The Amazon fee that matters this quarter is not the one everyone wrote about

Since Amazon confirmed a festive peak fulfilment fee for the UK, almost every write-up has led with the same figure: about 12p a unit. It is a real charge, it starts on 15 October, and for most sellers it is the smallest of the three things that changed.

The number that moved further is storage. From 1 October, a cubic foot of standard-size stock outside the clothing categories costs £1.51 a month instead of 76p. Sitting on top of that is a storage utilisation surcharge that reaches £2.29 a cubic foot for sellers holding more than a year of cover. Both are published in the same place as the peak fee, which is Amazon’s own FBA rate card.

Everything below is read off that rate card, the version effective 1 July 2026, and off Amazon’s own peak season post in Seller Central. Where a figure is widely repeated and wrong, we have said so and given the one the document actually prints.

What Amazon charges to store UK stock

UK storage is billed per cubic foot per month, on your average daily volume, and it has two seasonal bands. January to September is the cheap one. October to December is not, and the step up is far steeper for some categories than others.

One figure to be careful with. Older guides, including several still ranking, quote £1.37 for the October to December band on standard-size stock. The rate card effective 1 July 2026 prints £1.51. If you are modelling Q4 on the older number you are about ten per cent light, and that gap widens with every pallet.

The fee everyone wrote about, tier by tier

The festive peak fulfilment fee applies from 15 October 2026 to 14 January 2027. On 15 January 2027 fulfilment fees go back to the 2026 non-peak rates, which the rate card says are unchanged. Apparel is excluded, and so are oversize tiers and Low-Price FBA.

Here is what the uplift actually is, comparing the non-peak and peak columns for the UK on the same rate card. These are per unit sold.

So “12p a unit” is an average across a range that starts at zero. If you sell light items that ship in envelopes, the peak fulfilment fee does not touch you this quarter. If you sell standard parcels at the heavier end, it is 13p. Those are not the same planning problem, and an average hides both.

While we are correcting figures: the fuel and logistics surcharge that has applied to fulfilment fees since 17 April 2026 is 1.5 per cent, not the 3.5 per cent quoted in several places, and it applies to fulfilment fees rather than to storage.

The surcharge that can cost more than both

This is the part that is barely written about, and it is the one that can hurt most in January.

On top of the monthly storage fee, Amazon applies a storage utilisation surcharge. It is based on your storage utilisation ratio: your average daily inventory volume divided by your average daily shipped volume over the past 13 weeks. Read it as weeks of cover. The more stock you hold relative to what you actually ship, the higher the band.

Three exemptions are worth knowing, because they mean a lot of smaller sellers never see this at all. It does not apply to sellers whose first shipment to a fulfilment centre was less than 52 weeks ago, to Individual selling accounts, or to sellers holding less than 25 cubic feet of daily volume.

What it costs on one pallet of stock

A UK pallet stacked to about a metre and a half holds roughly 60 cubic feet. Here is the same volume of standard-size, non-clothing stock, priced four ways. The first three are Amazon’s published rates, the last is ours.

We are not going to pretend that is the whole picture, because it is not. The split is per SKU rather than per seller.

Leave it at Amazon when

• The SKU turns over in days, not months, so it never sits long enough to collect the Q4 rate
• It is apparel, or an envelope under 460g, which pay no peak fulfilment fee and a much softer storage step
• Losing the Prime badge on it would cost more than the storage ever could

Hold it elsewhere when

• It is slow stock, a long tail or a backup run that would sit through all three expensive months
• Your weeks of cover are climbing towards the surcharge bands
• You bought a container you cannot send in at once anyway, because of inbound limits

Amazon charges for the volume your stock occupies. We charge for the space you book. A half-empty box here still costs 85p a month, so the comparison above only holds if the pallet is reasonably well stacked. On a quarter-full pallet, Amazon’s way of measuring is the kinder one.

FBA storage buys the Prime badge and the Buy Box. Ours does not. If moving a bestseller out of FBA costs you the badge, the storage saving is irrelevant and you should not do it. This is the single most common mistake in this calculation.

Moving stock is not free. There is goods-in at our end, a shipment into Amazon at yours, and prep if the labels, bagging and box content information have to be right. The saving appears on stock that would otherwise sit at Amazon for weeks. It does not appear on stock that turns over in days.

You cannot leave it all outside and resupply at will in late November. Inbound delivery slots tighten through peak, and Amazon’s UK cut-off for Black Friday week is 28 October. Anything you plan to drip-feed has to be planned around that date, not around the day you run low.

The dates, in order

The storage band and the fulfilment fee are already set, so neither is a decision any more. The two that are still open are what you send in before 28 October and what you deliberately keep back, and they are the same decision looked at from both ends.

Where we sit on this

Our storage rates are on the published rate card: £18.00 a month for a pallet, 85p a month for a box of up to 60 by 40 by 40cm in bulk storage, and £2.10 a month for a pick bin on the picking shelf. Those rates do not change in October. The only uplift we charge on storage is on stock that has not moved for twelve months, at 50 per cent, and we tell you at nine months rather than letting it run quietly.

We do charge a peak surcharge, 20p per order in November and December, and it is on the rate card rather than buried in a contract. New clients get 30 days of free storage up to ten pallets, which is long enough to see whether any of this works for your SKUs before committing to it.

If the answer is to keep selling on Amazon but hold the slow stock elsewhere, that is FBA prep: we store it, and when you need it we label, bag and box it to Amazon’s requirements and send it in. If the answer is to run Amazon alongside your own shop, one pool of stock can cover both channels.

Amazon FBA storage costs, answered

When does Amazon’s 2026 festive peak fulfilment fee start and end in the UK?

It applies from 15 October 2026 to 14 January 2027. On 15 January 2027 fulfilment fees revert to the 2026 non-peak rates, which Amazon’s rate card says are unchanged. Apparel, oversize and Low-Price FBA items are excluded from it.

How much is the UK peak fulfilment fee per unit?

It depends entirely on the size tier, and the widely quoted 12p is an average of a range that starts at zero. On the rate card effective 1 July 2026, envelopes up to 460g pay no uplift at all, large and extra-large envelopes pay 7p more, small parcels pay 11p to 12p more and standard parcels pay 11p to 13p more. Oversize tiers pay nothing.

Do Amazon’s UK storage fees go up in Q4 2026, and by how much?

Yes, and by more than the fulfilment fee. For standard-size stock outside the clothing, eyewear, footwear and bags categories, UK storage goes from 76p per cubic foot per month in January to September to £1.51 in October to December. Clothing and the related categories go from 62p to 82p, and oversize from 55p to 87p. Older guides still quote £1.37 for that band; the current rate card says £1.51.

What is Amazon’s storage utilisation surcharge, and who pays it?

It is a second charge on top of the monthly storage fee, based on how much stock you hold against how much you ship, measured over the past 13 weeks and expressed in weeks of cover. In the UK it starts at 42p per cubic foot per month above 22 weeks of cover and reaches £2.29 above 52 weeks. It does not apply to sellers whose first shipment was less than 52 weeks ago, to Individual selling accounts, or to sellers holding less than 25 cubic feet of daily volume.

Is it cheaper to store Christmas stock at a 3PL than at Amazon?

On storage alone, usually yes, and the gap is wide in Q4: about 60 cubic feet of standard stock costs £90.60 a month at Amazon’s October to December rate against £18.00 a month for a pallet here. It stops being a saving once you add moving the stock in and out, and FBA storage buys the Prime badge while ours does not. The honest split is to leave fast-selling stock at Amazon and hold the slow stock elsewhere.
