# DBS Checks, Safeguarding and Working Near Vulnerable People
You can think of DBS as proof you're safe to have around vulnerable people -- but most trades don't legally need the full bells-and-whistles check unless they're regularly around kids or patients.
1. DBS basics -- levels and who decides
A DBS check is a criminal record check done by the Disclosure and Barring Service in England and Wales.
Levels:
- Basic -- shows unspent convictions only. Anyone can request one (including you, as a self-employed tradie).
- Standard -- shows spent and unspent convictions, cautions, reprimands and final warnings, subject to filtering rules.
- Enhanced -- same as Standard plus any relevant police info; can be with or without a barred list check.
- Enhanced + Barred List -- checks if you're on the children's and/or adults' barred lists (banned from "regulated activity").
For trades:
- One-off or occasional jobs in schools/hospitals: often Basic or no formal check; level is up to the site/client's policy
- Regular work around kids/patients (e.g. caretaker-style, in classrooms every week): usually Enhanced, sometimes with barred list if the role is regulated activity
Who decides level: the organisation in charge of the site (school, hospital, care home, prison) decides the level they require, often via their HR/safeguarding policy. If you're through a main contractor, they'll normally tell you what level is needed and organise any Standard/Enhanced checks via their umbrella body.
Important: you cannot request your own Standard or Enhanced check as a one-man band; a registered employer or umbrella body has to do it. You can get a Basic check yourself online.
2. Regulated activity -- when construction roles cross the line
Under the Safeguarding Vulnerable Groups Act 2006, "regulated activity" is work that puts you in close, unsupervised and regular contact with children or vulnerable adults -- things like teaching, caring, supervising, or providing personal care.
Normal construction work: fitting boilers, wiring, re-roofing, refurbs etc. in a school/hospital is not usually regulated activity on its own, because you're not in charge of or caring for children/patients.
You move towards regulated activity if:
- You're in a school or children's centre frequently (often taken as 3+ times in 30 days or overnight stays), and
- You could have unsupervised contact with children
Typical school practice:
- Contractors in school more than 3 times in 30 days during term time often need an Enhanced DBS (no barred list)
- If what you do is somehow regulated activity (rare for trades), it's Enhanced with children's barred list check
- If you only work holidays/out of hours when no kids present, Enhanced is not normally justified -- Basic may suffice
Hospitals, care homes, prisons, children's centres: same idea -- it's about whether you're regularly around, or alone with, vulnerable people, not just the building type. Many sites still policy-require checks for contractors anyway.
Legally: if your role doesn't meet the regulated activity tests, they can't lawfully check barred lists, but they can still ask for Enhanced without barred lists or Standard/Basic if the role qualifies.
3. Criminal records, spent convictions and what shows
Rehabilitation of Offenders Act -- when things become "spent"
The Rehabilitation of Offenders Act 1974 says some convictions become "spent" after a rehabilitation period with no re-offending.
Recent changes mean many sentences up to 4 years, and some over 4 years for less serious crimes, can eventually become spent if you stay clean.
Once spent, for most jobs you don't have to declare them and they don't show on Basic DBS.
For roles needing Standard/Enhanced, some spent convictions can still show unless they are "filtered" under DBS rules.
Filtering -- what disappears from Standard/Enhanced
DBS filtering removes certain old/minor cautions and convictions from Standard and Enhanced certificates.
Broadly (simplified):
- Some old adult cautions are filtered after 6 years if they're for filterable offences and there's nothing serious
- Some adult convictions without custody can be filtered after 11 years if they're for filterable offences and there's only one
- Serious violent/sexual/terror offences are never filtered
So that pub scuffle caution from 20 years ago may not show on an Enhanced check, depending on the details.
What tradespeople worry about
Basic -- only unspent convictions. Recent drink-driving, current suspended sentence, recent theft: yes. Old, spent stuff: no.
Standard / Enhanced -- show unspent and some spent convictions/cautions, subject to filtering. Police can include relevant local information in Enhanced.
Common worries:
- Drink driving / driving offences -- usually not bars to school work unless pattern suggests ongoing risk
- Old assault (pub fight) -- if minor and long ago, may be filtered or treated as low risk depending on role
- Drug possession -- context matters; serious supply or recent dependence is more of an issue
- Theft -- more relevant if work involves unsupervised access to property/valuables
Even with unspent convictions, you are not automatically banned from working in schools/hospitals -- the key is whether you're on a barred list and what the employer's risk assessment says.
4. Practical site reality -- you, DBS and awkward asks
You get called to a school and they ask for DBS
If you don't have what they want:
- You can refuse the job -- your choice
- You can ask if they'll accept a Basic DBS (which you can get online yourself), or you being under "reasonable supervision" on site instead of needing a check
Schools guidance often says:
- If contractors are not in regulated activity but have regular contact, Enhanced (no barred list) is typical
- If they're one-off or short-term, they may rely on supervision and sign-in controls instead of checks
Emergency repairs
There's scope for schools/hospitals to treat emergencies differently -- they may let you in under tight supervision and restricted access rather than waiting weeks for a DBS. Legally, they must still safeguard kids/patients, so expect chaperoning and no wandering.
Who pays and how long it takes
Often the employer or main contractor pays for Standard/Enhanced checks. Self-employed can end up paying themselves via umbrella bodies.
Typical turnaround:
- Basic -- often a few days
- Standard/Enhanced -- can be 2-8 weeks, sometimes faster, sometimes slower depending on police forces
How long is a DBS "valid"?
Technically, a DBS certificate has no expiry date -- it's a snapshot on the day it was issued. In reality, most schools/hospitals/main contractors want a certificate less than 3 years old, some insist on 1-2 years.
DBS Update Service -- is it worth it?
The Update Service lets employers check online if your Standard/Enhanced DBS is still up to date, instead of doing a new one each time.
- It's £13/year and you must register within 30 days of your DBS certificate issue date
- If you regularly work on sensitive sites, subscribing can save hassle and repeated checks
5. Subbies, main contractors and self-employed
If you're under a main contractor on a school refurb, it's normally their responsibility to decide the level of check, get the DBS done through their umbrella provider, and hold and verify the records.
As a self-employed sole trader, you can:
- Apply for a Basic DBS directly
- Get Standard/Enhanced only via a registered body (umbrella company, trade association, agency)
If you've got a past you're worried about: be honest with the umbrella/body up front -- they've seen it all. They can advise how likely certain convictions are to be a problem for the roles you're going for.
6. Do I need a DBS for this job? -- Quick flowchart
Private home
Are you being hired specifically to care for children or vulnerable adults (not just do building work)?
- Yes -- this is outside normal trade work; client may legitimately ask for Enhanced + barred list
- No -- no legal DBS requirement. Client might still ask for a Basic check as reassurance.
School / nursery / children's centre
Will children be on site while you're working?
- No (holidays/evenings only) -- legally unlikely to be regulated activity. School may still policy-require Basic or Enhanced (no barred list), or rely on sign-in + supervision instead.
- Yes -- how often?
One-off or just a few times:
- Will you be under constant, reasonable supervision by school staff and not left alone with kids?
- Yes -- school can rely on supervision and may not insist on DBS
- No / not sure -- school likely to demand at least Basic or Enhanced (no barred list)
Regular (3+ times in 30 days) or long project:
- Your role is construction/maintenance only, not caring or teaching?
- Yes -- usually Enhanced DBS (no children's barred list) is appropriate
- No, you're also supervising/teaching kids -- now you're into regulated activity; Enhanced with children's barred list likely needed
Hospital / GP / clinic / care home
Will patients/residents be present while you work?
- No (e.g. plant room out of hours) -- not regulated activity. Organisation may still policy-require Basic or Enhanced.
- Yes -- how often and how close?
- One-off / short-term, always with staff around -- may accept no DBS or Basic only
- Regularly on wards / near patients, possibly alone at times -- Enhanced DBS likely required, sometimes with adults' barred list if role meets regulated activity tests
Prison / probation premises
- Regular work inside secure areas / near prisoners -- expect Enhanced DBS, sometimes with barred list
- One-off supervised job (e.g. plant room) -- may accept Basic or rely on security vetting
Remember:
- You can't request your own Standard/Enhanced as a sole trader -- a registered employer or umbrella body must do it
- You can buy your own Basic DBS online
- Supervision option: if you don't have DBS and it's a one-off or emergency, ask if they'll let you work under reasonable supervision
- DBS Update Service: if you're on schools/hospitals regularly, get one Enhanced check then join the Update Service (£13/year)
7. Safeguarding -- your duty when something feels wrong
DBS checks are about you; safeguarding is about what you see.
As a tradie in homes, schools, care homes, you may spot things others miss:
- Injuries that don't match the story
- Kids or vulnerable adults clearly neglected or afraid
- Signs of domestic abuse, substance abuse, exploitation
You're not a social worker, but you are a set of eyes and ears.
If you're worried:
- If a child is in immediate danger -- call 999 or the NSPCC helpline 0808 800 5000 straight away
- If it's not immediate but feels off:
- In a school/hospital/care home -- talk to the safeguarding lead or manager on site
- In a domestic home -- ring the NSPCC helpline for advice, or contact your local authority safeguarding team (they all have a duty line)
NSPCC are happy to talk through "I've seen X, I'm not sure if it's bad enough" -- they'll help you decide the next step.
8. Scotland and Northern Ireland
Scotland -- Disclosure Scotland runs checks; for working with vulnerable groups they have the PVG (Protecting Vulnerable Groups) scheme. Contact: 0300 020 0040.
Northern Ireland -- checks go through AccessNI with their own levels and rules.
If you're working north of the border or in NI, the names and forms change -- don't assume the England/Wales DBS rules apply.
What to do next
- If you've been asked for a DBS and don't have one: use the flowchart in section 6 to work out what level you actually need, then talk to the site manager or your main contractor
- If you work on schools/hospitals regularly: get one Enhanced check done and join the DBS Update Service (£13/year) -- saves repeated checks
- If you're worried about your record: talk to the umbrella body or organisation doing the check before you panic. Filtering means many old/minor things don't show.
- If you've seen something concerning on a job: talk to the safeguarding lead on site, or call the NSPCC helpline for advice
