How Much Do 3PL Fulfilment Services Cost in the UK?

Cost is rarely a single number with 3PL fulfilment in the UK. It is a bundle of charges that reflect space, labour, carrier rates, and the way your operation behaves day to day. Two brands shipping the same number of orders can pay very different totals because their products, order profiles, and service promises pull the cost model in different directions.

Most UK 3PLs price fulfilment on a menu basis: you pay for onboarding, inbound receiving, storage, pick and pack, packaging, shipping, and returns, with optional extras for value added work. What matters is the blended cost per order once everything that genuinely applies to your business is included.

What you are really paying for

A fulfilment partner is selling three things at once: capacity, consistency, and speed. Capacity is the warehouse space and labour that flexes with demand. Consistency is the process discipline that protects accuracy and brand reputation. Speed is how quickly orders leave the building, with cut off times and weekend services often carrying a premium.

Because of that, “cheap” and “cost effective” are not the same idea. A lower pick fee can be outweighed by high storage, rigid minimums, expensive packaging, or slow dispatch that forces you into pricier shipping methods.

Typical cost ranges in the UK (2026 snapshot)

The numbers below are indicative ranges seen across UK providers serving ecommerce and omnichannel brands. Your exact quote will depend on volume, SKU characteristics, handling complexity, and location.

Cost component	How it is commonly charged	Typical UK range (GBP, ex VAT)	What pushes it up
Onboarding and setup	One off project fee	£0 to £2,500+	Complex integrations, process design, bespoke reporting
Inbound receiving	Per pallet, carton, or unit	£5 to £20 per pallet, or £0.15 to £0.60 per unit	Manual counting, mixed pallets, quality checks
Storage (pallet)	Per pallet per week or month	£3 to £8 per pallet per week	Oversize pallets, seasonal peaks, racking type
Storage (bin/shelf)	Per bin/tote/sqm	£0.50 to £3 per bin per week	Small item density, secure cages
Pick and pack (single item)	Per order plus per item	£1.20 to £3.50 per order	Tight cut offs, fragile handling, branded presentation
Additional items (multi line)	Per extra line or unit	£0.20 to £1.20 each	High SKU count, lot control, serialisation
Packaging materials	Per parcel	£0.10 to £1.50+	Custom boxes, inserts, void fill, tape branding
Shipping labels and carrier admin	Per parcel	£0.05 to £0.25	Multi carrier routing, special services
Domestic shipping (UK)	Carrier pass through or mark up	£2.50 to £6.50+	Oversize, remote areas, 24 hour or timed delivery
Returns processing	Per returned order or item	£1.50 to £6.00	Testing, repack, refurbishment, restocking rules
Value added services	Per unit or per hour	£25 to £60 per labour hour	Kitting, bundling, customisation, QC checks

These ranges are useful for modelling, yet the best predictor of your cost is the shape of your orders: average items per order, average weight and dimensions, and the share of orders requiring special handling.

The main fee categories, explained

A 3PL quote usually looks like a list of line items. To translate that into a decision, it helps to see what each one really means in practice.

After reviewing what typically appears on proposals, most charges fall into a handful of buckets:

• Receiving and putaway: booking in stock, checking counts, and moving it to storage
• Storage: the space your inventory occupies, plus the opportunity cost of keeping it available
• Order processing: picking, packing, labels, paperwork, and dispatch scans
• Transport: carrier charges for delivery, surcharges, and service levels
• Reverse logistics: returns, exchanges, inspections, and restocking

That list looks simple, yet each bucket hides details that can shift the total by a meaningful margin.

Setup and onboarding: the cost of getting it right

Some 3PLs waive onboarding to win business, then rely on ongoing fees and minimums. Others charge a clear one off fee that covers integration, warehouse training, barcode rules, and test orders. Neither approach is inherently better; what matters is whether the setup work is genuinely done.

Onboarding costs rise when you need custom packing flows, multiple sales channels, or compliance steps like batch tracking, expiry management, or serial number capture. A strong onboarding plan can save money later by reducing mispicks, eliminating manual work, and avoiding “special case” handling that slows the warehouse down.

Receiving and inbound handling: where accuracy starts

Inbound fees tend to be modest compared to shipping, yet they influence accuracy and stock availability. Expect either per pallet, per carton, or per unit pricing, sometimes with a time allowance.

Receiving gets more expensive when deliveries are poorly labelled, mixed, or arrive without accurate advance shipping notices. If your purchase orders often change at short notice, ask how the 3PL handles exceptions and whether you pay for recounts.

Storage pricing: pallets, bins, and the hidden cost of slow movers

Storage is commonly charged per pallet position per week, or per bin/tote for small items. Some operators charge per cubic metre, which can be fair for bulky goods but harder to forecast.

A key commercial detail is how “idle” inventory is treated. If you hold large quantities that turn slowly, storage can overtake pick and pack as the dominant cost. That is not a failure of the 3PL model; it is a signal to tune purchasing, promotions, or replenishment cadence so the warehouse works as a flow system rather than a long term holding area.

When comparing storage quotes, check for:

• Whether pricing changes at peak season
• Whether there are minimum pallet counts or minimum spend rules
• How they treat oversize products and non standard pallets

Pick and pack: the line items that look small but add up

Most UK fulfilment pricing includes a base pick fee (sometimes called “first pick”) and an incremental fee for extra items or extra lines. A “line” is usually one SKU, regardless of quantity, though providers vary.

The right way to judge pick and pack is to model your real order profile. If your average order contains 2.8 items across 1.6 lines, a cheap single item rate is less relevant than the blended cost across the full basket.

To keep comparisons honest, ask each 3PL to price the same sample set of orders from your recent history. Ten to twenty representative orders can surface the true economics faster than a glossy rate card.

Packaging: brand experience versus unit cost

Basic packaging is often charged per parcel, with materials either included up to a limit or billed separately. The cost can be low for plain mailers and standard cartons, then rise for fragile packs, high void fill usage, or custom branded presentation.

If brand presentation matters, make it explicit early. The fulfilment floor works best with standardised packs. You can still create a premium unboxing, yet it needs disciplined pack rules, reliable supply of inserts, and clear acceptance criteria so the team can move quickly without guesswork.

Shipping: the biggest variable on most invoices

Carrier costs often dominate the bill, and they are the hardest to compare because each 3PL has different carrier mix, discount tiers, and surcharge handling. Some pass carrier charges through at cost, some apply a mark up, and some bundle shipping into an all in per order price.

Shipping costs rise quickly with:

• Volumetric weight and oversize parcels
• Remote area and Highlands surcharges
• Signed for, age verification, or timed services
• Battery handling, aerosols, and other restricted goods

A useful practice is to request a “rate card plus surcharge rules” summary, then run it against your last month of shipments by weight band and postcode zone. It turns the conversation from opinion to arithmetic.

Returns: the quiet cost centre

Returns pricing is often overlooked during selection, then becomes painful once you scale. The fee is usually per returned order or per item, with extra charges for testing, repacking, steaming, refurbishment, or disposal.

Returns cost is not only a warehouse issue. It is also a product, merchandising, and customer expectations issue. Clear size guides, strong product photography, and better packaging can reduce return rates and the damage rate, which cuts cost and improves resale value.

Minimums, retainers, and “all in” pricing

Many 3PLs operate with minimum monthly spend, especially for smaller brands. This can be framed as a retainer, a minimum number of orders, or a minimum storage charge. It is not automatically negative. It can be the mechanism that reserves labour and space so service levels stay reliable.

All in pricing, where a single fee covers pick, pack, and standard packaging, can make budgeting easier. The risk is that it hides the cost drivers that you could otherwise manage. If you expect product mix or order profile to change, transparency often wins.

A simple way to estimate your blended cost per order

To get to a working budget, you need one number: expected fulfilment cost per dispatched order, inclusive of the fees that genuinely apply. A practical method is:

1. Calculate your expected monthly orders and average items per order.
2. Estimate monthly storage based on average pallets or bins held.
3. Add packaging and shipping based on parcel size and service level mix.
4. Add expected returns cost based on your return rate.
5. Add any minimum spend adjustment.

Once you have the blended number, you can compare it to your gross margin per order and set a realistic free delivery threshold.

Example scenarios: what brands often see in practice

A small, lightweight DTC brand shipping letterbox parcels will often find that pick and pack plus packaging is the main controllable cost, while shipping is relatively stable. Their biggest wins come from reducing touches, standardising pack rules, and keeping SKUs tidy so pick speed stays high.

A heavier, bulky goods seller sees shipping and storage dominate. Here, carton optimisation, tighter replenishment, and regional carrier selection can matter more than shaving pennies off the pick fee.

A brand with complex kits and bundles may pay more per order, yet can still achieve strong unit economics because the 3PL replaces in house labour, reduces errors, and supports faster cut off times that lift conversion.

Questions that keep costs predictable

Contracts and rate cards do not prevent surprises; clarity does. Before you sign, push for plain answers on the areas that typically create invoice shock:

• Rate triggers: what events create extra charges and how they are measured
• Peak policy: how pricing and cut off times change during high season
• Error handling: who pays when something goes wrong, and how disputes are resolved
• Data and reporting: what is included, what is paid, and how quickly you can access it
• Exit terms: how stock is returned, what it costs, and the notice period required

A good 3PL relationship is built on shared visibility. When both sides can see the drivers of cost and performance, you can tune operations over time, protect your customer promise, and scale with confidence.
