Amazon MCF Fees in the UK for 2026, by Size Tier and Units per Order

In brief: Amazon MCF fees in the UK are charged per item for orders that Amazon fulfils from your FBA stock but that were placed somewhere other than Amazon, such as your own website. The 2026 rates took effect on 29 May 2026, with an average rise of 3.5% per unit. A single-unit standard order starts at £3.40, and the price per item falls when an order holds two or more units. A fuel and logistics surcharge applies on top: 1.5% up to 18 November 2026, then 2% from 19 November 2026.

Size tier and weight	1 unit	2 units	3+ units
Light envelope, up to 20 g	£3.40	£2.64	£2.00
Standard envelope, up to 210 g	£3.43	£2.68	£2.00
Standard envelope, up to 460 g	£3.45	£2.69	£2.00
Large envelope, up to 960 g	£3.75	£2.70	£2.00
Small parcel, up to 150 g	£4.05	£3.11	£2.34
Small parcel, up to 400 g	£4.57	£3.41	£2.52
Small parcel, up to 900 g	£5.27	£4.14	£3.28
Small parcel, up to 3.9 kg	£8.12	£6.79	£5.62
Standard parcel, up to 400 g	£4.98	£3.74	£3.20

Amazon's table shows one rate for each oversize band. Small oversize costs £10.75 up to 760 g and £12.92 above it. Standard oversize light starts at £13.21 plus £0.93 per kg over 760 g. Heavy oversize starts at £46.04. Expedited delivery costs more: a single light envelope is £3.72 instead of £3.40. Amazon's page lists every weight band for both speeds.

How units per order change the price

Every item in an order is charged at the rate for that order's unit count, whatever its size tier. A two-unit order made up of a light envelope item and a heavy parcel item is charged at the two-unit rate for both.

The 2026 rise only touched single-unit orders for envelopes and parcels. Two-unit and three-plus orders kept their 2025 prices. Oversize rates went up for every order size.

A worked example

Illustrative figures. A seller's own website sends Amazon 500 MCF orders a month for a 350 g item in the small parcel tier, one unit each, by standard delivery.

• Fees before the surcharge: 500 × £4.57 = £2,285.
• With the 1.5% surcharge: £2,285 × 1.015 = £2,319.28.
• From 19 November, at 2%: £2,285 × 1.02 = £2,330.70, or £2,330.70 − £2,319.28 = £11.42 a month more.

Bundling changes more than the surcharge does. Two units in one order cost 2 × £3.41 = £6.82, against 2 × £4.57 = £9.14 as separate orders, a saving of £2.32 per pair.

What it means for your bookkeeping

• The cost belongs to another channel. MCF fees come off your Amazon balance, but the sale was made elsewhere. Post them to a fulfilment cost account for that channel, so your Amazon margin isn't understated and your website margin isn't overstated.
• VAT on the fee. MCF is an Amazon service fee, and UK fees have carried 20% UK VAT since August 2024. Take the VAT from Amazon's seller fee invoice. It is reclaimable if you're VAT-registered.
• Match fees to orders. The fee is charged per item at the order's unit rate, so check a few orders against the table when the rates change. Reimbursements for lost MCF items are capped; see MCF reimbursement caps.
• Track the surcharge. It is a percentage on top of each fee. The 2% surcharge article covers the dates. Compare with the UK FBA fulfilment fees for Amazon orders.

Do you need to do anything?

Check the units-per-order mix of your MCF orders. If many customers buy two items in separate orders, a bundle or a cart incentive on your own site could cut fees.
