What should I look for when hiring a CGI agency: a six-point checklist
The six checks below cover portfolio relevance, technical capability, turnaround times, pricing transparency, brand track record, and contract essentials. A studio that clears all six without you having to chase or negotiate for basic information is one worth working with.
1. Portfolio quality: does their work match your category?
A showreel is curated to impress, not to inform. What matters is whether the agency has produced work genuinely comparable to what you need, in terms of product category, visual style, and output format. A studio that excels at architectural visualisation may struggle badly with a reflective glass cosmetics bottle. Relevance beats raw quality every time.
The more telling test is consistency across a portfolio, not cherry-picking the best frame. Ask to see full project deliverables, not just hero shots. A reliable CGI production company shows consistent photorealism across angles, lighting conditions, and formats. One perfect still surrounded by mediocre work is a red flag, especially when you need multiple assets from a single production build.
2. Technical capability: what the studio can actually produce
An established 3D visualisation agency should be able to deliver across a broad capability stack: photorealistic product CGI, AI-directed video, FOOH (Fake Out of Home), 3D DOOH content, and 2D motion graphics. Many studios combine several of these disciplines, though specialism varies, so it's worth asking directly what a given studio handles in-house versus through partners. Each format serves a different campaign need. FOOH places a CGI product into real-world footage to simulate a physical OOH activation. 3D DOOH adapts that content for digital billboards and screens. AI video brings a different production approach but needs the same level of creative direction to land correctly.
Coordinating multiple suppliers across these formats can inflate cost, dilute creative direction, and create version-control complications. A studio that covers all formats from a single production build offers a meaningful operational advantage. That said, ask about the pipeline: leading studios use combinations of Maya, Cinema 4D, Blender, V-Ray, Redshift, and Unreal Engine. The right question is not which software they use, but whether their pipeline suits your deliverable, whether that's photorealistic stills, broadcast-quality animation, or real-time assets. Ask about their render engine, compositing process, and whether they can supply layered render passes or ProRes masters for post-production.
3. Turnaround times and how the studio actually operates
Here are practical benchmarks worth knowing before you brief anyone. A single polished product still takes one to two weeks. A set of five to ten product shots runs two to four weeks. A thirty-to-sixty-second animation typically takes four to seven weeks. These are planning benchmarks, not guarantees. Timelines expand when source files are poor, briefs shift mid-project, or feedback cycles are slow. Any studio that promises significantly faster without qualifying it is either underselling the complexity or setting you up for disappointment.
The speed and clarity of a studio's quoting process tells you a lot about how they'll behave throughout the project. A studio that takes two weeks to send a quote, or provides a vague budget range with no line-item detail, is showing you exactly how they operate. Prompt, detailed quotes are a strong positive signal; if an agency can't provide a clear cost and timeline within a reasonable timeframe, ask why before you commit. When you're comparing options, studios that respond quickly and with specificity are generally the ones that run tighter projects.
4. Pricing transparency: what your quote should actually cover
A thorough quote from a reputable CGI agency covers 3D modelling (from CAD files or from scratch), materials and textures, lighting, number of camera angles, revision rounds, final file formats, and delivery specifications. The first image or scene setup costs more because it includes the foundational production build. Subsequent angles or variants are proportionally cheaper. For a rough UK orientation, stills for a quality product typically start from around £500, rising to £1,500 or more for premium hero imagery, while a polished thirty-to-sixty-second animation generally starts around £5,000 to £10,000 depending on complexity. Figures vary based on whether 3D modelling is required from scratch and the level of finishing expected.
The items most commonly left off an initial quote are worth clarifying before you sign:
- Source file ownership and editable project files
- Additional aspect ratios and social cutdowns (square, portrait, Stories formats)
- Rush delivery fees and out-of-hours charges
- VAT, which UK agencies commonly quote excluding
- Music licensing, voiceover, and sound design
- Revisions beyond the agreed number of rounds
That last point needs particular attention. "Revisions" must be defined in writing before production starts. A change to a camera angle is different from a change to the product design mid-production. What counts as a revision versus a change to the brief affects cost significantly, and a well-run studio will make that distinction clear upfront rather than presenting a surprise invoice at delivery.
5. Client references and proven brand track record
A shortlist of client logos on a website proves nothing on its own. Ask for at least two references you can contact directly, ideally from brands in a similar sector or with comparable project scope. The questions worth asking: did they deliver on time, how did they handle revisions, and would you hire them again? Those answers are almost always more revealing than any portfolio.
The signals that separate studios with a genuine track record from those padding their credentials are straightforward. Repeat clients, publicly credited campaigns, and named brands rather than anonymised references are all positive indicators. A CGI production company that has delivered for globally recognised brands across multiple campaigns has demonstrated its process works under real commercial pressure. When you speak to a reference, ask one final question: knowing what you know now, would you hire this agency again for a similarly important project, and what would you put in the contract differently? That answer is worth more than any testimonial on a website.
6. Contract essentials: IP, revisions, and confidentiality
In the UK, copyright sits with the creator unless explicitly assigned in writing. That means if your contract doesn't include a clear assignment clause, the studio may retain ownership of everything they've produced for you, even after you've paid in full. A reliable CGI services provider should include a written services agreement that assigns all IP in the bespoke deliverables to you, worldwide, perpetually, across all media. If the studio uses background materials such as pre-built models, plugin tools, or internal templates, those should be covered by a perpetual licence. Any vague wording around "usage rights" or "licences for the project term" should be flagged and resolved before you sign anything.
Beyond IP, three additional contract essentials matter. Nail these down before production begins:
- Revision rounds: Define how many are included and what constitutes a revision versus a scope change. Require that no chargeable extra work begins without your written approval.
- Confidentiality: Particularly important when the work involves an unreleased product. Require NDA protection for briefs, files, and renders, and confirm that the studio cannot upload your confidential material to external AI tools or cloud services without your consent.
- Third-party assets: Require written disclosure of any stock models, music, or fonts used, and confirm the licence covers your intended commercial use, territory, and duration.
A studio that pushes back on any of these clauses is one worth reconsidering before you commit budget to them.
Hire with your eyes open
Knowing what to look for when hiring a CGI agency comes down to six fundamentals: portfolio relevance, technical range, realistic timelines, transparent pricing, a verifiable track record, and clean contracts. These are not high bars, they are the baseline for a professional production relationship.
The best way to test a CGI studio before you commit is to brief them on something real and see how they respond. Do they ask the right questions? Does their quote arrive promptly and cover the detail you'd expect? Is their process clear? The answers tell you more than any showreel. MAD CGI offers quotes within one business day of receiving a detailed brief, a useful benchmark when evaluating how other studios handle the same request. Use this checklist not just to avoid poor hires, but to recognise a genuinely capable studio when you find one.
