Architecture & Engineering
Architecture often involves developing innovative design solutions to meet regulatory and environmental demands. Here, we explore how R&D applies across the sector and the areas where you’ll find R&D within the industry to help you understand if you could be eligible.
Understanding R&D within Architecture
Research and Development (R&D) tax relief is a financial incentive that can be claimed by qualified architectural firms, offering significant financial benefits for innovative projects.
However, navigating the complexities of what qualifies as R&D in architecture can be challenging. To qualify for R&D tax relief architectural projects must meet specific criteria set by HMRC. These criteria require that the work involves an attempt to advance science or technology, which is distinct from routine architectural tasks such as standard design and planning. The key to eligibility lies in addressing technological uncertainties that cannot be easily resolved by a competent professional in the field.

Core Sectors Within Architecture
The six main industry areas that make up architectureExamples of R&D activity in Architecture
- New Building Components
The development of new elements such as facades, canopies, and features in difficult environmental conditions that involve intricate and complex design. - Technical Challenges in Building Performance
Solving previously unaddressed issues related to energy efficiency, thermal performance, or structural integrity. - New Materials and Techniques
Experimenting with novel materials to enhance durability, sustainability, or safety, and developing prototypes to test new construction methods. - Regulatory Compliance
Conducting extensive testing to ensure compliance with building codes and regulations when using innovative materials or techniques.
- Custom AI and Parametric Design Tools
Developing bespoke AI algorithms or parametric design tools to optimise structural efficiency, energy performance, or construction processes. - Advanced BIM Applications
Pioneering the use of Building Information Modeling (BIM) beyond standard industry practices to enhance collaboration, precision, and innovation in design and construction.
What Does This Relief Translate to in Real Terms?
To help bring this into context, we've included a selection of anonymised client examples showing the types of projects that have qualified, along with the level of relief they were able to claim.
What doesn’t count as R&D in architecture
- Aesthetic or stylistic design work
- Market research for building projects
- Standard code compliance and regulatory submissions
- Construction drawings and documentation for production
- Project management and contract administration
- Using off-the-shelf construction materials as intended

The Claim Process
We understand the complications that can often arise when completing an R&D claim, not to mention the significant amount of time it can consume, diverting your attention from driving your innovation forward. That's why we have streamlined a transparent and hassle-free process that follows a step-by-step approach from start to finish.
Throughout your R&D claim process, we maintain open lines of communication tailored to your preferences. Once we have compiled comprehensive technical and financial reports, we take the responsibility of submitting them and proactively follow up with HMRC, leading the communication on your behalf. Often, our next contact with you brings the exhilarating news of success and positive outcomes.
Step 1
We'll gain your authorisation via our client instruction form/NDA. This will enable us to discuss your R&D activities along with your current tax position. This will enable us to discuss your R&D activities along with your current tax position.Step 2
We'll analyse the profit & loss (P&L) statement of the business while facilitating your technical call. This step aims to determine whether your case is feasible from both technical and financial perspectives.Step 3
Once our experts are confident that your case meets the R&D eligibility criteria, we will then gather all the required technical information and financial documentation according to HMRC's standards to support your case.Step 4
At this stage, we initiate a stringent compliance procedure that we have developed in-house to audit your R&D claim application. We verify whether it meets the defined standards before submitting it to HMRC to ensure a positive outcome.Step 5
After conducting a comprehensive review of your R&D claim, including all required documentation, the application will be forwarded to HMRC for further processing.Step 6
Our team maintains continuous contact with HMRC regarding your case. If any queries arise, we address them on your behalf using a highly systematic approach to maximise your outcome while minimising any delays in your repayment.
DSIT Guidelines
The DSIT Guidelines form the foundation for compliance when preparing an R&D claim. In conjunction with the wider scope of HMRC’s guidance in relation to R&D Tax Relief, they set out how to determine whether work qualifies and provide practical examples of how to apply the criteria to evidence R&D within a project. These guidelines should not only underpin the assessment process when compiling a claim but can also be referenced during an enquiry defence if required. By demonstrating to HMRC how a project aligns with the definitions and scenarios outlined, you can clearly evidence that the innovation undertaken qualifies for R&D tax relief. Below are five of the guidelines we most frequently rely on to support qualifying work.
HMRC often reference software development examples throughout its guidance.
Drawing direct comparisons to HMRC’s own examples offers a clear and simple way to evidence compliance in R&D projects, whether relating to a single technical detail or an entire scheme.The following pages set out examples drawn directly from HMRC’s published guidance, which we reference where relevant within our reports.
- Reformed Reliefs: Overseas Restrictions
- Technological or Scientific Uncertainties
A company is conducting R&D in the development of a software service for the commercial banking market in the US. Development requires the company to have a collocated team in the US due to access regulations within the US banking sector. This requires conditions (the presence of US banking systems and regulatory requirements) which are not present in the UK, and which would be wholly unreasonable to replicate.
This condition exists in the US. Therefore, this activity would satisfy CTA09/1138A if undertaken in the US, where the necessary conditions arise. Under the new ‘merged’ R&D scheme, overseas costs that used to be claimable may be blocked from a claim and so it’s important to ensure your work remains compliant in the modern R&D landscape.
CIRD152000, Example 5
In determining the relevance of your R&D work, we firstly assess whether the work advances your field of science of technology, however we then need to consider what makes your work technologically or scientifically uncertain. A technological or scientific uncertainty exists when knowledge of whether something is scientifically possible or technologically feasible, or how to achieve it in practice, is not readily deducible or available by a competent professional working in the field as per S.13 DSIT guidelines.

Managing Enquiries - Case Studies?
The following examples illustrate how investing in R&D can deliver tangible results, especially in complex software projects. They are presented from a tax perspective rather than a technical viewpoint, explaining projects in a way that HMRC will recognise and accept, rather than using traditional industry language. Each study focuses on how the project is described, rather than providing a full breakdown of the DSIT guidelines applied. For further detail, more comprehensive case studies are available on the Wilby Jones website.
