Plant and machinery inspection records: what LOLER and PUWER actually require

Two separate but overlapping sets of regulations govern plant and machinery on a construction site. LOLER — the Lifting Operations and Lifting Equipment Regulations 1998 — covers equipment specifically used for lifting: cranes, hoists, excavator lifting attachments, lifting accessories like slings and shackles. PUWER — the Provision and Use of Work Equipment Regulations 1998 — covers work equipment more broadly, including plant that isn't primarily used for lifting at all. Most sites run equipment covered by both, and confusing which regime applies to a given piece of plant is a common, avoidable gap in an inspection programme.

LOLER: what it actually requires

LOLER requires lifting equipment to be thoroughly examined by a competent person at defined intervals, with the standard default being six months for equipment used to lift people and for lifting accessories such as slings, chains and shackles, and twelve months for other lifting equipment. A written scheme of examination, prepared by a competent person, can vary these defaults where justified by a genuine risk assessment — but the default intervals are the starting point, not a figure to depart from casually. It's worth checking current LOLER guidance directly for the exact scope of what counts as person-carrying equipment for these purposes, since getting that classification wrong in either direction either over-inspects unnecessarily or, more seriously, under-inspects equipment that needed the shorter interval.

PUWER: what it actually requires

PUWER's inspection requirement is less prescriptive on specific timeframes and more focused on the principle: equipment should be inspected before initial use, after installation or assembly, and at suitable intervals afterwards, with the frequency judged against how the equipment is used and how quickly its condition could deteriorate to a dangerous state. This is a genuinely different structure to LOLER's fixed default intervals — PUWER asks the dutyholder to make a reasoned judgement about frequency based on risk, rather than applying a single fixed number across every type of work equipment. That flexibility is useful, but it also means a PUWER inspection regime is only as good as the judgement behind it — an interval set once, early on, and never revisited as equipment ages or usage patterns change is a common way this requirement quietly weakens over time.

Working out which regime applies to a given piece of plant

A telehandler fitted with forks is generally work equipment under PUWER; the same telehandler with a lifting attachment fitted, being used to lift a load, brings LOLER into play for that specific use. An excavator digging is PUWER; the same excavator, fitted with a lifting eye and used to lower a pipe section into a trench, is LOLER territory for that lift. This dual nature of some plant is exactly where inspection programmes develop gaps — a machine that's correctly logged under a PUWER inspection schedule for its everyday use can be quietly used for occasional lifting without anyone updating the inspection regime to reflect that it now also needs LOLER-compliant examination for that use.

A worked example

A groundworks subcontractor's excavator is on a routine PUWER inspection schedule, checked and recorded as part of general plant maintenance. Partway through the project, the site starts using the same machine, fitted with a lifting attachment, to place precast concrete units — a task nobody originally planned for when the machine arrived on site. If the LOLER thorough examination requirement for that lifting use isn't picked up at the point the task changes, the machine is being used for lifting operations without the specific examination that use requires, even though its general PUWER inspection record looks entirely in order. This is precisely the kind of gap that looks fine on paper and only becomes visible if something goes wrong with a lift — which is also, separately, the kind of incident that would very likely be RIDDOR-reportable as a dangerous occurrence if the lifting equipment failed.

Who's competent to carry out the examination

Both regimes require the person carrying out inspections or thorough examinations to be genuinely competent to do so — which for LOLER thorough examinations specifically tends to mean a suitably qualified, often third-party, examiner rather than someone on site simply looking the equipment over. It's worth being clear about this distinction when reviewing records: a routine visual check by a site operative before use is a valuable daily habit, but it isn't a substitute for the formal thorough examination LOLER requires at the defined interval, and treating the two as interchangeable is a genuine compliance gap even where the routine checks themselves are being done diligently.

What the paperwork actually needs to show

A LOLER report of thorough examination needs to identify the equipment, confirm it's safe to operate (or specify defects and any date by which they must be remedied), and be kept available — this connects directly to the same principle covered in what site inspection records generally need to show: a record that confirms an examination happened is weaker than one that specifies exactly what was checked and what, if anything, was found. A defect noted on a LOLER report with no evidence it was ever remedied is a serious gap, not a minor paperwork oversight, given the equipment involved.

Tracking this across a busy, multi-plant site

On a site running several pieces of plant, each potentially on a different inspection or examination interval, tracking when the next one is due for each item is exactly the kind of leading indicator worth building into how a site tracks its compliance position generally — plant with an overdue thorough examination is a live compliance gap the moment the deadline passes, whether or not anyone on site has actually noticed yet. A site that only discovers a lapsed LOLER certificate when someone happens to ask for it is relying on luck rather than a genuine tracking system.

Hired plant, and whose responsibility the paperwork is

Hired plant complicates this further, because the examination and inspection history often sits with the hire company rather than the site using the equipment, and it's worth confirming at the point of hire — not after the equipment has already arrived and started being used — that current, valid documentation will be supplied and kept up to date for the duration of the hire. A principal contractor accepting hired plant onto site without checking this is effectively taking on a compliance gap created by someone else's paperwork, and it's a far easier problem to catch before the machine arrives than to discover partway through a project.

Why this record-keeping matters beyond the routine

It's easy to think of LOLER and PUWER paperwork as background administration, relevant only if an inspector happens to ask for it. Its real value tends to surface at the worst possible moment — after a piece of equipment has failed and someone's investigating why. A clean, complete history of thorough examinations and inspections, with defects tracked through to remediation, is what lets a business demonstrate the equipment was being properly managed right up until the point something went wrong, rather than leaving that question open when it matters most. A gap in the record doesn't prove the equipment was unsafe, but it removes the ability to prove it wasn't, which is a genuinely worse position to be arguing from.

Common mistakes

• –Applying PUWER-only inspection to equipment that's started being used for lifting operations without adding the LOLER requirement
• –Treating a routine daily visual check by a site operative as equivalent to a formal LOLER thorough examination
• –Not revisiting a PUWER inspection interval as equipment ages or its usage pattern changes
• –Recording that an examination took place without recording specific findings or confirming defects were remedied
• –Accepting hired plant onto site without confirming current, valid examination documentation is included
• –Not tracking upcoming examination due dates centrally, relying instead on someone remembering to check
