Gaps in Employment History: How to Screen Them, Document Them and Make a Decision That Stands Up to Scrutiny

The Number That Should Change How You Think About This

More than half of all candidates screened in the UK now have a gap on their CV. Industry data puts the figure at 53%, with half of those gaps running for six months or longer. That means employment history gap decisions are not the exception in your hiring process. They are the rule. You are making them every week, often every day, and the question is whether you are making them consistently, compliantly and in a way that would stand up to scrutiny if you were ever asked to explain them.

Most organisations are not. In my experience, gaps in employment history are the single area where the most risk sits quietly in plain sight.

What Most Organisations Get Wrong

Here is what I saw throughout 18 years of running employment screening. A candidate has a gap. Someone asks about it informally during the interview. The candidate gives a reasonable sounding explanation. The recruiter makes a mental note, or more often no note at all, and the file moves forward. The gap is treated as explained because a conversation happened.

That is not a compliant process. It is a conversation. The two are not the same thing.

What most organisations do not have is a consistent, documented approach to how gaps are identified, investigated, evidenced and recorded. They do not know what their relevant standard requires. They do not know when a statutory declaration is appropriate. And they do not realise that accepting an explanation without supporting evidence is not the same as verifying it.

I also saw the opposite problem regularly: organisations demanding medical certificates or detailed personal statements for gaps that were entirely innocent and where no standard required that level of evidence. That creates candidate relations problems and potential Equality Act 2010 exposure. A proportionate process is the only defensible one.

What Your Gap Process Actually Needs to Cover

What counts as a gap

For screening purposes, a gap is any period within the required screening timeframe not accounted for by verifiable employment, education or documented activity. The threshold that triggers investigation depends on the standard that applies to you.

Under BS7858, which governs the security sector, any gap of 31 days or more within the required screening period must be investigated and documented. The standard requires a five-year employment history verified to source wherever possible, with a documented gap analysis for any period not covered by direct employer verification.

Under BPSS, updated in 2024, employers must enquire about gaps exceeding six months, consecutive or cumulative, within the past three years. The emphasis is on enquiry and explanation rather than extensive documentary evidence for every gap.

Outside regulated standards, most organisations have no formal gap policy. That does not mean gaps can be ignored. It means the organisation is applying its own judgement, and that judgement needs to be consistent, proportionate and recorded.

The three things your gap process must do

Identify gaps systematically. Do not rely on the candidate to volunteer them. Build the identification into your process. Map every month of the required screening period against the application. Any unexplained period needs to be flagged before you ask the candidate anything.

Obtain an explanation and assess it. Ask the candidate directly what they were doing during the gap. Career break, travel, caring responsibilities, illness, redundancy, working for themselves. The explanation is not the end of the process. The question is whether it is plausible, consistent with the rest of the history and supported by anything.

Record your decision and why you made it. This is the part most organisations miss. It is not enough to obtain an explanation. You need a written record of what the candidate said, what evidence you considered, what you concluded and why. If the gap is accepted without supporting documentation, record why that was proportionate in this case.

When is a statutory declaration appropriate

A statutory declaration is a formal legal document in which the candidate declares, under oath before a solicitor or commissioner for oaths, what they were doing during the gap. It is not a first resort. It is appropriate when a candidate cannot provide any documentary evidence and the gap is significant enough to require more than an unsupported verbal account.

In BS7858 screening it is a recognised route when other evidence is unavailable. The key point is that it carries legal weight an informal explanation does not. If the declaration later proves to be false, the candidate has committed a criminal offence.

The Consequences of Getting This Wrong

An undocumented gap decision creates risk in three directions.

Under BS7858 and BPSS, an uninvestigated or undocumented gap is a compliance failure that an auditor will find and require you to explain. A verbal account to an auditor that gaps were discussed with candidates is not sufficient.

On negligent hiring, if an employee causes harm and it later emerges that a gap in their history concealed something relevant, the question becomes what steps the employer took. An undocumented gap is very difficult to defend.

On discrimination, inconsistent gap handling applied differently to different candidates creates Equality Act 2010 exposure. A consistent, written process is the only protection against a claim that gaps were treated differently depending on who the candidate was.

Charlotte Has the Answers at the Point You Need Them

Charlotte is the United Kingdom's first AI compliance advisor built entirely on specialist employment screening and vetting expertise. She is not a search engine and she is not a guidance document. She covers 65 specialist topic areas across the full scope of UK pre-employment screening, vetting, compliance and risk, built on 18 years of real operational experience.

On employment history gaps specifically, Charlotte can tell you exactly what your applicable standard requires, when a statutory declaration is appropriate, what a compliant gap record must include and how to handle specific scenarios at the exact point the decision needs to be made.

To give you a sense of what Charlotte can do on this topic, here is the question I put to her and the answer she came back with.

Question put to Charlotte: A candidate has a seven-month gap in their employment history and says they were travelling. What do I need to do to document this gap compliantly, and is a statutory declaration appropriate here?

Charlotte's answer: A seven-month gap requires proper documentation regardless of the explanation given. Start by recording the candidate's account in writing: the dates covered, the explanation provided and by whom it was given. Then consider what evidence is available to support it. For a travel gap, a passport showing entry and exit stamps, travel bookings or bank statements covering the period are all reasonable forms of corroborating evidence. You do not need all of these, but you should seek at least one form proportionate to the role and applicable standard. A statutory declaration is appropriate where the candidate genuinely cannot produce any supporting documentation and the gap falls within a period your standard requires you to verify. Whatever route you take, the outcome should be a written record capturing the gap dates, the explanation given, any evidence reviewed or why none was available, and the decision reached, signed and dated by the person who made it.

Charlotte provides expert guidance based on 18 years of real operational experience in UK employment screening and vetting. She does not provide legal advice. For legal matters specific to your organisation, always consult a qualified solicitor.

The HMRC 5 Year Statement is one of the most underused tools available for closing employment history gaps with a credible, independent source. It shows what a candidate was actually paid and when, covering a five-year period, and is particularly useful where a previous employer cannot be contacted. I covered how to obtain and use it correctly here: https://vettinghub.co.uk/post/employment-referencing-hmrc-statement-employer-guide

Unexplained gaps can also indicate right to work risk. A candidate who cannot account for a significant period in the UK may have been working without the right to do so. Right to work checks and employment history gap analysis work together, and if your right to work process has weaknesses of its own, the risk compounds.

Frequently Asked Questions

What counts as a gap in employment history for screening purposes?

A gap is any period within the required screening timeframe not accounted for by verifiable employment, education or documented activity. Under BS7858, any gap of 31 days or more must be investigated and documented. Under BPSS, gaps exceeding six months within the past three years must be addressed. Outside regulated standards, gaps that cannot be explained or accounted for should always be recorded and assessed.

Do I need documentary evidence for every employment gap?

Not always. The requirement depends on the standard that applies and the nature of the role. What is always required is a documented record of the gap, the explanation given and the decision reached. For significant gaps or regulated roles, supporting evidence is strongly recommended. For shorter gaps in lower-risk contexts, a properly recorded explanation may be proportionate.

When should I use a statutory declaration to cover an employment gap?

When a candidate cannot produce any documentary evidence for a gap that falls within a period your standard requires you to verify. It is a formal legal document signed under oath before a solicitor or commissioner for oaths. If it later proves to be false, the candidate has committed a criminal offence. It is not a first resort but it is a legitimate and recognised route, particularly under BS7858.

What are the consequences of not documenting employment gaps properly?

Under BS7858 and BPSS, an undocumented gap is a compliance failure an auditor will identify. Beyond regulated standards, poor gap documentation creates negligent hiring risk if something later goes wrong with the employee. Inconsistent gap handling across candidates also creates Equality Act 2010 exposure if it can be shown that different candidates were treated differently without a documented, proportionate basis.
