EN 1090 Consultancy | Structural Steel & Aluminium Compliance
AJC provides specialist EN 1090 consultancy to manufacturers and fabricators of structural steel and aluminium components.
We support organisations in achieving and maintaining compliance with EN 1090, the Construction Products Regulations (CPR), and CE / UKCA marking requirements, ensuring legal market access and audit-ready factory production control systems.
EN 1090 is a mandatory European standard governing the manufacture of structural steel and aluminium components used in construction.
How We Support EN 1090 Compliance
Our EN 1090 consultancy follows a structured, regulator-aligned approach designed to achieve compliance efficiently while minimising disruption to fabrication and production activities.

Initial Consultation
We assess your fabrication activities, product scope, execution class requirements, and market obligations (UK, EU, or both) to determine the correct EN 1090 compliance route.

EN 1090 Gap Analysis
We review your existing factory production control (FPC), welding arrangements, quality controls, and documentation to identify gaps against EN 1090 and CPR requirements.

Tailored EN 1090 Implementation
We implement compliant FPC systems, procedures, records, and controls aligned with your actual manufacturing processes.

CE / UKCA Marking & Ongoing Support
We support notified body engagement, CE or UKCA marking preparation, surveillance audits, and ongoing compliance maintenance.
What Is EN 1090?
In simple terms, EN 1090 controls how structural steel and aluminium components are manufactured, assessed, and legally placed on the market.
EN 1090 is a European standard that sets the requirements for the design, manufacture, and conformity assessment of structural steel and aluminium components used in construction.
It ensures that fabricated metalwork:
Meets defined technical standards
Is manufactured under controlled conditions
Is safe, traceable, and legally compliant
Under EN 1090, manufacturers must demonstrate conformity and apply the appropriate CE or UKCA marking, certifying compliance with construction product regulations.
Since 1 July 2014, EN 1090 compliance has been mandatory for structural metal products placed on the European market. The standard remains applicable in the UK, with updated conformity marking requirements following Brexit.
Failure to comply can result in legal penalties and restrictions on market access.
What Is EN 1090-1:2009+A1:2011?
If you manufacture structural steel or aluminium components, you must comply with BS EN 1090-1.
BS EN 1090-1 specifies the requirements for conformity assessment and factory production control (FPC) for steel and aluminium structures. It defines:
Execution class requirements
Assessment and verification of constancy of performance (AVCP)
Technical documentation and declarations
Manufacturer responsibilities
Compliance with BS EN 1090-1 is a legal requirement for CE or UKCA marking of structural components.
Structure of EN 1090 Standards
EN 1090 consists of three interrelated parts:
EN 1090-1
Assessment and verification of constancy of performance (CE / UKCA marking)
EN 1090-2
Technical requirements for the manufacture and assembly of steel structures
EN 1090-3
Technical requirements for the manufacture and assembly of aluminium structures
If you are CE or UKCA marking structural components, compliance with EN 1090-1 and the relevant Parts 2 and/or 3 is required, depending on the materials used.
Who Enforces EN 1090?
Because EN 1090 is a legal requirement, enforcement action applies where compliance is not achieved.
In the UK, EN 1090 compliance is enforced under the Construction Products Regulations (CPR) 2013 and overseen by Trading Standards.
Non-compliance is a criminal offence and may result in:
- Up to 3 months’ imprisonment, and/or
- A fine of up to £5,000 on summary conviction
This enforcement applies to manufacturers, importers, and distributors placing non-compliant structural products on the market.
Who Is Affected by EN 1090?
Manufacturer Responsibilities
If you manufacture structural steel or aluminium products sold in the UK or European Economic Area (EEA), you are legally required to apply the appropriate conformity marking.
Each product supplied must be accompanied by:
Correct declarations of performance
Supporting technical documentation
Evidence of compliant factory production control
EN 1090 places legal obligations on manufacturers, distributors, and importers of construction products.
EN 1090 & the UK Market – Post-Brexit Changes
Following the UK’s exit from the EU:
EU legislation still applies to organisations manufacturing or exporting steel and aluminium structures into the EU
Businesses selling only within the UK must apply UKCA marking instead of CE marking
CE marking remains valid for products exported to the EU, provided all EU requirements are met
Important Note
If products intended for the EU were assessed by a UK-based notified body, they must:
Be reassessed by an EU-recognised notified body, or
Have documentation formally transferred
If this is not possible, products must be re-marked with the details of the EU-recognised body.
CE Marking vs UKCA Marking – What Should You Use?
CE Marking
Required for products placed on the EU / EEA market and assessed by an EU-recognised notified body.
UKCA / UKNI Marking
Required for products placed on the UK market and assessed by a UK-recognised conformity assessment body.
Our EN 1090 consultancy ensures:
No disruption to sales or contracts due to non-compliance
Correct marking is applied based on your markets
Documentation meets regulatory expectations
Benefits of EN 1090 Compliance
Legal access to UK and EU construction markets
Eligibility to apply CE or UKCA marking
Improved production control and traceability
Increased confidence from contractors and specifiers
Reduced regulatory and contractual risk
