Key Takeaways

Essential Points for Employers

• CAD drawing and architectural technicians fall under SOC Code 3120 - Draughtspersons and related architectural technicians.
• The role is eligible for a Skilled Worker visa, so UK employers with a sponsor licence can recruit internationally.
• Candidates must meet the minimum salary threshold, English language requirements and skills criteria set by the Home Office.
• Sponsors must assign a Certificate of Sponsorship (CoS) and maintain compliance records throughout the worker's employment.

What Is SOC Code 3120?

SOC Code 3120 covers draughtspersons and related architectural technicians. This group prepares technical drawings, plans and specifications used in construction, engineering and design projects. The Office for National Statistics assigns SOC codes to occupations for statistical and immigration classification purposes, and the Home Office uses them to determine which roles qualify for the Skilled Worker route.

Job Titles Typically Covered

• CAD technician
• Architectural technician
• Draughtsperson
• Architectural draughtsperson
• Building technician
• CAD drawing technician
• Structural draughtsperson
• Design technician (construction or engineering)

Employers should ensure the job title used in the Certificate of Sponsorship is consistent with the duties performed and with the SOC code assigned. Mismatches between the stated role and actual responsibilities are a common compliance issue identified during Home Office audits.

Role and Responsibilities

CAD drawing and architectural technicians translate design concepts and engineering specifications into accurate, detailed technical drawings. Their work sits at the intersection of design, construction and compliance, making them essential to delivery teams in architecture practices, engineering consultancies, construction firms and manufacturing companies.

Skilled Worker Visa Eligibility for SOC Code 3120

SOC Code 3120 appears on the list of eligible occupations for the Skilled Worker visa. This means UK employers with a valid sponsor licence can recruit CAD drawing and architectural technicians from outside the UK, provided the candidate and the role both meet the required criteria.

Points-Based Requirements

• A valid job offer from a licensed sponsor - 20 points
• The role must meet the required skill level (RQF Level 3 or above) - 20 points
• English language proficiency at B1 level or above - 10 points
• Minimum salary threshold - the higher of the general threshold, the going rate for SOC 3120, or the new entrant rate where applicable

Salary Thresholds

From April 2024, the general Skilled Worker salary threshold increased to £41,700 per year. The going rate for SOC Code 3120 should be checked against the current Home Office salary appendix, as going rates are updated periodically. New entrant rates, which apply to recent graduates and those switching from certain visa categories, may allow a lower salary for a limited period. Employers should verify the current figures on the gov.uk going rates page before issuing a Certificate of Sponsorship.

Sponsor Licence Obligations

To hire an overseas CAD or architectural technician under the Skilled Worker route, the employer must hold a valid sponsor licence issued by the Home Office. Sponsors take on a set of ongoing legal duties when they bring in overseas workers.

Key Sponsor Duties

• Assign a Certificate of Sponsorship with accurate role, salary and start date information
• Carry out right to work checks before employment begins and keep copies of relevant documents
• Report changes to the worker's role, salary or circumstances through the Sponsor Management System
• Notify the Home Office if the worker does not attend their first day, is absent without explanation, or leaves employment
• Maintain up-to-date contact details and HR records for every sponsored worker
• Cooperate with any Home Office compliance visit or audit

Failure to meet these duties can result in sponsor licence suspension or revocation, which prevents the employer from sponsoring further workers and may affect current sponsored staff. Annaizu helps employers manage these obligations through a structured compliance platform designed around Home Office requirements.

Applying for a Sponsor Licence

Employers who do not yet hold a sponsor licence will need to apply before they can issue a Certificate of Sponsorship. The application is submitted through the Home Office online system and requires the business to demonstrate that it is genuine, solvent and capable of fulfilling sponsor duties.

Steps to Apply

1. Check your business is eligible and that the role meets the skill and salary requirements for SOC Code 3120.
2. Appoint an Authorising Officer, Key Contact and at least one Level 1 User in the Sponsor Management System.
3. Gather supporting documents - Companies House registration, employer's liability insurance, financial evidence and HR policy documentation.
4. Submit the application online and pay the relevant fee (currently £536 for small sponsors and £1,682 for medium or large sponsors).
5. Await the Home Office decision, which typically takes up to eight weeks, or use the priority service if available.

Right to Work Checks for CAD Technicians

All employers in the UK must conduct right to work checks before a new employee starts work, regardless of their nationality. For overseas nationals sponsored under the Skilled Worker route, the check involves verifying the visa vignette or eVisa status and confirming the worker is permitted to undertake the specific role.

Acceptable Check Methods

• Online Home Office right to work checking service using the worker's share code
• Manual document check for British and Irish citizens using passport or birth certificate plus National Insurance evidence
• Identity Document Validation Technology (IDVT) for British and Irish citizens via an approved provider

Employers must retain a copy of the check outcome and the date it was conducted. Checks must be repeated when a worker's permission to work is time-limited and is due to expire.

Recruiting CAD Technicians from Overseas

The UK faces a skills shortage in technical design roles, particularly in firms working on large infrastructure, residential or commercial projects. International recruitment can fill gaps where domestic candidates are not available, but the process involves lead times that employers should plan around.

Typical Recruitment Timeline

1. Confirm the role meets SOC Code 3120 criteria and the salary meets the threshold.
2. Identify and shortlist overseas candidates through recruitment channels, job boards or agency partners.
3. Issue a Certificate of Sponsorship once a suitable candidate is selected.
4. Candidate applies for a Skilled Worker visa
