Swimwear manufacturers in the UK are a small group, and the most useful thing to know about them is where each one actually sews. Some make in Britain, some make in Britain and abroad, and some businesses that appear in UK searches make overseas. This guide names the swimwear makers we checked in November 2026 on their own websites and on Companies House, what each publishes about minimums and lead times, why wired styles usually go abroad, and what duty applies when they do.
Swimwear is also one of the hardest categories to make well. Most of what goes wrong (sagging, see-through fabric when wet, elastic that cuts or gapes) is invisible on a dry sample. So the second half of this guide covers the technical questions to ask before you pay for production.
Heads up: We're UK Clothing Factory, a group of documented clothing factories in the United Kingdom. The companies named below are independent businesses, checked on their own websites and on Companies House in November 2026, and are not members of our group. Our role is separate: our team replies to your brief within 24 hours, then places and manages your production with the factory in our group built for your product, from 100 pieces per style.
Key Takeaways
- Apparel Inspired (production unit on the North East coast) publishes swimwear minimums of 50 to 100 pieces per style and says wired designs go to a specialised overseas partner (Apparel Inspired).
- The London Pattern Cutter (Greenwich) says all its production is in London, with flatlock and coverstitch machines and no minimum order quantities (The London Pattern Cutter).
- A London address is not a UK origin. Ro & Ritzy lists a London office and an Ahmedabad address and describes itself as a factory importing swimwear fabric into India (Ro & Ritzy).
- Duty if you make abroad: 12% on most synthetic swimwear under the UK Global Tariff, or 0% from partners such as the EU, Turkey and India when the rules of origin are met (UK Trade Tariff).
- Test wet, in daylight, before you approve. Wet fit, opacity and elastic tension decide whether a swimsuit works.

Which UK manufacturers make swimwear?
Three businesses that offer swimwear production to UK brands publish enough about themselves to check. Two say they make in Britain; the third makes in India. We describe each from its own website and its Companies House record, read on 3 November 2026.
Apparel Inspired (Harrogate design office, North East production unit)
Apparel Inspired says it offers swimwear manufacturing in the UK for brands that want non-wired swimwear for men, women and children: bikinis, one-piece costumes, swim shorts, board shorts and rash vests, with fashion swimsuits and tankinis also listed. It quotes minimums starting at 50 to 100 pieces per style depending on the product, and its production section lists minimums of 50 pieces and capacity of up to 3,000 pieces per month (Apparel Inspired, swimwear).
Its design office and showroom are in Harrogate and its production unit is on the North East coast of England, with a Hartlepool address on the website (Apparel Inspired, British clothing factory). The company is APPAREL INSPIRED LTD, 14901020, active, incorporated in May 2023 and registered in Harrogate. Its registered nature of business is specialised design activities, which is a reason to ask which work happens in its own unit and which it places elsewhere.
Two lines on the site matter for planning. For wired designs, it says it sources and manages production with a specialised overseas partner. And more generally it says it can manufacture in the UK and overseas, depending on the client's needs. That openness is useful: it tells you to confirm in writing which applies to your order before you plan a "made in UK" label around it.
The London Pattern Cutter (Greenwich, London)
The London Pattern Cutter is a pattern-cutting and development studio in the Telegraph Building on Harrington Way, Greenwich (contact page). Its swimwear page says that all its production is in London, that it has a fully equipped swimwear sampling and manufacturing unit, and that it has flatlock and coverstitch machines. It offers swimwear design, pattern cutting, grading, tech packs, fabric and trim sourcing, sampling and production runs, and says it works with no minimum order quantities (The London Pattern Cutter, swimwear).
It also publishes lead times: on average 2 to 6 weeks per sampling round and 4 to 12 weeks for production, depending on the project. And it answers a question many brands forget to ask: because it charges for patterns and samples, the patterns it makes belong to the client.
One gap to close before you pay: the website does not name a legal entity, and we found no company on Companies House under that name. That is not unusual for a trading name, but ask which company will invoice you and check its number before you commit money.
Citation capsule: Apparel Inspired Ltd (Companies House 14901020, active) publishes UK swimwear minimums of 50 to 100 pieces per style, capacity of up to 3,000 pieces a month, and says wired designs are made with a specialised overseas partner. The London Pattern Cutter in Greenwich says all its production is in London, with flatlock and coverstitch machines, no minimum order quantities, 2 to 6 weeks per sampling round and 4 to 12 weeks for production.

Which UK-facing swimwear maker produces in India?
Ro & Ritzy markets itself to UK brands: its swimwear page is titled "Sustainable Swimwear Manufacturers UK". It offers custom and private label swimwear, including bikinis, one-piece swimsuits and high-waisted bottoms, in fabrics such as Carvico and ECONYL regenerated nylon. Its contact section lists a UK address at 128 City Road, London EC1V and an Indian address in Sumel Business Park, Ahmedabad (Ro & Ritzy, sustainable swimwear).
The production location is clear from its own words: it describes itself as a factory with an import and export licence, which lets it import swimwear fabric into India from Italy or the US duty-free for the clients of its factory. The UK company, RO AND RITZY APPAREL LTD, 13822565, is active, was incorporated in December 2021 and has its registered office at the same City Road address.
Its published terms are some of the most detailed in this category. Custom swimwear starts from 50 pieces per design, or 100 on some premium fabrics. For its ready-made designs, the minimum is 50 to 100 per order with 10 to 20 per style and colour, samples have no minimum and take 3 to 7 days on in-stock fabric, and main orders take 4 to 8 weeks. Its FAQ gives 1 to 4 weeks for sampling on custom work.
There is nothing improper about any of this, and the company publishes it plainly. It simply means a garment made there cannot carry a UK origin claim, and it is the clearest example of why a London postcode does not answer the origin question.
How do UK swimwear manufacturers compare?
| Business | Where it sews | Minimum | Lead times published | Companies House |
|---|---|---|---|---|
| Apparel Inspired | UK production unit (North East); overseas partner for wired; UK or overseas by requirement | 50 to 100 per style | Not published | 14901020, active |
| The London Pattern Cutter | All production in London (Greenwich) | No minimum stated | Sampling 2 to 6 weeks per round; production 4 to 12 weeks | No company found under this name; ask |
| Ro & Ritzy | India (Ahmedabad); London office | 50 per design (100 on some fabrics) | Samples 3 to 7 days (stock fabric); bulk 4 to 8 weeks | 13822565, active |

Three businesses, three different answers to the origin question: all in London, UK or overseas depending on the order, and India. That is why the "where it sews" column comes first. It matters legally as well as for your brand story: a product's origin is where it was last substantially transformed, and Make It British's guide to the rules uses the example of fabric stitched into garments in Leicester counting as UK-made, while ready-made garments printed in the UK do not (Make It British). A swimsuit sewn abroad and only finished, labelled or packed here is not UK-made.
Why do wired swimwear styles go overseas?
Because wired construction is a specialism within a specialism. A wired cup is a structural assembly: the wire has to sit in a channel that stops it moving or breaking through, the cup needs moulding or panelling that keeps its shape when wet, and the underband carries the load. The same is true of underwired lingerie, which is why the factories that do it well tend to be bra and swim specialists.
Grading is the other half. In a bra-sized range, the underband and the cup move independently: a 34C and a 36C have different underbands, while a 34C and a 34D share an underband and differ in cup. A factory that grades swimwear like ordinary apparel, by stepping every measurement up together, will produce a range in which one size fits and the rest fit approximately.
So a UK maker that sends wired work to a specialist partner, as Apparel Inspired says it does, is making a technical call, not dodging the question. For a brand, the practical point is to decide early whether wired styles belong in a first collection. Unwired, soft-cup and bandeau styles can be made in Britain by the makers above. Adding wired styles usually means a second supplier, a second origin and a second lead time.
A first range that stays unwired keeps everything in one factory, under one origin claim, with one set of samples to approve. Wired styles can follow once the fit of the core range is proven.
What makes swimwear technically difficult?
Four things, and none of them shows in a photograph of a finished garment.
- Chlorine, salt and sun cream attack elastane. Swim fabric is built to resist them. Colour fastness to pool water is tested under EN ISO 105-E03, which treats fabric with active chlorine at concentrations used to disinfect swimming pools; it names 50 and 100 mg/l as the levels intended for swimwear (EN ISO 105-E03). Fibre makers also sell more resistant elastane: Lycra says its XTRA LIFE fibre lasts up to 10 times longer than unprotected spandex, based on laboratory and pool tests (Lycra). Ask your maker which fibre the fabric uses and for its test results.
- Wet fit is not dry fit. Stretch fabric relaxes when wet, so a swimsuit fitted only on a dry body can be looser in the water than intended. A sample approval that has not involved water is incomplete.
- Elastic is structural. Leg openings, necklines and underbands are held by elastic that has to be specified by width, type and how it is applied, and sewn at the right tension. Too loose and the garment gapes; too tight and it cuts. This is where flatlock and coverstitch machines, and the people who run them, earn their place.
- Linings and opacity. A swimsuit must not turn see-through when wet. That depends on fabric weight, lining and colour, and pale colours are harder than dark ones. Test it wet, in daylight, before approving anything.
A factory-ready tech pack for swimwear needs the fabric composition, the elastic specification for each opening, the lining detail, and measurements both relaxed and stretched. Our how we work page explains where that fits in a production brief.
Citation capsule: Swimwear has four technical risks that a photograph cannot show: elastane damage from chlorine, salt and sun cream; fabric that relaxes when wet; elastic at the leg, neck and underband that must be applied at a specified tension; and opacity when wet. EN ISO 105-E03 tests colour fastness to chlorinated pool water at 50 and 100 mg/l active chlorine for swimwear.
Can a small brand make swimwear in Britain?
Yes, if the range is unwired and kept narrow. The makers above publish minimums from none at all (The London Pattern Cutter) to 50 to 100 pieces per style (Apparel Inspired), so a first run of one or two styles is realistic in Britain. One silhouette, one or two colourways, unwired: that brief suits a UK maker and keeps development costs from swallowing the production budget.
The fabric is the tighter constraint. Performance swim fabric is a technical textile, often bought from a mill in minimums per colour, and prints add their own set-up on top. A brand planning four prints across two styles is planning a fabric buy that can dominate the whole project.
Spend on sampling instead. Wet fit, opacity and elastic tension all have to be tested on a physical garment, and each round teaches you something the last one could not. With 2 to 6 weeks per round at one London maker, two or three rounds can take most of a season, so start the development well ahead of the date you want stock.
A realistic plan for a first collection: one silhouette, two colourways, unwired, tested wet, produced at the maker's minimum. Add prints and wired styles once the fit is proven and sales can fund a second supplier.
What does swimwear fabric really cost you?
More than the price per metre suggests, for three reasons that add up in a small collection.
- Swim fabric is engineered. A chlorine-resistant, high-stretch, colour-fast knit is a technical product, and fewer mills make it than make plain jersey. Ro & Ritzy, for example, names the Italian mills Carvico and Jersey Lomellina as the fabrics its clients prefer.
- Minimums apply per colour, and prints carry a set-up. A plain colourway is a dye lot; a print is a dye lot plus a print set-up. Digital printing is cheap to set up and dearer per metre; rotary printing is the reverse. Ask your fabric supplier for both prices before you commit to a print count.
- The lining is a second fabric. Most swimwear is lined, and the lining has its own minimum. It is not a large cost per garment, but it is a second fabric order to plan.
The lever that works is the one brands resist most: reduce the number of fabrics before you reduce the number of garments. Two colourways of one engineered fabric is a workable first collection. Four prints across two fabrics is a large fabric bill with a few swimsuits attached.
One way round mill minimums is stock fabric. Some makers hold a limited palette in stock, and choosing from it removes the mill minimum: Ro & Ritzy, for instance, offers samples with no minimum on in-stock fabric, although it produces in India. You choose from what exists rather than what you drew, and for a first collection that trade can be worth making.
What import duty applies if your swimwear is made abroad?
If you place swimwear outside the UK, duty is part of the landed cost. Under the UK Global Tariff, women's or girls' swimwear of synthetic fibres (6112 41 90) and men's or boys' swimwear of synthetic fibres (6112 31 90) carry a 12% third-country duty, women's synthetic swimwear containing 5% or more by weight of rubber thread (6112 41 10) carries 8%, and woven swimwear under 6211 11 and 6211 12 carries 12% (UK Trade Tariff, 6112 41 90; 6112 41 10).
Trade agreements can bring that to 0%. The tariff lists preferential rates of 0% for swimwear from the EU, Turkey, Vietnam and other partners, and for India since the UK-India trade agreement entered into force on 15 July 2026 (GOV.UK). Countries under the Developing Countries Trading Scheme pay 9.6% at the standard rate and 0% under the comprehensive and enhanced preferences.
The 0% rate is not automatic. Each agreement has its own rule of origin for knitted garments. Under the UK-EU agreement, a swimsuit sewn from cut knitted pieces must combine knitting with making-up, including cutting. Under the UK-India agreement the rule for the same garment is knitting and making-up, including cutting. Read literally, a swimsuit sewn in India from fabric knitted in Italy does not meet the India rule, so it could pay the full 12%. The agreements have tolerances and other provisions, so check your own product with a customs adviser before you rely on the 0% rate.
Citation capsule: Under the UK Global Tariff, synthetic swimwear (6112 41 90 and 6112 31 90) carries 12% duty and women's synthetic swimwear with 5% or more rubber thread (6112 41 10) carries 8%. Swimwear from the EU, Turkey, Vietnam and, since 15 July 2026, India can enter at 0% when it meets the rules of origin, which for knitted garments generally require both knitting and making-up in the partner country, subject to each agreement's tolerance and cumulation rules.
How do you verify a UK swimwear manufacturer?
- Ask where the garment will be sewn, in writing, before you discuss anything else. In this category that answer settles more than any other.
- Check Companies House. Confirm the company number, status and filing history on Companies House. A registered office is a legal address, often an accountant's or a serviced office, so it proves registration, not production. If a business trades under a name with no company behind it, ask which company will invoice you.
- Ask the machine question. Do you have flatlock and coverstitch machines, and are they on your premises? They are purpose-built for stretch seams and finishing, so their presence is a real signal.
- Ask how elastic is applied at each opening and at what tension, and how the size range will be graded. Someone who makes swimwear every day answers both quickly.
- Ask who owns the graded pattern. In swimwear the pattern carries much of the development cost and decides whether you can move production later without starting again.
- Ask which fabric and fibre the maker proposes, and for colour-fastness results to chlorinated and sea water.
- Sample, then test wet. Wash it, wear it, get it wet, look at it in daylight, then wash it again. Many swimwear faults appear only after water.
If your range includes wired styles, add one more question: which of them will be sewn on your premises, and if any go to a partner, where is that partner and what will the label say?

Frequently Asked Questions
What is the minimum order for UK-made swimwear?
It depends on the maker. Apparel Inspired, with a production unit on the North East coast, publishes minimums of 50 to 100 pieces per style depending on the product. The London Pattern Cutter in Greenwich says it works with no minimum order quantities and that all its production is in London. Our own group works from 100 pieces per style.
Can I get wired swimwear made in the UK?
It is hard to find. Apparel Inspired, for example, describes its UK swimwear service as non-wired and says wired designs are sourced and managed with a specialised overseas partner. Wired cups need channelling, moulding or structured panels and their own grading, so ask any maker directly whether wired styles are sewn on its own premises.
Does a London address mean the swimwear is made in London?
No. Ro & Ritzy, for example, gives a London office address and an Ahmedabad address, and describes itself as a factory that imports swimwear fabric into India for its clients. Origin follows where the garment was last substantially transformed, which for swimwear means where it was cut and sewn, so get the sewing location in writing.
How long does swimwear sampling take in the UK?
The London Pattern Cutter gives 2 to 6 weeks per sampling round and 4 to 12 weeks for production, depending on the project. Swimwear often needs more than one round, because wet fit, opacity and elastic tension can only be checked on a physical sample.
What import duty applies to swimwear made outside the UK?
Under the UK Global Tariff, women's and men's swimwear of synthetic fibres under headings 6112 41 90 and 6112 31 90 carries 12%, and women's synthetic swimwear with 5% or more rubber thread (6112 41 10) carries 8%. Swimwear from the EU, Turkey, Vietnam and, since 15 July 2026, India can enter at 0% if it meets the trade agreement's rules of origin and you hold proof of origin.
Why does swimwear lose its shape after a few wears?
Chlorine, salt water, sun cream and heat all attack elastane. Fabric built for swimwear uses more resistant elastane and is tested for it: colour fastness to pool water is tested under EN ISO 105-E03, which sets chlorine levels of 50 and 100 mg/l for swimwear. Ask your maker which fibre and which test results the fabric has.
