Typical claim values for digital and creative agencies
When agency work does qualify, claims typically range from £12,000 to £50,000 per year — lower than engineering or software product companies because the proportion of work involving genuine technological uncertainty is usually smaller relative to total fee income. Agencies that develop their own proprietary tools, platforms, or technology (rather than exclusively working on client deliverables) typically have the strongest qualifying positions.
Three qualifying activity examples
The key distinction for agencies is between client delivery work (which rarely qualifies) and work that involves resolving genuine technological uncertainty — regardless of who the ultimate beneficiary is.
1. Building a proprietary campaign management platform with novel algorithmic components
A performance marketing agency spent 18 months developing an internal bidding optimisation tool that connected multiple advertising APIs and applied a proprietary attribution model to dynamically reallocate budget across channels in real time. The algorithmic approach was novel — no existing product on the market used the same methodology for this specific use case. The development involved significant experimentation around the model's weighting logic and multiple iterations that were abandoned before the current approach was settled on. The agency's developers spent approximately 40% of their time on this project. That proportion of their salary costs qualifies, as does a portion of the cloud infrastructure costs. This is a legitimate R&D claim because the technical uncertainty was genuine and well-evidenced.
2. Developing a real-time personalisation engine for a publisher client that required novel technical architecture
A digital agency was commissioned to build a personalisation layer for a major publisher's website that would serve dynamically assembled content in under 200ms — a latency requirement that ruled out all existing off-the-shelf personalisation solutions. The technical challenge was to build a caching and assembly system that could compose unique page variants at scale without a perceptible latency penalty. The team spent several months on architecture experimentation before arriving at a working approach that had not previously been documented in the industry. The qualifying R&D is in the technical problem-solving — the work that involved genuine uncertainty, not the surrounding client delivery work. A clear project-by-project split is essential here.
3. Creating a novel computer vision component for an augmented reality application
A creative technology studio developed an AR experience for a retail client that required real-time object detection and overlay rendering on mid-range mobile hardware — a combination of performance constraints and rendering requirements that existing frameworks could not handle without significant custom development. The team resolved several fundamental technical uncertainties around model compression, frame interpolation, and GPU memory management on constrained hardware. The final solution incorporated techniques that had not been combined in this way before. The technical novelty and the iterative, experimental nature of the development process puts this firmly within qualifying R&D territory.
HMRC scrutiny level — high
HMRC has been explicit that digital agencies and creative businesses are in a higher-risk category for R&D compliance. This followed a significant volume of claims from this sector that HMRC found to be overclaimed, incorrectly structured, or based on a misunderstanding of what constitutes technological uncertainty in a creative context.
The consequence is that agency R&D claims are examined more carefully than those from engineering or life sciences businesses. Claims need to be well-documented, specific, and clearly delineated from standard client delivery work. Vague descriptions of "innovative digital solutions" or "cutting-edge creative technology" will not survive scrutiny — HMRC will ask for specific technical detail about what was uncertain, what was tried, and what the outcome was.
This does not mean agencies should not claim — it means they should only claim what genuinely qualifies and should ensure the claim narrative is specific and technically grounded.
Common mistakes digital agencies make
Claiming for client project work that used established frameworks and tools. Building websites, apps, or digital campaigns using established platforms — even complex ones — does not qualify as R&D. The technological uncertainty test requires that the solution was not readily deducible from existing knowledge. Using React, Shopify, WordPress, or standard cloud APIs in sophisticated but conventional ways is not R&D, however impressive the output. This is the most common reason agency R&D claims are rejected or significantly reduced on enquiry.
Describing creative or strategic innovation as technological uncertainty. Developing a novel creative concept, a new brand strategy, or an innovative marketing approach is not R&D for tax purposes. The uncertainty must be technological or scientific in nature — relating to engineering, software architecture, data science, or similar technical domains. Creative excellence and technological uncertainty are different things, and conflating them is a fast route to a rejected claim.
Failing to clearly separate qualifying from non-qualifying project time. Many agencies have some qualifying work — usually in proprietary tool development or technically challenging client work that required genuine innovation. The problem is that this qualifying work is often mixed in with a much larger volume of standard delivery work. A claim that does not clearly delineate these two categories is difficult to defend. The qualifying proportion, properly identified and documented, is a valid claim — but it needs to be ring-fenced carefully.
If your agency develops proprietary tools, platforms, or technology for your own use or to sell as a product — rather than exclusively doing client delivery work — your qualifying position is likely stronger than average. The key question is whether any of that development involved technical uncertainty that required experimentation to resolve.
