Warehouse mezzanine floors
A warehouse mezzanine puts the empty height under your roof to work: a picking area, a packing line, returns processing or slow-moving stock, with forklift traffic carrying on below. Floors used by staff for picking or packing are treated as workspace, so they usually need fire protection as well as stairs, handrail and pallet gates. A 100 m² floor typically costs £18,700 to £43,700 with one staircase, a pallet gate and lighting.
A free matching service, not a mezzanine floor installer. We find one who covers your area and tell you who they are before anything is shared. How it works
When a warehouse mezzanine makes sense
- The building has 5.5 metres or more to the eaves and the racking does not use the full height everywhere.
- Picking, packing or returns are fighting for floor space with goods in and dispatch.
- You need more space but the lease runs for years, or moving would cost far more.
- Small, light items are stored on the ground floor and could go upstairs on shelving.
- You want a staff area, a mess room or an office looking over the floor.
- The landlord is willing to consent to a freestanding structure that can be taken down.

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.

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. Pallet storage often needs 6.0 kN/m² or more; picking on shelving is commonly designed at 4.8 kN/m².
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 a fire-rated ceiling, fascia and column casings are included, to what period (often 60 minutes), and whether existing sprinklers or smoke detection need extending 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 warehouse mezzanine project usually runs
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
How much weight can a warehouse mezzanine hold?
Whatever it is designed for. Western Industrial lists 4.8 kN/m² (about 480 kg per m²) for general storage and shelving and 6.0 kN/m² for pallet racking, with heavier ratings for production. Tell the installer what will sit on the floor, including pallet trucks, and ask for the rating on the drawings.
How much headroom do I need for a warehouse mezzanine?
Pallite suggests at least 2.4 metres of working clearance above and below the deck and about 5.5 metres to the eaves as a practical minimum, with 7 metres or more being comfortable. The structure itself takes a few hundred millimetres between the two.
How do pallets get onto the mezzanine?
By forklift through a pallet gate, which keeps a barrier between the operator upstairs and the open edge at all times. A goods lift or conveyor suits smaller loads. Plan where trucks will stand below so the gate is not in a busy aisle.
Does a mezzanine need fire protection?
It depends on use and size. Approved Document B lets small storage-only floors used by few people go without fire-rated construction. Industry guidance such as Western Industrial's fire protection guide reads the limits as storage only, under 20 metres in every direction and no more than half the floor area below; once a floor is bigger, used as offices or production, or open to the public, a fire-rated ceiling and column casings are normally needed. Building control has the final say.
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.
