Part of PTSG – the UK’s leading specialist services provider

Five reasons why NSS provides an altogether better service.

Altogether better

We’ve brought all our services together, so you only need one contact. No more dealing with multiple contractors, it’s just one team, on one site, delivering everything you need.

National coverage

Better coverage means a better service. We have nine sites nationwide, meaning we’re on-hand to offer quick response times 24/7, 365 days a year.


We don’t use subcontractors. We don’t hire equipment. We self-deliver the job in-house, ensuring a consistent service and a rapid response, every time.

The safest way

The safest way is the only way. Our skilled, highly qualified staff work to the strictest standards, and a culture of safety and transparency is built into everything we do.

Transparency matters

That’s why we provide timely and accurate reports throughout the work, giving you the peace of mind of knowing exactly what’s been done. And we use these reports to continuously improve efficiency and quality.
