Virtus LONDON5, 6, 7 & 8, Stockley Park Campus

Colo-X analysis

The Virtus Stockley Park Data Centre Campus consists of four huge data centres buildings that opened from 2019 onwards. The smaller two, LONDON6 and LONDON8 are aproximately 80,000 sq ft of net technical capacity or 16MW each whilst the larger two, LONDON5 and LONDON7 are over 100,000 sq ft each and provide 28MW of IT load. We believe each building is leased to a single occupier under a long term contract, so this is very much a wholesale focussed or “hyperscale” campus.

Virtus do offer smaller retail focussed colocation capacity, as racks, cages or contained pods in other their other locations, either directly or via other customers.

Virtus LONDON5, 6, 7 & 8, Stockley Park facility description

The Virtus Stockley Park data centre campus is located around 5km/3 miles due north of London’s Heathrow airport or 12km/8 miles due east of the Slough Trading Estate where Virtus run four existing data centres (LONDON3, 4, 9 and 10). Junction 4 of the M4 motoraway is 1.5 miles away. The site was originally developed for four large logistic warehouses by specialist developer Prologis who named the site Prologis Park West London and Virtus leased the first two buildings at the end of 2017 before taking over the entire development for data centre use.

Virtus are one of the fastest growing UK data centre operators, with 11 massive facilities either open or under construction in the London market providing a combined 175MW or 850,000 sq ft of net technical capacity.  Their primary focus today is the 9 data centres in West London, with four of a combined 84MW in Stockley Park (LONDON5, 6, 7 and 8) and five on the Slough Trading Estate offering 75MW (LONDON3, 4, 9, 10 and 11), with the original small 6MW site in Enfield LONDON1 and LONDON2 in Hayes (12MW).

Virtus became a wholly owned subsidiary of ST Telemedia in October 2017, an investment vehicle of the Government of Singapore, with Macquarie Asset Management then acquiring a 40% minority stake in August 2022.

Virtus have had enormous success in the booming demand from hyperscale cloud providers that has arisen since 2016 and most of their recent developments are believed to have been leased on a single tenant basis to these large scale users. In the year ending December 2021, 75% of Virtus’s revenue came from just the three large customers (whom we would guess at being Google, Amazon and Microsoft/Azure), so demonstrating their focus on the very largest wholesale users.
