Amazon's 2026 Peak Season Fees: What UK Resellers Need to Know and Do Now

Another Peak Season, Another Fee Hike

Amazon has confirmed that its "Peak Fulfilment Fees" are returning for the 2026 holiday period, this time with a second charge stacked on top. The announcement was made through Amazon's US Seller Central, so the figures quoted are in dollars, but the pattern matters just as much to UK sellers. Amazon has a long history of rolling out fee changes across its marketplaces on similar timelines, and anyone shipping stock into the US via Remote Fulfilment with FBA will feel these charges directly.

Even if you sell exclusively on Amazon.co.uk, this is worth reading closely. It gives you an early signal of how Amazon is thinking about costs heading into the busiest trading period of the year, and history suggests UK sellers shouldn't be surprised if a comparable surcharge structure appears closer to home.

What's Actually Changing

The fulfilment fee itself is holding steady compared with last year, working out to roughly 32 cents more per item on average during the peak window. What's new is the reintroduction of the 3.5% "fuel and logistics" surcharge, a charge Amazon first introduced back in April as a way to offset rising operating costs. Both charges now apply together during peak season.

Amazon has been upfront that these fees are aimed at sellers rather than shoppers directly, but as any experienced reseller knows, costs like this rarely stay contained to one side of the transaction. Some sellers choose to absorb the extra cost to stay competitive on price, while others build it into their listings and pass it on. Either way, it eats into margin unless you plan for it in advance.

The charges apply across several fulfilment methods, including standard Fulfilment by Amazon, Remote Fulfilment with FBA, Multi-Channel Fulfilment, and Buy with Prime. If you use any of these, assume the surcharge touches your account in some way during the peak window.

When Peak Season Actually Starts

According to Amazon, this year's peak fulfilment period runs from 15 October 2026 through to 14 January 2027, mirroring last year's dates. Sellers should expect the October fee changes to apply once shipments leave fulfilment centres on or after 15 October.

Amazon has also released a set of inventory deadlines that sellers should treat as hard cut-offs rather than suggestions:

Prime Big Deal Days

• 2 September: Amazon Warehousing and Distribution (AWD) shipments
• 9 September: FBA shipments using the "minimal shipment splits" option
• 16 September: FBA shipments using "Amazon-optimised shipment splits" (the option most sellers default to)

Black Friday Week and Cyber Monday

• 14 October: AWD shipments
• 21 October: FBA shipments using "minimal shipment splits"
• 28 October: FBA shipments using "Amazon-optimised shipment splits"

Amazon has been clear that fulfilment centre capacity gets prioritised for receiving stock in September and October, before shifting focus to processing customer orders in November and December. In practice, that means sellers who wait until the last minute risk lower capacity limits and stock arriving too late to qualify for peak promotions.

There's a Discount on the Table Too

It's not all extra cost. Amazon is bringing back its early submission discount for sellers who lock in deals ahead of schedule. Submitting Prime Big Deal Days offers by 5 August, or Black Friday Week and Cyber Monday deals by 5 September, saves £50-equivalent (quoted as $50 by Amazon) off the upfront promotion fee. It's a small saving in isolation, but combined with avoided capacity issues, planning early clearly pays off on more than one front.

How to Protect Your Margins This Peak Season

None of this is a reason to panic, but it is a reason to plan properly rather than reacting in November when it's too late to adjust. A few practical steps worth taking now:

1. Rework your product costings to include both the per-item fulfilment increase and the 3.5% surcharge, so you know your real margin before peak season hits rather than after.
2. Get stock into Amazon's network early. The deadlines above aren't arbitrary, missing them can mean your inventory arrives after the demand window has passed.
3. Decide your pricing strategy in advance. Are you absorbing the surcharge to stay competitive, or building it into your sell price? Make that call as a business decision, not a last-minute scramble.
4. Submit deals early where eligible to capture the promotion fee discount, since this is one of the few areas where being organised earns you money back rather than costing you more.
5. Watch for a UK equivalent announcement. Amazon has form for rolling similar surcharges out across marketplaces, so don't assume Amazon.co.uk will stay unaffected.

Where Lunar FBA Comes In

This is exactly the kind of shift where having a community and a set of tools around you pays off. Inside Lunar FBA, members flag fee changes, share how they're adjusting pricing, and compare notes on which products still stack up profitably once new surcharges are factored in. If you're using stock monitors and deal-sourcing tools to find opportunities ahead of peak season, now is the time to run your numbers through them again with the updated fee structure in mind.

Peak season can still be hugely profitable for UK resellers, but only if the maths is done properly before the stock goes in, not after the invoices land. Get your inventory timelines sorted, get your margins recalculated, and let the Lunar FBA community help you spot which lines are still worth backing this year.
