Pallet Racking Inspection Frequency — UK Legal Requirements Explained

There is no single regulation headed 'racking inspection'. The duty is assembled from three sources, and understanding that is what makes the frequency question answerable.

First, the Health and Safety at Work etc. Act 1974 places the general duty on employers to ensure health and safety so far as is reasonably practicable, and under section 37 exposes individual directors and managers to personal liability where an offence arises from their consent, connivance or neglect.

Second, the Provision and Use of Work Equipment Regulations 1998. Pallet racking is work equipment, so PUWER applies directly: regulation 5 requires it to be maintained in an efficient state and good repair; regulation 6 requires inspection where safety depends on installation conditions, at suitable intervals, and after exceptional circumstances liable to jeopardise safety; regulation 8 requires adequate information and instructions, which for racking means load notices; regulation 9 requires adequate training for those using and supervising the equipment. Each is covered in more detail on our PUWER racking inspection page.

Third, guidance that puts numbers on 'suitable intervals': HSE guidance HSG76 on warehousing and storage, BS EN 15635 on the application and maintenance of static steel storage systems, and the SEMA codes of practice. Guidance is not law, but it is the benchmark HSE and the courts use to judge whether what you did was reasonable — see also our HSE racking inspection page.

The first tier is not an inspection at all — it is a reporting duty that applies continuously. Anyone working in or around racking who causes or sees an impact reports it straight away to the nominated Person Responsible for Racking Safety (PRRS).

This tier is the one that fails most often, and it fails culturally rather than technically. Where drivers expect to be blamed, impacts stop being reported and damage sits in a loaded bay until somebody with a straight edge happens to walk past. Reporting has to be quick, routine and visibly acted upon, or the other two tiers are working with incomplete information.

Some sites also run a light daily visual sweep of the main traffic routes and aisle ends — the positions where damage recurs. It is not a formal requirement, but it is cheap and it catches the obvious. Where impacts recur in areas nobody is watching, continuous racking impact monitoring records each one with time, location and severity.

The second tier is the regular visual inspection carried out by trained site staff. HSG76 and BS EN 15635 both expect this, and weekly is the interval that fits a working warehouse: short enough that new damage is found within days, long enough to be sustainable.

It is carried out by the nominated PRRS following a fixed route so that every run is covered. The PRRS checks uprights front and rear over their full height, beams and their end connectors, safety clips, bracing including members removed for access and never replaced, baseplates and floor fixings, frame protection and barriers, and whether load notices still match the configuration installed.

Findings are classified green, amber or red against BS EN 15635 tolerances, recorded against a bay reference, and escalated according to colour: green recorded and monitored, amber planned for repair within a defined period, red offloaded and isolated immediately. The classification logic is explained in red, amber and green racking damage explained.

The record is as important as the walk. A written log — paper or digital — showing date, inspector, area covered, findings with bay references and actions with dates is what demonstrates the regime exists. Competence matters too: PUWER regulation 9 expects training, and an untrained inspector produces a record of looking rather than a record of inspecting. Our weekly PRRS training covers exactly this.

The third tier is the expert inspection by a technically competent person independent of the day-to-day running of the site, at intervals not exceeding 12 months. In practice that means a SEMA-Aligned Rack Inspector (SARI).

The expert inspection is more than a bigger version of the weekly check. It measures damage against tolerances in detail, assesses the installation as a system — configuration against original design, beam pitch, load notice accuracy, aisle widths against the MHE in use, protection at pinch points — and reviews the site's own weekly records to establish whether the interim regime is functioning.

The output is a written, risk-rated report with bay references, photographs, classifications and prioritised actions. That report is the document an auditor, an insurer or an HSE inspector will ask for, and it is the evidence that inspection under PUWER regulation 6 has actually happened. Scope detail is on the annual SEMA-aligned inspection page.

Alongside the three tiers sits an inspection that has no interval at all: the one triggered by an event. PUWER regulation 6 requires inspection after exceptional circumstances liable to jeopardise safety, and BS EN 15635 and HSG76 both expect struck racking to be assessed before it returns to normal service.

That means an impact resets nothing and waits for nothing. A bay struck three weeks after a clean annual inspection is offloaded, isolated and assessed before it is reloaded, because the report describes the racking as it was, not as it is. The full sequence is set out in after-impact inspections: the procedure every site needs.

Other events count too: any reconfiguration of beam levels, extension of a run, change of pallet type or weight, relocation of racking, a change in MHE fleet that alters aisle clearances, or structural work affecting the floor slab. Each changes the assumptions the last inspection was based on.

BS EN 15635 asks the operator to set inspection frequency on the basis of risk. Twelve months is the outer limit for a conventional installation in a conventional operation, not a universal answer, and several conditions justify shortening it.

High throughput and high MHE movement counts. Narrow-aisle operations where clearances are tight. Drive-in and drive-through racking, where access is restricted and frame and rail damage carries more consequence. Installations with a documented history of frequent impacts. Cold-store and wash-down environments where corrosion causes section loss. Very tall installations and mezzanine or pick-tower structures. Sites where MHE is operated by frequently changing agency drivers.

Conversely, a small, lightly used stores area in a low-traffic building may genuinely sit at the twelve-month interval with a robust weekly regime. The judgement has to be made and recorded, because 'we do it annually because everyone does' is not a risk assessment.

A workable schedule has four elements written down. Continuous reporting: everyone reports impacts to a named PRRS immediately, and the procedure is displayed where drivers can see it. Weekly inspection: a named PRRS, a fixed route, a written record, and marked bay references on the racking so locations are described consistently.

Annual expert inspection: booked as a recurring commitment rather than remembered, with the interval justified against your risk profile. Event-driven inspection: a written after-impact procedure that does not depend on who is on shift.

Then close the loop. Every amber item gets an owner and a date. Every red bay stays out of service until it is repaired and signed back in writing. Green items are carried onto the weekly route. Do that consistently and the paperwork stops being a compliance chore and becomes an accurate history of your installation. The practical weekly format is in our racking inspection checklist.
