Last Mile Fulfilment: Models, Costs and How to Choose

TL;DR

• Last mile fulfilment covers everything between an order being placed and a parcel reaching the customer, including stock placement, picking, packing, dispatch, delivery and returns.

• Six fulfilment models are common in the UK, from central warehouses to ship from store and click and collect, and each trades speed, cost and complexity differently.

• Costs sit across storage, pick and pack, packaging, carrier fees, failed deliveries and returns, so judge every option on its all-in cost per order.

• The right choice depends on customer density, order profile, returns rate and stock accuracy, and most UK retailers end up blending two or three models.

• Software that allocates each order, plans routes and tracks every parcel in one view is what keeps a blended network profitable.

Picture a jacket ordered on a Sunday night in Leeds. The shop two streets from the customer has it on the rail. The order still ships from a warehouse 180 miles away, takes two days and arrives while nobody is home. That is a last mile fulfilment problem, and it drains margin quietly every day.

The pressure keeps building. The Office for National Statistics reports that 28.8% of retail sales in Great Britain were made online in August 2026. Online spending values were also 8.9% higher than a year earlier. Every one of those orders needs a stock point, a picker and a carrier.

This guide explains how the work fits together, compares the main fulfilment models, breaks down UK costs and shows you how to pick the right setup.

What Is Last Mile Fulfilment?

It is the full process of getting an order from a stock point near the customer into their hands, or into a collection point. It also covers anything that comes back. It starts when an order is allocated to a location and ends when delivery is proven, or the return is received.

It sits between two ideas that are easy to confuse. Order fulfilment covers receiving, picking and packing. Last mile delivery covers the final leg to the door. The wider process joins both and adds two decisions that belong to neither, which are where stock sits and which site serves each order.

Many US sources spell it last mile fulfillment, but the meaning is identical. Get those two decisions right, and delivery becomes shorter, cheaper and easier to promise. Get them wrong, and no carrier can fix the result.

How Last Mile Fulfilment Works

Every order passes through the same five stages, whichever model sits behind it.

• Stock placement. Inventory is positioned in warehouses, hubs, stores or small urban sites based on where customers actually live.

• Order allocation. The system chooses the site that should serve each order, weighing stock, distance, cut-off times, delivery promise and cost.

• Pick, pack and hand over. Warehouse or store teams prepare the parcel, then pass it to a carrier, a driver or the customer.

• Dispatch and delivery. Routes are built, drivers or carriers are assigned, and the customer receives an ETA.

• Tracking, exceptions and returns. Failed attempts, reschedules, collections and returns are handled and recorded.

The models below differ mainly in how they handle stages one and three. Retailers that sell through shops, websites and marketplaces often call the combined approach omnichannel fulfilment, because every channel draws on the same stock.

Last Mile Fulfilment Models Compared

These are the six setups UK retailers use most. Few run just one.

Central Warehouse Fulfilment

One or two large sites, often in the Midlands, serve the whole country. Handling cost per order is low, stock is easy to control, and picking is efficient at scale. The weakness is distance. Parcels travel further, same-day promises are hard to keep, and remote postcodes cost more to reach.

Best for. Steady demand, a spread-out customer base and a standard two or three day promise.

Last Mile Fulfilment Centre

This is a mid-sized site close to a large population cluster, such as London and the South East or the North West. It holds fast-moving lines and takes bulk stock from the central warehouse. It then ships next-day or same-day orders within its region. Stock is split across sites, so inventory planning gets harder.

Best for. Online brands whose orders cluster in a few city regions.

Micro Fulfilment

This model places small, often automated sites inside or beside stores and in urban units. These sites, including dark stores, pick fast-moving single-line orders within minutes. Grocers and convenience retailers lead the way. Set-up cost is high, and the model pays back only when order density and replenishment accuracy are both high.

Best for. Dense cities with a rapid promise on a narrow range.

Ship From Store

Ship from store treats stores as fulfilment nodes. An order is picked from the nearest shop and sent by courier or local driver. There is no new building, and slow-selling stock gets a second chance before markdown. The risks are inaccurate store stock and staff who are already busy serving shoppers.

Best for. Retailers with many high street or retail park stores, such as fashion, homeware and electricals.

Click and Collect and Lockers

Here the customer completes the last mile. Orders are collected from a store, a pickup point or a locker, and BOPIS has become a standard option in UK retail. Delivery costs fall and failed home deliveries disappear. Stores need pick space, collection slots and clear handover points.

Best for. Retailers with a store estate and shoppers who want flexible pick-up.

Outsourced and Hybrid Networks

Some retailers hand part of the work to 3PLs and carriers while keeping key regions or ranges in-house. This adds capacity for peaks and new regions without capital spend. The cost is less visibility, since each partner reports in its own format.

Best for. Fast-growing brands and multi-region retailers with seasonal peaks.

What Last Mile Fulfilment Costs in the UK

Cost per order is the number that matters, and it is built from several lines. Most UK orders carry the following.

• Storage. Charged per pallet, bin or cubic metre, and higher for slow-moving stock.

• Pick and pack. The labour to find, assemble and prepare each order.

• Packaging. Boxes, mailers and labels, sometimes bundled and sometimes billed separately.

• Carrier or driver cost. Billed by weight, size, zone and service level.

• Failed deliveries. Redelivery, customer contacts and lost goodwill, which add up as the cost of failed deliveries.

• Returns. Receiving, inspecting and restocking items that come back.

• Software and account fees. Warehouse systems, integrations and reporting.

UK benchmarks help you sense-check a quote. A pricing guide from UK provider Green Fulfilment, updated in September 2026, gives useful ranges. It puts pick and pack at £0.45 to £2.60 or more per order and storage at £10 to £30 per pallet per month. Returns handling runs £0.50 to £2.00 per item, and tracked parcels start from around £2.99. Carrier fees are usually the largest single line.

Labour sits behind most of these rates. The National Living Wage rose 4.1% to £12.71 an hour on 1 April 2026, so pick and pack rates face upward pressure at renewal.

Each model moves cost around. A central warehouse keeps handling low and pushes spend into carrier fees. Micro sites and store picking shorten the distance but add labour and inventory cost. Click and collect trims delivery spend and adds store workload. No model removes cost.

To calculate your own figure, add storage, pick and pack, packaging, carrier fees and an allowance for failed deliveries, returns and software. Then divide by orders shipped. Treat returns carefully, because reverse logistics can wipe out the savings from a cheap outbound route. A low pick fee can also hide a high storage charge, so check minimum volumes, peak surcharges and long-term storage fees before you sign.

How to Choose the Right Fulfilment Model

Work through these five questions before you compare sites or providers.

Customer Density and Delivery Promise

Map your orders by postcode first. If most come from London and the South East, a regional hub or micro site can serve them fast. If orders spread across Scotland, Wales and rural England, a central site with strong carrier cover may be enough. Highlands and Islands deliveries often carry surcharges. A same-day promise needs stock within a short drive of the customer.

Order Profile and Basket Size

Small single-line parcels suit micro sites and lockers. Multi-item baskets suit warehouses and stores with a deep range. Bulky goods need depots, larger vehicles and booked slots, so central sites or stores with delivery vehicles often work better.

Returns Rate

Fashion and footwear come back in high volumes. Returns to store through click and collect points can cut the cost of each one. Plan returns as part of the model from day one.

Stock Accuracy and SKU Spread

Store picking and micro sites depend on accurate, near real-time stock data. If store counts are unreliable, orders get accepted against stock that is not there. Wide ranges with many slow sellers fit a central warehouse, where one pool of stock serves everyone.

Build, Buy or Blend

The last question is who runs it. In-house logistics vs 3PL is a trade-off between control and capital. In-house gives you control of the customer experience but needs investment. A 3PL adds capacity quickly but reduces visibility.

Most UK retailers blend. A typical mix uses a central warehouse for the long tail, store picking in cities and a 3PL for peak. Start with one region or a small group of stores, prove the numbers, then expand.

Running a Blended Fulfilment Network With One Platform

A blended network creates a visibility problem. Stock sits in warehouses, stores and partner sites, and every carrier reports in its own format. Planners end up allocating orders by habit and chasing updates by phone.

Shipsy is an AI-native logistics platform that sits above those sites and carriers. It does not hold stock itself. It connects to major ecommerce platforms, ERP systems and existing TMS tools through APIs, so it can sit on top of what you already run. Here is what that looks like in practice.

• Order allocation. Omnichannel order allocation weighs inventory, proximity, delivery SLA and cost. It then picks the best fulfilment point, whether a store, a warehouse or a dark store, and the best carrier.

• Routing. A route optimisation engine handles 200+ constraints, selects the vehicle mix and plans store and customer delivery windows.

• Carriers. Multi-carrier management runs owned fleet and 3PLs on one platform and allocates by cost, SLA and capacity, with 240+ carrier integrations.

• Delivery. Last mile delivery software automates dispatch, live tracking and proof of delivery by photo, signature or barcode. Home, in-store and locker delivery run in one flow.

• Visibility and returns. Shipment tracking brings carrier updates into one view with predictive ETAs. Returns and failed-delivery handling sit in the same network as outbound delivery.

UK teams can also look at Shipsy’s transport management system in the UK, which covers planning, execution and tracking in one place.

Conclusion

There is no single best model. Central warehouses suit steady national demand. Regional hubs and micro sites bring speed to dense cities. Store picking puts existing shops to work, and click and collect trims delivery spend.

The right last mile fulfilment setup is the one that fits your customers’ postcodes and your all-in cost per order. Test each option on your own data, pilot in one region and expand once the numbers hold. When the network spans several sites and carriers, Shipsy gives you one platform to allocate orders, plan routes and track every parcel.
