How to Manage Uniform Size Exchanges for Your Staff

The simplest way to manage uniform size exchanges is to prevent most of them and to write down the rest. Measure staff before ordering, agree the supplier’s exchange terms before paying, give staff one route for reporting a poor fit, and keep fit problems apart from faulty goods. This guide sets out each step for UK employers, with notes on where the law stands for personalised garments.

TL;DR

• Most exchanges start at the ordering stage. Use a sizing set or the supplier’s garment-specific size guide, and record each person’s size against their name.
• Personalised or custom-made items are among the goods that need only be refunded if faulty, so agree exchange terms with the supplier in writing before the order is placed.
• Give staff one named contact, one form and one deadline for reporting a poor fit.
• Treat a faulty garment and a wrong-size garment as two separate processes with separate records.
• Keep a small, tracked log of exchanges. It shows which sizes, styles or suppliers cause the problems.

Why uniform exchanges go wrong

Exchanges rarely come from one big mistake. They build up from small gaps: a size guessed by a manager, a style that runs differently from the one worn last time, a new starter ordered in a hurry, a garment that shrinks in the first wash. Each gap is minor. Across a team of 40 or 400, they produce a steady flow of parcels going back and forth.

Three features of business uniform orders make this harder than a normal clothing purchase:

• The wearer is not the buyer. The person who orders (an office manager, HR lead or procurement officer) is not the person who has to wear the garment for eight hours.
• Personalisation limits the way out. Once a logo or name is embroidered or printed, the garment cannot easily be resold, which affects what a supplier can accept back.
• Volume multiplies small errors. One wrong-size polo is a nuisance. A box of 30 in the wrong cut is a delay to the whole roll-out.

A clear process deals with each of these in turn.

Get sizing right before the order

Use a sizing set or a garment-specific guide

NHS Supply Chain advises ordering from a sizing set or the garment-specific sizing guide, and says wearers should not simply size up or down, because the uniform is designed for movement and comfort. The same logic applies to any workplace. A person who normally wears a medium in high-street clothing may need a different size in a tailored work polo or a hi-vis jacket cut for layers.

A sizing set is a group of sample garments in each size. Staff try them on, and the manager records the result. If a supplier can send samples, or the business can visit a showroom, this removes most of the guesswork. Where it cannot, ask staff to measure a garment they already own and compare it with the size chart for the specific product, not a general chart.

Plan a fitting session for larger teams

For teams above a dozen or so, a single fitting session is faster than collecting sizes by email. Our guide to planning a uniform fitting day covers the logistics: who attends, what samples are needed and how to record the results. The session also lets people raise comfort concerns before the order is placed, which is cheaper than raising them afterwards.

Record sizes properly

A usable size record has these columns:

Size records are personal data about employees, so limit who can see them and delete them when they are no longer needed. Keep the sheet to what is necessary for ordering and exchanges.

Allow for shrinkage and fabric

Some fabrics change after washing, and a garment that fitted on day one may not fit after a month. Testing a wash before a bulk order avoids a wave of exchanges later. Our note on workwear shrinkage and test washing explains what to check. Fabric choice matters too: the difference between ripstop and twill affects how a garment sits and wears.

Know the rules before you order

What the law says about personalised goods

The legal position is different for consumers and for businesses, and it is worth being clear about which applies. GOV.UK states that personalised or custom-made items are among goods that need only be refunded if faulty. For online shoppers, customised goods are an exception to the 14-calendar-day right to change their mind and return goods.

The practical consequence: a branded garment that is the right quality but the wrong size is not automatically returnable. Whether the supplier takes it back is a matter of the supplier’s own terms and the agreement made at the order. A business buying uniforms for staff is not in the same position as a consumer, so do not rely on consumer cancellation rights. Get the terms in writing.

Questions to ask the supplier before paying

Before placing a bulk order, put these questions to the supplier and keep the answers with the order confirmation:

1. Are size exchanges accepted on personalised items? If yes, on what conditions: unworn, unwashed, tags attached, original packaging?
2. What is the time limit? Seven, fourteen or thirty days from delivery are all common. Ask for the actual figure.
3. Who pays for carriage? Return and replacement postage can be the business, the supplier or split.
4. Is the logo re-applied at cost? An exchange for a different size on a decorated garment may need a new embroidery or print run.
5. Is stock available in every size? A replacement size is no use if it is out of stock or on a long lead time. Ask whether the style is a continuing line.
6. What are the lead times for a replacement? Include decoration time, not just dispatch.
7. Is a spare allowance possible? Some businesses order a small number of extra garments in common sizes to cover swaps.
8. How are faults handled? See the section below.

A supplier that answers these clearly is a supplier that has dealt with exchanges before.

Plan an overage for common sizes

Where the supplier will not take back decorated items, a small reserve of extra garments in the middle of the size range is often the cheapest protection. The reserve covers swaps, new starters and replacements without a new order. How much to hold depends on turnover and team size, so base it on your own exchange log rather than a rule of thumb.

Set up an internal exchange process

The London Fire Brigade’s uniform policy is a useful model of a documented process, even for a business far smaller. Its Policy 533 says the manager and the individual must ensure issued uniform is a suitable size and fit. For ill-fitting items, the individual emails a central purchasing unit for return instructions, quoting the original order ID where possible, and replacement requests go through the ordering system. Exchange items must be returned under the stated procedure, unmarked and in original packaging where possible.

The points worth copying:

• Responsibility is shared. The manager and the wearer both check fit at issue.
• There is one route. Staff do not contact the supplier or guess who handles it.
• The order reference travels with the return. This lets the supplier match the return to the order.
• Condition is stated up front. Returns must be clean and in their packaging.

A seven-step workflow

1. Issue with a fit check. When garments are handed out, the wearer tries them on straight away. Do not wait for the first shift.
2. Set a reporting window. For example, staff report fit problems within a stated number of days of issue. Choose a window that matches the supplier’s own time limit, with a margin.
3. Report to one contact. A single email address or form, with name, garment, size held, size needed and order reference.
4. Approve and log. The contact checks stock and the supplier’s terms, approves the swap and records it.
5. Return the garment properly. Unworn, unwashed, in its packaging, with a returns reference if the supplier gives one. Keep proof of postage.
6. Confirm the replacement. Check the replacement size on arrival and update the size record.
7. Review quarterly. Look at the log for patterns.

Tell staff what they can and cannot do

A short written instruction, one page at most, prevents most disputes. It should say:

• Do not wash or alter a garment you intend to exchange.
• Do not remove tags or packaging until you have tried it on.
• Report the problem to the named contact, not to the supplier directly.
• Expect a decorated garment to take longer to replace than a plain one.

For sectors with their own rules, such as education staff uniforms or customer-facing hospitality roles, add anything that affects appearance standards or hygiene.

Keep fit exchanges and faulty goods separate

A garment that does not fit and a garment that is defective are different problems with different routes. Mixing them leads to confusion about who pays and which deadline applies.

Two habits help. First, inspect every delivery on arrival, before sorting garments into staff bundles, so defects and picking errors are found at once. Second, never accept “wrong size” as the explanation for a fault, or the reverse. A mis-embroidered logo, a damaged seam or a wrong colour belongs in the fault log even if the wearer also needs a different size.

If the logo or name is wrong, check the artwork approval. Where the order matched the approved proof, the supplier may treat it differently from a decoration error. Placement choices are covered in our guide to names on uniforms.

Track exchanges to reduce them

An exchange log needs only a few fields: date, name, garment, style code, size issued, size received, reason, cost and outcome. After a quarter, look at it for patterns:

• One style, many exchanges. The cut may run small or large. Change the style, or add a note to the size guide for staff.
• One size, many exchanges. Staff may be ordering a size too small or too large, which suggests the sizing method is not working.
• One supplier, many faults. Raise it with the supplier, or reconsider the supplier.
• New starters. If most exchanges come from new starters, add a fitting step to onboarding.

The log also supports your next order. A business that knows the size distribution of its team can order a sensible mix rather than an even spread.

For multi-site teams, use one master size sheet owned by one person, not a copy on every site. Standard retail size charts do not always match workwear cuts, so confirm each style against its own guide.

Our approach to size exchanges

We supply personalised, branded and custom workwear and uniforms to construction, hospitality, education and security customers, and the same pattern appears across all of them: exchanges are cheapest when the decision about fit is made before the garment is decorated.

Our advice, in order of priority:

• Fit first, decorate second. Where possible, try plain samples in the sizes you expect to need before the order goes to embroidery or print. A showroom visit is a straightforward way to do this.
• Approve the proof, then check the size sheet. Artwork approval covers how the logo looks. It does not check that the sizes are right. Treat the size list as a second approval step with its own sign-off.
• Ask about terms early. Raise exchange conditions when requesting a quote, not after the order is delivered.
• Order by role, not by habit. A kitchen team, a front-of-house team and a site team need different cuts and layers. A single style across all of them produces exchanges.
• Keep the record. A business that holds its own size sheet reorders faster and with fewer mistakes.

These are working principles drawn from how uniform orders are placed, and the specific exchange conditions on any order are the ones confirmed in the quote and order terms.

Ordering uniforms with fewer exchanges

Cwear supplies personalised polo shirts, t-shirts, jackets, hoodies, PPE and hi-vis workwear, with embroidery and printing, bulk pricing and artwork mock-up approval. Teams can order online, request a quote or visit the showroom to check sizes before placing a larger order.

To start, browse the corporate wear collection or the hospitality range, then contact the team through cwear.co.uk with your quantities and sizes. Ask for the exchange terms in writing with the quote.

Common mistakes to avoid

• Ordering by guess. A manager estimating sizes from appearance is the most common cause of bulk exchanges.
• Assuming personalised items can be returned. They need only be refunded if faulty, so agree terms in advance.
• Letting staff wash a trial garment. A washed garment is unlikely to be accepted back.
• Having no deadline. Without a reporting window, requests arrive after the supplier’s limit has passed.
• Mixing fault and fit records. It hides supplier quality problems.
• Not updating the size sheet after an exchange. The next reorder repeats the error.
• Ignoring spares. One missing size can hold up a new starter for weeks.

FAQ

Can a supplier refuse a size exchange on personalised uniforms?

Yes, in many cases. GOV.UK says personalised or custom-made items need only be refunded if they are faulty, so a change of size is a matter of the supplier’s terms. Ask for the exchange conditions in writing before ordering.

How long should staff have to report a poor fit?

Choose a window shorter than the supplier’s own time limit, so there is time to act. Make it a fixed number of days from issue and put it on the one-page instruction for staff. Check the supplier’s stated limit first.

Who should pay for uniform exchanges?

That depends on the cause and the agreed terms. Where the supplier’s error or a fault is the cause, the supplier normally bears it. Where the size was chosen wrongly, many suppliers expect the buyer to pay carriage or redecoration costs, so confirm this before the order.

What should we do if a garment arrives faulty?

Photograph the fault, note the order reference and report it to the supplier straight away, using the fault route rather than the size-exchange route. Record it in a separate fault log. Keep the garment and packaging until the supplier replies.

How can we reduce exchanges on the next order?

Use a fitting session or sizing set, record sizes by name and style, and review your exchange log before reordering. Test-washing a sample also catches shrinkage. Order a small reserve in common sizes if the supplier will not take decorated items back.
