About Assured Contractors
Contractor assurance that costs contractors nothing.
Assured Contractors is contractor assurance software built in the UK by Res Digital. It keeps contractor prequalification, every worker's cards, permits, bookings, the site gate, visitors and muster on one record. Clients pay a subscription; the contractors who work for them join free, on every plan.
We built it because the industry's paperwork checks companies, while the risk on a site turns up every morning as a person: a particular operative, with a particular card, on a particular day. And because the contractors asked to prove all of this shouldn't have to pay for the privilege.
- Built by Res Digital in the UK
- Free for contractors, always
- Not an accreditation scheme

Why we built it
What problem does Assured Contractors solve?
Schemes assess companies. SSIP, PAS 91 and Common Assessment Standard schemes check whether a company had the right systems when it was assessed. That's useful, and many clients rightly ask for it.
The risk is the person at the gate. Accidents happen to people and because of what people do: the operative whose card lapsed last week, the plant operator nobody checked, the crane booked twice, the visitor who isn't on the roll call. A company certificate can't tell you about any of them.
Contractors pay again and again. The same insurance certificate and policies go to every client, often through a different portal or scheme each time, and the time and the fees land on the contractor.
Duplicated prequalification was estimated to cost the industry up to £1bn a year, with around 180,000 specialist contractors producing over two million pieces of paper. Source: Construction Enquirer: common prequalification launches to save £1bn
A contractor keeps one profile, free, and uploads each document once. Every client it works for sees the current version and reviews it on its own terms, then carries the same record through to the gate.
What we built
One record, from the first document to the last person out.
Most sites run contractor safety across a portal, a spreadsheet, a permit pad, a sign-in book and an inbox. Assured Contractors puts the four stages on one record, so each one uses what the stage before it already knows.
- 01PrequalifyCompany documents, insurance, accreditation certificates and Companies House status, against your requirements.
- 02CompetenceEvery worker and every card, with expiry reminders and readiness for each site.
- 03Plan the workJobs, subcontractor chains, permits to work, and crane, hoist and delivery bookings.
- 04The gateA readiness check on arrival, live attendance, visitors from the kiosk and the muster roll call.
Our principles
What we won't compromise on.
Contractors never pay
No joining fee, no annual fee, no fee per client or per worker, on any client's plan. The client that runs the site pays one subscription, so there's no Assured Contractors cost for a contractor to recover in its prices.
Every decision has its reasons
A status is never just a colour: “Why?” lists every reason. Gate decisions record why. Overrides need a reason and an end date, suspensions need a reason, and every action goes in the audit log.
One record, prequalification to the gate
The company, its people, their cards, the job, the permit, the booking and the gate check all read from the same record, so a change in one place shows up everywhere it matters.
Your data is yours
Lists and the audit log export to CSV; permits, registers and worker records export to PDF. You shouldn't have to ask us for your own records.
Easy enough to need no training
A contractor joins with their client's code and a four-field form, and is connected straight away. Everything runs in a browser on phones and tablets as well as computers: gate mode on the gatehouse tablet, the visitor kiosk on a visitor's own phone.
Made for UK sites
Companies House, DVSA MOT history and DVLA tax built in; CSCS, CPCS, NPORS, IPAF and ECS cards; RIDDOR fields on incidents; a COSHH register; hot work, confined space and work at height permits.
Being clear
What isn't Assured Contractors?
Knowing what a product doesn't do is as useful as knowing what it does. Here's where we've drawn the lines, and why.
Not an SSIP scheme
We don't assess or certify companies, and we don't issue SSIP, PAS 91 or Common Assessment Standard certificates. That's deliberate: a scheme is an independent assessment the contractor pays for. We're the client's own system, and we stay free for contractors. If you require SSIP, contractors store the certificate here with its expiry date.
Not a card-checking service
Workers' cards are recorded with their numbers, expiry dates and photos, and your own reviewers approve them. Live checks against the CSCS Smart Check service aren't built in.
Not hardware
No turnstiles or biometric readers to buy. Assured Contractors is software that runs on the computers, tablets and phones you already have.
Not a marketplace
We don't sell tender leads to contractors or rank contractors for clients. Each client decides who it works for and what it requires.

The name
Why “Assured Contractors”?
Because that's the outcome a client wants: contractors it can be assured of, checked against its own requirements, in date, and ready for the site today.
The address says who it's for. A client sends its contractors a link like assured.contractors/join/NBG-7K3M; they join free in a couple of minutes and are connected straight away. When the next client sends its code, the contractor enters it and the same profile serves both.
Who pays what
- ClientsOne subscription for their workspace, after a 14-day free trial. See pricing
