DBS Checks in Construction: When You Need One and Which Level

‍‌​‌​‌​​​​‌‌‌​‌​‌​​‌​‌‌​‌‌​​‌​‌​‌‍SiteKiln gives you plain-English information, not legal advice or specialist safeguarding guidance. If you need advice specific to your situation, check the latest DBS and government guidance.

7.9.1 The short version

DBS checks are about who you are, not how good you are on the tools. They're there to stop people who are barred from working with children or vulnerable adults getting near them, under the Safeguarding Vulnerable Groups Act 2006.

On most normal sites you won't need more than, maybe, a basic check if the client insists. The game changes when you're in live schools, hospitals, care settings or certain government/MOD sites -- then enhanced DBS checks (sometimes with barred-list checks) are standard for anyone on site regularly while kids or vulnerable adults are around.

7.9.2 Why it matters

If you work in those environments and your lads haven't got the right level of DBS, you simply won't get the job or through the gate. Schools, NHS trusts and MOD establishments are under their own safeguarding duties and will not budge.

It also cuts both ways. If you send someone with a dodgy history into "regulated activity" and haven't done proper checks, you're taking on serious safeguarding and reputational risk, and the client will remember your name for all the wrong reasons.

7.9.3 The legal backdrop -- regulated activity and the DBS

The Safeguarding Vulnerable Groups Act 2006 set up the vetting and barring regime and, later, the Disclosure and Barring Service (DBS).

Key ideas:

• Regulated activity is defined in Schedule 4 -- close, frequent or overnight work with children or vulnerable adults (teaching, supervising, caring, etc.).
• People barred from this work are listed by the DBS; it's a criminal offence for them to do regulated activity, or for you to knowingly employ them to do it.
• "Period condition": if an activity happens on more than 2 days in 30, or overnight, it usually counts as regulated activity.

Most construction workers aren't directly doing regulated activity (they're not teachers or carers), but the setting and frequency mean you often still need at least an enhanced DBS check if you're on site around children or vulnerable adults regularly.

7.9.4 Schools, hospitals, care and MOD -- what checks they expect

In practice, for contractors:

Schools

• If a worker is on school premises three or more times in 30 days during term, while children are present, they'll usually need an enhanced DBS check.
• If there's any chance of unsupervised work around pupils, that may be enhanced with children's barred-list check.
• Holiday-only work (no pupils on site) may only need a basic DBS or none at all, depending on the school's risk assessment.

Hospitals and care settings

• If your lads are working in live wards or areas with patient access, expect at least enhanced checks, sometimes with adult barred-list depending on duties.
• If they're segregated (plant rooms, compounds, out-of-hours) a basic check may be all that's requested.

MOD / security-sensitive sites

• Often want DBS as part of a wider vetting package (SC / CTC etc.) -- level depends on the role and access, but assume at least basic or standard as a baseline.

Schools and hospitals are told to risk-assess contractors: if not in regulated activity but regularly around children, they still often require enhanced (without barred-list), plus strict supervision and segregation.

7.9.5 Quick DBS health check for your business

You're in a sensible spot if:

When you tender for schools, hospitals or care/MOD work, you can state clearly what level of DBS your people hold (basic/standard/enhanced) and how often you re-check.

You understand that regular presence on a school site during term pushes you into enhanced-check territory, even if you're "just the builder".

You're not leaving it to the last minute; you've got a process/umbrella body lined up so you can get checks turned around quickly when a job lands.

If any of that is a "no", that's something to sort before you price your next school or hospital job, not after the client asks for DBS numbers at pre-start.

7.9.6 What to do next

• Before pricing school, hospital or care/MOD work, check what level of DBS the client requires and build time into your programme for processing.
• Set up a relationship with an umbrella body so you can get DBS checks turned around quickly when a job lands.
• Understand that regular presence on a school site during term pushes you into enhanced-check territory, even if you are "just the builder".
• Keep a register of which workers hold which DBS level and when checks were last done.
