NSS delivers commercial building maintenance, specialist cleaning, platform hire, and equipment testing across the United Kingdom. Operating from strategically located offices in Scotland, the North West, Yorkshire, and the South East, we serve businesses throughout England, Scotland, Wales, and Northern Ireland with consistent, self-delivered service.
Unlike contractors who rely on subcontractors and hired equipment, everything we deliver comes from NSS – our own teams, our own fleet, our own accountability. This direct approach ensures consistent quality whether we’re working at a single site or coordinating maintenance across your nationwide property portfolio.
From 24/7 emergency response to planned maintenance contracts, we combine nationwide coverage with the responsiveness and reliability of a trusted local contractor.
