• OCS Agrees Integrated FM Deal With Merlin Entertainments 

19 December 2025

OCS has been appointed by Merlin Entertainments to deliver integrated facilities management services across 12 of its UK attractions, including Alton Towers.

The five-year deal will see OCS covering a range of services including building maintenance, cleaning, security, waste management, landscaping and pest control. The contract spans Alton Towers Resort, Legoland Windsor Resort, Chessington World of Adventures Resort, Thorpe Park, Warwick Castle, two Sea Life sites, the London Eye, Madame Tussauds, Shrek’s Adventure! and The London Dungeon. 

Alongside FM delivery, OCS will support Merlin’s aim to be carbon neutral by 2030 and adopt full LED lighting by 2027. 

Merlin employees working in these areas transferred to the OCS team on 1 December 2025. 

Mike Vallis, Merlin’s SVP Managing Director for the UK, said: “Our priority is creating unforgettable experiences for those visiting our attractions.  Partnering with OCS – with their proven expertise in guest-focused environments like ours – allows us to simplify operations, drive consistency and ensure our facilities at these sites are safe, clean and maintained to the highest standards. 

“Those colleagues who are now part of OCS will continue to work alongside Merlin’s in-house teams, who will remain focused on delivering magical days out and immersive shorts breaks for families at these attractions. This close collaboration will be particularly important for those working in our technical services and engineering teams, who will see their expertise in areas such as ride maintenance being complemented by the input provided by colleagues working under OCS’s leadership.”
