Locker Planning UK: Layout, Space, Compliance and Installation Guide (2026)

Locker planning is the process of deciding who will use the lockers, what they need to store, how much capacity is required and how the complete installation will work within the available space. A good locker plan considers dimensions, compartment configuration, aisle space, door opening, benches, traffic flow, accessibility, supervision, locking, delivery, installation and future management before products are ordered.

This is the main Total Locker Service planning guide for UK locker projects in schools, workplaces, factories, warehouses, healthcare facilities, gyms, leisure centres and commercial changing areas.

Use this page for the complete planning process, then follow the specialist guides where you need detailed information about room layout, capacity, locker dimensions, aisle width, door clearance, bench spacing, accessibility or installation.

Quick answer: start with the users and what they need to store. Decide whether lockers are assigned or shared, establish peak demand, choose a suitable locker size and configuration, then measure the complete usable space. After that, check locker depth, aisles, open-door clearance, benches, access routes, accessibility, lock choice, delivery and installation conditions.

Plan for the busiest realistic period, not simply how the lockers look in an empty room.

Locker Planning: What Should Be Checked?

Planning area	What to check	Why it matters
User requirement	Who uses the lockers, what they store and when they need access	Determines capacity, configuration and operating method
Locker size	Height, width, depth and compartment count	Controls usable storage and the space occupied by the installation
Capacity	Peak simultaneous demand rather than total headcount alone	Prevents unnecessary lockers or insufficient provision
Door clearance	Open-door projection and user working space	Reduces clashes and blocked routes
Aisle space	Standing, passing and simultaneous use	Supports practical daily movement
Bench spacing	Seated users, standing users and locker access	Prevents changing activity consuming the main circulation route
Access routes	Entrances, exits, corridors and movement paths	Reduces congestion and local pinch points
Accessibility	Approach, reach, door operation, locks and manoeuvring space	Supports a wider range of users
Supervision	Visibility of locker areas and circulation routes	Particularly important in schools and high-use facilities
Zoning	Wet/dry, clean/dirty, PPE, staff and visitor areas	Separates activities that should not compete for the same space
Installation	Delivery access, floors, walls, services and fixing	Prevents avoidable problems when lockers arrive
Management	Numbering, keys, overrides, repairs and spare capacity	Keeps the locker system manageable after installation

What Is Locker Planning?

Locker planning means designing the complete storage arrangement before purchase and installation. It is different from simply selecting a locker product.

A product decision answers questions such as material, colour, size and lock type. A planning decision asks whether that locker will actually work for the users, room and operating conditions.

• Who will use the lockers?
• What will they store?
• How frequently will they use them?
• Are lockers permanently assigned or shared?
• How many people require storage simultaneously?
• What happens during peak periods?
• How much usable space is actually available?
• How will people move through the area?
• Are benches or changing facilities required?
• Does the area require supervision?
• What locking system is appropriate?
• How will the lockers reach the installation area?
• How will the system be maintained afterwards?

Step 1: Start With the Users

The people using the lockers should determine the storage system. Avoid choosing a locker first and then trying to make the users fit the product.

• Permanent staff
• Shift workers
• Pupils and students
• Visitors
• Contractors
• Gym and leisure users
• Healthcare staff
• Sports teams

Different groups create different requirements for storage volume, security, access, supervision and peak-time traffic.

For workplace-specific planning, see our workplace lockers guide. For education sites, see the school locker systems guide.

Step 2: Decide Whether Lockers Are Assigned or Shared

This decision affects locker quantity, lock type, numbering and ongoing management.

Assigned Lockers

An assigned locker remains allocated to one person for an extended period. This is common for permanent employees, pupils and users who need to leave permitted belongings between visits.

• Simple allocation and ownership.
• Suitable where belongings remain stored between uses.
• Keyed or individually controlled locks can work well.
• More compartments may be required because each locker remains reserved.

Shared or Temporary-Use Lockers

Shared lockers are released when one user finishes with them. This can suit gyms, leisure facilities, visitors and some flexible workplaces.

• Can reduce permanently reserved capacity.
• Requires a lock suited to changing users.
• Needs a clear abandoned-item procedure.
• May require reset or override management.
• Requires a clear rule for when a locker becomes available again.

Step 3: Define What Users Need to Store

The contents determine the locker dimensions and internal configuration. A large number of doors is not useful if the individual compartments are too small for the belongings users actually bring.

• Coats and uniforms
• Handbags and backpacks
• Books and school equipment
• Sports kit
• Boots and footwear
• PPE and workwear
• Helmets
• Laptops and electronic devices
• Small personal belongings
• Tools and equipment

Where possible, measure representative bags, boots, helmets, devices or equipment rather than estimating. External locker dimensions alone do not tell you whether the actual contents will fit comfortably.

Use the locker sizes UK guide when comparing dimensions and compartment formats.

Specialist Storage Requirements

Not every storage requirement should be forced into a standard personal locker. Identify specialist items early so the correct storage product can form part of the original plan.

• For laptops, tablets, phones, cordless tools and rechargeable equipment, consider charging lockers.
• For controlled organisational key storage, compare our key cabinets.
• For documents, valuables and items requiring a different level of secure storage, compare our safes.
• For bulky PPE, workwear or equipment, choose the locker around the actual item dimensions rather than standard compartment counts.

Separating these requirements at the planning stage prevents general-purpose lockers being specified for equipment that needs charging, specialist dimensions or a different security approach.

Step 4: Choose the Locker Configuration

Configuration	Typical storage	Planning effect
Single tier	Coats, uniforms, bags and larger belongings	Provides the largest individual storage compartment
Two tier	Bags, clothing and general staff storage	Balances compartment size with user capacity
Multi-tier	Smaller personal belongings	Increases user capacity within a similar floor footprint
Z locker	Hanging garments and workwear	Combines hanging storage with increased user density
Specialist locker	PPE, equipment, charging or operational storage	Specification follows the item or process

Increasing the number of tiers increases the number of compartments, but each compartment becomes smaller. Do not increase theoretical capacity at the expense of practical storage.

Step 5: Calculate Locker Capacity From Peak Demand

Locker quantity should normally be based on the number of people who genuinely require storage at the same time rather than automatically matching total staff, pupil or membership numbers.

• How many users are normally on site?
• How many need lockers simultaneously?
• Do work shifts overlap?
• Do school groups arrive together?
• Can appropriate lockers be shared?
• Are visitors and contractors included?
• What spare capacity is sensible?
• What happens when a locker is temporarily unavailable for repair?

For detailed calculations, use our locker capacity planning guide.

Step 6: Plan for Peak Conditions

A locker arrangement that works when one person uses it can fail when many people arrive together. Test the proposed layout around the busiest realistic period.

• Several locker doors may be open simultaneously.
• Users may stand directly in front of compartments.
• Bags, workwear and sports equipment may temporarily occupy floor space.
• Benches may be fully occupied.
• Incoming and outgoing users may cross.
• Groups may stop and talk beside lockers.
• Queues may form around entrances or popular locker positions.

This is particularly important for school breaks, shift changes, gym peaks, sports teams and other concentrated-use environments.

Step 7: Measure the Complete Usable Space

Do not calculate locker capacity from wall length alone. Record everything that reduces the usable space or affects installation.

• Room length, width and height
• Doors and door swings
• Windows
• Radiators and heaters
• Columns
• Pipework and service ducts
• Electrical sockets and controls
• Steps and floor-level changes
• Benches and other furniture
• Washroom or shower routes
• Entrances and exits
• Cleaning and maintenance access

For an early space calculation, see Minimum Space for Lockers UK.

Step 8: Check Locker Depth and Working Projection

Deeper lockers provide more storage but project further into the room. Assess the complete working space rather than cabinet depth alone.

• Closed locker body
• Open locker door
• User standing at the compartment
• Bags or equipment being handled
• Nearby benches
• Opposing locker banks

A locker can physically fit against a wall while leaving insufficient space for people to use it properly. Dimensions and circulation therefore need to be assessed together.

Step 9: Plan Locker Aisles and Working Space

Aisle space should allow people to stand at lockers while other users move through the room. The appropriate clearance depends on locker arrangement, door swing, user numbers, benches, accessibility and the activity taking place.

Do not treat the aisle simply as empty floor between two cabinet rows. During use it may contain standing users, open doors, bags and people passing in both directions.

Use the locker aisle width guide UK for detailed spacing guidance.

Step 10: Check Locker Door Clearance

Aisle width and door clearance are related but are not the same measurement. Door clearance is the space needed for the locker door to open and for a person to access the compartment.

• Check the actual locker door width.
• Allow for several doors being open simultaneously.
• Check doors close to walls and corners.
• Check interaction with benches.
• Check opposing locker rows.
• Allow users to stand, bend or crouch where necessary.

See the locker door clearance guide UK for this stage.

Step 11: Plan Benches at the Same Time as Lockers

Bench seating should form part of the original room layout rather than being added after all locker positions have been fixed.

An occupied bench requires considerably more usable space than its physical seat depth because users need legroom, space to stand up, room to change footwear and somewhere to handle clothing or bags.

• Keep benches out of important movement routes where practical.
• Check interaction with locker doors.
• Allow room around bench ends.
• Include seated and standing users in the calculation.
• Allow for bags, footwear and clothing.
• Maintain practical cleaning access.

See our bench spacing and clearance guide or browse changing room bench seating.

Step 12: Plan Zones, Not Just Locker Rows

Larger or more complex facilities can work better when activities and user groups are separated into logical zones.

Zone	Typical purpose
Entrance zone	Arrival and orientation
Locker zone	Personal storage and locker access
Changing zone	Benches, clothing and footwear changes
Circulation zone	Movement through the room
Wet zone	Showers, swimming or damp activity
Dry zone	Personal belongings and clean clothing
Clean/dirty zone	Workwear, uniforms or PPE separation
Staff/visitor zone	Separating groups with different access requirements

For more detailed separation and flow planning, use the locker room zoning guide UK.

Step 13: Consider Supervision and Visibility

Visibility is particularly important in schools and other high-use facilities where locker position can affect supervision and concentrated movement.

• Avoid concentrating too many lockers at narrow corridor points.
• Keep classroom and other important entrances reasonably clear.
• Group lockers logically where this reduces unnecessary movement.
• Plan for bags and open doors during busy periods.
• Avoid unnecessarily hidden locker areas where supervision is important.
• Use clear locker numbering and allocation records.
• Check how the space behaves at the busiest points of the day.

The aim is to make locker access easy to understand without creating unnecessary local congestion.

Step 14: Include Accessibility From the Beginning

Accessible locker provision should be integrated into the original layout rather than added after the remaining positions have already been allocated.

• Clear approach routes
• Usable locker positions
• Practical door operation
• Appropriate lock controls
• Movement and manoeuvring space
• Clear numbering and visual identification
• Interaction with nearby bench seating

Accessibility requirements depend on the building, users and project. Use the accessible locker planning UK guide for the detailed planning stage.

Step 15: Choose the Locker Locking System Before Ordering

The lock should match the way the locker system operates. It should not be treated as an accessory selected after the rest of the project has been decided.

Lock type	Can suit	Main management consideration
Key lock	Assigned staff, pupil or member lockers	Replacement keys, spare keys and master-key control
Hasp and padlock fitting	Sites where users control their own padlock	Procedure for lost or abandoned padlocks
Coin lock	Leisure and shared-use applications	Coin operation, override and maintenance
Mechanical combination	Assigned or shared storage without user keys	Forgotten codes and reset procedures
Electronic or RFID	Managed shared-use or controlled-access applications	Credentials, overrides, batteries or power and administration

Compare replacement and upgrade options through our locker locks range.

Step 16: Plan Delivery and Installation Before Ordering

A locker that fits perfectly in the finished room still needs to reach that room and be installed correctly.

• Vehicle and unloading access
• Building entrances
• Door and corridor dimensions
• Stairways and landings
• Lift dimensions
• Tight corners
• Assembly and working space
• Floor condition and level
• Wall condition
• Skirting and projections
• Hidden and visible services
• Linking, restraint and fixing requirements

For the detailed site-preparation stage, see our locker installation planning UK guide.

Step 17: Consider Phased Installation

Schools, workplaces, factories, healthcare sites and leisure facilities may need to remain operational while old lockers are removed and new lockers are installed.

• Install one room, zone or locker bank at a time where practical.
• Plan temporary storage if users still require access during the work.
• Coordinate removal of existing lockers with the new delivery.
• Keep installation materials away from normal users.
• Transfer locker numbers and allocations in a controlled sequence.
• Use lower-occupancy periods where practical.

Step 18: Plan Numbering, Keys and Ongoing Management

The locker project continues after installation. Numbering, key control, maintenance and spare capacity should therefore be planned before the system goes into use.

• Number lockers clearly.
• Keep an allocation record where appropriate.
• Control spare and master keys.
• Establish procedures for lost keys and forgotten codes.
• Keep suitable replacement parts available where practical.
• Record lockers temporarily unavailable for repair.
• Allow spare capacity for future users.
• Plan routine cleaning and inspection.

Replacement keys for many common locker locks are available through our replacement locker key service.

Locker Planning Priorities by Environment

Environment	Main planning risk	Planning priority
Schools	Corridor congestion and supervision	Logical grouping, visibility, clear routes and peak-time movement
Workplaces	Staff changeovers and different storage requirements	Practical locker size, allocation and accessible routes
Factories and warehouses	PPE, bulky belongings and shift patterns	Suitable storage volume, working space and clean/dirty separation where required
Gyms and leisure centres	High turnover and changing-room pressure	Bench clearance, suitable locks, moisture conditions and traffic flow
Healthcare	Staff changing and operational workflow	Logical zoning, suitable access and manageable storage systems
Offices	Hybrid attendance and variable occupancy	Flexible allocation without unnecessary permanently reserved capacity

Locker Planning for Workplaces

Workplace lockers may need to accommodate coats, bags, uniforms, PPE, safety footwear, helmets, tools or electronic equipment. The correct specification depends heavily on the type of workplace.

An office may prioritise compact personal storage and flexible allocation. A factory or warehouse may require larger compartments, PPE storage, footwear space and a room that can handle concentrated shift changes.

Use our Workplace Lockers UK guide for the wider workplace specification process.

Locker Planning for Schools

School locker planning needs to consider more than pupil numbers. Locker location affects corridor movement, supervision, classroom entrances, break-time congestion and the amount of equipment pupils carry.

Different year groups may also require different locker positions or compartment sizes. PE and changing-room storage can require a different solution from corridor storage for books, bags and coats.

See our School Locker Systems UK guide for school-specific planning and management.

Locker Planning for Changing Rooms

Changing rooms introduce additional pressures because locker access, clothing changes, footwear, benches and circulation all happen within the same area.

Plan the complete journey through the room rather than treating lockers and benches as unrelated pieces of equipment. Entrance zones, locker areas, changing space, wet areas and exits should connect logically without forcing several activities into the same narrow route.

For the broader design process, use our locker room design UK guide.

Allow for Future Capacity and Change

Locker requirements change as staffing, pupil numbers, membership, shift patterns and working practices change. A layout that uses every available centimetre on day one can leave no practical way to adapt later.

• Allow sensible spare capacity where possible.
• Consider whether another locker nest could be added later.
• Avoid filling every available wall simply because it is currently empty.
• Keep access to services and maintenance points.
• Choose locker systems that can be repaired and maintained.
• Consider future lock replacement and management requirements.

Common Locker Planning Mistakes

• Choosing lockers before defining the users and storage requirement.
• Measuring available wall length but not the complete room.
• Calculating capacity from total headcount rather than actual simultaneous demand.
• Choosing locker depth without considering circulation space.
• Using too many tiers and creating compartments that are too small.
• Ignoring open locker doors.
• Creating narrow or dead-end aisles in busy areas.
• Adding benches after locker positions have been fixed.
• Positioning too many school lockers at one corridor pinch point.
• Ignoring supervision and visibility.
• Planning for quiet conditions instead of peak use.
• Leaving accessibility until the end of the design process.
• Choosing the lock without deciding how the lockers will operate.
• Ignoring delivery routes, floors, walls and services.
• Using standard lockers where specialist storage is actually required.
• Failing to plan numbering, keys and ongoing management.
• Leaving no spare capacity for growth or temporary repairs.

Plan the Complete Locker System Before Ordering

The strongest locker projects treat the lockers, room, users, locking system and installation as one connected system. Product choice matters, but it should follow a clear understanding of user demand, stored items, available space and how the facility will operate during everyday and peak use.

Once the planning requirements are established, compare our commercial locker ranges for schools, workplaces, healthcare, leisure and changing facilities.
