Care Worker Pre-Employment Checks: Cross-Check Guide

This article is for information only and is not legal advice. Regulatory references are accurate at the date of publication and cover England and Wales unless stated. Consult a qualified professional before making a hiring decision.

Care worker pre-employment checks work when each document is compared with another document or an official source, not when each is simply collected. A care file for a home care or domiciliary role should answer four questions: is this the person named on every document, is the criminal record check the right level for the duties, do the qualifications belong to this person, and does this person have the right to do the work. This guide sets out which field is compared with which, what a mismatch looks like, and what the reviewer does next.

What are care worker pre-employment checks?

Pre-employment checks for a care worker are the identity, criminal record, qualification and right-to-work controls an employer completes before the first shift, and they only protect you if the results agree with each other. Collecting four documents is the easy part. The control is the comparison: the surname on the passport against the surname on the DBS certificate, the date of birth on both against the training certificates, the start date against every expiry date.

Home care raises the stakes because the worker is alone in a client's home, often with no supervisor nearby. A file that is merely "complete" can still contain an applicant whose certificate was issued for a different job role, in a former name, or whose permission to work ends in six weeks. The sections below build the file around those comparisons.

The cross-check map: which field is compared with which

A usable care file contains at least eight cross-document comparisons, and each one needs a named outcome and a named next step. The table is the core of the process; the sections after it explain the registers behind each line.

The rest of this guide explains where each comparison comes from.

How do you check the criminal record level for a home care role?

The DBS check level is set by the duties, not by the employer's preference: personal care for an adult qualifies for an enhanced check with the Adults' Barred List, wherever it takes place. The GOV.UK leaflet on DBS checks for adult social care roles lists personal care as physically assisting an adult with eating, drinking, going to the toilet, washing or dressing, and states that it counts "irrespective of whether this happens in the adult's own home, a hospital, a care home". Domiciliary workers who do not give personal care may qualify for an enhanced check without the barred list if they meet the frequency test: more than three days in a 30-day period, an overnight stay between 2am and 6am, or at least weekly on an ongoing basis.

The cross-check here is between two documents you control: the job description and the position stated on the certificate. A mismatch is common when an agency reuses a certificate obtained for a care home role to place the same person in a client's home with personal care duties. The certificate then shows a lower level than the role needs. The reviewer's next step is a fresh application at the right level.

What the certificate proves matters. It records the information held at the date it was issued. It does not prove the certificate in front of you is genuine, and it says nothing about events after that date. Compare it with the application form, and where your policy allows, confirm its details with the applicant on a call rather than relying on a photocopy.

For forged certificates specifically, read how fake criminal record certificates are detected.

How do you cross-check qualifications and training records?

A qualification is verified by matching the name, the awarding body and the dates to the person and to the rest of the file, then confirming the award with the issuer when the role depends on it. For care roles the questions differ by document. A nursing registration is confirmed against the regulator's public register, as covered in our guide to healthcare credential verification. A training certificate from a provider is confirmed with that provider.

Typical mismatches in care files:

• The name on the certificate is a maiden or previous name and no link document is on file.
• The course dates overlap a period the applicant says they were abroad or in another job.
• The certificate has no provider contact, no unique reference, or a reference format that the provider does not use.
• The award is older than the experience claimed on the CV, or the claimed level does not exist under that title.

None of these proves dishonesty. Each is a reason to ask one question and write down the answer. The reviewer should keep the confirmation email or call note in the file, because "I checked" without a record is weak evidence in an inspection.

How do you run a right-to-work check on a care applicant?

An employer has a statutory excuse against a civil penalty only if it checks right to work before employment starts, in one of three ways, and records the date of the check. GOV.UK's guidance on checking a job applicant's right to work describes an online check using the applicant's share code, a manual check of original documents with the applicant present, or an identity service provider using identity document validation technology for British and Irish citizens. In a manual check you confirm the documents are genuine, belong to the applicant and match across documents, then keep copies and record the date. The guidance notes that biometric residence cards and permits are no longer accepted as manual-check documents.

The cross-checks are:

1. Name and date of birth on the right-to-work result against the passport and the DBS certificate.
2. Photograph on the online result or document against the person in front of you or on the video call.
3. Expiry date and work conditions against the start date, the contract hours and any restriction on the type of work.
4. Follow-up date diarised for time-limited permission, so the check is repeated before it lapses.

A share-code result shows the status held by the Home Office at the time of the check. It does not show what the person's DBS or qualification files say, which is why the three streams must be reconciled by a person or a system, not assumed to agree.

What do care applicants and recruiters actually ask?

The questions that recur on recruiter and carer forums are practical: whether an old DBS can be reused, whether a name change matters, and what happens when documents disagree. People often ask whether a certificate from a previous care employer can be accepted for a new client. It can only be accepted if the level and workforce match the new duties and your policy allows reuse; the certificate itself does not travel with a guarantee. Applicants also ask whether they will be rejected because the name on their qualification differs from their passport. They should not be, provided a link document explains the change and the file records it.

Another frequent question from agency staff is how to avoid delaying a start when one document is missing. The safe answer is to hold unsupervised work until the check at the right level is back, and to use that period for supervised induction only where your regulator's rules allow it. Do not start on the assumption that a clean result will arrive.

How should the file be organised and retained?

A care file is reviewable when every comparison above has a recorded outcome, a reviewer and a date. Keep one record per applicant listing the document, the field compared, the result (agree, explained difference, unresolved) and the person who closed it. Handle criminal record data as special data under UK data protection law: restrict access, keep only what your policy justifies, and delete on schedule. The Information Commissioner's Office publishes guidance on employment practices and data protection that applies to this file.

Where volumes are high, a document validation tool can run the comparisons for you. CheckFile's HR document verification compares names, dates and expiry fields across the documents in an applicant file and flags the differences for a reviewer. It does not decide who is hired and does not certify that a document is authentic; the reviewer remains responsible for the outcome. For the wider picture, see the industry verification guide, our article on HR document verification, diplomas and right to work, and how data is handled. Pricing is on the tariffs page.

Frequently Asked Questions

Which DBS check does a care worker need?

It depends on the duties. Personal care for an adult needs an enhanced check with the Adults' Barred List, including in the client's home. Home help without personal care may need an enhanced check without the barred list if the frequency test is met. Check the GOV.UK eligibility guidance for the specific role.

Can I reuse a DBS certificate from a previous employer?

Only if your policy permits it and the certificate's level and workforce match the new duties. Compare the position on the certificate with the job description and the name and date of birth with the passport. A lower level than the role needs means a new application.

What if the name on the qualification differs from the passport?

Ask for the link document, such as a marriage certificate or deed poll, and file it. Then confirm the award with the issuer. A difference with an explanation and a record is acceptable; a difference without either stays unresolved.

Does a share code prove the person is who they say they are?

It shows the right-to-work status held by the Home Office. You still compare the photograph and details on the result with the person in front of you and with the other documents.
