The most common budgeting mistake in UK clothing production is quoting the CMT (Cut, Make, Trim) rate as the unit cost. CMT is labour only. It excludes fabric, trims, pattern cutting, grading, sampling, and packaging — components that routinely add 60–120% on top of the CMT figure.
A factory that quotes you £8 CMT for a jersey top is not telling you the garment costs £8 to produce. It is telling you that cutting and sewing costs £8. The total unit cost will be somewhere between £16 and £28 depending on your fabric choice, trim specification, and volume.
This guide breaks down every cost component — with 2026 price ranges — so you can build an accurate budget before your first factory conversation.

What Drives UK Clothing Manufacturing Costs
The UK National Living Wage rose to £12.71 per hour from 1 April 2026, up 4.1% from the previous rate of £12.21. (Source: Low Pay Commission — National Minimum Wage in 2026, March 2026.) In London, the Real Living Wage sits at £14.80 per hour from May 2026. (Source: Living Wage Foundation, October 2025.)
Labour is the single largest variable cost in UK domestic production — and it is rising faster than offshore equivalents. This is not a reason to avoid UK manufacturing. It is a reason to build your budget with current labour rates, not with figures from two years ago.
Four factors determine your unit cost more than any other:
Garment complexity. A plain jersey t-shirt requires 8–12 minutes of Standard Minute Value (SMV) to cut and sew. A structured jacket with lining, interfacing, and multiple panels requires 60–90 minutes. At £12.71 per hour, the labour difference between those two garments is approximately £9–£15 per unit before any other cost is applied.
Volume per style per colourway. UK factories price on volume tiers. The unit cost at 50 pieces per style is typically 30–50% higher than at 200 pieces, because setup time (lay planning, marker making, machine calibration) is amortised across fewer units at low quantities.
Production model. CMT requires you to supply cut fabric and patterns. Full-service requires the factory to source fabric and develop patterns. Full-service costs more per unit but eliminates your logistical management burden. For brands producing under 300 units per style, the hidden costs of CMT logistics — fabric shipping, trim sourcing, pattern development commissioned separately — often make full-service the more cost-effective total model.
Fabric specification. Fabric is typically the largest single cost component, often 40–60% of the total unit cost for basics. The grade, GSM, composition, and sourcing lead time all affect both price and production scheduling.
2026 UK CMT Cost Benchmarks by Garment Type
These are CMT-only rates — labour to cut, make, and trim. Fabric, pattern cutting, grading, and packaging are excluded.
| Garment type | CMT cost range | Volume assumption | Key cost driver |
|---|---|---|---|
| Basic jersey t-shirt | £5–£10 | 100–300 units | Simple construction, fast SMV |
| Printed hoodie / sweatshirt | £12–£20 | 100–200 units | Panel count, pockets, finishing |
| Tailored trouser / chino | £15–£28 | 50–150 units | Waistband, lining, fly construction |
| Casual dress (jersey) | £10–£18 | 100–200 units | Length and seam complexity |
| Structured dress (woven) | £20–£38 | 50–150 units | Zip, lining, interfacing |
| Activewear set (top + legging) | £18–£30 | 100–200 units | Stretch fabric handling, flatlock |
| Outerwear / structured jacket | £35–£65 | 30–100 units | Lining, interfacing, panel count |
| Knitwear (mid-gauge sweater) | £22–£45 | 30–100 units | Linking seams, garment-dyed finish |
| Workwear shirt | £10–£18 | 100–300 units | Collar, cuffs, button placket |
| Bespoke / complex tailoring | £55–£120+ | Under 30 units | Handwork, multiple fittings |

The ranges reflect volume tiers within each category. At minimum quantities, expect the upper end of each range. At 200+ units per style, expect to negotiate toward the lower end.
The Full Unit Cost — What Brands Actually Pay
CMT is one line item. Here is how the full unit cost builds for a mid-complexity garment (printed sweatshirt, 150 units per style):
| Cost component | Price range | Notes |
|---|---|---|
| CMT (cut, make, trim) | £14–£18 | Labour to produce the finished garment |
| Fabric | £8–£14 | Jersey fleece, mid-weight, brand-sourced |
| Trims (labels, thread, zips, drawcords) | £1.50–£3.00 | Per unit share of trim cost |
| Packaging (poly bag, hang tag, size sticker) | £0.50–£1.50 | Per unit |
| Fabric shipping to factory | £0.30–£0.80 | Per unit share of freight cost |
| Pattern cutting (amortised per unit) | £0.80–£2.00 | Based on £200–£400 pattern fee, 150 units |
| Grading (amortised per unit) | £0.40–£1.00 | Based on £60–£150 grading fee, 150 units |
| Total unit cost (estimate) | £25.50–£40.30 | Before sampling costs or QC visits |
The retail price of a £55–£85 sweatshirt at this unit cost leaves a margin of 35–55% at wholesale (assuming 2.2–2.5x wholesale markup from unit cost). That is a workable position for most brands. The mistake is building the business model on the CMT rate alone and discovering the true unit cost only after the first production invoice.

Pre-Production Costs: The Budget Line Every Brand Forgets
Pre-production costs are paid before a single bulk unit is produced. They are non-negotiable. Most brands budget for them inadequately on their first production run.
Mistake 1 — Treating sampling fees as sunk costs to minimise. Why it happens: Brands view sampling as an administrative hurdle rather than a technical process. Exact fix: Budget £150–£400 per sample round for a UK CMT factory (£25–£50 per hour, 3–8 hours per sample garment). Expect a minimum of two rounds — first fit sample and pre-production sample. Budget £600–£1,200 for sampling before a single bulk unit is approved. For complex or tailored garments, three rounds is normal.
Mistake 2 — Ignoring pattern cutting costs. Why it happens: Brands assume the factory includes pattern cutting in the CMT rate. Exact fix: Most UK CMT factories require you to supply a production-ready graded pattern. Pattern cutting by a professional pattern cutter costs £150–£450 per style depending on complexity. Grading across a standard size run (XS–XL, five sizes) adds £60–£200. These are per-style costs paid once — but they are real costs that must appear in your pre-production budget.
Mistake 3 — Not accounting for fabric minimum lengths. Why it happens: Brands calculate fabric cost based on exactly the metres required. Exact fix: Fabric mills sell by the roll or by minimum cut length — typically 30–50 metres minimum. If your 150-unit style requires 1.5m per unit (225m total), you are in a manageable position. If your 50-unit style requires 1.5m per unit (75m total), you may still need to purchase a 100m minimum cut — paying for 25m of fabric you cannot use. Factor wastage (10–15%) and minimum cut lengths into every fabric cost calculation.
Mistake 4 — Forgetting tech pack development. Why it happens: Brands submit a reference garment and expect the factory to work from it. Exact fix: A professional tech pack costs £200–£600 per style if commissioned from a freelance garment technologist. It is not optional for CMT production. Without a precise tech pack specifying stitches per inch, seam types, tolerance, and construction sequence, the factory cannot be held accountable to any quality standard. Budget this cost explicitly — do not try to absorb it into the CMT rate.
Mistake 5 — Underestimating QC costs. Why it happens: Brands assume the factory handles quality control as part of the CMT price. Exact fix: UK factories will reject defective units within their own production process. End-of-line quality control — checking the finished bulk order against your specification — is your responsibility. A QC inspection visit costs a day of your time and travel. A third-party inspection firm charges £250–£500 per day. Build one QC cost into every production run budget.
Pre-Production Cost Summary
| Pre-production cost | Price range | Per style or per run? |
|---|---|---|
| Pattern cutting | £150–£450 | Per style |
| Grading (5-size run) | £60–£200 | Per style |
| Tech pack development | £200–£600 | Per style |
| First fit sample | £150–£350 | Per style |
| Pre-production sample | £120–£280 | Per style |
| Fabric swatch approval | £20–£60 | Per colourway |
| QC inspection (own visit) | £50–£200 travel | Per production run |
| QC inspection (third party) | £250–£500 | Per production run |
| Minimum pre-production budget (one style) | £700–£1,900 | Before any bulk production |
For a brand launching three styles in two colourways each, pre-production costs before any bulk units are produced typically fall between £3,500 and £9,000. This figure shocks most founders — because most online guides do not include it.
How Volume Affects Your Unit Cost
Volume is the most powerful lever in UK clothing manufacturing pricing. The economics at 50 units per style are fundamentally different from those at 300 units per style.
At 50 units, setup costs (marker making, machine calibration, lab dip approval) are amortised over a small run. Pattern-to-unit overhead is high. Factories also apply a low-volume premium — typically 25–40% above their standard rate — because small runs disrupt production scheduling and reduce machine efficiency.
At 200 units per style, setup costs spread more thinly, the factory achieves a viable production run length, and per-unit overhead falls. At 300+ units, some factories offer volume discounts of 10–20% below their base rate.
The practical implication: if you are producing 50 units per style and wondering why your unit cost feels high, the answer is almost always volume, not factory pricing. The fix is either to consolidate styles (fewer styles, higher units per style) or to accept the premium as the cost of small-batch flexibility.
Frequently Asked Questions
How much does it cost to manufacture a t-shirt in the UK in 2026?
A basic jersey t-shirt in the UK costs approximately £16–£28 per unit at 100–200 units per style, covering CMT (£5–£10), fabric (£4–£8), trims and packaging (£2–£4), and pattern/grading amortisation (£1.50–£3.50). At 50 units per style, expect the upper end of that range or above. At 300+ units, experienced brands have brought total unit costs on basics below £14 by consolidating fabric purchasing and negotiating volume terms.
What is the difference between CMT and full-service manufacturing costs?
CMT is labour only — you supply all materials, patterns, and trims. Full-service manufacturers source fabric, develop patterns, and manage trims on your behalf. Full-service unit costs run 40–70% higher than CMT labour rates, but the full-service model eliminates your logistics burden and the hidden costs of separately commissioning pattern cutting, grading, and fabric sourcing. For brands producing under 200 units per style, full-service often delivers a lower true total cost than CMT once all pre-production costs are counted.
How much should I budget for my first UK clothing production run?
For a realistic first production run of three styles at 100–150 units each, budget: pre-production costs £3,000–£7,000 (pattern cutting, grading, tech packs, two sampling rounds per style), plus bulk production costs £8,000–£18,000 (CMT + fabric + trims + packaging at 300–450 total units). Total first run budget: £11,000–£25,000. Brands that budget under £8,000 for a three-style launch are almost always underestimating pre-production or underestimating fabric costs.
Why are UK manufacturing costs higher than offshore?
UK manufacturing costs are higher primarily because UK labour rates are significantly higher than those in Bangladesh, Turkey, or Portugal. The National Living Wage of £12.71 per hour from April 2026 sets the minimum labour floor — well above comparable rates in major offshore production countries. UK factories also carry higher overhead costs: factory rent, energy, compliance, and employer National Insurance. These are structural costs that cannot be negotiated away. The commercial case for UK manufacturing rests on lead time, quality control accessibility, and the Made in Britain positioning opportunity — not on unit cost competition with offshore.
Do UK clothing manufacturers charge VAT on manufacturing costs?
Yes. UK manufacturing services are subject to 20% VAT. If your brand is VAT-registered, you reclaim the input VAT on your quarterly return. If you are not yet VAT-registered (turnover under £90,000), you pay VAT without reclaim — which adds 20% to your effective manufacturing cost. Most fashion brands reach the VAT registration threshold within their first two or three seasons once bulk production begins. Factor this into your early-stage cost modelling.
Building a Realistic Production Budget
The brands that run into cash flow problems in their first production season are almost always the ones who budgeted on CMT rates alone and treated fabric, pattern cutting, sampling, and pre-production as afterthoughts.
The full picture: pre-production costs are fixed per style regardless of volume. Bulk production costs scale with volume. At low volumes, pre-production represents 30–50% of your total spend. At higher volumes, it compresses to 10–20%. The implication for launch strategy: launching with fewer styles at higher unit quantities almost always produces better unit economics than launching with many styles at low quantities.
