Specialist contractor future-proofs Centre Court and Court No. 1 with cutting-edge siphonic drainage technology
NSS, a PTSG Company and leading specialist services provider, has successfully completed a prestigious roof drainage system upgrade at the All England Lawn Tennis Club, home to The Championships, Wimbledon. The comprehensive project involved upgrading the drainage systems on both Centre Court and Court No. 1 to meet current British Standards while preserving the venue’s world-renowned heritage.
Project Tackles Critical Infrastructure Challenge
Following the 2024 Championships, NSS was selected to undertake essential roof drainage assessments and upgrade works across Wimbledon’s two most prestigious courts. The project addressed multiple technical challenges, including ensuring compliance with BS8490:2025 standards for rainfall protection and managing the complex scheduling requirements around the tennis calendar.
“When you’re working at the world’s most famous tennis venue, there’s absolutely no room for compromise. This project required exceptional technical expertise combined with meticulous attention to detail to preserve Wimbledon’s sporting heritage while ensuring future resilience.”
Billy Gordon Technical Manager and Siphonic Drainage specialist at NSS.
Three-Phase Approach Delivers Excellence
NSS implemented a comprehensive strategy spanning multiple phases:
- Assessment Phase: The team conducted extensive surveys including detailed testing of existing gutter systems, comprehensive assessment of siphonic roof drainage systems, and identification of defective areas requiring attention.
- Planning Phase: Based on survey findings, NSS was awarded the full contract covering complete gutter refurbishment works, siphonic roof drainage system upgrades, and remedial repairs across both courts.
- Implementation Phase: The upgrade works included complete gutter renovation, siphonic drainage enhancements to meet compliance standards, targeted repairs to identified problem areas and rigorous quality assurance testing.

The project achieved significant outcomes for the prestigious venue. NSS surveys and reporting confirmed that both Centre Court and Court No. 1 drainage systems now fully comply with BS8490:2025 standards, providing robust protection against extreme rainfall events.
