Retail mezzanine floors
A retail mezzanine adds sales floor, a stock room or a café level inside a shop or retail warehouse. Customers will use it, so it is built and finished to a higher standard than a storage floor: fire protection, a wide general access staircase, glazed or panelled balustrades and often a lift. In England, a mezzanine that adds more than 200 m² of floor space to a shop needs planning permission. A 100 m² retail floor typically costs £17,700 to £42,500 for the structure, before shopfitting.
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 retail mezzanine fits
- The unit is tall, such as a retail warehouse or a former industrial building.
- Stock takes up selling space on the ground floor and could move upstairs.
- You want to add a department, a café or a click and collect area without moving.
- The landlord allows internal structures and the lease covers the extra floor area.
- There is room for a staircase and, ideally, a lift where customers can find them.
- Your planning position is clear: under 200 m² added, or permission sought first.

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. Glazed balustrades, feature stairs and shopfitting add to these figures. Lift starting price from Stannah (its dumbwaiters). 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. Retail floors take crowds and display stock; ask what rating the installer has allowed and why.
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 full fire package: fire-rated ceiling and column casings, detection, emergency lighting and how customers escape from the far end of the floor.
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 and planning check
The installer surveys the unit and you confirm whether planning permission is needed (in England, if over 200 m² is added) and whether the landlord consents.
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.
Shopfit and sign-off
Balustrades, finishes, lighting and fixtures go in, building control issues a completion certificate, and the floor opens to customers.
Questions people ask
Does a retail mezzanine need planning permission?
In England, yes if it adds more than 200 m² of gross floor area to a building used for retail. The Town and Country Planning (Mezzanine Floors) (England) Order 2006 brought this in under section 55(2A) of the 1990 Act. Hot food outlets are excluded. Smaller floors are usually treated as internal works.
What staircase does a retail mezzanine need?
A general access stair, not an industrial one. Approved Document K limits the rise to 150 to 170 mm and the going to 250 to 400 mm, with no more than 12 risers in a flight in most cases, and guarding at 1100 mm on landings and floor edges in shops.
Do customers need a lift to reach a retail mezzanine?
Access for disabled people is part of the building regulations and the Equality Act, so a public sales floor often needs a lift or platform lift. Ask the installer and building control early, as the lift position shapes the layout.
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.
