Founded in 2016 to address a gap in the market, we were built on strong multi-disciplinary design capability and a deep understanding of complex, regulated environments. Today, our expertise extends beyond utilities alone, supporting a wide range of infrastructure and built-environment projects from concept through to delivery.
As a dedicated design house, we combine engineering excellence with clear thinking and collaborative delivery. Our teams bring specialist knowledge, practical insight and a future-focused mindset to every project, helping clients reduce risk, navigate complexity and deliver solutions that are compliant, resilient and built to last.
Work runs through set stages with internal QA and senior sign-off before anything is issued. You know what's coming and when, and drawings don't arrive unchecked.
Accredited under GIRS, NERS and WIRS, with designs written for the DNO, IDNO or water company that has to approve them. Fewer rejections, fewer resubmissions, less time lost at the approval stage.
Bring in EHV, earthing, drainage or renewables expertise for the projects that call for it, without carrying that specialism in-house year round. Scale up on a complex scheme, scale back when it's done.
Gas, water, electrical, earthing and civil under a single instruction, so the design sits in one place with one point of accountability rather than tracked across several suppliers.
From residential schemes to grid-scale energy infrastructure, we work where technical detail and coordination decide whether the programme holds.
Design is all we do. With no construction arm, there's nothing commercial sitting behind our advice, so when we say a route won't work or a specification needs changing, that's the engineering talking.
We work inside our clients' processes rather than alongside them, learning how a team already runs before proposing changes to it. On most projects we're coordinating between developers, EPCs, contractors, DNOs and adopting authorities, and getting those parties aligned early is often what decides the programme.
A clash is cheap to fix on a drawing and expensive to fix on site. Ground conditions, route constraints and equipment interfaces get resolved before construction, which is why our packs go through review rather than around it.
Our work connects renewable generation and storage to the grid: roughly 1,200 MWh of battery storage and 200 MW of solar connections in the last two years, plus substation design that integrates energy infrastructure into land still in agricultural use. We're ISO 14001 certified.
We support Incorporated and Chartered Engineer registration. A team spanning 25+ nationalities and seven offices works to one technical standard.
From residential schemes to grid-scale energy infrastructure, we work where technical detail and coordination decide whether the programme holds.
Multi-utility design for housing schemes, from single-plot connections through to developments of 2,000+ plots, taken through to adoption by the nominated IDNO, IGT or NAV
Electrical and multi-utility design for warehousing, retail, mixed-use and EV charging infrastructure, including private network design and DNO submission.
EHV design up to 275kV, solar farm and BESS substations, and full civil packages for grid-scale storage, delivered across all six UK DNOs and NGET.
From your first conversation to project completion, DACI works as an extension of your team providing trusted engineering expertise, coordinated delivery, and dependable support every step of the way.
