Mirrors and Glass: Packaging, Breakage, and Who Pays

Who legally owes the buyer, and why it isn't really a question

Checked 26 September 2026, and re-confirmed directly again 28 September 2026: Section 29 of the Consumer Rights Act 2015 is specific that goods remain at the trader's own risk until the consumer, or someone the consumer names, physically has them - not until they leave the seller's hands, not until a courier accepts them, but until the buyer actually holds the item. This means a mirror that arrives shattered is the seller's responsibility to put right - a replacement or a refund - regardless of whether the courier, a rough handling process, or simple bad luck actually caused the damage. The one narrow exception, set out directly in the same section, is a carrier the consumer themselves commissions to collect the goods, provided that carrier was not one the seller had already offered as an option - a genuinely rare arrangement in an ordinary eBay sale, where the seller is the one choosing and paying the courier throughout.

The gap that actually causes the real cost

The genuinely awkward part is not the law above - it is what happens next, between the seller and the courier. Many UK couriers' own terms specifically exclude glass, mirrors, and similarly fragile items from compensation, even in cases where the damage plainly happened while the parcel was in their possession. The result is a real, specific gap: a seller can be entirely correct to refund or replace a broken mirror under the law, and still have no route to recover that cost from the courier whose handling likely caused it in the first place. This is the actual "who pays" question worth understanding - not whether the buyer is owed a fix, which the law already answers, but who absorbs the cost once the courier's own terms decline to.

Why genuine packaging still matters, on both counts

Proper packaging for glass and mirrors - rigid double-wall boxes rather than single-wall, real corner protection, genuine cushioning rather than a token layer of paper - reduces how often a breakage happens in the first place, which matters regardless of who would technically be liable for a specific one. It also matters for the narrower, more transactional reason that some couriers will only consider a claim at all if the parcel meets their own stated packaging standard for fragile goods - a claim submitted for a mirror packed in a single thin box, even against a courier that does offer some fragile-item cover, can be declined on packaging grounds alone before the actual cause of the breakage is even considered.

What this actually looks like on a real courier's own published list

Checked 27 September 2026, directly against Evri's own list of what can and cannot be sent: glass items sit plainly under "excluded from compensation" - meaning they can genuinely still be sent, but Evri will not cover loss or damage to them at all. Worth knowing specifically for anyone reading this site: furniture itself appears on the very same excluded list, alongside glass, ceramics, and several other categories. This is not a hypothetical or a worst-case scenario being described for effect - it is one major UK courier's own current, published position, in its own words, for exactly the kind of goods a furniture dropshipper actually sends every day. It does not mean furniture cannot be sent through this courier, and it does not change the seller's own legal duty to the buyer covered above - it means the specific gap this piece describes, between what a seller owes a buyer and what a seller can recover from a courier, is not an edge case dreamed up for a blog post, but a real, current, named term a seller can check for themselves before choosing a courier for exactly this reason.

The honest pricing response

Given that a genuine breakage rate above zero is realistic for any category involving actual glass, the honest response is pricing that expects it rather than treating each occurrence as an unbudgeted surprise - much the same discipline already worth applying to postage cost generally. A small, realistic allowance for occasional breakage-driven refunds, built into the margin a mirror or glass-fronted item is priced at, is a more honest number than a margin calculated as if breakage will simply never happen.

Whether declaring an item "fragile" actually helps

Marking a parcel fragile can genuinely change how carefully a specific handler treats it day to day, and is worth doing regardless. It is worth being honest, though, that a fragile label is not itself a legal or contractual guarantee of anything - a courier's own exclusion for glass in its written terms applies whether or not the outside of the box says "fragile," and no amount of labelling turns an excluded item into a covered one. The label is a genuine, practical aid to careful handling; it is not a substitute for knowing what the courier's own terms actually say about the category being sent.

Why this is genuinely worth checking courier by courier, not assumed to be identical everywhere

Checked 27 September 2026, directly against Parcelforce's own page on items excluded from compensation: Parcelforce's domestic services include up to £150 compensation as standard, built into the price paid, before any specific item exclusions are even considered - a genuinely different starting position from a courier offering no inclusive compensation cover at all. This is worth knowing specifically because it means the honest answer to "does my courier cover glass" is never a single, universal fact about couriers in general - it is a specific term that varies between named services, some building in a baseline figure as standard and others excluding whole categories outright, and it is worth checking a specific courier's own current published terms directly before assuming either position by default.

A distinction worth being precise about: declared value versus actual cover

A related, easily-missed detail worth naming directly: even a courier that does offer some baseline compensation, rather than excluding a category outright, generally caps what it will actually pay out at a stated maximum figure per parcel, regardless of what the item inside genuinely cost or sold for. A higher-value mirror or glass-fronted cabinet sent through a service with, say, a £50 or £100 standard compensation ceiling is only ever covered up to that ceiling by default - the gap between that capped figure and the item's real value is a further, separate cost exposure worth knowing about honestly, distinct from the outright exclusion already covered above. Some couriers offer an additional, paid-for enhanced cover option specifically to close this exact gap for a higher-value item, worth checking directly against a specific courier's own current terms before assuming the standard, default cover is automatically sufficient for a genuinely valuable piece.

The practical habit worth building regardless of which courier is used

Since a courier's own decision on a claim often comes down to whether packaging met its stated standard, a genuinely useful habit is photographing the item packed, before it is sealed and handed over - the actual cushioning, the corner protection, the box itself - rather than relying on memory or a general sense that "it was packed properly" once a claim is already being disputed weeks later. This costs a few seconds per order and gives a seller real, dated evidence to submit alongside any claim, rather than an unsupported assertion the courier has no particular reason to accept over its own default position. The same photograph is equally useful if a buyer's own description of the damage looks inconsistent with how the item was actually sent - not to dispute a genuine breakage, but to have an honest, factual record either way rather than only the buyer's own account of what arrived.

A worked example

A mirror genuinely sold for £75.99, refunded in full after arriving cracked despite otherwise reasonable packaging: the seller is legally correct to refund the buyer immediately under the Consumer Rights Act, and separately submits a claim to the courier, only to have it declined under the courier's own glass exclusion. The £75.99 cost sits with the seller either way - the buyer was never in question, and the courier's own terms, not the law, are what determined whether that specific cost could be recovered afterwards. Knowing this in advance, rather than discovering it for the first time at the point of an actual claim, is the entire, practical difference between a manageable, priced-for cost absorbed calmly and a genuine, unplanned shock to that month's margin.

Where this stays worth checking directly

Sellhelm's own Products page keeps the real return percentage for a specific mirror or glass item visible against its actual price and fees - the same number genuinely worth checking honestly against a realistic breakage allowance built specifically for that category, rather than assuming the margin shown already accounts for a cost that, in practice, a specific courier's own terms may never actually cover.
