SOC Code 3120 covers CAD, drawing and architectural technicians — technical staff who produce detailed drawings, plans and models to support architects, engineers and construction teams, without holding the professional qualifications of a registered architect or engineer. It's a technician-level occupation, not a substitute code for sponsoring an architect.
Technician, not architect
Architects sponsored as professionals need to be assessed against their own, higher-skilled occupation code. Using 3120 for someone actually practising as an architect — rather than producing technical drawings under supervision — misassigns the role and undermines the genuineness of the certificate. Getting this distinction right at the point of assignment avoids a much harder conversation at a compliance visit later.
One code, several related disciplines
3120 is broader than the 'architectural technician' label suggests — it also covers civil and structural drawing technicians, building surveying technicians and similar technical drafting roles across construction and engineering, not only those working directly for an architectural practice. That breadth is useful, because a construction or engineering firm doesn't need to force a structural CAD technician into an unrelated code — but it also means the job description still has to be specific about which discipline the worker actually supports, rather than a generic 'technician' title with no detail on the drawings or systems they produce.
The rise of Building Information Modelling as standard practice on larger projects has also blurred old boundaries: a 'BIM technician' or 'BIM coordinator' producing and maintaining 3D models rather than 2D drawings can sit within 3120 too, provided the role is genuinely technical rather than a design-authority position. The label on the job title matters less than whether the worker is producing and maintaining technical models and drawings under the direction of qualified professionals, rather than making independent design decisions.
Qualifications are the evidence that carries the most weight
Technician roles are usually supported by a relevant qualification — an HNC, HND, or equivalent in architectural technology, construction or CAD — plus, often, membership of a professional body. Copies of these qualifications, along with the job description setting out day-to-day drawing and technical support duties, are exactly the kind of documents Appendix D expects a sponsor to hold and produce on request; see the Home Office's record-keeping duties guidance. For overseas qualifications, a UK ENIC equivalency statement is a straightforward way to document that equivalence if it's ever questioned.
Software competence is worth documenting alongside formal qualifications. Proficiency in the specific CAD or BIM package the role actually uses — AutoCAD, Revit or an equivalent — and evidence of professional development, such as working toward CIAT (Chartered Institute of Architectural Technologists) membership, help build a fuller picture of a genuine technical role than the qualification certificate on its own.
Employment status: a genuine employee, not a freelance arrangement
CAD and drawing work is commonly done on a freelance or contract-for-service basis in the construction sector, and that's precisely the arrangement Skilled Worker sponsorship can't be used for. A sponsor must be the worker's actual employer, with the control, mutual obligation and integration into the business that a real employment relationship implies — not a client engaging a self-employed technician project by project. Where a technician has previously worked freelance, it's worth making sure the new arrangement is unambiguously employed status, with the paperwork — contract of employment, PAYE, day-to-day supervision — to match.
Day rates and the salary threshold
Construction and engineering technicians are sometimes engaged, or previously worked, on a day-rate basis rather than an annual salary, and that pay structure needs converting into a genuine, guaranteed annual salary equivalent to be assessed against the threshold and going rate — a day rate that looks generous on paper doesn't automatically clear the bar once it's annualised, especially if the role involves fewer guaranteed working days than a standard full-time contract. Sponsors moving a previously freelance or day-rate technician onto a sponsored contract should work out the guaranteed annual figure carefully, rather than assuming the headline day rate translates cleanly.
Confirm the code before you assign the certificate
3120 is one of many similar-sounding technical codes on the eligible occupations list, and mismatches between the code, the going rate and the actual job description are a common source of avoidable Certificate of Sponsorship errors. Cross-check the role against the published occupations and SOC codes list and the relevant going rate before assigning, and set a reminder to revisit it if the worker's duties or seniority change — a reminders system is a simple way to make sure that review actually happens rather than being forgotten. Keeping qualification and CoS records together in one place, via secure document management, also saves time when renewing the licence.
FAQs
Does the technician need UK-recognised qualifications?
Overseas qualifications can be accepted where they're broadly equivalent, but the sponsor should be able to explain and evidence that equivalence if asked.
What happens if a technician is promoted into architect-level duties?
A genuine change in role and skill level generally means the SOC code and Certificate of Sponsorship need updating to match — the sponsorship shouldn't quietly drift out of step with the job actually being done.
Can a newly qualified technician be paid under the new entrant salary rate?
Often yes, if they genuinely meet the new entrant criteria — such as being early in their career or still working toward full qualification — but the sponsor should check the specific criteria apply rather than assume every junior hire qualifies.
