The Southall Industrial Estate on Trident Way in Southall is to be demolished and replaced with data centres following approval from Ealing Council’s planning committee last month (22 October 2025).
The redevelopment, led by Global Technical Realty (GTR), will see four large data centre units built on the site, alongside a central pavilion and new office spaces.
The site has a long history of industrial and production use and was once home to one of the factories operated by Ticklers Jam, a British preserves brand which operated until the mid-20th century. One of the new buildings will be named the Jam Factory in a nod to this heritage.
Planning permission covers four data centre units (Use Class B8) within three buildings totalling 156,804 sq metres of floorspace, rising up to 37.4 metres in height. The plans also include four industrial buildings (Use Classes B8, B2 and E(g)(iii)) providing a further 21,759 sq metres of space, with heights ranging from 11.3 to 15.5 metres. A central pavilion building (Use Class E(b)) of 193 sq metres will serve as a café and amenity hub for staff and visitors.
Royal London Asset Management Property previously owned the site and sold it to GTR for £315 million in May 2024.
The proposal is expected to deliver major public benefits, including new employment opportunities, affordable workspace, and investment in local skills and infrastructure. It is estimated that the scheme will create around 460 full-time equivalent construction jobs per year and approximately 1,120 operational roles once completed, which Ealing Council said represents an uplift in employment compared with the existing site.
The development would also contribute approximately £14.6 million in annual business rates.
As part of the planning agreement, Global Technical Realty has committed £6.6 million towards a Data Centre Skills and Training Strategy to support local employment pathways in the digital and technology sectors. A further £750,000 will go towards a Local Economy Management Plan to assist existing and returning businesses, while £300,000 has been pledged for off-site flood risk mitigation.
