From both sides: R&D in the engineering consultancy and construction

In summary

• R&D in engineering consultancies is common but typically embedded within live projects rather than formal programmes, with much of it going unrecognised  
• The core challenge for most firms is not generating R&D, but identifying, evidencing and capturing it consistently for tax purposes 
• People, not just processes, are the key to accurately identifying and defining R&D activity 
• Advisers who can engage with engineers on a technical level can help translate complex engineering work into robust and defensible claims  

Engineering consultancies operate in one of the most demanding environments of any sector. Firms must balance tight, fee-driven delivery models with rising expectations around sustainability, performance and technical sophistication.  

Projects are often multi-disciplinary and geographically dispersed, spanning different regulatory frameworks, while technology is changing rapidly. Clients expect timely and cost-effective solutions. 

The constraints firms face are real, but they can also be powerful drivers of innovation. Where there is pressure to solve complex problems and an appetite to move beyond established solutions, meaningful R&D often emerges. 

Consequently, despite a backdrop of uncertainty, many leading firms are experiencing strong growth, driven by demand for low-carbon design, renewable energy and sustainable infrastructure.  

What differentiates the best organisations is not simply the scale or nature of the work they deliver, but their attitude to innovation and how they approach R&D. Some take a lower-risk approach, avoiding technical uncertainty and complex delivery to manage cost and protect fine margins. Others recognise that embracing technical challenges can lead to higher-value projects, stronger reputations and better retention of the best engineers.  

In the latter, R&D activity is most prevalent, but 

it does not occur separately from delivery. Instead, it is a natural by-product of a commercial appetite for solving technical challenges within complex projects.  

The real question for these engineering businesses is not whether R&D is happening (because it must). It is whether the business is capturing it effectively and using it as a strategic advantage. 

R&D in the engineering sector rarely looks the way people expect it to. It does not sit neatly within dedicated innovation teams or ring-fenced budgets. Instead, it arises organically in reaction to real challenges within live projects, often under significant commercial and time pressure. 

For example, ongoing fee constraints have triggered the development of parametric and automated design tools to improve efficiency. Multi-disciplinary delivery encourages more integrated, system-level design approaches. Environmental targets, meanwhile, lead to advances in materials selection, modelling, and performance-driven design. Client conservatism leads to more rigorous validation and testing of new ideas. 

As a result, across the sector, much of this activity is still often classified internally as business as usual rather than recognised as R&D. 

Combined with increased scrutiny from HMRC and media coverage of spurious claims, this has led some organisations to fail to identify anything beyond the most obvious R&D projects.  

There are genuine difficulties in quantifying R&D – in clearly identifying eligible activity, defining its boundaries and evidencing the associated costs.  

Most engineering businesses are not short on innovation, but they lack structured processes to recognise and capture it consistently and efficiently.  

Work involving significant technological uncertainty is often viewed simply as part of the engineer’s role as a problem solver. Consequently, the very activities that underpin a strong R&D claim are frequently overlooked or underrepresented. 

Data presents a similar challenge. Engineering businesses generate large volumes of financial and technical information, but it is not typically structured to easily align with R&D requirements. Design iterations, internal development work, and contributions from technical staff cannot always be directly captured in neat records of R&D activity. This creates a disconnect between what happens on a project and what the organisation can evidence for HMRC. 

The issue is compounded in decentralised organisations, when teams’ approaches to identifying R&D can vary significantly across different disciplines, offices and geographies. The overall picture of R&D activity is often fragmented.  

Financial systems, meanwhile, are typically designed to operate in real time, while R&D is often considered retrospectively.  

Without the right structure and guidance, even highly innovative businesses will struggle to consistently recognise and evidence their R&D. 

People, data, and expertise need to come together to identify and articulate R&D in a way that is both accurate and defendable. 

One of the biggest misconceptions regarding R&D tax claims is that they are fundamentally a systems issue. 

However, defining R&D ultimately relies on the judgement of an organisation’s competent professional – someone capable of assessing whether work advances beyond the current state of knowledge.  

That judgement cannot be automated or replaced by process alone.  

What’s needed is a structured approach to engaging the right individuals within the business. That requires both: 

• Competent professionals who understand the project’s technical challenges in detail and are confident in identifying and shortlisting R&D activity 
• Leadership that consistently reinforces the impact and importance of R&D to the organisation (not just the R&D tax relief claim) 

Internal R&D champions, sustained messaging from senior leadership and regular R&D knowledge-sharing workshops are all tools that can embed a broader understanding and awareness of R&D eligibility. 

R&D advisers, with the technical depth to translate complex engineering work into robust and defendable R&D positions, also support this. Many of us have worked on site ourselves and experience across multiple clients gives us a unique perspective when we partner with technical teams to review their projects. 

Once people are engaged, processes naturally become more effective. 

These processes should not require wholesale operational changes, either. Clunky processes designed with only the R&D claim in mind are likely to alienate engineers. It is far more effective  

to build around existing financial and operational systems rather than replace them.  

Our approach is to ensure that the R&D methodology sits within the organisation’s existing data structures and workflows rather than disrupting them. This 

improves accuracy without creating unnecessary friction.   

Importantly, the most successful implementations are also achieved incrementally. Rather than attempting to design a perfect system from the outset, the process evolves over time, improving alongside the organisation’s understanding of R&D. 

A phased approach is often far more effective and sustainable than a complete transformation. 

Throughout, advisers can play a critical role.  

The most effective advisers do more than interpret legislation; they understand the project itself. They can engage with engineers on technical nuances, challenge assumptions and identify where genuine advancement has occurred. 

At S&W, our engineering specialists bring discipline-specific engineering expertise, as well as genuine curiosity about the work itself. We don’t just match engineers with engineers; we aim to match engineering specialisms with our clients, whether that’s bridges, mechanical systems, materials, tunnels or whatever else.  

This means conversations are grounded in projects’ technical reality, rather than being purely compliance-driven. This helps us to build trusted relationships over time that enable more effective identification of R&D. 

When R&D tax processes are embedded effectively, the benefits extend far beyond compliance, bringing 

tangible value across the business: 

• Improved financial forecasting, with R&D benefits factored into revenue margins 
• Stronger engagement from technical teams, who see their innovative work recognised 
• More informed decision making, particularly around speculative or high-risk work. 
• Greater organisational consistency, with R&D embedded into annual operations. 
• Crucially, R&D benefits can be reinvested into further innovation initiatives, creating a more self-sustaining cycle of improvement. 

The engineering sector is undergoing a period of sustained transformation, with the transition to a low-carbon economy, increasing regulatory complexity, and rapid technological advancements reshaping how projects are delivered. 

In this context, innovation is not optional. 

R&D Tax Relief should be viewed in the same way: not as a financial windfall, but as a mechanism that supports and reinforces innovation within the business. 

The firms that will outperform are those that treat R&D tax as a strategic capability, rather than a year end exercise.
