How to find a manufacturer: a UK buyer's guide

Write the specification first

The most common mistake is to start searching before you know exactly what you are asking for. Manufacturers quote against what you send them. A vague brief produces quotes that cannot be compared and samples that miss the point.

A useful specification covers:

• drawings or reference samples, with dimensions and tolerances
• materials, finishes and colours, with acceptable alternatives
• performance, safety and certification requirements for the UK market
• packaging, labelling and carton requirements
• annual volumes, typical order sizes and target delivery dates
• the quality standard and how goods will be inspected

It does not need to be long, but it does need to be the same document for every supplier you approach. That is what makes the quotes comparable.

UK or overseas

Before searching, decide where to look. Overseas manufacturers can offer lower unit prices and capabilities that are hard to find in the UK. UK and near-shore suppliers offer shorter lead times, smaller minimum orders, easier quality control and less cash tied up in stock at sea.

The right answer depends on the product. High-volume, stable products with low freight cost relative to value often suit overseas manufacture. Bulky products, fast changing ranges and products where quality failures are expensive often suit a nearer supplier. The only fair comparison is on landed cost, covered below.

Where to search

No single source gives a complete list. Use several and cross-check what you find.

Trade data. Import and export records show which overseas companies ship which products, and to whom. Commercial trade data services can show who supplies your competitors and the volumes involved. This is one of the best ways to find manufacturers that genuinely make your product at scale.

Trade fairs. Industry exhibitions, in the UK and in manufacturing countries, let you meet many suppliers in a few days, handle samples and judge how a company presents itself. Follow up with a site visit before committing: a stand tells you little about a factory.

Trade associations. Industry bodies often hold member directories and can introduce you to manufacturers that do not advertise widely. In the UK, they are a good route to specialist and smaller manufacturers.

Online marketplaces and directories. Business-to-business marketplaces make it quick to build a long list and request quotes. Their limits matter, though. Listings are written by the sellers, many are trading companies rather than factories, and badges or verification labels describe what the platform has checked, which may be less than you assume. Use them for leads, then verify independently.

Referrals. Non-competing businesses, freight forwarders, testing laboratories and inspection companies all see many suppliers. A recommendation from someone who has shipped with a manufacturer is worth more than any listing.

Factory or trading company

Many suppliers that present themselves as manufacturers are trading companies that buy from factories and resell. That is not necessarily a problem: a good trading company can consolidate products, manage several factories and take on small orders. But you should know which one you are dealing with, because it affects price, control and how much you can find out about where your goods are made.

• Ask for the business licence and check the registered scope of business.
• Ask to visit the production site, and check that the address matches.
• Ask which processes are done in-house and which are subcontracted.
• Look at the range offered: an unusually wide range suggests a trader.
• Ask for the names of the machines and lines used for your product.

Samples, audits and references

Once you have a shortlist, test what each supplier says.

Samples. Request samples made to your specification, not catalogue items. Test them against the specification and record the results. Keep an approved sample as the reference for production.

Audits. A factory audit checks that the site exists, has the capability and capacity it claims, and meets basic standards on quality systems, labour and safety. For overseas suppliers, an audit by an independent in-country partner is far more reliable than photographs or a video call.

References. Ask for customers you can speak to, ideally in the UK or Europe and buying similar products. Ask about quality, communication and how problems were handled, not just whether they are happy.

Before the first shipment, arrange an independent pre-shipment inspection. It is the last point at which a problem can be fixed cheaply.

Comparing on landed cost

Unit price is only the start. Compare shortlisted manufacturers on landed cost: the supplier price plus freight, insurance, duty and the charges between the port and your door. Add the less visible costs too: minimum order quantities, payment terms, lead time and the stock you will need to hold.

Our landed cost calculator gives a quick estimate for each option, so you can see whether a lower overseas price survives the journey.

When to use a sourcing agent or consultant

You can find a manufacturer yourself, and many businesses do. Outside help makes sense when you lack time, in-country knowledge or language skills, when the product is technically complex, or when the cost of getting it wrong is high.

If you use outside help, ask three questions before you start. How are you paid, and does any factory pay you anything? Will I see the factory's own quotes? Who owns the relationship with the supplier if we stop working together? The answers tell you whose interest the agent or consultant serves.

Negotiating and placing the first order

Once you have chosen a manufacturer, agree the terms before production starts, and put them in writing. The points that cause most disputes later are the ones left vague at the start.

• price, currency and the Incoterm, so it is clear who pays for freight and when risk passes
• payment terms, including any deposit and what must happen before the balance is paid
• the approved sample and specification as the quality reference
• inspection rights and what happens if goods fail inspection
• lead times, and what happens if they are missed
• ownership of tooling, moulds and designs paid for by you
• confidentiality and protection of your designs

Start with a smaller first order if you can. It tests the manufacturer's production, packing and communication at lower risk, and gives you real data on lead time and landed cost before you commit larger volumes.

Keep more than one option open. Even when one manufacturer becomes your main supplier, a qualified alternative protects you if quality slips, prices rise or capacity is taken by a larger customer. Review the relationship at least once a year against the original specification, landed cost and service.
