For principal contractors & site owners
Your contractors join free. Your sites run on one record.
Assured Contractors gives principal contractors and site owners one workspace to prequalify contractors, check every worker's cards, plan permits and bookings, and decide who comes through the gate. Your contractors join free, so there's no Assured Contractors fee for them to build into their price.
You pay one subscription and set what each kind of work requires. Send your contractors your company code or invite link; they join free and are connected to you straight away, then keep their own documents current. Your reviewers approve on your terms, and every decision lands in your own audit trail.
- 14-day free trial, no card needed
- Contractors join free, on every plan
- A “Why?” behind every status

Onboarding your supply chain
How do your contractors join?
No onboarding project and no fee to negotiate. Three steps, and the contractor's part takes a couple of minutes.
Send your company code
Your code (it looks like NBG-7K3M) and invite link are on your Contractors page. Send either to your contractors by email, by text or with the order.
They join free, connected to you
A new contractor enters the code with four fields (name, work email, company name and a password) and is connected to you straight away, with no approval step. One already on Assured Contractors for another client enters your code on its dashboard and brings the profile it already keeps.
Review on your terms
Your requirement set says what's needed. Anything missing shows under “Why?”, and you send a document request instead of chasing by email.
Already have a contractor's own code (AC-XXXX-XXXX)? Enter it under Add company to connect them. Or add the company yourself and send an invitation; they still join free.
Who pays
You pay one subscription. Your contractors pay nothing.
Why does that matter to you?
When a portal charges contractors, the cost has to come from somewhere, and their rates are the obvious place. Assured Contractors doesn't charge contractors at all, so there's no Assured Contractors subscription for them to recover in their price for your work.
It also takes the argument out of onboarding. Asking a six-person firm to buy another membership slows everything down; sending them a free code doesn't.
Your workspace: plans from £149 a month excluding VAT, after a 14-day free trial with no card needed. See plans and what's included

Sound familiar?
What this usually looks like today.
The approved list is out of date the day you print it
The insurance renewed in March still shows last year's certificate. A supplier was struck off at Companies House over the summer and nobody noticed.
Your checks stop at the company
An SSIP certificate tells you a firm passed an assessment. It doesn't tell you whether the slinger/signaller arriving on Monday holds an in-date CPCS or NPORS card.
Every portal fee ends up in someone's price
Ask a small firm to pay for yet another membership and they drag their feet, or the cost finds its way into their rates for your work.
Five systems, and nobody knows who's on site
Prequalification in one portal, permits on carbon pads, a sign-in book at the gate and crane bookings in a shared calendar. When the alarm goes, the roll call is a guess.
What changes
What changes with Assured Contractors?
Nothing for contractors to pass on
Contractors never pay to join or connect, on any plan, so onboarding is your code sent by email and there's no Assured Contractors fee in their price.
Requirements you set
Requirement sets say which documents, insurance and cards each kind of work and risk tier needs, so a low-risk supplier isn't buried in high-hazard checks.
Contractor prequalificationA status that explains itself
Every contractor is Ready, Action required or Blocked, and “Why?” lists each reason: the EL certificate that expired, the policy that was never sent.
Contractor prequalificationCompanies House, watched for you
Look a company up by name or number when you add it. Its status is linked and monitored, so a dissolved supplier shows up before the next order.
Contractor prequalificationPeople, not just paperwork
Each worker's CSCS, CPCS, NPORS, IPAF or ECS card with number, expiry and photos, checked against the job, the booking role and the site.
Worker competenceThe gate uses the same record
Gate staff search a name and see a live readiness check, then allow, refuse or refer with a reason. Live attendance feeds the muster roll call.
Site access & musterHow it plays out
A new package, a new subcontractor, one week
A principal contractor starts a mechanical fit-out package on a live site.
The package manager emails Hargreaves Mechanical the company code. They already use Assured Contractors for another client, so they enter it on their dashboard and are connected within minutes. Their profile (insurance, policies, SSIP certificate) is already there, and it costs them nothing.
Status: Action required. “Why?” shows one reason: your requirement set asks for £10m employer's liability and their certificate says £5m. You send a document request.
The new certificate arrives in your review queue. Your reviewer accepts it and Hargreaves turns Ready.
Six fitters arrive. Five are ready at the gate; one has an expired CSCS card and is referred to the site manager, with the reason recorded.
A hot work permit for brazing in the plant room is requested, assessed and issued with its checklist, then closed at the end of the shift.
Illustrative example. Company names are invented.

Hot work, confined space, work at height and more, from request to close.

Cranes, hoists and deliveries that check the operator's card and refuse double-bookings.
See how it worksVisitor sign-in kiosk
A kiosk per site, so visitors are on the same muster list as everyone else.
See how it worksDo our contractors have to pay?
No, on any plan. Contractors join free with your company code or invite link, are connected to you straight away, and keep one profile that every client they work for can see. There's no joining, annual, per-client or per-worker fee for them.
You pay one subscription for your workspace, so there's no Assured Contractors fee for your contractors to recover in their prices.
How do we get our contractors connected?
Send your contractors your company code or invite link; they join free and are connected to you straight away. You'll find both on your Contractors page.
A new contractor joins with the code and a four-field form in a couple of minutes, with no approval step. One that already uses Assured Contractors for another client enters your code on its dashboard, and you see the profile it already keeps. You can also add a contractor by entering its own contractor code.
How much does it cost us, and is there a trial?
Plans start at £149 a month (Starter), with Professional at £449 and Enterprise at £1,195, excluding VAT. Every new workspace gets a 14-day free trial of Professional with no card needed. The pricing page sets out what each plan includes.
What does a client workspace include?
Contractor prequalification, worker competency cards, vehicles and equipment, jobs with subcontractor chains, permits to work, crane, hoist and delivery bookings, gate check-in and live attendance, emergency muster, a visitor kiosk, incidents, observations, inspections, a COSHH register and H&S policies. It all works from one record of companies, people and sites.
Can we keep requiring SSIP, CHAS or Constructionline?
Yes. Assured Contractors isn't an accreditation scheme and doesn't issue certificates. If your requirement set asks for SSIP, contractors upload their certificate with its expiry date and it's tracked like any other document, alongside the things a scheme doesn't cover: each worker's cards, permits, bookings and the gate.
What do we see if a contractor also works for other clients?
You see the same company profile they keep for everyone: documents, insurance, vehicles and the workers they assign to you. You review it on your own terms, and your decisions, notes and audit trail stay in your workspace.
Can it carry our branding?
Yes, on the Enterprise plan. A client workspace can use its own logo, colours and product name, so your contractors see your brand on every screen.
