Why work with us

We believe there are many reasons to work with us, but here’s our top 10!

1. Sustainability: We lead the way in sustainable and environmental design. We shape local authority policy and tailor carbon management plans to our clients' needs, putting sustainability at the core of our designs.
2. Heat Network Specialists: We have a strong track record of technical excellence in the heat network and decarbonization sectors. We have pioneered many of the best practice principles in these areas. Our expertise includes optimizing central plant operations, addressing site power challenges, liaising with DNO, considering network temperatures, providing prefabricated packaged plant solutions, implementing fabric interventions, and possessing in-depth knowledge of existing and emerging technologies such as ASHPs, WSHPs, GSHPs, etc.
3. Commercial Acumen: We consistently assume a pivotal commercial control role in our projects, carefully evaluating CAPEX, OPEX, and life cycle cost, while actively seeking out optioneering and value engineering opportunities to ensure our clients receive the utmost value. Furthermore, we expertly manage crucial cost-related project elements, including budget preparation, funding applications, tender analysis, contractor selection, and contractor valuations.
4. Project Management: While our technical ability and engineering expertise are sources of pride, we also excel in the role of overall project manager, overseeing the design team, including the architect, structural engineer, and planning consultant. This is particularly relevant for projects with a focus on MEP and/or decarbonization, such as heat network installations, where we can ensure efficient and successful outcomes.
5. International Accreditation: We are proud to be certified and registered with esteemed international professional institutions such as CIBSE, showcasing our unparalleled technical expertise in this field.
6. Design Rationalisation: At the core of our work is practical and pragmatic engineering. We firmly reject over-engineering and instead prioritize the application of best-practice design principles such as size optimization, storage optimization, flow and temperature optimization, and appropriate usage diversity. This approach guarantees that our proposed solutions are precisely tailored to the task at hand, enabling installations to function at peak efficiency while keeping CAPEX expenditure to a minimum.
7. BIM Expertise: We take pride in our extensive in-house BIM team with expertise across all RIBA stages, from concept to handover. Our diverse client base includes developers, local authorities, contractors, and building operators, allowing us to accumulate best-in-class BIM knowledge. We have the in-house abilities to produce the most detailed 3D modelling information.
8. Strategic Delivery Expertise: In the decarbonization and heat network sectors, our projects are executed on live sites, where maintaining regular business operations is essential to our clients. This is particularly critical in healthcare settings such as hospitals. With our expertise, we have successfully managed live projects under demanding operational conditions and can offer "Keep Live" design solutions to minimize or eliminate disruptions to day-to-day site operations.
9. Delivering and Verifying Operational Savings: Maximizing energy and carbon savings during the design phase is essential, but ensuring these savings are realized during the operational phase is just as critical. Our rigorous witness testing before handover guarantees that the systems are installed according to design specifications and commissioned in adherence to best practices. Additionally, we provide support for measuring and verifying the actual savings during the operational phase.
10. ‘Big Picture’ Thinking: As design engineers, we possess the unique ability to zoom out from the finer details and focus on the broader aspects of a project when needed. By consistently evaluating project outputs in alignment with the overall project objectives, we ensure that we deliver maximum value to our clients, prioritizing their overarching goals over minor elements.
