Missing a PAT testing deadline doesn't trigger a fine by itself, but it removes the evidence that protects you if something goes wrong afterwards. That gap shows up in three places: a breach of the contract you're delivering against, a weaker position with your insurer if an incident follows, and a compliance gap that surfaces the moment a client or auditor asks for records you don't have.

None of those three outcomes need an incident to happen first. Each one can surface through a routine check on its own, without a failure ever happening. What that check looks like is different for each.

The three consequences of a missed PAT deadline

Contract and SLA breach

Compliance evidence increasingly sits inside the KPIs a contract is scored against, not as a separate checkbox. That means a missed PAT date can cost you on a scorecard even in a quarter where every job was delivered on time and every engineer hit target. Some contracts go further and name compliance currency as a condition of renewal, which turns a single missed retest into a conversation about the whole relationship instead of one appliance.

A weaker position with your insurer

There's no single rule here, because policy wording varies by insurer. What generally holds is that commercial insurance expects reasonable evidence that electrical equipment is maintained, and a missed test can complicate a claim if an incident follows it. Some insurers ask for compliance evidence as part of renewal underwriting, before anything has gone wrong, which means a gap in your PAT register can show up as a harder renewal conversation or a loaded premium, well before it ever gets near a refused payout. Check your own policy wording, a broker call is worth more here than a guess.

Audit and compliance exposure

HSE will consider prosecution where the law has been breached and it's in the public interest, weighing the seriousness of the breach against the potential for harm, and electrical inspectors can recommend it under legislation including the Health and Safety at Work etc Act 1974 and the Electricity at Work Regulations 1989. In practice, most PAT gaps never reach that level. What's more common is a client's own auditor or a facilities compliance team asking to see the register during a routine review, not a regulator turning up after an incident. That's the exposure that bites most businesses: failing a check that a bigger client runs on its own supply chain as standard practice, not a regulator's prosecution.

The Provision and Use of Work Equipment Regulations 1998 (PUWER) adds a more specific duty: work equipment must be inspected at suitable intervals to catch deterioration before it's dangerous. PAT testing is the standard way businesses meet that specific requirement.

Why PAT deadlines get missed

Three gaps cause almost every missed deadline: nothing prompts the retest until someone checks for it, subcontractor evidence doesn't always make it back to the office, and the manual system that worked at ten sites breaks down once the estate grows.

Nothing prompts the retest until someone happens to look

A spreadsheet or wall calendar holds a date, it doesn't chase one. If nobody opens the file that week, nobody notices, and the first sign of it is usually someone else asking about it later.

Subcontractor evidence doesn't always make it back

Where a subcontractor carries out PAT testing instead of your own team, the record depends on them sending it over. For the Office Manager chasing that paperwork, a completed test with no certificate on file looks identical to a test that never happened, until someone's asked to produce one.

What worked at ten sites doesn't hold at fifty

A single spreadsheet is manageable when one person owns it and the site count is small. Add more sites, more subcontractors, and more staff turnover in the office, and the same system starts dropping dates without anyone deciding to let it. This is particularly common in wider electrical maintenance operations running PAT alongside emergency lighting tests and reactive callouts across the same sites.

What to do if you've already missed a PAT deadline

Retest the appliance as soon as you can, rather than waiting for the next scheduled round to catch it. The gap itself isn't fixable after the fact, but a fast retest closes it and gives you a current record to point to if anyone asks.

Alongside the retest, three things are worth doing straight away:

1. Log the gap alongside the new result. Record when the appliance should have been tested and when it actually was, don't just update the file with the new pass date. If you need a refresher on what a complete record should include, see our guide on PAT test certificates. A visible gap with a fast correction reads far better with an auditor or client than a record that skips the missed date without explanation.
2. Check whether the appliance was used during the gap. If it was in service between the missed date and the retest, note that too. It's the more honest record, and it's the one a client or insurer will trust if the rest of your register holds up.
3. Flag it to whoever owns the client relationship. If the missed test sits inside a contract with SLA or compliance terms, raising it before the client finds it themselves is a very different conversation to being asked about it at review.

How Joblogic closes the gap that causes missed deadlines

Joblogic's PAT testing software is built around exactly this problem, keeping retest dates, evidence, and client visibility in one place instead of split across a spreadsheet and someone's memory.

Retest dates that don't depend on someone remembering

Joblogic's planned maintenance scheduling sets a retest interval against each asset and generates the job automatically when it falls due. The date isn't sitting in a spreadsheet waiting for someone to check it, it's what triggers the work in the first place.

One record per asset, not one file per site

Every test result, certificate, and retest date lives against the asset itself, so the history travels with the appliance regardless of which engineer tested it or which site it's on. When a client or auditor asks for a specific item's record, it's a lookup, not a search.

Subcontractor evidence that doesn't rely on an email arriving

Where PAT testing is carried out by a subcontractor, Joblogic's subcontractor portal tracks their compliance documents and job performance directly, so a completed test and a missing certificate stop looking identical from the office.

A client who can see the schedule doesn't need to ask about it

Joblogic's customer portal gives clients direct visibility of upcoming and completed PPM schedules. A missed date stops being something a client discovers at contract review and becomes something they'd have already seen coming, the same as you would.

Contract performance you can see before it's raised at you

Joblogic's contract management gives SLA tracking and performance visibility at the contract level, so a compliance gap shows up on your own dashboard before it shows up as something a client raises at review.

Evidence captured on site, not reconstructed afterwards

Joblogic's mobile forms let engineers complete compliance checks, capture photos, and record signatures directly on site, so the record exists at the point of work instead of depending on someone writing it up later.

Getting ahead of the next PAT deadline

Knowing the knock-on effects of a missed PAT deadline should make you feel proactive enough to check how your own retest dates actually get triggered right now. If that's a spreadsheet someone has to remember to open, ask what happens the week they're on leave, the week a subcontractor changes, or the week you're covering three extra sites during a busy patch. Those are the weeks a date gets missed, and the client, insurer, or auditor asking about it afterwards won't care whose turn it was to check.

Frequently asked questions

Does a missed PAT deadline invalidate my insurance?

Not automatically, and there's no blanket rule that applies across every policy. Commercial insurance generally expects reasonable evidence that electrical equipment is maintained, so a missed test can complicate a claim or a renewal if an incident follows it. Whether it affects cover depends on your specific policy wording, so check with your insurer or broker directly.

Can a client end a contract over a missed PAT deadline?

It depends on what the contract says. Where compliance evidence is written in as a condition of the contract or a factor in performance scoring, a missed date can be raised at review or count against you commercially, even without an incident. Where it isn't specified, it's less likely to trigger anything on its own, but it's still worth flagging before the client finds it themselves.

If a subcontractor misses a PAT deadline, is that my liability or theirs?

The duty to keep equipment safe usually sits with the employer or landlord, not the subcontractor carrying out the test. That means a missed deadline can still land back on you commercially and legally, even if the subcontractor was responsible for doing the work. Contracts with subcontractors should set out who tracks and confirms retest dates, to avoid this gap.

What's the first thing to do if I find a lapsed PAT test?

Retest the appliance as soon as possible instead of waiting for the next scheduled round. Log both the missed date and the actual test date instead of only the new result. A visible gap with a fast correction holds up far better with a client, insurer, or auditor than a record that skips over it.
