How to Enter the UK Construction Market? A Complete Guide for Polish Companies

The United Kingdom is one of the largest construction markets in Europe, and exporting building materials can be a real opportunity for Polish companies. Polish companies can make the most of this opportunity by exporting their products to the UK. However, since Brexit, the rules on imports, taxes and certification have changed.

In this article, we explain step by step how to register a limited company, get a VAT number and an EORI number, avoid unnecessary customs costs, and get your conformity marking (UKCA or CE) right. This will help you enter the British market in the most effective way.

1. Why it's worth entering the UK construction market

Here are a few reasons why expansion is worth considering:

2. Registering a limited company - the first step to trading legally

To sell building materials in the UK, it's worth setting up a limited company (LTD).

📌 Benefits of registering an LTD:

• Limited financial liability,
• Greater credibility in the eyes of British customers,
• The ability to open a UK bank account,

💡 Registration time depends on the method (online or paper) and whether the documents are correct – Companies House publishes up-to-date information on gov.uk.

3. VAT and EORI numbers - your tax obligations

Every company importing and selling goods in the UK should obtain two key tax numbers:

✅ VAT (Value Added Tax) number

• For UK-established businesses, mandatory once taxable turnover over the last 12 months exceeds £90,000; a business established outside the UK (such as a Polish company) must register regardless of turnover if it supplies goods or services in the UK (GOV.UK),
• It's worth registering earlier so you can reclaim VAT on costs.

✅ EORI (Economic Operators Registration and Identification) number

• Essential for import clearance in the UK (how to get an EORI number in the UK),
• Without it, you cannot complete customs clearance.

4. Will you have to pay customs duty?

Since Brexit, imports into the United Kingdom are subject to new customs regulations.

🔹 Will your products be subject to duty?
Every product has its own tariff code, which determines the level of duty.

🔹 How to reduce import costs?

• Check for preferential duty rates,
• Classify your product correctly.

📌 It's worth consulting a customs clearance specialist.

5. UKCA or CE marking - what applies after Brexit

Since 2021 Great Britain has had its own UKCA marking, but it has not displaced the CE mark.

✅ For construction products, CE marking remains available when placing products on the market in Great Britain; UKCA can also be used, which requires testing and certification by a UK approved body (gov.uk – Construction Products Regulation in Great Britain). A product with valid CE marking does not therefore automatically need re-assessment under UKCA.
✅ For most other product groups, CE is also still recognised alongside UKCA (gov.uk); see also UKCA certification explained.
✅ Many building materials require compliance testing, so it's worth checking the sector-specific regulations.

📌 Without the required conformity assessment and marking (UKCA or CE), you may not be able to sell on the UK market.

6. Do you need an office in the UK? A virtual address as a solution

You don't have to rent physical office space to register a company in the United Kingdom. You can use a virtual address that meets the legal requirements.

📌 Benefits of a virtual address:

• You can register your company lawfully,
• You get an address for official correspondence,
• It's cheaper than renting an office.

💡 The cost depends on the service provider you choose.
