Racking Changes, Fabric Risks: Asbestos Control in UK Warehouse Reconfiguration

The project brief usually starts in the wrong place

A warehouse reconfiguration commonly begins with a layout drawing: more racking, a new mezzanine, revised pick faces, additional marshalling space. The conversation turns to loadings, sprinkler coverage, lighting and fire strategy. What is discussed less often is the fabric that will be drilled, fixed to, cut through or brought back into use during the change.

For the duty holder under the Control of Asbestos Regulations 2012, that omission matters. Regulation 4 requires the risks from asbestos in non-domestic premises to be managed, and Regulation 5 requires a refurbishment and demolition survey before work that will disturb the fabric. A warehouse reconfiguration is not merely a change of equipment. It is a construction project with the potential to disturb materials that have sat undisturbed for decades.

As of 2026, the commercial pressure on warehouse space remains strong. Operators are squeezing more storage into existing footprints, subdividing bays, adding picking towers and converting former office or plant areas. Each of those changes can bring people, fixings and cutting tools into contact with asbestos-containing materials that a management survey may only have presumed or assumed.

Where warehouse asbestos actually sits

Warehouses are not uniform, but certain locations recur. The first is the roof. Asbestos cement roof sheets remain common on older industrial stock, and so do coated metal roof linings, vapour barriers and rooflights set into asbestos cement. Fixing new services, adding solar-related penetrations or repairing leaks can disturb these materials. The second is the wall. Asbestos cement wall panels, cladding linings and internal partition boards may be present, particularly where later extensions meet original fabric.

The third is the fire break. Warehouses often rely on compartmentation above racking, in roof voids or within wall cavities. These spaces can contain asbestos-containing boards, sprays or blankets that are not visible from the picking floor. The fourth is the plant room. Boiler rooms, sprinkler risers, electrical intake rooms and old compressor housings may contain pipe lagging, gaskets, millboard and asbestos cement flues.

The fifth is the office pod. Older warehouses frequently retain small administration blocks, canteens or supervisor rooms built into the main shed. Floor tiles, ceiling tiles, partition boards and heater cupboard linings in these pods can contain asbestos. When a reconfiguration removes or relocates such a pod, the works move from simple fit-out into fabric disturbance.

Why a management survey is not enough

A management survey is designed to support day-to-day occupation and maintenance. It is not designed to give a contractor the information needed to drill hundreds of anchors into a roof soffit or cut a new opening through a wall panel. Where reconfiguration is planned, the duty holder should commission a refurbishment and demolition survey from a competent, accredited surveyor. The survey must be intrusive enough to locate asbestos in the areas the project will affect, including concealed spaces, risers, roof voids and the fixings zones for new racking or mezzanine legs.

The scope should be agreed with the designer and principal contractor before the layout is frozen. That allows the survey to follow the project, rather than forcing the project to guess. If access is not possible, the survey report should say so clearly, and the project should carry the resulting presumption into its method statements and permits.

A pre-reconfiguration protocol that works on live sites

Most warehouse projects cannot empty the building. A phased protocol is therefore more useful than a single paper exercise.

First, define the fabric scope. The project team should mark up the layout drawings with every element that will be fixed to, cut, removed or temporarily exposed. That includes racking anchors, mezzanine columns, new lighting, sprinkler drops, electrical containment and any temporary works.

Second, check the asbestos register and survey against that scope. Where the register relies on presumption, arrange sampling or an intrusive survey. Where asbestos is confirmed, decide whether the work can avoid it, protect it or require removal. This decision belongs in the design and programming stage, not on the day the contractor arrives.

Third, coordinate the contractors. Racking installers, mezzanine fabricators, electrical contractors and fire protection specialists may each hold a different view of what the fabric contains. The principal contractor should control the sequence, issue asbestos information to every trade, and ensure permits to work reflect the presence of asbestos-containing materials. Toolbox talks should cover the specific materials on the project, not generic awareness alone.

Fourth, control the live environment. Where works take place near occupied picking areas, segregation, negative pressure units, air monitoring and clear signage may be required. Emergency routes and fire assembly points must remain usable. The duty holder should agree the arrangements with the asbestos contractor and the principal contractor before work starts, and should record them in the project file.

Waste and the closing record

Asbestos waste from a reconfiguration must leave the site through the correct route. Asbestos-containing materials are hazardous waste and should be double-bagged or wrapped, labelled and transported by a registered carrier to a permitted site. Consignment notes and waste transfer records should be retained with the project file. The closing record should also include the survey, the method statements, clearance certificates where removal has taken place, and updated drawings showing where asbestos remains.

That file is not an administrative nicety. It is the evidence that the reconfiguration was planned with the fabric in mind, and it will support the next duty holder, insurer or auditor who asks how the building was managed.

The practical conclusion

A warehouse reconfiguration succeeds when the building is treated as part of the project, not as a backdrop to it. The duty holder who commissions the right survey, coordinates the trades and documents the waste trail will find that the asbestos question is resolved before it becomes a delay. The layout may change, but the duty to manage the fabric does not.
