If you run a builders merchant, your racking is doing one of the hardest jobs on site. It’s holding tonnes of timber, blocks, bagged aggregate and heavy stock, often in a busy yard where forklifts are working in tight spaces all day. It’s easy to walk past it every morning and never really look at it. But racking is a safety-critical system, and how often you inspect it can be the difference between spotting a problem early and dealing with a collapse.

So how often should you actually be checking it? Here’s how we answer that for the merchants we work with.

The Short Answer On Racking Inspection Frequency

There are two layers you need running at the same time.

Someone in-house should be doing a visual check every week. This is a trained member of your own team walking the racking, looking for damage, and knowing when to stop and call for advice.

On top of that, an approved racking inspector should carry out a formal inspection at least once a year. For busier or higher-risk sites, that annual visit may need to become every six months.

Neither one replaces the other. The weekly check catches new damage quickly. The annual inspection is the expert eye that picks up the things a general visual check will miss. A lot of the businesses we speak to think one inspection a year covers them. It doesn’t, and that gap is where accidents happen.

Where The Rules Actually Come From

One thing that causes confusion is that there isn’t a single law that says “inspect your racking every 12 months.” The duty is built from a few pieces sitting on top of each other.

The Health and Safety at Work Act 1974 requires you to provide a safe workplace. The Provision and Use of Work Equipment Regulations 1998 (PUWER) treat your racking as work equipment that must be kept in a safe condition and inspected. The Management of Health and Safety at Work Regulations 1999 require you to assess and control risk.

The practical “how often” then comes from HSE guidance, specifically HSG76 (Warehousing and storage: A guide to health and safety), and from the SEMA code of practice. Between them they set out the layered system of everyday reporting, regular in-house visual checks, and an annual expert inspection.

The key point to understand is that twelve months is a maximum, not a target. If your site is busy, your loads are heavy, or you’ve had knocks and impacts before, more frequent expert inspections are the sensible and often necessary answer.

The Three Levels Of Checking

Good racking safety works on three levels, and each one matters.

The first is everyday awareness. Anyone working near the racking should be trained to recognise damage and report it straight away. This is your early warning system and it costs nothing to put in place.

The second is the weekly visual check. This should be done by a nominated person in-house who has been trained for it. They walk the racking, look for damage, check that loads are within limits, and keep a written record. Crucially, they should know their own limits. If they see something they’re not sure about, they call an approved racking inspector for further advice rather than guessing.

The third is the annual expert inspection carried out by an approved racking inspector. This is the thorough, technical assessment that grades damage properly and tells you what needs to happen and how quickly.

What Actually Damages Racking In A Merchant Yard

When we inspect racking for builders merchants, the same problems come up again and again. These are the things that decide whether a site needs checking more often than the annual minimum.

The most common by far is forklift damage. Trucks working in tight spaces with heavy loads clip frames and beams, and over time that damage adds up. The busier the yard and the tighter the aisles, the more often you need eyes on the racking.

Weather is the next one. A lot of merchant racking lives outside or part-covered in the yard, and we regularly find frames that are corroding. Corrosion weakens racking quietly, so exposed outdoor racking should be watched more closely than anything sitting in a dry, indoor warehouse.

Overloading is another recurring problem. Stores put more weight on a beam or a bay than it was ever designed to carry, often without realising. If your team doesn’t know the rated capacity of the racking, they can’t tell when they’ve exceeded it.

And then there’s the one that worries us most: damage that’s been repaired badly in-house. We often find racking that’s been patched up by someone on site with a repair that doesn’t meet the required safety standard. It looks fixed, so everyone assumes it’s safe, but it isn’t. Racking repairs need to be done to the correct standard with the right components, not improvised.

How Damage Should Be Graded

When an approved racking inspector assesses your racking, damage is graded using a simple traffic-light system, and it’s worth your in-house team understanding it too.

Green means the damage is within the allowable tolerance. It’s recorded and monitored at future inspections, but no immediate action is needed.

Amber means there’s damage serious enough to need repair. The affected racking should be offloaded as soon as practically possible and not reloaded until it’s fixed. Important detail here: if amber damage isn’t dealt with within four weeks, it automatically becomes red.

Red means serious damage. The racking must be offloaded and isolated immediately until it’s put right. This is the point where a rack is at real risk of failure.

Understanding these grades helps your weekly checker know the difference between “keep an eye on it” and “stop, offload this now.”

Why This Matters More Than It Might Seem

It’s tempting to see inspections as an unnecessary cost, especially when the racking looks fine. But your racking is a critical safety system holding heavy loads above people working underneath it. When racking fails, it tends to fail suddenly, and the consequences are serious.

For a builders merchant there are really two risks running side by side. There’s the safety risk to your staff and customers, which is the one that matters most. And there’s the risk to your business. If there were ever a racking accident and it came out that you hadn’t been carrying out regular checks, you’d be looking at reputational damage and a potential fine, on top of everything else. Regular inspection is the evidence that you took your responsibilities seriously.

Put simply, weekly in-house checks plus at least an annual inspection from an approved racking inspector is a small, predictable cost that protects your people, your stock and your business.

Getting Your Racking Checked

At Ashford Retail Services we’ve spent over 30 years working with builders merchants and retailers across the UK, and racking inspection and maintenance is a core part of what we do. We can carry out your inspections, advise on what your in-house weekly checks should cover, and put right any damage we find to the correct standard.

If you’re not sure when your racking was last properly inspected, that’s usually a sign it’s overdue. You can find out more on our racking inspections page, or contact us directly below.
