The verdict in three sentences
With 2,300 operatives across some twenty sites, a London construction group can no longer prove safety competence with binders and photocopied certificates. A custom certification platform (light videos, quizzes, QR competence cards linked to CSCS status, expiry alerts) costs 60,000 to 120,000 GBP and 1,500 to 3,000 GBP a month, delivered in 4 months. It pays back mostly through avoided site stoppages and tenders won with demanding principal contractors and clients.
Why clients demand proof
Major clients in London (public bodies, infrastructure owners, developers, tier 1 contractors) now require a verifiable training register under CDM 2015: site induction, working at height, scaffolding, lifting operations, electrical safety, plant operation. A site check where an operative cannot show valid competence means a stand-down and sometimes a contractual penalty. HR must answer within minutes the question "who is competent for what, until when, on this site?".
| Competence | Typical validity | Operatives concerned (of 2,300) | Classroom cost per operative |
|---|---|---|---|
| CSCS card and site induction | 5 years card, induction per site | 2,300 | 150 to 250 GBP |
| Working at height and harness | 3 years | 900 | 180 to 300 GBP |
| Scaffolding (CISRS) | 5 years | 260 | 900 to 1,600 GBP |
| Slinger and signaller (CPCS or NPORS) | 5 years | 180 | 600 to 1,000 GBP |
| Electrical safety awareness | 3 years | 220 | 200 to 350 GBP |
| Plant operation (CPCS) | 5 years | 140 | 1,200 to 2,500 GBP |
What the platform includes and what it costs
The platform does not replace hands-on training, it records it and handles the theory part. Videos are compressed to run on site Wi-Fi or 4G on basic phones, with subtitles in the main languages spoken on London sites (Romanian, Polish, Portuguese). 2026 estimate for a London agency; a French-speaking nearshore team can deliver the same scope 35 to 45 % cheaper.
| Module | Content | Estimated cost |
|---|---|---|
| Operative and site register | HR import, assignments, subcontractors | 8,000 to 15,000 GBP |
| Light video modules and quizzes | Low-bandwidth player, 10-question quiz, 80 % pass mark | 12,000 to 25,000 GBP |
| QR competence cards and CSCS check | Printable card, scan without login, CSCS status lookup | 9,000 to 18,000 GBP |
| Expiry alerts | SMS and email at D-60, D-30, D-7 to site managers | 5,000 to 10,000 GBP |
| Dashboards and client exports | Compliance rate per site, signed PDF | 9,000 to 18,000 GBP |
| External training providers | Certificate upload, validation | 6,000 to 12,000 GBP |
| Monthly running cost | Hosting, SMS, maintenance, support | 1,500 to 3,000 GBP |
By comparison, an international LMS billed per user often costs 3 to 6 GBP per user per month, 7,000 to 14,000 GBP a month for 2,300 operatives, without native QR cards or expiring competences.
Mini case study
Rachel, HR director of a London construction group, manages 2,300 operatives and 600 agency workers a year. Today, the general safety refresher runs in classrooms by half day: 2,300 people at 90 GBP of training and 110 GBP of half-day wages, 460,000 GBP a year. With theory delivered by phone video (45 minutes) and a short practical sign-off, the cost falls to about 190,000 GBP. Add 3 avoided stand-downs a year at 15,000 GBP each. For a 95,000 GBP platform at 2,500 GBP a month, net first-year gain exceeds 190,000 GBP.

Can operatives without smartphones complete modules?
Yes, shared tablets in welfare cabins or site offices are enough, at 200 to 350 GBP per tablet. The QR card stays readable by any site manager's phone.
Does the platform work without signal on site?
The card scan shows competences cached at last sync, with an offline mode added for 6,000 to 10,000 GBP. Quizzes sync as soon as connection returns.
Is operative data protected?
Yes, UK GDPR applies and the platform needs a data protection impact assessment. The QR card shows only competence data, no sensitive personal information.
Can subcontractors be included?
Yes, each subcontractor gets access to declare its operatives and upload their certificates. That usually covers 20 to 35 % of the workforce on a large site.
How is the project paid?
A 3-stage schedule (40 %, 40 %, 20 % at acceptance) is common. The monthly subscription is paid by bank transfer or card.
