A man turns up to site on Monday morning. He’s done the job for fifteen years. The gateman scans his card, the screen flashes red, and he’s sent home. His card expired three weeks ago and nobody told him, because nobody was watching.
That’s a lost day for him and a hole in your programme. The frustrating part is that the expiry date was never a secret. It was printed on the card. You just didn’t have it anywhere you’d look in time.
Let me explain what that card is, in case you’ve never had to think about it. Most people on a UK building site carry a CSCS card — the Construction Skills Certification Scheme. It’s a plastic card that shows the holder has passed a basic health and safety test and holds the right qualification for the job they do. It isn’t the law. No statute says a worker must have one. But nearly every main contractor — the firm running the site — refuses to let anyone through the gate without a valid one. So in practice it may as well be the law, because without it your people don’t work.
Here’s the catch. A card is valid for a while, and then it isn’t. Most last five years. To get a new one, the holder has to sit the health and safety test again — it’s called the CITB Health, Safety and Environment test — and reapply. That takes time. If you find out on the Monday, you’re already too late.
The record is a drawer, or a spreadsheet nobody opens
Ask a mid-market firm where its card records live and you tend to get one of two answers. Either there’s a drawer of photocopies and phone photos, or there’s a spreadsheet somebody built a few years ago. Both have the same flaw. They tell you the card exists. They don’t tell you it’s about to stop existing.
A photo of a card is a snapshot of a fact that changes. The day you took it, the card was valid. That says nothing about next Tuesday. The expiry date is sitting right there in the picture, and no one is counting down to it.
And it isn’t only CSCS cards. A site manager needs an SMSTS certificate — the Site Management Safety Training Scheme, a five-day safety course that itself runs out after five years. Your first aiders hold a certificate that lasts three. Plant operators carry their own tickets for the machines they’re cleared to drive. Subcontractors have insurances with renewal dates. Every one of those is a date that, when it slips past unnoticed, stops someone working or leaves you exposed.
The churn is getting worse, not better
This used to be quieter, because a lot of older hands held cards under what the industry called grandfather rights — cards granted years ago on the strength of experience rather than a current qualification. Those are gone. The scheme stopped renewing them, and the last of them expired at the end of 2024. From the start of 2025, a card has to be backed by a real qualification. That pushed a wave of experienced people into re-testing and re-applying.
Then, from 2026, the entry-level Labourer card — the green one most new starters carry — had its first-issue length cut from five years to two. More renewals, sooner, for the very people who move between firms most often. The number of expiry dates you’re quietly responsible for is going up, and the tool most firms use to track them is still a spreadsheet nobody has been asked to open.
Why the spreadsheet loses
A spreadsheet doesn’t fail because it’s badly made. It fails because a date three months away isn’t anybody’s job today. The reminder has to come from a person deciding to check, and people check when there’s a crisis, not before one. So the sheet is accurate right up until the morning it matters — when someone’s standing at the gate and the answer arrives too late to be any use.
The fix isn’t a bigger spreadsheet, and it isn’t a ten-part HR platform you’ll use one corner of. It’s a small, plain register that knows two things: who your people are, and when each of their cards and certificates runs out. Something that emails whoever runs the office when a card is sixty days from expiry — while there’s still time to book the test. Not a report you have to remember to run. A nudge that arrives on its own.
That’s the whole job. It’s the sort of thing purpose-built software does well, precisely because it’s narrow. It watches the dates so nobody has to remember to.
Where this doesn’t apply
If you run a handful of people who’ve been with you for years and renew like clockwork, you don’t need any of this. A wall calendar will do. The same holds if you work mostly on your own sites, where you set the access rules and a lapsed card is a quiet word rather than a locked gate. This problem bites when you’ve got dozens of people, a steady churn of subcontractors, and main contractors who turn folk away without a second thought. If that isn’t you, keep your money.
But if you felt a small lurch reading this — because you genuinely couldn’t say whose card expires next month — that’s worth fixing before the gate fixes it for you.
