Storage mezzanine floors
A storage mezzanine is the simplest kind: a steel deck for shelving, boxed stock, archives or spares, reached by one staircase and loaded through a pallet gate. Kept small and used only for storage by a few staff, it can often go without a fire-rated ceiling, which keeps it the cheapest mezzanine per square metre. A 50 m² storage floor typically costs £12,300 to £25,900, and 100 m² about £15,700 to £36,000.

Good reasons for a storage mezzanine
- Shelving, archives or spares are taking up ground floor space that could earn money.
- Stock is light enough to go on shelving or in totes rather than on pallets.
- You have about 5 metres or more of height and an area free of overhead services.
- Only a few trained staff will go up there, and never the public.
- You want a structure that can be moved to new premises when the lease ends.
- The floor can stay under 20 metres in each direction, keeping fire protection out of the price.

Ranges built from published figures: The Mezzanine Company (July 2026), Western Industrial (October 2026), Checkatrade (September 2026) and MyBuilder (October 2026), read 26 October 2026. Each includes one staircase, handrail on two open sides and building control. Figures exclude VAT at 20%, which most VAT-registered businesses can reclaim. A guide, not a quote. Add a pallet gate (£1,000 to £1,200) if goods will go up by forklift. The cost calculator works out a range for your floor.
What a good quote includes
Ask for these six points in writing. Two quotes that cover them can be compared line by line.
Design load, in writing
The uniformly distributed load in kN/m² and the point load the deck is designed for. General storage and shelving is commonly designed at 4.8 kN/m²; archives of paper are heavier than they look.
Plan, grid and heights
A drawing with the deck size, column positions, the finished floor level and the clear height left under and over the deck.
Deck and finish
Board type and thickness (for example P5 chipboard, plywood, steel or concrete), plus any anti-slip or painted finish.
Fire protection
Whether the floor qualifies as a storage floor that needs no fire-rated ceiling, and if so what smoke detection is still needed under the deck.
Stairs, handrail and gates
How many staircases, their width, the handrail and edge protection, toe boards and any pallet gates, each priced as a line.
Building control and handover
Who applies for building regulations approval, whether the fee is included, and what you receive at the end: calculations, drawings, completion certificate and a loading notice.

Ask for a free quoteHow a storage mezzanine goes in
Survey
The installer measures the building, checks the slab, columns, lights, sprinklers and doors, and asks what the floor will carry and how goods and people will reach it.
Design and quote
A layout drawing with the load rating, column grid, stairs and fire protection, then a written price. Expect to compare two or three designs, not just prices.
Building regulations
Drawings and structural calculations go to building control, from the council or a registered building control approver, before work starts.
Install
Columns, beams and deck go up first, then stairs, handrail, gates and any fire-rated ceiling and column casings. Most floors take days to a few weeks on site.
Sign-off
Building control inspects and issues a completion certificate. You should also receive the drawings, calculations and a loading notice to display on the floor.
Questions people ask
Can a storage mezzanine go without fire protection?
Often, if it is small and storage only. Approved Document B (paragraphs 7.6 and 7.7) allows raised storage floors used by few people, and never the public, to be treated differently. Industry guidance from Rapid Racking in Logistics Matters says floors over 10 metres in any direction need smoke detection underneath and floors over 20 metres need a fire ceiling, fascia and column casings unless the building is sprinklered.
How much can a storage mezzanine hold?
Western Industrial lists 4.0 kN/m² for archives and 4.8 kN/m² (about 480 kg per m²) for general storage and shelving. A loading notice should be fixed by the stairs so staff know the limit.
Can I move a storage mezzanine to new premises?
Freestanding bolted mezzanines can be taken down and rebuilt, though the new building will have different heights and slab, so expect some redesign and a new building regulations application.
Is a ladder enough to reach a storage mezzanine?
Not as a rule. Approved Document K points industrial buildings to BS 5395-3 for stairs, ladders and walkways, and a fixed ladder is not an acceptable escape route for the public. Most storage floors have a proper staircase.
Do I need building regulations approval for a mezzanine?
Yes, in almost every case. A mezzanine adds structure and changes how people escape in a fire, so it is building work under the Building Regulations. The installer usually prepares the drawings and calculations and makes the application to the council or a registered building control approver.
