UK market entry checklist for SMEs: 27 things to do before your first sale

How to use this checklist

Most UK market entry checklists you'll find online are unordered dumps of every possible task — useful as a memory aid, useless as an execution plan. This one is sequenced. Do the items in order; the later items depend on the earlier ones.

Each item is written as a decision or a deliverable, not a topic. If you can't tell whether an item is done, it isn't done. Cost bands assume mid-2026 pricing and unregulated products; regulated categories (medical devices, food supplements, cosmetics, chemicals) add cost and time to the compliance block.

• Blocks 1–3 (weeks 1–4): legal, tax and banking foundations.
• Blocks 4–5 (weeks 3–10): product compliance and logistics.
• Block 6 (weeks 6–12): commercial launch — channel, pricing, first shipment.

Block 1 — legal and corporate setup (weeks 1–2)

You cannot register for VAT, open a UK bank account, or sign a UK distributor contract without deciding your legal structure first. Do this block before anything else.

• 1. Decide entry structure: UK Ltd, UK branch of your foreign parent, or third-party importer of record. (Free — decision only.)
• 2. If UK Ltd: reserve a company name and confirm it isn't restricted. (Free.)
• 3. Incorporate the UK Ltd via Companies House. (£12–£40, 24 hours to 5 working days.)
• 4. Appoint at least one director and one PSC (person with significant control). (Included above.)
• 5. Register a UK service address — home addresses are public on Companies House, so most SMEs use a registered-office service. (£40–£150/year.)

Block 2 — HMRC registrations (weeks 2–3)

HMRC needs to know you exist as a UK taxpayer before you can import, hire, or invoice. These registrations are free but each has its own processing time — start them in parallel.

• 6. Register the company for UK corporation tax. (Free — automatic 3 months after incorporation, but confirm.)
• 7. Apply for an EORI number (starts with GB). Required for any customs declaration. (Free, ~5 working days.)
• 8. Decide UK VAT timing: register voluntarily now, or wait for the £90,000 rolling-12-month threshold. (See our UK VAT guide.)
• 9. If registering for VAT: complete VAT1 online and pick a scheme (standard, flat rate, cash accounting). (Free, 10–30 working days for the VRN.)
• 10. If you'll hire anyone in the UK: register as an employer for PAYE. (Free, up to 15 working days.)

Block 3 — UK banking and payments (weeks 2–4)

UK banking is the single most common bottleneck for foreign-owned SMEs. High-street banks (HSBC, Barclays, NatWest) still routinely reject accounts for companies with no UK-resident director. Plan for two parallel applications from day one.

• 11. Open a Wise Business or Revolut Business account for immediate GBP receiving. (Free–£25/month, 1–7 days.)
• 12. Apply to a UK challenger bank (Tide, Starling, Monzo Business) for a full UK sort code and cheque handling. (Free–£10/month, 1–4 weeks.)
• 13. Optional: apply to a high-street bank if you'll need a merchant account, credit facility, or FX hedging over £250k/year. (Free, 4–12 weeks.)
• 14. Set up a UK payment processor: Stripe UK, GoCardless (Direct Debit), or a Worldpay account if you'll take card-present payments. (2%+/transaction.)

Block 4 — product compliance and safety (weeks 3–10)

This is where most SMEs underestimate time and cost. The CE mark alone is no longer sufficient for many product categories placed on the GB market — UKCA marking, sectoral schemes, or specific product registrations apply instead. Start this block in parallel with banking; do not wait for shipments to trigger it.

• 15. Identify your HS/commodity code (10-digit). This drives tariff, VAT, and regulator selection. (Free via GOV.UK Trade Tariff.)
• 16. Identify your UK sector regulator: FSA/DEFRA (food), MHRA (medical devices, cosmetics, supplements), OPSS (general product safety, construction), DVSA/VCA (automotive), HSE (chemicals, machinery). (Free — desk research.)
• 17. Complete the conformity assessment the regulator requires: UKCA marking, MHRA registration, cosmetic product notification, etc. (£500–£15,000+ depending on category.)
• 18. If applicable, appoint a UK Responsible Person or UK Authorised Representative. Required for cosmetics, most medical devices, and some construction products. (£1,000–£4,000/year.)
• 19. Prepare a UK-address technical file. Regulator inspections and Trading Standards can request it at any time. (Internal.)
• 20. Register your product on any mandatory database (SCIP for hazardous chemicals, MHRA device register, cosmetic CPNP-equivalent). (Free–£800.)

Block 5 — logistics, customs and IoR (weeks 6–10)

Nothing here is optional. Every shipment needs an importer of record, a customs declaration, and a landed-cost model that reflects duty, VAT, freight, and last-mile charges.

• 21. Confirm importer of record: your UK Ltd, or a third-party IoR service. (£150–£400/shipment plus retainer if outsourced.)
• 22. Select a customs broker — most 3PLs bundle this. Confirm they file both entry summary declarations and full customs entries. (£25–£75/entry.)
• 23. Model landed cost per SKU: FOB + freight + duty + VAT + 3PL in + last-mile + returns reserve. (Free — spreadsheet.)
• 24. Contract a UK 3PL for storage and pick-and-pack. (£3–£8/order + storage.)

Block 6 — commercial launch (weeks 6–12)

You should be able to invoice a UK customer by the end of week 12. If any item in Blocks 1–5 slips into Block 6, revisit the plan — do not launch commercially against unresolved compliance or banking gaps.

• 25. Sign your first commercial channel: a distributor agreement, an Amazon UK Seller Central account, or a Shopify UK-tax-configured storefront. (Variable.)
• 26. Ship the first commercial pallet (not a sample) and file the first customs entry end-to-end.
• 27. Take the first UK invoice, book it in GBP through your UK books, and reconcile against your first VAT return.

Automate this checklist with the Entrida assessment

Entrida's Market Entry Assessment (£95) runs this checklist against your specific business: it scores your readiness across five pillars, names your regulator and conformity route from your HS code, shortlists verified UK partners for each block (accountant, solicitor, IoR, 3PL), and outputs the sequenced 12-week plan as concrete tasks with owners and dates.

If you want the checklist without paying, start with the free 2-minute snapshot — it's the trimmed version, enough to tell you whether any item in Blocks 1–5 has a showstopper before you invest.
