The compliance side of the job, handled by people who've been on site.

You won a job and the client wants SSIP evidence by Friday. A project tipped into notifiable and someone has to be the Principal Designer. A Tier 1's auditor is coming and your folders don't match the deck. Spectra handles the lot from one place, and the consultant you speak to has worked in construction, not just read about it.

WHERE CONTRACTORS CALL US

The compliance demands don't arrive one at a time, and rarely when you've a spare afternoon.

Most enquiries start with one of these. The earlier we're in, the less unpicking there is later — a readiness check now beats a scramble the week the auditor lands.

A client wants evidence you can't produce

A main contractor has asked for SSIP, ISO or safety evidence in a format your current system can't generate, and the tender clock is running.

A project has triggered CDM

The job tipped over into notifiable and the client needs a Principal Designer appointed. Now someone has to carry the duty properly.

An audit or inspection is coming

A Tier 1 auditor is booked, or has just found gaps between your paperwork and what's actually happening on the deck.

You're bidding above your usual size

The prequalification for a bigger contract needs stronger compliance evidence than the systems that got you this far can show.

H&S has landed on the wrong desk

It's ended up with someone who didn't sign up for it and can't evidence competence when a client or the HSE asks.

WHAT WE COVER FOR CONSTRUCTION

SSIP, Principal Designer and site H&S are three different things. Here's each, kept separate.

These get lumped together, and it's confusing unless you already know the jargon. They're not the same job: SSIP is accreditation to get you onto tender and PQQ lists; the Principal Designer role is a legal duty on a project; and general health & safety is keeping people safe on site day to day. We cover all three — and because it's one supplier, the paperwork lines up instead of you stitching three opinions together the night before a deadline.

01Construction health & safety (keeping people safe on site)

The day-to-day safety of the job: risk assessments, method statements and construction phase plans written for the actual work. Site inspections and audits with reports you can act on. Accident investigation and RIDDOR. Your named consultant acts as your competent person, so the legal duty sits with someone qualified.

Construction H&S support
02Principal Designer (CDM & BSA) — your legal duty on a project

A distinct legal role, not the same as general H&S. CDM 2015 applies to every project, whatever the size. We act as your Principal Designer, compile the pre-construction information, handle the F10 where a project is notifiable, and keep the duty-holder roles clear so nobody gets caught out mid-job.

Explore CDM & PD
03SSIP accreditation (getting onto tender & PQQ lists)

Accreditation, not a safety inspection: CHAS, SafeContractor, Constructionline, SMAS Worksafe, Achilles, Acclaim. We're scheme-agnostic. We tell you which one wins the contracts you're chasing, then prepare the evidence so you pass first time rather than bouncing back with actions.

Explore SSIP
04ISO 45001 (the H&S management standard clients ask for)

The occupational health and safety management standard that bigger clients and frameworks increasingly expect. We run it from consultancy and gap analysis through to certification and surveillance, not just the gap analysis.

05Construction HR (the employment side of a site team)

Contracts for a site-based workforce, subcontractor and self-employed status questions, disciplinary and grievance, and TUPE on contract transfers. The employment side that comes with a site-based team.

GENERAL CONSTRUCTION H&S

The day-to-day safety work, done properly — not just the CDM paperwork.

Most of construction health & safety isn't the notifiable-project stuff; it's the routine that keeps people safe and keeps you off the HSE's radar. This is the ongoing support your named consultant provides, whether or not a project triggers CDM.

Site inspections & audits

Planned and unannounced site inspections and safety audits, with risk-ranked findings, photographic evidence and a clear action plan you can actually work through — not a 40-page list that paralyses you.

RAMS written for the real job

Risk assessments and method statements built around how the work actually runs on your site, plus COSHH and task-specific controls, rather than generic templates a client's auditor will see straight through.

Your competent person

We act as your competent person under the Management Regs, so the legal duty sits with someone qualified — and you have a named expert to call when something lands that you weren't expecting.

Accident investigation & RIDDOR

First response when something goes wrong, root-cause investigation, corrective actions, and RIDDOR reporting handled correctly so a bad day doesn't become an enforcement problem.

Toolbox talks & training

Short, engaging briefings and competency checks for supervisors and operatives, so the controls on paper are the controls being used on the deck.

Ongoing compliance oversight

Action trackers, review schedules and straightforward reporting, so standards hold between visits and you can evidence it when a Tier 1 auditor or the HSE asks.

QUESTIONS

Construction compliance questions

Do we need SSIP accreditation to win construction work?
For a lot of clients, yes. Public-sector frameworks, Tier 1 contractors and increasingly Tier 2 clients want SSIP-recognised accreditation such as CHAS, SafeContractor or Constructionline before they'll let you bid. The schemes are largely equivalent at the core stage-one level, so the question is which one your target clients ask for. We help you pick the right scheme for the work you're chasing and prepare the evidence so you pass first time.
Does CDM 2015 apply to small jobs?
Yes. CDM 2015 applies to all construction projects regardless of size or duration. The parts that scale are the duties: a single-contractor domestic job carries fewer formal requirements than a multi-contractor commercial one, but pre-construction information and a construction phase plan are still expected. The common mistake is assuming the rules only bite on large projects. They don't.
What does a Principal Designer actually do on a construction project?
Under CDM 2015, the Principal Designer plans, manages and coordinates health and safety during the pre-construction phase: the design and planning stage before work starts on site. They identify foreseeable risks, make sure designers reduce them, compile the pre-construction information and feed it to the Principal Contractor. We can act as your appointed Principal Designer, or support your in-house team to carry the role properly.
Can one firm handle our CDM, H&S and SSIP together?
Yes, and that's most of the point. On a construction project these overlap constantly. The same consultant can act as your competent person for H&S, carry the Principal Designer duties on your projects, and prepare your SSIP submission, so the records all reference the same systems instead of contradicting each other. One supplier, one set of paperwork that holds together.
A tender deadline is close. How quickly can you start?
If you've got a deadline inside 30 days, flag it and we'll triage the same day and start work fast. SSIP first-time accreditation in two to four weeks is realistic when we engage early enough. Our consultant achieved CHAS in four weeks for a contractor who'd been stuck six months. The sooner we see what the client is asking for, the better the odds.
Do you only work with large contractors?
No. Much of our construction work is with SMEs: the contractor whose H&S has landed on an office manager, the firm bidding above its usual size, the M&E business that needs accreditation to get onto a framework. Specialist depth at a price that suits a smaller firm is the gap we fill.
We're nationwide. Are you?
Yes. We're based in Altrincham and cover sites across the North West, but we support contractors nationwide. Site visits, audits and inspections are arranged around your programme.
