Factory mezzanine floors
In a factory, a mezzanine usually becomes working space: an assembly or packing line, a quality lab, a stores and kitting area, or offices and welfare over production. People work on it every shift, so it is designed as a workplace, with fire protection, escape routes within the travel limits and a load rating that suits the work. A 100 m² production floor typically costs £19,400 to £47,500 with one staircase and lighting.

Why factories add mezzanines
- Production needs to grow but the site cannot expand outwards.
- Kitting, packing or stores can move upstairs and free the main floor for machines.
- Offices, a canteen or changing rooms are needed close to the line.
- There is clear height above lower machinery that is going to waste.
- Forklift or goods lift access is possible for parts and finished goods.
- You want to keep the line running while the work is done.

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. Goods lift figure from Stannah. Services such as compressed air, extraction and power to machines are extra. 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. Production floors often need 7.2 kN/m² or more; list machines with their weights and footprints.
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
The fire-rated ceiling and casings, detection, emergency lighting and how far anyone on the floor is from a staircase.
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.

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 around production
Work is planned in zones, at weekends or around shifts, with the area cordoned off so the line can keep running.
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 far can workers be from a staircase on a factory mezzanine?
For normal hazard industrial use, Approved Document B (Table 2.1) gives 25 metres where escape is in one direction only and 45 metres where there are alternatives. Higher hazard processes drop to 12 and 25 metres.
Can a mezzanine be installed while the factory keeps working?
Usually, yes. Installers fence off the area, deliver steel out of hours and phase the work. Tell them your shift pattern and any areas that can never close.
What handrail height does a factory mezzanine need?
Approved Document K gives 1100 mm guarding at landings and floor edges in factories and warehouses and 900 mm on stairs. Toe boards stop items being kicked off the edge.
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.
