, Winter Hill has been at the centre of major broadcasting milestones. In 1966, a new, higher mast replaced the original structure to improve coverage and capacity, making it the primary transmission site for the North West. In 2009, the mast became the first transmitter in the UK to broadcast digital television in high definition.
Today, Winter Hill delivers TV services to more than 2.7 million homes, reaching around 6.3 million people. The breadth of coverage visible from the top of the mast mirrors the scale of its impact, making it one of the most significant broadcast sites in the UK.
From TV and radio to smart metering networks, the mast has evolved
Operated by Arqiva, the UK’s broadcast infrastructure provider, Winter Hill transmitter continues to deliver Freeview television and DAB digital radio services. It also works alongside a network of relay sites to address coverage challenges created by the region’s varied geography, ensuring reliable access even in harder‑to‑reach areas.
As broadcasting technology evolves, Winter Hill’s role now extends beyond traditional TV and radio. The site also supports smart metering networks, forming part of the national infrastructure that enables energy usage data to be securely transmitted between homes and suppliers.
“Winter Hill has been a cornerstone of broadcasting in the North West – and the UK as a whole”
David John, Director of Sites at Arqiva, said: “Seeing the view at the top of Winter Hill and looking out across the North West is a powerful reminder of just how many communities rely on this site every day. The site has continually evolved to meet audience needs, and it will remain critical not just for broadcasting, but for wider connectivity services that the public depends on.
“Winter Hill has been a cornerstone of broadcasting in the North West – and the UK as a whole – for 70 years, connecting millions of people to trusted TV and radio services through periods of extraordinary technological change.
“From the early days of analogue television to the first HD broadcasts and beyond, the site has continually adapted to meet the needs of audiences. As we look to the future, Winter Hill will continue to play a critical role not just in broadcasting, but in supporting wider connectivity services that communities and industries depend on every day.”
