DBS checks explained — basic, standard and enhanced

DBS checks for employers — the full picture

Almost every safer recruitment conversation starts with the DBS check, and for good reason: it is the only pre-employment check that reaches into police records. But it is also the check employers most often misunderstand — over-requesting levels the role does not qualify for, treating a certificate as if it never goes out of date, or assuming that a clean enhanced check means the candidate is safe to employ. This guide covers what each level actually does, and where its limits are.

Choosing the right level for the role

Start from the role, not from the level you would like. A basic check is available for any position and shows unspent convictions and conditional cautions — for most roles outside regulated sectors, it is the only level you can lawfully obtain. A standard check is reserved for roles listed in the exceptions to the Rehabilitation of Offenders Act, such as certain legal, financial and security positions, and adds spent convictions and cautions subject to filtering. An enhanced check is for roles such as working with children or vulnerable adults, teaching and healthcare, and adds any information held by local police that a chief officer reasonably believes is relevant. Where the role is in regulated activity — the legal definition covering close, regular work with children or vulnerable adults — the enhanced check can also include the children's barred list, the adults' barred list, or both. If you are unsure whether a role is eligible, the DBS publishes eligibility guidance on gov.uk; your Registered Body or umbrella body can also advise.

Barred lists — the part of the enhanced check that matters most

The barred lists are registers of people the DBS has decided are unsuitable to work with children or with vulnerable adults. A barred list check is not an optional extra for cautious employers: it is only available where the role is genuinely in regulated activity, and where it is available it is essential — knowingly employing a barred person in regulated activity is a criminal offence for both the individual and the employer. This is why schools, nurseries, care providers and healthcare employers treat the enhanced-with-barred-list check as the baseline, alongside the rest of their safer recruitment checks.

Why "is this DBS still valid?" is the wrong question

A DBS certificate never officially expires, because it never claimed to cover the future in the first place. It is an extract of what was recorded about the applicant on the date of issue. A certificate issued three years ago is exactly as accurate about that date as it was on day one — and says nothing about the three years since. So the real question is not "is it valid?" but "is it recent enough for this role, and what is our policy for rechecking?" Regulated employers are expected to be able to answer that in writing. The Update Service makes the answer much easier for standard and enhanced certificates: with the candidate's consent, a free online status check tells you whether a new certificate would say anything different. If the candidate is not on the Update Service, a new application is the only way to refresh the information.

What a DBS check will never show you

Here is the uncomfortable truth at the centre of safer recruitment: most of the reasons a candidate is unsuitable never reach a police record. A care worker dismissed for neglect, a teaching assistant who resigned during a safeguarding investigation, a nurse with a pattern of unexplained absences, a manager with a string of misconduct warnings — none of this appears on any level of DBS check unless it resulted in police involvement. The only pre-employment check that can surface it is a written reference from the previous employer, asking structured questions about conduct, disciplinary history and suitability to work with vulnerable people.

That is why the safer recruitment frameworks demand both. Keeping Children Safe in Education requires schools to obtain references and scrutinise them alongside the DBS and other checks — see our school pre-employment checks guide for the full list. For care providers, CQC's reference checking requirements under Regulation 19 sit alongside the DBS requirement, and inspectors sample staff files for both — the complete set is covered in our care worker pre-employment checks and healthcare pre-employment checks guides. NHS Employment Check Standards and GLAA licensing standards take the same both-not-either position.

Running DBS and references in parallel

The practical mistake employers make is running checks in sequence: apply for the DBS, wait, then start chasing referees by phone once the certificate lands. Since DBS turnaround is outside your control, the efficient pattern is to launch references the moment the offer is made. With RefAssure's reference checking software, you add the candidate, the platform captures their GDPR consent with a digital signature, referees receive secure single-use links, and automated email and SMS chasing runs over around 12 days without anyone in HR touching it. Referees either complete a structured online form or simply reply by email — both are captured — and you get a structured PDF report with a full audit trail for the staff file. By the time the DBS certificate arrives, the references are usually already done. You can see the whole flow on our how it works page, or try a reference template to see the questions referees are asked.

Pricing is pay-as-you-go: credits from 99p per reference, no subscription and no contract, and credits never expire — see pricing for the credit bundles, or the FAQs for the common questions. For sector-specific guidance, start with reference checking for care agencies, education and safeguarding or healthcare.
