The main contractor wants ISO 45001 before they'll let you on site. We get you certified.
A principal contractor or public-sector client puts ISO 45001 on their pre-qualification list, and your SSIP accreditation alone no longer clears the bar. The work is there. The certificate is in the way. And the deadline belongs to them, not you. Your named consultant runs the full journey, from gap analysis to certificate, with a system built for a real site.

Built for construction, joined up with the rest of your compliance.
The international standard for occupational health and safety management.
Certification proves, through an independent audit, that you run a managed system for keeping people safe. It's recognised worldwide and has become a common condition in construction, manufacturing and any sector where the work carries real risk.
You identify the health and safety hazards in how you actually work, on site and in the office, rather than guessing or copying someone else's list.
You put genuine controls in place and run them day to day, so safety is managed actively rather than filed in a folder and forgotten.
Your site and office teams have a part in how safety works, which is exactly what an auditor checks when they ask how the system runs in practice.
The standard expects you to review, learn and get better, not pass a paperwork check once and stand still until the next visit.
You get Gary, and you keep him.
The same consultant runs your gap analysis, builds the system, walks your site team through their part, sits both stages of the audit with you, and comes back for surveillance. No rota, no new face every visit, nobody who's never seen your site signing off how you manage it. He builds a safety management system that reflects life on site, not a desk, and he knows what main contractors actually check at pre-qualification. Because Spectra also runs your CDM and SSIP work, the same firm keeps your whole compliance picture joined up, and we stay on after the certificate, not just up to it.
The ISO specialist you'll actually work with.
Your consultant is Gary. He runs the full ISO 45001 journey for you, learns your sites and your people, and where a contract is waiting on the certificate he's certified firms quickly to keep the job live.
“A main contractor's auditor will ask your site team how the system actually works. So I build one that reflects life on site, not a desk.”

This trips up a lot of contractors. They are not the same thing, and one does not replace the other. The good news is they overlap, so a well-built 45001 system makes your SSIP renewals far easier, and we can run both so the evidence does double duty.
Safety Schemes in Procurement, like CHAS, SafeContractor and SMAS, check your health and safety paperwork against a set standard so a client can tick you off as a competent contractor. It gets you through the supplier gate on most UK jobs.
An international management-system standard. It isn't about passing a paperwork check once a year; it's about running an active, audited system that manages safety day to day and improves it over time.
SSIP clears pre-qualification. ISO 45001 is what larger clients, major frameworks and international work increasingly demand on top. Tell us who you're bidding to and we'll tell you straight which you need.
The full journey, from gap analysis to certificate and beyond.
We run the whole thing with one named consultant. Spectra prepares you for certification but does not award the certificate. That comes from an independent, UKAS-accredited certification body that audits you separately, and that independence is what gives it weight at pre-qualification.
ISO 45001, run alongside ISO 9001 and 14001.
We run ISO 45001 as part of an integrated system, on top of ISO 9001 and ISO 14001 rather than on its own. Ongoing management for all three runs from £217 a month + VAT. Prices exclude VAT.
Quality management on its own — the standard most clients start with.
Quality and environmental management run as one integrated system.
All three standards run as a single integrated management system — quality, environmental and safety.
