How to choose a 3PL in the UK<\/h1>\n<\/div>\n\n\n

A third-party logistics provider (3PL) in the UK handles warehousing, pick and pack and shipping on a brand\u2019s behalf, so the one you choose directly affects your delivery accuracy, return rates and ability to scale. Knowing how to choose a 3PL matters before the sales calls begin and your decision needs to hold beyond your current order volume. Switching mid-growth is costly, especially if a previous 3PL has already let you down.<\/p>\n\n\n\n

This guide sets out the criteria experienced operators use to weigh up e-commerce fulfilment<\/a> services in the UK, not the ones sales teams lead with. If you\u2019re still deciding whether to outsource<\/a> at all, start there first.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

This guide sets out the criteria experienced operators use to weigh up e-commerce fulfilment<\/a> services in the UK, not the ones sales teams lead with. If you\u2019re still deciding whether to outsource at all<\/a>, start there first.<\/p>\n\n\n\n

1. Warehouse location and network<\/h2>\n\n\n\n

While the 3PL is the company operating your fulfilment, usually across several sites and carriers, a fulfilment centre is the physical warehouse. For UK brands, next-day delivery depends on holding stock in the UK, so location and volume of warehousing is the first thing to nail down. If European expansion is on your roadmap, ask whether the provider also has EU warehouse capacity<\/a> or a proven partner network, since shipping every EU order<\/a> from the UK now means customs admin and slower delivery. Be cautious of inventory spread thinly across lots of small sites too: it adds complexity for little benefit. At the scale most growing brands operate, one primary site with regional overflow is usually easier to manage and easier to forecast against.<\/p>\n\n\n\n

2. Platform integrations<\/h2>\n\n\n\n

Direct integrations with Shopify, Amazon, Magento and eBay are a given now, not a differentiator, so the real question is how they\u2019re built. Syncing orders manually between your store and a 3PL adds unnecessary risk and takes up valuable staff time, which is why it\u2019s worth asking exactly which integrations are native and update in real time, and which lean on middleware or a scheduled export. As a rule, the fewer moving parts between checkout and the warehouse floor, the fewer points at which an order can fail. For premium brands, an order that needs a gift message or branded insert should reach the warehouse floor with that instruction attached, not lost in a nightly export.<\/p>\n\n\n\n

3. Peak capacity and Q4 planning<\/h2>\n\n\n\n

What happens in November? A 3PL that processes orders comfortably in July can still buckle under Black Friday and Christmas volume. Get documented capacity commitments for peak and a concrete account of how they coped in previous Q4 periods. Vague answers here are a red flag; what you want are numbers: how many extra staff they take on, where their throughput ceiling sits and whether your SLA still holds when volume triples. A provider handling 500 orders a day in spring won\u2019t automatically manage 5,000 a day at peak.<\/p>\n\n\n\n

4. Pick and pack accuracy<\/h2>\n\n\n\n

Pick and pack accuracy is one of the few measurable indicators of operational quality a 3PL will share before you sign, so ask for their accuracy rate and whether it\u2019s written into the contract. The strongest providers will put an accuracy SLA in the contract rather than talk in vague ranges: International Logistics Group (ILG), for example, commits to a pick accuracy SLA of 99.5%, with real-world performance higher. Anything offered as an approximate range rather than a firm number should prompt a closer look at their QA process.<\/p>\n\n\n\n

5. Returns management<\/h2>\n\n\n\n

Returns are part of the customer experience, not just a cost line. Does the 3PL process returns in-house or outsource them to a third party? What is the turnaround from receipt to restocking? Can they handle grading and repackaging for premium products? Brands in beauty, fashion and wellness have specific requirements around returns condition assessment that a generalist 3PL may not meet. At ILG, that assessment follows condition rules agreed with each client up front: as-new goods go back into live, sellable stock; items with a recoverable issue such as damaged outer packaging are repacked or refurbished to a sellable standard; and anything used, damaged beyond repack or hygiene-compromised is quarantined and handled to the client’s instruction. For beauty and wellness the seal is a hard line, an opened or tamper-compromised product never re-enters sellable stock, however it looks.<\/p>\n\n\n\n

6. Visibility and reporting<\/h2>\n\n\n\n

You should be able to see your stock in real time without paying extra for the privilege, so before you sign, ask for a live demo of the client portal and confirm exactly what you\u2019ll see: stock levels, order status, returns and SLA performance. As a simple benchmark, you should be able to check your live stock at 11pm on a Sunday without emailing anyone. It matters because poor visibility is the complaint brands raise most often after a switch and it\u2019s the one that almost never comes up in the sales conversation.<\/p>\n\n\n\n

7. Category experience and account management<\/h2>\n\n\n\n

A 3PL specialising in generic B2C parcels may not fit a premium beauty brand with fragile packaging, or a subscription brand with complex kitting. Check their experience in your category, then find out who your named account manager will be and what their background is: the best providers assign someone who understands your commercial context, not only your operational one. If the answer is \u2018a team\u2019 or \u2018the support desk,\u2019 keep pushing. At ILG, every account has a named Corporate Account Manager who owns the relationship and answers for how it performs, backed by an Account Director for seniority and continuity. The point is simple: your named contact should be an accountable individual who knows your account, not a shared mailbox.<\/p>\n\n\n\n

Red flags to watch for<\/h2>\n\n\n\n

When you\u2019re choosing a 3PL provider, these are the warning signs worth walking away from:<\/h3>\n\n\n\n
